Mburu J;, Karanja-Lumumba T;, Mwai OA. "Determinants of transaction costs in group-based breeding approaches: the case of dairy goats in the eastern Kenyan highlands."; 2008. Abstract

Exotic dairy goats were introduced in the eastern Kenyan highlands by FARM- Africa through a group-based approach about a decad e ago. Interested farmers had to organize themselves into legally recognized farmers’ groups which would then register with dairy goat breeding stations est ablished by this international non-governmental organization. It was only after su ch a collective action process that individual farmers accessed Toggenburg bucks ( imported from Europe), local markets for kids and milk, and dairy goats’ h usbandry techniques. This process made local communities incur several catego ries of transaction costs whose huge magnitudes hindered some poor farmers fr om participating in the dairy goat breeding activities. It is also expected that transaction costs were induced by transaction attributes, e.g. asset speci ficity, bounded rationality, etc. that are to a large extent dependent on farmers’ so cio-economic conditions and farm characteristics. The relevance of these factor s in determining magnitudes of transaction costs in group-based small ruminants br eeding approaches has not been so far extensively investigated. This is parti cularly so in the developing world. Using a case study of 165 randomly selected farmers in the Kenyan highlands’ Meru District this paper analyzes determ inants of transaction costs of farmers’ participation in dairy goat breeding activ ities. The paper uses econometric analyses to generate these factors and derives important policy implications that would positively influence future targeting strategies in dairy goat breeding programmes in Kenya.

Objective: To determine the prevalence and pattern of eye diseases and visual impairment in the Nairobi Comprehensive Eye Care Services (NCES) Project; the catchment area of the Mbagathi District Eye Unit of Nairobi. Design: Community based survey conducted from October 15th to 31st 2007 Setting: Kibera and Dagoreti divisions of Nairobi City Subjects: 4200 people of all ages were randomly selected; 4056 were examined (96.6% response rate). 122 (2.9%) were not available and 15 (0.4%) declined to be examined. Results: Females: 54.2%, Males: 45.8%. Mean age; 22.4 years, SD; 16.5. Only 241(5.9%) aged >50years old. The leading eye disorders in Kibera and Dagoretti divisions are conjunctival disorders including allergic conjunctivitis and conjunctival growths. This was found to affect 7.6% of the subjects. This was followed by refractive errors found in 5.3% of the subjects. Cataract was found in 30 subjects (0.7%). Disorders of the retina and the optic nerve were found in 1.1% of the subjects and corneal disorders in 0.5%. The prevalence of visual impairment was 0.6%, severe visual impairment was 0.05% and blindness was 0.1%. This indicates that most of the ocular disorders encountered were not visually threatening. The main cause of visual impairment is refractive errors and the causes of severe visual impairment and blindness are cataract, corneal opacity and glaucoma. Conclusion: The population of the NCES is relatively young and the prevalence of blindness and visual impairment is low. The main cause of visual impairment was refractive errors and the causes of severe visual impairment and blindness were cataract, corneal opacity and glaucoma. Recommendations: The level of blindness in NCES is low and the project should focus more on rendering eye care and not treatment of blindness. There is need to address the issue of refractive errors as this was one of the main ocular problems encountered. In this survey, it was not possible to perform detailed refraction and hence it was recommend that a refractive error survey be conducted; especially in school going children.

G. KJ, I. MJ, N. WR, L TC. "Determination of Deltamethrin Residue Levels in Selected Vegetables Consumed in Nairobi, Kenya using HPLC." Journal of International; Published by Environmental Application & Science . 2010;5(1)(11-ICCA Special Issue):801-805. Abstract

Abstract Vegetables provide vital minerals and other nutrients to our bodies.
However, pests destroy vegetables. This as lead to rampant use of pesticides on
vegetables in Kenya. The pesticides that are commonly used on vegetables in
Kenya are the pyrethroids which include; deltamethrin, lambda-cyhalothrin and
chismethrin. In this study deltamethrin was analysed in selected vegetables which
include; kales, cabbages and tomatoes during the dry and wet seasons. The
vegetables were bought from some markets in Nairobi city in Kenya.
Deltamethrin residues were extracted from the samples using organic solvents.
The residues were then determined by high performance liquid chromatography
1
(HPLC). The results shows that the deltamethrin mean residue levels ranged
between 0.0700±0.0200 and 0.2000±0.1000 mg/kg during the dry season and
between 0.0080±0.0500 and 0.0400±0.0001 mg/kg during the wet season. The
deltamethrin residue levels were significantly higher during the wet season than
during the wet season in most of the samples.
Keywords: Vegetables, pyrethroids, deltamethrin, residues and HPLC

This study determined the prey base for four main carnivores found in Samburu Community group ranches and grazing area, Lion (Panthera leo), Leopard (Panthera pardus), Wild dog (Lycaon pictus) and Hyaena (Crocuta crocuta, and Hyaena hyaena). A total of 96 scat samples including, 8 from Lion, 16 Leopards', 2 Wild dogs', and 70 Hyaenas' were collected, identified and microscopically analyzed for prey hair characterisation. At least 50 different hairs from every scat sample were mounted on slides and microscopically characterized using details from reference hairs. Hairs from 18 depredated species both domestic and wild ungulates were recovered from the scat samples. Predated species were identified, as either domestic (Cow, Sheep, Goat, Donkey, and Camel) or wild ungulate prey (Grant's gazelle, plain zebra, Grevy's Zebra, Impala, Waterbuck, Dikdik, Eland, lesser Kudu, greater Kudu, Baboon, rock Hyraxes, Elephant and Oryx). The carnivores showed a relatively high kill of wild ungulate prey compared to domestic prey. Camel was the most preferred cow and donkey respectively. Grevy's zebra contributed highest to the lion's diet while the Plain zebra was most preferred by the leopard. Both the hyaena and Wild dog had a preference for the waterbuck. The Hyaena had the highest domestic depredation, while all the other big cats depredated more on wild ungulates.

Key words: Scat, group ranch, domestic, wild ungulate, prey, depredation.

N PROFKAMAUGEOFREY. "Determination of fluoride in different toothpaste formulations", Kenya J.". In: Sciences series A., 11 (1), 133. Survey Review; 1998. Abstract
Ground Flowers of Matricaria Recutita (German Chamomile) Banat Variety grown in Kenya, were subjected to Clevenger distillation under varying temperature, distillation, pressure conditions and the yields assessed. An inert solvent being present in the collecting column of the Clevenger apparatus increases the yield of the oil by reducing dispersion of the blue oil; its presence however, in the distillation flask inhibits the production of the essential oil. Distillation under reduced pressure leads to a decrease in the yield of the oil produced. A break in distillation time especially during the first three hours of distillation also leads to a decrease in the yield of the oil produced.

