The aim of this study was to evaluate the association between thyroid hormone levels, pulmonary hypertension (PH), and pulmonary artery systolic pressure (PASP) in euthyroid patients with coronary artery disease (CAD). A cross-sectional study was conducted in individuals who underwent coronary angiography and were diagnosed as CAD from March 2013 to November 2013. 811 subjects (185 women and 626 men) were included in this study. PASP was measured by transthoracic Doppler echocardiography. 86 patients were diagnosed as PH and had significantly higher free thyroxine (FT4) levels than those without PH...

Data from animal experiments and clinical investigations suggest that components of the renin-angiotensin system are markedly affected by sex hormones. However, whether estrogen affects human atrial myocardium has not been investigated yet. In this study, we determined the effects of estrogen on key components of atrial renin-angiotensin system: angiotensin-converting enzyme, responsible for generation of angiotensin II and angiotensin-converting enzyme 2, counteracting majority of AngII effects, and different renin-angiotensin system receptors, AT1R, AT2R, and MAS...

BACKGROUND: The renin-angiotensin-aldosterone system (RAAS) regulates blood pressure, electrolyte homeostasis, and renal function. Blood pressure, serum sodium concentrations, and urinary albumin excretion are higher in Greyhounds than other purebred and mixed-breed dogs. HYPOTHESIS: Alterations in the RAAS in Greyhounds are associated with hemodynamic and clinicopathologic differences observed in the breed. ANIMALS: Clinically healthy Greyhound and non-Greyhound dogs consecutively enrolled as blood donors (n = 20/group)...

BACKGROUND: Attempts at the pharmacological treatment of Dupuytren's disease have so far been unsuccessful, and the disease is not yet fully understood on a cellular level. The Renin-Angiotensin System has long been understood to play a circulating hormonal role. However, there is much evidence showing Angiotensin II to play a local role in wound healing and fibrosis, with ACE inhibitors being widely used as an anti-fibrotic agent in renal and cardiac disease. METHODS: This study was designed to investigate the presence of Angiotensin II receptors 1 (AT1) and 2 (AT2) in Dupuytren's tissue to form a basis for further study into the pharmacological treatment of this condition...

Mineralocorticoid and glucocorticoid receptors are closely related steroid hormone receptors that regulate gene expression through many of the same hormone response elements. However, their transcriptional activities and effects in skeletal muscles are largely unknown. We recently identified mineralocorticoid receptors (MR) in skeletal muscles after finding that combined treatment with the angiotensin-converting enzyme inhibitor lisinopril and MR antagonist spironolactone was therapeutic in Duchenne muscular dystrophy mouse models...

Angiotensin-Converting Enzyme 2 (ACE2) is a key enzyme in the renin-angiotensin system (RAS), which is implicated in the pathogenesis of hypertension and other cardiovascular diseases. In this study we investigated the expression of ACE2 in the hypothalamus and pituitary tissues and its relationship to hypertension by comparing them in male WKY and SHR rats. We observed that the plasma levels of corticotrophin releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and aldosterone (ALD) were all lower in SHR than WKY rats (P<0...

Context: Overweight and obese children have an increased risk to develop cardiovascular diseases (CVDs) in which thyroid-stimulating hormone (TSH) has been suggested as an intermediary factor. However, results of cross-sectional studies are inconclusive, and intervention studies investigating changes in TSH concentrations in association with changes in cardiovascular risk parameters in overweight and obese children are scarce. Objective: To gain insight in associations of circulating TSH concentrations and cardiovascular risk parameters in overweight and obese children...

Cardiopathies and osteoporosis are inter-related due to pathogenetic, hormonal, genetic features as well as an increased risk of fragility. An important feature is attributed to the process of atherosclerosis, which is responsible for an osteopenia effect and degeneration of vascular walls. To date the study populations have been limited. To verify the incidence of cardio-vascular disease in a larger osteoporotic population, we designed a retrospective clinical study analyzing the “Hospital Discharge Data” (HDD) in Apulia between 2006 and 2010...

BACKGROUND: We conducted an exploratory analysis of osteoarthritis progression among medication users in the Osteoarthritis Initiative to identify interventions or pathways that may be associated with disease modification and therefore of interest for future clinical trials. METHODS: We used participants from the Osteoarthritis Initiative with annual medication inventory data between the baseline and 36-month follow-up visit (n = 2938). Consistent medication users were defined for each medication classification as a participant reporting at all four annual visits that they were regularly using an oral prescription medication at the time of the visit...

