Central administration of dipeptides, beta-alanyl-BCAAs, induces hyperactivity in chicks
(2007-05-31)Background Carnosine (β-alanyl-L-histidine) is a putative neurotransmitter and has a possible role in neuron-glia cell interactions. Previously, we reported that carnosine induced hyperactivity in chicks when intracereb ... -
Growth hormone stimulates hepatic expression of bovine growth hormone receptor messenger ribonucleic acid through signal transducer and activator of transcription 5 activation of a major growth hormone receptor gene promoter
(Endocrine Society, 2007-07)The objective of this study was to determine whether and how GH regulates hepatic expression of GH receptor (GHR) mRNA in cattle. Ribonuclease protection assays revealed that injection of GH in a slow-release formula ... -
Phenotypic evolution from genetic polymorphisms in a radial network architecture
(2007-11-14)Background The genetic architecture of a quantitative trait influences the phenotypic response to natural or artificial selection. One of the main objectives of genetic mapping studies is to identify the genetic factors ... -

Growth hormone regulation of insulin-like growth factor-I gene expression may be mediated by multiple distal signal transducer and activator of transcription 5 binding sites
(Endocrine Society, 2008-05)The transcription factor signal transducer and activator of transcription (STAT)-5 mediates GH stimulation of IGF-I gene expression in the liver. Previous studies suggested that STAT5 might exert this effect by binding to ... -
Cytokine mRNA Expression in the Small Intestine of Weanling Pigs Fed Diets Supplemented with Specialized Protein or Peptide Sources
(2008-12)Cytokines play a central role in the mucosal immune response and are involved in regulation of nutrient absorption, metabolism and animal growth This study investigated the effect of diet manipulation with specialized ... -

Sheep Management Schedule
(Virginia Cooperative Extension, 2009)Profitable sheep production requires the application of certain well-timed management practices to ensure the overall well-being of the flock. -
Newborn Lamb Management
(Virginia Cooperative Extension, 2009)The three primary causes of death of newborn lambs are difficulty during the birthing process, starvation and hypothermia. Solid management practices at lambing time are essential. -
Effects of Feeding Different Protein Supplements on Digestibility, Nitrogen Balance and Calcium and Phosphorus Utilization in Sheep
(2009-05)Two metabolism trials were conducted with 24 wether lambs to investigate the effects of feeding crab meal and other protein supplements on N utilization, digestibility and Ca and P balance in sheep. The lambs (avg. BW, 25 ... -
Genetic analysis of an F2 intercross between two chicken lines divergently selected for body-weight
(2009-05-27)Background We have performed Quantitative Trait Loci (QTL) analysis of an F2 intercross between two chicken lines divergently selected for juvenile body-weight. In a previous study 13 identified loci with effects on ... -
Proviral integrations and expression of endogenous Avian leukosis virus during long term selection for high and low body weight in two chicken lines
(2009-07-15)Background Long-term selection (> 45 generations) for low or high juvenile body weight from a common founder population of White Plymouth Rock chickens has generated two extremely divergent lines, the LWS and HWS lines. ... -
Temperature-Change-Based Thermal Tomography
(Hindawi, 2009-07-22)Thermal properties of biological tissues play a critical role in the study of tumor angiogenesis and the design and monitoring of thermal therapies. To map thermal parameters noninvasively, we propose temperature-change-based ... -

Growth Hormone-Activated STAT5 May Indirectly Stimulate IGF-I Gene Transcription through HNF-3 gamma
(Endocrine Society, 2009-12)IGF-I is abundantly expressed in the liver under the stimulation of GH. We showed previously that expression of hepatocyte nuclear factor (HNF)-3 gamma, a liver-enriched transcription factor, was strongly stimulated by GH ... -