In: Gabbay R. &Siddique A., ed., Good Governance Issues and Sustainable Development: The Indian Ocean Region (New Delhi: Vedams Books). ISCTRC; 1997. Abstract
Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. 81, 276-281]. The protein (lectin-trypsin complex) was found to be capable of stimulating differentiation of bloodstream trypanosomes in vitro. Using polyclonal antibodies to the complex, we screened a G. fuscipes fuscipes cDNA midgut expression library and identified a putative proteolytic lectin gene. The cDNA encodes a putative mature polypeptide with 274 amino acids (designated Glossina proteolytic lectin, Gpl). The deduced amino acid sequence includes a hydrophobic signal peptide and a highly conserved N-terminal sequence motif. The typical features of serine protease trypsin family of proteins found in the sequence include the His/Asp/Ser active site triad with the conserved residues surrounding it, three pairs of cysteine residues for disulfide bridges and an aspartate residue at the specificity pocket. Expression of the gene in a bacterial expression system yielded a protein (M(r) approximately 32,500). The recombinant protein (Gpl) bound d(+) glucosamine and agglutinated bloodstream-form trypanosomes and rabbit red blood cells. In addition, the protein was found to be capable of inducing transformation of bloodstream-form trypanosomes into procyclic forms in vitro. Antibodies raised against the recombinant protein showed cross-reactivity with the alpha subunit of the lectin-trypsin complex. These results support our earlier hypothesis that this molecule is involved in the establishment of trypanosome infections in tsetse flies.
I.O JUMBA, S.O W. "The determination of mercury in body beauty soaps and creams sold in Kenya and Norway.". In: Kenya J. Sci. Technol (a) 3, 89-91. Association of Africa Universities; 1982. Abstract

flame-less atomic absorption spcctropholometry technique lias been used to determine mercury concentrations in 14 skin-lightening creams and soaps commonly sold in the Kenyan market and 10 in the Norwegian market. The use of borohydride or stannous chloride as the reducing agents for mercuric salts gave different results. When slannous chloride was used as the reducing agent the range of mercury content was 222 to 4920 jjg/kg. When borohydride was used as the reducing agent the range of mercury content was 0.95 to 1121.86 |jg/kg. The difference in results has been attributed to the difference in digestion modes and the ability of the boric acid to encapsulate the mercuric salts. In general the Kenya products had slightly higher mercury content.

Thabano JRE, bong’o DA, Sawula GM. "Determination of nitrate by suppressed ion chromatography after copperised-cadmium column reduction." Journal of Chromatography A. 2004;1045(1):153-159. AbstractFull text link

The nitrate-selective copperised-cadmium (Cu-Cd) reduction reaction coupled directly to the highly sensitive nitrite ion chromatographic detection, produced a more precise method for determination of nitrate than any one of the two conventional methods. A borate buffer solution used in the reduction reaction, in place of the conventional ammonium–EDTA buffer solution, eliminated interferences from co-eluting ions in the subsequent ion chromatographic detection of nitrite. Optimised experimental conditions included using a packed-bed Cu-Cd reductor column length of 12.5 cm, a solution flow rate of 3.0 ml/min, and using 10.0 ml of borate buffer solution for each 20.0 ml of nitrate-containing solution. Precision was high for results obtained within a greatly extended linear dynamic range of 0.006–1.20 mg/l NO3−, with a much lower limit of detection of 0.40 μg/l NO3−. Cu-Cd reductor column efficiency was 98.20 ± 6.03%. Validation of the method was undertaken using certified reference materials. The method was successfully applied to analysis of dam water, river water and storm water samples, producing more precise results than either the conventional colorimetric method or the conventional ion chromatographic method.

The world is today faced with the global pandemic of HIV/AIDS that has evolved rapidly since it was first described. The pandemic has been termed the greatest development challenge for sub Saharan Africa and is rapidly evolving in the Asian continent. The pandemic ha had a significantly negative impact on individual families through loss of loved ones, communities by increasing the burden of caring for the ill, and countries through reduced productivity.     As we look forward to the 21st century, the human population is reminded that even in an age where drugs to treat most ailments are available, human behaviour and individual aspirations are critical in the control of disease. Factors that affect human and social behaviour, such as poverty, discrimination and disenfranchisement have to be addressed on a global basis if the HIV/AIDS epidemic is to be controlled. The HIV/AIDS epidemic presents special challenges and new frontiers for public health interventions and research. HIV/AIDS has revealed the gaps in the understanding of how human behaviour is motivated and how it can be changed.     In this publication we present a review of some of the programs that are specifically targeting the youth with HIV/AIDS prevention activities in the countries of   This publication records the stories of men and women in Eastern Africa, who have tremendous commitment to the work they do even with minimal resources, because they have a vision for the youth of the African continent. It is a story of innovation, creativity, determination and partnership between adults and youth, communities and governments, countries, aid agencies and NGOSs.

Ultrasound technology has become an important aspect in material handling and machining. Standing and traveling ultrasonic waves have been applied in powder transportation, feeding, dosing and supply of small amounts of powder with high quantitative accuracy and precision. Piezoelectric actuators are the most commonly used to generate the ultrasonic waves in various devices. Hence, these devices have presented a unique, economic and simple means of accurate handling of powder. This paper describes the determination of the resonant frequency of a piezoelectric ring that can be applied for generation of the ultrasonic waves. The resonant frequency is important in determining the highest amplitude of the vibration of the ring.

The overall objective of the study is to determine parasite carriage of village chicken of Mbeere district, Eastern province of Kenya. The study was conducted for over two seasons, the dry (January to March) and wet (October to December) season. Subsequently efficacy testing of selected antiparasitic drugs will be conducted. Twenty four birds of three age groups (chicks, growers and adults) were randomly selected from homesteads. The study showed that all chicken (100%) harboured ecto and endoparasites and 79.1% were infected with haemoparasites. With respect to ectoparasites, all the birds (100%) were infested, with lice, while 75% were infected with mites, 66.7% with ticks and 54.1% with fleas. The most prevalent nematodes were the caecal worms (91.7%), Tetramere species (54.1%), Gonglylonema (29.1%) and Coccidial oocyst (20.8%). Cestodes were also present in 91.7% of the samples. Haemoparasites had a prevalence of 83.3%. This study has shown that endo and ectoparasites are a common health problem in the village chicken in Mbeere District, Kenya. The studies for wet season and for drug sensitivity testing are still on-going.

Dulo SO. "Determination of some Physico-chemical parameters of the Nairobi River, Kenya.". 2003. AbstractWebsite

This paper discusses the results of a study carried out in 2003 on the water quality of Nairobi River on the basis of pollution parameters and water quality index. The study aimed at establishing whether the water meets the surface water quality criteria for water supply. The area of study in Nairobi River was within its entry and exit of Nairobi province. It was observed that human activities along the river with visible encroachment to the banks, contribute to the heavy level of pollution of the river. This is the section that industrial discharges and municipal sewerage are discharged into the river. The study was carried out through field surveys and laboratory tests on samples taken from the river. The results obtained from laboratory tests were analysed and compared to the established surface water quality criteria by A.S.C.E, W.H.O, Natural watercourses Standards of Kenya and classification of rivers by Royal Commission on Sewage Disposal. Human activities along the river course have severely impacted on the River water quality. The study area had average pH of 7.04; the average turbidity was 41.5N.T.U, the average suspended solids in the section was 116.43 mg/l, the average dissolved oxygen was 4.32mg/l. the average BOD was 182.5mg/l. The average COD for the reach studied was 49.5mg/l. The river was therefore classified as bad according to Klein 1966. The study concluded that the Nairobi River within Nairobi province was badly polluted as indicated by the water quality index analysis. The WQI gives a value of 49.27, fall between the numerical ranges of the classification of bad (26-50).

