Laboratories throughout the world that perform work with Risk Group 4 Pathogens generally adopt one of two approaches within BSL-4 environments: either the use of positive pressure air-fed suits or using Class III microbiological safety cabinets and isolators for animal work. Within the UK at present, all laboratories working with Risk Group 4 agents adopt the use of Class III microbiological s...

The microbiological contamination of operating theatres and the lack of adherence to best practices by surgical staff represent some of the factors affecting Surgical Site Infections (SSIs). The aim of the present study was to assess the microbiological quality of operating settings and the staff compliance to the SSI evidence-based control measures. Ten operating rooms were examined for microb...

OBJECTIVE To determine the frequency of microbiological contamination of water in different water filtration plants in Islamabad. STUDY DESIGN Descriptive cross-sectional study. PLACE AND DURATION OF STUDY Water Filtration Plants (WFP) in different sectors of Islamabad, from April to September 2012. METHODOLOGY Water samples were collected in sterilized bottles according to the standard w...

Microbiological analysis allows us to identify the etiology of pneumonia and its in vitro susceptibility pattern. Antibiotic treatment directed against a known pathogen enables us to narrow antibacterial spectrum of action, and to reduce costs, drug adverse effects risk and antibiotic resistance. However it is unnecessary to perform extended microbiological studies in all patients with communit...

BACKGROUND AND OBJECTIVE The present study is aimed to describe short-term results on selected microbiological and clinical parameters obtained by treatment with soft laser in conjunction with methylene blue and/or mechanical subgingival debridement in human periodontal disease. STUDY DESIGN/MATERIALS AND METHODS Ten patients, in whom each dental quadrant was randomly designated to receive on...

Diagnosis of vaginal discharge is frequently performed in an empirical way, leading to inadequate treatment. This study tested the accuracy of a self-collection kit for microbiological study of the vaginal content. One hundred and forty-two women of Family Health Program units in Niterói and Piraí cities were enrolled in order to have their vaginal content studied. A brief explanation and a sel...

OBJECTIVE Microbiological examination of donated human cardiac tissue is a necessary procedure for Heart Valve Banks to determine the biological safety of preserved allografts. Test protocols must be validated to prevent false-negative outcomes that pose a risk of infection to recipients of the tissue. The Heart Valve Bank in Rotterdam evaluated a validated, alternative entry test for donated t...

In this paper we propose a method for implementing a high-level interface for the synthesis and animation of animated virtual faces that is in full compliance with MPEG-4 specifications. This method allows us to implement the Simple Facial Object profile and part of the Calibration Facial Object Profile. In fact, starting from a facial wire-frame and from a set of configuration files, the devel...

A g-element for a graded R-module is a one-form with properties similar to a Lefschetz class in the cohomology ring of a compact complex projective manifold, except that the induced multiplication maps are injections instead of bijections. We show that if k(∆) is the face ring of the independence complex of a matroid and the characteristic of k is zero, then there is a non-empty Zariski open su...

Using the “glueball dominance” picture of the mixing between qq̄ mesons of different hidden flavors, we establish new glueball-meson mass relations which serve as a basis for glueball spectral systematics. For the tensor glueball mass 2.3 ± 0.1 GeV used as an input parameter, these relations predict the following glueball masses: M(0) ≃ 1.65 ± 0.05 GeV, M(1) ≃ 3.2 ± 0.2 GeV, M(2) ≃ 2.95 ± 0.15 G...
