BACKGROUND Cystathionine γ-lyase (CSE) produces hydrogen sulfide (H2S) in the cardiovascular system. The deficiency of CSE in mice leads to a decreased endogenous H2S level, an age-dependent increase in blood pressure, and impaired endothelium-dependent vasorelaxation. To date, there is no direct evidence for a causative role of altered metabolism of endogenous H2S in atherosclerosis developmen...

PURPOSE To implement and validate methods for producing calculated coronal T2 maps with complete coverage of the hippocampus and the rest of the brain. METHODS T2 relaxation times were estimated on three occasions for 12 quality assessment test objects with the use of fast spin-echo (FSE) and conventional spin-echo (CSE) sequences. Hippocampal T2 relaxation times were measured in 15 healthy s...

AIMS In children with convulsive status epilepticus (CSE) with fever, to determine the likelihood of acute bacterial meningitis (ABM), the proportion that are treated with antibiotics, and the proportion that have diagnostic CSF sampling. METHODS Patients with an incident episode of CSE with fever were identified as part of an ongoing prospective population based study of CSE in childhood. ...

Nuclear erythroid related factor 2 (Nrf2) is a redox-sensitive transcription factor which is involved in the transcriptional regulation of many antioxidant genes, including glutamatecysteine ligase (GCL). Cigarette smoke is known to cause oxidative stress and deplete glutathione (GSH) levels in alveolar epithelial cells. We hypothesized that resveratrol, a polyphenolic phytoalexin, possesses an...

Hydrogen sulfide (H2S), generated in the osteoblasts predominantly via cystathionine-γ-lyase (CSE), is bone protective. Previous studies suggested that the onset of bone loss due to estrogen deficiency is associated to decreased levels of H2S and blunted gene expression of CSE. However, there are still a lot of unknowns on how H2S levels influence bone cells function. The present study aims to ...

Previous studies demonstrated that CSE induces oxidative stress and its consequences on isolated mitochondria obtained from lung, heart and brain which may provide insight into the role of CSE in human health and disease. The present study was carried out to further characterize and compare toxic effect of CSE extract on isolated mitochondria obtained from either a directly contacting tissue (i...

زمینه و هدف: افزایش عوامل التهابی متعاقب چاقی از دلایل اصلی مرگ‌ومیر است. اگرچه نقش تمرینات ورزشی، محدودیت کالریک مکمل‌های ضداکسایشی در این گزارش شده است، اثر همزمان هر سه مداخله مورد توجه پژوهشگران زیادی ازاین‌رو هدف پژوهش حاضر بررسی هشت هفته تمرین تناوبی شدید، کالری مکمل اسپرولینا بر بافت قلب موش‌های صحرایی تحت رژیم غذای پرچرب بود.مواد روش‌ها: 45 سر موش نر چاق‌شده با غذایی (60 درصد چربی، 20 پ...

This study aimed to investigate the link between exposure intimate partner violence (IPV), core self-evaluations (CSE), and psychological adaptation of Chinese adolescents, through analysis results from Survey Children’s Exposure Domestic Violence Scale, Core Self-Evaluations Strengths Difficulties Questionnaire, involving a total 597 middle school students. It is indicated that IPV positively ...

BACKGROUND Chronic inflammation, imbalance of proteolytic and antiproteolytic activities, oxidative stress, and apoptosis of lung structural cells contribute to the pathogenesis of COPD. There is increasing evidence that carboxymethylcysteine (also known as carbocisteine) (CMC), which is commonly used for its mucoactive property, has diverse pharmacologic actions, including significant antioxid...

BACKGROUND Hydrogen sulfide (H2S), produced by the activity of cystathionine-gamma-lyase (CSE), is a key mediator of inflammation in sepsis. The liver sinusoidal endothelial cells (LSECs) are important target and mediator of sepsis. The aim of this study was to investigate the role of CSE-derived H2S on inflammation and LSECs fenestrae in caecal-ligation and puncture (CLP)-induced sepsis using ...
