Habitat Preferences, Feeding Habits, Leght-Weight Relationship and Relative Condition Factors of Juvenile Tilapias in Lake Naivasha, Kenya.

Mwangi, Benson (1992)
Economic factors affecting the level of beef production from ranching: an example of Kenya's cattle sector

Nyariki, Dickson M.; Munei, K. (1993)

An econometric method was used to determine the economic factors that influence the level of beef production from ranches in one of the range areas in Kenya. The study also used both cross section and time-series data ...
Intestinal absorption of vitamin A in streptozotocin-induced diabetic rats.

Tuitoek, Prisca J.; Thomson, A.B.; Rajotte, R.V.; Basu, T.K. (Diabetes Research, 1994)

Diabetes mellitus is known to be associated with enhanced intestinal absorption of lipids. A validated in vitro technique was used to examine the uptake of (3H) retinol (a lipid soluble vitamin) into the jejunum and ileum ...
Effect of Insulin Treatment or Zinc Supplementation on Vitamin A Status in Streptozotocin-Induced Diabetic Rats.

Tuitoek, Prisca J.; Lakey, J.; Rajotte, R.; Ziari, S.; Tsin, A.; Basu, T. (Journal of Clinical Biochemistry and Nutrition, 1995)

A Using streptozotocin-induced diabetic rats, we examined the effects of zinc supplementation and insulin treatment on the metabolic availability of vitamin A. All diabetic animals exhibited an elevated plasma glucose (>18 ...
Strain variation in vitamin A (retinol) status of streptozotocin-induced diabetic rats.

Tuitoek, Prisca J.; Lakey, J.R.; Rajotte, R.V.; Basu, T.K. (International Journal for Vitamin and Nutrition Research, 1996)

Decreased plasma concentrations of vitamin A (retinol) and retinol-binding protein have been previously identified in human subjects with type I diabetes mellitus. The present study was undertaken to investigate the effects ...
The metabolic availability of vitamin A (retinol) in streptozotocin-induced diabetic rats.

Tuitoek, Prisca J.; Basu, T. K . (University of Alberta (Canada), 1996)

Using non-diabetic control and streptozotocin-induced diabetic male Wistar rats of 4-6 week duration, the metabolic availability of vitamin A (retinol) was examined. Animals were fed ad libitum a nutritionally complete ...
Protein utilization in humans as affected by level of dietary fat

Kandiah, J.; Tuitoek, Prisca J.; Kies, C. (Elsivier, 1996-01)

The objective of the project was to determine the effects of level of fat with or without manganese supplementation of diets on protein status of humans. Fourteen healthy adult humans participated in a 61 day study in which ...
Streptozotocin-induced diabetes in rats is associated with impaired metabolic availability of vitamin A (retinol).

Tuitoek, Prisca J.; Ziari, S.; Tsin, A.T.; Rajotte, R.V.; Suh, M.; Basu, T.K. (The British Journal of Nutrition, 1996-04)

Using streptozotocin-induced diabetic Wistar rats, studies were carried out to examine the metabolic availability of vitamin A in the plasma, liver and the retina of the eye. Control and diabetic rats were fed ad lib. on ...
Streptozotocin-induced diabetes lowers retinol-binding protein and transthyretin concentrations in rats.

Tuitoek, Prisca J.; Ritter, S.J.; Smith, J.E.; Basu, T.K. (The British Journal of Nutrition, 1996-12)

Retinol-binding protein (RBP) and transthyretin (TTR) in the plasma, liver and kidney, retinol in plasma, and total vitamin A in the liver were measured in rats 6 weeks after diabetes mellitus had been induced by streptozotocin ...

Nyariki, Dickson M. (1997)

Abstract The problem of food insecurity in sub-Saharan Africa is currently one of the principal Concerns of policy makers. Food insecurity Is an Issue that has engaged researchers, Politicians, And donors in debate on ...
Household food insecurity in sub-Saharan Africa: lessons from Kenya

Nyariki, Dickson M.; Wiggins, S. (1997)

Food security is one of the most challenging issues in sub-Saharan Africa which has continued to generate debate. Literature abounds showing that Africa is the only region in the world where per capita food production has ...
Diversity, Species Composition And Some Ecological Aspects Of Terrestrial Molluscs In Mount Kenya National Park - Kenya

Warui, Charles M. (1998)

This study was done between November 1996 and July 1997 and sought to establish the species composition of terrestrial molluscs in Mt. Kenya National Park. The study also sought to investigate the effect of soil pH, ...
