Psoriasis is a common chronic inflammatory skin condition that varies in severity. Psoriasis is associated with complex disorders, which incorporate metabolic syndrome, obesity and impaired glucose tolerance. Adipose tissue secretes several hormones and cytokines, in particular visfatin and resistin that could be involved in the development of psoriasis by acting as pro-inflammatory or immunoregulatory factors. The aim of this work was to evaluate the serum level of visfatin and resistin as well as of high-sensitivity C-reactive protein (hs-CRP) and erythrocyte sedimentation rate (ESR) in psoriatic patients. The study included 43 healthy individuals and 45 patients divided into three groups with mild, moderate and severe clinical degrees of disease assessed by the Psoriasis Area Severity Index (PASI). The results showed a significant increase in the concentration of serum visfatin, resistin, ESR and hs-CRP in patient groups in comparison with a control group. The highest increase in indicators was observed in the group of patients with severe disease compared with the mild and moderate patients groups. The significance of studied indicators as biomarkers of psoriasis disease severity is analyzed.

Obstructive sleep apnea syndrome (OSAS) is a disease characterized by repetitive, partially or complete upper airway obstructions resulting in hypoxia and bioelectrical wakefulness reactions along with sleep. There is a limited and different information on the biochemical pathways that may determine harmful effects in OSAS patients with different disease severity. Hence, we aimed to estimate the plasma levels of polyamine agmatine, which has many effects on the central nervous system, telomerase and trace minerals in patients with OSAS. The study included 90 volunteer patients diagnosed with OSAS and divided into three groups of 30 people each according to the apnea-hypopnea index (AHI) score: mild, moderate and severe. Nocturnal blood oxygen saturation percentage (SpO2) and body mass index (BMI) were measured. Plasma agmatine level was defined by ultra-high-pressure liquid chromatography (UHPLC), plasma trace elements (Cu, Co, Mg, Mo, Zn, Se) level by inductively coupled plasma mass spectrometer (ICP-MS) and serum telomerase level by enzyme-linked immunosorbent assay (ELISA) method. It was found that SpO2 value decreased as the disease progressed and showed a negative correlation with BMI, Co and Se plasma levels. The levels of agmatine and telomerase were shown to lower in patients with severe OSAS group compared to other groups.

The development of a new anticancer drugs targeted at energy metabolism of tumor cells is a promising approach for cancer treatment. The aim of our study was to investigate the action of thiazole derivative N-(5-benzyl-1,3-thiazol-2-yl)-3,5-dimethyl-1-benzofuran-2-carboxamide (BF1) and its complex with PEG based polymeric nanoparticle (PEG-PN) on respiration and mitochondrial membrane potential in murine NK/Ly tumor cells. The rate of oxygen uptake in NK/Ly cells was recorded by a polarographic method using a Clark electrode. The mitochondrial potential relative values were registered using fluorescence TMRM dye. No changes in glucose-fuelled basal respiration or maximal FCCP-stimulated respiration was detected after 15-min incubation of cells with BF1 (10 µM), PEG-PN or BF1 + PEG-PN complex Fluorescent microscopy data showed that BF1 or PEG-PN separately had no effect on the value of mitochondrial membrane potential, while BF1 + PEG-PN complex caused a significant decrease in mitochondrial membrane potential, indicating on the decrease of NK/Ly cells viability.

