- In the Swedish vascular registry 7473 carotid endarterectomies are registered, in 10% the indication being a symptomatic stenosis. There are great variations in indication for carotid endarterectomy within Sweden. During the last five years the combined postoperative mortality and/or postoperative permanent stroke has varied between 3% in 1999 and 1.5% in 2003. During the same period not a single patient operated on for a symptomatic carotid stenosis experienced these complications.

Perpendicular magnetocrystalline anisotropy in tetragonally distorted Fe-Co alloys

- We report on the experimental realization of tetragonal Fe-Co alloys as a constituent of Fe(0.36)Co(0.64)/Pt superlattices with huge perpendicular magnetocrystalline anisotropy energy, reaching 210 mu eV/atom, and a saturation magnetization of 2.5 mu(B)/atom at 40 K, in qualitative agreement with theoretical predictions. At room temperature the corresponding values 150 mu eV/atom and 2.2 mu(B)/atom are achieved. This suggests that Fe-Co alloys with carefully chosen combinations of composition and distortion are good candidates for high-density perpendicular storage materials.

Synthesis and biological evaluation of reversible inhibitors of IdeS, a bacterial cysteine protease and virulence determinant

- Analogues of the irreversible protease inhibitors TPCK and TLCK have been synthesized and tested as inhibitors of the bacterial cysteine protease IdeS excreted by Streptococcus pyogenes. Eight compounds were identified as inhibitors of IdeS in an in vitro assay. The most potent compounds contained an aldehyde function, thus acting as efficient reversible inhibitors, nitrile and azide derivatives showed moderate activity. (C) 2009 Elsevier Ltd.

- OBJECTIVES: In the past few decades, clinical presentation in AMI has been reported to be changing, with milder cases and less ST-elevation myocardial infarction, the most serious form of AMI. The better outcome may be due to improved medical and interventional management, as well as more sensitive methods for detecting AMI. However, changes in risk factors have also been documented, especially lower tobacco-smoking rates. Therefore, the relation between smoking and ST-elevation AMI in a large observational cohort was analysed. METHODS: Data were derived from 93 416 consecutive patients aged 25 to 84 years and admitted to hospital between 1996 and 2004 with a first AMI. RESULTS: Tobacco smoking was more prevalent in younger patients (ie, <65 years). More than 50% of younger patients presenting with STEMI were smokers at the time of hospitalisation. After multiple adjustments, smoking was found to be an independent determinant for presenting with STEMI compared with non-STEMI. The adjusted odds ratio (OR) associated with smoking was 2.01 (99% CI 1.75 to 2.30) in younger women and 1.33 (99% CI 1.22 to 1.43) in younger men, with a significant interaction between smoking and gender. In older women and men (> or =65 years), the corresponding ORs were 1.33 (99% CI 1.20 to 1.48) and 1.14 (99% CI 1.04 to 1.25), respectively. CONCLUSION: Tobacco smoking is a major determinant for presenting with STEMI compared with non-STEMI, particularly among younger patients and among women. These results indicate that smoking is one of the major risk factors for presenting with more severe AMIs.

IgG glycan hydrolysis by a bacterial enzyme as a therapy against autoimmune conditions.

- EndoS from Streptococcus pyogenes efficiently hydrolyzes the functionally important and conserved N-linked glycan of IgG in human blood. Repeated i.v. administration of EndoS in rabbits completely hydrolyzes the glycans of the whole IgG pool, despite the generation of anti-EndoS antibodies. EndoS administration had no apparent effects on the health of the animals. EndoS hydrolysis of the IgG glycan has profound effects on IgG effector functions, such as complement activation and Fc receptor binding, suggesting that the enzyme could be used as an immunomodulatory therapeutic agent against IgG-mediated diseases. We demonstrate here that EndoS indeed has a protective effect in a mouse model of lethal IgG-driven immune (or idiopathic) thrombocytopenic purpura. EndoS pretreatment of pathogenic antibodies inhibits the development of disease, and the enzyme also rescues mice from already established disease when severe thrombocytopenia and s.c. bleeding have developed. These results identify EndoS as a potential therapeutic agent against diseases where pathogenic IgG antibodies are important and further emphasize antibody glycans as possible targets in future therapies against antibody-mediated autoimmune conditions.

Storminess variation during the last 6500 years as reconstructed from an ombrotrophic peat bog in Halland, southwest Sweden

- Cores taken from an ombrotrophic peat bog in the coastal zone of Halland, southwest Sweden, were examined for wind transported mineral grains, pollen and humidity indicators. The core covers the period from 6500 cal. yr BP to present. Ombrotrophic conditions existed from ca. 4200 cal. yr BP onwards. Bog surface wetness fluctuated strongly until ca. 3700 cal. yr BP, with an apparent dominance of dry summer conditions from 4800-4500 cal. yr BP. Local wet shifts occurred around 4300, 2800, 2400 and 1500 cal. yr BP, whereas the most recent 600 years of the record show increasingly dry conditions. Mineral grain content, interpreted as aeolian sand influx (ASI), was used as a proxy for (winter) storm frequency and intensity until ca. 1500 cal. yr BP, after which increasing human impact, as reconstructed by pollen analysis, became a second important potential cause for increased sand drift. Strongly increased storminess occurred at 4800, 4200, 2800-2200, 1500, 1100 and 400-50 cal. yr BP, indicating a dominance of cold and stormy winters during these periods. Many of these storm periods apparently coincide with storm events in other sites in southwestern Scandinavia, suggesting that our ASI record reflects a regional scale climatic signal. Furthermore these stormy periods correlate to well-known cold phases in the North Atlantic region, suggesting a link to large-scale fluctuations in atmospheric circulation patterns.
