Comparative Analysis of the Efficacy of Different Regimens of 12 Months Rifaximin-Alfa Therapy in Patients with Liver Cirrhosis and Minimal Hepatic Encephalopathy.

Unlabelled: It is a matter of current interest which rifaximin-α regimens in patients with liver cirrhosis and minimal hepatic encephalopathy are the most efficient.

Study Objective: to evaluate the effect of various rifaximin-α regimens for 12 months on clinical and laboratory parameters and quality of life in patients with liver cirrhosis and minimal hepatic encephalopathy.

Methods: It was a multicenter, prospective, open-label, observational study that included 288 patients with liver cirrhosis and minimal hepatic encephalopathy of both sexes over the age of 18 years, who were prescribed a 12-month course of treatment with rifaximin-α in accordance with the product label.

[Clinical and laboratory characteristics of arginine vasopressin resistance, caused by a new homozygous mutation p.R113C in AQP2].

Congenital nephrogenic diabetes insipidus (CNDI, arginine vasopressin resistance) is a rare inherited disorder characterized by insensitivity of the kidney to the antidiuretic effect of vasopressin. NDI is clinically characterized by polyuria with hyposthenuria and nocturia and polydipsia. In the majority of cases, about 90%, nephrogenic diabetes insipidus is an X-linked recessive disorder caused by mutations in the AVP V2 receptor gene (AVPR2).

Phase transformation in the "Brodie graphite oxide-acetonitrile" system - influence of the oxidizing level of the material.

Reversible phase transformation in the Brodie graphite oxide-acetonitrile system, which is intercalation or release of part of the sorbed liquid from the interplanar space accompanied by an increase or a decrease in interplanar distances, is commonly observed in twice-oxidized materials. We observed this phenomenon for once-, twice- and thrice-oxidized materials using the EPR spin probe technique, DSC, and temperature programmed XRD. It was shown that all materials under study formed similar low temperature (LT) and high temperature (HT) swollen structures with acetonitrile.

Sorption of Polar Sorbents into GO Powders and Membranes.

The comparative study of sorption of polar substances acetonitrile and water into powders and membranes (>10 μm thick) of modified Hummers (HGO) and Brodie (BGO) graphite oxides was performed using isopiestic method (IM) and differential scanning calorimetry (DSC). Additional sorption data were obtained for pyridine and 1-octanol. Sorption measurements were accompanied by conventional XRD and XPS control.

Hydrocarbons in the water and bottom sediments of Sivash Bay (the Azov Sea) during its salinization.

Sivash Bay is a unique hypersaline lagoon located in the northern part of the Crimean Peninsula. In 2014, due to political events in connection with the closure of the North Crimean Canal, the inflow of fresh water to Sivash Bay has been significantly reduced. As a result, there has been a steady increase in salinity since 2014 to the present.
