MR characteristics of acute cholangitis

Purpose: To describe the MR appearance of acute cholangitis and discuss the role of MR imaging as a diagnostic method in this disease. Material and Methods: Of 60 patients with clinical acute cholangitis, 12 were examined with MR before endoscopic retrograde pancreatography (ERCP). A retrospective review was performed of MR and ERCP findings. The MR findings registered were presence of biliary duc

Action of matrix metalloproteinases at restricted sites in colon anastomosis repair: an immunohistochemical and biochemical study

Background. Dehiscence of colon anastomosis is a common, serious and potentially life-threatening complication after colorectal operation. In experimental models, impaired biomechanic strength of colon anastomoses is preventable by general inhibitors of matrix metalloproteinases (MMPs) and associated with collagen loss, which indicates a possible link between MMP-mediated collagen degradation and

Higher urinary IgM excretion in type 2 diabetic nephropathy compared to type 1 diabetic nephropathy.

BACKGROUND: Proteinuria, due to impairment of the charge- and/or size selectivity of the glomerular capillary wall (GCW) is the earliest clinical evidence of diabetic nephropathy (DN). To study the pathophysiological differences between patients with DN in type 1 diabetes mellitus (type 1 DN) and type 2 diabetes mellitus (type 2 DN), we compared the patterns of urinary proteins of different size a

A numerical and experimental study of initial defibration of wood

A major drawback of the defibration or refining process in manufacturing pulp is that of its large energy requirements. If the mechanics of the process were better understood, large amounts of energy could probably be saved. The initial defibration seems to be crucial for both the quality of the pulp and the total consumption of energy. Numerical simulations by means of the finite element method r

Moult and moult migration of Greylag Geese Anser anser from a population in Scania, south Sweden

The moult migration of Greylag Geese Anser anser from Scania, southernmost Sweden, was studied based on resightings of neck-banded individuals marked in the breeding areas. Most geese seen in moulting areas were recorded in the marking area both before and after moult. Lip to 1992, 72% of all neck-banded Greylag Geese recorded front a moulting area were reported from Oostvaardeusplassen in the Net

SPI-C, a PU-box binding ETS protein expressed temporarily during B-cell development and in macrophages, contains an acidic transactivation domain located to the N-terminus.

Mice deficient for SPI-group ETS transcription factors PU.1 or SPI-B fail to generate lymphocytes or do not mount normal antibody mediated immune responses, respectively. PU.1 expression is restricted to B-, T-lymphocytes and macrophages, while SPI-B is expressed in B- and T-lymphocytes. SPI-C is an ETS transcription factor closely related to PU.1 and SPI-B, and expressed temporarily during B-cell

Barriers to the use of electroconvulsive therapy in the elderly: a European survey

A postal survey was carried out to determine the clinical and legal guidelines governing the use of electroconvulsive therapy (ECT) in the countries of the wider Europe. Respondents from 23 of the 33 countries returned completed questionnaires. Considerable variation was found in the availability of ECT, the frequency of its use and associated legal procedures. However, there was a broad consensus

Visualization of Guidelines on Computer Networks to Support Processes of Design and Quality Control

Popular Abstract in Swedish För att tillverka produkter av hög kvalitet, behöver industriella företag strukturera arbetet med hjälp av instruktioner och riktlinjer som är lätta att förstå och komma åt. Dessa samlas ofta i en eller flera pärmar eller på internt datornätverk, ofta som en del av den internationella kvalitetsstandarden ISO 9000. Men detta fungerar sällan som ett välfungerande stöd förIndustrial companies supply products intended to satisfy customers’ needs and requirements. To be competitive and to maintain good economic performance, efficient systems are needed to communicate information and exchange knowledge. Such systems are often referred to as quality systems as they intend to support development as well as standardized work regarding the quality of the product and incre

Fully stapled gastric bypass with isolated pouch and terminal anastomosis: 1-3 year results.

