Carvedilol, an antihypertensive drug with activity on adrenoceptors as well as on calcium channel activity, has recently been introduced. In the present study we investigated whether carvedilol interacts with the cytotoxicity induced by irradiation in vitro as well as in vivo. A daily injection of carvedilol in clinically relevant concentrations (3 mg/kg subcutaneously), 4 days before and 3 days a

Background The Medical School of Lund University, Sweden, has introduced an early patient contact course, including training in communication and examination skills. The course runs parallel with theoretical subjects during the students' first two-and-a-half years. General practitioner (GP) participation is gradually increasing, and in the last half-year of the course GPs in all health centres in

Important characters in the classification of the lichenized familyAlectoriaceae (Lecanorales) are discussed and evaluated. A few associated genera presently accommodated in the familyParmeliaceae (Lecanorales) are also discussed. Characters in the asci and hamathecium are of major importance, but structural characters such as general thallus organization and anatomy of cortical layers must also b

Background and study aim: Small-bowel tumors account for 1%-3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and endoscopic appearance of small-bowel tumors

Objective: to explore the views and experiences of care of lesbian women during pregnancy and childbirth. Design, setting and participants: a qualitative study of 18 lesbian women in southern Sweden. Findings: valid text units were formed through categorisation into four main categories: recognition of sexual orientation; openness; relationships within the homosexual family; and different encounte

Tissue microarray (TMA) is an efficient technique for analysis of molecular markers. Prospectively collected samples have been reported to give excellent concordance between TMA data and corresponding whole-sections. The aim was to evaluate the usefulness of TMA in a population-based cohort of 213 women with ductal carcinoma in situ of the breast (DCIS). We studied immunohistochemical HER2, oestro

According to Swedish legislation (LVM) compulsory treatment shall be decided on if someone, due to ongoing abuse of alcohol, drugs or volatile solvents, is in need of care to overcome abuse and if a voluntary intervention is not possible. Very little research has been conducted in Sweden on this particular legislation with regard to the clients' experiences of entire process from assessment to aft

We demonstrate the assembly of nanoscale ferromagnetic single-electron transistors using atomic force microscopy for imaging as well as for nanoscale manipulation. A single 30 nm Au disc, forming the central island of the transistor, is manipulated with angstrom precision into the gap between a plasma-oxidized Ni source and drain electrodes. The tunnel resistances can be tuned in real time during

Background: Interleukin 1 beta ( IL- I beta) is found in bronchoalveolar lavage fluids from asthmatic patients and plays an important role in normal immunoregulatory processes but also in pathophysiological inflammatory responses. The present study was designed to investigate if IL- I beta could be involved in the development of airway hyperresponsiveness and if transcriptional mechanisms, epithel

Different ways of approximating the exchange-repulsion energy with a classical potential function have been investigated by fitting various expressions to the exact exchange-repulsion energy for a large set of molecular dimers. The expressions involve either the orbital overlap or the electron-density overlap. For comparison, the parameter-free exchange-repulsion model of the effective fragment po

OBJECTIVES: To study whether intrauterine growth restriction (IUGR) is associated with decreased sensitivity to the main fetal growth factor, insulin, and the effect of glucocorticoid therapy on insulin sensitivity in preterm infants. STUDY DESIGN: Newborn infants with a birth weight (BW) of< 1500 g were classified as appropriate for gestational age ([AGA], BW within +/- 1 SD, n = 10), or small fo

The allocation and cycling of carbon (C) within forests is an important component of the biospheric C cycle, but is particularly understudied within tropical forests. We synthesise reported and unpublished results from three lowland rainforest sites in Amazonia (in the regions of Manaus, Tapajos and Caxiuana), all major sites of the Large-Scale Biosphere-Atmosphere Programme (LBA). We attempt a co

The effect of short-and long-term ethanol exposure on bradykinin-stimulated hydrolysis of phosphatidylinositol 4.5-bisphosphate (PIP2) was investigated in neuroblastoma X glioma hybrid cells (NG 108-15). Acute exposure of 50-150 mM ethanol neither influenced the bradykinin-stimulated accumulation of [3H]-inositol phosphates (IP1, IP2, IP3) nor the hydrolysis of PIP2 in cells labelled with [3H]-ino

The authors investigated a possible contextual effect of neighborhood on individual use of hormone replacement therapy (HRT) and antihypertensive medication (AHM) and the impact of neighborhood social participation on individual use of these medications. They attempted to disentangle contextual from individual influences. Multilevel logistic regression modeling was used to analyze data on 15,456 w

In this study, we evaluated the possible use of lentiviral vectors in the treatment of neuropathic pain. We chose to administer GDNF-expressing vectors because of the known beneficial effect of this trophic factor in alleviation of neuropathic pain in adult rodents. Lentiviral vectors expressing either GDNF or control, green fluorescent protein or beta-galactosidase, were injected unilaterally int
