conclusions this study demonstrated the co-existence of rmtc and blandm-1 genes for the first time in turkey. the spread of this resistant type should be monitored and limited through molecular surveillance. results twenty k. pneumoniae strains showed resistance to amikacin, and 40 were resistant to gentamicin. the mic value was found to be > 512 µg/ml in five amikacin-resistant strains and > 1...
We study the propagation of scalar fields in background an asymptotically de-Sitter black hole solution $f(R)$ gravity. The aim this work is to analyze modified theories gravity existence anomalous decay rate quasinormal modes (QNMs) a massive field which was recently reported Schwarzschild holes backgrounds, longest-lived are ones with higher angular number, for mass smaller than critical valu...
ظهور تکنولوژی های مهم ارتباطی بخصوص اینترنت، تحولاتی سریع و شگرفی در نوع روابط و تعاملات اجتماعی جامعه ایجاد کرده است. پیوندها و مشغولیت اجتماعی در جوامع گذشته که مبتنی بر روابط خانوادگی، روابط همسایگی و اجتماع محلی بود تغییر و تحول اساسی یافته است. اینترنت با ایجاد فضایی بدون محدودیت زمان و مکان، شرایط و زمینه را برای پیدایش نوع جدیدی از ارتباطات اجتماعی (راه دور ) فراهم ساخته است و مشغولیت اج...
background beta-lactam resistance in gram-negative bacteria, especially escherichia coli, is a main clinical problem. it is often caused by the co-production of β-lactamases, particularly extended-spectrum β-lactamases (esbls) and ampc enzymes. it may lead to a problem for diagnosis via recommended phenotypic tests by the clinical and laboratory standards institute (clsi). conversely, β-lactama...
Background and Objectives: Beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. Although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. Thus, the objectives are to study the validity of Naked-Eye-Single-Tube-Osmotic-Fragility-Test (NES...
Background: Beta thalassemia is one of the autosomal recessive diseases that related to synthesis disorder of beta globin chain. It is caused by any of the more than 200 mutations in the β-globin gene. DNA sequencing and genotyping of numerous mutations at beta globin gene is timely and expensive. Therefore, the best method for screening is linkage using polymorph markers at beta globin region ...
Background and Objective: β-Thalassemia major is a chronic genetic disease which is determined with symptoms and signs of a chronic severe anemia. Children with β-Thalassemia major have several risk factors for cognitive problems. The purpose of this study was to compare the cognitive function in β-thalassemia major children and healthy counterparts. Methods: This cross-sectio...
Background and purpose: The role of beta carotene in glucose metabolism in type ÏÏ diabetes is unclear. Thus this study was designed to investigate the effect of fortified carrot juice with beta carotene on glycemic indices in these patients. Materials and methods: This randomized controlled double blind clinical trial was performed on 44 patients with type ÏÏ diabetes. Ïnitially patients ...
Background and Purpose: TGF-β is a potent regulator and suppressor of the immune system and overproduction of this cytokine may contribute to immunosuppression in HIV-infected patients. Increasing population of immunosuppressed patients has resulted in increasingly frequent of fungal infections, including oral candidiasis. The aim of this study was to evaluate the plasma levels of TGF-&bet...
