Multidecadal declines in particulate mercury and sediment export from Russian rivers in the pan-Arctic basin.

SignificanceRussian rivers are the predominant source of riverine mercury to the Arctic Ocean, where methylmercury biomagnifies to high levels in food webs. Pollution controls are thought to have decreased late-20th-century mercury loading to Arctic watersheds, but there are no published long-term observations on mercury in Russian rivers. Here, we present a unique hydrochemistry dataset to determine trends in Russian river particulate mercury concentrations and fluxes in recent decades.

Description of local carbon flux from large scale gridded climate data by a dynamic global vegetation model at variable time steps: Example of Euroflux sites.

Dynamic Global Vegetation Models (DGVMs) are commonly used to describe the land biogeochemical processes and regulate carbon and water pools. However, the simulation efficiency and validation of DGVMs are limited to varying temporal and spatial resolutions. Additionally, the uncertainties caused by different interpolation methods used in DGVMs are still not clear.

Outcomes of hypertrophic obstructive cardiomyopathy patients undergoing alcohol septal ablation with a standard 3 mL dose of ethanol: Focus on long-term safety.

Objectives: The objective of this research was to assess the long-term results of alcohol septal ablation in patients with hypertrophic obstructive cardiomyopathy (HOCM), with all of them receiving a standard 3 mL ethanol dose.

Background: Generally, ethanol (0.5-3 mL) is infused depending on a septal artery width or interventricular septum (IVS) thickness during alcohol septal ablation.

Results of Ten-Year Follow-Up of Alcohol Septal Ablation in Patients with Obstructive Hypertrophic Cardiomyopathy.

This study looks at 10-year follow-up outcomes of alcohol septal ablation in patients with obstructive hypertrophic cardiomyopathy. Between 2000 and 2008, 40 patients with obstructive hypertrophic cardiomyopathy (27 males, 13 females) underwent alcohol septal ablation. The median follow-up period was 123 (2-179) months.

[Surgical treatment of patients with leiomyosarcoma of inferior vena cava].

Aim: To evaluate the results of surgical treatment of patients with leiomyosarcoma of inferior vena cava.

Material And Methods: For the period 2003-2016 21 patients with leiomyosarcoma of IVC were operated at the abdominal department of Blokhin Russian Cancer Research Center. 23.
