Soil microbial communities are continuously exposed to H2 diffusing into the soil from the atmosphere. N2-fixing nodules represent a peculiar microniche in soil where H2 can reach concentrations up to 20,000 fold higher than in the global atmosphere (0.530 ppmv). In this study, we investigated the impact of H2 exposure on soil bacterial community structure using dynamic microcosm chambers simul...

Background: Acute poisoning is a common medical emergency. This study was designed to investigate the pattern of drug utilization, poisoning agents, and outcome in patients with acute poisoning treated at a tertiary care teaching hospital in Vadodara, west of India. Methods: This prospective cross sectional drug utilization study was carried out on patients with diagnosis of acute poisoning ad...

Molecular hydrogen (H2) is clinically administered; however, in some hospitals, H2 is given to patients without consideration of its safe use. In the present study, we prepared convenient and safe devices for the drinking of super-saturated H2 water, for intravenous drip infusion of H2-rich saline, and for the inhalation of H2 gas. In order to provide useful information for researchers using th...

introduction:  treatment of rapid ventricular response arterial fibrillation (rapid af) varies depending on the decision of the in-charge physician, condition of the patient, availability of the drug, and the treatment protocol of the hospital. the present study was designed aiming to compare iv digoxin and amiodarone in controlling the heart rate of patients presenting to emergency department ...

Background Molecular hydrogen (H2) is an attractive future energy carrier to replace fossil fuels. Biologically and sustainably produced H2 could contribute significantly to the future energy mix. However, biological H2 production methods are faced with multiple barriers including substrate cost, low production rates, and low yields. The C1 compound formate is a promising substrate for biologic...

Oxidative stress and neuroinflammation cause many neurological disorders. Recently, it has been reported that molecular hydrogen (H2) functions as an antioxidant and anti-inflammatory agent. The routes of H2 administration in animal model and human clinical studies are roughly classified into three types, inhalation of H2 gas, drinking H2-dissolved water, and injection of H2-dissolved saline. T...

Hyperpolarization-activated cyclic nucleotide–gated (HCN) channels, primarily their HCN4 subtype, are one of the promising targets for development cardioprotective agents. HCN channel blockers have a selective bradycardic effect, preserving myocardial contractility and diastolic function not affecting electrophysiological parameters heart. This review continues series reviews on analysis compou...

Heritability and interactions of yield and growth traits were assessed in Hevea brasiliensis using full-sib progenies and clonal populations. Using parent-offspring regression, annual mean rubber yield (ARY) and summer yield (SY) showed moderate to high heritability (ARY, h2 =34–56%; SY, h2 =36–52%). Among the yield components, girth exhibited low to moderate heritability (h2 =17–36%) while bra...

H2S retards H2 transport across Pd membranes used for H2 separation by forming a Pd4S scale that has both low H2 dissociation activity and low H-atom permeability. As hydrogen purification membranes, alloys such as Pd70Cu30 and Pd47Cu53 are attractive alternatives to pure Pd due to their resistance to formation of bulk sulfides. Nonetheless, exposure to H2S can decrease the permeability of Pd70...
