Previous studies have shown that muscle sympathetic nerve activity (MSNA) is reduced during low- and mild-intensity dynamic leg exercise. It has been suggested that such inhibition is mediated by loading of the cardiopulmonary baroreceptors and that this effect is overridden by muscle metaboreflex activation with higher intensity exercise. However, limited data are available regarding the interaction between the cardiopulmonary baroreflex and the muscle metaboreflex. Therefore, we tested the hypothesis that cardiopulmonary baroreflex-mediated inhibition of MSNA is attenuated during high intensity muscle metaboreflex activation...

Purpose: An association between endocrine treatment-related symptoms and breast cancer recurrence has been suggested previously; however, conflicting results have been reported. We performed a meta-analysis of published studies to clarify this relationship. Methods: We systematically searched PubMed, Embase, Scopus, and the Cochrane database for studies investigating the association between endocrine treatment-related symptoms and patient survival. Random-effects meta-analysis was conducted with recurrence rate as the primary outcome...

Introduction: Insulin signaling in adipose tissue has been shown to regulate insulin's effects in muscle. In muscle, perivascular adipose tissue (PVAT) and vascular insulin signaling regulate muscle perfusion. Insulin receptor substrate (IRS) 2 has been shown to control adipose tissue function and glucose metabolism, and here we tested the hypothesis that IRS2 mediates insulin's actions on the vessel wall as well as the vasoactive properties of PVAT. Methods: We studied PVAT and muscle resistance arteries (RA) from littermate IRS2+/+ and IRS2-/- mice and vasoreactivity by pressure myography, vascular insulin signaling, adipokine expression, and release and PVAT morphology...

Aim: Menopause is a physiological process, with potential to lead to various pathological/psychological complications, leading to change in quality of life (QOL). Although literature suggests the effect of menopause on various aspects of life, there is scarcity of studies from rural setup in this regard. Thus, it is essential to assess extent of menopause-related changes, its awareness, and coping mechanisms in rural couple. This study aimed to find the prevalence of postmenopausal symptoms, its severity, and effect on QOL of rural women and the couples' coping mechanisms...

Activation of the apelin/APJ receptor signaling system causes endothelium-dependent and nitric oxide (NO)-dependent relaxation in several peripheral arteries. The effects of apelin in cerebral arteries are unknown; however, apelin inhibits voltage-dependent increases in large-conductance, calcium-activated K channel (BKCa) currents in cerebral artery smooth muscle cells. Because NO-induced relaxation of cerebral arteries is mediated, in part, by activation of BKCa channels, the goals of this study were to determine the net effect of apelin in cerebral arteries, as well as test the hypothesis that the actions of apelin in cerebral arteries are secondary to stimulation of APJ receptors...

Untreated vasomotor symptoms of the menopause can have a major impact on women at work. Recent recommendations advocate modification of the working environment, including adequate air-conditioning, to help relieve these symptoms. However, this may cause discomfort for work colleagues. We report the case of a 40-year-old woman with cold urticaria. Cold urticaria is a serious, potentially life-threatening condition. Our patient's symptoms were exacerbated when her postmenopausal work colleagues turned the air-conditioner temperature down to relieve their vasomotor symptoms...

Studies of the effects of physical activity on cognition suggest that aerobic fitness can improve cognitive abilities. However, the physiological mechanisms for the cognitive benefit of aerobic fitness are less well understood. We examined the association between aerobic fitness and cerebrovascular function with neurocognitive functions in healthy, young adults. Participants aged 18-29 years underwent measurements of cerebral vasomotor reactivity (CVMR) in response to rebreathing-induced hypercapnia, maximal oxygen uptake (VO2 max) during cycle ergometry to voluntary exhaustion, and simple- and complex-neurocognitive assessments at rest...

Chronic kidney disease affects more than 10% of the population. Programming studies have examined the interrelationship between environmental factors in early life and differences in morbidity and mortality between individuals. A number of important principles has been identified, namely permanent structural modifications of organs and cells, long-lasting adjustments of endocrine regulatory circuits, as well as altered gene transcription. Risk factors include intrauterine deficiencies by disturbed placental function or maternal malnutrition, prematurity, intrauterine and postnatal stress, intrauterine and postnatal overnutrition, as well as dietary dysbalances in postnatal life...

In the contemporary era of medical diagnosis via sophisticated radiographic imaging and/or comprehensive serological testing, a focused physical examination remains paramount in recognizing the cutaneous manifestations of chronic vascular disease. Recognition of the unique cutaneous signs of lymphatic and venous hypertension assists in the diagnosis as well as the staging and classification of both lymphedema and chronic venous insufficiency. Awareness of explicit dermatologic vasomotor manifestations aids not only in the identification of acrocyanosis, Raynaud phenomenon, pernio, and erythromelalgia but also mitigates confusion related to their clinical overlap...

OBJECTIVE: Seventy percent of postmenopausal women experience vasomotor symptoms, which can be highly disruptive and persist for years. Hormone therapy and other treatments have variable efficacy and/or side effects. Neurokinin B signaling increases in response to estrogen deficiency and has been implicated in hot flash (HF) etiology. We recently reported that a neurokinin 3 receptor (NK3R) antagonist reduces HF in postmenopausal women after 4 weeks of treatment. In this article we report novel data from that study, which shows the detailed time course of this effect...

The coupling of energy homeostasis to thermoregulation is essential to maintain homeothermy in changing external environments. We studied the role of the cold thermoreceptor TRPM8 in this interplay in mice of both sexes. We demonstrate that TRPM8 is required for a precise thermoregulation in response to cold, in fed and fasting. Trpm8-/- mice exhibited a fall of 0.7 °C in core body temperature (Tc) when housed at cold temperatures, and a deep hypothermia (below 30 °C) during food deprivation. In both situations TRPM8-deficiency induced an increase in tail heat loss...
