Inheritance and incidence of atresia coli in Holstein cattle
Incidence of atresia coli was monitored from 1974 through 1989 in the University of Illinois Holstein herd. This period comprised three phases. Phase I was the period from January, 1974 through August, 1983. The period from September, 1983 through March, 1986 was designated as phase II. The third …

The differentiation of extrahepatic biliary atresia from the neonatal hepatitis syndrome
… with cholestasis, between extrahepatic biliary atresia (EHBA) and the neonatal hepatitis syndrome (NHS) is important in that laparotomy is always indicated in EHBA but is undesirable in NHS. This differentiation is particularly difficult in those infants with complete cholestasis. Hepatobiliary …

Hydraulically controlled magnetic bougienage for correction of long-gap esophageal atresia
… separated by a gap, which is called esophageal atresia. Esophageal atresia with a relatively short gap can be directly corrected with surgery, whereas babies with a relatively long gap requires a treatment over several weeks to stretch the esophageal pouches. In this thesis, we have designed and …

Equol inhibits growth, induces atresia, and inhibits steroidogenesis of mouse antral follicles
… antral follicle growth, increases follicle atresia, and inhibits steroidogenesis in the adult mouse ovary. Ovarian antral follicles from adult CD-1 mice were cultured with vehicle control or equol (600 nM, 6 µM, 36 µM, 100 µM) for 48 and 96 h. Follicle diameters were measured every 24 h to …

Biliary atresia at Red Cross War Memorial Children's Hospital: A retrospective descriptive study reviewing the age of presentation, clinical course and outcome of infants presenting to RCWMCH with biliary atresia
Background: Biliary atresia (BA) is a progressive obstructive cholangiopathy of unknown aetiology, occurring during the perinatal period. If left untreated it rapidly progresses to hepatic fibrosis and cirrhosis, with death occurring within 2 years. It is the leading cause of end-stage liver …

An investigation of the Ciliary Protein PKHD1 in Cyst development in liver disease: clues to the pathogenesis of Biliary Atresia
Biliary atresia is a common form of paediatric liver disease, with progressive, inflammatory obliteration of the biliary tree, leading to liver failure early in life. Mutations in PKHD1, encoding the ciliary protein fibrocystin, are associated with autosomal recessive polycystic kidney disease …

Mechanism of methoxychlor toxicity in mouse ovarian antral follicles
… atrophy. MXC reduces fertility by increasing atresia of antral follicles and by decreasing numbers of healthy antral follicles in adult female mice. Further, MXC inhibits growth and induces atresia of mouse antral follicles in vitro. Little is known, however, about the mechanisms by which MXC …

Mechanism of Bisphenol A toxicity in adult mouse ovarian antral follicles
… time, follicles not marked for ovulation undergo atresia, a normal process of follicular cell death. Disturbances in follicle growth or atresia could impair healthy oocyte development and ovulation, ultimately affecting fertility. Steroidogenesis is required for healthy development and functioning …

Synthetic Studies Of Biologically Active Molecules: Irl 2500, Bruceantin, And Biliatresone
… groups will also be discussed. Part 3: Biliary atresia is a rare disease that is the most common indication for liver transplant among the pediatric population. Biliatresone was discovered to be an environmental toxin that recapitulates the biliary atresia phenotype. Analogs of biliatresone the …

Origins of Systemic to Pulmonary Collateral Arteries and their Relative Frequencies in Patients with Pulmonary Artery Atresia or Stenosis as determined using Multidetector Computed Tomography Angiography
… Critical to the management of pulmonary atresia (PA) or pulmonary stenosis (PS) is accurate and comprehensive knowledge of the vascular network supplying the lungs. This vascular network can be exceedingly complex as it may include a wide variation of systemic to pulmonary collateral …

Effects of methoxychlor and its metabolites on mouse antral follicles
… will be more sensitive to growth inhibition and atresia induced by MXC and its metabolites. in vitro as well as in vivo. Results indicate that ovarian antral follicles of ESR1 OE are more sensitive to growth inhibition and atresia induced by MXC and its metabolites compared to controls. Moreover, …

Toxicity of TCDD in the mouse antral follicle
… actions of TCDD on steroidogenesis, growth, and atresia of intact mouse antral follicles in vitro. Interestingly, TCDD has been shown to act mainly through binding to the aryl hydrocarbon receptor (AHR) in other tissues, and the AHR has been identified as an important factor in ovarian function. …

An analysis of neonatal mortality following gastro-intestinal and/or abdominal surgery in a tertiary hospital in South Africa

Describing The Nutritional Outcomes Following Paediatric Liver Transplantation At A Tertiary Hospital In South Africa
… 24-months post-transplant respectively. Biliary atresia was the diagnosis in 89,5% of children with stunting at 24 months vs in 50% of children without stunting at 24 months post-transplant (p = 0.03). Mean pre-transplant albumin was lower in children with stunting at 24 months post-transplant …

Fluorescence in Situ Hybridization Analysis of Human Embryos Derived From in Vitro and in Vivo Matured Oocytes

Certain congenital anomalies : some psycho-social implications in adulthood

Influences of atrazine on gonadal differentiation in Xenopus laevis tadpoles during metamorphosis
