Specific Features of the Proteomic Response of Thermophilic Bacterium to Terahertz Irradiation.

Studying the effects of terahertz (THz) radiation on the proteome of temperature-sensitive organisms is limited by a number of significant technical difficulties, one of which is maintaining an optimal temperature range to avoid thermal shock as much as possible. In the case of extremophilic species with an increased temperature tolerance, it is easier to isolate the effects of THz radiation directly. We studied the proteomic response to terahertz radiation of the thermophilic , persisting under wide temperature fluctuations with a 60 °C optimum.

Heterologous Expression of Extracellular Proteinase pAsPs of in .

Neutral protease pAsPs gene was obtained by sequence optimization of NpI protease from pAsPs was for the first time integrated in the genome of yeast strain T07, and then produced in a 5 L bioreactor with an enzyme yield of 150,800 U/mL of culture liquid towards casein. The specific activity of the pAsPs was 7,657,000 U/mg toward casein, 2320 U/mg toward hemoglobin, and 25,344 U/mg toward azocasein per 1 mg of the protein. The enzyme was found to be inhibited by Cu.

Heterologous Expression of Xylanase xAor from Aspergillus oryzae in Komagataella phaffii T07.

Xylanases (EC 3.2.1.

Fluorescent bacterial biosensor /pTdcR-TurboYFP sensitive to terahertz radiation.

A fluorescent biosensor /pTdcR-TurboYFP sensitive to terahertz (THz) radiation was developed via transformation of () cells with plasmid, in which the promotor of the gene controls the expression of yellow fluorescent protein TurboYFP. The biosensor was exposed to THz radiation in various vessels and nutrient media. The threshold and dynamics of fluorescence were found to depend on irradiation conditions.

[REAL TIME POLYMERASE CHAIN REACTION IN TULAREMIA LABORATORY DIAGNOSTICS].

Aim: Enhancement of tularemia laboratory diagnostics by F. tularensis DNA determination in blood sera of patients using real time polymerase chain reaction (RT-PCR).

Materials And Methods: 39 blood sera of patients obtained during transmissive epidemic outbreak of tularemia in Khanty-Mansiysk in 2013 were studied in agglutination reaction, passive hemagglutination, RT-PCR.

[Epizootic and epidemic manifestation of natural foci of tularemia in Moscow region (1965-2013)].

Aim: Detection of contemporary features of tularemia focimanifestations, determination of territories of high epidemic risk in various landscape zones and creation of a map of foci territories of Moscow Region for isolation of tularemia infectious agent cultures and registered human morbidity for justified planning of prophylaxis measures.

Materials And Methods: Report materials of epizootologic examinations of natural foci for 1965-2013, 156 maps of epidemiologic examination of cases of human infection with tularemia, results of studies of casting of predatory birds and dung of predatory mammals were used. Registered morbidity and isolation of tularemia infectious agent cultures from 1965 to date were applied to an electronic map of Moscow Region by sign method using modern.

Oxidation by oxygen and sulfur of Tin(IV) derivatives containing a redox-active o-amidophenolate ligand.

Oxidation of tin(IV) o-amidophenolate complexes [Sn(ap)Ph(2)] (1) and [Sn(ap)Et(2)(thf)] (2) (ap=dianion of 4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-iminobenzoquinone (ImQ)) with molecular oxygen and sulfur in toluene solutions was investigated. The reaction of oxygen with 1 at room temperature forms a paramagnetic derivative [Sn(isq)(2)Ph(2)] (3) (isq=radical anion of ImQ) and diphenyltin(IV) oxide [{Ph(2)SnO}(n)]. Interaction of 1 with sulfur gives another monophenyl-substituted paramagnetic tin(IV) complex, [Sn(ap)(isq)Ph] (4), and the sulfide, [Ph(3)Sn](2)S.
