The concept of kinematic chains has been systematically applied to biological systems since the 1950s. The course of a ski jump can be characterized as a change between closed and open kinematic chains. The purpose of this study was to determine a relationship between adjacent segments within the ski jumper's body's kinematic chain during the in-run phase of the ski jump. The in-run positions o...
BACKGROUND There is limited knowledge about key injury risk factors in alpine ski racing, particularly for World Cup (WC) athletes. OBJECTIVE This study was undertaken to compile and explore perceived intrinsic and extrinsic risk factors for severe injuries in WC alpine ski racing. METHODS Qualitative study. Interviews were conducted with 61 expert stakeholders of the WC ski racing communit...
this study examined the relationship between tourists' motivations and satisfaction in tehran ski resorts. the study was a descriptive study and of correlation kind and conducted as a field study. the statistical population consisted of all tourists of tehran ski resorts (dizin, shemshak, tochal and abali). according to the estimates of the managers of these ski resorts, the statistical po...
Cisplatin is frequently used in treating gastric cancers; however, acquired resistance to the drug often reduces the efficacy of therapy. The present study analyzed the efficacy of the combination of 4-[4-(4-chloro-phenyl)-thiazol-2-ylamino]-phenol (SKI-II) and cisplatin [cis-diamminedichloroplatinum (II); DDP] on the gastric cancer SGC7901/DDP cell line. The results revealed that SKI-II and DD...
Src family kinase activity is elevated in many human tumors, including breast cancer, and is often associated with aggressive disease. We examined the effects of SKI-606 (bosutinib), a selective Src family kinase inhibitor, on human cancer cells derived from breast cancer patients to assess its potential for breast cancer treatment. Our results show that SKI-606 caused a decrease in cell motili...
BACKGROUND Ski waxes are applied onto the skis to improve the performance. They contain different chemical substances, e.g. perfluoro-n-alkanes. Due to evaporation and sublimation processes as well as mechanically generated dust, vapours, fumes, and particulates can contaminate the workroom atmosphere. The number of professional ski waxers is increasing, but occupational exposure assessments am...
Triptolide as a main active ingredient of Tripterygium wilfordii is known to be exerting anti-inflammatory, marked immunosuppressive, and podocyte-protective effects. In this study, we investigated the protective effect of triptolide in kidney disease. Rat glomerular mesangial cells were randomly divided into three groups: (1) control group, (2) TGF-β1 (10 μg/mL) group, and (3) triptolide group...
The c-ski locus extends a minimum of 65 kb in the chicken genome and is expressed as multiple mRNAs resulting from alternative exon usage. Four exons comprising approximately 1.5 kb of cDNA sequence have been mapped within the chicken c-ski locus. However, c-ski cDNAs include almost 3 kb of sequence for which the exon structure was not defined. From our studies using the polymerase chain reacti...
We recently demonstrated that Ski is a novel wound healing-related factor that promotes fibroblast proliferation and inhibits collagen secretion. Here, we show that increasing local Ski expression by gene transfer not only significantly accelerated wound healing by relieving inflammation, accelerating re-epithelialization and increasing formation of granulation tissue, but also reduced scar for...
INTRODUCTION Spinal protective devices are a recent addition to the protective equipment worn by competitive and recreational alpine skiers and snowboarders. Their rate of use is not documented at the time of publication. The objective of this study was to examine the current attitudes and recommendations of Canadian alpine ski racing coaches towards spinal protective devices. METHODS A conve...
