Spatial and functional relationships between air conduits and blood capillaries in the pulmonary gas exchange tissue of adult and developing chickens
(2011)
The documented data regarding the three-dimensional structure of the air capillaries (ACs), the ultimate sites of gas exchange in the avian lung is contradictory. Further, the mode of gas exchange, described as cross-current ...
A stereological comparison of villous and microvillous surfaces in small intestines of frugivorous and entomophagous bats: species, inter-individual and craniocaudal differences
(1997)
The extents of functional surfaces (villi, microvilli) have
been estimated at different longitudinal sites, and in the
entire small intestine, for three species of bats belonging to
two feeding groups: insect- and ...
Parabronchial angioarchitecture in developing and adult chickens.
(University of Nairobi,, 2009)
The avian lung has a highly sophisticated morphology with a complex vascular system. Extant data regarding avian pulmonary angioarchitecture are few and contradictory. We used corrosion casting techniques, light microscopy, ...
Epithelial transformations in the establishment of the blood–gas barrier in the developing chick embryo lung
(Wiley, 2006)
The tall epithelium of the developing chick embryo lung is converted to a squamous one, which participates in formation of the thin blood–gas barrier. We show that this conversion occurred through processes resembling ...
The structural design of the bat wing web and its possible role in gas exchange.
(University of Nairobi,, 2007)
The structure of the skin in the epauletted fruit bat (Epomophorus wahlbergi) wing and body trunk was studied with a view to understanding possible adaptations for gas metabolism and thermoregulation. In addition, gas ...
Microvascular endowment in the developing chicken embryo lung
(The American Physiological Society, 2007)
In the current study, the contribution of the major angiogenic mechanisms, sprouting and intussusception, to vascular development in the avian lung has been demonstrated. Sprouting guides the emerging vessels to form the ...
Erythrina abyssinica prevents meningoencephalitis in chronic Trypanosoma brucei brucei mouse model.
(University of Nairobi, 2014-01)
Human African trypanosomiasis is prevalent in Sub-sahara African countries that lie between 14° North and 29° south of the equator. Sixty million people are at risk of infection. Trypanosoma brucei gambesience occurs in ...
Functional respiratory morphology in the newborn quokka wallaby (Setonix brachyurus)
(Wiley, 2007)
A morphological and morphometric study of the lung of the newborn quokka wallaby (
Setonix brachyurus
) was
undertaken to assess its morphofunctional status at birth. Additionally, skin structure and morphometry ...
Stereological methods for estimating the functional surfaces of the chiropteran small intestine.
(1995)
A tissue sampling protocol has been devised for studying the functional surfaces of chiropteran small
intestine and drawing comparisons within and between species. The goal was to obtain minimally biased
stereological ...
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 ...
