The kidney's responsiveness to male sexual hormones has been often neglected. Renal secretion of organic anions is higher in male than in female individuals; as a consequence, most of the xenobiotics that are excreted from the organism through this pathway are eliminated more rapidly by males than by female animals. To gain further insight into this issue, we studied in vitro and in vivo charac...

BACKGROUND Malachite green chloride is a dye used to prevent fungus infections in commercial fisheries. Leucomalachite green is formed from malachite green and remains in the tissues of exposed fish. We studied the effects of malachite green on female rats and female mice, and the effects of leucomalachite green on male and female rats and female mice, to identify potential toxic or cancer-rela...

Although Hatano high-avoidance and low-avoidance rats (HAA and LAA, respectively) have been selectively bred for good versus poor avoidance learning, HAA rats are known to be more reactive to stress than LAA rats. In this study, HAA and LAA female rats were compared during reproductive aging by observing estrous cycles from 8 to 11 months of age. Furthermore, these rats were allowed to live out...

The relationship between the microbiota profile and exposure to stress is not well understood. Therefore, we used a rat model of unpredictable chronic mild (UCMS) investigate this relationship. Depressive-like behaviors were measured in Female Sprague Dawley rats using sucrose preference test Porsolt swim test. Anxiety-like with light–dark box Fecal corticosterone, cecal (composition organic ac...

Age and the estrus cycle affect time-dependent respiratory responses to episodic hypoxia in female rats. Respiratory long-term facilitation (LTF) is enhanced in middle-aged vs. young female rats (72). We tested the hypothesis that phrenic and hypoglossal (XII) LTF are diminished in acyclic geriatric rats when fluctuating sex hormone levels no longer establish conditions that enhance LTF. Chroni...

Introduction: For some cancer survivors chemotherapy treatment is associated with lasting motor and cognitive impairments, long after treatment cessation. Cisplatin as an anti-neoplastic agent is extremely toxic and can cause severe tissue damage. In the present study, we elucidated alteration in performance of hippocampus- and cerebellum-related behaviors following acute cisplatin treatmen...

To investigate effects of high-fat diet (HFD) on body length, weight and depression-like behavior prenatal stress (PS) offspring rats. PS rat model was established by restraint stress. Sucrose preference forced swimming tests were performed. Moreover, the HFD growth in rats observed. Length male female HF group significantly longer than that control, but length PS+HF shorter group. Body higher ...

Fetal growth restriction can affect health outcomes in postnatal life. This study tested the hypothesis that response to an inflammatory pulmonary insult is altered pediatric fetal restricted rats. Using a low-protein diet during gestation and life, growth-restricted male female rats healthy control were exposed via intratracheal instillation of heat-killed bacteria. After 6 h, animal lungs exa...

Affective disorders are more common in women. The forced swim test acts like a depressive stimulus. Hippocampus and frontal cortex 5-HT1A receptors of female and male Wistar rats subjected to the forced swim test were compared with a sham group. The forced swim test diminishes (P<0.05) the hippocampus 3H-8OH-DPAT bound in the female rats (184+/-16 fmol/mg protein) with respect to the male rats ...
