The Rhodococcus FMF (R. FMF) native bacterium was isolated from soil contaminated with oil in Tabrizrefinery. This bacterium carries three genes sox (dszA, B, C) on its genomic DNA. Preliminary studieshave proved that R. FMF strain possess desulfurization activity. In this work soxA and B genes wereamplified by PCR, after designing a pair of suitable primers. Analysis of PCR p...

Objective(s): The enzymatic activity of fungi has recently inspired the scientists with re-explore the fungi as potential biofactories rather than the causing agents of humans and plants infections. In very recent years, fungi are considered as worthy, applicable and available candidates for synthesis of smaller gold, silver and other nano-sized particles.  Materials and Methods: A standard str...

conclusions: left ventricular systolic heart failure, may result in inter and intra-atrial asynchrony even in clinically stable patients without significant pulmonary hypertension and diastolic dysfunction. results: in heart failure patients either inter or intra-atrial asynchrony were far more common in comparison with normal subjects (p=0.008 and p=0.007 respectively). patients and methods: t...

background two-dimensional (2d) strain is a new reproducible technique for assessing regional myocardial function; however, its application for evaluation of left atrium (la) function is less studied. objectives we sought to assess la function in heart failure patients using velocity vector imaging (vvi). patients and methods thirty five patients (mean age: 43.34 ± 18.1 years, 59.3% male) with ...

The comprehension of the anisotropy impacts on mechanical properties of the rolled steel sheets was investigated using a non-quadratic anisotropic yield function. In this study, experimental and modelling determination regarding the behaviour of an industrial rolled sheet for a ferritic stainless low-carbon steel were carried out. The parameters of the associated yield equation, derived from th...

background :  young chickens are more susceptible to salmonella colonization than older ones that have developed resistance with age as native microflora become established.   methods :  in this study, two groups of fertile eggs were inoculated with 20 cfu of hila or parent strains of s . enteritidis . presence and number of salmonella cells inside the homogenized egg contents were determined on...

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

Goniothalamin was evaluated for its anti-malaria activity in-vivo, using the 4-Day Suppressive Test (Peters & Robinson, 1975). The test were carried out against two strains of rodent malaria parasites, the sensitive strain P. berghei ANKA (MRA 311) strain and the resistant strain P. yoelii (MRA 312). An Initial screening was carried out using a single dose of 10 mg/kg body weight administered s...

Introduction: Nowadays, excessive computer use in the workplace has raised concerns about the health status of VDT workers, particularly complaints about eye discomforts. Due to the importance of the eyelids and eye closure parameters on eye health during computer works and the direct effect of monitor height on these parameters, this study was aimed to examine the effect of different monitor h...
