Steroid sulphatase (STS) is the primary enzyme for desulphating steroids from their inactive to their active forms. Principal substrates include steroid precursors oestrone-sulphate and dehydroepiandrosterone sulfate. Alterations in STS activity can directly affect local concentrations of oestradiol, testosterone and dihydrotestosterone; steroids that are frequently dysregulated in disease. Despite the importance of STS activity on steroid synthesis, little is known about its ...

The increasing global prevalence of obesity requires urgent intervention to limit the anticipated surge of associated cardiometabolic morbidity and mortality. The energy sensor AMP-activated protein kinase (AMPK) is one proposed target for treating metabolic disorders and is downregulated in adipose tissue of obese insulin resistant individuals. Given the strong relationship between metabolic syndrome and overactivity of the renin-angiotensin-aldosterone system (RAAS) we inves...

The medical burden of deprived patients is high. In diabetes deprivation status is associated with poor metabolic control and more frequent complications. No data to date existed showing the association between individual deprivation in adults and anthropomorphic factors linked to abdominal obesity. We would determine whether individual index of deprivation were associated with anthropomorphometric dimensions, postures or body girths and metabolic parameters. We conducted a cr...

Calcium is important for physiological functioning in many tissues and is essential in mucus secretion and muscle contraction. Intracellular concentrations of calcium are regulated by calcium-related proteins such as TRPV4, TRPV6, CaBP-9k, NCX1, and PMCA1. In this study, the relationship between secretion of pulmonary mucus and calcium regulation was investigated. To confirm the effect of steroid hormones, immature mice were injected with estrogen (E2) or progesterone (P4) and...

BackgroundPrimary aldosteronism (PA) affects 5-20% of all patients with hypertension, and is likely the most common treatable cause of hypertension. Patients with PA have higher risk of cardiovascular disease, atrial fibrillation and stroke. We aimed to estimate the prevalence of PA in patients with recent stroke.MethodsWe prospectively recruited 300 patients who were admitted to the acute stroke unit of a si...

Background: The hypothalamus-pituitary-adrenal axis (HPA) controls the neuroendocrine response to psychological and physiological stress. The balance of the hormones synthesised and secreted by these organs is tightly regulated. However, there are intrinsic differences in the relative expression of these hormones depending on sex, which can influence the magnitude of the endocrine response to stressors or the response to pharmacological treatments. Herein, we ...

Background & Aims: NutriAct is a 36-month randomized controlled multi-center trial aiming to analyze the effects of a dietary pattern focusing on a high-protein and high-unsaturated fatty acids (UFA) intake on healthy aging. We aimed to explore changes in intake of macronutrients and determine factors associated with a successful modulation of dietary pattern after 36 months in elderly community dwelling participants.Methods: 502 participants were ra...

Introduction: The growth of human tumors depends on the formation of new blood vessels and vascular endothelial growth factor (VEGF) helps control this process via inducing new capillaries to sprout from pre-existing blood vessels. Four cardiac hormones which eliminate up to 80% of human pancreatic cancers and up to 86% of human small-cell lung cancers growing in mice were investigated for their effects on VEGF and the VEGFR2/KDR/Flk-1 receptor. The VEGFR2 receptor is the main...
