OBJECTIVE: Pharyngeal reflux after a gastric pull-up esophagectomy may cause aspiration. This study evaluates acid exposure to the esophageal remnant and to the pharynx after gastric pull-up esophagectomy and evaluates the impact of additional dissection of the esophagus that is necessary for neck anastomoses versus no neck exploration and proximal chest anastomoses.METHODS: Forty-seven patients h
1. The possibility that the endothelium-derived hyperpolarising factor (EDHF) in the rat hepatic artery is a cytochrome P450 mono-oxygenase metabolite of arachidonic acid was examined in the present study. In this preparation, acetylcholine elicits EDHF-mediated relaxations in the presence of the nitric oxide (NO) synthase and cyclo-oxygenase inhibitors N(ω)-nitro-L-arginine (L-NOARG) and indometh
The maximal production of galactooligosaccharides (GOS) from lactose by (β-glycosidases from the hyperthermophilic archaea, Sulfolobus solfataricus (LacS) (derived from lacS gene) and Pyrococcus furiosus (CelB) (derived from celB gene) was optimized. The performance of these enzymes under extreme reaction conditions, temperatures up to 95°C and lactose concentrations up to 90% (w/v), were studied.
Five hundred thirty-two cases of slipped capital femoral epiphysis (physiolysis colli femoris - PCF) treated at three orthopedic departments in southern Sweden between 1910 and 1982 were used for epidemiologic studies. Three hundred twenty-five cases came from a well-defined area and were used for incidence analyses. During the whole period of investigation, the disease was more common in men than
BACKGROUND: Oral contraceptives are known to reduce the incidence rate of endometrial cancer, but it is uncertain how long this effect lasts after use ceases, or whether it is modified by other factors.METHODS: Individual participant datasets were sought from principal investigators and provided centrally for 27 276 women with endometrial cancer (cases) and 115 743 without endometrial cancer (cont
Under the Sign of Regret focuses on aesthetically mediated responses to regret. It interrogates the qualities of the feeling of regret as well as what is produced under its influence (as objects and as experiences). These two aims—considering regret as a mode and as a tool—hinge between two complementary definitions of aesthetics: on the one hand, the quality of feelings or the “distribution of th
The LHCb experiment, presently under construction at CERN (European Center for Nuclear Research) Large Hadron Collider (LHC), aims at the study of CP violation in the B meson sector. Its key elements will be a Muon detector which allows triggering and muon identification from inclusive b decays. The electronic system of the whole detector is very complex and its Muon detector Experiment Control Sy
A 9-month lab experiment was carried out with three different amendments (vine pruning wastes, PW; composted vine pruning wastes, cPW; and sewage sludge, SS) added at three different rates (90, 180, and 240 t ha−1, dry weight) in order to test whether the type or the quantity of the amendments applied to a semiarid, degraded soil determined the Corg accumulation in its particle-size fractions (coa
We study the process gg → bb̄H+H- at large tanβ, where it represents the dominant production mode of charged Higgs boson pairs in a Type II 2-Higgs doublet model, including the minimal supersymmetric standard model. The ability to select this signal would in principle enable the measurements of some triple-Higgs couplings, which in turn would help understanding the structure of the extended Higgs
Biochar has been extensively studied as a soil amendment for carbon sequestration and for improving soil quality; however, a systematic understanding of the responses of soil microbial biomass and diversity to biochar addition is lacking. Here, a meta-analysis of 999 paired data points from 194 studies shows that biochar increases microbial biomass but has variable effects on microbial diversity.
In this paper we address the energy consumption of the Constraint Application Protocol (CoAP) and the Message Queue Telemetry Transport (MQTT) protocol and compare their overhead. We also pay attention to the use case of security in IoT and analyze the energy consumption when using TLS/DTLS for the two protocols. In our experiments we use ESP32 with libcoap, MQTT, and mbed TLS libraries and conduc
Objective: Chronic renal disease other than scleroderma renal crisis (SRC) is not well documented in systemic sclerosis (SSc). We examined the occurrence of decreased glomerular filtration rate (GFR) in a large consecutive SSc cohort and analysed whether it was related to SSc or could be related to other causes. Methods: During 1983-2004 GFR was measured by chromium-51-ethylenediaminetetraacetic a
We present a theoretical and experimental analysis of non Franck-Condon effects in photoionization to the b 4Σg- state of O2+. Experimentally, by dispersing the synchrotron radiation induced O2+ b 4Σg- - a 4Πu fluorescence we derive the b 4Σg- state vibrational branching ratios in the excitation energy range 21–34 eV. The vibrational branching ratios reveal features in the region 21–28 eV, indicat
The most frequently used model to describe the exponential increase in mortality rate over age is the Gompertz equation. Logarithmically transformed, the equation conforms to a straight line, of which the slope has been interpreted as the rate of senescence. Earlier, we proposed the derivative function of the Gompertz equation as a superior descriptor of senescence rate. Here, we tested both measu
Previous observational studies on the association between brachial blood pressure (BP) and cognition have reported conflicting results. Central BP has been hypothesized to be more strongly related to cognition than brachial BP. The aim of this study was to assess the association between brachial as well as central BP and cognitive function, both cross-sectionally and with brachial BP measured 17 y
Objectives. Studies reporting cancer risk after PMR and GCA are few, but it remains an issue of both concern and controversy. We examined the overall and specific cancer risks among Swedish subjects following hospitalization for these diseases. Methods. PMR and GCA patients were identified from the Swedish Hospital Discharge Register and by linking them with the Cancer Registry. Follow-up of patie
OBJECTIVE: Aortic aneurysm size is a critical determinant of the need for intervention, yet the maximal diameter will often vary depending on the modality and method of measurement. We aimed to define the relationship between commonly used computed tomography (CT) measurement techniques and those based on current reporting standards and to compare the values obtained with diameter measured using u
To evaluate the use of activated protein C-protein C inhibitor (APC-PCI) complex levels for detection of abdominal aortic aneurysm (AAA) in patients with peripheral atherosclerotic disease (PAD). APC-PCI levels and aortic diameter evaluated in 511 PAD patients without previously known AAA followed-up concerning survival for 4.8(0.5) years. AAA was found in 13 % of patients. Aortic diameter correla
Popular Abstract in Swedish Grundämnena tyngre än järns ursprung är en vital fråga inom historien on och evolutionen av vår galax. Grundämnena upp till och med järngruppen produceras huvudsakligen genom fusion inne i stjärnor som ger dem deras energi. De ännu tyngre grundämnena produceras istället huvudsakligen genom neutroninfångningsprocesser: Den svaga s-processen, huvud-s-processen och r-proce
We compared hippocampal volume measures obtained by manual tracing to automatic segmentation with FreeSurfer in 44 younger (20–30 years) and 47 older (60–70 years) adults, each measured with magnetic resonance imaging (MRI) over three successive time points, separated by four months. Retest correlations over time were very high for both manual and FreeSurfer segmentations. With FreeSurfer, correla
