Cholesterol depletion impairs vascular reactivity to endothelin-1 by reducing store-operated Ca2+ entry dependent on TRPC1.

The reactivity of the vascular wall to endothelin-1 (ET-1) is influenced by cholesterol, which is of possible importance for the progression of atherosclerosis. To elucidate signaling steps affected, the cholesterol acceptor methyl-ß-cyclodextrin (mßcd, 10 mmol/L) was used to manipulate membrane cholesterol and disrupt caveolae in intact rat arteries. In endothelium-denuded caudal artery, contract

Rapidly rotating Bose-Einstein condensates in anharmonic potentials

Rapidly rotating Bose-Einstein condensates confined in anharmonic traps can exhibit a rich variety of vortex phases, including a vortex lattice, a vortex lattice with a hole, and a giant vortex. Using an augmented Thomas - Fermi variational approach to determine the ground state of the condensate in the rotating frame - valid for sufficiently strongly interacting condensates - we determine the tra

Suitability of Gamma, Chi-square, Weibull, and Beta distributions as synthetic unit hydrographs

Most available methods for synthetic unit hydrograph (SUH) derivation involve manual, subjective fitting of a hydrograph through a few data points. Because of this tedious procedure, the generated unit hydrograph is often left unadjusted for unit runoff volume. During recent decades, use of probability distribution functions (pdfs) in developing SUH has received much attention because of its simil

Reformationens huvudfrågor och arvet från Augustinus. En studie i Martin Chemnitz' Augustinusreception

Popular Abstract in Swedish Reformationens budskap brukar karakteriseras med hjälp av några "allena": Kristus allena, tron allena, nåden allena och Skriften allena. I denna studie undersöks hur Martin Chemnitz (1522-86) behandlar dessa teman och hur han sätter dem i relation till Augustinus teologi. Martin Chemnitz var en av de mest framstående evangeliska teologerna i generationen efter Martin LuAs a co-author of the Formula of Concord, Martin Chemnitz (1522-86) codified the sola scriptura principle of the Reformation, that the prophetic and apostolic Scriptures are the only rule for all Church doctrine. This principle is clearly expressed in Chemnitz' own theological treatises as well, but in his argumentation one is also confronted with an astonishing number of quotations from the Churc

Inclusive b decays to wrong sign charmed mesons

The production of wrong sign charmed mesons b --> (D) over bar X-(s), D-(s) = (D-0, D+, D-s), is studied using the data collected by the DELPHI experiment in the years 1994 and 1995. Charmed mesons in Z --> b (b) over bar events are exclusively reconstructed by searching for the decays D-0 --> K(-)pi(+), D+ --> K(-)pi(+)pi(+) and D-s(+) --> phipi(+) --> K(+)K(-)pi(+). The wrong sign contribution i

Contractility of human leg lymphatics during exercise before and after indomethacin

Subcutaneous lymphatics in the lower leg were catheterized in the retrograde direction in 6 healthy male subjects. The catheter was connected to a pressure transducer, and pressure was measured during three stages of exercise including standing, tip-toeing, and running in place. Before the third stage, indomethacin (50mg) was given i.v. Rhythmic pressure waves were registered in each subject. Duri

The expression of lymphocyte surface antigens in bronchial biopsies, bronchoalveolar lavage cells and blood cells in healthy smoking and never-smoking men, 60 years old

In this study we investigated if smoking subjects with a normal or slightly decreased lung function differ in the lymphocyte pattern compared to never-smokers. In a group of 'healthy' smokers (n = 58) and never-smokers (n = 34) 60 years old, we investigated the lymphocyte pattern in both BAL (n = 30 and n = 18 respectively), bronchial epithelium and lamina propria (n = 14 and n = 10 respectively)

Interventions for portal hypertension in patients with portal vein occlusion and possible effects of a stent-graft on hepatic circulation

