Comparative Analysis of Plasma Protein Dynamics in Women with ST-Elevation Myocardial Infarction and Takotsubo Syndrome.

Background: ST-elevation myocardial infarction (STEMI) and Takotsubo syndrome (TS) are two distinct cardiac conditions that both result in sudden loss of cardiac dysfunction and that are difficult to distinguish clinically. This study compared plasma protein changes in 24 women with STEMI and 12 women with TS in the acute phase (days 0-3 post symptom onset) and the stabilization phase (days 7, 14, and 30) to examine the molecular differences between these conditions.

Methods: Plasma proteins from STEMI and TS patients were extracted during the acute and stabilization phases and analyzed via quantitative proteomics.

Ischemic preconditioning affects phosphosites and accentuates myocardial stunning while reducing infarction size in rats.

Background And Aims: Ischemic preconditioning (IPC), i.e., brief periods of ischemia, protect the heart from subsequent prolonged ischemic injury, and reduces infarction size.

[Circulation of bovine herpesvirus (Herpesviridae: ) and bovine viral diarrhea virus (Flaviviridae: ) among wild artiodactyls of the Moscow region].

Introduction: Pestiviruses and viruses of the Herpesviridae family are widely distributed among different species of ungulates, but the main information about these pathogens is related to their effect on farm animals. Data on detection of bovine viral diarrhea virus (BVDV) and bovine herpes virus (BoHV) in wild ungulates reported from different countries in recent years raises the question of the role of wild animals in the epidemiology of cattle diseases.

Aim Of Work: To study the prevalence of herpesviruses and pestiviruses in the population of wild artiodactyls of the Moscow region.

The Effect of Disinfectants on the SARS-CoV-2 RNA Detection in Swabs from Various Surfaces.

The COVID-19 pandemic has spread rapidly around the world; some countries have introduced controls on imported products, including testing for viral nucleic acids. In this work, the influence of disinfectants for treating various SARS-CoV-2-contaminated surfaces on the detection of viral RNA fragments in swabs from these surfaces was analyzed using quantitative RT-PCR. Quaternary ammonium salt, hydrogen peroxide, 1-propanol, and sodium salt of dichloroisocyanuric acid, as well as ultraviolet irradiation, were tested as such disinfecting agents.

The first study on the occurrence of bovine herpesviruses in the wild fauna of the Moscow region, Russia.

Background And Aim: Some pathogens that cause infections in cattle are found in wild artiodactyls. Their prevalence, possible impact on the population of free-living animals, and the spread of infectious pathology in livestock have yet to be studied. We investigated the occurrence of bovine herpesviruses (BoHV-1, BoHV-4, and BoHV-6) among wild moose and roe deer in 8 areas of the Moscow region in the Russian Federation.

The Hordeum bulbosum 25S-18S rDNA region: comparison with Hordeum vulgare and other Triticeae.

Hordeum vulgare and Hordeum bulbosum are two closely related barley species, which share a common H genome. H. vulgare has two nucleolar organizer regions (NORs), while the NOR of H.

Peculiar evolutionary history of miR390-guided TAS3-like genes in land plants.

PCR-based approach was used as a phylogenetic profiling tool to probe genomic DNA samples from representatives of evolutionary distant moss taxa, namely, classes Bryopsida, Tetraphidopsida, Polytrichopsida, Andreaeopsida, and Sphagnopsida. We found relatives of all Physcomitrella patens miR390 and TAS3-like loci in these plant taxa excluding Sphagnopsida. Importantly, cloning and sequencing of Marchantia polymorpha genomic DNA showed miR390 and TAS3-like sequences which were also found among genomic reads of M.

TAS3 Genes for small ta-siARF RNAs in plants belonging to subtribe Senecioninae: occurrence of prematurely terminated RNA precursors.

The various classes of plant 21 - to 24-nt siRNAs derive from long dsRNA precursors that are processed by the ribonuclease Dicer-like (DCL). The species of ta-siRNA were originally discovered in Arabidopsis thaliana. Four gene families have been identified in Arabidopsis that each produces a number of ta-siRNAs: TAS1, TAS2, TAS3 and TAS4.

Novel miR390-dependent transacting siRNA precursors in plants revealed by a PCR-based experimental approach and database analysis.

TAS loci in plant genomes encode transacting small interfering RNAs (ta-siRNAs) that regulate expression of a number of genes. The function of TAS3 precursor in Arabidopsis thaliana is controlled by two miR390 target sites flanking two ta-siARF sequences targeting mRNAs of ARF transcription factors. Cleavage of the 3'-miR390-site initiates ta-siRNAs biogenesis.
