Wound healing after hand surgery in patients with systemic sclerosis-a retrospective analysis of 41 operations in 19 patients.

t This retrospective study evaluates the results of 41 consecutive hand and forearm operations in 19 patients with systemic sclerosis performed between 1985 and 2000. The mean age of the patients was 50 (14-84) years. Twenty-seven operations were elective and 14 were acute, carried out for skin breakdown and/or skin necrosis. One minor wound healing problem occurred in the elective group. In the

Development of a microtomography system at the Lund sub-micron beamline

A system for ion beam tomography has been implemented in conjunction with the new sub-micron bearriline at the Lund Nuclear Microprobe laboratory. The first version of the system is dedicated to STIM (scanning transmission ion microscopy) tomography for three-dimensional mass density analysis, but future development will allow also PIXE (particle induced X-ray emission) tomography for elemental an

Chaperones and folding of MHC class I molecules in the endoplasmic reticulum.

In this review we discuss the influence of chaperones on the general phenomena of folding as well as on the specific folding of an individual protein, MHC class I. MHC class I maturation is a highly sophisticated process in which the folding machinery of the endoplasmic reticulum (ER) is heavily involved. Understanding the MHC class I maturation per se is important since peptides loaded onto MHC c

Production of functional protein hydrolysates from Egyptian breeds of soybean and lupin seeds

Enzymatic hydrolysis is an agro-processing aid that can be utilized in order to improve nutritional quality of protein extracts from many sources. In this study, protein extracts from ungerminated and/or germinated local Egyptian soybean and lupin flours were hydrolyzed using the enzyme papain. The hydrolysis processes were carried out for 2 h and aliquots were withdrawn at different time interval

A Monte Carlo program for the simulation of scintillation camera characteristics

There is a need for mathematical modelling for the evaluation of important parameters for photon imaging systems. A Monte Carlo program which simulates medical imaging nuclear detectors has been developed. Different materials can be chosen for the detector, a cover and a phantom. Cylindrical, spherical, rectangular and more complex phantom and source shapes can be simulated. Photoelectric, incoher

Concentrations of polychlorinated biphenyls in blood and the risk for testicular cancer

An increasing incidence of testicular cancer has been reported from several western countries during the last decades. According to current hypothesis testicular cancer is initiated during the foetal period and exposure to endocrine disruptors such as some persistent organic pollutants has been of concern. We have previously reported the results for concentrations of polychlorinated biphenyls (PCB

A regulatory polymorphism in PDCD1 is associated with susceptibility to systemic lupus erythematosus in humans

Systemic lupus erythematosus (SLE, OMIM 152700) is a complex autoimmune disease that affects 0.05% of the Western population, predominantly women(1-4). A number of susceptibility loci for SLE have been suggested in different populations, but the nature of the susceptibility genes and mutations is yet to be identified(5-9). We previously reported a susceptibility locus (SLEB2) for Nordic multi-case

Effects of intravenous calcitonin gene-related peptide (CGRP) and substance P on the blood-aqueous barrier in the rabbit

The irritation response of the rabbit eye to trigeminal nerve stimulation, which includes a breakdown of the blood-aqueous barrier (BAB), seems to be due to the release of substance P (SP) and calcitonin gene-related peptide (CGRP). In order to assess the relative importance of these two peptides for the barrier effect, and the role of arachidonic acid metabolites (AAM) in the response, we have st

Blood pressure in middle-aged women: are androgens involved? A population-based study of Swedish women: the Women's Health in the Lund Area study

Objective To assess the prevalence of hypertension and use of antihypertensive drug therapy in relation to menopausal status and to delineate perceived associations between androgens and blood pressure in perimenopausal women. Methods A population- based sample of women aged 50 - 59 ( nU6893). Women were divided into three groups according to their hormonal status: premenopausal, postmenopausal wi

Do you trust your brethren? Eliciting trust attitudes and trust behavior in a Tanzanian congregation

This paper describes one possible method for using subject pools other than undergraduate students. We also report the results from an experiment in which 145 subjects belonging to a specific church in Dar-es-Salaam, Tanzania were exposed to a Trust Game and a standard set of attitudinal survey questions in order to study trust and trustworthiness, two concepts that are likely to be at the core of

Facklig styrka eller reformistisk strategi?

Artikeln ”Facklig styrka eller reformistisk strategi?” publicerades i Zenit nr 4 (nr 86) 1984 som en kommentar till Anders Perssons recension i Zenit nr 2 (nr 84) 1984 av Anders Kjellbergs doktorsavhandling Facklig organisering i tolv länder (Lund: Arkiv förlag 1983). Redaktionen klippte dock av utrymmesskäl bort ett stycke som under rubriken ”Facklig styrka – än en gång!” publicerades i Zenit nr

Reglermöte -85

The workshop Reglermöte 85 was arranged during May 29-30 1985 at the Department of Automatic Control at Lund Institute of Technology. About 100 persons participated evenly divided between industry and universities. 18 papers were presented. Abstracts of the papers are given in the report.

Golvvärme i betonggolv : temperaturfördelningsberäkningar : analys av fuktbalans

Den praktiska tillämpningen av de utförda beräkningarna kan sammanfattas i följande punkter: - Den gynnsamma effekten på uttorkning av byggfukt, som erhålles av mineralullsisolering och slopande av ångspärr, kan lnte utnyttjas vid golvvärme annat än möjligen i undantagsfall. Fukttillförseln underifrån riskeras bli a1ltför stor om golvvärmen stängs av mer än 3 - 4 månader för ett ordinärt småhus. -

Essays on Econometric Theory

This dissertation contains a variety of contributions to econometric theory. Broadly speaking, econometrics may be categorized depending on what type of data is being analyzed, the two main categories being time series data and cross sectional data. A third category is panel data, combining cross sectional data observed over time. This is the area at which this dissertation is aimed. Panel data mo

Curium isotopes in Chernobyl fallout

In nuclear reactors plutonium and transplutonium isotopes are produced by multiple neutron capture of uranium and plutonium and are important for the energy production and their composition reflects the core burnout. Under normal operation these elements are not released to the environment in significant amounts. There are accordingly very few areas or source terms where exotic transplutonium elem

Low umbilical artery vascular flow resistance and fetal outcome.

Background. An abnormally high [above mean + 2 standard deviations (SD)] umbilical artery (UA) pulsatility index (PI) indicates impaired fetal outcome, whereas the impact of an "abnormally" low (below mean -2 SD) PI is unknown. Methods. Perinatal outcome was compared between cases with a UA PI less than mean -2 SD (group A: high-risk cases selected from a database, n = 330; group B: unselected ca
