Endosymbiotic bacteria of aphids, Buchnera aphidicola, and tsetse flies, Wigglesworthia glossinidia, are descendents of free-living gamma-Proteobacteria. The acceleration of sequence evolution in the endosymbiont genomes is here estimated from a phylogenomic analysis of the gamma-Proteobacteria. The tree topologies associated with the most highly conserved genes suggest that the endosymbionts form
Epoxy alkylstearates were synthesized by lipase catalysed esterification and perhydrolysis followed by epoxidation of oleic acid in a one-pot process. Immobilized Candida antarctica lipase (Novozym 435) was used as the catalyst. The esterification reaction occurred relatively quickly and was followed by epoxidation of the alkyl ester and the remaining fatty acid. Higher degree of esterification wa
BACKGROUND: Metabolic syndrome (MS) is a common health problem in menopausal women. According to The Adult Treatment Panel (ATP) III, MS includes the combination of three or more of the following risk factors: abdominal obesity, glucose intolerance, high blood pressure, high serum triglycerides and low levels of high density lipoprotein cholesterol. OBJECTIVES: To assess the prevalence of the MS i
ATP-sensitive potassium (K-ATP) channels play an important role in the regulation of cerebral vascular tone. In vitro studies using synthetic K-ATP channel openers suggest that the pharmacological profiles differ between rat basilar arteries and rat middle cerebral arteries. To address this issue, we studied the possible involvement of endothelial K-ATP channels by pressurized arteriography after
The relation between the atrioventricular conduction properties of the atrioventricular node and the anterograde conduction ability over the accessory pathway in the Wolff-Parkinson-White syndrome has never been studied. Atrioventricular nodal characteristics were studied in 285 patients with manifest and 204 with concealed accessory pathway who underwent radiofrequency ablation, and compared with
A surface with periodic corrugations of sufficiently small periodicity is shown to be electromagnetically equivalent to an inhomogeneous transition region (slab). Explicit expressions for the inhomogeneous transition region are found for one-dimensional corrugations and for two-dimensional corrugations a local elliptic problem has to be solved in order to find the equivalent electromagnetic propertie
Purpose. To gain an understanding of how women with spinal cord injury ( SCI) experienced human encounters in occupations and how these influenced their participation. Method. The data were collected through two or three in- depth interviews with 13 women ( age 25 - 61 years) with SCI. Data analysis was carried out by using a paradigmatic analysis of narrative data, followed by an interpretation b
We have used density functional methods to calculate fully relaxed potential energy curves of the seven lowest electronic states during the binding of O-2 to a realistic model of ferrous deoxyheme. Beyond a Fe-O distance of similar to 2.5 Angstrom, we find a broad crossing region with five electronic states within 15 kJ/mol. The almost parallel surfaces strongly facilitate spin inversion, which is
Objective To evaluate whether N-acetyleysteine (NAC) infusion during the first week of life reduces the risk of death or bronchopulmonary dysplasia (BPD in infants with extremely low birth weight. Study design In a Nordic multicenter, double-blind trial, infants (n = 391) weighing 500 to 999 g and on ventilator or nasal continuous positive airway pressure were randomized before the age of 36 hours
BACKGROUND: Although the true benefits and disadvantages of prostate cancer screening are still not known, the analysis of fatal cases is important for increasing knowledge of the effects of prostate cancer screening on mortality. Who dies from prostate cancer despite participation in a population-based prostate-specific antigen (PSA) screening program? METHODS: From the Goteborg branch of the Eur
In previous work we have demonstrated increased expression of NOX2 in cardiomyocytes of infarcted human hearts. In the present manuscript we investigated the functional role of NOX2 in ischemically challenged H9c2 cells, a rat cardiomyoblast cell line, and adult rat cardiomyocytes. Expression of NOX2 in H9c2 cells was confirmed by RT-PCR. In Western-blot experiments, increased NOX2 expression was
It has been shown that the gene ERG in 21q22 is rearranged in the the t(16;21)(p11;q22) associated with acute myeloid leukemia (AML). ERG is a member of the ETS gene family and is fused with EWS in a subset of Ewing's sarcomas. EWS in 22q12 has a very high homology with FUS (also called TLS) in 16p11; the latter gene is rearranged in the t(12;16)(q13;p11) that characterizes myxoid liposarcoma. To
The aim was to investigate patients and therapists perception of receiving and giving dialectical behavioral therapy (DBT). Ten deliberate self-harm patients with borderline personality disorder and four DBT-therapists were interviewed. The interviews were analyzed with qualitative content analysis. The patients unanimously regard the DBT-therapy as life saving and something that has given them a
The objective of this article is to report and discuss the changing point prevalence rate of neurosis 1947-1997 in the Lundby cohort. The Lundby Study is a prospective longitudinal study of a geographically defined total population in the south of Sweden. Field investigations were performed in 1947, 1957, 1972 and in 1997, with psychiatrists interviewing the probands in a semi-structured way. Addi