Mulwa JK, Kimata F. "Determination of source parameters for the May 20, 1990 Southern Sudan earthquake by inversion of teleseismic body-waves.". In: Operating Management of Earthquake, Tsunami and Volcano Eruption Observation Systems. Nagoya: Research Center for Seismology, Volcanology and Disaster Mitigation, Nagoya University; 2011. Abstract

The May 20, 1990 earthquake which occurred in southern Sudan is so far the strongest earthquake to occur in the eastern part of African continent within the past 21 years. It caused damage in southern Sudan as well as severe shaking in parts of Uganda and Kenya, and was accompanied by aftershocks on May 24, 1990 of moment magnitudes Mw = 6.5 and 7.1.

Inversion of teleseismic body-waves has been undertaken for the purpose of this study in an attempt to reassess the seismo-tectonics of northern and central Kenya as well as southern Sudan. The results show that the best solution for the inversion of teleseismic body waves for the May 20, 1990 earthquake consists of only one event with a source mechanism of 315o/84o/-3o (strike/dip/rake) and the fault plane is characterized by left-lateral strike-slip fault mechanism. The focal depth for this earthquake is 12.1 km, seismic moment Mo = 7.65 x 1019 Nm and moment magnitude, Mw = 7.19 (7.2). The fault rupture started 15 seconds earlier and lasted for a duration of 17 seconds along a fault plane having dimensions of length  60 km and width  40 km. The average dislocation along the fault is 1.1 m and the stress drop,  is 1.63 Mpa.

The distribution of historical earthquakes from southern Sudan through central Kenya shows a NW-SE alignment of epicenters. On a local scale in Kenya, the NW-SE alignment of epicenters is characterized by earthquakes of local magnitude Ml  4.0. This NW-SE alignment of epicenters confirms the existence of an active fault zone, the Aswa-Nyangia fault zone, from southern Sudan through central Kenya and further into the Indian Ocean. However, owing to lack of waveform data for these historical earthquakes, it is not possible to determine the source mechanism of the fault. Further work on inversion of short period waveform data is required so as to precisely determine the fault mechanism of this NW-SE trending fault zone in the central and southeastern parts of Kenya.

Between June and December 1992 forty AIDS patients as defined by the CDC criteria, admitted to the medical wards of the Kenyatta National Hospital, were studied to determine the prevalence and pattern of peripheral neuropathy. Their mean age was 33 +/- 3 years with a range of 16 to 55 years. Clinical and laboratory assessment were carried out both to confirm peripheral neuropathy and exclude other causes of peripheral neuropathy apart from AIDS. All the patients had nerve conduction and electromyographic studies done. Eighteen patients were asymptomatic while fourteen had both signs and symptoms. The commonest symptom was painful paresthesiae of the limbs (35%) while the commonest sign was loss of vibration sense (60%). When symptoms, signs, and electrophysiological studies were combined, all the patients fitted the definition of peripheral neuropathy. The commonest type of peripheral neuropathy was distal symmetrical peripheral neuropathy (DSPN) (37.5%). PIP: In Kenya, physicians evaluated 40 AIDS patients admitted to Kenyatta National Hospital during June-December 1992 to determine the prevalence and types of peripheral neuropathy in AIDS patients. 75% were 21-40 years old. 18 (45%) of the 40 AIDS patients had symptoms of peripheral neuropathy. Symptoms included increased sensitivity to stimulation (43%), hyperpathia (15%), and muscle or limb weakness (13%). 26 AIDS patients had signs of peripheral neuropathy, especially impaired sense of vibration (60%). 14 of these patients had both signs and symptoms. Electromyographic and nerve conduction velocity revealed peripheral neuropathy in 16 (40%) AIDS patients. The types of peripheral neuropathy included distal symmetrical peripheral neuropathy (37.5%), polyneuropathy, and mononeuritis multiplex. When the symptoms, signs, and electroneurophysiological test findings were considered, all 40 AIDS patients had evidence of peripheral neuropathy.

"Determination of the Coefficient of Correlation Between Radiation and Relative Humidity, and Determining Equation of the Line of Best Fit Using Statistical Methods." 2nd UN/NASA Workshop on International Heliophysical Year and Basic Space Science. 2006:81. AbstractSAO/NASA Astrophysics Data System

This paper investigates the inter-relationship between solar radiation intensity RD and relative humidity RH in Kenya using daily data obtained at five meteorological stations; Nairobi (1.3°S, 36.75°E), Kericho (0.37˚S, 35.72˚E), Kisumu (0.10˚S, 34.75˚E), Mombasa (4.03˚S, 39.65˚E) and Garissa (0.48˚S, 39.63˚E) during the solar minimum year 1986. Statistical methods were employed and the coefficients of correlation, r obtained range from 0.16094 to -0.6758618 between the two variables for the five stations. The linear equation relating the solar radiation intensity RD to relative humidity RH is obtained using linear regression analysis as RH = 109.1091-1.5997RD for the Nairobi station. Jandel scientific and Megastat software analyses gave fairly similar trends of results for Nairobi and other stations, and for all the seasons except for those of Garissa station. Obviously there exists a negative interdependence between solar radiation intensity and relative humidity such that the relative humidity decreases as solar radiation increases and vice versa. This observation is explicable in terms of the dynamics of atmospheric heating and advection traceable to solar activity.

Omuga DB. "Determination Of The Daily Nursing Procedures Performed To Children Admitted With Medical Conditions At Kenyatta National Hospital, Kenya." Kenya Nursing Journal. 2011;39(2):16-23. Abstract

Abstract
The daily nursing procedures are those aspects of nursing that occur most frequently, affect a large number of patients andplace patients at ·riskby not providing care correctly or providing care that is not indicated. There has been an increasing outcry of falling standards of health care in hospitals. Many a times health care providers including the nurse do not follow recommended procedures or do not carry out required tasks at all. Checks on procedures performed to hospitalized children and their parents has been documented as one way of evaluating the quality of care. This was a descriptive cross-sectional study carried at KNHwith the aim of determining the daily nursing procedures and the adherence to oral drug administration' procedure. The children whose parents/ guardians participated in the study were selected through systematic random
sampling using the admission registers while the nurses were purposely selected. A total of 256 parents/guardians staying with the selected children, 78 nurses and 4 nurse in- charges were recruited into the study. Data was analysed by use of the "Statistical Package for Social Science (SPSS)".Drug administration was established as one of the procedures that almost all nurses carried out on a daily basis. However, the procedure for administration of oral medications was not adhered to by all the nurses observed. Other daily procedure.s.mentioned invariably included nutritional care (50%),hygiene (50%),taking of
vital observations (46.4%),comfort caring (44%);health education (36%)and infection control (2.5%).It was concluded that there is minimal performance of the expected daily nursing procedures and non-adherence to the laid down procedures for the administration of oral medications thus indicating that the quality of care is sub-optimal. The study recommended that standards of paediatric nursing be developed and emphasis be laid on the performance of the daily procedures and adherence to the laid procedures for oral drug administration to minimize drug errors.

