Hydrogen sulfide potentiates the favorable metabolic effects of inorganic nitrite in type 2 diabetic rats.

Decreased nitric oxide (NO) bioavailability and hydrogen sulfide (HS) deficiency have been linked with the pathophysiology of type 2 diabetes (T2D). Restoration of NO levels by nitrite have been associated with favorable metabolic effects in T2D. Moreover, HS can potentiate the effects of NO in the cardiovascular system. The aim of this study was to determine the effects of long-term co-administration of sodium nitrite and sodium hydrosulfide (NaSH) on carbohydrate metabolism in type 2 diabetic rats.

Nitric oxide and hydrogen sulfide crosstalk during heavy metal stress in plants.

Gases such as ethylene, hydrogen peroxide (H O ), nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H S) have been recognized as vital signaling molecules in plants and animals. Of these gasotransmitters, NO and H S have recently gained momentum mainly because of their involvement in numerous cellular processes. It is therefore important to study their various attributes including their biosynthetic and signaling pathways. The present review provides an insight into various routes for the biosy...

Comparing the preventive effect of sodium hydrosulfide, leptin, and curcumin against L-arginine induced acute pancreatitis in rats: role of corticosterone and inducible nitric oxide synthase.

Acute pancreatitis (AP) is a life-threatening condition. Using antioxidants in AP is insufficient and conflicting. Therefore, this study compared the effect of hydrogen sulfide (H2S) donor, sodium hydrosulfide (NaHS), leptin or curcumin pretreatment on AP induced by L-arginine.

Exogenous nitric oxide alleviates sulfur deficiency-induced oxidative damage in tomato seedlings.

Despite numerous reports on the role of nitric oxide (NO) in regulating plants growth and mitigating different environmental stresses, its participation in sulfur (S) -metabolism remains largely unknown. Therefore, we studied the role of NO in S acquisition and S-assimilation in tomato seedlings under low S-stress conditions by supplying NO to the leaves of S-sufficient and S-deficient seedlings. S-starved plants exhibited a substantial decreased in plant growth attributes, photosynthetic pigment chlorophyl...

After cold stress treatment, we examined morphological damage, oxidative stress indexes, inflammatory factors, and intestinal microbiota. Results of morphological examination...

Regulation of boar sperm functionality by the nitric oxide synthase/nitric oxide system.

Nitric oxide (NO) is a free radical synthesized mainly by nitric oxide synthases (NOSs). NO regulates many aspects in sperm physiology in different species. However, in vitro studies investigating NOS distribution, and how NO influences sperm capacitation and fertilization (IVF) in porcine, have been lacking. Therefore, our study aimed to clarify these aspects.

Mandibular lateral deviation induces alteration in vascular endothelial growth factor expression and oxidative stress/nitric oxide generation in rat condyle, synovial membrane and masseter muscle.

We aimed to investigate alteration in cellular signaling mediated by vascular endothelial growth factor (VEGF) and parameters of oxidative stress/nitric oxide generation, superoxide dismutase (SOD) and neuronal nitric oxide synthase (nNOS), underlying altered functional mechanical loading of TMJ (temporomandibular joint) during lateral mandibular deviation.

Production and localization of hydrogen peroxide and nitric oxide in grapevine cells elicited with cyclodextrins and methyl jasmonate.

The use of methyl jasmonate, alone or in combination with cyclic oligosaccharides such as cyclodextrins, has proved to be a successful strategy for increasing the production of trans-resveratrol in Vitis vinifera cell cultures. However, understanding the intracellular signalling pathways involved in its production would improve the management of grapevine cells as biofactories of this high-value natural product. The results obtained herein confirm the involvement of hydrogen peroxide and nitric oxide in cyc...

The total antioxidant capacity (T-AOC), malonaldehyde (MDA) and nitric oxide (NO) content, superoxide dismutase (SOD) and catalase activity (CAT), the immune-relative gene (caspase-3, hsp70 and IMD) expression in hepatopancreas and intestine of L.vannamei and...

Regulation of physiological aspects in plants by hydrogen sulfide and nitric oxide under challenging environment.

Plants are exposed to a plethora of abiotic stresses like drought, salinity, heavy metal and temperature stresses at different stages of their life cycle, from germination to seedling till reproductive phase. As protective mechanisms, plants release signalling molecules that initiate a cascade of stress-signalling events, leading either to programmed cell death or plant acclimation. Hydrogen sulphide (H S) and nitric oxide (NO) are considered as new 'gasotransmitter' molecules which play key roles in regula...

Novel α-ketoamide based diazeniumdiolates as hydrogen peroxide responsive nitric oxide donors with anti-lung cancer activity.

A novel type of hydrogen peroxide (H2O2)-activated diazeniumdiolate based on an α-ketoamide moietey was developed as a nitric oxide (NO) donor. KA-NO-4 inhibited lung cancer cells with submicromolar activity. The H2O2-responsive behaviour of KA-NO-4 was thoroughly investigated. The NO-centered mechanism of action of KA-NO-4 was intracellularly studied.

Nitric Oxide in Pulmonary Hypoplasia: Results from the European iNO Registry.

