Opis:
The current limitations of surgical treatment, as well as restrictions on professional and sport activities related to COVID-19 pandemic require seeking therapeutic solutions for the vast population of patients with chronic venous insufficiency (CVI, chronic venous insufficiency). To understand the principles of pharmacotherapy of this disease, the authors used data related to epidemiology and pathophysiology of CVI. They provided the latest data on venoactive drugs and recommendations that should be followed and summarized the literature based on the EBM. The article should provide the answer to the question of how to deal with patients with varicose veins or, more broadly, chronic venous insufficiency during the pandemic.

Opis:
High current linear discharges confined by their own magnetic field are subject to magneto-hydrodynamic instabilities which perturb a straight plasma column. An example is the m=0 mode, which is characterised by the development of necks contracting rapidly towards the axis with the ion sound speed. Discharges through capillaries were assumed to be stable hitherto, but by cutting capillaries lengthwise after a few shots hot spot traces clearly imprinted on the inner wall of the capillary are observed. They are interpreted as marks of an m=0 instability, and this interpretation is substantiated by a series of time-gated pinhole images, which show that the hot plasma region is clearly detached from the wall at the second current maximum and concentrated on the axis thus making the development of the instability possible. The instability occurs only with a specific sample of polyacetal as wall material, and its axial wavelength increases with the length of the capillary. By modulating respectively the inner wall of the capillary the wavelength can be imposed within limits. This is exploited for a soft X-ray laser scheme based on charge exchange pumping of bare carbon ions of hot plasma streaming from the necks and colliding with cold plasma outside the neck regions. Exponential growth of the Balmer-alfa line of CVI at 18.22 nm is realised.
