Lore, TA, Imungi JK, Mubuu K.  2013.  A Framing Analysis of Newspaper Coverage of Genetically Modified Crops in Kenya. Abstract

There was much public debate in Kenya about genetically modified (GM) crops when the national Biosafety Bill went through the parliamentary process toward enactment into law. This study analyzed how GM crops were framed in three mainstream Kenyan newspapers—the Daily Nation, The Standard, and Taifa Leo—during the period. The agriculture frame was predominant in the Daily Nation and The Standard, while the safety and regulation frames dominated coverage in Taifa Leo. Only 34.7% of articles were neutral in tone. Scientists and government officials, who generally spoke in favor of GM crops, were the most frequently quoted sources. Recommendations to improve the quality of coverage include training of journalists to ensure objective and balanced reporting.

Kunyanga, CN, Imungi JK, Okoth MW, Biesalski HK.  2012.  Total phenolic content, antioxidant and antidiabetic properties of methanolic extract of raw and traditionally processed Kenyan indigenous food ingredients. Abstract

Certain indigenous foods commonly consumed by Kenyan vulnerable groups (the malnourished; children under 5 years of age; pregnant and lactating women; malnourished adults in cases of vitamin or mineral deficiencies, TB, diabetes, cancer, AIDS; refugees; orphans the elderly and the disabled) are not yet evaluated for phenolic content and health relevant functionality. The present study was therefore designed to analyze the phenolic content, antioxidant and antidiabetic properties of methanolic extract of raw and traditionally processed food ingredients. The total phenolic contents of the cereals, legumes, oil seeds and vegetables were ranged from 0.41 to 3.00 g/100 g DM. Amaranth grain (Amaranthus cruentus) and drumstick leaves (Moringa oleifera) exhibited significantly higher phenolic content than the other samples. The methanolic extract of the investigated samples showed promising levels of DPPH radical scavenging activity (81–89%); ferric reducing/antioxidant power (FRAP, 44–744 mmolL−1 Fe[II]/g extract DM); α-amylase (10–45%) and α-glucosidase (13–80%) inhibition activities. The food ingredients with high phenolic content exhibited relatively higher antioxidant and antidiabetic activities. The results indicate that soaking + cooking is the mild processing method to preserve the phenolic compounds and their health relevant functionality in the presently investigated cereal, legume and oil grains, while cooking is suitable treatment for vegetables.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

Onyango, CM;, Harbinson J;, Shibairo SI;, Imungi JK.  2011.  Effect of organic and in organic fertilisers on yield and quality of amaranth in sub-Saharan Africa. Abstract

This study was designed to evaluate the influence of manure and mineral fertilization on yield, Kjeldahl nitrogen (as protein equivalents), Vitamin C and nitrate accumulation in Amaranthus hypochondriacus. The vegetables were produced in field trials, set up in the University of Nairobi, Kenya, during the long rains period between March and May in 2007 and 2008 using diammonium phosphate (DAP; 20, 40 and 60 kg N ha-1) and manure; 40 kg N kg ha-1,) and the yield, Kjeldahl nitrogen (K-N; a proxy for protein content), vitamin C and nitrate levels were measured. The manure treatment produced little increase in productivity though it increased K-N levels. The DAP treatments produced increases in yield, but these saturated at 40 kg N ha -1. The K-N content of the leaves was high, ranging from 2.5 % to just over 4 %, and, broadly, increased with fertiliser application though the variation between the treatments was lower than that for yields. Nitrate levels, however, also increased with DAP fertilisation, resulting in an increase in the nitrate:K-N at high DAP applications, especially in younger plants. There were no clear correlations between ascorbic acid content and K-N. Nonetheless, the plants grown under different fertilisation regimes can be placed into three broad groups; those characterised with low to moderate K-N contents and low to high ascorbic acid contents, moderate to high K-N and low to high ascorbic acid content, and lastly high K-N and low ascorbic contents. Therefore, the growth environment of amaranth, can have a major impact not only on the productivity of the crop but its nutritional value. In this respect the mineral nutrient supply to the crop is of particular importance.

Onyango, CM;, Harbinson J;, Imungi, J K; Kooten O, Imungi, J K; Kooten O.  2011.  Analysis of the molecular diversity of Kenyan sorghum germplasm using microsatellites. Abstract

Vegetable amaranth is a leafy vegetable traditionally grown in sub-Saharan Africa and Asia where it is the most consumed traditional vegetable. It is considered to have high nutritional quality, containing relatively large amounts of vitamins A and C. We have assessed the influence of the maturity of the vegetable and soil nutrition on the visual and nutritional quality of amaranth. We found that leaf ascorbic acid content is strongly influenced by both maturity and soil nutrition, with leaves of seven week old matured plants having the highest content. β-carotene increased with increasing amount of soil nitrogen and with increasing plant age. The loss of both visual and nutritional quality during storage was influenced more by maturity at harvest and the temperature of storage than the soil nutrition.

