Extra-embryonic

Embryonic and fetal exposure to maternal obesity causes several maladaptive morphological and epigenetic changes in exposed offspring. The timing of these events is unclear, but changes can be observed even after a short exposure to maternal obesity around the time of conception. The hypothesis of this work is that maternal obesity influences the ovine preimplantation conceptus early in pregnancy, and this exposure will affect gene expression in embryonic and extraembryonic tissues.

The breed has great potential in meeting demands of local food producers, commercial farmers and biotechnology sector of specific pathogen-free (SPF) eggs, the former valuing the breed for its egg weight (EW), EL, age at first egg (AFE), body weight (BW), and the latter for its yield of extraembryonic fluid (YEF) in 12.5-day embryos, ratio of extraembryonic fluid to egg weight, and embryo mass.

The fifth edition of BRS Embryology has afforded me the opportunity to further finetune a work that was already a highly rated course review book as well as an excellent review for the USMLE Step 1. This fine-tuning is a result of the many students who have contacted me by e-mail to point out errors and give suggestions for improvement. I appreciate this student feedback very much. In the fifth edition, I have placed clinical images closer to the corresponding text to make reviewing more efficient.
