One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

maize improvement for high temperature tolerance requires the reliable assessment of parental inbred lines and their combinations. fifteen maize inbred lines were evaluated during 2007 and 2008 in shushtar city (khuzestan province). the inbred lines were planted at two dates: 6 july, to coincide heat stress with pollination time; and 27 july, as normal planting to avoid high temperature during ...

background: the normal prostate-specific antigen (psa) level in patients with urethral catheterization is a controversy. we designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum psa. materials and methods: seventy patients scheduled for urethral catheterization before elective surgeries were randomly selected and included in th...

Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...

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 Method...

In this study, two new Ni/La-Al2O3 catalysts were prepared by a sol-gel method, with different aluminium precursors (aluminium triisopropoxide and aluminium nitrate). The catalysts were characterized by scanning electron microscope (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), BET specific surface area, and particle size analysis (PSA) techniques. The BET results showed that the par...

in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...
