This study determined the reliability of dipstick urinalysis for detection of protein, glucose, blood and nitrites in non-random urine samples from 300 people aged > 50 years attending a health centre for check-up. The gold standards were fasting blood glucose for glucosuria and the sulfosalicylic acid method for urine protein. Microscopic examination of urinary sediment and urine culture were ...

The asymmetric unit of the title helical coordination polymer, {[Ni(C(7)H(4)O(6)S)(C(10)H(8)N(2)S)(2)(H(2)O)(2)]·2H(2)O}(n), is comprised of an Ni(II) ion, one 5-sulfosalicylic acid dianion (HSSA), two 4,4'-dipyridylsulfide (4,4'-dps) ligands, and two coordinated and two uncoordinated water mol-ecules. The Ni(II) ion is coordinated by two water mol-ecules, one carboxyl-ate O atom of the HSSA di...

Many methods have been devised to detect the action of bacterial cultures in or on gelatin media. The traditional gelatin stab technique involves incubation of the culture below the thermal liquefaction point of the gelatin in order to inaintain the gel structure so that the shape and size of the liquefied portion can be observed. A long incubation time is usually required. Bertiau (1914) sugge...

Human platelets and platelet particulate fractions were found to emit a burst of chemiluminescence during incubation with arachidonic acid. The magnitude of light emission was directly related to the number of platelets in the reaction mixture and varied little for the same individual from day to day. The chemiluminescence response of platelets was localized to the particulate fraction and was ...

The structures of the 1:1 anhydrous salts of nicotine (NIC) with 3,5-di-nitro-salicylic acid (DNSA) and 5-sulfosalicylic acid (5-SSA), namely (1R,2S)-1-methyl-2-(pyridin-3-yl)-1H-pyrrolidin-1-ium 2-carb-oxy-4,6-di-nitro-phenolate, C10H15N2 (+)·C7H3N2O7 (-), (I), and (1R,2S)-1-methyl-2-(pyridin-3-yl)-1H-pyrrolidin-1-ium 3-carb-oxy-4-hy-droxy-benzene-sulfonate, C10H15N2 (+)·C7H5O6S(-), (II), are ...
