background: copper and zinc are the elements with numerous physiological activities. copper (cu) has an important role in angiogenesis and acts by increasing vascular endothelial growth factor (vegf). serum levels of copper will be increased in cancer incidence, progression and recurrence. the aim of this study was to measure blood levels of copper, zinc, and the ratio of cu /zn, as ...
Of all types of xenobiotics, pesticides such as herbicides play a significant role in soil and water pollution due to their widely usage all over the world. This study addresses the ability of organic amendments to enhance atrazine and metamitron degradation in two herbicide contaminated soils with contrasting textures under laboratory conditions. Soil samples were collected from surface soils ...
Fisher rats from a inbred colony, when fed on a salt-free high-protein diet, developed only a mild arthritis after adjuvant injection. Their spleen cells failed to respond in vitro to concanavalin A (a T-cell mitogen), although they possessed a B-cell function of plaque formation to sheep red blood cells. When a full salt supplement was included in the diet, or magnesium or copper or zinc was i...
مسمومیت با سرب در همه جانداران و از جمله در آبزیان از اهمیت ویژه ای برخوردار است. آلیسین یکی از مهمترین مواد موثره گیاه سیر می باشد که انتظار می رود با توجه وفور اسیدهای آمینه سولفور دار، اثر پیشگیری کننده در مسمومیت با سرب ایفا نماید. در این تحقیق به بررسی تأثیر آلیسین بر اثرات سمی سرب با توجه به فعالیت آنزیم های سرم خون در ماهی کپور پرداخته شده است. پنج گروه 25 تایی ماهی کپور (10 ±100گرمی) مو...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

The effects of inulin-supplemented diet on Cu, Mn, and Zn bioavailability in recently weaned piglets raised at an experimental and a commercial farm were studied. Piglets were weaned at 28 days of age, when all of them were fed a barley-wheat based starter diet supplemented with a usual vitamin-mineral premix for piglets. The reference diet group received additional 50 mg of zinc per kg diet, w...
Twenty-two surface soil samples (0-20 cm) from Fars province were extracted by five extractants (i.e., DTPA, 1.5 M NH4H2PO4, 0.1 NH3PO4, 0.05 MNa2EDTA, and 1% Na2EDTA) and used in a 7-week greenhouse experiment which was a 22 × 3 factorial with 22 soils (clay 16-63% pH 7.8-8.2 electrical conductivity 0.32-1.78 dS m-1 calcium carbonate equivalent 28-63% organic matter 1.1-4.9% cation exchange ca...
چکیده: بررسی مقایسه ای گونه های مختلف مالاسزیا در پوست و گوش گوساله های نوزاد با مادرانشان با استفاده از روشهای مورفولوژیکی، بیوشیمیایی و فیزیولوژیکی مخمرهای لیپوفیلیک جنس مالاسزیا جزء فلور نرمال جلدی انسان و حیوانات می باشند که تحت شرایطی بیماریزا می شوند. از آنجایی که نه تنها گونه غیر وابسته به چربی بلکه سایر گونه های مالاسزیا از حیوانات مختلف جداسازی می شود لذا بررسی اپیدمیولوژی و انتشار ج...
