The influence of heat and cold waves on mortality in Russian subarctic cities with varying climates.

Publications on ambient temperature-related mortality among Arctic or subarctic populations are extremely rare. While circumpolar areas cover large portions of several European countries, Canada, and the USA, the population of these territories is relatively small, and the data needed for statistical analysis of the health impacts of extreme temperature events are frequently insufficient. This study utilizes standard time series regression techniques to estimate relative increases in cause- and age-specific daily mortality rates during heat waves and cold spells in four Russian cities with a subarctic climate.

The COVID-19 Pandemic: New Knowledge on the Impact of Air Quality on the Spread of Coronavirus Infection in Cities.

Suspended substances in the air form clusters with coronavirus particles and spread up to 10 m from the source of infection. The importance of taking air pollution into account when simulating the spread of the COVID-19 pandemic is due to the similarity in the health impacts made by the coronavirus and the respirable fraction of suspended solids. In Europe, up to 6.

Chromatin-Associated Membraneless Organelles in Regulation of Cellular Differentiation.

Membrane-free intracellular biocondensates are enclosures of proteins and nucleic acids that form by phase separation. Extensive ensembles of nuclear "membraneless organelles" indicate their involvement in genome regulation. Indeed, nuclear bodies have been linked to regulation of gene expression by formation of condensates made of chromatin and RNA processing factors.

BART-Seq: cost-effective massively parallelized targeted sequencing for genomics, transcriptomics, and single-cell analysis.

We describe a highly sensitive, quantitative, and inexpensive technique for targeted sequencing of transcript cohorts or genomic regions from thousands of bulk samples or single cells in parallel. Multiplexing is based on a simple method that produces extensive matrices of diverse DNA barcodes attached to invariant primer sets, which are all pre-selected and optimized in silico. By applying the matrices in a novel workflow named Barcode Assembly foR Targeted Sequencing (BART-Seq), we analyze developmental states of thousands of single human pluripotent stem cells, either in different maintenance media or upon Wnt/β-catenin pathway activation, which identifies the mechanisms of differentiation induction.
