The first mature cells to arise in the developing mammalian embryo belong to the erythroid lineage. This highlights the immediacy of the need for red blood cells during embryogenesis and for survival. Linked with this pressure is the necessity of the embryo to obtain and transport iron, synthesize hemoglobin, and then dispose of the potentially toxic heme via the stress-induced protein heme oxy...

Embryonic development of sharpsnout seabream (Diplodus puntazzo) was studied at eleven water temperatures (two degree intervals from 12 to 32°C). Embryos successfully developed at temperatures of 16-28°C. Cells did not divide at the temperature extremes of 12 and 32°C. Total mortality was observed by the 128 cleavage stage at 14°C and all eggs were dead by the time the embryos extended 2/3 of t...

Sox genes encode transcription factors that are involved in a variety of embryonic developmental pathways. Sox2 and Sox14 are located on the same chromosomal arm in several mammalian and bird species and on the basis of comparative maps were suggested as candidate genes for the major sex-determining locus on tilapia LG3. We have sequenced the sox2 and sox14 genes in four tilapia species and map...

the government of the united republic of tanzania has initiated the integrated management of childhood illness program to improve the health and wellbeing of children.tanzania's under-five mortality rate is still 1.7 times higher than the world average and, in order to achieve its millennium development goal 4 target, its annual reduction rate is quite low at 2.2. the main aim of the study is t...

Atropa belladonna is a highly poisonous plant which contains variety of active alkaloids such as atropine, scopolamine and many others. In homeopathy, its preparation used to cure number health conditions baby teething, pain or infection However, due toxic nature adverse teratogenic effect, it important investigate the possible toxicity safety level mother tincture. this study, zebrafish embryo...

Salinity intrusion in coastal areas due to climate change is alarming. In this study, the effects of salinity on embryonic and larval development striped catfish ( Pangasianodon hypophthalmus ) were studied experimentally. Embryos larvae exposed seven treatments (0, 2, 4, 6, 8, 10, 12 ppt), each with three replications. Considerable survivability embryos was recorded up 6 ppt salinity. Mortalit...

BACKGROUND Recent research has documented fertility decline after the peak of pandemic-associated mortality during the 1918 influenza pandemic. Yet the time interval between the mortality peak and the dip in fertility and its contributing mechanisms remains a line of debate. OBJECTIVE This study examines the inter-temporal association between pandemic-associated mortality and subsequent birth d...

Copper-based fungicides have been used to control various plant diseases for more than one hundred years and play very important roles in agriculture. Accumulation of copper freshwater environment pose severe threats human health the environment. The current study evaluated developmental behavioral toxicity PEG@Cu NCs (copper nanoclusters), Kocide® 3000 hydroxide), Cu(CH3COO)2 acetate) zebrafis...
