Adult obese (fa/fa) Zucker rats hypersecrete insulin in response to glucose and other secretagogues. Functional changes in islet alpha 2-adrenoceptors (8) and glycolytic regulation (9) have been reported. In this study, the development of these biochemical lesions in islets isolated from suckling (3...

Adrenalectomy prevents development of obesity and hyperinsulinaemia in obese (fa/fa) Zucker rats, thereby implicating the hypothalamo- pituitary-adrenal axis in the pathogenesis of obesity. In this study glucose-induced insulin secretion and glucokinase activity were investigated in isolated islets ...

Our objective was to determine if a cafeteria-type diet with increased fat content would block the decrease in insulin secretion induced by adrenalectomy in obese rats. Five week old Zucker (fa/fa) rats were adrenalectomized. One week later, half of the adrenalectomized groups, and age-matched, sham...

In this study the glucose responsiveness of isolated, overnight-cultured islets of obese LA/N-corpulent (cp/cp) rats was compared with glucose phosphorylating activity to determine whether changes in the function of glucokinase could be identified. Islets from both male and female cp/cp rats showed ...

The objectives of this study were to document the effects of moderate aerobic exercise on insulin secretion and other metabolic indices in fa/fa rats and to determine if a high-fat (HF) diet altered these effects. Six-week-old fa/fa and lean Zucker rats were either sedentary or exercised by daily sw...

Farmed fish provide an increasing fraction of the human food supply, and are of major economic importance in many countries. As in the case of terrestrial agriculture, bringing together large numbers of animals of a single species (i.e., monoculture) increases the risk of infectious disease outbreak...

Abstact: Infectious salmon anaemia (ISA) is a serious disease of marine-farmed Atlantic salmon (Salmo salar) caused by ISA virus (ISAV), which belongs to the genus Isavirus, family Orthomyxoviridae. ISA is caused by virulent ISAV strains with deletions in a highly polymorphic region (HPR) of the hem...

Infectious salmon anaemia (ISA) virus (ISAV) is a fish orthomyxovirus that has recently been assigned to the new genus Isavirus within the family Orthomyxoviridae. It possesses the major functional characteristics of the virus family including haemagglutinating, receptor destroying enzyme (RDE), and...

Infectious salmon anaemia virus (ISAV), an orthomyxovirus-like virus, is an important fish pathogen in marine aquaculture. Virus neutralization of 24 ISAV isolates in the TO cell line using rabbit antisera to the whole virus and comparative sequence analysis of their haemagglutinin (HA) genes have a...

Infectious salmon anemia (ISA) virus (ISAV), an economically important new pathogen in marine aquaculture, is classified in the family Orthomyxoviridae, genus Isavirus. The main structural properties of this genus include enveloped virions 90-140 nm in diameter with surface projections of a combined...
