" the Neuroendocrine Control of Broodiness
The neuroendocrine control of broodiness was investigated in the bantam hen. The functional activity of hypothalamic monoaminergic neurones and the role of vasoactive intestinal polypeptide were considered in relation to the control of prolactin and luteinizing hormone (LH) secretion. The functional activity of hypothalamic noradrenergic neurones, based on an index of turnover, did not change a...
متن کاملTranscriptome Profiling of the Goose (Anser cygnoides) Ovaries Identify Laying and Broodiness Phenotypes
BACKGROUND The geese have strong broodiness and poor egg performance. These characteristics are the key issues that hinder the goose industry development. Yet little is known about the mechanisms responsible for follicle development due to lack of genomic resources. Hence, studies based on high-throughput sequencing technologies are needed to produce a comprehensive and integrated genomic resou...
متن کاملPolymorphisms of vasoactive intestinal peptide receptor-1 gene and their genetic effects on broodiness in chickens.
Broodiness is a polygenic trait controlled by a small number of autosomal genes. Vasoactive intestinal peptide receptor-1 (VIPR-1) gene could be a candidate of chicken broodiness, and its genomic variations and genetic effects on chicken broodiness traits were analyzed in this study. The partial cloning and sequencing of the VIPR-1 gene showed that the average nucleotide diversity was 0.00669 +...
متن کاملMyocardial ischemia and viability
This paper addresses the question of whether and how MCG tests that assess ischemia or viability of the myocardium can add to the diagnostic information gained from standard procedures in asymptomatic and symptomatic patients. We review the diagnostic performance of the exercise electrocardiogram (ECG), the exercise and pharmacological (stress) echocardiogram, the exercise and pharmacological m...
متن کاملViability, Remodeling, and CABG
F ollowing myocardial infarction, left ventricular (LV) remodeling is characterized by increased LV end-diastolic and end-systolic volumes (ESV) and decreased LV ejection fraction (EF) (1). This process is driven by elongation of infarcted zones and changes within the unaffected myocardium, including myocyte hypertrophy and interstitial collagen deposition. With medical therapy, revascularizati...
