.O PROFGUMBELAWRENCE. "The B.Sc. Agricultural Engineering Course. Paper presented at the Agricultural Inter-University subject Meeting. September 5-10 Arusha, Tanzania.". In: Gabbay R. &Siddique A., ed., Good Governance Issues and Sustainable Development: The Indian Ocean Region (New Delhi: Vedams Books). ISCTRC; 1983. 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.

Abstract
HIV-specific cytotoxic T-lymphocytes (CTL) are believed to play a key part in the control of virus levels throughout HIV infection. An important goal of a potential prophylactic vaccine against HIV is therefore to elicit a strong CTL response which is broadly cross-reactive against a diverse range of HIV strains. We have detected HIV-specific CTL in two groups of highly-exposed but persistently seronegative female sex workers in Africa which show extensive cross-reactivity between different viral sequences. In a small group of women exposed to both HIV-1 and HIV-2 in Gambia, studied over 4 years, we have repeatedly detected HLA-B35-restricted CTL which exhibit cross-reactivity between the HIV-1 and HIV-2 sequences of the CTL epitopes. In women with particularly intense exposure to what are likely to be multiple clades of HIV-1 in Nairobi Kenya, we have detected CTL directed towards epitopes conserved between HIV-1 clades. In neither group is there any evidence that variation in CCR5 sequence or expression is responsible for their apparent resistance to HIV infection. However, in seropositive donors from Oxford infected with African strains of HIV-1, we have defined CTL responses which are specific for particular clades and have mapped some unique A clade CTL epitopes, together with others to highly-conserved regions of the virus. Further information about the extent of cross-reactive CTL immunity will be important for future vaccine design and evaluation.

This article reveals that the concept of education as a process of growth is a difficult one. Philosophers are, therefore, justified in being weary when pondering over its meaning, both in theory and practice. By way of conclusion, the article appreciates the complexities inherent in the growth theory of education, summarizing its major strength and weaknesses. Then it cautions educational planners and practitioners to be weary when, and if, they translate the theory into practice, so that they utilize the strengths inherent in the theory whilst paying attention to the dangers of its inherent weaknesses.

Abiodun, Adigun Ade; Odingo RS. "Basic Space Sciences In Africa.". 1983. AbstractWebsite

Through space applications, a number of social and economic programmes in education, communications, agro-climatology, weather forecasting and remote sensing are being realized within the African continent. Regional and international organizations and agencies such as the African Remote Sensing Council, the Pan-African Telecommunication Union and the United Nations system have been instrumental in making Africa conscious of the impact and implications of space science and technology on its peoples. The above notwithstanding, discernible interests in space research, to date, in Africa, have been limited to the work on the solar system and on interplanetary matters including satellite tracking, and to the joint African-Indian proposal for the establishment of an International Institute for Space Sciences and Electronics (INISSE) and the construction, in Kenya, of a Giant Equatorial Radio Telescope (GERT). During this “Transport and Communications Decade in Africa,” Africa's basic space research efforts would need to initially focus on the appropriateness, modification and adaptation of existing technologies for African conditions with a view to providing economic, reliable and functional services for the continent. These should include elements of electronics, communications, structural and tooling industries, and upper-atmosphere research. The experience of and collaborative work with India, Brazil and Argentina, as well as the roles of African scientists, are examined.

Burkitt Lymphoma (BL) is listed in the World Health Organization (WHO) classification of lymphoid tumours as an aggressive B-cell non-Hodgkin's lymphoma, characterized by a high degree of proliferation of the malignant cells and deregulation of the c-MYC gene. The main diagnostic challenge in BL is to distinguish it from diffuse large B-cell lymphoma (DLBCL). While in children BL and DLBCL types probably do not differ clinically, and the differential diagnosis between BL and DLBCL may theoretically appear clear-cut, in adults daily practice shows the existence of cases that have morphological features, immunophenotypic and cytogenetics intermediate between DLBCL and BL, and cannot be classified with certainty in these categories. Distinguishing between BL and DLBCL is critical, as the two diseases require different management. This review summarizes the current practical approach, including the use of a large panel of antibodies, and cytogenetic and molecular diagnostic techniques, to distinguish between BL, DLBCL and the provisional category of B-cell lymphoma, unclassificable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma, now listed in the updated WHO classification. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

