Background: Prostate cancer screening depends on a careful balance of benefits, in terms of reduced prostate cancer mortality, and harms, in terms of overdiagnosis and overtreatment. We aimed to estimate the effect on overdiagnosis of restricting prostate specific antigen (PSA) testing by age and baseline PSA. Methods: Estimates of the effects of age on overdiagnosis were based on population based
BACKGROUND:The incidence of invasive disease caused by encapsulated Haemophilus influenzae type f (Hif) has increased in the post-H. influenzae type b (Hib) vaccine era. We previously annotated the first complete Hif genome from a clinical isolate (KR494) that caused septic shock and necrotizing myositis. Here, the full genome of Hif KR494 was compared to sequenced reference strains Hib 10810, cap
Scatter correction in SPECT is important for improving image quality, boundary detection and the quantification of activity in different regions. This paper presents a comparison of four scatter correction methods, three using more than one energy window and one convolution-subtraction correction method using spatial variant scatter line-spread functions. METHODS: The comparison is based on Monte
Purpose: The purpose of this clinical investigation was to evaluate the treatment outcome with zygoma implants with regard to implant survival, patient satisfaction, and function of prosthesis replacement after 3 years. Patients and Methods: The treatment outcome of 76 patients treated with 145 zygoma fixtures at 16 centers was evaluated with regard to implant survival. Status of peri-implant muco
The Autocapture algorithm enables automatic capture verification on a beat-by-beat basis by recognizing the evoked response signal following each pacemaker stimulus. The algorithm intends to increase patient safety while decreasing energy consumption. However, the occurrence of fusion beats, particularly during dual chamber pacing, may limit the energy saving effect of Autocapture. The aim of this
Sequence-dependent coordination of alkali ions to the nucleotide bases in the minor groove of AT-tract B-DNA has recently been inferred from X-ray crystallography, solution NMR and computer simulations. Here, we present new Na-23 and Rb-87 magnetic relaxation dispersion (MRD) data that demonstrate competitive and long-lived binding of Na+ and Rb+ ions in the minor groove of the B-DNA duplex [d(CGC
Denna bok handlar om de franska S:t josefsystrarna och deras missionsverksamhet i Skandinavien från mitten av 1800-talet och fram till 1950-talet med fokus på deras skol- och sjukvårdsverksamhet samt den specifika kvinnokultur som de representerade. Female Counter-Culture and Catholic Mission. The St Joseph Sisters in Denmark and Sweden 1856-1936 In May 1856, four Catholic sisters arrived in Denmark and established a community in a small basement of a building close to the Catholic parish church in Copenhagen. These Catholic sisters belonged to a French religious congregation named "La Congregation des Sœurs de Saint-Joseph de Chambéry", whi
The power expenditure of flapping flight in birds is characterised by a U-shaped function of speed through the air. From this relationship and the assumption of limited power available from flight muscles, it is possible to predict changes in the birds' airspeed in relation to external factors such as wind. These predictions are derived from flight mechanical theory and optimality criteria concern
Macroarray analysis was used to compare equal amounts of cDNA from wild-type and rd/rd (retinal degeneration) mice, collected at P90 when photoreceptor degeneration is virtually complete. A stronger signal for the glycolytic enzyme phosphoglucose isomerase (Gpi1) was observed in the rd/rd sample. Extracellularly, Gpi1 may act as a cytokine, independently described as neuroleukin and autocrine moti
In bacterial meningitis, chemokines lead to recruitment of polymorphonuclear leucocytes (PMN) into the CNS. At the site of infection in the subarachnoid space, PMN release reactive oxygen species, reactive nitrogen intermediates (RNI) and interleukin-1 beta (IL-1 beta). Although these immune factors assist in clearance of bacteria, they also result in neuronal injury associated with meningitis. Tr
Components that propagate inflammation in joint disease may be derived from cartilage since the inflammation resolves after joint replacement. We found that the cartilage component fibromodulin has the ability to activate an inflammatory cascade, i.e. complement. Fibromodulin and immunoglobulins cause comparable deposition of C1q, C4b, and C3b from human serum. Using C1q and factor B-deficient ser
Orientation experiments were performed with first-year snow buntings (Plectrophenax nivalis) during their autumn migration in a natural near-vertical geomagnetic field approximately 400 km away from the magnetic north pole. Migratory orientation of snow buntings was recorded using two different techniques: orientation cage tests and freeflight release experiments. Experiments were performed under
It is considered that fruit and vegetable (F&V) protect against oesophagus and gastric cancer (GC). However, 2 recent meta-analyses suggest that the strength of association on GC seems to he weaker for vegetables than for fruit and weaker in cohort than in case-control studies. No evidence exists from cohort studies about adenocarcinoma of oesophagus (ACO). In 521,457 men and women participati
BACKGROUND & AIMS: Our aims were to develop a method to accurately predict non-alcoholic fatty liver disease (NAFLD) and liver fat content based on routinely available clinical and laboratory data and to test whether knowledge of the recently discovered genetic variant in the PNPLA3 gene (rs738409) increases accuracy of the prediction. METHODS: Liver fat content was measured using proton magne
Popular Abstract in English An endospore, which can be formed by some bacteria, is a dormant and extremely endurable state which helps the cell to survive long periods of harsh environmental conditions. The penicillin-binding protein SpoVD in Bacillus subtilis is essential for the synthesis of the endospore cortex, a protective layer consisting of modified peptidoglycan. In depth investigation of Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. This layer is required for heat resistance of the spore and mutant spores lacking the cortex layer can be identified by a simple heat shock assay. B. su
The use of fluorescence and reflectance spectroscopy in the analysis of cervical histopathology is a growing field of research. The majority of this research is performed with point-like probes. Typically, clinicians select probe sites visually, collecting a handful of spectral samples. An exception to this methodology is the Hyperspectral Diagnostic Imaging (HSDI®) instrument developed by Science
Popular Abstract in Swedish Malign hypertermi, ärftligt och farligt vid narkos – hur diagnostiseras det ? I april 1960 sövdes en yngling i Australien. Han var mycket orolig därför att tio släktingar dött av eter-narkos. Han sövdes i stället med ett nytt medel – halotan, det höll på att kosta även honom livet. En kortfattad fallbeskrivning i Lancet fick stor uppmärksamhet och på andra ställen i väMalignant hyperthermia (MH) susceptibility is a rare inherited muscular disorder, which may cause a lethal increase in metabolism during anaesthesia with certain commonly used anaesthetic. Susceptible individuals are without any signs or symptoms. It is important to identify individuals at risk, since the MH reaction is preventable. Susceptibility to MH is diagnosed with an in vitro contracture te
Interactions of adenosine 3':5'-cyclic monophosphate (cAMP) and N-6,2'-O-dibutyryl-adenosine 3':5'-cyclic monophosphate (dbcAMP) with a lipid layer composed of monoolein-based preparation and dioleoyl phosphatidylcholine ( DOPC) were investigated by small-angle X-ray diffraction (SAXD) and Raman spectroscopy. The reversed hexagonal (H-II) MO/DOPC/H2O phase of 65:15:20 wt.% composition was selected
