Phytoestrogens has recently been claimed to positively influence menopausal discomforts, including hot flashes. However, little is known about the influence of phytoestrogens on core body temperature during estrogen fluctuation at menopause. With many published findings that phytoestrogens could relieve menopausal complaints, the present review was aimed at assessing the effects of phytoestrogens on thermoregulatory mechanism during menopausal transition. Thephytoestrogens of interest in relation to human health include isoflavones, lignans, coumestans and stilbenes, which are widely distributed within nature...

Persistence or recurrence of angina after successful percutaneous coronary intervention (PCI) represent an important clinical issue involving from one fifth to one third of patients undergoing myocardial revascularization at one-year follow-up. A systematic approach to this syndrome is strongly needed. Precision medicine is particularly important in addressing angina after successful PCI because of the multiple underlying causes. Restenosis or coronary atherosclerosis progression explain symptom recurrence after successful PCI in some patients, while functional causes, including vasomotor abnormalities of epicardial coronary arteries and/or coronary microvascular dysfunction, explain symptoms in the remaining patients...

BACKGROUND: Human saphenous veins used for arterial bypass undergo stretch injury at the time of harvest and preimplant preparation. Vascular injury promotes intimal hyperplasia, the leading cause of graft failure, but the molecular events leading to this response are largely unknown. This study investigated adenosine triphosphate (ATP) as a potential molecular mediator in the vascular response to stretch injury, and the downstream effects of the purinergic receptor, P2X7R, and p38 MAPK activation...

BACKGROUND: Intraoperative hypothermia and postoperative pain control are two important clinical challenges in anesthesiology. Transient receptor potential vanilloid 1 has been implicated both in thermoregulation and pain. Transient receptor potential vanilloid 1 antagonists were not advanced as analgesics in humans in part due to a side effect of hyperthermia. This study tested the hypothesis that a single, preincision injection of a transient receptor potential vanilloid 1 antagonist could prevent anesthesia-induced hypothermia and decrease the opioid requirement for postsurgical hypersensitivity...

Natural aging brings reduced production of growth and sex hormones, beginning in middle age, with noticeable physiologic changes by the sixth or seventh decade of life: reduced muscle mass, energy, and exercise capacity and alterations in sexual function. Hormones and hormone precursors have been investigated to delay changes in body composition, strength, and physical and cognitive function. Menopausal hormone therapy is effective for vasomotor and genitourinary symptoms. Testosterone is effective in men with hypogonadism and declines in physiologic function...

BACKGROUND: Aortocaval compression by the gravid uterus, low baseline vasomotor tone, and spinal anesthesia-related sympathetic blockade contribute to spinal anesthesia-induced hypotension during cesarean delivery. The finger perfusion index (PI) can predict spinal hypotension by reflecting baseline vasomotor tone, but cannot directly reflect aortocaval compression by the gravid uterus. This study aimed to examine whether baseline toe PIs predict the incidence of maternal hypotension and reflect aortocaval compression by the gravid uterus during cesarean delivery under spinal anesthesia...

Positron emission tomography/computed tomography (PET/CT) applied with positron-emitting flow tracers such as (13)N-ammonia and (82)Rubidium enables the quantification of both myocardial perfusion and myocardial blood flow (MBF) in milliliters per gram per minute for coronary artery disease (CAD) detection and characterization. The detection of a regional myocardial perfusion defect during vasomotor stress commonly identifies the culprit lesion or most severe epicardial narrowing, whereas adding regional hyperemic MBFs, myocardial flow reserve (MFR), and/or longitudinal flow decrease may also signify less severe but flow-limiting stenosis in multivessel CAD...

Apixaban (APX) is a direct inhibitor of factor X (FXa) approved for prophylaxis and treatment of deep venous thrombosis and atrial fibrillation. Because FXa activates protease-activated receptor 2 (PAR-2) in endothelium and vascular smooth muscle, inhibition of FXa by APX may affect vasomotor function. The effect of APX was assessed in vitro, by wire myography, in rat mesenteric resistance arteries (MRAs) and basilar arteries challenged with vasoconstrictors [phenylephrine (PE); 5-hydroxytryptamine (5-HT)], vasodilators [acetylcholine (ACh); sodium nitroprusside (SNP)] or with the PAR-2 peptide agonist SLIGRL...

The epidemiological link between hypertension and Alzheimer disease is established. We previously reported that hypertension aggravates the Alzheimer-like pathology in APPPS1 mice (amyloid precursor protein/presenilin-1, mouse model of Alzheimer disease) with angiotensin II-induced hypertension, in relation with hypertension and nitric oxide deficiency. To provide further insights into the role of nitric oxide in the hypertension-Alzheimer disease cross-talk, we studied the effects of nitric oxide blockade in APPPS1 mice using N(ω)-nitro-l-arginine methyl ester (l-NAME) alone or in combination with hydralazine, to normalize blood pressure...

Cardiac surgery with cardiopulmonary bypass and cardioplegic arrest is associated with injury to the vasculature and microcirculation leading to coronary microvascular dysfunction, permeability changes and cardiac dysfunction. In the setting of cardiopulmonary bypass with cardioplegia, poorly-controlled diabetes is associated with significant changes in endothelium-dependent and independent vascular dysfunction, vascular reactivity, vascular permeability, protein expression, cell death, coronary/peripheral microcirculation and reduced vasomotor tone leading to hypotension and impaired endothelial function...

Nuclear medicine imaging is widely used in pain medicine. Low back pain is commonly encountered by physicians, with its prevalence from 49% to 70%. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually used to evaluate the cause of low back pain, however, these findings from these scans could also be observed in asymptomatic patients. Bone scintigraphy has an additional value in patients with low back pain. Complex regional pain syndrome (CRPS) is defined as a painful disorder of the extremities, which is characterized by sensory, autonomic, vasomotor, and trophic disturbances...

Under physiologic conditions, losartan showed a dose-dependent antagonistic effect to the endothelin-1 (ET-1)-mediated vasoconstriction. This reduced vasoconstriction was abolished after preincubation with an endothelin B1 receptor (ET(B1)-receptor) antagonist. Also, an increased ET(B1)-receptor-dependent relaxation to sarafotoxin S6c (S6c; an ET(B1)-receptor agonist) was detected by preincubation with losartan. Investigations after experimental induced subarachnoid hemorrhage (SAH) are still missing. Therefore, we analyzed losartan in a further pathological setup...

Prostate cancer is the most common cancer among men and androgen deprivation therapy (ADT) is the most effective treatment for this disease. The cornerstone of the treatment of prostate cancer is inhibition of testosterone production which interrupts testosterone-induced growth of the prostate tumor. The dramatic decrease in testosterone levels, however, has several undesirable effects on the metabolic profile and bone metabolism and can also lead to fatigue, loss of libido, gynecomastia, and anemia, provoke vasomotor flushing, and generally affect the quality of life...

Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...