J. O. Midiwo, A. Yenesew, B. F. Juma, S. Dereses, J. A. Ayoo, A. Aluoch and S. Guchu There are several described medicinal plants in Kenya from a flora of approximately 10,000 members. Strong cross-medical information from the 42 ethnic groups points to the high potential of some of these species. The Myrsinaceae are well established ethno-anthelmintics and anti-bacterials. They are harbingers of long alkyl side chain benzoquinones which clearly have a protective function from their histochemical disposition. The main benzoquinone in the sub-family Myrsinodae is embelin while for the Maesodae it is maesaquinone together with its 5-acetyl derivative; the distribution of these benzoquinones by their alkyl side chain length or the presence/absence of a 6-methyl group is in accord with morphological sub-family de-limitation. The benzoquinones showed anti-feedant, anti-microbial, phytotoxic, acaricidal, insecticidal and nematicidal activity. Many other benzoquinones of medium and minor concentration were also isolated and characterised. Some plants belonging to the Polygonaceae which are widely used as ethno-anthelmintics have been studied. The common anthelmintic anthraquinones were obtained from all five Rumex species while the naphthalenic acetogenin derivative, nepodin was more selectively distributed. The leaf of Polygonum senegalense is up to 17% surface exudate; about thirteen non polar flavonoid derivatives (chalcones, dihydrochalcones, flavanones and a flavone) have been isolated from it. From the internal aerial tissues of this plant, the major flavonoids were common flavonoids, quercetin, kaempferol, luteolin and their glycosides. The only unique compound isolated from this plant was 2prime-glucosyl-6prime-hydroxy-4prime-methoxydihydrochalcone whose aglycone, uvangolatin is part of the exudate mixture. Other leaf exudate plants studied include the stomach-ache medicine, Psiadia punctulata (Compositae) from which novel methylated flavonoids, kaurene and trachyloban diterpenes have been found

Abstract
Hemorrhage is the main cause of Maternal Mortality (MM) (27%) followed by hypertensive disorders and sepsis (12%). Septic abortion is considered an intermediate risk factor for the development of Massive Obstetric Hemorrhage (MOH). The algorithm for the management of postpartum hemorrhage due to uterine atony that includes systematic pelvic devascularization has been described, but this management is really planned for resolution of the pregnancy after the 20th week of gestation, since an HMO due to abortion is un usual. We present the case of a 21-year-old patient who self-medicates a prostaglandin analog at 2 months of pregnancy, achieving only a threat of abortion, goes to the emergency room 3 months later with a diagnosis of septic shock, USG and MRI are performed with altered results, only of hepatomegaly, delayed abortion of 8 weeks of evolution and gestational trophoblastic disease. Emergency MVA was performed due to profuse bleeding, placement of a Bakri balloon and clamping of the uterine arteries without results, for which an emergency exploratory laparotomy (LAPE) was performed with ligation of the anterior trunk of the internal iliac artery, being a successful procedure, without the need for Obstetric Hysterectomy (HO). The patient is managed in intensive care and in the end the diagnosis of TSG is ruled out. Bilateral Hypogastric Artery Ligation (BHAL) in the case of Massive Obstetric Hemorrhage (MOH) secondary to delivery or cesarean section is commonly used, however it is not a technique to report when bleeding is secondary to abortion. In these cases, it is also a viable, successful, fertility-preserving surgical procedure, and an alternative to Obstetric Hysterectomy (OH) when other less invasive methods such as uterine artery clamping or Bakri balloon have failed.

Aosa EA, Machuki V, Letting N. "Board Diversity and Performance of Companies Listed in Nairobi Stock Exchange." International Journal of Humanities and Social Science. 2012;Vol. 2 No. 11(June). Abstract

This study examined the relationship between Board diversity and financial performance of firms listed in the Nairobi Stock Exchange. Data on Boards’ age, gender, educational qualifications, study specialization, and board specialization as well as the companies’ financial performance were obtained from 40 companies using a structured questionnaire. Using the Ordinary Least Squares (OLS) regression, the results show that there is a weak positive association between board diversity and financial performance. Overall, the results indicate a statistically not significant effect of board diversity on financial performance except for the independent effect of board study specialization on dividend yield. The results partially concur with agency and resource dependency theories of corporate governance as well as similar empirical studies. Ensuing implications for theory, policy and practice as well as methodology are also discussed.

HIV-exposed uninfected (HEU) infants have higher infectious disease morbidity and mortality than unexposed infants. We determined the incidence and risk factors for pneumonia, a leading cause of infant mortality worldwide, in a cohort of HEU infants. Identifying predictors of pneumonia among HEU infants may enable early identification of those at highest risk.

The superior cerebellar artery is the most consistent branch of the basilar artery and arises near the bifurcation of the basilar artery. A bilateral origin of the superior cerebellar arteries from the posterior cerebral arteries has been rarely reported in the literature. Reporting variations in brain vessels is important for neurosurgeons to safely and confidently treat pathologies in this region. We report on a specimen with a bilateral origin to the superior cerebellar artery from the posterior cerebral artery and discuss the embryogenesis of this rare variation.