Thiosulfonates are characterized by a wide spectrum of biological activity and have effective antimicrobial, antithrombotic, antitumor and antiparasitic effects. However, the use of synthetic sulfur-containing compounds for therapeutic and preventive purposes requires the study of their effect on the protective mechanisms of maintaining homeostasis, the antioxidant status of the body in particular. The aim of the study was to estimate lipid peroxidation process and the state of the antioxidant system in the kidneys, spleen, brain, and muscles of rats under the influence of newly synthesized sulfur-containing compounds of S-alkyl esters of thiosulfonic acids S-ethyl-4-aminobenzenethiosulfonate (ETS), S-allyl-4-aminobenzenethiosulfonate (ATS) and S-allyl-4-acetylaminobenzenethiosulfonate (AATS). Male Wistar rats kept on a standard diet were divided into four groups of 5 animals each: I (control), II, III, IV (experimental). The animals of the control group received additional 0.5 ml of oil and the animals of the experimental groups 0.5 ml of oil solution of thiosulfonate esters once a day. The animals of II, III and IV groups were given ETS, ATS, AATS at the rate of 100 mg per kg of body weight. The lipid hydroperoxides (LPH), TBA-active products, GSH content and activity of SOD, catalase, glutathione peroxidase, glutathione reductase in tissue homogenates were determined. The multidirectional changes of the studied indicators after consumption of S-alkyl esters of thiosulfonic acids for 21 days have been identified and characterized indicating on different degree of inhibition or activation of LPO processes depending on the type of tissue and the structure of thiosulfonate ester.

Ovarian cancer (OC) is the most lethal gynecological cancer. Multiple genetic and epigenetic abnormalities have been detected in ovarian cancers. As microRNAs (miRNAs) play important roles in carcinogenesis, numerous researchers aim to determine the molecular mechanism that regulates the cancer cells proliferation and metastasis. In the current study, the expression of microRNA-613 and related KRAS and Ezrin genes was assessed by Real-time PCR in ovarian cancer tissue and the adjacent apparently normal tissues. Our results revealed that the expression of miRNA-613 was downregulated in ovarian cancer while the expression of KRAS and Ezrin was higher in cancer tissues compared to apparently normal ovarian tissues. There was a negative correlation between the expression of miRNA-613 and both KRAS and Ezrin genes expression and a positive correlation between KRAS and Ezrin gene expression. The results obtained confirm that miRNA-613 acts as a tumor-suppressive gene in ovarian cancer and can realize such impact through the expression of KRAS and Ezrin genes. These data contribute to the identification of potential biomarkers and novel targets for OC early detection and treatment.

Because of the catastrophic consequences of COVID-19 on the world population, there should be novel interventions to handle ongoing infections and daily death cases. The aim of the current study is to examine the effectiveness of HBV (Honeybee venom) proteins on spike protein RBD by in silico tools. The sequences of 5 HBV proteins were used for homology modeling by Phyre 2. The generated protein models were employed for protein-protein docking against Omicron Spike glycoprotein receptor binding domain (RBD) (PDB ID# 7T9L) through HDock and ClusPro platforms followed by prediction of binding affinity using PRODIGY web portal and PDBsum for revealing interaction details. It was found that all of the examined HBV proteins exhibited strong docking scores and binding affinity profiles toward RBD. The findings of the present study indicate the possible HBV as preventive as well as treatment options against Omicron SARS-CoV-2.

In the early 1980-s, Aaron Ciechanover, Avram Hershko, and Irwin Rose discovered one of the most important cyclic cellular processes – a regulated ATP-dependent protein degradation, for which they were awarded the 2004 Nobel Prize in Chemistry. These scientists proved the existence of a non-lysosomal proteolysis pathway and completely changed the perception of intracellular protein degradation mechanisms. They demonstrated pre-labelling of a doomed protein in a cell with a biochemical marker called ubiquitin. Polyubiquitylation of a protein as a signal for its proteolysis was a new mechanism discovered as a result of collaborative efforts of three scientists on isolation of enzymes involved in this sequential process, clarification of the biochemical stages, and substantiating the energy dependence mechanism. The article contains biographical data of the Nobel laureates, the methods applied, and the history of the research resulted in the discovery of the phenomenon of proteasomal degradation of ubiquitin-mediated proteins.

