The activity of Ro 19-5247 (the active metabolite of the oral cephalosporin Ro 19-5248 [T-2588]) was compared with that of five orally active agents against a total of 331 bacterial strains. Ro 19-5247 was more active in vitro than amoxicillin, amoxicillin-clavulanate, cefaclor, cefuroxime, and cephalexin against members of the family Enterobacteriaceae. Amoxicillin-clavulanate and amoxicillin ...
In order to quantify the plant species diversity characteristics of Pinus massoniana plantations with different stand densities in Danjiangkou reservoir area Hubei Province and relationship their trade-offs synergies water retention capacity give full play forest ecosystem services improve level sustainable management plantations, we used typical plot method, selected 35-year-old low density (9...
Abstract Adolescent young carers have been described as a hidden group at risk of mental health problems. However, research has not yet clarified the effect caring when considering related family situation. We aimed to examine impact role on adolescents’ and gain knowledge about adolescent carers’ specific needs. collected cross-sectional data from adolescents (15–21 years, N = 2525) recruited ...
Head and neck cancer patients presenting with distant metastases are generally considered incurable. Treatment patterns and survival by primary disease site and therapy have not been described. Retrospective cohort analysis of 2525 patients in the National Cancer Database (2003-2006). Kaplan-Meier and Cox proportional hazards analyses were performed. Combined locoregional and systemic therapy w...
BACKGROUND To understand the relationship between the Staphylococcus aureus infection rate and the reasonable usage of antibiotics, which will help in the effective control of MRSA infection. METHODS All data were obtained by the application of the nosocomial infection surveillance network. Drug resistance, departmental sources, and isolated sites as well as infection rate variations of S. au...
By single crystal NMR the nuclear quadrupole coupling constants eQ,.h~ (H), the asymmetry parameters >/(H) and the dircetion cosines of the principal axes of the electric field gradient tensors of the H atoms of the two kinds of D 2 0 molecules have been determined at 295 K in RbAl(S04)2 • 1 2 D 2 0 . The results show that the D 2 0 molecules surrounding the ion Al + are "static" within the ...
The proximal region of chromosome 15 is one of the genomic hotspots for copy number variants (CNVs). Among the rearrangements observed in this region, CNVs from the interval between the common breakpoints 1 and 2 (BP1 and BP2) have been reported cosegregating with autism spectrum disorder (ASD). Although evidence supporting an association between BP1-BP2 CNVs and autism accumulates, the magnitu...
OBJECTIVE To characterise the nature of the sport injury prevention literature by reviewing published articles that evaluate specific clinical interventions designed to reduce sport injury risks. DATA SOURCES PubMed, Cinahl, Web of Science and Embase. MAIN RESULTS Only 139 of 2525 articles retrieved met the inclusion criteria. Almost 40% were randomised controlled trials and 30.2% were coho...
This contribution addresses filtering requirements to meet the ETSI and ANSI specifications on transmit signal power spectral density (PSD) for VDSL systems employing multicarrier modulation techniques. It is shown that the specifications can be met with simple fixed filtering elements. Conformance with the various PSD masks is achieved by proper adjustment of the digital gains at the input of ...
OBJECTIVE To analyse published articles that used interventions aimed at investigating biomechanical/physiological outcomes (ie, intermediate risk factors) for sport injury prevention in order to characterise the state of the field and identify important areas not covered in the literature. DATA SOURCES PubMed, Cinahl, Web of Science and Embase were searched using a broad search strategy. M...
