Energetics of lizard embryos are not canalized by thermal acclimation.
In some species of ectotherms, temperature has little or no effect on the amount of energy expended during embryonic development. This phenomenon can result from either of two mechanisms: (1) a shorter incubation period at higher temperatures, which offsets the expected increase in metabolic rate, or (2) a compensatory decrease in the rate at which embryos expend energy for maintenance. To dist...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولMelatonin increases cleavage rate of porcine preimplantation embryos in vitro.
Melatonin has been used to promote in vitro embryo development in different species. This study determined the effects of melatonin on in vitro porcine embryo development; in particular, cleavage rate, blastocyst rate, and blastocyst cell number. Starting 5 hr after insemination, porcine zygotes were cultured in porcine zygote medium 3 (PZM-3) culture medium supplemented with melatonin at incre...
متن کاملThermal Acclimation of Heart Rates in Reptilian Embryos
In many reptiles, the thermal regimes experienced by eggs in natural nests vary as a function of ambient weather and location, and this variation has important impacts on patterns of embryonic development. Recent advances in non-invasive measurement of embryonic heart rates allow us to answer a long-standing puzzle in reptilian developmental biology: Do the metabolic and developmental rates of ...
متن کاملMorphine delays fovea development in the eyes of Wistar rat embryos possible involvement of corticosterone
Abstract* Introduction: Visual system have been considered as among important sensory system in animals’ life span and their survival is closely related to normal visual system functioning. Since in previous studies it have been revealed that morphine consumption during pregnancy could lead to defect and delay in nervous system development in the embryos, in the present study, changes induc...
