The effectiveness of biopreparations in soft wheat cultivation and the quality assessment of the grain by the digital x-ray imaging
The main trend of modern crop production is the expansion of the use of plant
protection solutions and technologies, that ensure not only effective management of the number
of populations of harmful organisms, but also the production of environmentally safe agricultural
products with minimal anthropogenic impact on agro-ecosystems. One of our priorities is to
develop new environmentally sound polyfunctional biopreparations, that combine useful
properties of microbial strains such as phytopathogen antagonists and chitosan compositions that
increase disease resistance. The introscopic analysis of the seed material quality realized with the
non–destructive express techniques application was used for evaluation the effectiveness of the
compositions' complex influence on plants. The research studies the effectiveness of the influence
of Bacillus subtilis strains and chitosan compositions, including their combined effect, on soft
wheat productivity and its damage by disease agents. Data on the quality assessment of the grain
using microfocus x-ray radiography and gas-discharge visualization (electrophotography) are
also provided. The complex of more than 20 structural elements of wheat productivity was
analysed during the research. Assessment of the plant damage intensity according to the standard
criterion – the disease development, and additional phytopathological indicators was carried out.
The evaluation of the grains’ introscopic characteristics was carried out by the microfocus x-ray
radiography techniques combined with the digital x-ray image analysis. It is shown that the
biopreparation complexes, containing B. subtilis strains and Chitosan, have a combined
biological activity manifested in the optimization of wheat plants’ physiological state, increasing
productivity, diseases resistance
SiPM MEPhI Megagrant Developments in Nuclear Medicine
AbstractThree projects has been started in our laboratory as part of megagrant “High energy physics and nuclear medicine with silicon photomultiplier detectors” in NRNU MEPHI. The goal of these projects is development of devices for nuclear medicine in which replacement of photomultiplier tubes (PMT) with solid-state silicon photomultipliers promises various advantages. The first project is full-body SPECT, where replacement of PMT's could reduce size of the detector module and improve spatial resolution while keeping other parameters. The second project is development of a TOF-PET module. Replacement of PMTs with silicon photomultipliers makes it possible to use that detector not only in high magnetic fields but also for Time-of-Flight measurements (higher signal-to-noise ratio on final image) due to very high timing resolution of a SiPM. And the last project is the SiPM-based position-sensitive Gamma-spectrometer for dose monitoring in neutron-capture therapy based on SiPM's
Study of reproduction cycles and yield dynamics of the classical swine fever virus in PK-15 cultured cells using a fluorescent probes technique
The authors have elaborated some methodological approaches necessary to solve certain biotechnological problems. This approaches permit to study the classical swine fever virus reproduction and accumulation in a swine established cell line, PK-15, the virus propagation being accompanied with no cytopathic effect. The reliable and promising fluorescent probe technique needing no previous virus adaptation and multiplication in permissive cells is successfully confirmed to be useful for such purposes.Розроблено важливу для вирішення біотехнологічних проблем методологію вивчення циклів розмноження та динаміки накопичення вірусу класичної чуми свиней в культурі перевивних клітин РК-15 за умов відсутності будь-яких проявів цитопатогенної дії вірусу.

Association of Polymorphisms of Serotonin Transporter (5HTTLPR) and 5-HT2C Receptor Genes with Criminal Behavior in Russian Criminal Offenders
Background: Human aggression is a heterogeneous behavior with biological, psychological, and social backgrounds. As the biological mechanisms that regulate aggression are components of both reward-seeking and adversity-fleeing behavior, these phenomena are difficult to disentangle into separate neurochemical processes. Nevertheless, evidence exists linking some forms of ag
Genetic deletion of trace-amine associated receptor 9 (TAAR9) in rats leads to decreased blood cholesterol levels
In the last two decades, interest has grown significantly in the investigation of the role of trace amines and their receptors in mammalian physiology and pathology. Trace amine-associated receptor 9 (TAAR9) is one of the least studied members of this receptor family with unidentified endogenous ligands and an unknown role in the central nervous system and periphery. In this study, we generated two new TAAR9 knockout (TAAR9-KO) rat strains by CRISPR-Cas9 technology as in vivo models to evaluate the role of TAAR9 in mammalian physiology. In these mutant rats, we performed a comparative analysis of a number of hematological and biochemical parameters in the blood. Particularly, we carried out a complete blood count, erythrocyte osmotic fragility test, and screening of a panel of basic biochemical parameters. No significant alterations in any of the hematological and most biochemical parameters were found between mutant and WT rats. However, biochemical studies revealed a significant decrease in total and low-density lipoprotein cholesterol levels in the blood of both strains of TAAR9-KO rats. Such role of TAAR9 in cholesterol regulation not only brings a new understanding of mechanisms and biological pathways of lipid exchange but also provides a new potential drug target for disorders involving cholesterol-related pathology, such as atherosclerosis
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