Toxocariasis is common among children and causes digestive diseases. The aim of the work was to study the development of toxocariasis in children with digestive diseases. The serum levels of specific IgG to Toxocara canis and Ascaris, levels of IL-4 and TNF-α were determined in 63 children. In addition, tests for parasites and a retrospective survey in order to assess sanitation and hygiene practices were conducted. All children were divided into two groups: group I includes 19 (30.2%) patients seropositive for toxocariasis, and group II – 44 (69.8%) children without any parasites. The level of IL-4 was higher in group I (18.0 ± 6.4 pg/ml) than in group II (7.2 ± 2.0 pg/ml) (P < 0.001. While the level of TNF-α did not differ significantly between groups I (4.5 ± 2.1 pg/ml) and II (3.6 ± 1.1 pg/ml) (P > 0.05). A higher incidence of Toxocara was observed among rural residents (78.9%). Children with toxocariasis more often had soil-pica (42.1%), played with dogs (100%), and did not wash their hands (84.2%) compared to the group of uninfected children. It was noted that hygienic habits and place of living contribute to Toxocara canis infection. IL-4 levels were considerably higher in group I than in group II that can be accounted for the host immune response activation, at the same time, the levels of TNF-α did not differ. Children without toxocariasis had also increased levels of IL-4, which may be related to past helminthic infection.

Nitrate pollution of groundwater has been increasing in recent years. The aim of this work was to study the morphological features of the bone marrow of rats at the consumption of drinking water with varying nitrate content. The experiment was performed on 2 groups of white female rats of different ages (mature and immature) with 30 individuals each. Both groups were divided into 5 subgroups that differed in the quality of drinking water consumed by rats on their own. In the 30 days study, nitrate was given to rats in drinking water in doses of 50, 150, 250, 500 mg of sodium nitrate per liter. Animals of the control group drank water from the city water supply. The effect of nitrates on the bone marrow of rats was evaluated by morphological analysis. It was found that the consumption of drinking water with nitrates affected erythropoiesis and leukopoiesis, as evidenced by the growth of blasts, lymphocytes, pronormocytes and normocytes, megakaryocytes and eosinophils, displacement of erythrocyte sprout cells. An increase in the neutrophil maturation index indicates delayed neutrophil maturation, increased yield of mature cells from the bone marrow and depletion of the granulocyte lineage. The more pronounced changes were observed in the qualitative and quantitative composition of the components of the erythrocyte sprout. These disorders were dose-dependent with increasing hematotoxic effect of nitrates at doses of 250 and 500 mg/l in the group of immature animals and resulted in changes in the bone marrow, which may further cause the development of pathological processes in an organism.

The aim of the study was to evaluate changes in the activity of acid and alkaline phosphatases, calcium and phosphorus levels in rats with different courses of experimental gingivitis upon treatment with anti-inflammatory gel with Neovitin and peptide complexes. The experiment was conducted on 100 white nonlinear male rats aged 5-6 months divided into 10 groups: 1 control and 9 – with different courseі of gingivitis. The activity of alkaline and acid phosphatase (ALP, ACP), the levels of calcium (Ca) and phosphorus (P) in rat blood serum and gingiva supernatant were determined. It was found that upon gingivitis, the activity of ALP in blood serum decreased and in gingiva supernatant increased in all groups of animals compared to the control group. The activity of ACP in the serum decreased in hypoergic and hyperergic animal groups and increased in normergia, and in gingiva supernatant increased in all groups: by 2 times in normoergic and hypoergic animals and by 1.4 times in hyperergic. The treatment with anti-inflammatory gel normalized the activity of ALP in both serum and supernatant and decreased the ACP activity in the serum of animals in hypo- and hyperergic groups. The content of serum Ca increased in all groups, and in the supernatant of the gingiva even exceeded the control value. The content of phosphorus in the supernatant of periodontal tissues decreased. The development of the inflammatory process in the periodontium of rats with gingivitis was accompanied by changes in the activity of ACP, ALP, the content of Ca and P in the blood serum and gingival supernatant. The treatment with gel containing neovitin and peptide complexes had a more pronounced therapeutic effect in rats with unchanged reactivity of the organism.
