However, in the female group, the plasma arginase level increased with age (p = 0.05). Its biological significance was unclear. As a whole, the ELISA method for the measurement of arginase concentration in the body fluid is convenient and reliable.Soo-Ray...
The OA produced is subject to a second reaction mixture containing NADH and malate dehydrogenase (MDH) which reduces the OA to malate and oxidizes the NADH to NAD+. The CO2 level in the sample may be indirectly determined by measuring the change in NADH concentration. An inhibitor is added ...
The concentration of an enzyme in a biological fluid is determined by measuring either its mass by immunological techniques, or its enzyme activity. 7. Measurement of serum markers in the diagnosis and prognosis of disorders, tissue dysfunction, and/or damage is a vital component of clinical manag...
The concentrations of AI and AII were high in the epididymal plasma and epididymal cell when compared with the respective concentrations in blood serum. The intraluminal AII concentration found (13 nmol/l) was close to the threshold concentrations that stimulate anion (and fluid) secretion in ...

present. The fact that the activation energy is lower is the greatest effect of the catalyst as it allows the reaction to occur, at the rates required, in the relatively cool conditions within the cells. The enzymes can do this in one, or more, of three ways. These are as follows:
Considering that the AA concentration in the human body is more than 10 times lower than that of glucose35, the selectivity of the device is good enough for practical applications. Discussion The detectable range of the SGGT glucose sensor is from 0.5 mM to 1 mM, which is a suitable range...
In a biphasic system the benzaldehyde is predominantly in the organic phase and the de facto substrate concentration in the buffer phase was calculated by determination of the partition coefficient MTBE-H2O of benzaldehyde. Each reaction was performed in duplicate as two different independent experiments...
synthesizing F-cells (Fig. 8D). The latter may be secreted into the hepatopancreatic tubules together with the enzymes. Acidic mucopolysaccharides may help to inhibit the enzymes when present in high concentration in the gastric fluid, but may lose this property when their concentration is lowered...
The cells were maintained at 37°C in a humid atmosphere with 5% CO2. For orthotopic inoculation, the cells were trypsinised and suspended in Matrigel (BD Biosciences, San Jose, CA, USA) at a concentration of 106 cells/mL and stored on ice. The viability of the cells was confirmed by ...
