- We present range telescopes for measurements of low energy K+ mesons together with first in-beam results. The hardware trigger, based on the observation of the mu(+) from the K+ --> mu(-) + nu(mu) decay channel, is designed for subthreshold hadron-nucleus

- Subthreshold K+ production cross sections have been measured in symmetric Ne + NaF, Ni + Ni, and Au + Au collisions at 1.0A GeV. The mass dependence is strong, close to A(2). The angular distributions are nonisotropic in the center-of-mass system. Introdu

- Iron in amphibole asbestos is implicated in the pathogenicity of inhaled fibers. Evidence includes the observation that iron chelators can suppress fiber-induced tissue damage. This is believed to occur via the diminished production of fiber-associated re

High prevalence of thyroid autoantibodies at diagnosis of insulin-dependent diabetes mellitus in Swedish children
- 1997

Tidskriftsartikel (refereegranskat)abstract
- The prevalence of thyroglobulin autoantibodies and that of thyroid peroxidase autoantibodies were studied in serum samples from 52 children with insulin-dependent diabetes mellitus, sampled at diagnosis and before the start of insulin treatment, with 386 non-diabetic schoolchildren (11 to 13 years of age) serving as control subjects. Using exactly the same sensitive solid-phase immunosorbent radioassay for both thyroid autoantibodies, with comparable sensitivity, we found the prevalences of both autoantibodies to be higher in the insulin-dependent diabetes mellitus group than in the control group, the difference being most pronounced for thyroid peroxidase autoantibodies. Thyroglobulin autoantibodies were positive in 33% of the diabetics versus 14% in the control group (p = 0.002), and thyroid peroxidase autoantibodies were positive in 38% versus 6% (p = 0.0001). The high prevalence of thyroid autoantibodies already at diagnosis stresses the importance of early screening for thyroid disease in patients with insulin-dependent diabetes mellitus.

- OBJECTIVE: This study was designed to determine whether a relationship exists between previous exposure to measles, mumps, and rubella (MMR) by natural infection or vaccination or by new immunization with MMR vaccine, and either the presence or levels of autoantibodies against thyroid cell and pancreatic beta-cell antigens. METHODS: Antibodies against MMR and autoantibodies against thyroglobulin, thyroid peroxidase, pancreas islet cells (ICA), islet cell surface, glutamic acid decarboxylase 65k autoantibodies, and insulin were studied before, and 3 months after, vaccination with combined MMR vaccine in 386 school children between 11 and 13 years of age. RESULTS: The vaccination changed neither the prevalence nor the level of autoantibodies. Children with rubella antibodies before vaccination had higher levels of ICA than did the rubella seronegative children. In contrast, thyroid autoantibody levels and prevalence were lower in children with antibodies against measles, mumps, or both before vaccination than in children without those antibodies. CONCLUSIONS: Previous natural infection or vaccination against measles, mumps, or both seemed to have an inhibitory effect on the development of thyroid autoantibodies. In contrast, children with previous exposure to rubella had higher levels of ICA. No evidence was found that MMR vaccination during adolescence may trigger autoimmunity.

Mineralfiberfragment och 'sjuka hus'-besvär i skolmiljö
- 1995
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Lärare på flera skolor i Göteborg har kopplat irritation av slemhinnor, främst i ögonen, till miljön i skolorna. En hypotes har framlagts att besvären skulle kunna bero på mineralfibermaterial. Besvären antas inte bero på hela fibrer i luften utan på sönderdelade fibrer, fragment. En studie har gjorts för att kartlägga eventuella samband mellan halten mineralfiberfragment, mätt som bl a kisel, i luften på skolor och förekomsten av sjuka hus-besvär, speciellt ögonirritation, bland skolpersonalen. Resultatet av studien är att inga signifikanta positiva samband mellan symptom och totaldammhalten och halterna kisel, kalcium eller järn kunde påvisas. Den specifika hypotesen att mineralfiberfragment skulle vara orsaken till ögonbesvär i skolmiljö har därmed inte kunnat beläggas, eftersom inga positiva samband mellan lufthalten av kisel, kalcium eller järn (som alla förekommer i mineralull) och sjuka hus-besvär kunnat påvisas. Detta motsäger dock inte att mineralfibrer i vissa fall, i andra miljöer än de här undersökta och under exponeringsbetingelser, skulle kunna bidra till sjuka hus-besvär.