The aim of this work was to describe treatment response and outcome data for preterm infants with pulmonary hypoplasia treated with inhaled nitric oxide (iNO). We hypothesised that an acute oxygenation response to iNO would be associated with survival.

Sulfate assimilation regulates hydrogen sulfide production independent of lifespan and reactive oxygen species under methionine restriction condition in yeast.

Endogenously produced hydrogen sulfide was proposed to be an underlying mechanism of lifespan extension via methionine restriction. However, hydrogen sulfide regulation and its beneficial effects via methionine restriction remain elusive. Here, we identified the genes required to increase hydrogen sulfide production under methionine restriction condition using genome-wide high-throughput screening in yeast strains with single-gene deletions. Sulfate assimilation-related genes, such as , , , and , were found...

Hydrogen sulfide-induced oxidative stress leads to excessive mitochondrial fission to activate apoptosis in broiler myocardia.

Hydrogen sulfide (HS), as an environmental gas pollutant, has harmful effects on many tissues and organs, including myocardium. However, the underlying mechanisms of H2S-induced myocardia toxicity remain poorly understood. The present study was designed to investigate the effect of HS on myocardia injury in broilers from the perspective of apoptosis. 30 ppm H2S was administered in the broiler chamber for 2, 4 and 6 week, respectively, and the myocardial samples in control groups and H2S groups were collec...

Acyl Selenyl Sulfides as the Precursors for Reactive Sulfur Species (Hydrogen Sulfide, Polysulfide, and Selenyl Sulfide).

Persulfides are receiving increased attention due to their links to hydrogen sulfide (HS) and hydrogen polysulfide (HS ). Their close analogues selenyl sulfides (RSeSHs), however, have limited literature precedent, and their reactivity and possible role in biology are largely unknown. Here, we devised an acyl selenyl sulfide template to study RSeSH chemistry. Their stability and reactivity toward amines/thiols were studied. These compounds can produce HS or HS under different conditions, suggesting that RSe...

Hydrogen gas alleviates toxic effects of cadmium in Brassica campestris seedlings through up-regulation of the antioxidant capacities: Possible involvement of nitric oxide.

Hydrogen gas (H) has been shown as an important factor in plant tolerance to abiotic stresses, but the underlying mechanisms remain unclear. In the present study, the effects of H and its interaction with nitric oxide (NO) on alleviating cadmium (Cd) stress in Brassica campestris seedlings were investigated. NO donor (SNP) or hydrogen-rich water (HRW) treatment showed a significant improvement in growth of Cd-stressed seedlings. Cd treatment upregulated both endogenous NO and H (36% and 66%, respectively), ...

Propofol But Not Desflurane Maintains Rat Cerebral Arteriolar Responses to Acetylcholine During Acute Hyperglycemia.

Acute hyperglycemia causes vascular endothelial dysfunction in various organs including the cerebral vessels. It is associated with increased mortality and morbidity in the perioperative period. The impact of anesthetic agents on cerebral vasodilatory responses during hyperglycemia remains unclear. We investigated endothelial function in rat cerebral arterioles during acute hyperglycemia, under propofol or desflurane anesthesia.

Characterization of Dialkyldithiophosphates as Slow Hydrogen Sulfide Releasing Chemicals and Their Effect on the Growth of Maize.

Hydrogen sulfide is a key gasotransmitter for plants and has been shown to greatly increase their growth and survival to environmental stressors. Current methods to use chemicals, such as GYY-4137, that slowly release hydrogen sulfide result in the release of chemicals not found in the environment and may lack chemical structures that can be readily tuned to affect their release of hydrogen sulfide. In this article we describe the synthesis and slow release of hydrogen sulfide from dialkyldithiophosphates w...

The effects of fine particulate matter constituents on exhaled nitric oxide and DNA methylation in the arginase-nitric oxide synthase pathway.

Fine particulate matter (PM) has been widely associated with airway inflammation represented by increased fractional concentration of exhaled nitric oxide (FeNO). However, it remains unclear whether various PM constituents have different impacts on FeNO and its production process from the arginase (ARG)-nitric oxide synthase (NOS) pathway.

Methods for the Addition of Redox Compounds.

Often in redox biology experiments there is a need to add compounds which impinge on the redox of the cellular environment cell. Such compounds may include reactive oxygen species (ROS), such as hydrogen peroxide (HO), reactive nitrogen species such as nitric oxide (NO), hydrogen sulfide (HS), or even hydrogen gas (H). It is not always easy or obvious how such compounds should be used. Gases may be supplied and used in the gaseous form, but this is often not convenient. Alternative methods may involve donor...

Oxidative stress assessment in breath-hold diving.

Breath-hold diving results in significant changes in blood gases' levels. Challenging variations in oxygen partial pressures may induce reactive oxygen species (ROS) production that exacerbate oxidative stress and, consequently, affect endothelial function. The aim of this study was to investigate the effects of breath-hold diving on oxidative stress damage, assessing ROS production. Nitric oxide metabolites, inducible nitric oxide synthase (iNOS), aminothiols, and renal function were evaluated too as marke...
