Effects of organic solvents on motor activity in mice

Groups of male mice were exposed via inhalation to methylene chloride, perchloroethylene, toluene, trichloroethylene or 1,1,1-trichloroethane. The exposures were started at 2300 h. Generation of vapor was stopped after 1 h. Motor activity of the animals during the exposures was measured with a Doppler radar. Several concentrations of each solvent were tested. Concentrations could be found for all

Assessments of PSA Forms and hK2 as Very Early Predictors of Prostate Cancer

Popular Abstract in Swedish Prostatacancer är den bland män vanligast förekommande cancerformen i Sverige. Under 2003 diagnostiserades 9882 nya fall. Sjukdomen drabbar framför allt äldre individer; många män är 70 år gamla eller äldre när de får diagnosen. Sjukdomsförloppet kan vara mycket varierande. Hos många är tumörtillväxten långsam, men sjukdomen kan också utvecklas snabbt. Många patienter lConcentrations of prostate-specific antigen (PSA) and human kallikrein 2 (hK2) were investigated in blood samples that had been obtained from men who were diagnosed with prostate cancer (PCa) decades later. The studies were based on a cohort comprising 22,444 men who, in 1974?1986, were early middle aged and represented a non-PCa-screened population. The results clearly demonstrate a very strong c

SHBG gene promoter polymorphisms in men are associated with serum sex hormone-binding globulin, androgen and androgen metabolite levels, and hip bone mineral density

Context: SHBG regulates free sex steroid levels, which in turn regulate skeletal homeostasis. Twin studies have demonstrated that genetic factors largely account for interindividual variation in SHBG levels. Glucuronidated androgen metabolites have been proposed as markers of androgenic activity. Objective: Our objective was to investigate whether polymorphisms in the SHBG gene promoter [(TAAAA)(n

Clinicians' management strategies for patients with dyspepsia: a qualitative approach

Background: Symptoms from the upper gastrointestinal tract are frequently encountered in clinical practice and may be of either organic or functional origin. For some of these conditions, according to the literature, certain management strategies can be recommended. For other conditions, the evidence is more ambiguous. The hypothesis that guided our study design was twofold: Management strategies

Arbetslöshet ekonomi och skam : Om att vara arbetslös i dagens Sverige

Popular Abstract in Swedish Avhandlingen syftar till att undersöka arbetslöshetens sociala konsekvenser och försöka ge en rimlig tolkning av variationer i arbetslöshetserfarenheter med hjälp av en teoretisk modell - ekonomi-skam modellen. Fokus ligger på att söka lyfta fram och visa på betydelsen av ekonomiska påfrestningar i kombination med skamupplevelser som en faktor för att förstå skillnader The purpose of this study has been to investigate the social consequences of unemployment and to give a possible interpretation of unemployment experiences through the application of the economy-shame model. It intends to put forward and show the significance of economic stress in combination with the feeling of shame as a factor important for the understanding of differences in unemploy-ment expe

Frontal lobe dysfunction in long-term cannabis users

This study examined the neurophysiological effects of cannabis. Cerebral blood flow (CBF) was measured in 12 long-term cannabis users shortly after cessation of cannabis use (mean 1.6 days). The findings showed significantly lower mean hemispheric blood flow values and significantly lower frontal values in the cannabis subjects compared to normal controls. The results suggest that the functional l

C6 peptide ELISA test in the serodiagnosis of Lyme borreliosis in Sweden

The aim of this study was to evaluate the synthetic C6 peptide test as a first-line test in a two-tiered scheme for Borrelia serology in a clinically well-characterized population of patients with Lyme borreliosis in Kalmar County, Sweden. The study population consisted of a prospective group (n=200), a control group (n=255), and a retrospective group (n=29). The test panel consisted of the Immune

Numerical Simulation of Some Heat Transfer and Fluid Flow Phenomena for Gas Turbine Blades and a Transonic Turbine Stage

With the attempts to achieve higher thermal efficiency, turbine blades are exposed to very high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is important to obtain a good understanding of both the complex flow field and the heat transfer characteristics in turbine rotor/stator hot-gas passa

Kontroversen om arbetstidsförkortning : en sociologisk studie av tre försök med arbetstidsförkortning inom Malmö kommun

I denna rapport redovisas dels en övergripande bild över arbetstidsförkortningsdebatten och dels tre försöksprojekt med arbetstidsförkortning som bedrevs under ett och ett halvt år i Malmö kommun. Det hävdas att debatten har utvecklats till en kontrovers i vilken olika grupperingar av debattaktörer kan urskiljas utifrån sina ställningstaganden till reformen, och att det kunskapsunderlag som finns

Photodissociation of Bromobenzene in Solution.

The photodissociation of bromobenzene in solution was investigated with ultrafast transient absorption spectroscopy following excitation at 266 nm. Ab initio calculations of lower singlet and triplet states were performed in order to guide the interpretations. The main feature of the kinetics measured between 300 and 930 nm in acetonitrile is a 9±1 ps decay, which we mainly assign to predissociati

Proton and Electron Microprobe Analysis of Human Skin

In order to demonstrate the feasibility of the proton microprobe in the analysis of dermatological material when a spatial resolution of a few micrometres is sufficient and to compare it with the electron microprobe technique, duplicate sections of human skin have been analysed with both methods. A skin sample was obtained from each of three healthy volunteers. After cryosectioning (12 μm) and fre