The sample is ashed in a nickel crucible over an open flame with calcium hydroxide as thefixative; fluoride is separated by micro-diffusion and measured with a fluoride-selective electrode.The calcium hydroxide fixative permits a temperature of 800—850°C during the final ashing, sothat insoluble silicates are decomposed and fluoride is converted to an acid-soluble form. Otheradvantages over furnace ashing at 600°C are less contamination and more rapid ashing (20 mincompared to 6 h). The interference of aluminium and silica on microdiffusion was studied: per-chloric acid was found to be preferable to sulphuric acid as medium. A new way for preparingcalcium hydroxide suspension, low in fluoride, is described. The values found by the proposedmethod generally compare well with those obtained by oxygen flask combustion. Direct diffusion(i.e. without ashing) gave much lower values than the ashing methods, except for tea leaves.

Preliminary results of trace element analysis by TXRF of drinking tap water, various brands of local and imported bottled water samples sold in Nairobi as mineral are presented. The levels of potassium(K) ranged from 0.2 to 28.9 μg/ml, calcium(Ca) 2.2 to 120 μg/ml, titanium(Ti) 11 to 60 μg/l, manganese(Mn)8 to 670 μg/l, iron(Fe)31 to 50 μg/l, copper(Cu) 8 to 30 μg/l, bromine(Br) 9 to 248 μg/l, rubidium(Rb )10 to 40 μg/l, and strontium(Sr)10 to 1000 μg/l. It was found that the local mineral water samples contained higher levels of trace elements especially Mn, Zn, Br, Rb and Sr compared to the imported brands. Principal component analysis of the results revealed three factors with the highest component loadings clustering Rb, Sr, Ca in the first eigenvalue; Ti, Fe, Br, Zn, in the second; Zn, Mn, K in the third. A limited spread of 5–6 mm for a 10μl samples was achievable by completely drying the quartz Suprasil sample carrier in a low pressure (300mbar) oven at temperature of 70oC for 10 hours.

Fusarium verticillioides and Aspergillus
flavus cause Fusarium ear rot (FER) and Aspergillus
ear rot (AER) of maize, respectively. Both pathogens
are of concern to producers as they reduce grain yield
and affect quality. F. verticillioides and A. flavus also
contaminate maize grain with the mycotoxins fumonisins
and aflatoxins, respectively, which has been
associated with mycotoxicosis in humans and animals.
The occurrence of common resistance mechanisms to
FER and AER has been reported. Hence, ten Kenyan
inbred lines resistant to AER and aflatoxin accumulation
were evaluated for resistance to FER, F.
verticillioides colonisation and fumonisin accumulation;
and compared to nine South African lines
resistant to FER and fumonisin accumulation. Field
trials were conducted at three localities in South Africa
and two localities in Kenya. FER severity was
determined by visual assessment, while F. verticillioides
colonisation and fumonisin content were
quantified by real-time PCR and liquid chromatography
tandem mass spectrometry, respectively. Significant
genotype x environment interactions was
determined at each location (P B 0.05). Kenyan
inbred CML495 was most resistant to FER and F.
verticillioides colonisation, and accumulated the lowest
concentration of fumonisins across localities. It
was, however, not significantly more resistant than
Kenyan lines CML264 and CKL05015, and the South
African line RO549 W, which also exhibited low FER
severity (B5%), fungal target DNA (B0.025 ng lL-1
)
and fumonisin levels (B2.5 mg kg-1
). Inbred lines
resistant to AER and aflatoxin accumulation appear to
be promising sources of resistance to F. verticillioides
and fumonisin contamination.

Zander K;, Mburu J. "Determining Right Priorities for Conserving Farm Animal Genetic Resources — The Case of Borana Cattle in East Africa."; 1985. Abstract

Borana cattle have their origin in Southern Ethiopia and Kenya where they are guarded by the Borana-Oromyfa clans in the harsh environment of the Borana plateau. Borana cattle are also the main source of the livestock-keepers’ income and the local people’s cultural identity is formed on the husbandry of these animals. Nowadays the existence of this breed and hence its cultural heritage is threatened due to intensifying crossbreeding among different breeds and eventually dwindling records of pure Borana animals. Conservation of the pure Borana genetic resources is important for future use and enhancement of biodiversity, but financial aid for conservation initiatives is scarce. This study addresses two crucial topics in conservation theory: the question of “which” Borana animals should be conserved and hence deserve priority in funding, and the question of “who” should conserve them. 370 livestock-keepers on the Borana plateau were selected for conducting semi-structured questionnaires and choice experiments. The models were then analysed using NLOGIT 3.0. The first question is driven by the fact that currently three different subtypes of the Borana breed are known and kept on the Borana plateau. Appropriate allocation of funds among them must take place according to their economic and genetic values. Economic values are determined by applying a discrete choice analysis estimating the livestock-keepers’ willingness to pay and relative preferences for different attributes of the Borana cattle. Genetic values depend on two factors, namely the level of extinction probability and the level of marginal genetic diversity. Both factors are incorporated into the model and together with economic values form the total value of Borana cattle and its subtypes. The question of “who” should participate in conservation initiatives requires the consideration of individual livestock-keepers’ characteristics into the model revealing heterogeneity in livestock-keepers’ preferences and willingness to pay for different cattle attributes. A random parameter logit model is used seeking to establish different groups of livestock-keepers that can be targeted for conserving Borana. Results suggest that Borana cattle are particularly important because of their adaptability and performance attributes and that their values vary significantly among livestock keepers with different production systems and in different areas.

This report concerns an outbreak that occurred during July/August 1997. Ten pigs from a herd of 181 pigs in a medium-scale, semi-closed piggery in Kiambu District, Kenya, contracted the clinical disease. The main clinical findings in affected pigs included: fever (40.5-41.8 degrees C), prostration, inappetence, dog-sitting posture, abortion, erythema and raised, firm to the touch and easily palpated light pink to dark purple diamond-shaped to square/rectangular spots on the skin around the belly and the back. Based on the pathognomonic skin lesions, a clinical diagnosis of swine erysipelas was made. The diagnosis was confirmed by the isolation of Erysipelothrix rhusiopathiae organisms from the blood and skin biopsies taken from the affected pigs. Response to treatment with a combination of procaine penicillin and dihydrostreptomycin at the dosage rate of 20,000 IU/kg body weight (based on procaine penicillin) for 3 days was good and all the affected pigs recovered fully. The farm was placed under quarantine to prevent spread of the disease

Although early diagnosis and treatment are key factors in the effective control of human African trypanosomiasis (HAT), many cases of the disease delay taking appropriate action, leading to untold suffering. As a better understanding of treatment-seeking behaviour should help in identifying the obstacles to early diagnosis and effective treatment, the treatment pathways followed by 203 former HAT cases in western Kenya and eastern Uganda have recently been explored. About 86% of the HAT cases had utilized more than two different healthcare options before being correctly diagnosed for HAT, with about 70% each using more than three different health facilities. Only about 8% of the cases reported that they had been correctly diagnosed the first time they sought treatment. Just over half (51%) of the HAT cases had been symptomatic for >2 months before being correctly diagnosed for HAT, and such time lags in diagnosis contributed to 72% of the cases receiving their first appropriate treatment only in the late stage of the disease. The likelihood of a correct diagnosis increased with the time the case had been symptomatic. These observations indicate an urgent need to build the diagnostic capacity of the primary healthcare facilities in the study area, so that all HAT cases can be identified and treated in the early stage of the disease.

