orofacial clefts, including cleft lip with or without cleft palate (cl (p)), are common congenital malformations, second only to clubfoot in frequency of occurrence. the epidemiology and genetics of this disorder have been studied extensively in various countries by several investigators. the objective of this study is to assess the epidemiology and some genetic aspects of orofacial clefting at...

BACKGROUND Although irregularities in human zona pellucida (ZP) morphology are well described, there is scant literature on the clinical significance of ZP dysmorphology. We, therefore, designed a retrospective cohort trial of ZP dysmorphology to assess the clinical significance of ZP dysmorphology and its affect on IVF outcome. Over the same time period a random sample of 77 cycles of 77 subje...

Gametes and embryo tissues are known to represent a sensitive target to environmental toxicants exposure. Oocyte quality can impact subsequent developmental competence, pregnancy course and even adult health. The major health concern from depleted uranium (DU) is mainly centred on its chemotoxic properties as a heavy metal. Little attention was paid to the impact of uranium on female gamete qua...

Public concerns on phthalates distributions in the environment have been increasing since they can cause liver cancer, structural abnormalities and reduce sperm counts in male reproductive system. However, few data are actually available on the effects of Di-(2-ethylhexyl)-phthalate (DEHP) in female reproductive system. The aim of this study was to assess the impacts of DEHP on zebrafish oogene...

BACKGROUND Meiotic progression, and the number of oocytes surviving to birth, determine the ovarian reserve, yet the control of prenatal oogenesis is poorly understood. We investigated the effects of genetic background and p53 upon oogenesis in mice. METHODS Fetal and neonatal ovaries were analysed in B6CBf1 and B6CBf2 mice from 15.5 to 21 days post-coitum (dpc) and p53 (a tumour suppressor g...

Abnormalities in ovarian function, including defective oogenesis and folliculogenesis, represent a key female reproductive deficiency. Accumulating evidence in the literature has shown that the PI3K/PTEN/Akt and TSC/mTOR signaling pathways are critical regulators of ovarian function including quiescence, activation, and survival of primordial follicles, granulosa cell proliferation and differen...

background: infected with intestinal parasites is one of the most important health and economical problems, which could have different effects, such as diarrheal diseases or death associated. the purpose of this study was to determine the level of prevalence of cryptosporidium and giardia parasites in the vegetable marketed in ilam city. methods: this study was performed on 280 samples of fresh...
