Human-animal chimeric embryos are embryos obtained by introducing human cells into a non-human animal embryo. It is envisaged that the application of human-animal chimeric embryos may make possible many useful research projects including producing three-dimensional human organs in animals and verification of the pluripotency of human ES cells or iPS cells in vivo. The use of human-animal chimer...

Two hundred and forty Hubbard Classic broiler chicks were used in a 35 day trial at Chittagong Veterinary and Animal Science University farm, Bangladesh to study the effects of supplemental choline chloride on performance parameters, carcass characteristics and their association in commercial broiler. All birds had free access to ad libitum feeding. Birds were fed four types of diet i.e. diet w...

Ca(2+) signaling pathways control many physiological processes in almost all types of animal cells such as fertilization, muscle contraction, hormone release, and learning and memory. Each animal cell type expresses a unique group of molecules from the Ca(2+) signaling 'toolkit' to control spatiotemporal patterns of Ca(2+) signaling. It is generally believed that the complex Ca(2+) signaling 't...

to achieve the desired level of animal performance providing animal food supplies containing mineral elements is essential. for this purpose, mineral elements of 8 important rangeland species, including ferula ovina, prangus uloptera, medicago sativa, lotus goeblia, trifolium montanum, melilotus officinalis, sanguisorba minor and stachys inflate, were measured at different growth stages in the ...

Broad-scale animal diversity patterns have been traditionally explained by hypotheses focused on climate-energy and habitat heterogeneity, without considering the direct influence of vegetation structure and composition. However, integrating these factors when considering plant-animal correlates still poses a major challenge because plant communities are controlled by abiotic factors that may, ...

background continuous epidural analgesia with catheterization is a useful technique, because it has a wide adaptation range and provides prolonged analgesia. problems that may arise from long-term epidural analgesia are changes in the analgesic area, duration of analgesia and catheter-related problems. few articles have evaluated gradual changes of long-term epidural analgesia. in the animal mo...

Pasricha, deMonte and Gupta (1931) reported the isolation of four types of typhoidphage but the properties of the different types were not then described. These four types not only form plaques or clearings which differ in their morphology but give the ' reciprocal cross tests '. A secondary culture (produced after the action of any one of the types on a susceptible strain of Bact. typhosum) is...

Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system with an autoimmune attack on the components of the myelin sheath and axons. The etiology of the disease remains largely unknown, but it is commonly acknowledged that the development of MS probably results from the interaction of environmental factors in conjunction with a genetic predisposition. Curr...