Ayuke FO. Biodiversity of soil macrofauna functional groups and their effects on soil structure in West and East African cropping systems, as related to organic resource management, crop rotation and tillage. Wageningen, The Netherlands: Wageningen University; 2010. Abstract

Soil macrofauna, especially earthworms and termites are important components of the soil ecosystem and, as ecosystem engineers, they influence formation and maintenance of the soil structure and regulate soil processes. Despite advances made in understanding the links between soil macrofauna and agricultural productivity, this component of biodiversity is still very much a “black box”. In this thesis, I proposed to link soil biodiversity to soil functioning through the diversity of the soil structures produced by ‘ecosystem engineers’ like earthworms and termites, i.e. organisms, which physically modify and create habitats for other soil organisms and plant roots. This study aimed at providing an understanding of the link between soil macrofauna and crop management practices on soil aggregation and soil organic matter (SOM) dynamics as this is key to the improvement and the management of infertile or degrading soils.
The methodological approach used in this study involved assessment of:
1. How agricultural management affects earthworm and termite diversity across sub-humid to semi-arid tropical zones.
2. The influence of soil macrofauna on soil aggregation and SOM dynamics in agro-ecosystems of sub-Saharan Africa as influenced by management practices.
3. How management practices (e.g. tillage and use of organic inputs) influence macrofauna-induced biogenic structures in East and West African soils.
4. Disclosing farmers’ knowledge and perception on the roles of termites in Western Kenya.

In chapter 2, I examined how agricultural management affects earthworm and termite diversity across sub-humid to semi-arid tropical zones. This study, conducted in 12 long-term agricultural field trials of Eastern and Western Africa, provides new insights on diversity of earthworms and termites in SSA, since it is the first time that a study like this is done on this scale. In each trial, treatments with high and low soil organic C were chosen to represent contrasts in long-term soil management effects, including tillage intensity, organic matter and nutrient management and crop rotations. High soil C was considered to reflect relatively favorable conditions, and low soil C less favourable conditions for soil macrofauna. For each trial, a fallow representing a relatively undisturbed reference was also sampled.
I have shown that earthworm and termite diversity and abundance were low in fallow, high-C and low-C agricultural treatments in 12 long-term trial fields across the sub-humid to semi-arid tropical zones in Eastern and Western Africa. This is in contrast to most typical native or undisturbed forest ecosystems of the tropical zones. Environmental variables contributed 42% and 25% of variation observed in earthworm and termite taxonomic abundance, respectively. Earthworm and termite taxa were less abundant in the relatively cooler, wetter and more clayey sites characteristic of Eastern Africa, compared to the warmer, drier and more sandy sites in West Africa. Continuous crop production has significant negative effects on earthworm-, but little effect on termite diversity, as compared to long-term fallow, and agricultural management resulting in high soil C increases earthworm and termite diversity as compared to low-C soil. I conclude that fewer species of earthworms and termites are favored under agricultural management that leads to lower soil C. Results indicate that soil disturbance that goes with continuous crop production is more detrimental to earthworms than to termites as compared to fallow.

In chapter 3, a broad regional study was conducted to examine how management intensity affects soil macrofauna, and how macrofauna in turn influence soil aggregation in agro-ecosystems of sub-Saharan Africa.
My study has shown that macrofauna, especially earthworms, and to a smaller extent termites, are important drivers of stable soil aggregation, in conjunction with climate, soil organic C content and soil texture in sub-Saharan agroecosystems. However, the beneficial impact of earthworms and termites on soil aggregation is reduced with increasing management intensity and associated soil disturbance due to cultivation. I suggest that this knowledge is important in designing agricultural management systems aimed at increasing long-term soil fertility in sub-Saharan Africa.

In chapter 4, a long-term trial at Kabete, Kenya was selected to examine in detail the interactive effects of organic and inorganic fertilizerson soil macrofauna diversity and soil aggregation and SOM dynamics in arable cropping systems. Differently managed arable systems were compared to a long-term green fallow system representing a relatively undisturbed reference.
Application of manure in combination with fertilizer significantly improved aggregate stability and C and N stabilization in arable soil. Furthermore, manure-fertilizer application enhanced earthworm diversity and biomass. Significant correlations between the amount and C and N contents of aggregate fractions and whole soil C and N were observed with earthworm parameters (Shannon diversity index, abundance and biomass), but not with termite parameters. Factor and regression analyses showed that earthworms had a profound effect on aggregation, C and N stabilization in whole soil and in aggregate fractions, whereas contributions of termites were limited. Therefore, my results indicate that long-term application of manure in combination with fertilizer result in higher earthworm Shannon diversity and biomass, which leads to improved soil aggregation and enhanced C and N stabilization within this more stable soil structure. These practices therefore result in the dual benefits of improving soil physical and chemical properties. In contrast, no significant improvements in soil aggregation and C and N stabilization were found when organic inputs were applied in the form of maize stover as compared to the no-input control, irrespective of fertilizer addition. Under the conditions studied, earthworms were more important drivers of aggregate stability and C and N stabilization in aggregate fractions, but termites less so.

In chapter 5, a micromorphological approach was used to describe and quantify macrofauna-induced biogenic structures in undisturbed soil samples (i.e. thin sections) from long-term field experiments in East and West Africa. Management systems differing in tillage intensity and with or without organic amendments (manure/crop residue) were compared.
My study has shown the soil management practices tillage type and addition of organic inputs influence soil fauna activities with a significant impact on soil structure and hence soil physical properties. Among the management practices assessed across two agroecological zones, fallowing, conservation tillage plus residue application (in East Africa) and hand-hoeing plus manure (in West Africa) enhanced biogenic soil structure formation, resulting in a well developed soil structure and a continuous pore system through many faunal channels. By contrast, intensive tillage and absence of organic inputs resulted in soil with less biogenic soil structural features and was, therefore, prone to slaking.

