Microvascular growth, development, and remodeling in the embryonic avian kidney: the interplay between sprouting and intussusceptive angiogenic mechanisms
(Wiley, 2005)
Embryonic development is associated with extensive vascular growth and remodeling. We used immunohistochemical, light and electron microscopical techniques, as well as vascular casting methods to study the developing chick ...
Development and spatial organization of the air conduits in the lung of the domestic fowl, Gallus gallus variant domesticus.
(University of Nairobi,, 2008-09)
We employed macroscopic and ultrastructural techniques as well as intratracheal casting methods to investigate the pattern of development, categories, and arrangement of the air conduits in the chicken lung. The secondary ...
Morphological characterization of the seminiferous cycle in the goat (Capra hircus): a histological and ultrastructural study.
(University of Nairobi., 2000-05)
The cycle of spermatogenesis/seminiferous cycle was investigated in the goat testis using both light and electron microscopy techniques. Using the various cell associations and the accompanying changes in spermatid shape ...
Relative importance and determinants of landowners’ transaction costs in collaborative wildlife management in Kenya: an empirical analysis
(2003)
Collaborative management of protected areas—which involves state agencies, local communities and other stakeholders—has been identified as a promising approach of organising nature conservation. However, as a complex ...
Immunisation of cattle against heartwater by infection with Cowdria ruminantium elicits T lymphocytes that recognise major antigenic proteins 1 and 2 of the agent.
(University of Nairobi., 2002-02)
There is growing evidence that immunity of cattle to Cowdria ruminantium infection is mediated by T lymphocytes. C. ruminantium antigens that stimulate these responses are therefore of considerable importance to the ...
Analysis of production objectives and breeding practises of dairy goats in Kenya.
(2009)
Production objectives and breeding practices of smallholder households participating in dairy goat breeding projects were analysed in relation to their ability to bring about sustainable genetic improvement in the dairy ...
Mode of inheritance of common bean (Phaseolus vulgaris L.) traits for tolerance to low soil phosphorus (P)
(2007)
Low soil phosphorus (P) has been singled out as a major constraint leading to perpetually low bean (Phaseolus vulgaris L.) grain yield far below the expected yield potential. In developing countries beans are mainly produced ...
Risk preference and optimal enterprise combinations in Kahuro division of Murang'a district, Kenya
(2005)
Financing smallholder farming has been one of the major concerns of Kenya's agricultural development efforts. Many credit programs have evolved over the years but with dismal performance. In a study that sought to find the ...
Evaluation of the recognition of Theileria parva vaccine candidate antigens by cytotoxic T lymphocytes from Zebu cattle.
(University of Nairobi., 2008-02)
East Coast fever (ECF) is a highly fatal lymphoproliferative disease of cattle caused by Theileria parva, a tick-borne intracellular apicomplexan parasite. Parasite antigens that are targets of protective cytotoxic T ...
The Prevalence of Hydatidosis in Slaughtered Livestock in Kenya
(2004)
Using the post-mortem meat inspection records available in the department of veterinary services, Kabete, a retrospective abattoir survey was carried out to determine the prevalence of hydatidosis in cattle sheep, goats ...
