Opis:
Many hikers, mountaineers and climbers use telescopic sticks because they may aid walking up/downhill and may also ease the strain on the spine and the lower extremity joints particularly the knees. The reductions during downhill walking with hiking poles are caused primarily by the forces applied to the hiking poles and by a change in posture to a more forward leaning position of the upper body.In order to have any benefits from telescopic sticks, they must be used with the correct technique: The sticks must be height-adjustable and have handles that are constructed in a way that the user’s hands, when pressing down, firm support is provided (or gained). It is of utmost importance to use the sticks as close as possible to the body’s line of fall. It has been shown that there is no significant difference in using one or two sticks when walking without a load, but when walking with a load, balance is significantly enhanced by using two hiking sticks rather than one. Previously a possible loss of the ability to maintain balance in rough or exposed terrain (e.g. small ridges) has been discussed (Berghold, F. personal communication). However, this could not be supported by studies. At high altitude or in cold environment the sticks should not be adjusted too long (the hands should be lower than the elbow when using the stick), because otherwise the circulation will be impaired and the user will get cold fingers in a very short time.

Opis:
In both forms of muscular dystrophy, the severe Duchenne’s muscular dystrophy (DMD) with lifespan shortened to about 20 years and the milder Becker dystrophy (BDM) with normal lifespan, the gene defect is located at chromosome locus Xp21. The location is the same in the experimental model of DMD in the mdx mice. As the result of the gene defect a protein called dystrophin is either not synthesized, or is produced in traces. Although the structure of this protein is rather well established there are still many controversies about the dystrophin function. The most accepted suggestion supposes that it stabilizes sarcolemma in the course of the contraction-relaxation cycle. Solving the problem of dystrophin function is a prerequisite for introduction of an effective therapy. Among the different factors which might be responsible for the appearance and progress of dystrophic changes in muscles there is an excessive action of oxidative stress. In this review data indicating the influence of oxidative stress on the severity of the pathologic processes in dystrophy are discussed. Several pieces of data indicating the action of oxidative damage to different macromolecules in DMD/BDM are presented. Special attention is devoted to the degree of oxidative damage to muscle proteins, the activity of neuronal nitric oxide synthase (nNOS) and their involvement in defining the severity of the dystrophic processes. It is indicated that the severity of the morbid process is related to the degree of oxidative damage to muscle proteins and the decrease of the nNOS activity in muscles. Estimation of the degree of the destructive action of oxidative stress in muscular dystrophy may be a useful marker facilitating introduction of an effective antioxidant therapy and regulation of nNOS activity.
