The biogenesis of iron-sulphur clusters requires the co-ordinated delivery of both iron and sulphur. It is now clear that sulphur in iron-sulphur clusters is derived from L-cysteine by cysteine desulphurases. However, the iron donor for the iron-sulphur cluster assembly still remains elusive. Our previous studies indicated that Escherichia coli IscA, a member of the iron-sulphur cluster assembl...

A field experiment was conducted during 2018–19 and 2019–20 at the research farm of ICAR-Directorate Rapeseed-Mustard Research, Bharatpur, Rajasthan to evaluate effect organic inorganic nitrogen sources on yield, water productivity, system productivity economics maize (Zea mays L.)-mustard [Brassica juncea (L.) Czern.] cropping system. The in split-plot design with recommended levels fertilizer...

BACKGROUND Iraq used chemical weapons against thousands of Iranian militaries and civilians. This study aimed to compare the chronic cutaneous side effects of exposure to sulfur mustard (SM) with nerve agents (NA). METHODS The study enrolled 154 SM exposed cases and 175 (NA) exposed cases. Presence of any late cutaneous manifestations was evaluated by a dermatologist via prior history of acut...

Sulphur-doped carbon was synthesized using a thiophene-based twin monomer. While tetra(thiophene-2-ylmethoxy)-silane can be converted into sulphur containing nanocomposites, which lead to microporous sulphur-doped carbon, it is possible to produce additional mesopores by the use of templates. Thus, a variety of sulphur-doped carbon materials with tailored pore texture are available.

Though sulphur has long been recognized as an essential element in plants, particularly as a constituent of the proteins, it has not received much consideration in fertilizer studies. As shown by the work of HART and PETERSON (3), this was partly due to the older practice of determining sulphur in the ash of vegetation, which gave low results and did not indicate the true sulphur needs of the p...

Selenocyanate (SeCN(-)) is a major contaminant in the effluents from some oil refineries, power plants, and in mine drainage water. In this study, we determined the potential of Indian mustard (Brassica juncea) and muskgrass (a macroalga, Chara canescens) for SeCN(-) phytoremediation in upland and wetland situations, respectively. The tolerance of Indian mustard to toxic levels of SeCN(-) was s...

To the Editor: Approximately 5% of young children and 4% of adults have some type of adverse immune responses to foods in westernized countries. Mustard is a widely consumed spice that can trigger life-threatening IgE-mediated allergic reactions. Mustard is frequently consumed as a hidden allergen in foods, resulting in unexpected allergic reactions. It has been reported that more than 50% of p...

the interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. at different time intervals, plasma and urine samples were collected. the binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-ideal ...

in this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. the trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. the industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. the study was composed of two parts. in the first section...

this paper is a state-of-the-art in sulphur-asphalt (sa) design technology based on a comprehensive analysis of current practice and technical literature, in order to investigate the possible use of sa pavements in iran. in this paper, the major aspects(material, technology, properties, production, placement, quality assurance, design, and field varification) of sa pavements are considered. fer...