This paper studies the problem of malaria control in irrigation and non-irrigation areas in Kenya. Empirical results show that in both areas, households' level of awareness of malaria as a health problem, including its cause, was very high. However, attempts to trace the direct effects of malaria upon income or upon agricultural production were not statistically important. This does not imply that malaria has no consequence on household welfare. It is possible that the model equations were mis-specified–aggregate variables (total family size, total family income) and failure to quantify land in the production relationships may have contributed to these results. In addition, poor separation of malaria as a disease, from malaria as an infection, may have underestimated the effect of the disease on production. Thirdly, labour substitution (hiring or within-family substitution) was not measured in this early study, but was taken into account in subsequent research. Finally, labour requirements in the annual crop production schedules and the co-relation between these labour requirements and the pattern of adult morbidity were not longitudinally monitored. Cross-section data would bias the findings, particularly in those areas where the peak transmission season is short, where the crop grown does not require major labour input during this transmission season, and where acquisition of immunity would reduce the clinical impact of malaria upon adult labour. These vulnerabilities in the specification of the model and the data collected, probably affect the results obtained. Our empirical work raises a number of interesting and important questions which should be taken into account in future research

Bett B;, Kitala J;, Gathuma J. "Developing a Frame Work for Evaluating Vaccination Strategies Against Foot and Mouth Disease Required for the Establishment of ‘Disease Free Zones’ in Kenya."; 2006. Abstract

Foot and mouth disease is the most economically devastating disease that affects cloven-hoofed animals. In most parts of Kenya, the disease has become endemic because the available control measures (prophylactic or reactive vaccination) are not being applied at an intensity that would curtail the maintenance of the disease. The effectiveness of the control interventions is complicated by factors that reduce vaccination coverage and efficacy; these factors include spatial and host heterogeneities, low rates of uptake of the vaccines and the multiple serotypes of the virus. The conditions necessary for the establishment of disease free zones, given these limitations, are explored using a mathematical model that combines the mass-action transmission principles with spatial correlation structure describing the contact patterns between clusters of cattle and potential reservoirs. Cattle clusters are nested within those of potential reservoirs. The relative contact probabilities between clusters vary depending on the distances between them. The outputs indicate that with a trivalent vaccine, very high vaccination coverage would have to be realized on a regular basis if disease free zones were to be established. This may require a review of the existing cost sharing policy as it is the main cause of the low uptake of prophylactic vaccination.

Shepherd M, Kasem S, Ablett G, Ochieng J, Crawford A. Developing a genetic classification for gene pool management of spotted gums.; 2013. Abstract

Spotted gums (Genus Corymbia Section Politaria) occur as a species replacement series along the eastern seaboard of Australia, their distributions marked by regions of disjunction and sympatry. Their taxonomy remains controversial, with species assignment often challenging and reliant upon knowledge of geographic origin as well as subtle morphological or leaf oil variation. In this paper we explore a classification for spotted gums without assuming predefined geographic or taxonomic groups, instead using genetic structure at microsatellite marker loci (n=9) and a Bayesian model-based clustering approach implemented in STRUCTURE software. The C. torelliana outgroup (n=21; Section Cadagaria) formed a well resolved cluster (min. pairwise Fst = 0.19). Four populations were evident within the spotted gums (n=93) but structure was weak (pairwise Fst range 0.13 -0.05). Geography, both distance and topography were major determinants of structure, with migration among populations approximating a linear stepping-stone model. Corymbia maculata was resolved as a taxon and had the greatest genetic distance to any other population (min pairwise Fst 0.08). Three clusters were evident within the northern taxa but alignment with taxonomic groupings was poor. Corymbia citriodora material from north of a major disjunction in Central Queensland formed a Northern population. Corymbia citriodora, C. variegata and C. henryi material from below this disjunction but north of the Border Ranges, formed a Central population, whereas a Southern population was comprised of C. variegata and C. henryi from predominately south of the Border Ranges. Fewer ambiguous assignments occurred using genetic rather than taxonomic groups for self classification of the spotted gum reference population.

C PROFANYAMBATOMTEBESI. "Developing an Authentic African Architecture." Africa Habitat Review . 2011;5. Abstract

The idea of the existence of an African Architecture has been problematic over the years since the onset of European occupation. Early scholars of non-Western built forms saw them as not constituting architecture but as shelter or mere dwellings (Oliver, 1987). Others classed these built forms as primitive or indigenous architecture (Guidoni, 1987 Gardi, 1973)while others have classed built forms on the African continent as African Architecture (Kultermann, 1969).Globally, most indigenous societies build their structures using local resources and quite often adapted to the climate of the locality. In addition, traditional built forms tend to respect historical precedents and local customary practices. In this regard, it can be argued that traditional architecture is green architecture without the benefits of sophisticated technologies. The above notwithstanding, most Western architecture imported to the continent, had little regard for local practices and quite often ignored local climate. In attempting to train architects for contemporary practice, this paper argues for hybrid architecture. This is because there is no current pure African architecture in existence. What happened over time was the Africanisation of Western and Eastern architectural models to suit the African condition. The resultant architecture has been a hybrid of these various architectures, what Mazrui refers to as the Triple African Heritage. This architecture is a spatial counter form for the contemporary African society and can be seen to be authentic

In this paper, we describe the development of an open source spell checker for Gikuyu language using the Hunspell language tools. We explore the morphology of Gikuyu, highlighting the inflection of various parts of speech in Gikuyu including verbs, nouns, and adjectives among others. In Hunspell, surface words are realized as a set of continuation classes, with each class providing a morpheme with a specific function. In addition, circumfixation, which is prevalent in Gikuyu derived nouns, is implemented. Hunspell also provides for word suggestion using character prevalence and replacement rules. Given that the developed Gikuyu spellchecker and the Hunspell tools are open source, the spell checking function developed in this work can be adopted in major open-source products such as Mozilla and OpenOffice products. The spell checker has a fairly representative Gikuyu lexicon and achieves an acceptable realization of a Gikuyu spellchecker. When tested on a test corpus, the spell checker attains a precision of 82%, recall of 84% and an accuracy of 75%.

