Stability of DMPC Liposomes Externally Conjugated with Branched Polyglycerol.

Vesicles formed by DMPC liposomes externally conjugated with branched polyglycerol-dendrons as well as linear PEG in water solution were simulated using the DPD method. Such a structure of vesicles corresponds to the structure of polymer-grafted liposomes obtained experimentally by the post-insertion method, in which polymer chains are fixed on the outer surface of the liposome. The grafting density, generation number and spacer length of grafted dendrons were varied.

Immunohistochemical Expression of VDR in Myocardium: Postmortem Evaluation of COVID-19 Patients.

Morphological data on heart damage and its mechanisms due to extremely severe course of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection are limited, as well as data on the correlation of damage and expression of vitamin D receptors (VDRs). In this study, we analyzed a series of myocardial samples obtained during postmortem autopsy of 48 critically ill patients with COVID-19 who died with SARS-CoV-2-associated pneumonia. The purpose of the study was to evaluate immunohistochemical VDR expression in the myocardium.

The Advanced Aluminum Nitride Synthesis Methods and Its Applications: Patent Review.

Background: High purity nanosized aluminum nitride synthesis is a current issue for both industry and science. However, there is no up-to-date review considering the major issues and the technical solutions for different methods. This review aims to investigate the advanced methods of aluminum nitride synthesis and its development tendencies.

[EXPERIENCE OF THE MULTIPLE ENVIRONMENTAL ASSESSMENT OF RISKS FOR POPULATION'S HEALTH WITH THE AIM TO PROVIDE THE SAFETY OF THE POPULATION OF THE CITY OF CHELIABINSK].

For the purposes of the determination of reasons for the high cancer rates in the population ofthe city of Chelyabinsk there was performed the multiple environmental assessment of the carcinogenic risk from chemicals dissolved in drinking water, food, soil, air (from stationary sources). Based on this assessment there were determined the directions for sanitary and environmental measures.

[Inhalation risk upon exposure to emission from industrial enterprises in the town of Magnitogorsk].

Based on the risk assessment methodology, the authors gives information on Magnitogorsk priority industrial enterprises; the chemicals contained in their emission from halation risk, which are responsible for moderare and severe risks. Negative health effects due to chronic inhalation exposure and the poorest environmental areas under observation are identified. The directions of application of the findings are specified.
