The basic helix-loop-helix transcription factor, NEUROG3, is critical in causing endocrine commitment from a progenitor cell population in the developing pancreas. In human, NEUROG3 has been detected from 8 weeks post-conception (wpc). However, the profile of its production and when it ceases to be detected is unknown. In this study we have defined the profile of NEUROG3 detection in the develo...

background: fetal alcohol syndrome is associated with numerous problems in the development and function of the brain. learning and memory deficits are among well known effects of prenatal exposure to alcohol. objective: this study aimed to examine the spatial working memory of 60-day old rats who were exposed to alcohol during their fetal life and to find the relation between the possible alcoh...

A combination of mouse inbred strains was studied, in which foetal but not placental weight is greater in the F1 hybrid than in the inbred litters. Gestation period was found to be shorter for the F1 hybrid than for the inbred litters. It is concluded that, insofar as the length of gestation is inversely related to the mass of the conceptuses, it is the foetus rather than the placenta which mat...

It was demonstrated in this study that the mean values of the different red blood cell count and white blood cell parameters showed significant changes during gestation. RBC, PCV and Hb increased while total WBC and segmented neutrophils increased after the second gestation period in the second period. The numbers of total leucocytes and segmented neutrophils increased after the second period.

Previously, the concept of a gestation period of sheep shorter than 121 days was unheard of in the field of sheep biology. Our findings during a farmers’ survey in the Lotkho area of Chitral, Pakistan, revealed that the sheep native to the region, locally called “Kari”, gestates for a period of only three months. This duration is 25-40% short of the usual gestation length and is shorter than ev...
