Certain diagnostic kits that measure serum urate by the Barham and Trinder principle of enzymic liberation of oxygen and its combination with chromogens can give results for urate in fresh serum that are approximately 20% lower than results from serum stored at ambient temperature for 72 h. In fresh serum, antioxidants compete with chromogen for liberated peroxyl-oxygen. We postulate that durin...

After intravenous injection of S-adenosyl-L-homocysteine3H (homocysteine-labeled) into rats, less than 15% of the radioisotope was incorporated into protein methionine or excreted in the urine as oc-ketobutyrate. The remaining radioisotope was found associated with an unknown keto acid excreted in the urine. Intravenous injection of Sadenosyl-L-homocysteine-35S or S-adenosyl-3H-L-homocysteine (...

In this work, a sustainable and green process to prepare nanocrystalline cellulose (NCC) from bleached hardwood pulp was demonstrated. Rod-like nanocrystalline cellulose with the size of 15-40 nm in width and hundreds of nanometers in length was obtained through H3PW12O40 (HPW)-catalyzed hydrolysis of bleached pulp fibers under the mild reaction conditions. Thermogravimetric analysis revealed t...

Objetive: To evaluate the correlation between salivary biomarkers (the antioxidant ability, level of polyphenols, and other antioxidants) with plaque-induced gingivitis exacerbated by pregnancy in pregnant nonpregnant women. Material Methods: For this observational study, medical records, dental examinations, analyses saliva samples were carried out A p-value <0.05 was considered significant...

Energy is a need of society and industry which increasing every year. However, the world's oil reserves continue to run low, so development renewable alternative energy needed. One new energies that can be developed vegetable fuel or biofuel. Biodiesel type biofuel being widely produced recently. The cetane number determines quality biodiesel. Solketal an additive added biodiesel increase numbe...

The process of infection of lupin nodule cells by rhizobia was examined using thin-section and freeze-fracture electron-microscopic techniques to characterize the properties of different membranes and to establish relationships between them. The membranes of the Golgi bodies and the endoplasmic reticulum stained with zinc iodide-osmium tetroxide but not with phosphotungstic acid or silver. By c...

A 26-mo-old female Crl:CD-l@(ICR)BR mouse in good general health was euthanized at the end of a study. At necropsy, a single cyst 5 mm in diameter was found in the left ovary, and multiple 2-4-mm cysts were seen in the endometrium. ...

Reportedly, levodopa (L-DOPA) administration produces spuriously high values for plasma uric acid as measured by the commonly used phosphotungstic acid-hydroxylamine colorimetric method. We confirm this interference, not only by L-DOPA but also by three of its major metabolites: dopamine, 3,4-dihydroxyphenylacetic acid, and 3-methoxy-4-hydroxyphenylacetic acid. However, at therapeutic concentra...