Muchoki, CN, Lamuka PO, Imungi JK.  2011.  Reduction of nitrates, oxalates and phenols in fermented solar-dried stored cowpea (Vigna Unguiculata l.) leaf vegetables. Abstract

This study was conducted to determine the effect of fermentation, solar drying and storage duration on the levels of anti-nutrients: nitrates, oxalates and phenols, in cowpea leaf vegetables. The rationale was reduction of the anti-nutrients. Reduction of nutritional stress factors in plant foods increases bioavailability of nutrients, hence improving their quality as foodstuffs. The cowpea leaves were purchased from the local markets, sorted to remove blemished leaves and foreign materials, washed in running tap water. Then, the vegetables were drained and divided into three batches of 16 kg each. One batch was heat-treated in hot water for 3 minutes and then cooled to ambient temperatures, drained and solar-dried. The second portion was acidified to a pH of 3.8, heat-treated, and solar-dried. The third portion was fermented for 21 days, heat-treated, and solar-dried. The three batches of vegetables were spread at different times on drying trays at the rate of 4 kg/m2 and dried in a solar drier to an approximate moisture content of 10%. The dried vegetables were packaged in either polyethylene bags or Kraft paper bags and stored for three months at 18oC, 22o- 26oC or 32oC. Fermentation, heat-treatment and drying of vegetables led to significant (P < 0.05) reduction in nitrates compared to fresh cowpea leaves, but the reduction in oxalates and phenols was not significant. Storage for three months led to significant (P < 0.05) reduction in nitrates in the fermented sample compared to the other samples. The acidified sample had significantly (P < 0.05) higher levels of phenols after three months of storage than the other samples. Samples stored at 18oC had higher levels of oxalates and phenols but lower levels of nitrates, compared to those stored at higher temperatures. Packaging material had no significant effect on the level of nitrates, oxalates and phenols. Data obtained in this study reveal a novel technique for the reduction of anti-nutrients in cowpea leaf vegetables, namely; fermentation followed by solar drying. The increased acceptability of these fermented-dried vegetables would help rural communities in providing better foodstuff with fewer anti-nutrients, thus alleviating micronutrient malnutrition. This novel long-term storage technology can greatly help to deal with the issue of seasonality and will increase food security, especially during the dry season.

Kunyanga, CN;, Imungi JK.  2010.  Quality Characteristics and Acceptability of Bread Produced with Supplementation of Dolichos lab lab Beans. Abstract

The viability of production of good quality and acceptable bread with substitution of wheat flour with Dolichos lab lab (Lab lab purpureus) was investigated. The bread was analyzed for protein, moisture, general bread quality and sensory properties. The protein content of bread was elevated by up to about 20% and the moisture content reduced by about 10% without significant changes in bread taste, odor, volume and general bread quality. Substitution levels of up to 10% produced bread with quality characteristics not significantly different from the control. Sensory evaluation showed no significant differences between the control bread and the Dolichos supplemented breads up to 15% in the sensory attributes of aroma, crumb appearance, texture, crust colour, loaf shape, taste and general acceptability (p < 0.05). The crumb colour changed from creamish white to dull brown and a gradual hardening of crumb texture was observed as the addition of Dolichos lab lab bean flour increased. Above 15% substitution levels, the acceptability declined because of the compact texture of the crumb and the strong beany flavor of the product. Results indicate that acceptable breads can be produced by substitution of up to 15% wheat flour with dolichos bean flour

Githunguri, CM;, Waithaka K;, Ekanayake IJ;, Imungi JK.  2007.  Influence of agro-ecological zones and plant age on the net assimilation, relative and crop growth rates of cassava.. Abstract

Five cassava genotypes were grown at three agro-ecological zones. Plants were sampled for net assimilation, crop growth and relative growth rates at four, six, eight, ten and twelve months after planting. The genotypes were arranged in a randomized complete block design, with four replicates. Cassava at the wetter agro-ecological zones had higher crop and relative growth rates than those at the drier agro-ecological zone. Plant age, agro-ecological zone and genotype effects were not important factors in determining the net assimilation rate of cassava. The lowest yielding genotype had the highest net assimilation rate demonstrating that a high net assimilation rate does not always result into high yields suggesting that net assimilation rate is not a good indicator of growth performance of cassava. The wetter agro-ecological zones had a positive effect on crop and relative growth rates, while the drier agro-ecological zone had a negative effect suggesting that the agro¬ecological zone effect is an important factor in determining them. Cassava crop and relative growth rates were highly positively correlated to root yields. Therefore, breeding and selection for cassava genotypes with the highest crop and relative growth rates and hence yields may be done at the drier agro-ecological zone.

