Background: Increasing global consumption of fossil fuels leads to greenhouse gas emissions, climate change and environmental pollution. Agricultural, animal and food industrial waste is one of the main sources of pollution. The bioethanol industry is one of 17 highly polluted industries. In the process of producing bioethanol, vinasse is produced, and so far 22.4 Giga litter of vinasse has bee...
The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding and DNA pairing. Therefore, the amplification of hydrogen bonds strength by substituents may be important in life scie...
objective(s):in recent years, the chemistry of tetrazolo[5',1':2,3][1,3,4]thiadiazepino [7,6-b]quinolines have received considerable attention owing to their synthetic and effective biological importance which exhibits a wide variety of biological activity. as the inhibitor of aldose reductase, the aforementioned compounds may have implication in preventing complications of diabetes. ...
New method for quantification of gasotransmitter hydrogen sulfide in biological matrices by LC-MS/MS
Hydrogen sulfide exists widely in mammalian tissues and plays a vital role in physiological and pathophysiological processes. However, striking differences with orders of magnitude were observed for the detected hydrogen sulfide concentrations in biological matrices among different measurements in literature, which lead to the uncertainty for examination the biological relevance of hydrogen sul...
Background and Aim: In this study, the removal of dye blue reactive-171 by combination of advanced oxidation processes UV/H2O2 and SBAR has been investigated. Methods: The efficiency of chemical and biological system was first investigated separately. In chemical system, the kind, power, initial dye concentration and hydrogen parasitize and in biological system, hydraulic detention time, aerati...

Backgrounds and Objectives: Nitrate is a water contaminant that can cause health problems in human and animals, in addition to eutrophication of the water body. So, Nitrate-contaminated water may be treated by treatment systems. In this study, hydrogenotrophic denitrification using hydrogen produced by Fe0 as an electron donor to nitrate removal was evaluated to assess the feasibility of employ...
