Urolithin A increases the natural killer activity of PBMCs in patients with prostate cancer.

Background: The natural killer (NK) activity of peripheral blood mononuclear cells (PBMCs) is a crucial defense against the onset and spread of cancer. Studies have shown that patients with reduced NK activity are more susceptible to cancer, and NK activity tends to decrease due to cancer-induced immune suppression. Enhancing the natural cytotoxicity of PBMCs remains a significant task in cancer research.

Sociodemographic Factors Associated with Purchasing Frozen, Fresh, Canned, and Dried Produce in a Nationally Representative Sample of United States Households.

Background: Frozen fruits and vegetables (FV) are convenient, cost-effective, reduce food waste, and can be just as nutritious as their fresh counterparts. Despite these numerous advantages, it is unclear which consumer segments are more likely to purchase frozen FV, especially compared with fresh, canned, or dried FV, which could help inform targeted nutrition education interventions.

Objective: The objective of this study is to explore sociodemographic factors associated with increased or decreased odds of purchasing frozen, fresh, canned, and dried FV in a nationally representative sample.

Periodontal pathogens and obesity in the context of cardiovascular risks across age groups.

Background: Cardiovascular diseases (CVDs) are the leading cause of mortality and morbidity among noncommunicable diseases. Over the past decade, there has been a notable increase in the prevalence of CVDs among young individuals. Obesity, a well-known risk factor for CVDs, is also associated with various comorbidities that may contribute to cardiovascular risk.

Clinical case of co-infection: Dengue fever and respiratory mycoplasmosis in a child.

According to WHO, dengue fever (DF) is currently endemic to more than 100 countries in various regions of Africa, America, and Asia; outbreaks have been reported in Europe. In the Russian Federation, there is a much smaller proportion of children among those infected due to the imported nature of the infection. We described a clinical case of imported dengue fever in an adolescent girl in Moscow after a 5-day vacation.

Fluorescence lifetime imaging in drug delivery research.

Once an exotic add-on to fluorescence microscopy for life science research, fluorescence lifetime imaging (FLIm) has become a powerful and increasingly utilised technique owing to its self-calibration nature, which affords superior quantification over conventional steady-state fluorescence imaging. This review focuses on the state-of-the-art implementation of FLIm related to the formulation, release, dosage, and mechanism of action of drugs aimed for innovative diagnostics and therapy. Quantitative measurements using FLIm have appeared instrumental for encapsulated drug delivery design, pharmacokinetics and pharmacodynamics, pathological investigations, early disease diagnosis, and evaluation of therapeutic efficacy.

Structural studies of hydrated rare earth nitrates within the stereoatomic model of crystal structures.

All crystal structures containing nitrate ions, water molecules and one of the rare earth (RE) metal atoms (La-Lu, Y, Sc) were extracted from the Inorganic Crystal Structure Database. The composition of the identified compounds is analyzed in terms of the number of coordinated and uncoordinated water molecules and nitrate ions. Among the resulting compounds, several isotypic and morphotropic series are observed.

Study of the Pharmacological Activity Spectrum of the New Original NT-3 Mimetic Dipeptide GTS-302.

Unlabelled: The association of the pathogenesis of neurodegenerative diseases, depression, anxiety, and cognitive disorders with neurotrophin-3 deficiency determines the prospect of creating drugs with a similar mechanism of action. Since the use of full-length NT-3 is limited by unsatisfactory pharmacokinetic properties, the creation of low-molecular mimetics of neurotrophin-3 that are active when administered systemically is relevant. The Federal Research Center for Innovator and Emerging Biomedical and Pharmaceutical Technologies has created a dimeric dipeptide mimetic of the 4th loop of NT-3, hexamethylenediamide bis-(N-γ-oxybutyryl-L-glutamyl-L-asparagine) with the laboratory code GTS-302, which activates TrkC and TrkB receptors.

Parametric Search for Optimal Channel Shape for Swirling Blood Flow in the Heart and Main Vessels.

The study presents a numerical parametric investigation of flow structures in channels with a longitudinal-radial profile zR = Const and a spherical dome at the base. The goal of the study was to examine the flow structures in these channels depending on the exponent N of the profile and the height of the dome, to determine the conditions that provide optimal centripetal swirling flow, analogous to blood flow in the heart chambers and major vessels. The investigation was conducted using a comparative analysis of flow structures in channel configurations zR = Const, carried out in two stages.

Influence of Retrodipeptide Analogue of Cholecystokinin Tetrapeptide (GB-115) and Phenazepam on the Behavior of Rhesus Monkeys under Isolation Conditions.

Introduction: The developed domestic retrodipeptide analogue of cholecystokinin tetrapeptide (CCK) (N-(6-phenylhexanoyl)-glycyltryptophan amide, or compound GB-115) with antagonistic properties in relation to CCK1 receptors has anxiolytic activity previously shown in preclinical and clinical studies. The aim of the study was to evaluate the anxiolytic effect of GB-115 as a tablet form with subchronic oral administration in comparison with phenazepam in nonhuman primates.

Materials And Methods: The study was conducted on four male rhesus monkeys (Macaca mulatta) aged 5.

Transcriptomic Shifts in Multipotent Mesenchymal Stromal Cells during Microgravity Simulation.

One of the most obvious manifestations of the negative impact of space flight factors on the human physiology is osteopenia. With the active development of manned space flights and the increase in the duration of humans' persistence in weightlessness, there is a growing need to understand the mechanisms of changes occurring at the cellular level involved in the replenishment of bone tissue. Using the RNA sequencing method, changes in the transcriptome profile of MMSCs were studied after a 5-day simulation of the microgravity effects.

Omega-3 Docosahexaenoic Acid as a Promising Inducer of Ferroptosis: Dynamics of Action in Prostate and Colorectal Cancer Models.