Chapter 6 describes farmers’ knowledge on the occurrence and behavior of termites, their perception of the importance of termites in their cropping systems and the management of termite activities in their farm fields in Nyabeda, Western Kenya. Being the main actors in environmental conservation or degradation, farmers’ knowledge and perception can enrich scientific understanding of the ecology and sustainable management of termites under different agroecological conditions.
My research has shown that farmers in Nyabeda were aware of the existence of termites, their activities and nesting habits and had local names for termites that they frequently encountered. Geographic location explained 23% of the variance in farmers’ perception and management of termites, whereas socio-economic variables explained only 5%. Ninety percent of the farmers perceived termites as pests and maize was rated as the most susceptible crop to termite attack, especially during the flowering/tasseling stage and in wet periods. More than 88% of the farmers used control measures against termites, further indicating a lack of awareness or appreciation of the beneficial effects often ascribed to termites with respect to soil properties in crop production. There is an urgent need for more research to assess the trade-offs between positive and negative impacts of termites on crop yields, as well as to get an understanding of the effects of different termite control strategies used by farmers on agroecosystem functions.

In: Am J Trop Med Hyg. 2007 Dec;77(6 Suppl):88-98. Taylor & Francis; 2008. Abstract
Human co-infection with Plasmodium falciparum and helminths is ubiquitous throughout Africa, although its public health significance remains a topic for which there are many unknowns. In this review, we adopted an empirical approach to studying the geography and epidemiology of co-infection and associations between patterns of co-infection and hemoglobin in different age groups. Analysis highlights the extensive geographic overlap between P. falciparum and the major human helminth infections in Africa, with the population at coincident risk of infection greatest for hookworm. Age infection profiles indicate that school-age children are at the highest risk of co-infection, and re-analysis of existing data suggests that co-infection with P. falciparum and hookworm has an additive impact on hemoglobin, exacerbating anemia-related malarial disease burden. We suggest that both school-age children and pregnant women–groups which have the highest risk of anemia–would benefit from an integrated approach to malaria and helminth control.

The microbiological quality of ground water (boreholes) and domestic tanks in five locations of Kikuyu Division, Kiambu District, was determined. Two boreholes and twelve domestic tanks were sampled from each location. Seven (70%) out of 10 boreholes were contaminated with faecal coliforms. Total bacterial counts ranged from 1 to 6280 per ml of water while the coliform counts ranged from 0 to 161. Out of 70 water samples screened for faecal coliforms, 63 (90%) were positive. Faecal Streptococci were isolated in 71% of the samples.

This study was conducted to evaluate the control of trypanosomosis in camels in Turkana district of Kenya using participatory approaches. Lapur division of the district was conveniently selected as the study area considering logistics and security concerns. Four main animal camps (adakars) formed the study units. Key informants from each adakar were selected for participatory research processes. Participatory mapping, semi-structured interviews, pair-wise comparisons and matrix scoring were the participatory methods employed. Five camel diseases in order of their importance, were identified, namely, camel trypanososmosis, tick infestation, non-specific diarrhoea, mange and harmorrhagic septicaemia. Twelve groups of the lay key informants agreed well on the presenting signs of theses diseases. Although trypanocides were considered by the informants to be reasonably available, the most preferred method for the control of camel trypanosomosis was the use of indigenous remedies. These indigenous remedies included the oral administration to sick camels with variety of herbs mixed with soups from goat, wildcat, bird or donkey meat. The results from this study revealed that camel trypanosomosis is an important disease in Turkana district. The prices of the available modern trypanocides in the management of camel trypanosomosis appeared to hamper the effective control of the disease. However, the efficacy of the widely used indigenous remedies remains undetermined.
Baghurst PA, Nichol LW. "The binding of organic phosphates to human methaemoglobin A. Perturbation of the polymerization of proteins by effectors." Biochim. Biophys. Acta. 1975;412(1):168-80. Abstract

Theory is presented relating to the binding of an effector to two states of a protein acceptor coexisting in equilibrium. The problem is treated in terms of the four possible cases which specify relations between numbers of binding sites and intrinsic binding constants relevant to the acceptor states. It is shown that a distinction between these cases may be possible on the basis of the form of a plot of unbound effector concentration versus the constituent equilibrium coefficient which may be calculated from the sedimentation coefficient of the protein constituent. Particularly noteworthy in this respect is the finding that a turning point may exist in this plot for defined conditions with systems in which binding sites are not conserved (and binding affinities are altered) on polymer formation. The latter type of system is exemplified by studies on methaemoglobin A in 0.25 M sodium acetate, pH 5.4. In the absence of added organic phosphate effectors, a dimer-tetramer equilibrium operates governed by an association constant of 4.15 +/- 0.06 X 10(3) 1/mol, determined from sedimentation equilibrium results. Correlation of sedimentation velocity and equilibrium results shows that addition of adenosine 5'-triphosphate (ATP) results in its binding to one site on each of the dimeric (alpha beta) and tetrameric (alpha beta)2 species with intrinsic binding constants 1.03-10(3)-1.20-10(3) and 1.1-10(4)-2.1-10(4) 1/mol, respectively. It is also shown that 2,3-diphosphoglycerate perturbs the dimer-tetramer equilibrium in a similar way to ATP.

