Intestinal absorption of vitamin A in streptozotocin-induced diabetic rats.
(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.
(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 ... -
The metabolic availability of vitamin A (retinol) in streptozotocin-induced diabetic rats.
(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 ... -
Strain variation in vitamin A (retinol) status of streptozotocin-induced diabetic rats.
(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 ... -
Protein utilization in humans as affected by level of dietary fat
(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).
(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.
(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 ... -
Food and Feeding Habits of Juvenile Oreochromis leucostictus Trewavas (Teleostei=Cichlidae) in lake Naivasha and Oloidien, Kenya
(1998-04)An eight month-study (July, 1990 to February, 1991) was conducted at five different littoral habitat types of Lakes Naivasha and Oloidien, Kenya, to examine variations in dietary composition of juvenile Oreochromis ... -
The performance of Husani dairy goats under water restriction in the arid western lowlands, Eritrea
(Bulletin of Animal Health and Production in Africa, 1999)Eighteen adult Husani female goats of approximately equal age and body weight, and in their late pregnancy were purchased from Eritrean western lowlands. They were randomly assigned to three watering regimes (treatments): ... -
Annotated checklist of the non-marine molluscs of Mount Kenya, Kenya
(2001)This paper presents an annotated checklist of the non-marine molluscs of Mount Kenya, based on species records in the literature, museum collections and the results of a National Museums of Kenya Darwin Initiative field ... -
Land-snail faunas of afromontane forests of Mount Kenya, Kenya: ecology, diversity and distribution patterns
(Blackwell Science Ltd, 2001)Aims To (1) describe the distribution patterns of land-snails occurring in afromontaneforest habitats on Mount Kenya, in relation to elevation and aspect; (2) explore therelations between the land-snail faunas and environmental ... -
Flavor Stability of High-Oleic Peanuts Stored at Low Humidity
(2001-08)Shelf-life studies were conducted on roasted high-oleic peanuts (HOP; F1250, BC93Q10) and a reference peanut with normal oleic acid content (NOP, Florunner). HOP contained at least 80% oleic acid and 3% linoleic acid, ... -
THE FIRST GALLIENIELLIDAE (ARANEAE) FROM EASTERN AFRICA
(Bio One, 2002)Toxoniella, a new genus of Gallieniellidae is described from forest remnants on the Taita Hills in Kenya. The genus is characterized by legs with well developed spination, the male palp with posterior tegular extension not ... -
A Review of African Pastoral Production Systems: Approaches to Their Understanding and Development
(2002)Pastoralism is a system that has been in existence for a long time. Scholars have come up with a cornucopia of definitions related to what entails this centuries old art. Many of these scholars agree, though, that ... -
Spiders (Arachnida: Araneae) from black cotton soil habitats of a highland savanna biome in Laikipia, central Kenya
(2004)Spiders were sampled at Mpala Research Centre, Laikipia, Kenya using pitfall trapping and sweep netting. Sampling was conducted from May 2001 to July 2002. A total of 10,487 individuals from 132 species belonging to 30 ... -
