Actual relationships of human size to strength have remained undetermined despite decades of research by many investigators because the determination necessitates valid theoretical formulation and selection through three essential criteria of a proper sample of subjects for empirical testing. The formula is: Vol.(Wt.) strength e k Rt. Champion weightlifters satisfy all criteria, and, by minor a...

morphological changes in polyvinyl butyral (pvb) electrospun nanofibres can be acquired by preparation of pvb spinning solution in different solvents.  accordingly, three solvents, including ethyl alcohol, n-butanol and isopropanol, with diverse physical properties (e.g. boiling point, density, dipole moment and dielectric constant) were used to prepare polyvinyl butyral (pvb) spinning solution...

Culture technology have permitted the generation of an artificial skin using human neonatal stem cells. A major advantage of this model is that epithelial-mesenchymal interactions are maintained. We have studied some morphological aspects concerning tissue organisation and cell differentiation using immunohistochemistry and electron microscopy. The epidermal equivalent was composed by a stratif...

The vagina is one organ of the body which has not been studied exhaustively. Moreover, most of the studies found in the contemporary literature have been performed on women affected by a variety of genital diseases. In the present study the vaginal epithelium was examined with a histological method, morphometry, whereby cyclical changes related to hormonal variation during the menstrual cycle w...

The vitellogenic process in Culex quinquefasciatus, which is triggered by a blood meal, involves the synthesis, distribution and storage of the nutrients necessary for embryo development. The fat body of an adult female Cx. quinquefasciatus revealed two cell types: large trophocytes and small, eosinophilic, "oenocyte-like" cells, which show no morphological changes throughout the gonotrophic cy...