The 'WISE-UP to climate'project aims to demonstrate the value of natural infrastructure as a
'nature-based solution'for climate change adaptation and sustainable development. Within
the Tana River Basin, both natural and built infrastructure provide livelihood benefits for
people. Understanding the interrelationships between the two types of infrastructure is a
prerequisite for sustainable water resources development and management. This is
particularly true as pressures on water resources intensify and the impacts of climate change
increase. This report provides an overview of the biophysical characteristics, ecosystem
services and links to livelihoods within the basin.

Less than 20% of Kenya's population is connected to the grid. Only 5% of the country's rural population, which accounts for over 70% of the total population enjoys electricity connectivity. To compensate for this deficiency in rural areas, kerosene has been the preferred choice for lighting. Kerosene is used in approximately 92% of all households. Off-grid lighting products such as LED lights are poised to play a pivotal role in the transformation of the lighting scenario in the rural areas of the developing world. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Kenya is a country of marked environmental and ethnic diversity. A study of osteogenic sarcoma occurring in Kenya from 1968 to 1978 revealed 251 cases, representing between 89% and 100% of the predicted number. Variations in age, sex and anatomical location were within classical limits. However, the incidence of osteogenic sarcoma amongst the Central Bantu was significantly higher than predicted (P less than 0.0001), whilst the incidence among the Western Bantu was significantly lower (P less than 0.002), despite their similar ethnic origins. Two geographically dissimilar areas likewise exhibited significant differences in incidence. The Eastern province showed a higher incidence (P less than 0.02), whereas the Nyanza Province (P less than 0.001) and the adjacent Western Province (P less than 0.005) showed a lower than predicted incidence. These observations suggest that in Kenya a geomedical variable affects the incidence of osteogenic sarcoma and that genetic variation has no effect on incidence.

OBJECTIVE: To determine platelet abnormalities in patients with menigococcal meningitis. DESIGN: Case control study. SUBJECTS: Fifty seven cases of mennigococcal meningitis based on a cerebrospinal fluid gram stain for gram negative diplococcus or positive culture were recruited. Fifty-seven controls matched for age and sex were also recruited. The following platelet functions tests were performed; platelet counts, platelet adhesiveness, platelet aggregation and clot retraction. RESULTS: Fifty seven patients (41 males and 16 females) with meningococcal meningitis were studied. Their mean age was 25.5 +/- 8.32 years with a range of 15 to 45 years. Five patients had purpura, four peripheral gangrene, eight conjunctival haemorrhages and one was in shock. There was a statistical significant difference in the platelet aggregation and clot retraction between the patients and controls at p-values of 0.0001 and 0.0002 respectively. There was no significant difference in the platelet count and adhesiveness between the patients and the controls at a p-value of 0.203 and 0.22 respectively. No association was found between the platelet functions and the clinical presentations. CONCLUSION: Patients with meningococcal meningitis have abnormalities in the platelet functions mainly in aggregation and adhesiveness.

The hemodynamic responses to exercise have been studied to a great extent over the past decades, and an exaggerated blood pressure response during an acute exercise bout has been considered as an indicator of cardiovascular risk. Obesity is a major factor influencing the blood pressure response to exercise since evidence indicates that the arterial pressure response to exercise is exacerbated in obese compared with lean adults. Signs of augmented responses (such as an exaggerated blood pressure response) to physical exertion appear early in life (from the prepubertal years) in obese individuals. Understanding the mechanisms that drive the altered hemodynamic responses during exercise in obese individuals and prevent the progression to hypertension is vitally important. This paper focuses on the evidence linking obesity with alterations of the autonomic nervous system and discusses the potential mechanisms and consequences of the altered sympathetic nervous system behavior in obese individuals at rest and during exercise. Furthermore, this paper presents the alterations in the reflex regulatory mechanisms (&\#8220;exercise pressor reflex&\#8221; and baroreflex) in obese children and adults and addresses the effects of training on obesity-related disturbances.

Dossaji SF, Mabry TJ, Bell EA. "Biflavonoids of the Cycadales." Biochemical Systematics and Ecology. 1975;2:171-175. Abstract

Biflavanoid patterns of leaves of 82 species of the order Cycadales comprising 3 families and 10
genera have been determined. The biflavanoidswere Identified byTLC, UV, NMR and MS studies. Pattern differences between species, when detected, involve the position or degree of methylation of the base compounds. On the other hand, differences in the biflavanoid patterns at the generic and family levels were sufficient to support taxonomic relationships. Thus, the absence of hinokiflavone and its derivatives clearly distinguish the Zamiaceae from the Cycadaceae and Stangeriaceae. The complete absence of biflavanoids in the latter family suggests an advanced evolutionary condition, but morphologically, this family has the most fern-like characters, and therefore has been considered by previous workers to be the most primitive of the cycads.

