BACKGROUND AND OBJECTIVES Acetic acid bacteria (AAB) are useful in industrial production of vinegar. The present study aims at isolation and identification of acetic acid bacteria with characterization, optimization, and evaluation of their acetic acid productivity. MATERIALS AND METHODS Samples from various fruits were screened for presence of acetic acid bacteria on glucose, yeast extract, ...

BACKGROUND Diabetes mellitus (DM) is an endocrine disease characterized by hyperglycemia, the pathogenic mechanisms by which hyperglycemia arises differ widely. Monitoring people with diabetes involve repeated estimations of plasma glucose either by finger pricks or by intravenous blood sampling. Hence, a noninvasive procedure for glucose measurements would be most precious under the circumstan...

Changes in the visible absorption spectra of dyes due to binding with polyelectrolytes of high molecular weight are known as metachromasy and have been extensively studied. Recent advances in metachromasy have been summarized in several reviews (1-3). It is also known that metachromasy due to binding with proteins is generally weak but oc curs with both acidic and basic dyes. Methyl orange (MO)...

BACKGROUND The effect of the redox state of human serum albumin (HSA) on the antioxidant properties of the entire body has been a focus of recent research. The usefulness of HSA redox state as a biomarker for reducing oxidative stress has been investigated in clinical settings; however, evidence for its significance as a health index in non-clinical settings is yet to be established. This study...

INTRODUCTION/OBJECTIVE We evaluated the predictability of early changes in serum albumin (sAlb) on the two-year mortality of incident hemodialysis patients. METHODS Observational, longitudinal retrospective study using the database of Fresenius Medical Care of Latin America. Adult patients starting dialysis from January/2000 to June/2004, from 25 centers were included. Changes in sAlb during ...

green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. the “green” architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices. so, green architecture is building and structure design philosophy that aims at minimal use of non-renewable and/or...

The removal of model pollutants bromocresol green (BG) and phenol from water is demonstrated via two liquid-liquid extraction methods. Both methods exploit selective interactions established by the pollutant molecule with a surfactant, oil, or alcohol, and are variants of the more general Winsor systems where the phases are in contact along an extremely large interfacial area. In the first meth...

Birds are uricotelic, and because they excrete urate by renal tubular secretion, they provide a convenient model for examination of this process. Primary monolayer cultures of the isolated renal proximal tubule epithelium from the domestic chicken, Gallus gallus L., were mounted in Ussing chambers where several substrates/inhibitors of renal organic anion transporters were tested for the sidedn...

Background: Glycation is the process of non enzymatic addition or insertion of sugar to proteins, DNA and lipids. Fructosamine is the generic name for plasma proteins ketoamines; it refers to structure of ketoamine rearrangement product formed by interaction of fructose with ε-amino group of lysine residues of albumin. Its determination monitors the short term glycemic changes and may have a ro...
