Nanostructured Films of Semiconducting Molybdenum Disulfide Obtained Through Exfoliation-Restacking Method
Preparing MoS2 films in mild conditions, using deposition of suspended MoS2 nanoplatelets onto the substrate is described. For this purpose, the nanosized MoS2 particles were obtained via restacking of MoS2 single layers produced by chemical exfoliation of bulk MoS2 crystals in liquid media. X-Ray diffraction study of the films showed that the basal planes of MoS2 crystallites are mainly oriented in the plane paral-lel to the substrate. Atomic force microscopy examination revealed the dependence of the film surface to-pography, as well as the roughness characteristics on the film thickness, which varied in the range of 0.03-2.2 m. Optical absorption spectra of the obtained MoS2 films were found to contain the same absorption bands as the spectra of thin natural MoS2 single crystals. Dark conductivity of the films was determined to be ~ 10β3 SβΡmβ1 at 300 K. The present MoS2 films were found to be photosensitive in the range of 300-800 nm, providing the maximum value of photocurrent under photoexcitation at ~ 440 nm.

Detection of microwave radiation of cytochrome CYP102 A1 solution during the enzyme reaction
Microwave radiation at 3.4β4.2Β GHz frequency of the cytochrome P450 CYP102 A1 (BM3) solution was registered during the lauric acid hydroxylation reaction. The microwave radiation generation was shown to occur following the addition of electron donor NADPH to a system containing an enzyme and a substrate. The radiation occurs for the enzyme solutions with enzyme concentrations of 10β8 and 10β9Β Π. The microwave radiation effect elicited by the aqueous enzyme solution was observed for the first time. The results obtained can be used to elaborate a new approach to enzyme systems research, including studying of the mechanism of interaction of a functioning enzyme system with microenvironment

Materials and Methods: Following primary identification and typing of gut flora composition using microbiological, genetic and metabolomic methods, microbiota substrate pre-sampled from prepared healthy donors was administered to 30 patients with various GIT conditions (pseudomembranous Clostridium colitis, Colitis ulcerosa, Grohn's disease, irritable bowel syndrome, chronic fatigue syndrome). The efficiency of the procedure was determined on the basis of the clinical presentation, lab test results and comparison of microbiota condition prior to transplantation and at least at three points after transplantation - in 2 weeks, 1 and 3 months, using microbiological and metagenomic methods. Study Results: Following one procedure, all patients with antibiotic-associated Clostridium difficile colitis had remission and their normal microflora recovered. Patients with inflammatory GIT conditions had 1 to 2 procedures (depending on the process severity) in addition to their basic therapy, and the positive effect was recorded in all patients (remission, possible drug dose reduction). Conclusion: Faecal transplantation in various pathological GIT conditions demonstrated its perspective and huge therapeutic potential for Colitis ulcerosa, Grohn's disease, C. difficile-associated colitis, functional GIT conditions, metabolic disorders. The efficiency of endoscopic oral transplantation was higher as compared to rectal administration or lyophilized material in capsules.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ: ΠΏΠΎΠΊΠ°Π·Π°ΡΡ ΡΡΡΠ΅ΠΊΡΠΈΠ²Π½ΠΎΡΡΡ ΡΡΠ°Π½ΡΠΏΠ»Π°Π½ΡΠ°ΡΠΈΠΈ ΠΌΠΈΠΊΡΠΎΠ±ΠΈΠΎΡΡ ΠΊΠΈΡΠ΅ΡΠ½ΠΈΠΊΠ° ΠΏΡΠΈ ΡΠ°Π·Π»ΠΈΡΠ½ΡΡ
