Animal studies have shown that prenatal stress is able to induce long-lasting neurobiological and behavioral alterations in adult offspring. In spite of the facts that hippocampus is sensitive to early developmental influences and its known functional importance in learning and memory, few data are available on the effect of prenatal stress on the structure of hippocampus. Therefore, this study...

background substance abuse during pregnancy leads to considerable adverse effects in mothers and their infants. objectives the purpose of this study was to evaluate perinatal complications in opium-addicted mothers and their newborns, exposed to opium in utero. patients and methods during a one-year period (2008 - 2009), 45 opium-addicted mothers and their newborns were enrolled in a case-contr...

BACKGROUND Metabolic and endocrine environment during early life is crucial for metabolic imprinting. When dams were fed a high fat diet (HF diet), rat offspring developed hypothalamic leptin resistance with lean phenotype when weaned on a normal diet. Interestingly, when grown on the HF diet, they appeared to be protected against the effects of HF diet as compared to offspring of normally fed ...

BACKGROUND The polycystic ovary syndrome (PCOS) affects approximately 6-10% of women of reproductive age and is characterized by chronic anovulation and hyperandrogenism. However, a comprehensive understanding of the mechanisms that dictate androgen overproduction is lacking, which may account for inconsistencies between measures of androgen excess and clinical presentation in individual cases....

BACKGROUND/AIMS Maternal diet may have an effect on the health of the offspring in middle and later life. This study used the laboratory rat as an animal model to examine whether the fibre content of the maternal diet during pregnancy affected subsequent development of colonic diverticula in the offspring fed lifelong fibre deficient or higher fibre diets. METHODS The parents of experimental ...

Flaxseed is the richest source of the mammalian lignan precursor secoisolariciresinol diglycoside (SDG). Because lignans have estrogen agonist or antagonist properties, the objective of this study was to determine whether feeding flaxseed to rats during a hormone-sensitive period has reproductive effects. Rat dams were fed a basal diet or the basal diet supplemented with 10% flaxseed, 5% flaxse...

Placental insufficiency in the rat results in intrauterine growth restriction and development of hypertension in prepubertal male and female growth-restricted offspring. However, after puberty, only male growth-restricted offspring remain hypertensive, whereas female growth-restricted offspring stabilize their blood pressure to levels comparable to adult female controls. Because female rats rea...

background the hippocampus is responsible for memory. a diet full of antioxidants improves brain damage and cognitive function. regard the antioxidant effects of zingiber officinalis (ginger) and its flavonoids components. objectives the aim of this study was to evaluate the effect of the extract of ginger on memory by using hippocampus tissue of the male offspring of rats. materials and method...