Dossaji SF, Bell EA, Wallace JW. "Biflavones of Dioon." Phytochemistry. 1973;12:371-373. Abstract

Abstract—Seven biflavones, amentoflavone, bilobetin, sequoiaflavone, ginkgetin, sciadopitysin, 7,4',7',4"-
tetra-O-methylamentoflavone, and diooflavone (amentoflavone hexamethyl ether), were identified from
extracts of the cycad genus Dioon. The biflavones were identified by direct comparison with authentic
samples using m.m.p., co-chromatography in 3 solvents, and NMR studies of the acetates. This is the first
time amentoflavone hexamethyl ether has been identified as a natural product. After surveying numerous
species of the Cycadales, no evidence could be obtained for the occurrence of biflavones glycosides or of biflavones base upon any other nucleus than apeginin.

"Biopiracy versus One-World Medicine–From colonial relicts to global collaborative concepts." Phytomedicine. 2019;53:319-331. Abstract

Background
Practices of biopiracy to use genetic resources and indigenous knowledge by Western companies without benefit-sharing of those, who generated the traditional knowledge, can be understood as form of neocolonialism.
Hypothesis
The One-World Medicine concept attempts to merge the best of traditional medicine from developing countries and conventional Western medicine for the sake of patients around the globe.
Study design
Based on literature searches in several databases, a concept paper has been written. Legislative initiatives of the United Nations culminated in the Nagoya protocol aim to protect traditional knowledge and regulate benefit-sharing with indigenous communities. The European community adopted the Nagoya protocol, and the corresponding regulations will be implemented into national legislation among the member states. Despite pleasing progress, infrastructural problems of …

Mike English and colleagues argue that as efforts are made towards achieving universal health coverage it is also important to build capacity to develop regionally relevant evidence to improve healthcare.

Achieving universal coverage that supports high-quality care will require that health systems are designed to integrate the delivery of health services with the generation of new knowledge about the effectiveness of these services.
System strengthening and research will need to be better integrated to achieve this in low- and middle-income countries (LMIC) so that changes in coverage, quality, and impact are measured, costs are contained, and health systems are responsive to users’ needs and concerns.
In high-income countries, learning health systems (LHS) are emerging to meet similar needs. The LHS vision aspires to engage policy makers, researchers, service providers, and patients in learning that uses and strengthens routinely collected data to conduct pragmatic, contextually appropriate research, promote rapid adoption of findings to improve quality and outcomes, and promote continuous learning.
Although there are significant challenges, we should begin to develop LHS in LMIC for their immediate and longer term benefits and to avoid having to retrofit health systems with the capability to promote learning at a later date and even greater cost.
A global coalition on how to build LHS effectively that shares accumulating learning could enable such a strategy.

ABSTRACT: Several strategies are employed in management of insect pests. Among these, chemical control is a priority to most farming communities where pest incidences occur while other existing options such as biological control are rarely considered. In coffee farming agro ecosystems, there are indigenous biological control agents such as the predacious phytoseiid mites, Euseius kenyae (Swirski and Ragusa) that have the potential to manage secondary pests like coffee thrips, Diarthrothrips coffeae Williams. This study was conducted to assess the population dynamics of E. kenyae and D. coffeae as well as theirinteractions under coffee agro ecosystems where various soil fertilizer sources and selective insecticides were applied as treatments. The populations of both E. kenyae and D. coffeae fluctuated during the three years study period. The E. kenyae suppressed the population of D. coffeae under various treated coffee blocks. There was negative correlation between E. kenyae and D. coffeae in year 2006 and 2008 where the increasing population of E. kenyae decreased that of D. coffeae. In year 2007, positive correlation between E. kenyae and D. coffeae was observed in some of the treatments where increased population of D. coffeae caused an increased population of E. kenyae. Euseius kenyae managed to contain the D. coffeae population to below economical injury levels (1-2 thrips per leaf) during the three years under the various coffee agro ecosystems. The use of chlorpyrifos never affected E. kenyae. Their survival and increased in number under chlorpyrifos treated coffee blocks indicated the development of resistance by the population of E. kenyae, hence the possibility of using them as a component in an Integrated Pest Management strategy in coffee.

