The event of partly grain-free ear is a crucial problem which can result in severe reductions in corn yield. In a two year field investigation, during 2003-2004, an experiment was conducted to determine the effect of  boron (B) and zinc (Zn) application on yield and yield components of corn (Zea mays L.) plants grown in a B and Zn-deficient calcareous soil (fine, carbonatic, thermic, Typic Hapl...

abstract zinc (zn) is an essential plant nutrient. knowledge about distribution of zn between its different chemical forms is useful in understanding the chemistry of this element in soil and also in development of soil testing procedures. the present study was conducted to obtain such information about distribution of zinc forms in 20 soil samples of lorestan province by the use of a sequentia...

The Cu,Zn superoxide dismutase (SOD) of Aspergillus fumigatus has previously been purified and shown to be immunoreactive to the sera of patients with aspergillosis; however, the purification of large quantities of the enzyme for expanded immunological analysis is both difficult and time-consuming. Accordingly, a lambdaEMBL3 A. fumigatus genomic library was screened with degenerate oligonucleot...

in order to study the effect of vermicompost individually and enriched with chemical fertilizer on soil micronutrient content and micronutrient concentration of lettuce (lactuca sativa l.), athree year experiment was conducted with randomized complete block design in two factors and three replications at the experimental farm of sari agricultural sciences and natural resources university in 200...

Background: The aim of present study was to estimate the levels of some minerals ( Zn, Se , Ca , Mg , Na and K ).Also relationships between mentioned components and some sperm parameters and the infertility period were studied as well. Materials and Methods: This study was performed on human semen specimens obtained from Asthenospermic patients (101 specimens) and Normospermic males (61 specime...

There is currently an increased consumption of vegetables within the local urban community. However, contamination of these vegetables with heavy metals poses a potential health hazard. Consequently, the potential contamination problem due to the effect of levels of some heavy metals (Fe, Mg, Zn, Mn, Cu and Cr) in soils and vegetables irrigated with drainage urban grey waste water were investig...

Endothelium-dependent flow-mediated dilation is a homeostatic response to short-term increases in local shear stress. Flow-mediated dilation of the brachial artery in response to postischemic reactive hyperemia is impaired in patients with cardiovascular disease risk factors and may reflect local endothelial dysfunction in the brachial artery. However, previous studies have largely neglected th...