Abstract In this paper, we describe the development of an open source spell checker for
Gıkuyu, using the Hunspell language tools. We explore the morphology of Gıkuyu and
highlight the inflection of various parts of speech, including verbs, nouns, and adjectives. In
Hunspell, surface words are realized as a set of continuation classes, with each class
providing a morpheme with a specific function. In addition, circumfixation, which is prevalent
in Gıkuyu, is implemented. Hunspell also provides for word suggestion, using character

A retrospective study of the hospital records revealed that 39 cases of mandibular fractures presented at Kisii District Hospital during a two-year period. 27 cases were due to interpersonal violence while road traffic accidents and accidental falls accounted for 9 and 3 of the cases respectively. The male ratio was 2.9:1. Majority (26 cases) of the patients were aged between 20 and 39 years. The commonly involved fracture site was the left body of the mandible accounting for 20 of the fractures.

Abstractdeveloping_and_introducing_evidence_based_clinical_practice_guidelines_for_serious_illness_in_kenya..pdf

The under-5 mortality rate in most developing countries remains high yet many deaths could be averted if available knowledge was put into practice. For seriously ill children in hospital investigations in low-income countries commonly demonstrate incorrect diagnosis and treatment and frequent prescribing errors. To help improve hospital management of the major causes of inpatient childhood mortality we developed simple clinical guidelines for use in Kenya, a low-income setting. The participatory process we used to adapt existing WHO materials and further develop and build support for such guidelines is discussed. To facilitate use of the guidelines we also developed job-aides and a 5.5 days training programme for their dissemination and implementation. We attempted to base our training on modern theories around adult learning and deliberately attempted to train a ‘critical mass’ of health workers within each institution at low cost. Our experience suggests that with sustained effort it is possible to develop locally owned, appropriate clinical practice guidelines for emergency and initial hospital care for seriously ill children with involvement of pertinent stake holders throughout. Early experience suggests that the training developed to support the guidelines, despite the fact that it challenges many established practices, is well received, appropriate to the needs of front line health workers in Kenya and feasible. To our knowledge the process described in Kenya is among a handful of attempts globally to implement inpatient or referral care components of WHO / UNICEF’s Integrated Management of Childhood Illness approach. However, whether guideline dissemination and implementation result in improved quality of care in our environment remains to be seen.

Major losses in sheep and goats have been incurred from Peste des petit ruminants (PPR), a relatively new disease in East Africa. It first appeared in Eastern Uganda but has since spread to most of Kenya and Northern Tanzania. Small ruminants are the source of income for most pastoralists in East Africa. In this study the epidemiology of PPR including risk factors, prevalence, and socio-economic effects will be analyzed using participatory tools in Turkana, Kenya and Longido in Tanzania.

Abstract
Background/Aims: Clinical cancer genetics is an integral part
of cancer control and management, yet its development as an
essential medical service has been hindered in many low-andmiddle-
income countries. We report our experiences in developing
a clinical cancer genetics service for retinoblastoma in
Kenya. Methods: A genetics task force was created from within
the membership of the existing Kenyan National Retinoblastoma
Strategy group. The task force engaged in multiple inperson
and telephone discussions, delineating experiences,
opinions and suggestions for an evidence-based, culturally
sensitive retinoblastoma genetics service. Discussions were recorded
and thematically categorized to develop a strategy for
the design and implementation of a national retinoblastoma
clinical genetics service. Results: Discussion among the retinoblastoma genetics task force supported the development of a
comprehensive genetics service that rests on 3 pillars: (1) patient
and family counseling, (2) community involvement, and
(3) medical education. Conclusions: A coordinated national
retinoblastoma genetics task force led to the creation of a
unique and relevant approach to delivering comprehensive
and accurate genetic care to Kenyan retinoblastoma patients.
The task force aims to stimulate innovative approaches in cancer
genetics research, education and knowledge translation,
taking advantage of unique opportunities offered in the African
context

Sub-Saharan Africa cancer registries are beset by an increasing cancer burden further exacerbated by the AIDS epidemic where there are limited capabilities for cancer-AIDS match co-registration. We undertook a pilot study based on a "strength-of-evidence" approach using clinical data that is abstracted at the time of cancer registration for purposes of linking cancer diagnosis to AIDS diagnosis.

There are few examples of sustained nationally organised, evidence-informed clinical guidelines development processes in Sub-Saharan Africa. We describe the evolution of efforts from 2005 to 2015 to support evidence-informed decision making to guide admission hospital care practices in Kenya. The approach to conduct reviews, present evidence, and structure and promote transparency of consensus-based procedures for making recommendations improved over four distinct rounds of policy making. Efforts to engage important voices extended from government and academia initially to include multiple professional associations, regulators and practitioners. More than 100 people have been engaged in the decision-making process; an increasing number outside the research team has contributed to the conduct of systematic reviews, and 31 clinical policy recommendations has been developed. Recommendations were incorporated into clinical guideline booklets that have been widely disseminated with a popular knowledge and skills training course. Both helped translate evidence into practice. We contend that these efforts have helped improve the use of evidence to inform policy. The systematic reviews, Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approaches and evidence to decision-making process are well understood by clinicians, and the process has helped create a broad community engaged in evidence translation together with a social or professional norm to use evidence in paediatric care in Kenya. Specific sustained efforts should be made to support capacity and evidence-based decision making in other African settings and clinical disciplines.

"Developing open online learning resources: Lessons from a short course on the control of blindness from diabetic retinopathy.". In: College of Ophthalmologists in Eastern Central & Southern Africa (COECSA). Addis Ababa; 2018. Abstract

Background: A need identified during another study prompted the development of the open online course on control of blindness from diabetic retinopathy. In our technological age, potential for learning online can provide a unique opportunity to develop context-specific content for local relevance. We report on the lessons learnt in the development of this short online course for an international audience of diverse eye care practitioners.

Methods: We developed this online short course through a formal planning process facilitated by UNESCO. The participants included eye health educators, learning designers, and content experts. The course curriculum was informed by learning from an ongoing doctorate program, as well as by clinical, public health and educational experience.

Results: Lessons learnt include:
1. Identifying the need and content – Learning and research from a doctorate research program can inform content development.
2. Identifying the relevance – the content needs to be customized for the target audience and local context.
3. Developing the learning design – promoting digital teaching skills and co-creation of content are valuable entry points.
4. Accommodating appropriate peer review and mentorship may enhance learning and quality assurance.
5. Resource planning activities need to be documented as a learning point.
6. There are significant costs in course development, such as time spent in content development, and ongoing maintenance eg maintaining the online platform.
7. Sources of quality open access resources in eye care are limited.

Conclusion: Content development is a unique learning experience, and it is essential to develop and support context specific learning resources. Open educational practice supports a collaborative process that enhances relevance and quality of training. The online format emphasizes the importance of learning design requirements to bridge the transactional distance between the participant and the educator.

University, Kenya Elijah I. Omwenga University of Nairobi, Kenya Robert Oboko University of
Nairobi, Kenya Ruth Wario University of Free State, South Africa Since technology alone without
the instructor or teacher cannot deliver learning to learners, the presence of the teacher or instructor
is very important. For any meaningful teaching and learning to take place in a class, the teacher
must gain learner's attention. Teachers who use learner centered approaches have a strong
trust in students, they believe that students want to learn, have great faith in student ability and
offer students ownership of class activities. They are able to manage their classroom.

