Serotonin levels in children with cognitive impairment in delayed speech development in non-alcoholic fatty liver disease with obesity and Covid-19.

Objective: Aim: To identify features of changes in serum serotonin and tryptophan levels in children with cognitive impairment (CI) and delayed speech development (DSD) at non-alcoholic fatty liver disease (NAFLD) and COVID-19.

Patients And Methods: Materials and Methods: The study included 108 children with CI and DSD at NAFLD. The children were divided into 2 groups: group 1 included children with COVID-19 (n=58); group 2 consisted of 50 children without COVID-19.

Synthesis of polydicyclopentadiene using the CpTiCl/EtAlCl catalytic system and thin-layer oxidation of the polymer in air.

The polymerization process of dicyclopentadiene using a multicomponent catalytic system based on bis(cyclopentadienyl)titanium dichloride and diethylaluminum chloride was studied. It was demonstrated that the application of an excess of the aluminum component leads to the formation of stable charged complexes of blue discoloration, which initiate cationic polymerization of dicyclopentadiene. Unstabilized thin layers of obtained polydicyclopentadiene undergo oxidation and structuring under atmospheric oxygen.

Impact of INICC Multidimensional Hand Hygiene Approach in ICUs in Four Cities in Argentina.

We evaluated the impact of the International Nosocomial Infection Control Consortium multidimensional approach to hand hygiene in 11 intensive care units in 4 cities in Argentina and analyzed predictors of poor hand hygiene compliance. We had a baseline period and a follow-up period. We observed 21 100 hand hygiene opportunities.
