Myopia is amongst the most common refractive errors in the world. Both environmental and genetic factors are attributed to its causation, however all factors contributing to the development of myopia is yet to be found. Recent studies show presence of sex hormone receptor in the eyes. This has been shown to have a role in the development of various ocular pathologies. The second to fourth finge...

OBJECTIVE The objective of this study was to assess the validity of women's reports of recent unprotected sex by testing for prostate-specific antigen (PSA) in vaginal samples. STUDY DESIGN The authors conducted prospective research with 332 female sex workers attending 2 public dispensaries in Madagascar. RESULTS Among women who reported no sex or protected sex only within the past 48 hour...

Most current linkage analyses assume identical fractions of meiotic recombination between homologous marker loci of the two sexes. This assumption is not realistic, because considerable sex-related differences have been observed in recombination fraction. In this paper, a general EM-based algorithm is presented to estimate sex-specific recombination fractions for a mixed set of molecular marker...

We report a case of double uterine tumor resembling ovarian sex cord tumor (UTROSCT). The tumor was composed of sex cord-like cords, nests and tubules, and bundles of myoid cells. The lesion was interesting especially in regard to histogenesis of intratumoral myoid cells. It is not known whether these cells are neoplastic or whether they represent preexisting myometrial smooth muscle cells entr...

Abstract This study aimed to detect the quantitative trait loci (QTL) which affecting growth traits in some parts of chromosomes 1 Sanjabi lambs. The population consisted six groups fathers had an average 39.17 Initially, were genotyped for eight microsatellite markers on chromosome 1, and offspring heterozygote genotyped. body’s weight at birth, 3, 6, 9, 12 months, corrected fixed effects year...

In Drosophila, the enhancer-trap line mgm1 is already specifically expressed in male germ cells. Staining is first detected in 10-hour-old embryos and it is found in later stem cells. This line, which reveals the earliest sex-specific gene expression in the germline known so far, is a useful molecular marker to assess the sexual pathway that germ cells have entered before any overt sexual dimor...
