Helicobacter pylori is a recognized causal factor of noncardia gastric cancer (GC). Lipopolysaccharide and peptidoglycan of this bacterium are recognized by CD14, TLR4 and NOD2 human proteins, while NFKB1 activates the transcription of pro-inflammatory cytokines to elicit an immune response. Single nucleotide polymorphisms (SNPs) in these genes have been associated with GC in different populations
The microphase structure of a series of polystyrene-b-polyethylene oxide-b-polystyrene (SEOS) triblock copolymers with different compositions and molecular weights has been studied by solid-state NMR, DSC, wide and small angle X-ray scattering (WAXS and SAXS). WAXS and DSC measurements were used to detect the presence of crystalline domains of polyethylene-oxide (PEO) blocks at room temperature as
Research in family medicine is a well-established entity nationally and internationally, covering all aspects of primary care including remote and isolated practices. However, due to limited capacity and resources in rural family medicine, its potential is not fully exploited yet. An idea to foster European rural primary care research by establishing a practice-based research network has been rece
An experimental study was conducted to investigate pressure drop and heat transfer in a U-bend section with various configurations of guide vanes and two kinds of rib shapes on the outer wall. Ten guide vane types were tested. Results highlight that the use of special guide vanes can reduce the pressure drop penalty up to a maximum of 31%. However, guide vanes are usually associated with heat tran
In persons with prior paralytic poliomyelitis, progressive muscle weakness can occur after a stable period of at least 15 years. Knowledge is limited about which factors influence changes in lower limb muscle strength in these persons. Objective. To assess changes in lower limb muscle strength annually over 4 years in persons with late effects of polio and to identify prognostic factors for change
There are various transport phenomena (gas-phase species, heat, and momentum) occurring at different length scales in anode-supported solid oxide fuel cells (SOFCs), which are strongly affected by catalytic surface reactions at active triple-phase boundaries (TPBs) between the void space (for gas), Ni (catalysts for electrons), and YSZ (an electrolyte material for ions). To understand the multisca
A sediment record from a small lake in the north-eastern part of the Kamchatka Peninsula has been investigated in a multi-proxy study to gain knowledge of Holocene climatic and environmental change. Pollen, diatoms, chironomids and selected geochemical parameters were analysed and the sediment record was dated with radiocarbon. The study shows Holocene changes in the terrestrial vegetation as well
OBJECTIVES: Decision on treatment of systemic sclerosis (SSc) related interstitial lung disease (ILD) largely relies on the findings on high resolution computed tomography (HRCT) and there is a need for improvement in assessment of the fibrotic activity. The objectives of this study were to study biomarkers in bronchoalveolar lavage fluid (BALF) from SSc patients with ILD and to relate the finding
A direct numerical simulation (DNS) coupling with multi-zone chemistry mapping (MZCM) is presented to simulate flame propagation and auto-ignition in premixed fuel/air mixtures. In the MZCM approach, the physical domain is mapped into a low-dimensional phase domain with a few thermodynamic variables as the independent variables. The approach is based on the fractional step method, in which the flo
Obesity is a global problem and in aspects of lethal ethanol intoxications virtually unexplored. The cause of death in ethanol intoxication is generally considered to be suppression of the respiratory function. Previous research indicates that respiratory function is more vulnerable in obese subjects than in those of normal weight. We hypothesized that lethal blood alcohol concentration (BAC) is l
Abstract in Undetermined Fospeg® is a newly developed photosensitizer formulation based on meso-tetra(hydroxyphenyl)chlorin (mTHPC), with hydrophilic liposomes to carry the hydrophobic photosensitizer to the target tissue. In this study the pharmacokinetics and biodistribution of Fospeg® were investigated by high performance liquid chromatography at various times (0.5-18 hours) following systemic
Background and purpose - Even small design modifications of uncemented hip stems may alter the postoperative 3-D migration pattern. The Furlong Active is an uncemented femoral stem which, in terms of design, is based on its precursor-the well-proven Furlong HAC-but has undergone several design changes. The collar has been removed on the Active stem along with the lateral fin; it is shorter and has
Little is known about the association between the metabolic syndrome (MetS) and the risk of gastric adenocarcinoma. The aim of this study was to investigate whether metabolic risk factors, together or combined, were associated with the risk of gastric adenocarcinoma. The Metabolic Syndrome and Cancer Project (Me-Can) is a pooling of prospective cohorts in Austria, Norway, and Sweden with informati
OBJECTIVE: Recordings of blood flow velocity waveform in the ductus venosus (DV) and the umbilical vein (UV) are routinely used in order to predict the fetal condition in high-risk pregnancies. This study investigates the relationship between pathological blood flow in the two vessels and perinatal outcome. METHODS: High-risk pregnancies (n=11865) admitted during 1993-2011 for blood flow examinati
Objectives To evaluate in a prospective, randomized clinical trial (RCT), symptom response among obese knee osteoarthritis (OA) patients following a feasible. intensive weight-loss program for 16 weeks Methods Eligible patients were obese [body mass index (BMI)> 30 kg/m(2)], >50 years old, with primary knee OA Participants were randomized to either a very-low-energy diet (VLED) or a low-energy die
AZD0837 is a novel oral anticoagulant investigated in clinical studies for stroke prevention in patients with atrial fibrillation (AF). It is bioconverted to its active form, AR-H067637, a potent, specific and reversible thrombin inhibitor.
Hypoxia is an important factor in the hematopoietic stem cell (HSC) niche in the bone marrow, but whether it also plays a role in the regulation of fetal liver (FL) HSCs is unclear. Vascular endothelial growth factor A (VEGFA) is essential for adult HSC survival, and hypoxic induction of VEGFA in adult HSCs is required for proper function. Loss of hypoxia-regulated VEGFA expression increases the n
Paja Brava is a native South American grass with a high carbohydrate content. In the current work, the potential of us- ing this feedstock for ethanol production using a simultaneous saccharification and fermentation (SSF) process with the xylose-fermenting yeast Pichia stipitis (Scheffersomyces stipitis) CBS6054 was investigated. The straw material was subjected to SO2 catalyzed steam pretreatmen
Chronic bronchitis and previous exacerbations are both well-known risk factors for new exacerbations, impaired health-related quality of life, and increased mortality in COPD. The aim of the study was to characterize the phenotype of concurrent chronic bronchitis and frequent exacerbation in severe COPD.
The cyclooxygenase (COX) pathway and prostanoids may critically contribute to the early allergic airway response. In the rat lung, serotonin (5-HT) is a major mediator of antigen-induced contractions. The aim of this study was therefore to examine the relative role of the COX pathway and serotonin for antigen-induced contractions in the rat lung. Airway responses were studied in rat precision-cut
