BACKGROUND High dietary intake of selenium or isoflavones reduces risk factors for prostate cancer. We tested whether combined supplementation of these two dietary components would reduce prostate cancer risk factors in rats more than supplementation of each component individually. METHODS Male Noble rat pups were exposed from conception to diets containing an adequate (0.33-0.45 mg/kg diet) ...

Several in vitro studies have showed the neurotoxic effect of homocysteine (Hcy) to various neuronal types, including cerebellar Purkinje neurons. In this study, we investigated whether the Hcy has neurotoxic effects on the rat pup’s cerebellum in the postnatal period that it continues to development. Pups rats divided into control and Hcy group. Hcy administration (0.3–0.6 mmol/g b...

Loss of water through the immature skin can lead to hypothermia and dehydration in preterm infants. The water and glycerol channel aquaglyceroporin-3 (AQP3) is abundant in fetal epidermis and might influence epidermal water handling and transepidermal water flux around birth. To investigate the role of AQP3 in immature skin, we measured in vivo transepidermal water transport and AQP3 expression...

INTRODUCTION Electromagnetic fields (EMF) have adverse effects as a result of widespread use of electromagnetic energy on biological systems. The aim of this study was to investigate the effects of prenatal exposure to EMF on rat myocardium by biochemical and histopathological evaluations. MATERIAL AND METHODS In this study, 10 pregnant Wistar rats were used. Half of the pregnant rats were ex...

Neonatal hypoxic ischemic encephalopathy (HIE) has been reported to induce apoptosis in neonates. We, therefore, analyzed the ability of Bax-inhibiting peptide (BIP) to provide neuroprotective effects during hypoxic-ischemic brain damage (HIBD). Seven-day-old wistar rat pups (n = 198) were randomly divided into a sham-operated group (Group S, n = 18), saline group (Group C, n = 90) and BIP grou...

Early in ontogeny, young rats must be able to detect dangerous stimuli and to exhibit appropriate defensive behaviors. Different nuclei of the amygdala mediate unconditioned and conditioned fear responses to threat in adult rats. The aim of this study was to determine the role of the amygdala in unlearned fear behavior in young rats. When exposed to an unfamiliar adult male rat, preweaning rat ...