In: issueProceedings of the 5th Biennial Scientific conference, Faculty of Veterinary Medicine, September 6th . University of Nairobi; 1998. Abstract
Seventeen cows of various breeds with varying degrees of severity of advanced ocular squamous cell carcinoma were treated by radical surgery, which included enucleation and extirpation of the surrounding ocular muscles and tissues. The degree of severity and the extent of the carcinoma lesion was correlated with the outcome of treatment for each case. It was observed that: 1. eyeball involvement, 2. ulceration and subsequent infection of carcinoma lesion involving the eyelids and 3. involvement of the regional lymphnodes especially the parotid , are some of the main factors that could be used to draw prognosis of such cases. Although the initial surgery may not be costly, the overall cost of managing postoperative complications is prohibitive and results to vast economic losses that should not be ignored.

The natural product curcumin has a wide range of useful biological effects. However its use in humans is limited due to its short half-life, rapid metabolism and poor oral bioavailability. It is metabolized by sequential reduction of carbon-carbon double two carbonyl groups. To overcome these limitations, a hydrazide derivative of curcumin was synthesized to improve its water solubility and reduce its rate of metabolism. The objective of study was, therefore, to develop a method for the analysis of hydrazinocureumin in murinc blood. This method will be eventually used to evaluate the pharmokinetic profile of hydrazinocurcumin in mice. Method: LC/MS/MS was selected as the analytic method because its high sensitivity allowed for sampling of small volumes of blood from mice. The optimal chromatographic and mass spectrometry conditions were determined by trial arid error. The column performance was monitored by measuring retention time, peak symmetry factor. A calibration curve was generated by using standard solutions with concentrations ranging from 0.78 - 10 rig/ml. The method was validated by determining the recovery, limit of detection, accuracy, linearity and intraday precision. The optimal method for extracting hydrazinocurcumin from biological fluids was determined by spiking human blood and plasma and extraction was done by solvent extraction from a spotted filter paper and liquid-liquid extraction. Instrumentation: The samples were assayed using an Agilent LC/MS/MS 3200Q Trap system (1100 series, USA) in the positive ionization mode. HPLC separation was done using an Agilent 1200 system (Agilent Technologies, Japan) interfaced with the MS/MS system. Ionization was done by electron spray ionization with a collision energy was 33eV. Chromatograms were integrated using Analyst version 1.4 software. Weighted linear regression was used to generate calibration curves from standard solutions. Results: The optimal conditions for HPLC separation was a mobile phase of 0.1% formic acid in acetonitrile: acetonitrile (1:1) with an isocratic flow rate of 0.3m1/minute and run time of 2 minutes. The analytical column was a 50 by 2.0 mm Pheromex C18 column with a particle size of 5 microns. The injection volume was 1 Out The hydrazinocurcumin formed molecular ion at M+H+ m/z 365.2 and two metastable ions at m/z 351 and m/z. 349.2. The transition monitored was m/z 365.2 to 349.2 at unit resolution and a dwelling time of 150 milliseconds. The retention time was 1.11 minutes. The optimal method of extraction was liquid-liquid extraction using 250 ul of ethyl acetate from 10 ul of whole blood in 50 ul of buffer at pH 10. The filter paper method of extraction was found to give erratic results. The calibration curve was linear over the concentration range of 10n/m1 to 0.5 ng/ml of hydrazinocurmin in whole human blood. Conclusion: The precision, accuracy, recovery and applicability were found to be adequate for pharmacokinetic studies in mice.

A method for quantitation of hepatitis C virus (HCV) RNA was developed based on competitive reverse transcription polymerase chain reaction (RT-PCR) using in vitro transcribed mutated thio-RNA as a competitor template. The thio-RNA is more resistant to RNAse and is stable over a year. This assay was compared with the commercially available Roche Amplicor HCV Monitor assay V 2.0 and real time PCR using SYBR green 1 dye method. A total of 18 pre-therapy serum samples from chronic hepatitis C cases were tested in parallel by the three assays. All samples could be quantitated using the in-house competitive RT-PCR and real time PCR and there was a significant correlation in the virus titer (P<0.05). However, 8 (44%) samples could not be quantified by Amplicor HCV Monitor assay, which has a lower detection range (10(2) to 10(5.5) copies/ml). The in-house method of competitive RT-PCR showed a detection range of 10(3) to 10(10) copies/ml. In the patients the mean viral titer was found to be (9.66+/-9.3)x10(6) copies/ml. Ten (55%) of the samples, assessed by the Amplicor HCV Monitor assay showed a mean viral titre of (1.13+/-0.75)x10(6) copies/ml, which was lower than the other two tests. The competitive PCR method and real time PCR could amplify all prevalent genotypes. This in-house quantitative competitive RT-PCR method is simple, cheap, reproducible and useful for estimation of HCV RNA load.

A cross sectional study of 115 patients admitted at the Department of Orthopedics, Kenyatta National Hospital, Nairobi, Kenya was carried out to determine the prevalence and antibiotic susceptibility of Staphylococcus aureus isolated from infected wounds. The prevalence of Staphylococcus aureus was 33.0 %. The drugs tested and their corresponding sensitivity was amoxycillin (13.2 %), co-amoxyclav (39.5 %), oxacillin (55.3 %), erythromycin (44.7 %), gentamicin (60.5 %), ciprofloxacin (62.2 %), minocycline (86.8 %), cefuroxime (57.9 %), and clidamycin (84.2 %). These results show the sensitivity profile of Staphylococcus aureus and can be used to choose suitable drugs in the management of wounds for hospitalized patients.

We employed macroscopic and ultrastructural techniques as well as intratracheal casting methods to investigate the pattern of development, categories, and arrangement of the air conduits in the chicken lung. The secondary bronchi included four medioventral (MVSB), 7-10 laterodorsal (LDSB), 1-3 lateroventral (LVSB), several sacobronchi, and 20-60 posterior secondary bronchi (POSB). The latter category has not been described before and is best discerned from the internal aspect of the mesobronchus. The secondary bronchi emerged directly from the mesobronchus, except for the sacobronchi, which sprouted from the air sacs. Parabronchi from the first MVSB coursed craniodorsally and inosculated their cognates from the first two LDSB. The parabronchi from the rest of the LDSB curved dorsomedially to join those from the rest of the MVSB at the dorsal border. Sprouting, migration, and anastomoses of the paleopulmonic parabronchi resulted in two groups of these air conduits; a cranial group oriented rostrocaudally and a dorsal group oriented dorsoventrally. The neopulmonic parabronchial network formed through profuse branching and anastomoses and occupied the ventrocaudal quarter of the lung. There were no differences in the number of secondary bronchi between the left and right lungs. Notably, a combination of several visualization techniques is requisite to adequately identify and enumerate all the categories of secondary bronchi present. The 3D arrangement of the air conduits ensures a sophisticated system, suitable for efficient gas exchange. Microsc. Res. Tech., 2008. (c) 2008 Wiley-Liss, Inc.

