The relative molecular size distributions of a selection of starches (waxy maize, pea and maize) that had received differing amounts of damage from ball milling (as quantified by susceptibility to alpha-amylase) were compared using analytical ultracentrifugation. Starch samples were solubilised in 90% dimethyl sulfoxide, and relative size distributions were determined in terms of the apparent d...

BACKGROUND Recent reports on the state of the global environment provide evidence that humankind is inflicting great damage to the very ecosystems that support human livelihoods. The reports further predict that ecosystems will take centuries to recover from damages if they recover at all. Accordingly, there is despair that we are passing on a legacy of irreparable damage to future generations ...

Selection of shaft geometry is critical to the overall performance of a rotary compressor. Consideration is given to the development of rotary compressor shaft geometries to optimize efficiency and reliability. The cylinder to piston dynamic clearance is of prime importance with respect to leakage losses. An analysis of bearing film thicknesses and shaft deflection was conducted to fully evalua...

to evaluate the flour quality 10 flour plants were selected in iran, tehran province. two kinds of flour were sampled from each plant (flour with 87% extraction named straight-run- flour as well as patent flour). samples were analyzed for their moisture content, ash, maximum viscosity of dough, particle size, falling number and the amount of damaged starch, which was determined through maltose ...

Concerns about damage to agricultural products due global warming are increasing year by year. In apple cultivation, high temperatures cause defects in color and other characteristics, warm weather winter causes a decrease cold resistance, which is associated with low frost. addition, storms floods occurs frequently. Nagano Prefecture, various fruit varieties cultivated using relay system. Ther...

Clinically healthy adult black Bengal female goats were used to investigate the pharmacokinetics of closantel following intravenous administration (10 mg/kg) both in healthy and in liver damaged goats. Induction of liver damage was done by subcutaneous injection of carbontetrachloride at 0.75 mL/kg on three occasion at 48 h interval. After administration of drug, blood samples were collected in...

Repairing damaged DNA is essential for an organism's survival. UV damage endonuclease (UVDE) is a DNA-repair enzyme that can recognize and incise different types of damaged DNA. We present the structure of Sulfolobus acidocaldarius UVDE on its own and in a pre-catalytic complex with UV-damaged DNA containing a 6-4 photoproduct showing a novel 'dual dinucleotide flip' mechanism for recognition o...

The stability of the commonly used red cell radio labels chromium-51, indium-(111 or 113m), and technetium-99m, within intact red cells and stroma and their distribution within the cell were compared in undamaged and heat damaged red cells in relation to the clinical use of heat damaged cells in the assessment of splenic function. Chromium-51 labelled haemoglobin both in undamaged and heat dama...

BACKGROUND Interstital cystitis is often treated with exogenous glycosaminoglycans such as heparin, chondroitin sulphate (Uracyst), hyaluronate (Cystistat) or the semi-synthetic pentosan polysulphate (Elmiron). The mechanism of action is presumed to be due to a coating of the bladder surface to replace the normally present chondroitin sulphate and heparan sulphate lost as a result of the diseas...