Ferroptosis is an iron-dependent form of programmed cell death (PCD) associated with lipid membrane peroxidation. It has gained attention in cancer research because some tumor cells that are resistant to other forms of PCD are sensitive to ferroptosis. Despite the significant amount of research on ferroptosis, the list of known inducers remains limited, creating opportunities to discover new compounds with clinical potential.

New N-Substituted Adenine Derivatives with High Antiviral Activity against RNA-Containing Viruses.

In this work, two new compounds, N-(4,5-dimethoxyphenyl)adenine and N-(3,5-di-trifluoromethylphenyl)adenine, with a broad range of antiviral activity against RNA viruses were identified. We showed that these compounds exhibit pronounced antiviral activity against human poliovirus types 1, 2, and 3, belonging to enterovirus C species. Both compounds also demonstrated pronounced antiviral activity against Coxsackie viruses B3, B5, and B6, belonging to enterovirus B species.

Ascorbate Biosynthesis and Recycling Genes Are Involved in the Responses of Garlic Allium sativum L. Plants to Fusarium proliferatum Infection.

The expression profile of the key genes of biosynthesis (VTC2, GPP, GalDH, and GalLDH) and recycling (MDHAR1, MDHAR4, and MDHAR5) of ascorbate in response to infection with the fungal pathogen Fusarium proliferatum in garlic cultivars resistant (Podnebesny) and sensitive (Dubkovsky) to Fusarium rot was determined. It was found that differences in resistance to Fusarium lead to discrepancies in the dynamics and expression of individual genes of the ascorbate pathway, as well as in the ascorbate content. It was shown that, in response to infection, the expression level of the MDHAR4 gene increases in the resistant cultivar and decreases in the Fusarium-sensitive accession.

Analgesic Activity of the Low Molecular Weight Neurotrophin-3 Dipeptide Mimetic GTS-301.

It was previously shown that the original dipeptide mimetic of the 4th loop of neurotrophin-3 (NT-3) hexamethylenediamide bis-(N-monosuccinyl-L-asparaginyl-L-asparagine) (GTS-301), like the full-length neurotrophin, predominantly activates the tyrosine kinase receptor TrkC and has a neuroprotective effect in vitro at concentrations of 10-10 M, as well as antidiabetic (0.1 and 0.5 mg/kg) and antidepressant (5 and 10 mg/kg) effects after systemic administration in rodents.

Mechanisms of Antitumor Activity of Low Doses of Radiation Associated with Activation of Cells' Defense System.

Background: The effects of ionizing radiation (IR) involve a highly orchestrated series of events in cells, including DNA damage and repair, cell death, and changes in the level of proliferation associated with the stage of the cell cycle. A large number of existing studies in literature have examined the activity of genes and their regulators in mammalian cells in response to high doses of ionizing radiation. Although there are many studies, the research in effect of low doses of ionizing radiation remains limited.

Nudibranch Coryphella trophina (Bergh, 1890) (Gastropoda, Nudibranchia) Uses Twice Stolen Nematocysts for Its Defense.

Most nudibranchs feed on hydroids and anemones and utilize kleptocnidae, which are stinging capsules stolen from eaten victims, for their own defense. The nudibranch Coryphella trophina (Bergh, 1890) was found to eat other nudibranchs. Stinging capsules that the predator uses for its defense have been stolen twice: first by mollusks feeding on cnidarians and then by C.

Expression of HOX Cluster Genes in Early Larval Development of Sea Urchin Strongylocentrotus intermedius (Echinodermata, Echinoidea).

Expression of 11 genes of the Hox cluster (SiHox1, 2, 3, 5, 6, 7, 8, 9/10, 11/13a, 11/13b, and 11/13c) was assessed in the sea urchin Strongylocentrotus intermedius at early developmental stages, including the blastula (13 h post fertilization (hpf)), gastrula (35 hpf), prism (46 hpf), and pluteus (4 and 9 days post fertilization (dpf)) stages. Expression of SiHox7, 11/13b, and 11/13c was observed at the blastula stage; early activation of 11/13c was detected for the first time in regular sea urchins. The expression level was very low at the gastrula and prism stages.

In Vivo UV-Induced Fluorescence Spectroscopy of Skin in Parkinson's Disease.

Characteristic patterns of UV-induced skin autofluorescence were determined for patients with Parkinson's disease (PD) and associated with dysmetabolic alterations, such as nonenzymatic protein glycation, an increase in extracellular matrix stiffness, impaired metabolism of tissue fluorophores, mitochondrial dysfunction, and accumulation of aberrant proteins. Key differences in skin autofluorescence spectra were for the first time observed in PD, making it possible to discriminate between PD patients and healthy persons or individuals without signs of chronic neurodegeneration. Namely, skin fluorescence related to the reflected signal upon excitation with UV light at 375 nm was lower in PD patients.

SUMOylation of TRIM28 is positively modulated by the BTB/POZ domain of Kaiso.

Background: TRIM28 plays a crucial role in maintaining genomic stability and establishing imprinting, facilitated by the diversity of KRAB zinc finger proteins. The SUMOylation of TRIM28 is essential for its function and is enhanced in the presence of the KRAB domain. Previously, we demonstrated that Kaiso, another factor capable of interacting with TRIM28, can promote its SUMOylation.

Centriolar cap proteins CP110 and CPAP control slow elongation of microtubule plus ends.

Centrioles are microtubule-based organelles required for the formation of centrosomes and cilia. Centriolar microtubules, unlike their cytosolic counterparts, are stable and grow very slowly, but the underlying mechanisms are poorly understood. Here, we reconstituted in vitro the interplay between the proteins that cap distal centriole ends and control their elongation: CP110, CEP97, and CPAP/SAS-4.
