Glucose oxidase (GOD) kinetics comprises a group of inhibitory, deactivant and diffusional phenomena interacting with each other in a complex way. These phenomena have given rise to differing interpretations, and their description is hindered by studies at moderate glucose concentrations (usual condition in many applications of the enzyme), the presence (or absence) of catalase in the enzymatic...

the objective of this study was to assess the microbial contamination of razavi khorasan (iran) hot red pepper. the natural occurrence of aflatoxins and ochratoxin a in those samples was also investigated. for this purpose, 36 samples of this kind of pepper were collected from a farm and sun-dried. standard and established methods were used for both microbiological analyses and mycotoxins ident...

Vancomycin-resistant urinary tract infections are often challenging to treat. This retrospective cohort study compared outcomes between patients treated for vancomycin-resistant enterococcal urinary tract infection with an aminopenicillin and those treated with a non-β-lactam antibiotic. Inpatients treated with an enterococcus-active agent for their first symptomatic vancomycin-resistant entero...

The Berkeley FrameNet Project1 has been engaged since 1997 in discovering and describing the semantic and distributional properties of words in the general vocabulary of English.2 Notions from FRAME SEMANTICS (see Fillmore and Baker 2009 and references therein) provide the basis of the semantic description of the lexical units in the database, and sentences extracted from the FrameNet (FN) text...

Patients admitted to the hospital with pulmonary infi ltrates were empirically treated with high dose oseltamivir (150 mg 2×/d) for 5 days, other antimicrobial drugs, and, eventually, steroids. In 2 patients, the respiratory disease progressed initially but they eventually recovered; 2 patients (1.2% of admissions to hospital) with acute respiratory failure died. Despite improvement in clinical...

In this paper are described some properties of emergent phenomena and situations that appear in complex systems. The basic factors for the understanding to emergent processes are: the level of realization and the description of the emergent process, sharp change of the system structure (in our case represented by the violence of a structural invariant), a self-organizing phenomenon (that forms ...

BACKGROUND We performed a systematic review and meta-analysis of short- vs long-duration antibiotic regimens for ventilator-associated pneumonia (VAP). METHODS We searched PubMed and Cochrane Central Registry of Controlled Trials. Four randomized controlled trials (RCTs) comparing short (7-8 days) with long (10-15 days) regimens were identified. Primary outcomes included mortality, antibiotic...

We present a characterization of the main properties of the night-sky at the Calar Alto observatory for the time period between 2004 and 2007. We use optical spectrophotometric data, photometric calibrated images taken in moonless observing periods, together with the observing conditions regularly monitored at the observatory, such as atmospheric extinction and seeing. We derive, for the first ...
