background: immunological factors are important in pregnancy loss because of the interaction between mother and fetus. t-regulatory cells as the component of humeral immune response play important role in the fetu-maternal interface. one of the regulatory mechanisms for these cells is mediated by antigen independent co-stimulatory signals and interaction of cytotoxic t-lymphocyte antigen 4 (b7/...

Reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system. Since studies on sex differentiation in goat fetus are scarce, this study was performed. Twenty-five...

there are morphological and reproductive physiological differences between swamp buffalo (bubaluscarabanensis) and river buffalo (bubalus bubalis). the development of fetus weight and fetus biometry wasreported in river buffalo and other animals but not in swamp buffalo. the aim of this study was to describethe inherent variability in fetus related measurements during swamp buffalo pregnancy. t...

harlequin ichthyosis is a rare and the most severe form of congenital ichthyosis. although prenatal diagnosis is difficult for this disorder, recently, this obstacle has markedly improved with the use of dna-based prenatal diagnosis. here in, we presented a neonate with harlequin ichthyosis born by assisted reproductive technology (art). in this case, the diagnosis of harlequin ichthyosis was n...
