OBJECTIVE To compare the sensitivity and specificity of different phenotypic methods for detection of Amp C betalactamase producing bacteria. STUDY DESIGN Analytical study. PLACE AND DURATION OF STUDY Department of Microbiology, Army Medical College / National University of Sciences and Technology (NUST), Islamabad, Pakistan, from June 2010 to December 2010. METHODOLOGY A total of 150 cli...
Gene amplification (amp) is one of the basic mechanisms connected with overexpression of oncogenes. The c-MYC (located in 8q24) and MLL (located in 11q23) are the most often over represented genes that lead to a rapid proliferation of the affected cell clone in patients with myeloid neoplasms. Assessment of the level of amp c-MYC or amp MLL in the cases with trisomy 8 (+8) or trisomy 11 (+11) a...

Detection of Amp C genes encoding for beta-lactamases in Escherichia coli and Klebsiella pneumoniae.
PURPOSE Amp C beta-lactamase are Ambler class C enzymes that confer resistance to extended spectrum cephalosporins and are not inhibited by beta-lactamase inhibitors. Their detection is crucial, since the phenotypic tests are not standardised leading to ambiguity in interpretation of results. This study was done to detect the types of Amp C prevalent in Escherichia coli and Klebsiella pneumonia...
مقدمه: سرطان پستان یکی از شایعترین سرطانهای قابل پیشگیری در زنان است. روش خودآزمایی پستان یکی از روشهای پیشگیری از مرگ و میر، تشخیص زودرس و درمان آن میباشد. بدین منظور مطالعه حاضر جهت بررسی میزان آگاهی و نگرش دانشجویان دانشگاه الزهرا (س) درباره خودآزمایی پستان صورت گرفت. روشها: مطالعه مقطعی- تحلیلی حاضر با روش نمونهگیری تصادفی طبقهبندی شده، بر روی 135 دانشجوی دختر 18 تا 26 ساله دانش...
Norepinephrine and histamine markedly augment accumulations of cyclic AMP elicited by 2-chloroadenosine in a guinea pig cerebral cortical vesicular preparation. In addition, these biogenic amines stimulate phosphatidylinositol turnover. Phosphatidylinositol turnover is associated with mobilization of internal calcium and with stimulation of protein kinase C. Phorbol-12-myristate-13-acetate (PMA...
Hepatocytes were isolated from rats and then loaded with the fluorescent Ca2+ indicator quin2. Glucagon caused a sustained increase (at least 5 min) in the fluorescence of the quin2-loaded cells; the increase was much greater than that observed with control, non-quin2-loaded, cells. These observations indicate that glucagon caused an increase in cytoplasmic free Ca2+ concentration [( Ca2+]c). T...
Major changes in bacterial physiology including biofilm and spore formation involve signaling by the cyclic dinucleotides c-di-GMP and c-di-AMP. Recently, another second messenger dinucleotide, c-AMP-GMP, was found to control chemotaxis and colonization by Vibrio cholerae. We have identified a superregulon of genes controlled by c-AMP-GMP in numerous Deltaproteobacteria, including Geobacter spe...
جداسازی گازهای اسیدی از جریان گاز طبیعی با استفاده از محلول های آمینی یکی از متداول ترین روشها است. طراحی و بهینه سازی این گونه از واحدها نیاز به داده های دقیق تعادلی بخار-مایع دارد. از طرف دیگر بعلت غیر ایده آل بودن و وجود واکنش های شیمیایی و گونه های مختلف در فاز مایع، مدل سازی این سامانه ها برای توصیف رفتار آنها ضروری است. در این تحقیق ابتدا داده های تعادلی بخار-مایع حلالیت گاز h2s در غلظتها...
Cyclic AMP and cyclic GMP were released into the growth medium of mycelia of Neurospora crassa wild-type strains St.L.74A and Em5297a and by white collar-1 and white collar-2 mutant strains. After growth for 6 days at 18 degrees C, there were 2.19 (St.L.74A), 5.83 (Em5297a), 1.38 (white collar-1), and 1.10 (white collar-2) nanomoles of cyclic AMP per gram dry weight of mycelia in the growth med...
