Polychlorinated biphenyls (PCBs) are persistent environmental pollutants that can severely disrupt the synthesis and secretion of endocrine hormones. To investigate the effects of 2,3',4,4',5-pentachlorobiphenyl (PCB118) on thyroid structure and function, 40 male Wistar rats were divided into 4

The maize (Zea mays) spikelet consists of two florets, each of which contains three developmentally synchronized anthers. Morphologically, the anthers in the upper and lower florets proceed through apparently similar developmental programs. To test for global differences in gene expression and to

BACKGROUND Since long high fat diet (HFD) is being blamed for causing fatty degeneration of liver and formation of atheromatous plaques. At present, no proper pharmacotherapy is available for both the conditions. In this study, different substances containing monounsaturated fatty acids were used to

The scrota of three Pony stallions and one miniature horse were insulated for 36 h. Plasma testosterone concentrations decreased gradually and were significantly (P < 0.05) lower than pretreatment values at 16, 24, 30, 38 and 44 h after onset of scrotal insulation. Plasma LH and oestradiol

Neonatal exposure to soy isoflavones at levels similar to that of infants fed soy protein formula resulted in higher bone mineral density (BMD), improved bone structure, and greater bone strength at young adulthood in female CD-1 mice (1,2). Our objective in this study was to determine whether these

The occurrence of Bacillus and Paenibacillus spores in silage is of great concern to dairy producers because their spores can survive pasteurization and some strains are capable of subsequently germinating and growing under refrigerated conditions in pasteurized milk. The objectives of this study

Hexachlorobenzene (HCB) was administered to female Sprague-Dawley rats in a 13-week toxicity study conducted for the National Toxicology Program (NTP). Groups of 10 rats were treated by gavage with 0.0, 0.03, 0.1, 0.3, 1.0, 3.0, 10, or 25 mg/kg HCB in corn oil 5 days/week for 13 weeks.

OBJECTIVE To measure the macular pigment optical density (MPOD) in healthy Chinese people and patients with early age-related macular degeneration (AMD). METHODS Cross-sectional population based study. Demographic and lifestyle characteristics were ascertained by questionnaire. A food frequency

Adult female F-344 rats were trained (avoidance rate > 70%) over four days with a coupled tone- (n = 10 rats/dose) or 2 ppm acetaldehyde-cued (n = 6 rats/dose) foot shock paradigm. Rats were gavaged with chloroform dissolved in corn oil for 5 days/week for 3 week at 0 or 400 (tone-cued) or 0, 34,

Destruction of mouse oocytes in primordial and small primary follicles in response to treatment with 3-methylcholanthrene (MC) was studied at the ultrastructural level. Four-week old C57Bl/6N (B6) strain mice received a single injection of 80 mg/Kg MC in corn oil intraperitoneally. Controls received

In flowering plants, the tapetum is proposed to play a vital role in the early stages of pollen development. Disruptions to tapetum development and degeneration typically result in male sterility. The present study characterised a maize (Zea mays L.) anther-specific gene, Zm401, which only contains

Storage stability of health-food and conventional vegetable oils was evaluated by determining oxidative deterioration during accelerated storage at 60 C of unused oils and room-temperature storage of unused and used (once-heated) oils. Oxidative changes were determined by peroxide value (PV),

Prenatal exposure to the herbicide linuron, a weak androgen receptor antagonist, has been shown to perturb androgen-dependent male rat reproductive development as evidenced by slight decreases in anogenital distance (AGD), increased retention of areolae/nipples, and induction of epididymal

Reduced muscle activity leads to impaired insulin signaling, which leads to loss of contractile proteins and muscle mass via the Akt pathway. Dietary fish oil rich in long chain n-3 polyunsaturated fatty acids has been shown to prevent insulin signaling resistance in skeletal muscle. This study was

The protective effect of vitamin A and vitamin E succinate against 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced acute toxicity and measures of oxidative stress was studied. Ten mice were treated with either vitamin A (50 mg/kg every other day for eight days) or vitamin E succiante (150
