BACKGROUND Vibration response imaging (VRI) is a bedside technology to monitor ventilation by detecting lung sound vibrations. It is currently unknown whether VRI is able to accurately monitor the local distribution of ventilation within the lungs. We therefore compared VRI to electrical impedance tomography (EIT), an established technique used for the assessment of regional ventilation. METH...

Content security is an important issue in multimedia applications. In this paper we perform a cryptanalysis of several encryption algorithms that have been proposed to protect the privacy of MPEG video streams. In particular, we analyze the encryption based on permuting the Huffman codeword list, and two selective encryption algorithms VEA and MVEA. For the convenience of the reader, we provide...

Patients with a left ventricular assist device (LVAD) and tachycardia (VT) often have subepicardial substrate, which may not be amenable to epicardial ablation due sternotomy-related adhesions the LVAD itself. As an alternative approach, coronary venous ethanol (VEA) can used ablate VT substrates without needing pericardial access. To assess feasibility acute safety of VEA in patients VT. We re...

BACKGROUND In the Czech Republic, two-dose immunization against mumps achieves 98% coverage. The routine reporting detects mumps cases, clinical complications, and hospital admissions in unvaccinated but also in vaccinated individuals. Using surveillance data of patients with mumps we assessed the effectiveness of mumps vaccination on mumps clinical complications and hospitalization need. We al...

An operator T acting on a Banach space X satisfies the property (UWE) if σa(T ) r σSF− + (T ) = E(T ), where σa(T ) is the aproximate point spectrum of T , σ SF− + (T ) is the upper semi-Weyl spectrum of T and E(T ) is the set of all eigenvalues of T that are isolated in the spectrum σ(T ) of T . In this paper, we introduce and study two new spectral properties, namely (VE) and (VEa ), in conne...

Eukaryotes have evolved highly conserved vesicle transport machinery to deliver proteins to the vacuole. In this study we show that the filamentous fungus Aspergillus parasiticus employs this delivery system to perform new cellular functions, the synthesis, compartmentalization, and export of aflatoxin; this secondary metabolite is one of the most potent naturally occurring carcinogens known. H...

The Aspergillus nidulans velvet (veA) gene encodes a global regulator of gene expression controlling sexual development as well as secondary metabolism. We have identified the veA homologue AcveA from Acremonium chrysogenum, the major producer of the beta-lactam antibiotic cephalosporin C. Two different disruption strains as well as the corresponding complements were generated as a prelude to d...

La regulación normativa y la jurisprudencia referente a formalización de práctica prostitución ha tenido avances significativos en el Estado Colombiano. Sin embargo, persisten una serie dificultades que hace ejercicio esta actividad se vea frustrada por falta garantías los derechos, haciendo personas ejercen económica, vean inmersas informalidad históricamente caracterizado labor.

or quinidine. Two dose schedules were employed; procaine amide, 3.0 and 6.0 g daily and quinidine, 1.2 and 1.8 g daily. Though adequate and even high drug blood levels were reached, an effective antiarrhythmic response was observed in only eight patients receiving procaine amide and in seven of those taking quinidine. These modest successful results were associated with a high incidence of trou...
