Maintenance requirement for lysine by mature female rats
Fifty twelve-month female Sprague-Dawley rats were used to study a lysine requirement for tissue maintenance. Animals were randomly assigned into five groups with dietary lysine levels ranging from 0.097 to 0.317 percent and fed for 60 days. Liver composition and carcass composition were …

Maintenance protein requirement of twelve month old female rats
Ninety 12 month old female rats were used to determine a protein requirement for tissue maintenance. Diets contained 0.84 to 4.69 percent protein and were fed for 28 days. Liver composition, carcass composition and serum protein levels were determined, and a protein requirement level was also …

The effects of exercise on iron metabolism in adult female rats
… and iron intake on iron metabolism in adult female rats were investigated. Adult female Sprague-Dawley rats were assigned to either an exercise (E) or sedentary (S) group and fed either a diet containing 9 ppm (9) of dietary iron (low iron level), or 40 ppm (40) of iron (a level slightly …

Adversity in early adolescence alters female rats' anxiety-related behaviours and serotonergic innervation profiles in adulthood
… (PD 22-33) on anxiety-related behaviour of female rats was analyzed in adulthood. After behavioural testing, serotonergic innervation was evaluated using immunohistochemistry for the serotonin transporter (SERT) in the medial prefrontal cortex (mPFC) and ventral hippocampus. Administration …

The effects of exercise and dietary iron on iron status in 13 months old female rats
… components of iron metabolism in 13 month old female rats. Fifty-six 13 month old female Sprague-Dawley rats were randomly assigned to one of five groups of treatment: baseline (BL); 40ppm iron, exercise (40 E); 9ppm iron, exercise (9 E); 40ppm iron, non- exercise (40 NE); 9ppm iron, …

Neonatal exposure to estradiol in female rats influences neuroactive steroid concentrations and behaviour in the adult rat
… of nervous system. Exposure of the developing female to estrogens during perinatal period may have long-lasting effects that are now regarded as “programming” the female neuroendocrine axis to malfunction in adulthood. The purpose of this study was to describe the effect of a single …

Locomotor sensitization and conditioned place preference for amphetamine in late adolescent and adult male and female rats /
… are not due to gonadal immaturity, as females are cycling at this stage of adolescence. However, age differences may reflect the ongoing maturation of the neural substrates that that are involved in locomotor sensitizing, but not rewarding effects of amphetamine.

Acute Effects of Episodic PCB Congeners on the Hypothalamo -Pituitary-Thyroid (Hpt) Axis in Weanling Female Rats
These studies demonstrate that brief exposure to ortho-substituted PCBs can cause alterations in the HPT axis in immature animals. The data indicate that ortho-PCBs 95 or 101 cause secondary or pituitary-related hypothyroidism. There is also evidence that these PCBs may be affecting the HPT-axis …

The effects of exercise and dietary iron on iron status in 19 month old adult female rats
… and dietary iron on iron status in 19-month-old female rats. Fifty-seven female Sprague-Dawley rats were randomly assigned to one of five experimental groups: baseline (BL); iron sufficient-exercise (HE); iron sufficient-sedentary (HS); moderate iron deficient- exercise (LE) and moderate iron …

THE EFFECT OF MELATONIN IN PROTECTING AGAINST THE BEHAVIORAL CONSEQUENCES OF CHRONIC HYPOPERFUSION IN MIDDLE-AGED FEMALE RATS
… use of the 2-vessel occlusion (2VO) procedure in rats, which limits cerebral blood flow (CBF) through bilateral arterial ligation. Therefore, the current study investigated whether chronic melatonin would attenuate 2VO induced behavioral deficits in middle-aged female rats. Thirty 9- to …

Impact of Prenatal Alcohol Exposure on Cognition and Inflammation in Aging Male and Female Rats: A Longitudinal Approach
… dysregulation, and neuroinflammation in aging rats with a focus on sex-specific differences. Using a well-established rat model of PAE, spatial learning and memory, recognition memory, serum cytokine levels and Iba-1 cell expression in the dentate gyrus (DG) were assessed at two different time …

Developmental Cell Death and Androgens Affect Neuron Number in the Primary Visual Cortex of Male and Female Rats
… the effect of neonatal hormone manipulations (females + estradiol, females + DHT) upon cell death in the developing rat posterior cortex. DHT implantation in females decreased the proportion of cells dying relative to control females (similar to control males), while estrogen implantation in …

Effects of polychlorinated biphenyls (PCBs) on hepatic enzyme induction, uterotropic responses, and thyroid hormone levels in prepubertal female rats
A 2-day short-term bioassay, using prepubertal female Sprague-Dawley rats, was developed to study effects of polychlorinated biphenyls (PCBs) on hepatic enzyme induction, uterotropic responses, and thyroid hormone levels. Three approaches have been used to study the multiple effects of PCB …

The Effects of Neonatal Immune System Activation with Lipopolysaccharide on Adolescent and Adult Anxiety Behaviours in Male and Female Rats
The present study examined the effects of neonatal (postnatal days 3 and 5) acute immune system activation with lipopolysaccharide (LPS) on adolescent and adult anxiety behaviours. The major findings suggest that neonatal LPS does not have general long-lasting effects on adolescent anxiety and …
