BACKGROUND MicroRNAs, small non-coding RNAs, are highly expressed in the mammalian brain, and the dysregulation of microRNA levels may be involved in neurodevelopmental disorders such as autism spectrum disorder (ASD). In the present study, we examined whether prenatal valproic acid (VPA) exposure affects levels of microRNAs, especially the brain specific and enriched microRNAs, in the mouse em...
Culturing of primary hepatocytes and stem cell-derived hepatocytes faces a major issue of dedifferentiation due to absence of cell-cell adhesion and 3D structures. One of the possible ways to eliminate the problem of dedifferentiation is mimicking the expression pattern of adhesion proteins during the normal developmental process of liver cells. The purpose of this study was to evaluate the exp...
Cigarette smoking during the prenatal period has been investigated as a causative factor of obstetric abnormalities, which lead to cognitive and behavioural changes associated with schizophrenia. The aim of this study was to investigate behaviour and AChE activity in brain structures in adult rats exposed to cigarette smoke during the prenatal period. Pregnant rats were divided into non-PCSE (n...
BACKGROUND Attention to prenatal care and child delivery is important for the health of women and children, but in the Amazon these indicators tend to be historically unfavorable, in part by geographical and political isolation. In 2003 both Brazilian and Peru governments have finished paving an international road connecting remotes areas in the Brazilian Amazon to the Pacific coast in Peru. ...
Polycystic ovary syndrome (PCOS), a leading cause of infertility, affects approximately 10% of women of reproductive age. The etiology and pathophysiology of PCOS are poorly understood. PCOS is multifaceted and includes reproductive abnormalities and components of the metabolic syndrome such as insulin resistance, obesity, dyslipidemia, and hypertension. Exposure to excess testosterone (T) duri...
Background: Silymarin is a potent inhibitor of apoptosis. The present study aimed to investigate the effect of prenatal silymarin administration during the gestational period on fetal growth. Methods: This experimental study was conducted on 24 virgin female BALB/c mice weighing 20-30 grams. One male animal was caged with two females overnight, and they were examined for the presence of a vagi...
Chronic psychological stress is a risk factor for osteoporosis. Maternal active mastication during prenatal stress attenuates stress response. The aim of this study is to test the hypothesis that maternal active mastication influences the effect of prenatal stress on bone mass and bone microstructure in adult offspring. Pregnant ddY mice were randomly divided into control, stress, and stress/ch...
PURPOSE to analyze the clinical and epidemiological profile, the outcome of pregnancy and the vertical transmission of human immunodeficiency virus (HIV)-infected pregnant women receiving prenatal care at the University Hospital of Santa Maria (HUSM). METHODS A prospective study was conducted on 139 HIV-infected pregnant women attended at the High-Risk Prenatal Care Outpatient Clinic of HUSM,...
BACKGROUND Mandatory reporting of HIV infection to public health authorities, although now common, may deter people from undergoing testing. We examined HIV testing frequency in Alberta before and after mandatory reporting was implemented. We also examined the effect on testing rates among pregnant women when Alberta adopted an opt-out approach to prenatal HIV screening. METHODS Using data fr...
