Abstract BACKGROUND: Although the pathogenesis of androgenetic alopecia is not completely understood, the roles of genetic susceptibility and androgens are well-known. A lower ratio of the second digit (index finger = 2D) to the fourth digit (ring finger = 4D) length has been hypothesized to reflect pre...

PURPOSE: To investigated the effects of exposure to an 1800 MHz electromagnetic field (EMF) on bone development during the prenatal period in rats. METHODS: Pregnant rats in the experimental group were exposed to radiation for six, 12, and 24 hours daily for 20 days. No radiation was given to the pregnan...

Schizophrenia is a severe psychiatric disorder that results in a significant disability for the patient. The disorder is characterized by impairment of the adaptive orchestration of actions, a cognitive function that is mainly dependent on the prefrontal cortex. This behavioral deficit, together with cel...

OBJECTIVE Investigate the effect of exposure to smoking during pregnancy and early childhood on changes in the body mass index (BMI) from birth to adolescence.METHODS A population-based cohort of children (0-5 years old) from Cuiabá, Midwest Brazil, was assessed in 1999-2000 (n = 2,405). Between 2009 an...
Previous studies have shown the adverse effects of gestational diabetes on hippocampal neuronal density in animal models. This study was conducted to determine the effect of gestational diabetes on retinal ganglionic cell density, the thickness of the retinal layer and apoptotic ganglionic cell density i...

Previous study has shown the adverse effects of gestational diabetes on hippocampal neuronal density in animal model. This study was conducted to determine the effect of gestational diabetes on rat cerebellum in early postnatal life. In this experimental study, 10 dams randomly allocated into control and...
The current annual consumption of insecticides in agriculture in Brazil is over three million tons. The exposure happens through food that is contaminated with toxic waste and respiratory and dermal absorption. Biological control with Bacillus thuringiensis Berliner (Bt) has assumed increasing importance...

Prenatal stresses such as water deprivation affect developmental process of embryo. This study evaluated the effects of water deprivation in pregnant mother on histological parameters of testis of offspring. Pregnant rats were divided into two groups (control and experimental). In experimental animals, w...
Considering the size of some nuclei and area, sex hormones control the sexual development of the brain. The sexual development of the brain can also be influenced by environmental stress. This study aimed to clear the effect of prenatal water deprivation on the development of sexual dimorphic nucleus (SD...
