Interaction of mono- and disaccharides, polysaccharide particles and yeast cells with boronate-containing copolymers (BCC) of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with NN-dimethylacrylamide (DMAA) or N-isopropylacrylamide (NIPAM) was studied. The binding of saccharides to BCC of NIPAM resulted in a shift of its phase transition temperature (Delta T-p), which provided a quantitative measur

Disturbances in intestinal metabolism and perfusion during SIRS can be direct effects of toxic substances, and/or effects secondary to hypovolemia. An attempt to evaluate the significance of hypovolemia for intestinal disturbances during SIRS was made in the present study on feline by evaluating the degree to which the intestinal alterations following endotoxin infusion were restored by a clinical

To construct the recombinant adenovirus vector containing the cDNA for recombinant mouse cyclic nucleotide phosphodiesterase 3B (mPDE3B), the cDNA for mPDE3B was subcloned into pACCMV.pLpA. Subsequently, this recombinant plasmid, pACCMV.mPDE3B, was cotransfected with pJM17 plasmid containing the adenoviral genome into 293 human embryonic kidney cells, and the replication-deficient adenovirus AdCMV

Background The contribution of genetic variation in DNA repair genes to gastric cancer (GC) risk remains essentially unknown. The aim of this study was to explore the relative contribution of DNA repair gene polymorphisms to GC risk and severe chronic atrophic gastritis (SCAG). Method A nested case control study within the EPIC cohort was performed including 246 gastric adenocarcinomas and 1175 ma

The influence of major surgery on HIV disease progression and decline in CD4+ cell count was evaluated in 23 seropositive haemophilia patients. 24 HIV-infected patients served as non-operated controls. In addition, 32 age-matched seronegative subjects were included. The follow-up time was up to 5 years. During the course of the study, eight of the operated (35%) and 11 of the non-operated (48%) su

We examined correlates of antinuclear antibody (ANA) positivity (ANA+) in individuals with chronic hepatitis C virus (HCV) infection and the effect of positivity on clinical outcome of HCV. Pretreatment sera from 645 patients from three centres in Sweden (n = 225), the UK (n = 207) and Italy (n = 213) were evaluated by indirect immunofluorescence on Hep-2 cells for ANA pattern and titre by a singl

Helicobacter pylori infection is a causal factor of gastric cancer (which is associated with low gastric acid secretion) or duodenal ulcer (high acid secretion). Parietal cells and ECL cells in the stomach are controlled by gastrin, which plays a crucial role in the regulation of acid secretion. The present study was undertaken to identify a possible role of gastrin in determining the different re

The acidic proteome of Lactococcus lactis grown anaerobically was compared for three different growth conditions: cells growing on maltose, resting cells metabolizing maltose, and cells growing on glucose. In maltose metabolizing cells several proteins were up-regulated compared with glucose metabolizing cells, however only some of the up-regulated proteins had apparent relation to maltose metabol

Information on objectively assessed physical activity in elderly people is scarce. The aim of this study was to investigate accelerometer measures in elderly women, and its relation to other indices of physical activity and bone density. A subset of 57 women, all 80 years old, (range 80.0-80.7) of the Malmo OPRA study was equipped with an MTI accelerometer for a period of 5-7 days. A 7-day activit

Cardiac index, systemic and pulmonary arterial pressures, carbon dioxide elimination and ventilation of each lung were studied during thoracotomy. Seventeen patients, placed in the full lateral position, were ventilated mechanically through a Carlens' tube to moderate hypocapnia. Mean cardiac index increased by 12% as the pleura was opened (P less than 0.05), with no further change during surgery

Background: Despite uniform operating techniques, lack of fusion still occurs after ankle arthrodesis. Differences in the biological healing potential may be a factor but the mechanical performance of the arthrodesis construct because of varying bone quality also may be important. Internal compression techniques are preferred because of higher union rates, shorter fusion times, and fewer complicat

Objective: To analyse the effects of socioeconomic disadvantage on access to dental care services and on oral health. Design, setting and outcomes: Cross-sectional data from the Swedish National Surveys of Public Health 2004 and 2005. Outcomes were poor oral health (self-rated oral health and symptoms of periodontal disease) and lack of access to dental care services. A socioeconomic disadvantage

We have previously described the efficient guidance and unidirectional sliding of actin filaments along nanosized tracks with adsorbed heavy meromyosin (HMM; myosin II motor fragment). In those experiments, the tracks were functionalized with trimethylchlorosilane (TMCS) by chemical vapor deposition (CVD) and surrounded by hydrophilic areas. Here we first show, using in vitro motility assays on no

Proteinase 3 (PR3) is a neutrophil serine protease stored in the azurophil granules of the promyelocyte and its successors. The protease has been identified as an autoantigen for anti-neutrophil cytoplasmic autoantibodies (ANCA) occurring in patients with Wegener's granulomatosis. To characterize the biosynthesis and processing of human PR3 in a transgenic cellular model, cDNA encoding human pre-p

The aim of this research was to analyze the effects and the modes of action of elemental sulfur (So) in bioluminescence and respiration of Vibrio fischeri cells and the enzymes crude luciferase, pure catalase, and alcohol dehydrogenase (ADH). Metallic copper removed sulfur and reduced the toxicity of acetone extracts of sediment samples analyzed in the bioluminescence test. The sulfur inhibition o

Objective: To evaluate if the calcium channel blocker diltiazem protects postoperatively renal function in cardiac surgical patients with preexisting mild-to-moderate renal dysfunction. Design: Prospective, randomized, placebo-controlled, double-blind, clinical study. Setting: Cardiothoracic anesthesia department at a university hospital. Participants: Adult patients undergoing elective cardiac su

Most, but not all, studies have found that women with a high urinary 2-hydroxyestrogen (2OHE) to 16 alpha-hydroxyestrone (16 alpha OHE1) ratio are at reduced risk for breast cancer and have a better prognosis. The aim was to identify factors associated with the pre-operative 2OHE to 16 alpha OHE1 ratio and factors that predicted the change in the ratio between the pre-operative visit and first fol

Nearly all mammalian cells express a set of genes known as clock genes. These regulate the circadian rhythm of cellular processes by means of negative and positive autoregulatory feedback loops of transcription and translation. Recent genomewide association studies have demonstrated an association between a polymorphism near the circadian clock gene CRY2 and elevated fasting glucose. To determine
