background: acceptance of uterus and reaction between endometrium and embryo has an important role for implantation. muc1 an integral membrane mucin is expressed on the apical surface of uterine epithelial cells and could have effects on its receptivity. objective: the aim of this study was to evaluate the changes in muc1 expression of gravid mouse endometrium with and without hyperstimulation ...

Congenital T. cruzi infections involve multiple factors in which complex interactions between the parasite and the immune system of pregnant women play important roles. In this study, we used an experimental murine model of chronic infection with T. cruzi to evaluate the changes in the expression of inhibitory receptors and the polyfunctionality of T cells during gestation and their association...

Enzyme activities involved in glucose utilization via the Embden-Meyerhof and the pentole phosphate pathways were compared in subcellular fractions prepared from: (a) normal mammary glands excised from virgin, pregnant, lactating, and postlactating C3H mice; (6) HAN* outgrowths from virgin mice; (c) spontaneous mammary adenocarcinomas from virgin, pregnant, and lactating mice; and (d) mammary a...

BACKGROUND Placenta immunomodulatory ferritin (PLIF) cDNA was recently cloned from the human placenta, where it is expressed in syncytiotrophoblast and decidual mononuclear cells. PLIF and its subcloned bioactive domain (C48), expressed in Escherichia coli, are immunosuppressive proteins and induce pronounced IL-10 production in vitro and in vivo. METHODS AND RESULTS PLIF serum level, measure...

Perfluorooctanesulfonate (PFOS) is a widely spread environmental contaminant. It accumulates in the brain and has potential neurotoxin effects. Due to chemical properties, PFOS shows persistency in the environment and therefore has potential hazardous effect. The risk of possible intra uterine exposure to PFOS poses a health concern for developmental effects. The goal of this study was survey o...

In studies of marginal biotin deficiency induced experimentally in adults, increased urinary excretion of 3-hydroxyisovaleric acid (3HIA), which likely reflects decreased activity of the biotin-dependent enzyme beta-methylcrotonyl-CoA carboxylase, and decreased activity of the biotin-dependent enzyme propionyl-CoA carboxylase (PCC) in peripheral blood lymphocytes have been validated as indices ...

This study was divided into three experiments, (a) The levels of selenium and glutathione peroxidase (GSH-PX) activity were determined for various developmental states of the mammary gland: normal (virgin, pregnant, and lactating); preneoplastic hyperplastic outgrowth lines; and neoplastic mammary tissues. Tissues from the pregnant and lactating mice had higher sele nium concentrations and GSH-...

Acute infection with Toxoplasma gondii (T. gondii) during pregnancy is associated with adverse outcomes. The mechanisms that cause this phenomenon are not clear. Regulatory T cells (Tregs) are involved in maternal tolerance, and here we observed a decrease in the absolute numbers of CTLA-4(+) Tregs and PD-1(+) Tregs in spleen and at the fetal-maternal interface in T. gondii-infected mice. Our r...

Methomyl is an oxime carbamate pesticide that is widely used in the Philippines. This insecticide is known to be an endocrine disrupting chemical and a potent genotoxic in mammalian cells. However, limited studies were conducted specifically on its direct effects on estrous cycle and its teratogenic effect. This study aimed to (a) assess the effect of methomyl on the body weight and on the estr...
