Decontamination efficacy of sodium hypochlorite solutions for poliovirus.

Effective decontamination procedures are critical to the successful manufacture and control of poliovirus vaccines to minimize the risk to personnel and the environment. Polio viruses have been reported to be more resistant to disinfectants than many other viruses. We assessed the efficacy of sodium hypochlorite-containing disinfectants for decontamination for three poliovirus serotypes to implement decontamination procedures that are fully compliant with the WHO GAP III and Health authorities' requirements.

Interaction force between two finite-size charged particles in weakly ionized plasma.

The results of numerical studies of the interaction forces between two finite-size charged spherical conductive particles embedded into weakly ionized strongly collisional isothermal plasma-like medium are presented. The studies are performed for the case of particles with fixed electric charge under the assumption that particles do not absorb electrons and ions from the surrounding plasma (colloidal particles) as well as for particles charged by plasma currents (grains). In the first case the Poisson-Boltzmann model was used and in the second the dynamics of grain charging is described in the drift-diffusion approximation.

[Acute mesenteric ischemia complicated by intestinal necrosis: choice of strategies of treatment].

Treatment of intestinal necrosis, caused by an acute mesenterial ischemia, represents the most complex field of surgery. Results of surgical treatment of 74 patients with various forms of mesenterial ischemia, complicated by intestinal infarction, were analyzed. Revascularization ought to be conducted if the ischemia may be eliminated.

Is a one-week course of triple anti-Helicobacter pylori therapy sufficient to control active duodenal ulcer?

Background: Triple therapy currently forms the cornerstone of the treatment of patients with Helicobacter pylori-positive duodenal ulcer.

Aim: To establish whether prolonged antisecretory therapy is necessary in patients with active duodenal ulcer.

Methods: A total of 77 patients with H.
