The effects of H2 gas treatment of an agricultural soil cultivated previously with a mixture of clover (Trifolium pratense) and alfalfa (Medicago sativa) on CO2 dynamics and microbial activity and composition were analyzed. The H2 emission rate of 250 nmol H2 g K1 soil h was similar to the upper limit of estimated H2 amounts emitted from N2 fixing nodules into the surrounding soil ([Dong, Z., L...

در طی چند سال اخیر صرفه جویی در مصرف انرژی و استفاده از منابع تجدیدپذیر بسیار مورد مطالعه قرار گرفته است. امروزه استفاده از فناوری تولید همزمان برق و حرارت یکی از روش های صرفه جویی در مصرف انرژی به شمار می رود. روش-های شیرین سازی آب بعنوان بخشی از فناوری تولید همزمان برق و حرارت می تواند هم موجب رفع کمبود آب و همچنین افزایش راندمان نیروگاه های حرارتی گردد. بدین منظور در چند سال اخیر از اینگونه ...

introduction: omperazole as a very useful drug in peptic ulcer which needs to be converted to active form and its activation requires acidic enviornments. h2 blockers and antacids can prevent this activation by elevation of ph in the gastrointestinal system thus diminishing omperazole effectiveness. in this study, cases of coadministration of omperazsole with h2 blockers and antiacids has been ...

Since the 2007 discovery that molecular hydrogen (H2) has selective antioxidant properties, multiple studies have shown that H2 has beneficial effects in diverse animal models and human disease. This review discusses H2 biological effects and potential mechanisms of action in various diseases, including metabolic syndrome, organ injury, and cancer; describes effective H2 delivery approaches; an...

A flber optic spectrophotometric system was used to monitor the in vivo oxygenation of leghemoglobin in intact, attached soybean root nodules (Glycine max L. Merr. x USDA 16 Bradyrhizobium japonicum) which were flattened during development by growth in narrow, glass-walled cuvettes. When equilibrated at an external P02 of 20 kilopascals, leghemoglobin was 36.6 ± 5.4% oxygenated, a value estimat...

Molecular hydrogen (H2) is effective for many diseases. However, molecular bases of H2 have not been fully elucidated. Cumulative evidence indicates that H2 acts as a gaseous signal modulator. We found that H2 suppresses activated Wnt/β-catenin signaling by promoting phosphorylation and degradation οf β-catenin. Either complete inhibition of GSK3 or mutations at CK1- and GSK3-phosphorylation si...

The recent discovery of ArH+ in the interstellar medium has awakened the interest in the chemistry of this ion. In this work, the ion-molecule kinetics of cold plasmas of Ar/H2 is investigated in glow discharges spanning the whole range of [H2]/([H2]+[Ar]) proportions for two pressures, 1.5 and 8 Pa. Ion concentrations are determined by mass spectrometry, and electron temperatures and densities...

Inhalation of molecular hydrogen (H2) gas ameliorates oxidative stress-induced acute injuries in the brain. Consumption of water nearly saturated with H2 also prevents chronic neurodegenerative diseases including Parkinson's disease in animal and clinical studies. However, the molecular mechanisms underlying the remarkable effect of a small amount of H2 remain unclear. Here, we investigated the...
