Electrotransport Properties of Perfluorinated Cation-Exchange Membranes of Various Thickness.

The present work discusses the influence of the thickness of MF-4SK perfluorinated sulfonic cation-exchange membranes on their electrotransport properties in hydrochloric acid solutions. It is found that diffusion permeability and conductivity are primarily determined with the specific water content of the membranes and increase with their increase. Analysis of the contribution of reverse diffusion through the membrane to the value of the limiting current shows that it can reach 20% for membranes with a thickness of 60 μm.

[The effect of low-frequency electrostatic therapy on immunoinflammatory reactions in patients with acute myocardial infarction after endovascular myocardial revascularization at the inpatient stage of medical rehabilitation].

Purpose Of The Study: To study the effect of complex rehabilitation with the inclusion of low-frequency electrostatic therapy on the dynamics of immune status in patients with myocardial infarction (MI) after endovascular myocardial revascularization.

Material And Methods: The state of the immune status was studied in 68 patients with MI after percutaneous coronary intervention (PCI) - coronary angioplasty with stenting, admitted to the inpatient stage of medical rehabilitation.

Results: The study proved the involvement of the immune system in a complex set of reactions occurring in patients with myocardial infarction after PCI.

[On the assessment of medical rehabilitation effectiveness in patients with chronic obstructive pulmonary disease in the resort setting].

Unlabelled: Despite significant successes of health resort rehabilitation in patients with chronic obstructive pulmonary disease (COPD), the assessment of rehabilitation effectiveness remains challenging for resort physicians in Russia.

Objective: To perform a comparative analysis of methods for assessing the medical rehabilitation outcomes in COPD patients in the resort setting.

Material And Methods: The study involved 71 patients with stage I-II COPD, with bronchitis (66.

[Comprehensive medical rehabilitation using therapeutic physical factors including hydrokinesiotherapy in a pool with mineral water and its effect on circadian rhythms of arterial pressure and autonomic regulation in patients with arterial hypertension and with chronic psychoemotional stress].

Objective: To study the effect of the course-based comprehensive rehabilitation using the therapeutic physical factors of the Belokurikha resort, including hydrokinesiotherapy in a pool with mineral water on the circadian rhythms of arterial pressure and its autonomous regulation in patients with arterial hypertension (AH) associated with chronic psychoemotional stress (CPES).

Material And Methods: The study involved 83 patients with stage I-II grade 1-2 of AH, whose professional activities were associated with CPES. Each participant had 24-hours Holter blood pressure monitored, and cardiointervalography (CIG) was performed before and after the medical rehabilitation course.

Permselectivity of Cation Exchange Membranes Modified by Polyaniline.

This work discusses the applicability of polyaniline-modified cation exchange membranes for the separation of monovalent/divalent cations by electrodialysis. A novel method of membrane modification directly in the electrodialysis unit is used to prepare permselective membranes. Complex characterization of the membranes before and after modification allows revealing the influence of membrane matrix on the modification efficiency.
