Single nephron structure and function, and renal effects of catecholamines in the dogfish, Scyliorhinus canicula
… 6. Plasma levels of the catecholamines adrenaline, noradrenaline and dopamine were determined in resting fishes, and following stress induced by MS222 (Tricaine methane sulphonate) anaesthesia and surgery. 7. Infusion of adrenaline increased systolic and diastolic systemic blood pressure …

Cardiac arrest in children preceding PICU admission: Aetiology and outcome in a developing country
… minutes. Thirty-five (34%) patients received no adrenaline, 44 (42.7%) received up to 3 doses of adrenaline, and 24 (23.3%) received more than 3 doses of adrenaline during resuscitation. Duration of CPR and number of adrenaline doses did not significantly influence patient outcome. Survival to …

The role of thyroid and steroid hormones in maturation of the adreline-sensitive reabsorptive mechanism of the fetal lung
… (term = 147 days) prevented the development of adrenaline- or cyclic AMP-sensitivity which, in euthyroid fetuses, resulted in the capacity to absorb lung liquid from 130 days onwards. Studies in which T₃ and T₄ were infused to thyroidectornized fetal sheep showed that T₃ was required for the …

Regulation of glucagon secretion from pancreatic alpha cells
… by low concentrations of cyclic AMP (cAMP). Adrenaline also acts on α-cells by cAMP-dependent mechanisms. However, unlike GLP-1, adrenaline stimulates glucagon secretion. This is because α-cells contain 100- to 1000-fold more β-adrenoreceptors than GLP-1 receptors. Exposure to adrenaline can …

Testing metabolic and pharmacological agents for recovery following de novo acute heart failure in an isolated rat heart model
… high albumin-bound free fatty acids (1.3mM) (±adrenaline 10-M) were added in theperfusate. Molecular and metabolic agents were administered either alone or in combination in the acute heart failure or recovery phases. Effects of glucose, insulin and sphingosine-1-phosphatewere observed on heart …

Catecholamine physiology in the sheep
… 90 minute infusions of 1-dopa, dopamine, noradrenaline and adrenaline. A 2-compartmental pharmacokinetic model of 1-dopa plasma dynamics was constructed and the half-lives of the fast and slow decay curves determined. Estimation of the half-lives of dopamine, noradrenaline and adrenaline was …

The welfare and quality of farmed salmonids at harvest.
… Differences were not detected in plasma noradrenaline levels in cither species. The death in ice slurry trout appeared to exhibit the lowest stress response with the least adrenaline and cortisol: it was hypothesised that reduced neural responses due to the low body temperature of these fish …

Microdialysis to study the Gastrin-ECL cell Axis in the conscious rat
… submucosal microinfusion of endothelin and adrenaline induced massive release of histamine and caused severe local damage to the mucosa. The results of the present study indicate that ECL cells are the source of the histamine and that endothelin and adrenaline affect ECL cells in situ in an …

The relationship between boron, stress hormones and bone markers in humans of different ages, life style and health status
… coupled plasma spectrophotometry and cortisol, adrenaline, dopamine and serotonin by high performance liquid chromatography. Information about each subject's life style, nutrition and health was obtained using a questionnaire. Data were processed and analysed using excel and minitab packages and …

The influence of pre- and post-mortem treatments of glycogen content and tenderness of poultry muscles
… included fasting, full-feeding, subcutaneous adrenaline injection, and oral administration of ethyl alcohol. The effect of stretch-tension during rigor on muscle tenderness was also studied. Ante- and post-mortem treatments of the broilers had significant effects upon the rigor patterns, …

The effects of early life nutrient restriction on the cardiovascular system of the adult sheep
… combined with a postnatal challenge (UU). Basal adrenaline was elevated in male and female singletons exposed to the postnatal challenge (CU & UU). The stressor produced an enhanced adrenaline response in the females in the postnatally challenged group (CU). This effect was attenuated when …

Despite evidence that these five therapies and management processes have no benefit, variation in clinical practice occurs with infants receiving non-evidence-based and potentially harmful care. The purpose …

Adiponectin : a novel circulating anti-thrombotic factor in humans?
… through the P2Y12 coupled Gi receptor and by adrenaline acting through the Gz-linked α2A adrenoceptor. Further examination of this pathway revealed that the activation of phosphatidyl-inositol-3-kinase (PI3K) was required to restore secretion. To clarify the role of PI3K in this process we …
