PURPOSE: Hypoxia is one of the most important factors influencing clinical outcome after radiotherapy. Improved knowledge of factors affecting the levels and distribution of oxygen within a tumor is needed. The authors constructed a theoretical 3D model based on histological images to analyze the influence of vessel density and hemoglobin (Hb) concentration on the response to irradiation.METHODS:

An 80-year old male presented with an infected knee replacement following repeated joint aspirations. They were carried out due to recurrent hemarthrosis resulting from an initially missed quadriceps tendon injury. The infection was eradicated first after arthrodesis. This case highlights that prosthetic joints are sensitive to infection, which once established can be difficult to eradicate. Caref

In The 21st-Century Voice: Contemporary and Traditional Extra-Normal Voice, Michael Edward Edgerton considers contemporary vocal techniques within an acoustic and anatomical framework. Throughout, he proposes new directions for vocal exploration. Much more than a historical treatise on 20th-century masterworks or vocal science, The 21st-Century Voice explores experimental methods of sound producti

Objective. Obsessive-compulsive disorder (OCD) is a heterogeneous condition with well-established symptom dimensions across the lifespan. The objective of the present study was to use network analysis to investigate the internal structure and central features of these dimensions in unselected schoolchildren and in youth with OCD.Method. We estimated the network structure of OCD symptom dimensions

This monograph presents a working description of a special class of acoustical outputs, termed extra-complex sonorities that are the result of desynchronizing robust parameters involved in the production of sound within scaled and multidimensional networks by instruments and voices. The purpose of such a description is to provide a framework for understanding the mechanical and perceptual aspects

This article will present a single case study of the acoustic attributes of sound production techniques that are involved in the expansion of performance practice with the violin. In this study, four elements were chosen from the multidimensional network involved in playing a normal tone, and then each was intentionally decoupled from ordinario. These elements (bow speed, bow placement, bow angle,

I alla vardagliga situationer och relationer gör sig inblandade personers känslor påminda på olika sätt. Det kan få en stor inverkan på utfallet av mänskliga möten i skilda sammanhang. I den ”juridiska världen” har detta länge varit en icke-fråga. Juridiken är till sin natur rationell och objektiv och det gäller juristen också. Så har det sagts. Men detta är av allt att döma en grov förenkling. I

The influence of wind is only occasionally accounted for in fire safety engineering, still the effect of wind on, for example, the performance of a smoke management system can be large. A simple analytical method to account for the effect of wind on mass flow through horizontal openings for natural ventilation is compared to results from CFD simulations in this paper. It is seen that the correspon

Nine participants, representing eight different Swedish fire consultancy firms participated in a Round Robin study where two different fire scenarios were simulated with the Fire Dynamics Simulator. The participants were given clear instructions on the building layout and heat release rate for the two scenarios. Still, the results demonstrate a significant variation in time to sprinkler system act

In 2007, Brandforsk – the Swedish Fire Research Board – initiated a research program to provide an overview of research needs coupled to ”arson” in Sweden. A total of six different Swedish universities and research institutes were involved in different projects in the research program. These projects involved both technical aspects fire detection and fire compartmentation as well as sociological i

BACKGROUND: Orbital morphological changes are often present in patients with Graves' disease (GD) already at diagnosis, and cyclooxygenase type 2 (COX-2) is overexpressed in active Graves' ophthalmopathy (GO).OBJECTIVE: To investigate if adjuvant treatment of GD with the COX inhibitor and peroxisome proliferator-activated receptor-γ (PPAR-γ) antagonist diclofenac decreases the development of ophth

Objectives Pseudomonas aeruginosa is a Gram-negative species that causes chronic and acute infections of the lung, skin, urinary tract and eyes. Most P. aeruginosa isolates are highly resistant to antibiotics and difficult to eradicate due to biofilm formation. The bacterium is known to utilize host proteins by diverse strategies in order to enhance its virulence. Vitronectin is a glycoprotein tha

Bacterial extracellular vesicles (EVs) are shed during growth by the respiratory pathogens Pseudomonas aeruginosa and Haemophilus influenzae. Vesicles trigger release of antimicrobial compounds and proteins of the complement, which are partly regulated by vitronectin. We hypothesized that vitronectin is elevated in the lungs during pneumonia, that respiratory epithelial cells produce vitronectin u