Symptomatic portal hypertension (PH), is often treated by transjugular intrahepatic portosystemic shunt (TIPS). Patients with PH, caused by prehepatic portal vein occlusion, require recanalization with stent or stent-graft often followed by additional TIPS. Stent-grafts used for TIPS, may occlude the outflow from the adjacent hepatic vein, potentially disturbing the circulation through the adjoini

Clinical aspects of delta infection

The clinical features of delta infection were analysed retrospectively in 191 hepatitis B surface antigen (HBsAg) carriers and 592 cases of acute hepatitis B seen over 11 years in the Swedish town of Malmo (population 250 000). With a few exceptions delta infections occurred exclusively in drug addicts. In the chronic HBsAg-carriers the most common clinical manifestation was an episode of acute he

Transition probabilities and lifetimes for atoms and ions from the sixth row of the periodic table and the database DESIRE

We have started a systematic investigation of the radiative properties of the elements of the sixth row of the periodic table. Using a combination of experimental radiative lifetimes obtained with the time-resolved laser-induced fluorescence (LIF) technique and of theoretical branching fractions (BF) calculated with a HFR approach taking configuration interaction and core-polarization effects into

Diversity of desmosomal proteins in regenerating epidermis: immunohistochemical study using a human skin organ culture model

We recently established a skin organ culture model for epithelial healing by creating a central defect in freshly excised human skin specimens and keeping them in culture for up to 7 days, either untreated or with transplantation of allogenic or autologous keratinocytes. In this study the molecular diversity of cell-cell junction proteins in the regenerating epidermis was analysed immunohistochemi

Redetermination of the hyperfine structure of the 6p^(2)P_(3/2) level in Cs 133 by the zero field optical double resonance method

By combining recent level crossing data with the results from a modified atomic beam experiment by Buck, Rabi, and Senitzky in 1956, a Landégj factor deviating about 0.6% from the LS-value -1.3341 is obtained for the 6p2P3/2 level of Cs133. As this large deviation is difficult to explain, a remeasurement of the hyperfine structure of this level was performed by the zero field optical double resona

Classification and diagnostic prediction of cancers using gene expression profiling and artificial neural networks

The purpose of this study was to develop a method of classifying cancers to specific diagnosticcategories based on their gene expression signatures using artificial neural networks (ANNs).We trained the ANNs using the small, round blue-cell tumors (SRBCTs) as a model. These cancersbelong to four distinct diagnostic categories and often present diagnostic dilemmas in clinicalpractice. The ANNs corr

Factors influencing route choice by avian migrants: A dynamic programming model of Pacific brant migration

We used stochastic dynamic programming to investigate a spectacular migration strategy in the black brant Branta bernicla nigricans, a species of goose. Black brant migration is well suited for theoretical analysis since there are a number of existing strategies that easily can be compared. In early autumn, almost the entire population of the black brant gathers at Izembek Lagoon on the Alaska Pen

Effects of tiagabine, a gamma-aminobutyric acid re-uptake inhibitor, on normal rat bladder function.

PURPOSE: Previous reports have demonstrated the inhibitory effect of exogenous gamma-aminobutyric acid (GABA) on micturition. In the current study we tested whether tiagabine (Sanofi Synthelab., Newcastle-upon Tyne, United Kingdom), a GABA re-uptake inhibitor increasing endogenous GABA concentrations, would affect micturition in awake rats or influence rat detrusor contraction in vitro. MATERIALS

Cytogenetic and fluorescence in situ hybridization characterization of clonal chromosomal aberrations and CCND1 amplification in esophageal carcinomas

Cytogenetic analyses of four squamous cell carcinomas (SCC) of the esophagus showed complex numerical and structural abnormalities. Chromosomal bands or regions preferentially involved were 11q13, 8q10, 21q10, 3p10similar top11, 1p11similar toq11, 5p11similar toq11, and 14p11similar toq11. For the first time, to our knowledge, recurrent aberrations were identified in esophageal SCC, including homo
