Objective- To determine the effects of growth hormone (GH) therapy on bone density in controlled conditions in healthy adult rabbits. Design- Experimental in vivo study.  Animal- 20 healthy, adult New Zealand White rabbits. Procedures- The rabbits were divided into 2 groups; receiving Human GH (0.006 mg/kg/d) and controls; receiving placebo for 3 months. The density of radius and tibia was m...

Records of Holstein cows were used to examine how different models account for the effect of bovine somatotropin (bST) treatment on genetic evaluation of dairy sires for yield traits and somatic cell score. Data set 1 included 65,720 first-lactation records. Set 2 included 50,644 second-lactation records. Set 3 included 45,505 records for lactations three, four and five. Estimated breeding valu...

In this study Escherichia coli DE3 containing expression vector (pET21a) with cloned Persian sturgeon growth hormone (psGH) gene was grown in 10 mL LB broth on a 150 rpm shaker, at the temperature of 37 °C. At the late log phase (determined by OD standard curve) 100 &muL isopropyl &beta-D-1-thiogalactopyranoside (IPTG) was added for induction of GH synthesis. Samples were taken every 2 hours an...

Records from Dairy Records Management Systems in Raleigh were used to estimate effects of bovine somatotropin (bST) treatment and to predict breeding values for milk production traits. The data comprised 5245 test-day records of bST-treated cows and 126,223 test-day records of untreated cows in first lactation for milk, fat, and protein yields. Fixed effects of bST treatment were estimated from...

Although clinical and experimental evidence had previously indicated that skeletal growth depended upon the pituitary gland, it was not until I92I that Evans and Long, at the University of California, demonstrated that a saline emulsion made from the anterior pituitary lobe of fresh glands of cattle contained a growth hormone. The hypophyses were thrown into 40 per cent. ethyl alcohol, agitated...

background: b-thalassemia major is a serious medical problem. growth retardation is commonly seen in poly-transfused b- thalassemia patients. the exact mechanism of short stature in children with thalassemia major is not well understood, however, it is believed to be multi-factorial. objective: to study the growth state and its relationship to growth hormone (gh) deficiency in b-thalassemia pat...

OBJECTIVE Recent studies have challenged the traditional paradigm that growth hormone receptor (GHR) displays physiological functions only in the cell membrane. It has been demonstrated that GHR localizes to the cell nucleus and still exhibits important physiological roles. The phenomenon of nuclear localization of growth hormone (GH)-induced GHR has previously been described in vitro. However,...