Faktorovich EG, Steinberg RH, Yasumura D, Matthes MT, LaVail MM. "Basic fibroblast growth factor and local injury protect photoreceptors from light damage in the rat." The Journal of neuroscience: the official journal of the Society for Neuroscience. 1992;12:3554-3567. Abstract

Injection of basic fibroblast growth factor (bFGF) into the eye, intravitreally or subretinally, delays photoreceptor degeneration in inherited retinal dystrophy in the rat, as does local injury to the retina (Faktorovich et al., 1990). To determine whether this heparin-binding peptide or local injury is effective in any other form of photoreceptor degeneration, we examined their protective roles in light damage. Albino rats of the F344 strain were exposed to 1 or 2 weeks of constant fluorescent light (115-200 footcandles), either with or without 1 microliter of bFGF solution (1150 ng/microliters in PBS) injected intravitreally or subretinally 2 d before the start of light exposure. Uninjected and intravitreally PBS-injected controls showed the loss of a majority of photoreceptor nuclei and the loss of most inner and outer segments after 1 week of light exposure, while intravitreal injection of bFGF resulted in significant photoreceptor rescue. The outer nuclear layer in bFGF-injected eyes was two to three times thicker than in controls, and the inner and outer segments showed a much greater degree of integrity. Following recovery in cyclic light for 10 d after 1 week of constant light exposure, bFGF-injected eyes showed much greater regeneration of photoreceptor inner and outer segments than did the controls. bFGF also increased the incidence of presumptive macrophages, located predominantly in the inner retina, but the evidence suggests they are not directly involved in photoreceptor rescue. Subretinal injection of bFGF resulted in photoreceptor rescue throughout most of the superior hemisphere in which the injection was made, with rescue extending into the inferior hemisphere in many of the eyes. Remarkably, the insertion of a dry needle or injection of PBS into the subretinal space also resulted in widespread photoreceptor rescue, extending through 70% or more of the superior hemisphere, and sometimes into the inferior hemispheres. This implicates the release and widespread diffusion of some endogenous survival-promoting factor from the site of injury in the retina. Our findings indicate that the photoreceptor rescue activity of bFGF is not restricted to inherited retinal dystrophy in the rat, and that light damage is an excellent model for studying the cellular site(s), kinetics, and molecular mechanisms of both the normal function of bFGF and its survival-promoting activity. Moreover, the injury-related rescue suggests that survival-promoting factors are readily available to provide a protective role in case of injury to the retina, presumably comparable to those that mediate the "conditioning lesion" effect in other neuronal systems.

Department of Paediatrics and Child Health, College of Health Sciences, University of Nairobi, P.O. Box 19676, Nairobi, Kenya. BACKGROUND: There is laboratory evidence of altered immune function in children with malaria. Bacterial infections have been documented to complicate severe forms of malaria. However, it remains unclear whether such infections are attributable to the malaria, other risk factors, or are coincidental. OBJECTIVE: To determine the prevalence of bacteraemia and urinary tract infections (UTI) in febrile hospitalised children with and without malaria. DESIGN: A cross-sectional survey. SETTING: General paediatric wards, Kenyatta National Hospital, Nairobi. SUBJECTS: Children aged between three months and 12 years admitted with an acute febrile illness, with no obvious focus of bacterial infection. MATERIALS AND METHODS: Using a standardised questionnaire, information on socio-demography, symptomatology, and nutritional status was obtained. Malaria slides, blood and urine cultures were performed on each child. RESULTS: Malaria parasitaemia was present in 158 (60%) of 264 children presenting with acute febrile illness with no obvious focus of bacterial infection. Bacteria were isolated from blood and/or urine of 62 (23%) of all enrolled children. Bacteraemia was prevalent among 11.4% of 158 children with malaria and among 13.2% of 106 without malaria. Gram-positive organisms comprised 28.1% of blood isolates, gram-negative 62.5%, and atypical bacteria 9.4%. UTI was prevalent among 13.3% of 158 children with malaria and 16.0% of 106 children without malaria. Gram-positive organisms comprised 18.4%, gram-negative 78.9%, and atypical bacteria 2.6% of the urine isolates. Presence of malaria parasitaemia was not associated with an increased risk of bacteraemia (OR 0.9, 95% CI [0.4-0.7], or UTI (OR 0.8 95% CI [0.4-1.6] in this study population. CONCLUSION: Among children hospitalised in Nairobi with fever and no obvious bacterial infective focus, there should be a high index of suspicion for malaria, followed by bacteraemia and UTI. Malaria parasitaemia does not appear to be associated with increased risk of bacterial co-infection. PMID: 15080516 [PubMed - indexed for MEDLINE]

Fredrick O. "THE BULL AND BEAR MARKET AT THE NAIROBI SECURITIES EXCHANGE." Aim Journal of Business . 2008. Abstract

This research sought to establish the existence of the bull and bear market at the Nairobi Securities Exchange. The bull market is experienced when the prices of securities are in an upward trend while the Bear market is experienced when the prices of securities are in a downward trend. Bull and bear market can be traced back to the time of Charles Dow when he made analysis of trends in the stock market. The current and potential investors do not have any form of reference when making investment decisions, they will therefore benefit from this research since they will confirm which months are prone to the bull and bear markets and therefore not dispose their stocks in panic and also know the best time to purchase shares respectively. The Government will also benefit from it since it will be able to create a conducive environment for investment in the stock exchange and also for taxation purposes. It will also be useful to the Capital Markets Authority which is the main regulator of the Nairobi Securities Exchange since they will establish the genuine bull and bear market. The research was entirely based on secondary data from stocks of the year 2006. The research design was historical since it was dealing with issues that had occurred. Some fifteen out of the fifty two equities of companies trading in the Nairobi Securities Exchange were analyzed. Stratified and purposive samplings were used to select the fifteen companies. The data was analysed using percentages, mean, standard deviation and correlation coefficients. The findings confirmed that all the sampled stocks experienced both the bull and bear market. January, February and March were the months when most stocks experienced the bear market while August to November were the months when the majority of stocks experienced bull market. The study recommends the licensing of more stock brokers by CMA and also a further research into the role of stock brokers in influencing stock prices in the secondary market.

