Urban ecosystem services research in Russia: Systematic review on the state of the art.

Research on urban ecosystem services (ES) covers many regions globally, yet significant gaps remain in several areas, including Russia. Furthermore, the number of publications on Russian ES is still very low, and most of them focus on ES assessment on the national level which results in an incomplete understanding of ES provision in Russian cities. To fill this gap, 197 publications on urban ES have been systematically reviewed.

COVID-19 pandemic changes the recreational use of Moscow parks in space and time: Outcomes from crowd-sourcing and machine learning.

The limited access to urban green spaces during the COVID-19 pandemic had a negative impact on the human-nature interaction in cities and human well-being. Number of visitors to green areas, initially declined due to imposed restrictions, was restored after they were lifted as established by several studies across the globe However, little is still known about changes in behavior and preferences of park visitors in the post-COVID time. In this study, we investigated spatial-temporal patterns of recreational activities in the three urban parks in Moscow (Russia) prior, during and after the COVID-19 lockdown (in 2019 and 2020).

[Etiopathogenetic principles fo surgical treatment for purulent wounds].

Application of gas-liquid chromatography methods and mass-spectrometry enabled the authors to develop objective criteria, which provided prompt acceptance of quantity information about the stage ams severity of the wound process, its influence on the organism and prognosis of expectant complications (taking into account aerobic or anaerobic components of microflora) and early correction of surgical policy.

[Reconstructive and restorative operations in surgical treatment of suppurative diseases].

The principles of active surgical treatment of purulent wounds made it possible to perform reconstructive operations on 5,422 patients with large purulent wounds and tissue defects. In 3,887 patients the wounds were closed with sutures and drained, in 1,535 patients the wound surfaces were closed and tissue defects repaired by various methods of cutaneo- and osteoplasty, in 1,261 of these patients free skin graft was carried out. In 274 patients wounds in the region of important anatomical structures and functionally active surfaces were closed by transposed vascularized tissues with good cosmetic and functional results.
