We reported previously that although there is disruption of coordinated cardiac hypertrophy and angiogenesis in transition to heart failure, matrix metalloproteinase (MMP)-9 induced antiangiogenic factors play a vital role in this process. Previous studies have shown the cardioprotective role of hydrogen sulfide (H₂S) in various cardiac diseases, but its role during transition from compensatory...
BACKGROUND Nanomaterials are widely used in industry for their specific properties. Silver nanoparticles (Ag NPs) are largely used in several consumer products notably for their antibacterial properties and will likely be found in wastewater, then in the receiving environment. The development of a product capable to sequestrate those released contaminants is needed. Under environmental conditio...
As a novel gasotransmitter, hydrogen sulfide (H(2)S) has vasodilating and antihypertensive effects in cardiovascular system. Thus, we hypothesized that H(2)S might have beneficial effects on thoracic endothelial function in two-kidney one-clip (2K1C) rats, a model of renovascular hypertension. Sodium hydrosulfide (NaHS, 56 micromol/kg/day) was administrated intra-peritoneally from the third day...
The purpose of the present study was to define the indirect central effect of hydrogen sulfide (H(2)S) on baroreflex control of sympathetic outflow. Perfusing the isolated carotid sinus with sodium hydrosulfide (NaHS), a H(2)S donor, the effect of H(2)S was measured by recording changes of renal sympathetic nerve activity (RSNA) in anesthetized male rats. Perfusion of isolated carotid sinus wit...
BACKGROUND A reduction in cochlear blood flow plays an essential role in noise-induced hearing loss (NIHL). The timely regulation of cochlear perfusion determines the progression and prognosis of NIHL. Hydrogen sulfide (H(2)S) has attracted increasing interest as a vasodilator in cardiovascular systems. This study identified the role of H(2)S in cochlear blood flow regulation and noise protecti...
Hydrogen sulfide (H2S) has anti-fibrotic potential in lung, kidney and other organs. The exogenous H2S is released from sodium hydrosulfide (NaHS) and can influence the renal fibrosis by blocking the differentiation of quiescent renal fibroblasts to myofibroblasts. But whether H2S affects renal epithelial-to-mesenchymal transition (EMT) and the underlying mechanisms remain unknown. Our study is...
Endoplasmic reticulum (ER) stress has been implicated in several neurodegenerative diseases, including Parkinson's disease. The present study attempted to investigate the effect of hydrogen sulfide (H(2)S) on 6-hydroxydopamine (6-OHDA)-induced ER stress in SH-SY5Y cells. We found in the present study that exogenous application of sodium hydrosulfide (NaHS; an H(2)S donor, 100 μM) significantly ...
Corticosterone, one of the glucocorticoids, is toxic to neurons and plays an important role in depressive-like behavior and depression. We previously showed that hydrogen sulfide (H2S), a novel physiological mediator, plays an inhibitory role in depression. However, the mechanism underlying H2S-triggered antidepressant-like role is not clearly known. Brain-derived neurotrophic factor (BDNF), a ...
The current study aimed to examine the renoprotective effects of long-term treatment with sodium hydrosulfide (NaHS), a prominent hydrogen sulfide donor, in 5/6 nephrectomy animal model. Twenty-four rats were randomly divided into 3 groups including sham-operated group (Sham), 5/6-nephrectomized group (5/6 Nx), and NaHS-treated group (5/6Nx+NaHS). NaHS (30 micromol/l) was added twice daily into...
Hydrogen sulfide (H2S) plays a crucial signalling role in variety of physiological systems, existing as the hydrosulfide anion (HS−) at pH. Combining potency halogen bonding (XB) for recognition water with coumarin fluorophore incorporation acyclic host structural design, first XB receptors to bind and, more importantly, sense pure reversible chemosensing fashion are demonstrated. The exhibit c...