OBJECTIVE: We compared 12-month continuation rates, menstrual bleeding patterns and other aspects of acceptability between users of Cyclofem and users of Depo-Provera. METHODS: The life-table method was used to calculate quarterly continuation rates. In all, 360 Kenyan women were randomly assigned to one of the two contraceptives. User-satisfaction questionnaires were administered at 6 and 12 months or at discontinuation, whichever occurred first. RESULTS: The 1-year continuation rate was 75.4% for Depo-Provera users versus 56.5% for Cyclofem users (p<.001). Main reasons for discontinuation included difficulty making clinic visits (45.1% for Cyclofem vs. 40% for Depo-Provera), menstrual changes (14.1% vs. 12.5%) and nonmenstrual problems (15.5% vs. 12.5%). None of the Depo-Provera users and 8.5% of the Cyclofem users claimed frequency of visits as the main reason for discontinuation. In all, 70.6% of the Depo-Provera users were amenorrheic after 12 months, as were 20.8% of the Cyclofem users. CONCLUSIONS: The 1-year continuation rate was higher for Depo-Provera than for Cyclofem. There was no important difference in discontinuation rates because of menstrual problems; the difference mainly reflected the frequency of visits required.

There have been very few studies in Kenya on aerosols despite the global demand on aerosol ground studies in the perspective of climate and the human well being. Therefore, atmospheric aerosol studies became the basis of the work covered in this thesis which describes aerosol studies in Kenya and development of an energy dispersive X-ray fluorescence spectrometer (EDXRF). Atmospheric aerosols are composed of both the particulate and gas phases and they contain chemical compounds and elememts that are harmful to human health. Their particle size range is related to sources and this determines their impact in the ambient aatmosphere. Anthropogenic activities mainly contribute fine particles mass (PM 2.5) and natural proceses contribute both fine and course (PM (10-2.5)) particle masses. PM10 (PM 2.5 + PM (10-2.5)) are inhalable into the human respiratory system and the fine particles have a marked impact on climate. PM10 particles are efficient in transporting micronutrients between ecosystems, soiling and destroying buildings. Any policies meant to protect the environment by controlling atmospheric aerosol particles will need back up knowledge on particle sources and their physical and chemical characteristics. The five sampling campaigns covered under this study were conducted in Nairobi city, Meru and Nanyuki towns and on the slopes of Mount Kenya at about 2000m and 4000 m above the sea level. The multi-elemental analyzing capacity of EDXRF and statistical treatment of data are indispensable tools in aerosol source identification. These techniques were used in all the published results. The results revealed the dominance of local and regional biomass burning and local soil dust emissions. Traffic emissions were more pronounced in urban centers, with high concentrations of Br, Pb and Mn in Nairobi but with minor contribution at the remote sites on Mount Kenya. Marine influence was seen superimposed in the soil dust emissions and agricultural activities were also identied through elevated concentrations of Ca, Cl, K and S in the same source. Nairobi turned out to be a more polluted city in comparison to Dar es Salaam, Gaborone and Khartoum in Africa. The developed EDXRF spectrometer will play a major role in environmental studies in Kenya. Longterm measurements of Kenyan aerosols are recommended to better understand the total picture of aerosol particles including seasonal variation.

The human body louse, Pediculus humanus, showed eighteen midgut proteins ranging between 12 and 117 kDa, when analysed by SDS-PAGE electrophoresis. Seven of them (12 kDa, 17 kDa, 29 kDa, 35 kDa, 40 kDa, 55 kDa and 97 kDa) were major bands based on their intensity of staining. The immunization of rabbits with a midgut extract elicited the production of protective polyclonal antibodies. These antibodies reacted strongly with all major midgut proteins as well as with 63 kDa and 117 kDa proteins when tested by the Western blot technique. The analysis of the proteins revealed that the 12 kDa, 25 kDa, 29 kDa, 35 kDa, 45 kDa, 87 kDa and 97 kDa proteins are glycosylated and none of them contained a lipid moiety. By electroelution, the proteins of 35 kDa and 63 kDa were purified. On trypsinization, the proteins of 35 kDa and 63 kDa produced four major fragments (F1, F2, F3, and F4) when resolved on a 18% SDS-PAGE. The F1 fragment of the 35 kDa protein reacted with the polyclonal antibodies by the immunoblot technique.
