Routine oxygen consumption in different sizes of a tilapia, Oreochromis niloticus (Trewavas) using the closed chamber respiratory method.
(Univesity of NairobiDepartment of Vetinary Anatomy, 1993)Routine oxygen consumption (Vo2) measurements on 54 specimens (0.055-190.4 g) of a tilapia, Oreochromis niloticus (Trewavas) were carried out using two different types of closed respirometers: a modified cuvette for fish ... -
Absorption and pharmacokinetics of phenylbutazone in Welsh Mountain ponies
(Department of Public Health, Pharmacology and Toxicology, University of Nairobi, Kenya., 1986)The disposition of phenylbutazone (4.4 mg/kg), administered intravenously to six Welsh Mountain ponies, was described by a two-compartment open model. Pharmacokinetic parameters were not significantly different after morning ... -
Brucellosis as a cause of human illness in Narok district, Kenya
(Department of Public Health, 1994-08)A retrospective study of medical records was undertaken to investigate the extent of brucellosis in causing ill-health among the Maasai pastoralists of Narok district in Kenya. The low level of brucellosis testing and lack ... -
Fine structure of the nephron in the euryhaline teleost, Oreochromis niloticus.
(Univesity of NairobiDepartment of Vetinary Anatomy, 1994)Ultrastructural studies were carried out on the nephron of a euryhaline teleost, Oreochromis niloticus. The nephron consisted of a renal corpuscle, neck segment, bisegmental proximal tubule and a distal tubule. Renal ... -
The digestive physiology of three East African herbivores: the elephant, rhinoceros and hippopotamus
(University of Nairobi, 2009-08-20)Studies were conducted to compare structural and physiological differences in the digestive functions of three species of large ungulates; the elephant (Loxodonta africana), the Black rhinoceros (Diceros bicornis) and the ... -
Morphometry of some structural parameters affecting oxgyen diffusion in body trunk red muscle at different sizes of a tilapia, Oreochromis niloticus
(Univesity of NairobiDepartment of Vetinary Anatomy, 1994)Morphometric measurements were carried out on some of the structural parameters affecting oxygen diffusing capacity in red muscle of 15 specimens of O. niloticus body weight (b.w.) 0.65–812.3 g. Total capillary length and ... -
Life history traits of an equatorial common carp Cyprinus carpio population in relation to thermal influences on invasive populations
(Univesity of NairobiDepartment of Vetinary Anatomy, 2011-06)Marginal increment ratio analysis of scales collected from the exploited common carp Cyprinus carpio (Linnaeus, 1758) population of Lake Naivasha between June 2008 and November 2009 revealed they were valid for ageing ... -
Astrocytosis as a biomarker for late stage human African trypanosomiasis in the vervet monkey model
(Department of Public Health, Pharmacology and Toxicology, University of Nairobi, Kenya., 2011)The late stage human African trypanosomiasis (HAT) is characterized by central nervous system (CNS) involvement resulting in activation of astrocytes. The aim of the current study was to determine the relationship between ... -
Analysis of public health risks from consumption of informally marketed milk in sub-Saharan African countries
(2000-08-06)Despite policies to discourage them, informal milk markets account for over 80% of milk sales in most sub-Saharan African (SSA) countries. Informal milk market agents include farmer dairy co-operatives, small traders using ... -
Mechanics of running of the ostrich (Struthio camelus)
(University of Nairobi, 2009-08-20)Ostriches have been filmed running fast in their natural habitat. A female ostrich has been dissected and the principal bones, muscles and tendons in a leg have been measured. It is calculated that stresses up to 240 kN ... -
Red muscle fibre and capillary dimensions in different sizes of a tilapia, Oreochromis niloticus (Trewavas)
(Univesity of NairobiDepartment of Medicine, 2006-01)Measurements of muscle dimensions that affect respiration in relation to body weight were carried out in a tilapia, Oreochromis niloticus. The fish used in all measurements weighed 0.65–812.3 g. The data were analysed with ... -
Analysis of Public Health Risks From Consumption of Informally Marketed Milk in Kenya
(Faculty of Agriculture, 2004)Despite an unfavorable policy environment against informal milk markets, these market account for most milk sales in Kenya. Convenient delivery and lower prices are the principal benefits for poor consumers. Current milk ... -
The role of tendon elasticity in the locomotion of the camel (Camelus dromedarius)
(University of Nairobi, 2009-08-20)Several ofthe distal leg muscles ofcamels have very short or even rudimentary muscle fibres. This makes it possible to calculate the elastic extensions of tendons that occur in running, from the leg positions observed in ... -
Allometry of the legs of running birds
(University of Nairobi, 2009-08-20)The principal bones, muscles and tendons of the legs have been measured in a selection of running birds, ranging in size from 0–1 kg quail to 40 kg ostrich. Maximum stride frequencies of the same species have been determined ... -
Mechanical stresses in fast locomotion of buffalo (Syncews coffer) and elephant (Loxodonta africana)
(University of Nairobi, 2009-08-20)Films of buffalo and elephant running, and detailed measurements on dissected legs, have been used to estimate the maximum stresses which occur in locomotion, in certain muscles, tendons and bones. These stresses are similar ... -
Allometry of the limb bones of mammals from shrews (Sorex) to elephant (Loxodonta)
(University of Nairobi, 2009-08-20)Measurements have been made of the principal leg bones of 37 species representing almost the full range of sizes of terrestrial mammals. The lengths of corresponding bones tend to be proportional to (body mass)0·35 and the ... -
Transpiratory water loss and metabolism of beetles from arid areas in East Africa
(Department of Animal Physiology, University of NairobDepartment of Zoology, University of Trondheim, 7055 Dragvoll, NorwayInstitute of Biology and Geology, University of Tromso, P.O. Box 3085, Guleng, 9001 Tromso, Norway, 1987). Carabid beetles have rates of transpiratory water loss and metabolic rates which are higher than those of tenebrionid beetles. Within each family, dry habitat beetles have lower rates of water loss than beetles from mesic ... -
Adaptations of Carabid Beetles to Dry Habitats in East Africa
(Department of Anatomy, University Of Nairobi, 1986)The rates of water loss and humidity preference of carabids from dry tropical habitats have been studied and compared with corresponding data from temperate carabids and tropical tenebrionids. Within each group of beetles ... -
