Objective: To evaluate risk factors - notably drugs - for developing acute pancreatitis. Methods: A population-based, case-control study, encompassing 1.4 million inhabitants aged 20-85 years from four regions in Sweden between 1 January 1995 and 31 May 1998. A total of 462 cases were hospitalised in surgical departments with their first episode of acute pancreatitis without previously known bilia

Calcitonin gene-related peptide (CGRP) and related peptides may be involved in migraine pathogenesis. To understand their vasomotor role in the cerebral circulation, we performed two studies, a pressurized arteriography study of the middle cerebral artery (MCA) and a genuine closed cranial window (gCCW) in vivo study. Using the pressurized arteriography model rat MCAs were mounted on micropipettes

BACKGROUND: Chondromalacia patellae is a potentially disabling disorder characterised by features of patellar cartilage degradation. OBJECTIVE: To evaluate markers of cartilage and bone turnover in patients with chondromalacia patellae. METHODS: 18 patients with chondromalacia patellae were studied. Serum cartilage oligomeric matrix protein (s-COMP) and bone sialoprotein (s-BSP) levels were measur

A total of 301 adult questing Ixodes ricinus ticks were collected at 15 different locations along the south and east coasts of Sweden to determine the Borrelia genospecies diversity. Thirty-two ticks (11%) were found to be positive by nested PCR with Borrelia burgdorferi sensu lato-specific primers. Species determination was based on partial sequencing of the 16S rRNA gene and the flagellin gene.

This paper presents a new method to derive the tire forces for simultaneous braking and cornering, by combining empirical models for pure braking and cornering using brush-model tire mechanics. The method is aimed at simulation of vehicle handling, and is of intermediate complexity such that it may be implemented and calibratedby the end user. The brush model states that the contact patch between

Aqueous extracts of blue-green algae were fractionated by electrofocusing. In all algae investigated, fractions with isoelectric points at or near 4.6 showed photochromic behavior analogous to that of phytochrome, although they were sensitive to light of shorter wavelength. Three main types of photochromic pigments were found. Phycochrome a (in Tolypothrix distorta, Phormidium luridium, Nostoc mus

The distribution of sediment-dispersed extraterrestrial chromite grains and other Cr-rich spinels (> 63 mu m) has been studied in Middle Ordovician Orthoceratite Limestone from two quarries at Kinnekulle, southern Sweden. In the Thorsberg quarry, all similar to 3.2 m thick sequence of beds previously shown to be rich in fossil meteorites is also rich in sediment-dispersed extraterrestrial chromite

This study describes, in quantitative terms, the effects of endothelin-2 and endothelin-3 on vascular tone (resistance) in large-bore arterial resistance vessels (> 25 microns), small arterioles (< 25 microns) and the veins, as well as on capillary pressure and fluid exchange in cat gastrocnemius muscle in vivo. Infusion of endothelin-2 or endothelin-3 (200-1600 ng kg-1 min-1, i.a.) elicited an in

Background: People of low socioeconomic status have worse health and a higher probability of being granted a disability pension than people of high socioeconomic status. It is also known that public and private general physicians and public and private specialists have varying practices for issuing sick leave certificates ( which, if longstanding, may become the basis of disability pensions).