Aluda AT, Amugune BK, Abuga KO, Kamau FN. "Development and Validation of a Gas Chromatographic Method for Determination of Menthol in Cold-Cough Syrups." PJK. 2018;23(3):90-93. Abstract

Background
Common cold is the most common infection of the upper respiratory tract and cold-cough syrups are often prescribed. Although menthol is one of the common constituents of these syrups, quality checks on cold-cough syrups normally target the major active pharmaceutical ingredients without regard to menthol content.

Objective
To develop and validate a gas chromatography method for determination of menthol in cold-cough syrups.

Methods
A simple, rapid, robust, accurate and reliable Gas Chromatography method was developed and validated for the determination of menthol in cold-cough syrups that may also contain ambroxol, chlorpheniramine, guaifenesin, bromhexine and salbutamol.

Results
Optimized chromatographic conditions were: A ZB-WAXplus 60m ×0.25mm; 0.25μm fused silica capillary column. Oven temperature program of 110 0C (2 min), ramp 10 0C/min to 190 0C (2 min). Injector port temperature maintained at 240 0C. Injection volume of 1.0 μl split in the ratio of 50:1. Carrier gas as nitrogen at 1.0mL/min which also serves as make up gas (30 mL/min) in the flame ionization detector (260 0C). Other detector gases were hydrogen (30 mL/ min) and industrial air (300 mL/ min) and the diluent for samples and standards was grade chloroform.
From recovery studies, 97.56 to 102.97 % recovery was reported. Repeatability studies had a coefficient of variation of 0.55 while intermediate precision was 0.32. The method was linear over a range of 0.042 to 0.169 mg/mL with a coefficient of determination (R2) 0.9986.
Of the 21 samples analyzed, only 10 samples (47.6 %) complied with assay specifications of 90.0 to 110.0 % label claim for finished products according to the United States Pharmacopeia 2016.

Conclusion and recommendation
A gas chromatographic method was developed and validated for the determination of menthol in cold-cough syrups in Kenya. This method can be used together with a validated high-performance liquid chromatography method to assay cold-cough syrups that may also contain ambroxol, bromhexine, chlorpheniramine maleate, guaifenesin and salbutamol.
This method can be useful in routine analysis such as pre-registration studies as well as post market surveillance to curb substandard and counterfeit cold-cough syrups.

Okaru AO. Development and Validation of a Liquid Chromatographic method for the Analysis of Azithromycin.; 2013. Abstract

Azithromycin is a semi-synthetic macrolide antibiotic that is active against a number of Grampositive
and Gram-negative bacteria. Azithromycin is listed in the World Health Organization
and the Ministry of Health, Kenya essential drugs list. Therefore, the quality of azithromycin
products in the market is important because of its role in management of atypical infections.
Liquid chromatography is the method of choice for the analysis of azithromycin in bulk samples
and its formulations. However, the current published liquid chromatographic methods employ
extreme conditions of pH and temperature and also expensive columns for the analysis of
azithromycin.
In this study, a simple, isocratic, rapid, sensitive and robust reverse phase HPLC method was
developed for the analysis of azithromycin in tablets, suspensions and raw materials. The effect
of chromatographic factors including use of inorganic mobile phase buffer, pH, ion-pairing
agent, organic modifier and temperature were investigated during development. Waters XTerra®
C18 column having the dimensions of 250×4.6 mm and 5 μm particle size with mobile phase
containing a mixture of acetonitrile-0.1M KH2PO4 pH 6.5-0.1M tetrabutylammonium hydroxidewater
(25:15:1:59 % v/v/v/v) was employed to achieve separation of azithromycin and its related
substances. The pH of the buffer and ion pairing agent was brought to 6.5 using an equimolar
solution of 0.1M K2HPO4. The mobile phase was delivered at a flow rate of 1 ml/min and the
components were monitored at 215 nm while the column temperature was maintained at 43 °C.
The retention time of azithromycin was found to be about 8 min.
xviii
The proposed method was validated using ICH guidelines for the parameters of linearity,
recovery, precision, sensitivity and robustness. The method was found to be linear in the range
50-150 percent with the coefficient of determination (r2) being 0.997. The LOD and LOQ were
found to be 20 μg and 78 μg respectively. The method was found to exhibit good accuracy with
the percent recovery of azithromycin being 100.7 %. The coefficient of variation for the
repeatability and intermediate precision were within the limits prescribed by ICH.
The robustness ranges for the critical factors of pH, temperature and acetonitrile were
investigated with the aid of Statgraphics Centurion XVI. The robustness range for pH was 6-7
pH units, 22-28% v/v for acetonitrile and 41-45 °C for temperature. At 95% confidence interval,
p=0.05, acetonitrile had the biggest impact on the chromatographic parameters of the critical
peak pair of azithromycin and erythromycin A imino ether.
The degradation of azithromycin in 0.0005% v/v H2O2 was found to be second order (r2=0.994)
with a half life of 13 min. In 0.1M H3PO4 and 0.05M H3PO4, 90% of azithromycin decayed
within 10 min. In 0.025M H3PO4, the degradation was found to be first order with r2 being
0.9907 with a half life of 57.8 h.
The developed method was successfully applied in the analysis of azithromycin raw material and
twenty two commercial products obtained from retail pharmacies within the Central Business
District of the City of Nairobi. Thirteen of these products were tablets while nine were
suspensions of azithromycin. Five of the nine suspensions sampled were premixed suspensions
xix
while the rest were dry powders for reconstitution. Three tablet brands did not meet the United
States Pharmacopoeia (2012) specifications for assay (90.0-110.0% label claim) while three of
the premixed azithromycin suspensions did not meet the USP (2012) specifications. Similarly,
one of the four dry powders for reconstitution suspensions failed to comply with the assay
specifications.
The developed method is simple, robust, specific, accurate and stability indicating. It can
therefore be used by quality control laboratories in the routine analysis of azithromycin bulk
samples and formulations as well as in stability studies. The method can also be applied in post
market surveillance to monitor the quality of products in circulation and detect counterfeits.

Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. 81, 276-281]. The protein (lectin-trypsin complex) was found to be capable of stimulating differentiation of bloodstream trypanosomes in vitro. Using polyclonal antibodies to the complex, we screened a G. fuscipes fuscipes cDNA midgut expression library and identified a putative proteolytic lectin gene. The cDNA encodes a putative mature polypeptide with 274 amino acids (designated Glossina proteolytic lectin, Gpl). The deduced amino acid sequence includes a hydrophobic signal peptide and a highly conserved N-terminal sequence motif. The typical features of serine protease trypsin family of proteins found in the sequence include the His/Asp/Ser active site triad with the conserved residues surrounding it, three pairs of cysteine residues for disulfide bridges and an aspartate residue at the specificity pocket. Expression of the gene in a bacterial expression system yielded a protein (M(r) approximately 32,500). The recombinant protein (Gpl) bound d(+) glucosamine and agglutinated bloodstream-form trypanosomes and rabbit red blood cells. In addition, the protein was found to be capable of inducing transformation of bloodstream-form trypanosomes into procyclic forms in vitro. Antibodies raised against the recombinant protein showed cross-reactivity with the alpha subunit of the lectin-trypsin complex. These results support our earlier hypothesis that this molecule is involved in the establishment of trypanosome infections in tsetse flies.
