Until pure erythropoietin was available, estimation of its molecular size depended on measurement of biological activity, with the inherent inaccuracy characteristic of bioassay methods. Previous measurements of molecular weight, by means of radiation inactivation (1)) gel permeation chromatography (2, 3), and a combination of density gradient centrifugation and gel permeation (4) have ranged f...

Urinalysis is often interfered by vitamin C and PH. This study was to evaluate the interference of PH in urinalysis, minimize risk make effective communication. 732 leftover urine samples which concentration 0.0 mmol/L either test-strip results (Glucose, Blood, Bilirubin, Leucocyte, Nitrite, Protein, Ketone) positive that were collected. The test checked out using these samples. When chemical p...

We assessed the reproducibility, recovery, and stability of several circulating metabolites--glucose, pyruvate, lactate, alanine, glutamate, glutamine, 3-hydroxybutyrate, acetoacetate, and glycerol--in the presence of sulfosalicylic acid (SSA), which was used to deproteinize blood. The assays, which involved reactions linked to NADH/NAD+, were carried out at 37 degrees C and measured at 355 nm ...

Epoxy coatings incorporating different content of sulfosalicylic acid doped polyaniline (PANI-SSA) have been investigated for corrosion protection of 5083 aluminum alloy in 3.5% NaCl solution. The performance of the coatings is studied using a combination of electrochemical impedance spectroscopy (EIS), open circuit potential (OCP), gravimetric tests, adhesion tests, scanning electron microscop...

Co-crystallization of 4,4'-methyl-enediphenyl-amine (MDA) and 5-sulfosalicylic acid (5-H(2)SSA) yields the title salt, C(13)H(16)N(2) (2+)·2C(7)H(5)O(6)S(-)·H(2)O. The asymmetric unit is comprised of one dication, two anions and one water mol-ecule. In the crystal structure, the components of the salt are linked by a combination of inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds into...

Titanium dioxide nanoparticles surface-modified by 5-sulfosalicylic acid 5-SA-TiO2 were prepared in ethanol by the chemisorption process. The effects of surface improvement on the photocatalytic degradation and adsorption of methyl orange MO were studied in a batch system by considering the various parameters, such as contact time, adsorbent dosage, pH, initial dye concentration and temperature...

Many studies show the antioxidant ability of parasite plant. This study aims to determine capacity Dendrophthoe pentandra (L.) Miq and Scurrula ferruginea stem from Syzygium aqueum use as a natural source. The sample was taken host aqueum. sampels were exraction with ethanol using maceration. parameters determined spectrophotometrically specific reagents that 1,1-diphenyl-2-picrylhydrazyl, phen...
