| 2017 | 1 Of the study population, 57.6% were females with mean age of 30.3 years (range, 4–66) and the rest were males with mean age of 38.6 years (range, 1–79). Most infections were due to Escherichia coli (10.7%), followed by other members of family Enterobacteriaceae, Staphylococcus aureus and Pseudomonas aeruginosa. Table 1 outlines the performance of the urinalysis tests for detection of...

The combination of lanthanide ions and nitronyl nitroxide radicals resulted in four new Ln-radical one-dimensional compounds, namely, [Ln(hfac)3{NIT-Ph(OMe)2}]n(Ln(III) = Sm (1), Eu (2), Gd (3), Dy (4); hfac = hexafluoroacetylacetonate; NIT-Ph(OMe)2 = 2-(2',4'-dimethoxyphenyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-1-oxyl-3-oxide). The four complexes were found to be isomorphous and exhi...

The WAM traditionally optimizes for lists in two ways: by a list-specialized instruction set (LSIS) and by a list-specialized data representation (LSDR). These are partly orthogonal and their relative merit is unknown. In this paper, we perform an experiment within hProlog, which compares the schemas (LSIS+LSDR), (LSIS) and (). If no LSDR is used, it means that lists are treated as the syntacti...

isoniazid, is the only antituberculous drug for which the relation between lack of virulence and acquisition of resistance was associated. inh-resistant mutants were shown to contain defective katg gene. classical studies showed that inh-resistant south indian isolates have lower virulence in guinea pigs and higher susceptibility to h2o2. it is of interest to assess the virulence in south india...

  Photoproteins are excellent reporter systems because they don’t have virtually background signal. Aequorin is the most well-known photoprotein. Three improved engineered photoproteins photina, i-photina and c-photina, were also recently developed and optimized for generation of Ca2+ mobilization assays precisely. The total light emission is greater than aequorin and their reacti...

Quinolones are a large and widely consumed class of synthetic drugs. Expanded-spectrum quinolones, like ciprofloxacin are highly effective against Gram-negative bacteria, especially Escherichia coli. In E. coli the major target for quinolones is DNA gyrase. This enzyme is composed of two subunits, GyrA and GyrB encoding by gyrA and gyrB, respectively. Mutations in either of these genes cause qu...

The temperature induced neutral to ionic phase transition (TI-NIT) is a rare phenomenon occurring in mixed stack charge transfer (CT) crystals made up of alternating $\ensuremath{\pi}$-electron donor (D) and acceptor (A) molecules. We were able grow tetrathiafulvalene-fluoranil (TTF-FA), show that it undergoes TI-NIT like the prototype CT crystal TTF-chloranil. characterized both room low-T pha...

به منظور تعیین تنوع ژنتیکی pyricularia grisea، 35 جدایه تک اسپور بر اساس انگشت نگاری dna به روش rep-pcr و شناسایی گروه های سازگاری رویشی در این تحقیق استفاده شدند. جدایه ها در سالهای 1376-1378 از خوشه های آلوده به بیماری بلاست مزارع برنج استان گیلان جمع آوری گردید. برای تعیین تنوع ژنتیکی و شناسایی دودمان های کلونی پراکنده در جمعیت قارچ، از دو آغازگر طراحی شده بر اساس توالی نوکلئوتیدهای قطعه eri...

plants showing root and crown rot were collected from 48 bean fields in the khuzestan and markazi provinces during 2005-2006. using specific primers (fsphr/fsphf) for these forma specialis, three isolates were identified as f.s. f.sp. phaseoli. conidial suspension of one of these isolates were irradiated (in a 60co- gamma cell with activity of 2500 curi and 0.38 grey per second dose rates) with...
