Бокс в Томском Политехническом университете

Это первая книга о боксе в одном из томских университетов. События, факты, рассказы о боксёрах и их тренерах основаны на документальных материалах, в том числе из архивных источников, воспоминаниях ветеранов и действующих спортсменов. Это знак благодарности и признания боксёрам, тренерам и спортивным организаторам за их нелёгкую, но благодарную работу, за популяризацию бокса. В результате работы получилась содержательная и увлекательная книга, которая вызовет несомненный интерес у читателей, и будет способствовать популяризации такого замечательного вида единоборств как бокс

Knee arthroscopy and exercise versus exercise only for chronic patellofemoral pain syndrome: a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Arthroscopy is often used to treat patients with chronic patellofemoral pain syndrome (PFPS). As there is a lack of evidence, we conducted a randomized controlled trial to study the efficacy of arthroscopy in patients with chronic PFPS.</p> <p>Methods</p> <p>A total of 56 patients with chronic PFPS were randomized into two treatment groups: an <it>arthroscopy group </it>(<it>N </it>= 28), treated with knee arthroscopy and an 8-week home exercise program, and a <it>control group </it>(<it>N </it>= 28), treated with the 8-week home exercise program only. The arthroscopy included finding-specific surgical procedures according to current recommendations. The primary outcome was the Kujala score on patellofemoral pain and function at 9 months following randomization. Secondary outcomes were visual analog scales (VASs) to assess activity-related symptoms. We also estimated the direct healthcare costs.</p> <p>Results</p> <p>Both groups showed marked improvement during the follow-up. The mean improvement in the Kujala score was 12.9 (95% confidence interval (CI) 8.2–17.6) in the arthroscopy group and 11.4 (95% CI 6.9–15.8) in the control group. However, there was no difference between the groups in mean improvement in the Kujala score (group difference 1.1 (95% CI -7.4 - 5.2)) or in any of the VAS scores. Total direct healthcare costs in the arthroscopy group were estimated to exceed on average those of the control group by €901 per patient (<it>p </it>< 0.001).</p> <p>Conclusion</p> <p>In this controlled trial involving patients with chronic PFPS, the outcome when arthroscopy was used in addition to a home exercise program was no better than when the home exercise program was used alone.</p> <p>Trial registration</p> <p>Current Controlled Trials ISRCTN 41800323</p

Breast cancer biological subtypes and protein expression predict for the preferential distant metastasis sites: a nationwide cohort study

Introduction Some molecular subtypes of breast cancer have preferential sites of distant relapse. The protein expression pattern of the primary tumor may influence the first distant metastasis site. Methods We identified from the files of the Finnish Cancer Registry patients diagnosed with breast cancer in five geographical regions Finland in 1991-1992, reviewed the hospital case records, and collected primary tumor tissue. Out of the 2,032 cases identified, 234 developed distant metastases after a median follow-up time of 2.7 years and had the first metastatic site documented (a total of 321 sites). Primary tumor microarray (TMA) cores were analyzed for 17 proteins using immunohistochemistry and for erbB2 using chromogenic in situ hybridization, and their associations with the first metastasis site were examined. The cancers were classified into luminal A, luminal B, HER2+ enriched, basal-like or non-expressor subtypes. Results A total of 3,886 TMA cores were analyzed. Luminal A cancers had a propensity to give rise first to bone metastases, HER2-enriched cancers to liver and lung metastases, and basal type cancers to liver and brain metastases. Primary tumors that gave first rise to bone metastases expressed frequently estrogen receptor (ER) and SNAI1 (SNAIL) and rarely COX2 and HER2, tumors with first metastases in the liver expressed infrequently SNAI1, those with lung metastases expressed frequently the epidermal growth factor receptor (EGFR), cytokeratin-5 (CK5) and HER2, and infrequently progesterone receptor (PgR), tumors with early skin metastases expressed infrequently E-cadherin, and breast tumors with first metastases in the brain expressed nestin, prominin-1 and CK5 and infrequently ER and PgR. Conclusions Breast tumor biological subtypes have a tendency to give rise to first distant metastases at certain body sites. Several primary tumor proteins were associated with homing of breast cancer cells.BioMed Central Open acces

The immune system and the impact of zinc during aging

The trace element zinc is essential for the immune system, and zinc deficiency affects multiple aspects of innate and adaptive immunity. There are remarkable parallels in the immunological changes during aging and zinc deficiency, including a reduction in the activity of the thymus and thymic hormones, a shift of the T helper cell balance toward T helper type 2 cells, decreased response to vaccination, and impaired functions of innate immune cells. Many studies confirm a decline of zinc levels with age. Most of these studies do not classify the majority of elderly as zinc deficient, but even marginal zinc deprivation can affect immune function. Consequently, oral zinc supplementation demonstrates the potential to improve immunity and efficiently downregulates chronic inflammatory responses in the elderly. These data indicate that a wide prevalence of marginal zinc deficiency in elderly people may contribute to immunosenescence

Laminin production by murine melanoma cells: possible involvement in cell motility

Three lines of B16 melanoma cells (B16-F1, B16-F10 and B16-BL6) were examined for motility in the micropore filter assay and for synthesis in culture of the basal lamina glycoprotein laminin. All three lines synthesized laminin as judged by the incorporation of [ 35 S]methionine into immunoreactive laminin and secreted (or shed) laminin into the culture medium as indicated by biosynthetic labeling studies and enzyme-linked immunosorbent assays. Immunoreactive laminin was also seen on the surface of the cells as indicated by immunofluorescence staining and by complement-mediated killing. Analysis of [ 35 S]methionine-labeled laminin immunoprecipitates by sodium dodecylsulfatepolyacrylamide gel electrophoresis (SDS-PAGE) both with and without reduction of intersubunit disulfide bonds revealed that all three cell lines produced a similar array of laminin forms, and that the M r =950kD laminin molecule (but not the uncombined subunits) was secreted into the culture medium. Laminin biosynthesis appeared to be limited by the availability of the M r =400kD A subunit as shown by the intracellular accumulation of excess B subunit in the form of uncombined B subunit ( M r =200kD) and as a disulfide-linked B dimer ( M r =400 kD). The motility of all three cell lines was stimulated four- to five-fold by the addition of either exogenous laminin from the EHS sarcoma or culture medium from the B16 cells containing the secreted laminin. The stimulated motility was inhibited by antilaminin serum. These observations suggest that the laminin synthesized by the B16 melanoma cells themselves may facilitate their motility.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42594/1/10585_2004_Article_BF00133591.pd
