Acute right ventricular failure caused by concomitant coronary and pulmonary embolism: successful treatment with endovascular coronary and pulmonary thrombectomy.

Patent foramen ovale (PFO) is present in approximately 25% of the general population. PFO is characterized by intermittent shunting of blood from the right to the left atrium, especially in the context of increased right-sided filling pressures, with risk of paradoxical embolism. We describe a 69-year-old woman presenting with acute chest pain, severe dyspnoea, and acute inferolateral ST-segment e

Pulse pressure strongly predicts cardiovascular disease risk in patients with type 2 diabetes from the Swedish National Diabetes Register (NDR).

OBJECTIVES: To analyze pulse pressure (PP) as a risk predictor for coronary heart disease (CHD), stroke and cardiovascular disease (CVD; CHD and/or stroke) in type 2 diabetic patients. METHODS: A total of 11,128 female and male type 2 diabetic patients with known baseline PP values and no CVD, aged 50-74 years, were followed for a mean duration of 5.6 years (1998-2003). A subgroup of 5521 patients

Optical microscopy in photosynthesis

Emerging as well as the most frequently used optical microscopy techniques are reviewed and image contrast generation methods in a microscope are presented, focusing on the nonlinear contrasts such as harmonic generation and multiphoton excitation fluorescence. Nonlinear microscopy presents numerous advantages over linear microscopy techniques including improved deep tissue imaging, optical sectio

Bile stimulates Cell Surface Hydrophobicity, Congo Red Binding and Biofilm Formation of Lactobacillus strains.

Seventeen Lactobacillus strains were tested for cell surface hydrophobicity (CSH) using the salt aggregation test (SAT) and Congo red binding (CRB) assay. CRB was pH and ionic strength dependent and protease sensitive and in the presence of 100 μg/ml cholesterol, the CRB was significantly reduced. Autoaggregating (AA) L. crispatus strains showed 50% more CRB than the reference strain, the curli-pr

In situ structure-activity correlation experiments of the ruthenium catalyzed CO oxidation reaction

The complex structure-activity correlation of the CO oxidation on ruthenium has been studied in a batch reactor by using in situ surface X-ray diffraction (SXRD) and on-line mass spectrometry. Two distinct active phases are identified at higher pressures in the mbar range depending on the reaction conditions: a non-oxidic phase and a RuO2(1 1 0) layer of variable thickness ranging from 1.5 nm to 1

Intraspecific Kleptoparasitism in the Common Coot (Fulica atra)

In late fall and early winter > 2,000 Common Coots (Fulica atra) may gather on the small, shallow Lake Krankesjon in southern Sweden, where they dive for submerged plants. Casual observations indicated that intraspecific kleptoparasitism was common throughout these flocks. Kleptoparasitic attacks mostly occurred shortly after a Common Coot surfaced with food and before it had ingested much of it.

An approach to the utilisation of CO2 as impregnating agent in steam pretreatment of sugar cane bagasse and leaves for ethanol production.

ABSTRACT: BACKGROUND: The conditions for steam pretreatment of sugar cane bagasse and leaves were studied using CO2 as an impregnating agent. The following conditions were investigated: time (5 to 15 min) and temperature (190 to 220 degrees C). The pretreatment was assessed in terms of glucose and xylose yields after enzymatic hydrolysis and inhibitor formation (furfural and hydroxymethylfurfural)

The conserved WW-domain binding sites in Dystroglycan C-terminus are essential but partially redundant for Dystroglycan function

Background: Dystroglycan (Dg) is a transmembrane protein that is a part of the Dystrophin Glycoprotein Complex (DGC) which connects the extracellular matrix to the actin cytoskeleton. The C-terminal end of Dg contains a number of putative SH3, SH2 and WW domain binding sites. The most C-terminal PPXY motif has been established as a binding site for Dystrophin (Dys) WW-domain. However, our previous

Swedish version of the multi dimensional health assessment questionnaire - translation and psychometric evaluation.

Health assessment measurements for patients with Rheumatoid arthritis (RA) have to be meaningful, valid and relevant. A commonly used questionnaire for patients with RA is the Stanford Health Assessment Questionnaire Disability Index (HAQ), which has been available in Swedish since 1988. The HAQ has been revised and improved several times and the latest version is the Multi Dimensional Health Asse

"Mitt i evigheten" : Gestaltningen av den moderna naturvetenskapens kosmos i Peter Nilsons Stjärnvägar

“In the middle of eternity”. Representation of the Cosmos of Modern Science in Peter Nilson’s Stjärnvägar. In this article, I analyse Peter Nilson’s essay book Stjärnvägar. The book is about the world view of modern science, and my point of departure is the question of how perspectives and theories from modern science are represented. In Stjärnvägar, Nilson repeatedly refers to the book itself as

Glomerular filtration rate-estimating equations for patients with advanced chronic kidney disease

Renal function is often estimated using one of several glomerular filtration rate (GFR) estimating equations. However, there is no consensus which estimating equation performs best in patients with advanced renal failure. We compared the performance of five different estimated GFR (eGFR) equations [Cockcroft-Gault, Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease (CKD) Epidemio

Search for scalar top quark pair production in natural gauge mediated supersymmetry models with the ATLAS detector in pp collisions at root s=7 TeV

The results of a search for pair production of the lighter scalar partners of top quarks ((t) over bar (1)) in 2.05 fb(-1) of pp collisions at root s = 7 TeV using the ATLAS experiment at the LHC are reported. Scalar top quarks are searched for in events with two same flavour opposite-sign leptons (e, mu) with invariant mass consistent with the Z boson mass, large missing transverse momentum and j

Ensuring quality in studies linking cancer registries and biobanks

The Nordic countries have a long tradition of providing comparable and high quality cancer data through the national population-based cancer registries and the capability to link the diverse large-scale biobanks currently in operation. The joining of these two infrastructural resources can provide a study base for large-scale studies of etiology, treatment and early detection of cancer. Research p