Oiye, SO;, Imungi JK;, Mwangi AM.  2005.  Can Rosemary Spice (ROSMARINUS OFFICINALIS) Stabilize‚-a- Carotene in a Protene -a- Carotene -Rich Soybean-Based Product? Abstract

Background: Addition of ‚-a-carotene-rich foods can be a feasible way to augment vitamin A content in products deficient in vitamin A. However, -a-carotene is highly prone to oxidation and sterioiseomerization that leads to loses. Rosemary spice is locally available and can be used as an antioxidant in organoleptically acceptable levels. Objective: The effects of rosemary spice on the stability of -‚acarotene in a flour formulation with dried carrots as a source was investigated. Methodology: A flour-based product containing 64% full-fat soya flour, 7% meat powder and 29% carrot flour were treated with dried and milled rosemary spice at rates of 0%, 0.1% 0.2%, 0.3% and 0.4% on the basis of weight of the flour. They were then stored for a period of 7 week at 35oC and analyzed for ‚-a-carotene initially and there after at an interval of 2 weeks. Results: At the end of 7 weeks, the sample with no rosemary spice recorded the lowest ‚-a-carotene content (7.22mg/100 g ± 0.10). This was significantly different from samples having rosemary spice (p<0.05). In increasing order in ‚-carotene content sample with 0.1%, 0.3%, 0.2% and 0.4% had 10.64 mg ± 0.07, 10.74 mg ± 0.07, 10.87 mg ± 0.00 and 11.05 mg ± 0.10 per 100 grams of the flour respectively after 7 weeks of storage. Conclusion: It is possible, within a storage period of 7 weeks at 35o, to spare significant amount of ‚-a-carotene in a protein- ‚- carotene-rich soya-based flour using rosemary spice.

Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus.

Mziray, RS, Imungi JK, Karuri EG.  2001.  Nutrient and antinutrient in contents of raw and cooked Amaranthus hybridus. Abstract

Amaranthus hybridus was grown as a leafy vegetables in four sites in Dar‐Es‐Salaam, Tanzania. Freshly harvested leaves from each of the growing sites were analyzed for proximate composition of beta‐carotene, reduced ascorbic acid, minerals iron, calcium, phosphorous and the antinutrients oxalates and nitrates. The leaves from the four sites were bulked and cooked by boiling in distilled water in the ratio vegetable to water of 1:4 then drained. The drained vegetables were analyzed for beta‐carotene, reduced ascorbic acid, iron, calcium, phosphorus, oxalate and nitrate. Results indicated that fresh amaranth vegetables from the four sites had comparable high moisture contents ranging between 85.3% to 86.5%, protein of between 28.2% to 31.6%. The level of minerals calcium, iron and phosphorus ranged between 2062 mg/100 g and 2263 mg/100 g, 108 mg/100 g and 128 mg/100 g and 500 mg/100 g and 553 mg/100 g respectively on dry weight basis. The levels of beta‐carotene of between 25.2 mg/100 g to 37.3 mg/100 g, ascorbic acid of between 455 mg/100 g to 535 mg/100 g. Nitrates and oxalates were at levels of between 501 mg/100 g to 560 mg/100 g and 3383 mg/100 g to 4333 mg/100 g respectively on dry matter basis. On cooking, the levels of beta‐carotene did not change significantly but there were significant reductions (P < 0.05) in the levels of ascorbic acid of up to 50.4%, and 41.4% for phosphorus, while the total nitrate was reduced by 39.2%, and the oxalate by 40.2%. The study established that Amaranthus hybridus leaves grown in four sites of Dar‐Es‐Salaam were good sources of nutrients, had low nitrates levels but high oxalate contents. Furthermore the cooking losses of the nutrients were not excessive, while the antinutrients were substantially reduced.

To determine the prevalence of sucking habits and its association with anterior open bite, posterior cross-bite and transverse dimensions of the Jaws In 3-5-year-olds in Nairobi. Design: A cross-sectional study. Setting: Nairobi, Kenya. Subjects: Three hundred and four children aged 3-5 years (155 boys and 149 girls). Results: The prevalence of digit suckers was 15.8%, nd pacifier users 1.0%. Those with anterior open bite constituted 7.6%. The average intercanine archwidth between 53-63 was 3d.8mm and between 73-83 was 25.4mm. A statistically significant correlation (Pearson!)was observed between digit-sucking and anterior open bite (P<0.01). Concluslon: The present study forms a baseline for future trends in sucking habits among children in Nairobi, Kenya. Low prevalence of sucking habits was found. The average difference between the upper and lower intercanine arch widths was relatively high and prevalence of postenor cross-blte was low. A significant correlation was observed between anterior open bite and digit sucking. The need for orthodontic treatment due to sucking habit was low among children in Nairobi.
