Dance with me? Analyzing interpersonal synchrony and quality of interaction during joint dance.

This methodological paper examines the assessment of interpersonal synchrony during a joint dancing task between mothers and their children (aged 4 to 5 years) using OpenPose. This pose estimation tool captures movement in naturalistic settings. The study analyzes 45 mother-child dyads, comparing two analytical methods for assessing synchrony, and examines their correlation with the Coding Interactive Behavior (CIB) measure of interaction quality.

[Oil degradation by basidiomycetes in soil and peat at low temperatures].

A total of 17 basidiomycete strains causing white rot and growing on oil-contaminated substrates have been screened. Three strains with high (Steccherinum murashkinskyi), average (Trametes maxima), and low (Pleurotus ostreatus) capacities for the colonization of oil-contaminated substrates have been selected. The potential for degrading crude oil hydrocarbons has been assessed with the use of fungi grown on nonsterile soil and peat at low temperatures.

[Degradation of fluorene and fluoranthene by the basidiomycete Pleurotus ostreatus].

The dependence of the degree of fluorene and fluoranthene degradation by the fungus Pleurotus ostreatus D1 on the culture medium composition has been studied. Polycyclic aromatic hydrocarbons (PAHs) have been transformed in Kirk’s medium (under conditions of laccase production) with the formation of a quinone metabolite and 9-fluorenone upon the use of fluoranthene and fluorene as substrates, respectively. More complete degradation with the formation of an intermediate metabolite, phthalic acid that has undergone subsequent utilization, has occurred in basidiomycete-rich medium (under the production of both laccase and versatile peroxidase).

An Aryl Hydrocarbon Receptor-Mediated Amplification Loop That Enforces Cell Migration in ER-/PR-/Her2- Human Breast Cancer Cells.

The endogenous ligand-activated aryl hydrocarbon receptor (AHR) plays an important role in numerous biologic processes. As the known number of AHR-mediated processes grows, so too does the importance of determining what endogenous AHR ligands are produced, how their production is regulated, and what biologic consequences ensue. Consequently, our studies were designed primarily to determine whether ER/PR/Her2 breast cancer cells have the potential to produce endogenous AHR ligands and, if so, how production of these ligands is controlled.

[Preparation of protoplasts of the fungus Trametes hirsuta 072 and study of the effect of antioxidants on their formation and regeneration].

The consistent application of homogenization and enzymatic treatment is required to obtain protoplasts from the basidiomycete fungus Trametes hirsuta. The maximum yield of protoplasts (∼2.5 × 107/mL) was achieved when mycelium in the exponential growth phase (60 h) was used.

A standard draft genome sequence of the white rot saprotrophic fungus Trametes hirsuta 072 (Basidiomycota, Polyporales) is presented. The genome sequence contains about 33.6 Mb assembled in 141 scaffolds with a G+C content of ~57.

[Transformation of humic substances of highly oxidized brown coal by the basidiomycetes fungi Trametes hirsuta and Trametes maxima].

The ability of the white rot basidiomycetes Trametes hirsuta and Trametes maxima to transform coal humic substances (HS's) under the conditions of solid phase cultivation in the presence or absence of an easily available source of corbon (glucose) has been studied. It was shown that during the growth of the fungal strains used in media, containing HS's, destructive and condensation processes of HS transformation proceeded simultaneously. Based on a comparative physicochemical analysis of the initial HS's and HS's transformed by the fungi, it was established that, despite the introduction of glucose may favor a deeper transformation of HS's by basidiomycetes, the general direction of their modification is dominant reduction or oxidation and is determined by the physiological biochemical peculiarities of the strain used.

Induction of cardiac fibroblast lysyl oxidase by TGF-β1 requires PI3K/Akt, Smad3, and MAPK signaling.

Lysyl oxidase (LOX) is a key extracellular enzyme responsible for the post-translational modification of collagens I and III to form mature fibrillar collagen. Increased expression of LOX is associated with fibrosis and cardiac dysfunction, yet little is known about the regulation of LOX in the heart. In this study, the cell signaling pathways responsible for the regulation of LOX expression by transforming growth factor (TGF)-β1 were assessed.

[Antioxidant and peroxidase activity of saliva in patients with inflammatory periodontal diseases and ability of their correction].

Comparative investigation of antioxidant and peroxidase activities of mixtured saliva during testing loads in control group, as well as in patients with caries and combination of caries with inflammatory periodontal diseases was carried out. Antioxidant activity of saliva in the last two groups was significantly lower, so their correction with xidiphone was made.

[Application of xidiphone in complex of measures for inflammatory periodontal disease prevention].

Investigation of basic biochemical parameters of mixed saliva during sugar and urea tests including application of xidiphone has been carried out. Following parameters--pH, concentration of calcium, inorganic phosphate and fluoride--were measured. It was shown that xidiphone was an universal regulator of acid-base state, calcium-phosphorus an calcium-fluoride homeostasis in oral cavity.

[Comparison of the efficiency of polygalacturonase and beta-glucosidase enzyme preparations in stabilization of cherry plum wine material].

Pektofoetidin and Pectinex, enzyme preparations with the highest polygalacturonase and beta-glucosidase activities, were covalently immobilized on DEAE cellulose and Aminosilochromes 10 and 30. After treatment of cherry plum wine material with the soluble and immobilized enzyme preparations, the content of phenolics increased by 26 and 40%, respectively. The increase was accompanied by a decrease in the protein content (by up to 37%), carbohydrate content (by 17% on the average), and antioxidant activity (5-37%).

The laccases of the basidiomycetes Cerrena unicolor 059, C. unicolor 0784, and Pleurotus oastreatus 0432 were assayed comparatively. The laccases were isolated as homogenous preparations with molecular weight 55, 56, and 57 kD, respectively.

[Fungal decomposition of oat straw during liquid and solid state fermentation].

White rot fungi (Coriolus hirsutus, Coriolus zonatus, and Cerrena maxima from the collection of the Komarov Botanical Institute of the Russian Academy of Sciences) and filamentous fungi (Mycelia sterilia INBI 2-26 and Trichoderma reesei 6/16) were grown on oat straw-based liquid and solid media, as well as in a bench-scale reactor, either individually or as co-cultures. All fungi grew well on solid agar medium supplemented with powdered oat straw as the sole carbon source. Under these conditions, the mould Trichoderma reesei fully suppressed the growth of all basidiomycetes studied; conversely, Mycelia sterilia neither affected the development of any of the cultures, nor did it show any substantial susceptibility to suppression by their presence.

[Regulation of ceruloplasmin activity in oncogynecological diseases].

Serum ceruloplasmih (CP) and anti-CP antibody levels were studied by the oxidase method in 18 healthy women and in 86 women with gynecological tumors.
