[Progressive multifocal leukoencephalopathy in HIV-positive individuals].

The article discusses the historical aspect and modern ideas about the etiology and pathogenesis of progressive multifocal leukoencephalopathy in patients with HIV infection. An analysis and synthesis of literature data on the clinical presentation of this pathology was carried out. The possibilities and limitations of laboratory and instrumental diagnostic methods, including neuroimaging methods, are discussed in detail.

Daily Duration of Compression Treatment in Chronic Venous Disease Patients: A Systematic Review.

There are no data on the daily regimen of compression therapy in patients with chronic venous disease. This systematic review aimed to establish the optimal daily duration of compression treatment. A systematic search of CENTRAL and MEDLINE was performed to identify RCTs, non-RCTs, reviews, systematic reviews, meta-analyses, and guidelines evaluating the use of compression regimens in the treatment of varicose veins.

Monocyte chemoattractant protein 1 plasma concentration in blood from varicose veins decreases under venoactive drug treatment.

Background: Vein-specific inflammation leads to vascular smooth muscle cells proliferation and extracellular matrix degradation of vein wall. This process is known as remodeling and is promoted by "trapped" leukocytes. Monocyte chemoattractant protein 1 (MCP-1) is a chemokine responsible for trafficking of leukocytes from blood to vein wall.

Thermocatalytic Conversion of Plastics into Liquid Fuels over Clays.

Recycling polymer waste is a great challenge in the context of the growing use of plastics. Given the non-renewability of fossil fuels, the task of processing plastic waste into liquid fuels seems to be a promising one. Thermocatalytic conversion is one of the methods that allows obtaining liquid products of the required hydrocarbon range.

Morphometric properties of immature reticulocytes in health and during acute lymphoblastic and acute myeloid leukemia.

Despite significant advances, many changes occurring in the tumor microenvironment during acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) remain unclear. The surface of immature reticulocytes was examined by atomic force microscopy (AFM) to determine specific changes during the development of ALL and AML. In patients with ALL the surface area of reticulocytes increased by 18.
