به منظور بررسی تأثیر شوری آب آبیاری بر برخی ویژگیهای شیمیایی و توزیع نمک در نیمرخ خاک تحت کشت سه رقم ذرت در شرایط استفاده از سیستم آبیاری قطرهای (نوارهای تیپ)، پژوهشی در سال 1396 در مزرعه پژوهشی گروه مهندسی آبیاری و آبادانی دانشگاه تهران، واقع در کرج به صورت آزمایش فاکتوریل و در قالب طرح بلوکهای کامل تصادفی انجام گرفت. تیمارهای آزمایشی شامل سه هیبرید ذرت، سینگلکراسهای 260، 400 و 70...
Background and objectives: Scrophularia atropatana (S. atropatana) is endemic to western and central regions of Iran. It belongs to the genus of Scrophularia (family: Scrophulariaceae). These species have been found to possess antibacterial, antitumor and anti-inflammatory properties. Most of these effects were proven to be attributed to the ...
Objective(s): The present study investigated the prevalence of genes encoding for exotoxins, adhesion and biofilm factors in Staphylococcus aureus isolates obtained from samples in a referral burn hospital in Tehran, Iran.Materials and Methods: S. aureus isolates obtained from patients, personnel and surfaces in the wards of a burn hospi...
Background and objectives: The seeds of Securigera securidaca (L.) Deg. & Dorf. (Fabaceae) are used as anti-diabetic remedy in Iranian folk medicine. The aim of the present study was to establish the callus and suspension culture of S. securidaca seeds for the first time and to determine the major secondary metabolites including cardiac glycosides and total ph...
چکیده مقدمه: سویههای جهش یافته مقاوم به آنالوگهای نوکلئوزیدی/نوکلئوتیدی ویروس هپاتیت B (HBV) در نتیجه طولانی شدن زمان مصرف و بروز پلیمرفیسم تک نوکلئوتیدی (SNP) و جهشهای گریز پدیدار میشوند. هدف از مطالعه حاضر، شناسایی فشارهای انتخابی و جهش فرار ایمنی در ژن HBsAg (S) در بیماران مبتلا به HBV مزمن است. روش کار: در این مطالعه مقطعی که در سال 1397 در...
Objective(s): Streptococcus pyogenes, a notorious human pathogen is responsible to cause a wide range of infections varies from superficial common clinical illness to severe and life threatening infections. To our knowledge this is the first report exploring the emm types and superantigen/exotoxin gene profile of S. pyogenes from Pakistan. Materials a...
Objective(s): Salsola collina is widely distributed along the Bohai coast and consumed as an edible plant by native residents. We have found surprisingly that S. collina extracts promoted gastrointestinal motility in mice previously. In the present study, effects of S. collina on gastrointestinal motility in rats and its underlying mechanism were explored.<st...
We prove that a type-definable Lascar strong type has finite diameter. We answer also some other questions from [1] on Lascar strong types. We give some applications on subgroups of type-definable groups. In this paper T is a complete theory in language L and we work within a monster model C of T . For a0, a1 ∈ C let a0Θa1 iff 〈a0, a1〉 extends to an indiscernible sequence 〈an, n < ω〉. We define...
Authenticated Key Exchange protocols enable several parties to establish a shared cryptographically strong key over an insecure network using various authentication means, such as strong cryptographic keys or short (i.e., low-entropy) common secrets. The latter example is definitely the most interesting in practice, since no additional device is required, but just a human-memorable password, fo...
