New chemostratigraphic data through the Mulde Event interval (Silurian, Wenlock), Gotland, Sweden

The Mid-Silurian (Wenlock) Mulde Event is a globally recognised faunal turnover and extinction event affecting pelagic fauna as well as shallow marine benthos. Time-equivalent strata in the carbonate platform succession of Gotland, Sweden reveal marked changes in the compositions of reefs and the formation of chemical and microbial carbonates in the early aftermath of the extinctions. New high-res

Use of incisional negative pressure wound therapy on closed median sternal incisions after cardiothoracic surgery: clinical evidence and consensus recommendations.

Abstract Negative pressure wound therapy is a concept introduced initially to assist in the treatment of chronic open wounds. Recently, there has been growing interest in using the technique on closed incisions after surgery to prevent potentially severe surgical site infections and other wound complications in high-risk patients. Negative pressure wound therapy uses a negative pressure unit and s

Can high psychological job demands, low decision latitude, and high job strain predict disability pensions? A 12-year follow-up of middle-aged Swedish workers.

OBJECTIVES: The aim of this study was to investigate whether job strain, psychological demands, and decision latitude are independent determinants of disability pension rates over a 12-year follow-up period. METHODS: We studied 3,181 men and 3,359 women, all middle-aged and working at least 30 h per week, recruited from the general population of Malmö, Sweden, in 1992. The participation rate was

Contact sensitization to calocephalin, a sesquiterpene lactone of the guaianolide type from cushion bush (Leucophyta brownii, Compositae)

BackgroundCushion bush [Leucophyta brownii Cass.=Calocephalus brownii (Cass.) F. Muell.] is an Australian Compositae shrub that has been introduced into Scandinavia as a pot plant. The first case of sensitization occurred in a gardener, and the main allergen was identified as the guaianolide calocephalin. ObjectiveTo present the identification of the main allergen, and to assess the prevalence of

Thoughts and experiences from returning to work after stroke.

Objective: The aim of this study was to increase the understanding of stroke survivors' thoughts and experiences from returning to work after stroke. Methods: Semi-structured interviews were carried out with twelve persons, based on a thematic interview guide. A qualitative content analyse were performed. Results: The main theme; was Striving for optimal function at work creates mixed feelings of

The Swedish economy in the early modern period: constructing historical national accounts

A new GDP series per capita for Sweden during 15601800 is presented, linked to slightly revised data for 18002000. Long-term stagnation up to the nineteenth century is revealed but with secular changes. Growth characterized much of the seventeenth century with modernization of state administration, industry and trade. In the next century, stagnation and even retrogression followed. Wars in the sev

Summary of the recommendations of the EFNS/MDS-ES review on therapeutic management of Parkinson's disease

Objective: To summarize the 2010 EFNS/MDS-ES evidence-based treatment recommendations for the management of Parkinson's disease (PD). This summary includes the treatment recommendations for early and late PD. Methods: For the 2010 publication, a literature search was undertaken for articles published up to September 2009. For this summary, an additional literature search was undertaken up to Decem

Acceptance of Background Noise, Working Memory Capacity, and Auditory Evoked Potentials in Subjects with Normal Hearing

Background: The acceptable noise level (ANL) test is a method for quantifying the amount of background noise that subjects accept when listening to speech. Large variations in ANL have been seen between normal-hearing subjects and between studies of normal-hearing subjects, but few explanatory variables have been identified. Purpose: To explore a possible relationship between a Swedish version of

Can the APO method be used for measuring soft data?: A pilot study.

Objectives. The aims were to develop auditing according to the APO (Audit Project Odense) method for measuring soft data, exemplified by a holistic view, and to test the instrument. Design. A descriptive study of the development of an APO chart and a test registration. Setting. Primary health care, Blekinge County, Sweden. Subjects. Ten general practitioners (GPs) were invited to transform categor

Local recurrence and progression of non-muscle-invasive bladder cancer in Sweden: a population-based follow-up study.

Abstract Objective. The aim of this study was to investigate recurrence and progression of non-muscle-invasive bladder cancer (NMIBC) in a large population-based setting. Materials and methods. Patients with bladder cancer (stage Ta, T1 or carcinoma in situ) diagnosed in 2004-2007 (n = 5839) in Sweden were investigated 5 years after diagnosis using a questionnaire. Differences in time to recurrenc

AKT and AMPK Activation after High-Fat and High-Glucose In Vitro Treatment of Prostate Epithelial Cells.

Considering the increasing consumption of saturated fat and glucose in diets worldwide and its possible association to carcinogenesis, this investigation analysed the proliferation profile of nonmalignant human prostate epithelial cells after exposure to elevated levels of fat and glucose. PNT1A cells were cultured with palmitate (100 or 200 μM) and/or glucose (450 mg/dl) for 24 or 48 h. Treated c

Sensitivity of high-resolution Arctic regional climate model projections to different implementations of land surface processes

This paper discusses the effects of vegetation cover and soil parameters on the climate change projections of a regional climate model over the Arctic domain. Different setups of the land surface model of the regional climate model HIRHAM were realized to analyze differences in the atmospheric circulation caused by (1) the incorporation of freezing/thawing of soil moisture, (2) the consideration o

Mean square error optimal weighting for multitaper cepstrum estimation

The aim of this paper is to find a multitaper-based spectrum estimator that is mean square error optimal for cepstrum coefficient estimation. The multitaper spectrum estimator consists of windowed periodograms which are weighted together, where the weights are optimized using the Taylor expansion of the log-spectrum variance and a novel approximation for the log-spectrum bias. A thorough discussio

Large area buffer-free graphene on non-polar (001) cubic silicon carbide

Graphene is, due to its extraordinary properties, a promising material for future electronic applications. A common process for the production of large area epitaxial graphene is a high temperature annealing process of atomically flat surfaces from hexagonal silicon carbide. This procedure is very promising but has the drawback of the formation of a buffer layer consisting of a graphene-like sheet

Sexual abuse and associations with psychosocial aspects of health. A population- based study with Swedish adolescents.

Background: Few population-based Nordic studies with adolescents investigate the associations between sexual abuse (SA) and psychosocial health. Aim: Associations between adolescents' self-reported experiences of SA different severity and aspects of psychosocial health such as emotional and behavioral problems, sense of coherence and self-esteem (general comment: sense of coherence=the theoretical

New pregaliellalactonoids from Galiella rufa

An extract of a culture of the fungus Galiella rufa yielded several new derivatives of pregaliellalactone (1) that were characterised by NMR and MS experiments. The tetraene 4 has been reported previously, but was in this investigation isolated in sufficient amounts for the determination of the configuration of the C-4/C-5 double bond which is Z, not E. The possibility that any of the new compound
