paraneoplastic syndromes result from secretion of hormones, peptides or cytokines by tumor or immune cross-reactivity between malignant and normal tissues. these conditions are rare in children, but when the clinical presentation of patients with a tumor is unusual, these syndromes should be emphasized . extrarenal tumors with renin-secretion are rare in children. they may be related to paraneo...

- pseudohypoaldosteronism (p'ha) is referred to a state of endorgan unresponsiveness to aldosterone. in this article a 12 day - old mule newborn is presented with hyponatremia, hyperkalemia and metabolic acidosis. aldosterone level and plasma renin activity were high. mineralocorticoids had no therapeutic effect, hut normal saline infusion improved electrolyte imbalance. salt-rich diet was succ...

The renin–angiotensin–aldosterone system is the well established endocrine system having significant role in preserving hemodynamic stability. Renin is secreted from the juxtaglomerular cells of the kidney. Phenylpiperazine derivatives have been reported as human renin inhibitor. To perform predictive QSAR modeling for 27 phenylpiperazine derivatives as renin enzyme inhibitors. The IC50 values ...

      In this study, the changes of renin system activity and the effects of aspirin therapy on the plasma renin activity ( PRA) in myocardial infarction were investigated. Fifty nine patients with myocardial infarction were selected. By suppressed in the former group which was statistically significant ( p<0.01).   

the renin-angiotensin-aldosterone system (raas) plays pivotal roles in the pathogenesis of chronic kidney disease (ckd) progression and its increased complications such as hypertension (ht) and cardiovascular diseases (cvd). previous studies suggested that aliskiren a direct renin inhibitor, blocks raas and may be effective for the management of ckd and its complications. this review focuses on...

conclusions garlic powder consumption can reduce blood pressure, yet in this model, it did not have an effect on the interaction between renin angiotensin system and nitric oxide inhibition. results at the beginning and at the end of experiments, systolic blood pressure was higher in the hypertensive groups than the normotensive group. however, at the end of the study, diastolic blood pressure ...

(Pro)renin receptor (PRR) is the recently discovered component of renin-angiotensin-aldosterone system (RAS). Many organs contain their own RAS, wherein PRR can exert organ-specific localized effects. The Binding prorenin/renin to activates angiotensin-dependent and independent pathways which leads development physiological pathological Continued progress in research suggests that upregulation ...

The important renal endocrine aspect implicated in gym nephropathy is the activation of renin-angiotensin-aldosterone system (RAAS). Intense exercise can lead to increased sympathetic nervous activity, resulting release renin from juxtaglomerular cells kidneys. Renin acts on angiotensinogen, leading generation angiotensin II, a potent vasoconstrictor. Angiotensin II stimulates secretion aldoste...
