Phage solutions, host growth and phage infection were tested in different temperatures revealing phage temperature tolerance up to 45 A degrees C, whereas phage infection was in most of the cases retarded above 15 A degrees C. This study is the first to report isolation and cultivation of ice bacteria and cold-active phages from the Baltic Sea ice.”
“The purpose of this study was to evaluate the age-related
changes in anaerobic power in the former highly trained oarsmen and kayakers, i.e. the representatives of sports requiring high endurance capacity and strength. Sixty-six former athletes, aged find more 30-67 years participated in this study. The subjects were assessed for peak anaerobic power in arms (P(an) (arms)) and legs (P(an) (legs)) during 10 s-maximal cycle ergometer exercise tests and for peak aerobic power (P(VO2max)) during incremental
exercise. Body mass, lean body mass and body fat content were measured as well. The peak anaerobic power decline in the former highly trained athletes examined in the present study equalled to 0.6-0.7% per year. The recreational physical activity, based primarily on the endurance exercises, did not affect the peak anaerobic power whereas the peak aerobic power and body fat content strongly depended on the age and physical activity. The peak anaerobic power in the upper and lower extremities exhibited similar reduction with age of the subjects. selleck inhibitor Furthermore, in the less active group the ratio of P(an legs) to P(VO2max) did not change with age whereas in physically see more active subjects this index increased. It was concluded that in the sample of former highly trained oarsmen and kayakers the age-related decline in the peak anaerobic power approximated that reported by other authors for untrained or endurance trained subjects, the peak anaerobic power in the arms was almost the same as that in
the legs and that in the less active group the ratio of the peak anaerobic power to the peak aerobic power was independent of age and strongly tended to increase in the physically active subjects.”
“Inflammatory bowel disease (IBD) is an autoimmune disease characterized by a chronic inflammation of the gastrointestinal tract mucosa and is related to an abnormal immune response to commensal bacteria. Our aim of the present work has been to explore the levels of antibodies (IgG and IgA) raised against extracellular proteins produced by LAB and its association with IBD. We analyzed, by Western-blot and ELISA, the presence of serum antibodies (IgA and IgG) developed against extracellular protein fractions produced by different food bacteria from the genera Bifidobacterium and Lactobacillus. We used a sera collection consisting of healthy individuals (HC, n = 50), Crohn’s disease patients (CD, n = 37), and ulcerative colitis patients (UC, n = 15). Levels of IgA antibodies developed against a cell-wall hydrolase from Lactobacillus casei subsp.