Sarcopenia of age is prevalent and costly and proven pharmacological interventions are currently lacking. The pathophysiology of sarcopenia is incompletely understood but appears to involve multiple pathways, including inflammation, hormonal dysregulation, impaired regeneration, mitochondrial dysfunction and denervation. There are several ways in which we might select potential pharmacological interventions for testing in clinical trials. These include a 'bottom-up' approach using basic science to elucidate the molecular processes involved and identify potential targets from this knowledge-a strategy that has led to the development of myostatin inhibitors...

Marty K S Wong, Yoshio Takei
The recent advance and revision on the renin-angiotensin system in lamprey were summarized and we emphasized that presence of two types of angiotensins (Angs) in lamprey. Due to the parasitic nature on fish blood, teleost-type Angs were produced in their buccal gland and secreted into the lamphredin to evade the host immunorejection. A native lamprey angiotensinogen (AGT) was identified in genome and it retains serine-protease inhibitor activity for thrombin that regulates the blood coagulation pathway. The native lamprey angiotensin II (Lp-Ang II) is hypotensive instead of hypertensive, suggesting a functional divergence on cardiovascular regulation from the main vertebrate groups...

The incidence of erectile dysfunction (ED) is on the increase and it is estimated that it will affect about 322 million men globally by the year 2025 if adequate measures are not taken to curb it. Natural polyphenols in plant based diets have gained public interest in recent times due to their roles in the prevention of various disease that implicate free radicals/reactive oxygen species and recently on ED. However, the role of polyphenols in the management of ED has not been explored due perhaps to limited data available...

Certain cancer therapies, including radiation therapy and some types of chemotherapies, are associated with increased risk of cardiovascular disease (CVD) and events. Some of these effects such as those presented by anthracyclines, radiation therapy, cisplatin, as well as those presented by hormone therapy for breast cancer-usually taken for many years for some breast and prostate cancers-are long-lasting and associated with cardiovascular events risk more than 20 years after cancer treatment. Cardiovascular testing, diagnostic assessment of suspected cardiovascular symptomatology, as well as laboratory tests for CVD risk factors are imperative...

BACKGROUND: Mid-regional pro-adrenomedullin (MR-proADM) is a surrogate marker for adrenomedullin; a hormone that attenuates myocardial remodeling. Accordingly, we hypothesized that MR-proADM could provide diagnostic and prognostic information in patients with acute dyspnea. METHODS AND RESULTS: We measured MR-proADM by a commercial ELISA on hospital admission in 311 patients with acute dyspnea and compared the utility of MR-proADM with N-terminal pro-B-type natriuretic peptide (NT-proBNP)...

BACKGROUND: The angiotensin-I converting enzyme (ACE) plays a central role in the renin-angiotensin system, acting by converting the hormone angiotensin-I to the active peptide angiotensin-II (Ang-II). More recently, ACE was shown to act as a receptor for Ang-II, and its expression level was demonstrated to be higher in melanoma cells compared to their normal counterparts. However, the function that ACE plays as an Ang-II receptor in melanoma cells has not been defined yet. AIM: Therefore, our aim was to examine the role of ACE in tumor cell proliferation and migration...

Hereditary angioedema with normal C1 esterase inhibitor and mutations in the F12 gene (HAE-FXII) is associated with skin swellings, abdominal pain attacks, and the risk of asphyxiation due to upper airway obstruction. It occurs nearly exclusively in women. We report our experience treating HAE-FXII with discontinuation of potential trigger factors and drug therapies. The study included 72 patients with HAE-FXII. Potential triggers included estrogen-containing oral contraceptives (eOC), hormonal replacement therapy, or angiotensin-converting enzyme inhibitors...

Angiotensin-converting enzyme inhibitors (ACEi) and mineralocorticoid receptor (MR) antagonists are FDA-approved drugs that inhibit the renin-angiotensin-aldosterone system (RAAS) and are used to treat heart failure. Combined treatment with the ACEi lisinopril and the nonspecific MR antagonist spironolactone surprisingly improves skeletal muscle, in addition to heart function and pathology in a Duchenne muscular dystrophy (DMD) mouse model. We recently demonstrated that MR is present in all limb and respiratory muscles and functions as a steroid hormone receptor in differentiated normal human skeletal muscle fibers...
