High circulating concentrations of homocysteine (ie, hyperhomocysteinemia [Hhcy]) impair the vascular function of peripheral conduit arteries and arterioles perfusing splanchnic and skeletal muscle regions. The effects of HHcy on coronary resistance vessel function and other indexes of vascular
Methionine is an essential proteinogenic amino acid found in many foods. During its metabolism homocysteine is formed. With elevated level of homocysteine in the blood--hyperhomocysteinemia--increased risk of developing certain diseases, such as non-alcoholic fatty liver disease, is associated.
Cardiovascular diseases connected with atherosclerosis are the main factor of morbidity and mortality in patients with end-stage renal failure. Hyperhomocysteinemia is a known and independent risk factor of atherosclerosis, occurring in 85-95% patients treated with hemodialysis. The aim of this
Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia behind Alzheimer's disease (AD) and is a frequent co-morbidity with AD. Despite its prevalence, little is known about the molecular mechanisms underlying the cognitive dysfunction resulting from cerebrovascular
Hyperhomocysteinemia (HHcy) is associated with endothelial dysfunction (ED), but the mechanism is largely unknown. In this study, we investigated the role and mechanism of HHcy-induced ED in microvasculature in our newly established mouse model of severe HHcy (plasma total homocysteine, 169.5 μM).
Insufficient hydrogen sulfide (H2S) has been implicated in Type 2 diabetic mellitus (T2DM) and hyperhomocysteinemia (HHcy)-related cardiovascular complications. We investigated the role of H2S in T2DM and HHcy-induced endothelial dysfunction in small mesenteric artery (SMA) of db/db mice fed a high
High plasma levels of homocysteine, termed hyperhomocysteinemia, are a risk factor for vascular cognitive impairment and dementia, which is the second leading cause of dementia. While hyperhomocysteinemia induces microhemorrhages and cognitive decline in mice, the specific effect of
The purpose of the present study was to investigate the effects of chronic methionine treatment on vascular smooth muscle contractility for angiotensin II (Ang II). Methionine at 0.1, 1 and 2 g/kg body weight was administered daily in the drinking water for 2, 4, 8 and 16 weeks. Rat carotid rings
Homocysteinemia is a major and independent risk factor for vascular disease. Oxidative stress is a possible mechanism for homocysteine (HCY)-induced vascular disease. Herein, we evaluated the antioxidant property of melatonin (MLT) in relation to the vasoconstrictive effect of HCY on the human
TREATMENT OF ARTERIAL HYPERTENSION - Blood pressure (BP) should be regularly measured in all patients with CKD (Strength of Recommendation C). - BP control and proteinuria reduction delay progression of CKD (Strength of Recommendation A) and reduce cardiovascular risk (Strength of Recommendation C).
BACKGROUND
Stroke is a leading cause of death. Current therapeutic strategies have been unsuccessful. Several studies have reported benefits on reducing stroke risk and improving the poststroke associated functional declines in patients who ate foods rich in fruits and vegetables. Their potential
Normal vascular endothelium is essential for the synthesis and release of substances affecting vascular tone (e.g. nitric oxide; NO), cell adhesion (e.g. endothelins, interleukins), and the homeostasis of clotting and fibrinolysis (e.g. plasminogen inhibitors, von Willebrand factor). The
The present study investigated the possible role of Janus kinase-2 (JAK-2) in hyperhomocysteinemia-induced attenuation of the cardioprotective effects of ischemic preconditioning (IPC). Rats were administered L-methionine (1.7 g/kg/day, p.o.) for 4 weeks to produce hyperhomocysteinemia. Isolated
Arterial hypertension is a major public health problem in sub-Saharan Africa due to its high frequency and to the cardiovascular risk that it entails. The purpose of this study was to assess the prevalence of clinical and biological risk factors of hypertension in Bamako In this study, we investigated the effects of L-homocysteine (Hcy) on maxi calcium-activated potassium (BK) channels and on exocytosis of secretory granules in GH3 rat pituitary-derived cells. A major finding of our study indicates that short-term application of Hcy increased the open probability of
