The metabolism of sodium 3 alpha,7 beta-dihydroxy-5 beta-cholane-24-sulfonate and sodium 3 alpha,7 beta-dihydroxy-24-nor-5 beta-cholane-23-sulfonate was studied in hamsters. In bile fistula animals these sulfonate analogs of ursodeoxycholic acid were absorbed mainly from the terminal ileum and secreted rapidly into the bile without biotransformation or conjugation. After oral administration, th...
Biostimulation with different nitrogen sources is often regarded as a strategy of choice in combating oil spills in marine environments. Such environments are typically depleted in nitrogen, therefore limiting the balanced microbial utilization of carbon-rich petroleum constituents. It is fundamental, yet only scarcely accounted for, to analyze the catabolic consequences of application of biost...
Aldehyde dextran sulfonate (ADS), a modified oligosaccharide polymer, was used to prepare a new matrix structure for affinity biosensors. The principal difference between the ADS matrix and similar structures developed previously results from presence of two active functional groups in the matrix, namely, aldehyde and sulfonate. These groups perform two different functions in the matrix. The al...
Acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) is a severe, life-threatening medical condition characterized by widespread inflammation in the lungs, and is a significant source of morbidity and mortality in the patient population. New therapies for the treatment of ALI are desperately needed. In the present study, we examined the effect of andrographolide sulfonate, a wa...
Background. Herb-derived compound andrographolide sulfonate (called Xiyanping injection) recommended control measure for severe hand, foot, and mouth disease (HFMD) by the Ministry of Health (China) during the 2010 epidemic. However, there is a lack of good quality evidence directly comparing the efficacy of Andrographolide Sulfonate combination therapy with conventional therapy. Methods. 230 p...
in order to evaluate chemical mutation on cultivar mahali tarrom’ in salt stress, seeds of rice cultivar ‘mahali tarrom’ were treated with two chemical mutagens, ethyl methane sulfonate (14 mm) and sodium azide (two mm). in second generation, appropriate plants for economically important traits have been selected. seeding of selected plants were tested under salt stress in third generation usin...
Introduction : Previous researches showed that neutral soaps significantly increased bond strength and decreased microleakage of dentin bonding agents. The aim of this study was histopathological evaluation of the effect of sodium sulfonate application as neutral soap on the cat's dental pulp after an ideal composite restorative treatment . Methods: Ten adult cats with 40 caries-f...
In the title compound, {[Ag(C(9)H(6)N(3)O(3)S)]·H(2)O}(n), the Ag(I) atom is coordinated by three N atoms and two sulfonate O atoms from two different 4-(2-pyrid-yl)pyrimidine-2-sulfonate ligands. The ligand bridges two Ag(I) atoms, forming a polymeric zigzag chain propagating parallel to [001]. The uncoordinated water mol-ecule is involved in hydrogen bonds with sulfonate O atoms.
