تالاب انزلی یکی از بوم سازگان مهم آبی در ایران است که در جنوب دریای خزر قرار دارد و زیستگاه ماهیان، آبزیان و پرندگان با ارزشی است که از ابعاد اکولوژیک و اقتصادی درخور توجهند. یکی از آلاینده های موجود در این تالاب ترکیبات آلی پایدار هستند، این سموم با گسترش وسیع در محیط زیست به عنوان یکی از مشکلات آلودگی جهانی شناخته می شوند که به علت حلالیت بالا در چربی و پایداریشان در محیط زیست می توانند در بد...
PURPOSE Mountain trekking involves level, uphill, and downhill walking (DW). Prolonged DW induces damage to leg muscles, reducing force generating ability and muscle coordination. These increase risks for more serious injuries and accidents in mountain trekking, thus a strategy to minimize muscle damage is warranted. It has been shown that low-intensity eccentric contractions confer protective ...
Plasma concentrations of thyroxine (T4), triiodothyronine (T3) and chicken GH (cGH), together with hepatic 5'-monodeiodination (5'-D) activity, were measured in normal (Dw) and dwarf chick (dw) embryos at incubation d 18. An injection of 10 micrograms of ovine GH (oGH) raised plasma concentrations of T3 in Dw embryos after 1 and 2 h and stimulated hepatic 5'-D activity after 2 h. A non-specific...
A simple multi-residue method was developed for detecting and quantifying 33 analytes from 13 classes of antibiotics (tetracyclines (3), quinolones (7), penicillins (3), ionophore coccidiostats (7), macrolides (3), sulfonamides (1), quinoxalines (2), phenicols (2), lincosamides (1), diaminopyrimidines (1), polypeptides (1), streptogramins (1) and pleuromutilins (1)) in animal feeds. Extraction ...
به منظور شناسائی ژنوتیپ های پرمحصول و پایدار گندم دوروم برای مناطق گرم و خشک کشور آزمایشی با 18 ژنوتیپ برتر انتخابی به همراه دو شاهد (گندم دوروم رقم بهرنگ و گندم نان رقم چمران) در چهار منطقه خرم آباد، داراب، دزفول و اهواز در قالب طرح بلوک های کامل تصادفی با سه تکرار به مدت دو سـال زراعی (90-89 و91–90)کشت و مورد ارزیابی قــرار گرفتند. برای عملکرد دانه داده های حاصل از هر یک از آزمایش ها به طور ج...
The essential oils and aromatic water, known as Arak in traditional Iranian medicine, comes from the aerial part of Teucrium persicum Boiss., which is grown in Fars Province located in Iran. The samples were collected in summer and the oils and aromatic water were obtained through steam distillation. The chemical composition of the oils was analyzed using GC-MS. An analysis of the chemical...
Controlling domain wall (DW) generation and dynamics behaviour in ferromagnetic nanowire is critical to the engineering of domain wall-based non-volatile logic and magnetic memory devices. Previous research showed that DW generation suffered from a random or stochastic nature and that makes the realization of DW based device a challenging task. Conventionally, stabilizing a Néel DW requires a l...
The hypothalamic tuberoinfundibular dopaminergic (TIDA) neurones secrete dopamine, which inhibits prolactin secretion. TIDA neurone numbers are deficient in Ames (df/df) and Snell (dw/dw) dwarf mice, which lack prolactin, growth hormone and thyroid-stimulating hormone. Prolactin therapy initiated before 21 days maintains normal-sized TIDA neurone numbers in df/df mice and, when initiated as ear...
Diffusion imaging of post-mortem brains could provide valuable data for validation of diffusion tractography of white matter pathways. Long scans (e.g., overnight) may also enable high-resolution diffusion images for visualization of fine structures. However, alterations to post-mortem tissue (T2 and diffusion coefficient) present significant challenges to diffusion imaging with conventional di...
