background and objective: prostate cancer is a prevalent disease around the world. the prostatic specific antigen (psa) test has recently proved itself as a useful method for the diagnosis and examination of patients with prostatic cancer. the objective of this study was to compare the stability of free psa and total psa in different storage settings. materials and methods: samples were obtaine...

abstract the aphid parasitoids, aphidius colemnai viereck and a. matricariae (haliday) (hymenoptera: braconidae: aphidiinae) have high potential as the most effective biological control agents for controlling the cotton aphis aphis gossypii glover (hemiptera: aphididae). in this investigation, the effect of five constant temperatures (10, 15, 20, 25 and 30 °c) on the reproductive parameters was...

Probably the most common approach in the industry, particularly for frozen blocks, is to drill and probe. This doesn’t really measure “freeze time”, but it does tell the operator what the approximate core temperature is at the end of the freezing cycle. “Temperature Measurement and Fish”, the Torry Advisory Note of J.Graham (1977), gives a good account of these practices. The procedure for dril...

of reduced glutathione was detected and this decrease was fo11owed by a decrease in leyels of glucose 6-phesphate. When twigs that contained depressed leyels of reduced glutathione and glucose-6-phosphate were transferred to 40C, oyercompensation for the decrease in reduced glutathione and glucose-6-phosphate occurred and the resultant surplus appeared to reflect the metabolic dysfunction in th...

understanding the seed germination response of cultivated genotypes to temperature is important, agronomically. the genotypes that germinate in lower temperatures could be useful for situations (such as late winter plantings) where temperatures are low in germination stage. therefore, this experiment was conducted to study the cardinal temperatures, response to sub- or supra-optimal temperature...

Water hot-band lines were detected in comets C/1999 H1 (Lee), C/1999 S4 (LINEAR), and C/2001 A2 (LINEAR) in the 2.9 m spectral region using high-dispersion (k= k 2 ; 10) infrared spectroscopy with NIRSPEC at the W. M. Keck Observatory. The density of H2O emissions in this spectral region, the spectral coverage and resolution of NIRSPEC, and fluorescence models developed for these hot bands enab...

abstract consistent decreasing and increasing of temperature in the short-term period that is called freezing and thaw cycles is one of the important factors of damage to crop productions. in this research as to determine freezing and thaw cycles in the khorasan razavi province, the data of daily minimum and maximum temperatures of 9 synoptic stations was used over 20 statistic years (1989-2008...
