Histomorphometry of Golden Hamster Ovaries
Introduction: Genital system is important herd in animal's creation. It is necessary for animal reproduction. Mammal has two sex in genital system such as male and female in separated animals. Animal reproduction destroyed by disorder of genital system. In this case, animals cannot produce an animal similar to them. Finally it cause overthrow a species of animals. Methods: Histomorpholog...
متن کاملHamster female protein, a sex-limited pentraxin, is a constituent of Syrian hamster amyloid.
Female protein (FP) is a pentraxin of Syrian hamster which is a homologue of two human pentraxins, C-reaction protein (CRP) and amyloid P component (AP). Functionally, FP has been shown to be similar to CRP, although FP has more homology at the amino terminus with AP. The present work investigated amyloid in the Syrian hamster to determine whether FP was involved in a manner analogous to AP. FP...
متن کاملFemale Meiotic Sex Chromosome Inactivation in Chicken
During meiotic prophase in male mammals, the heterologous X and Y chromosomes remain largely unsynapsed, and meiotic sex chromosome inactivation (MSCI) leads to formation of the transcriptionally silenced XY body. In birds, the heterogametic sex is female, carrying Z and W chromosomes (ZW), whereas males have the homogametic ZZ constitution. During chicken oogenesis, the heterologous ZW pair re...
متن کاملMaternal uniparental disomy of chromosome 13 in a phenotypically normal child.
A case of maternal uniparental disomy of chromosome 13 is described. The subject is a phenotypically normal male who inherited a t(13;13)(p11.2;p11.2) from his mother who is a carrier of this translocation. The mother was ascertained through a history of recurrent abortion and is phenotypically normal. The translocation in both subjects was studied by cytogenetic and DNA analysis and appears to...
متن کاملhomozygosity for a robertsonian translocation (13q;14q) in a phenotypically normal 44, xx female with a history of recurrent abortion and a normal pregnancy outcome
background: robertsonian translocations are structural chromosomal abnormalities caused by fusion of two acrocentric chromosomes. in carriers of such translocations, different modes of segregations would result in the formation of either balanced (alternate segregation mode) or unbalanced (adjacent 1, adjacent 2, and 3:1 segregation modes) gametes. in addition, there is an increased risk for im...
