Epidermolysis Bullosa (EB) is a group of rare genetic skin conditions, which is characterised by extremely fragile skin and recurrent blister formation, resulting from minor mechanical friction or trauma. Sufferers of EB have compared the sores to third-degree burns. Stevens-Johnson syndrome is a rare but very serious skin problem, which causes the appearance of reddish lesions throughout the body and other changes, such as difficulty in breathing and fever, which can endanger the life of the affected person. The aim of this study was to show efficacy of a NANOSKIN ACT, AND NANOSKIN ACT SOFT wound dressing on the wound care management in patients with EB AND Stevens-Johnson syndrome (SJS).

For the first time it is shown that psychotropic action of acetylsalicylates at various doses is manifested as a nonmonotonic dependence having its peaks at therapeutic and ultra-low dose zones. It is discovered that development of effects of aspirin resembles that of acetylsalicylate zinc. Acetylsalicylate cobalt at extremely low doses zone showed the highest antidepressant activity, demonstrating toxicity at high doses. Generally, it is revealed that the use of aspirin and its salts at high doses range causes maximum psychotropic effects development, usually accompanied by side-effects. Therefore, aspirin, acetylsalicylate cobalt and zinc at extremely low doses are recommended for further study as psychotropic medications.

Evolution of periodic orbits in Sun-Mars and Sun-Earth systems are analyzed using Poincare surface of section technique and the effects of solar radiation pressure of bigger primary and actual oblateness of smaller primary on these orbits areconsidered. It is observed that solar radiation pressure of bigger primary has substantial effect on period, orbit’s shape, size and their position in the phase space. Since these orbits can be used for the design of low energy transfer trajectories, so perturbations due to solar radiation pressure has to be understood and should be taken care of during trajectory design. It is also verified that stability of such orbits are negligible so they can be used as transfer orbit. For each pair of solar radiation pressure q and Jacobi constant C we get two separatrices where stability of island becomes zero. In this paper, detailed stability analysis of periodic orbit having two loops is given when q = 0.9845.

The effect of repetitive pulsed microwaves （10 GHz, pulse duration of 100-300 ns, pulse repetition rate of 4-25 pulse per second, peak power density of 0.04-3.5 kW/cm^2） on mastocytoma P815, Ehrlich carcinoma, normal spleen cells and wound healing was investigated. It was found that short-time irradiation with an intensity of 0.9-1.5 kW/cm^2 inhibited proliferation of tumor cells in vitro, whereas at same time it contributes to proliferation of normal spleen cells in vitro. The repetitive pulsed microwaves with an intensity of 0.04-1.5 kW/cm^2 stimulated healing of skin wounds and ulcerations in mice. The effects showed a dependence on the pulse repetition rate and irradiation intensity.
