BACKGROUND: Selective cerebral perfusion (SCP) is used for extending the period during which surgical procedures can be safely performed. We sought to determine the direct effects of pH management on cerebral microcirculation and metabolism during SCP. METHODS: An experimental SCP porcine model was created by selectively allowing cold perfusate only into the bicarotid brachiocephalic trunk during

The most prominent poets in the two golden ages of Swedish Poetry in the 19th Century are presented: Tegnér, Stagnelius, von Heidenstam,Fröding, Karlfeldt. Their formal skills as well as their main themes are described, and citations are given in english and swedish.

Background: Low-grade fibromyxoid sarcoma (LGFMS) is an uncommon neoplasm with bland morphology and an indolent clinical course, although metastases may develop in approximately 5-10% of the cases. The diagnosis of LGFMS can be difficult to render from fine needle aspiration cytology (FNAC) alone because of morphological overlap with other spindle cell and myxoid lesions. Objective: To determine c

Objective: Following the Ross operation, pulmonary autografts tend to dilate over time. This study researches the fate of the pulmonary autograft - at 4.5 years following the modified Ross operation - with special reference to the impact of the modification on (a) pulmonary autograft dilatation, (b) the neo-aortic root geometry, (c) neo-aortic valve function and (d) the coronary artery reserve. Me

A survey, admittedly selective and personal, of the literature of research into various aspects of the history of the book in Sweden from 1990. With bibliographical notes.

Structural compromise of the tumor suppressor gene, PTEN occurs in 10% of melanoma specimens and loss of PTEN expression through DNA methylation of the PTEN promoter region has also been reported in a number of other malignancies. However, the role of PTEN promoter methylation in melanoma is not well understood. We thus sought to elucidate the prevalence of PTEN promoter methylation in melanoma sp

Based on the assumed strain method, a simple four-node axisymmetric solid element is introduced. The assumed strain field is carefully selected to preserve the correct rank of the element stiffness matrix and to achieve high accuracy. The strain field is developed in conjunction with orthogonal projections and no matrix inversions are needed. The coarse mesh accuracy in bending and in typical axis

OBJECTIVE: It has been estimated that alcohol drinking increases the risk of breast cancer in women by approximately 7% for each increment of 10 g alcohol per day. However, the few studies conducted on breast cancer among men have failed to detect an association with quantitative measures of alcohol drinking, even if the alcohol intake is generally higher in men than in women. On the other hand, i

Objective. To investigate the relationship between carpal tunnel syndrome (CTS) and keyboard use at work in a general population. Methods. A health status questionnaire was mailed to 2,465 persons of working age (25-65 years) who were randomly selected from the general population of a representative region of Sweden. The questionnaire required the subjects to provide information about the presence

The next generation of telescopes, the Extremely Large Telescopes (ELTs), will have a multitude Of control loops to maintain nearly diffraction-limited performance in the presence of atmospheric turbulence and external disturbances, for instance from wind. Integrated simulation models combining structural and optical modeling together with control system modeling are efficient tools for prediction

A stochastic model for the HCCI engine is presented The model is based on the PaSPFR-IEM model and accounts for inhomogeneities in the combustion chamber while including a detailed chemical model for natural gas combustion, consisting of 53 chemical species and 590 elementary chemical reactions. The model is able to take any type of inhomogeneities in the initial gas composition into account, such

BACKGROUND: The role of long-acting, inhaled beta2-agonists in treating asthma is uncertain. In a double-blind study, we evaluated the effects of adding inhaled formoterol to both lower and higher doses of the inhaled glucocorticoid budesonide. METHODS: After a four-week run-in period of treatment with budesonide (800 microg twice daily), 852 patients being treated with glucocorticoids were random

The Tartoq Group, located in SW Greenland, consists of supracrustal rocks of mainly tholeiitic basaltic composition, including pillow lavas, sills/dykes and gabbros, as well as ultramafic rocks. Metamorphic grade ranges from greenschist fades to granulite facies. The Tartoq Group crops out as a series of blocks and slivers that are imbricated with originally intrusive Mesoarchaean TTG orthogneisse

Background and Purpose-Secondary prevention is recommended after stroke, but adherence to guidelines is unknown. We studied the prescription of antiplatelet drugs, angiotensin-converting enzyme inhibitors, statins, and anticoagulant drugs and their relation to risk of death. Methods-Patients with first-ever ischemic stroke in 2005 were registered in the Swedish Stroke Register. Odds ratios, hazard

Objective. This study evaluated the impact of hospital volume on local recurrence and distant metastasis in a population-based series of radical cystectomy patients in Sweden. Material and methods. All patients who underwent cystectomy for bladder cancer in 1997-2002 in Sweden and were reported to the National Bladder Cancer Registry were included. A high-volume hospital (HVH) was defined as one w

BACKGROUND: Established risk factors for pancreatic cancer include smoking, long-standing diabetes, high body fatness, and chronic pancreatitis, all of which can be characterised by aspects of inflammatory processes. However, prospective studies investigating the relation between inflammatory markers and pancreatic cancer risk are scarce. METHODS: We conducted a nested case-control study within th