BACKGROUND: Roux-en-Y gastric bypass is a bariatric procedure of choice. There is evidence supporting a small isolated pouch and a wide anastomosis. Gastric vascular anatomy renders the ventral aspect less suited for anastomotic construction. The lesser curvature has abundant blood supply that should preferably not be interfered with. Terminal anastomosis is a logical choice. METHODS: We devised a

The Swedish graduate school in mathematics education: Concep-tion, birth and development of a new doctoral programme

In this paper we trace the establishment of the graduate school in mathematics education in Sweden. To provide a useful context for this initia-tive we review briefly the evolution of the PhD, the development of doctoral degrees and doctoral programmes in mathematics departments in Sweden, as well as the growing popularity of graduate schools. Progress and pro-gramme issues encountered to date are

Sensationellt valresultat i Indiens folkrikaste delstat

Efter tre års så kallad djungelregim (jungle raj) under Mulayam Singh Yadavs ledning, återkommer nu dalitledaren Mayawati till makten på eget mandat i Uttar Pradesh, Indiens folkrikaste delstat. I det utdragna valet, vars resultat blev klart den 11 maj 2007, vann hon och hennes parti Bahujan Samaj Party (BSP) en absolut majoritet med 206 mandat i delstatförsamlingen.

Conservation principles suspended solids distribution modelling to support ATS introduction on a recirculating WWTP

A model for the description of the SS distribution in a full-scale recirculating activated sludge WWTP was developed. The model, based on conservation principles, uses on-line plant data as model inputs, and provides a prediction of the SS load in the inlet to the secondary clarifiers and the SS distribution in the WWTP as outputs. The calibrated model produces excellent predictions of the SS load

The ability of white-rot fungi to degrade the endocrine-disrupting compound nonylphenol

Phanerochaete chrysosporium, Pleurotus ostreatus, Trametes versicolor and Bjerkandera sp. BOL13 were tested for their ability to degrade the endocrine-disrupting compound nonylphenol at an initial concentration of 100 mg l–1. The highest removals were achieved with T. versicolor and Bjerkandera sp. BOL13, which were able to degrade 97 mg l–1 and 99 mg l–1 of nonylphenol in 25 days of incubation, r

Plasma oxidized LDL: a predictor for acute myocardial infarction?

Objectives. Oxidized LDL has been attributed a key role in the development of atherosclerosis. Previous studies have demonstrated increased plasma levels of oxidized LDL in patients with established coronary artery disease. The aim of the present study was to investigate if plasma oxidized LDL also predicts risk for development of coronary heart disease (CHD). Design. We used a nested case-contro

Chemical and Clinical Studies of Isocyanate Contact Allergy with focus on diphenylmethane diisocyanate

Popular Abstract in Swedish I detta arbete studerades olika aspekter av lapptestdiagnostiken vid misstänkt kontaktallergi mot en grupp ämnen som kallas isocyanater. Dessa ämnen innehåller reaktiva isocyanatgrupper med den kemiska strukturen -N=C=O. Isocyanater används framförallt vid tillverkningen av polyuretan (PUR) som bildas när iso-cyanater reagerar med flerfunktionella alkoholer till en polyIsocyanates are highly reactive compounds used in the production of polyurethane. Exposure to isocyanates is mainly associated with respiratory disorders, but may also result in allergic contact dermatitis. Reports describing contact allergy to isocyanates are few in number and it has been considered a rare phenomenon. In the present study it is shown that the low frequency of reported cases could

X-ray data on the temporal coordination of speech gestures

Preliminary results are reported from a study of speech gestures analyzed from an x-ray motion film of a southern Swedish speaker. The gestures analyzed here are taken from one utterance from the film. Frame-by-frame analysis of the presence or absence of articulator movement provided information about temporal coordination & segmental simultaneity & sequencing. The data suggest challenges

Transmission rates and phenotypic effects of mitochondrial plasmids and cytotypes in Silene vulgaris

We investigated the transmission properties and the phenotypic effects of two mitochondrial plasmids in a population of the bladder campion, Silene vulgaris. In reciprocal crosses between plasmid-free and plasmid-carrying plants, no cases of paternal transmission or loss during maternal transmission were recorded. Neither was any transmission via pollen observed when plasmid-carrying plants of S,
