abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Zearalenol was extracted from Fusarium-infected stems of corn from southern Italy. The toxin, which appeared as a single compound in various thin-layer chromatography systems, was resolved by high-pressure liquid chromatography into two components. A gas chromatography-mass spectrometry examination of a purified fraction confirmed the natural occurrence of zearalenol as a diastereomeric mixture...
Abstract Background & Aims: Staphylococcus aureus is one of the most common causes of food poisoning. Methicillin resistant S. aureus usually are resistant to other antibiotics currently used for treatment. The aim of this study was determination of the prevalence of entrotoxigenic S.aureus in creamy pastries sold in Urmia and determining the rate of resistance to methicillin among the obta...
The aim of this research was to study the antifungal properties of propionibacteria. Three fractions from cultures of Propionibacterium freudenreichii ssp. shermanii 41 and ssp. freudenreichii 111 (i.e. culture containing viable bacteria, cell-free supernatant and bacteriocin preparation) were tested for their ability to inhibit the growth and mycotoxin production of Alternaria alternata, Fusar...
طی سال های 89-1388 از مزارع گندم 8 استان کشور شامل تهران، اصفهان، اردبیل، گلستان، مازندران، مرکزی، قزوین و زنجان در مرحله پر شدن دانه بازدید و از بوته های آلوده به پوسیدگی طوقه و ریشه نمونه برداری شد. شناسایی گونه های فوزاریوم با بهره گیری از هر دو روش مورفولوژیکی و مولکولی با استفاده از نشانگر اختصاصی (scar) گونه ها صورت گرفت و مجموعا 12 گونه فوزاریوم شناسایی گردیدکه عبارت بودند از:f. culmorum...
Fungi belonging to Fusarium genus can infect crops in the field and cause subsequent mycotoxin contamination, which leads to yield and quality losses of agricultural commodities. The mycotoxin zearalenone (ZEN) produced by several Fusarium species (such as F. graminearum and F. culmorum) is a commonly-detected contaminant in foodstuffs, posing a tremendous risk to food safety. Thus, different s...
the present dissertation aims to investigate four-word lexical bundles in applied linguistics research articles by iranian and internationally-published writers. the aims of this study are two-fold: first of all, attempts have been made to create a comprehensive list of the most commonly used four-word lexical bundles categorized by their type and token frequency, their structural characteristi...
Background & Aims : Aminoglycosides are powerful bactericidal agents used in combination with betalactams or gelicopeptitds, particularly in the treatment of staphylococcal infections. The main objective of this study was to investigate phenotypic and genotypic properties of aminoglycoside resistance in methicillin resistant S. aureus. Materials & Methods : During 8 months, out of 98 Stap...
