Background: Several studies have shown impaired mental well-being and performance in physicians work on call, but knowledge of the physiological effects is scarce. The aims of the present study were to investigate if there was a metabolic stress response in the restitutional phase after night-call duty, indicating potential negative health effects, and determine whether there were differences betw

We used exposure to microwaves from a global system for mobile communication (GSM) mobile phone (915 MHz, specific absorption rate (SAR) 37 mW/kg) and power frequency magnetic field (50 Hz, 15 mu T peak value) to investigate the response of lymphocytes from healthy subjects and from persons reporting hypersensitivity to electromagnetic field (EMF). The hypersensitive and healthy donors were matche

In recent years, the question of what determines compliance with international regulatory agreements has gained an increasingly prominent position on the research agenda through a burgeoning literature on international regime effectiveness and international legal systems. The contemporary debate is framed in terms of two alternative perspectives on compliance: enforcement or management. The two pe

Objective: The aim of this study was the validation of the criteria defining a significant mucocutaneous-bleeding history in type 1 von Willebrand disease (VWD). Subjects and methods: To avoid selection bias, 42 obligatory carriers (OC) of type 1 VWD were identified from a panel of 42 families with type 1 VWD enrolled by 10 expert centers. OC were identified by the presence of an offspring and ano

BACKGROUND.: We conducted this prospective longitudinal multicenter study to evaluate the health-related quality of life (HRQL) of patients with oral carcinoma at diagnosis, and after 1 and 5 years in relation to tumour location and treatment modality. METHODS.: One hundred twenty-two patients (mean age, 61; 62% males) with oral carcinoma were evaluated with standardized HRQL questionnaires, the E

Both increase of the glucose concentration and activation of purinoceptors are known to affect pancreatic alpha-cells. Effects obtained with various purino derivatives at 2.8 and 8.3 mmol/ liter glucose have been taken to indicate that external ATP is less potent than adenosine as a stimulator of glucagon release. However, when making a corresponding comparison at 20 mmol/ liter glucose, we observ

The objective of this study was to evaluate estimated and measured donor renal function in predicting graft function long-term and to identify donor criteria associated with nonacceptable graft prognosis. In 200 consecutive cadaver donors creatinine clearance was measured at explantation and estimated using the Cockcroft formula on admission serum creatinine. Graft function was evaluated in recipi

Studies were performed in guinea pigs to elucidate alterations in endogenous uterine norepinephrine (NE) levels and changes in the contractile response to exogenous NE following local sympathetic denervation, oophorectomy, or treatment with sex steroids. Both in intact and oophorectomized animals the myometrial NE concentration was reduced after sex steroid treatment (0.5 microgram 17-beta-estradi

Introduction: The systemic inflammatory response syndrome (SIRS) may be initiated by a number of underlying conditions such as acute pancreatitis. The association between the local inflammatory reaction, the systemic response, and potential concomitant dysfunction of remote organs is not quite clear. Aim: To evaluate whether severe acute pancreatitis in the rat affects energy metabolism in the pan

Lysozyme (Lyz), chymotrypsinogen (Cht), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were used as model proteins capable of forming water-soluble polyelectrolyte complexes with linear synthetic polyanions. The complex formation with sodium poly(methacrylate) (PMA), sodium poly(acrylate) (PAA), sodium poly(anetholsulfonate) (PAS), and potassium poly(vinylsulfate) (PVS) markedly reduced the

An experimental investigation has been carried out to find the flow and the pressure difference across the port to channel in plate heat exchangers for a wide range of Reynolds number. 1000-17000. In the present study, low corrugation angle plates have been used for different number of channels, namely, 20 and 80. Water has been used as working fluid for both hot and cold fluids. The pressure prob

OBJECTIVES: To retrospectively investigate the use of percent free prostate-specific antigen (PSA) compared with total PSA in serum as predictor of prostate cancer in men selected randomly from the general population who underwent biopsy on the basis of abnormal findings on digital rectal examination (DRE) or transrectal ultrasound (TRUS) and/or serum PSA levels greater than 10 ng/mL. METHODS: A s

ABA triblock copolymers having benzimidazole-tethered end blocks have been prepared and characterized with respect to their intrinsically proton conducting properties. The copolymers were synthesized by using a linear poly(ethylene oxide) (PEO) as a difunctional macroinitiator for the anionic ring-opening polymerization of allyl glycidyl ether. The pendent allyl groups of the end blocks were subse

Box jellyfish, or cubomedusae (class Cubozoa), are unique among the Cnidaria in possessing lens eyes similar in morphology to those of vertebrates and cephalopods. Although these eyes were described over 100 years ago, there has been no work done on their electrophysiological responses to light. We used an electroretinogram ( ERG) technique to measure spectral sensitivity of the lens eyes of the C

A population-based serosurvey of Human Herpesvirus type 8 (HHV8) in Vasterbotten county, an area of Northern Sweden with high incidence of Kaposi's Sarcoma, was conducted. Serum samples from an age- and sex-stratified random sample of 520 subjects (260 men and 260 women) participating in a population-based biobanking project were tested for antibodies against HHV8, using a sensitive indirect immun
