We report the complete genome sequence, including five complete plasmid sequences, of Escherichia coli ST131 isolate JJ1886. The isolate was obtained in 2007 in the United States from a patient with fatal urosepsis and belongs to the virulent, CTX-M-15-producing H30-Rx sublineage.
Cellular immunophenotypic studies were performed on a cohort of randomly selected IgM1 B-chronic lymphocytic leukemia (B-CLL) cases for which Ig VH and VL gene sequences were available. The cases were categorized based on V gene mutation status and CD38 expression and analyzed for treatment history and survival. The B-CLL cases could be divided into 2 groups. Those patients with unmutated V gen...
A recent case report of a child infected with enterohemorrhagic Escherichia coli (EHEC) of serotype O118:H16 in Bavaria, in association with the isolation of a bovine O118 strain on the same farm (A. Weber, H. Klie, H. Richter, P. Gallien, M. Timm, and K. W. Perlberg, Berl. Muench. Tieraerztl. Wochenschr. 110:211-213, 1997), prompted us to investigate the relationship between bovine and human s...
A review is given of a relatively unknown area of the electronic structures of Rydberg radicals. The primary examples of such structures are H , NH4 and H30. The condensed phase existence of the latter 8wo has long been proposed. Mercury amalgams of organic ammonium radicals, R4N, have been reported. Theoretical studies are reported on some of these species. in liquid ammonia vis-a-vis NH4 + e ...
Direct measurements of vector boson pair production processes and trilinear gauge boson couplings have been conducted by the CDF and DØ Collaborations. Preliminary results from searches for anomalous WW/WZ → μν jet jet and WZ → eeeν production are presented. 95% CL anomalous coupling limits from previously published DØ results are −0.20 < λ < 0.20 (∆κ = 0) and −0.30 < ∆κ < 0.43 (λ = 0) for Λ = ...
Sweet sorghum juice (SSJ) is considered a good carbon source for biorefinery due to its low price and high fermentable-sugar content. In this study, 2,3-butanediol (2,3-BD) production from SSJ by Serratia marcescens H30 was investigated. First, the medium compositions including the contents of SSJ, nitrogen source, and mineral salts were optimized in conical flasks using a single factor and ort...
This study examines the effects of taxes on the real exchange rate through their marginal impacts on economic activity. We develop a model that shows that an increase in the capital interest tax rate leads to real domestic currency depreciation while an increase in wage or consumption tax rates lead to a real domestic currency appreciation. These theoretical findings are supported by an empiric...
BACKGROUND Fluoroquinolone-resistant Escherichia coli are increasingly prevalent. Their clonal origins--potentially critical for control efforts--remain undefined. METHODS Antimicrobial resistance profiles and fine clonal structure were determined for 236 diverse-source historical (1967-2009) E. coli isolates representing sequence type ST131 and 853 recent (2010-2011) consecutive E. coli isol...
The energetics, geometrical and electronic structure, ionization processes, dynamics, and dissociation pathways of neutral and singly and doubly ionized water dimers are investigated with simulations employing the BomOppenheimer local-spin-density functional molecular dynamies (BO-LSD-MD) method. Vertical and adiabatic ionization potentials and dissociation energies and barriers are calculated ...
مقدمه: نویز و رزولوشن فضایی به عنوان پارامترهای مهم در تعیین کیفیت تصاویر توموگرافی کامپیوتری (ct scan) تحت تاثیر پارامترهای مختلفی از جمله کرنل های بازسازی تصویر قرار دارند. کرنل های مختلف به منظور کاهش نویز و یا افزایش شدت در لبه ها استفاده می شوند که هر کدام از آن ها کاربردهای کلینیکی خاص خود را دارند. در این تحقیق تاثیر فیلترهای مختلف بازسازی تصویر بر روی نویز و رزولوشن فضایی بررسی خواهد شد...
