Fast-twitch skeletal muscles are specialized for in vivo motor functions that require high power (mastication and load lifting), high speed (eyelid blink), or a combination of the two (withdrawal reflexes and escape responses). Those functions that rely on high power often involve tetanic stimulation of the effector muscles, resulting in sustained force generation even during tetani that are no...

OBJECTIVES To determine the safety and efficacy of oral bexarotene (Targretin capsules; Ligand Pharmaceuticals Incorporated, San Diego, Calif). DESIGN The effects of 2 randomized doses of 6.5 mg/m(2) per day (with crossover for progression) vs 650 mg/m(2) per day (later modified to 300 mg/m(2) per day) were evaluated in an open-label, multicenter, phase 2 and 3 study conducted between Februar...

Toxicological evaluation of fucoidan extracted from Laminaria japonica in Wistar rats. Food Chem Toxicol. 2005 Mar;43(3):421-6. However, there is no detailed report investigating the toxicity of fucoidan. In this study, the acute and subchronic (6 months) toxicity of varying levels of fucoidan extracted from Laminaria japonica was investigated in Wistar rats after oral administration. The resul...

This study explored the effects of GnRH agonist (GnRHa) immunity on expression of FSHR mRNA in pituitary and FSHR protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (EG) during anestrus season. Animals in EG-I, EG-II and EG-III were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

Feathers may be problematic to chickens in thermoregulation during heat stress. This study was conducted to investigate the effect of clipping feathers, dietary ascorbic acid supplementation and season on performance of laying chickens. 180 ‘Isa Brown’ (IB) layers of about 30 weeks old were subjected to a 2×2×2 factorial combination of feather conditions (intact and clipping), dietary ascorbic ...

the objective of this study was to determine the effects of two different time of gnrh injection after artificial insemination (a.i) (d 6 and d 12) on reproductive performances of holstein cows during the warm season.  cows randomly assigned to treatments 1) no gnrh injection (control, n = 300),2) gnrh injection at day 6 after a.i (g6, n=300) and 3) gnrh injection at day 12 after a.i (g12, n=30...

BACKGROUND During the last decades, environmental contamination by lead generated from human activities has become an evident concern. The present study assessed the long-term effects of neonatal exposure to different doses of lead acetate on the ovaries of offspring rats. MATERIALS AND METHODS Pregnant female Wistar rats were randomly divided into a control and three experimental groups. The...

BACKGROUND Adrenal insufficiency is a complication of transsphenoidal surgery (TSS) for pituitary adenoma, and correct identification of patients requiring glucocorticoid replacement is important. Controversy exists over which early postoperative 9 AM cortisol concentration reliably predicts hypothalamic-pituitary-adrenal (HPA) axis reserve, as defined by the insulin tolerance test (ITT). MET...

this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...
