The study of viral communities has revealed the enormous diversity and impact these biological entities have on various ecosystems. These observations have sparked widespread interest in developing computational strategies that support the comprehensive characterisation of viral communities based on sequencing data. Here we introduce VIRify, a new computational pipeline designed to provide a user-friendly and accurate functional and taxonomic characterisation of viral communities.

Zebra mussels (ZM), Dreissena polymorpha (Pallas, 1771), are one of the most aggressive invasive species. ZM have a strong bidirectional impact on phytoplankton because of their high nutrient excretion rates and high grazing pressure. Furthermore, the interactions between excretion and selective grazing are related to the trophic status of a waterbody and could cause unpredictable changes in phytoplankton.

An increasingly common output arising from the analysis of shotgun metagenomic datasets is the generation of metagenome-assembled genomes (MAGs), with tens of thousands of MAGs now described in the literature. However, the discovery and comparison of these MAG collections is hampered by the lack of uniformity in their generation, annotation and storage. To address this, we have developed MGnify Genomes, a growing collection of biome-specific non-redundant microbial genome catalogues generated using MAGs and publicly available isolate genomes.

Besides its use in medicine, vitamin B (cobalamin) and its derivatives have found in numerous applications as catalysts. However, studies related to the activation of oxidants via cobalamin are scant. In this work, we showed how the addition of aquacobalamin (HOCbl) accelerates the destruction of azo-dye Orange II by peroxymonosulfate (HSO) in aqueous solutions.

Article Synopsis
  • The study assessed the real-life effectiveness and safety of erenumab in treating migraine in 33 patients, primarily females with an average age of 39.2 years.
  • During the treatment, a significant 50% reduction in headache days was reported by nearly half of the patients across the first three months, along with improvements in pain intensity and the impact on daily activities as measured by HIT-6 scores.
  • Side effects were minimal, with only one instance of transient constipation, suggesting that erenumab is both effective and safe for outpatient use in managing migraines.

Comprehensive, high-quality reference genomes are required for functional characterization and taxonomic assignment of the human gut microbiota. We present the Unified Human Gastrointestinal Genome (UHGG) collection, comprising 204,938 nonredundant genomes from 4,644 gut prokaryotes. These genomes encode >170 million protein sequences, which we collated in the Unified Human Gastrointestinal Protein (UHGP) catalog.

Background: High-throughput sequencing often provides a foundation for experimental analyses in the life sciences. For many such methods, an intermediate layer of bioinformatics data analysis is the genomic signal track constructed by short read mapping to a particular genome assembly. There are many software tools to visualize genomic tracks in a web browser or with a stand-alone graphical user interface.

Aim: To evaluate the association of the DRD2 gene and DRD2 x HTR2C interaction with hedonic and activational aspects of approach motivation in schizophrenia.

Material And Methods: Genotypes at polymorphic loci DRD2 rs1800497 and HTR2C rs6318 (Cys23Ser) were identified in a sample that included 174 patients with schizophrenic spectrum disorders and 268 healthy subjects without a family history of psychoses. The participants completed the BIS/BAS and Temporal Experience of Pleasure Scale (TEPS).

Unlabelled: The background: the increased frequency of serious consequences of perinatal lesions in the central nervous system of the young children dictates the necessity to develop the effective methods of physiotherapy for the early-stage rehabilitation of such patients on the basis of an objective assessment of the adaptive reserves of the organism.

Material And Methods: The present study involved 53 children at the age from 1 to 12 months presenting with the consequences of perinatal lesions to the central nervous system. Thirty of the children were treated with the use of electrophoresis in the form of Polymineral wipes on the basis of natural iodine-bromine water.

The paper gives the results of sequence analysis of 150 positive samples in real-time RT-PCR, including 47 autopsy materials from patients (including 10 pregnant women), who died from fatal pneumonia mainly in November-December 2009, in whom the lifetime etiological diagnosis had not been made and hence no early etiotropic therapy performed. 70% of the primary materials from the deceased patients were found to have pandemic influenza A(H1N1) v mutants in the lung tissue with D222G (15%), D222N (15%), D222E (2%) substitutions, as well as a mixture of mutants (38%). Nasopharyngeal lavages from 3 Chukotka deceased patients exhibited only consensus (nonmutant) D222 virus variants; there was a mixture of consensus and mutant virus variants in the trachea and a mixture of mutant ones in the lung.

Blood serum samples collected from patients with acute hepatitis symptoms admitted to Infectious Disease Hospitals of Novosibirsk, Barnaul, and Irkutsk were studied. The serum samples were tested for the IgM and IgG antibodies to HEV using ELISA. Seropositive samples were tested using RT-PCR for HEV RNA.

The course of anesthesia during uterine extirpation for large and giant myomas depends on the efficiency of blood loss compensation and relative hypovolemia after rapid decompensation when a mass is removed. Thirty-five patients with a uterine myoma with the size corresponding to 18-40-week gestation were examined. Dextrans and voluven (hydroxyethylstarch 130/0.

Comparative study of replication markers of hepatitis C virus in various biological substrates and evaluation of activity of chronic HCV infection in liver biopsy specimens showed that replication of hepatitis C virus and the number of HCV-infected hepatocytes did not promote liver damage in chronic hepatitis C. These findings indicate that the expression of antiviral reactions by liver parenchyma cells plays the key role in the morphogenesis of HCV infection.

We carried out a comparative study of replication markers of hepatitis C virus (HCV RNA) in some biological substrates and NS3-antigen in liver biopsy specimens. It was found that 82% liver specimens contained RNA HCV, in 44% cases HCV RNA was present in the serum, mononuclear blood cells, and liver. The presence of NS3-antigen in hepatocytes can be considered as a structural marker of HCV replication, which is confirmed by positive correlation with the results of PCR for viral RNA in tissue specimens.

The authors validate the necessity of hygienic certification including microbiological control of perfumes and cosmetics, to which oral hygiene means belong. They consider that the absence of sanitary regulations for some goods, toothpastes included, is one of the causes, responsible for the absence of a proper sanitary control on the part of State Epidemiological Survey of the Russian Federation. In accordance with the resolution "On Certification of Perfumes and Cosmetics" issued in 1994, Central Research Institute of Stomatology is appointed the central institution responsible for certification of means of oral hygiene, and at present its main task is development of sanitary regulations, standards, methods of investigation, and training of personnel for institutions which are to carry out certification.

Functional activity of local immunity with regard to dental caries in children is liable to appreciable individual fluctuations which depend on sex, age, and season. In children aged 4 to 5 no association between the titer of antibodies to cariogenic Streptococcus and number of carious lesions was observed, whereas in those aged 9 to 19 these parameters were in inverse relationship. In children aged 11-12 and 14-16 this association is inverse.
