conclusions our successful extraction of purified lps from e. coli isolates of uti patients’ urine samples can be an important step to understand the uti disease conditions. results the silver-stained gel demonstrated both smooth and rough type lps by showing trail-like band patterns with the presence and lacking o-antigen region, respectively. coomassie blue staining showed no band assuring th...

a newly developed natural rubber deproteinization process produces deproteinized natural rubber (dpnr) wastewater as an intermediate product containing a high concentration of sodium dodecyl sulfate (sds) and rubber. in this study, a novel process to recover the residual rubber and energy as methane from dpnr wastewater was developed. as a pretreatment, sds and residual rubber in dpnr wastewate...

aquaculture is among the oldest occupations of human being. over the past quarter of century, the aquaculture industry has grown rapidly. the effect of water containing sodium sulfate on long term compressive strength of concrete of fishing ponds and channels is investigated in this paper. aim of this paper was to analyze the strength of concrete channels and of aquaculture which are in direct ...

OBJECTIVES To find a suitable method for detecting zinc sulfate in adulterated urine. METHODS Two rapid spot tests to detect the presence of zinc sulfate in urine were developed. RESULTS Addition of 3 to 4 drops of 1N sodium hydroxide solution to approximately 1 mL of urine containing zinc sulfate led to the formation of a white precipitate, which was soluble in excess sodium hydroxide. In ...

A study of the distribution of S35 in the rat, 14 to 16 hours after the intraperitoneal administration of sodium sulfate, labeled with S35, has been reported by Singher and Marinelli (1). Of particular interest is their observation that the highest concentration of the radioactive sulfur was found in the bone marrow. This observation stimulated us to determine the change with time in the concen...

BACKGROUND/AIMS Little is known about the anti-colitis effect of tryptophan or its metabolites. Here, the protective effect and its mechanism of tryptophan administration on dextran sulfate sodium -induced colitis in mice was studied. MATERIALS AND METHODS Twenty C57black6 female mice were equally divided into the control group, and treatment group. The control group received a standard CE-2 ...

The effect of hydrocarbon chain length on chemical selectivity in micellar electrokinetic chromatography (MEKC) was investigated using polymeric sulfated surfactants: poly-(sodium 7-octenyl sulfate), poly(sodium 8-nonenyl sulfate), poly(sodium 9-decenyl sulfate), and poly(sodium 10-undecenyl sulfate). Linear solvation energy relationships (LSERs) and free energy of transfer studies were conduct...

Release of different heavy metals from various industries is a significant environmental hazard worldwide. In order to reduce the threat these chemicals, treatment methods are needed make them harmless. This study approaches problem by examining effect gypsum content for immobilization selenium oxyanions selenite and selenate, sulfate, with calcium sulfoaluminate belite (CSAB) cement-based ettr...

in an environmentally benign solventless system, aldehydes and ketones were readily converted to their corresponding azines with hydrazine sulfate, sodium hydroxide and alumina in high yield.
