In this work data on heterogeneity in halotolerance and the resistance to antibiotics of heterotrophic bacteria dominating in Lake Shira (Republic of Khakasia, Russia) were presented. It was established that halotoler-ance of the bacteria is determined by genetic and epigenetic mechanisms. Influence of anthropogenic factor (entering the ecosystem allochthonous bacteria) on the appearance of multiple antibiotic resistance appear-ance by dominating bacterial species is discussed.

With increasing life expectancy， neurodegenerativ. diseases hav. become one of the leading causes of ill-health in the elderly. Prev.ntiv. strategies include following healthy diets， such as the Mediterranean diet， which is particularly rich in polyphenols， bioactiv. compounds with neuroprotectiv. properties. The aim of this study was to assess the association of microbial phenolic metabolites (MPM) with cognition. This cross-sectional analysis was performed with 200 participants of the PREDIMED trial (Barcelona-Clinic recruitment center). A nov.l method based on liquid chromatography coupled to mass spectrometry was used to identify urinary MPM (protocatechuic acid， enterodiol glucuronide， enterolactone glucuronide， urolithin B glucuronide， and v.nillic acid glucuronide)， and cognitiv. function was ev.luated with neuropsychological tests. Multiv.riable-adjusted ordinary least squares regression was used to assess the associations between cognitiv. function and MPM， and a score was calculated as the weighted sum of MPM. A higher MPM score was associated with better frontal lobe function. Among indiv.dual metabolites， v.nillic acid glucuronide was correlated with frontal cognitiv. performance. Participants with higher concentrations of v.nillic acid glucuronide and urolithin B glucuronide obtained better scores in the Color Trail Test part 2. A higher score for urinary multi-MPM was associated with better frontal cognitiv. performance in an older Mediterranean population.

Cu/ZrO2/SiO2 are efficient catalysts for the selectiv. hydrogenation of CO2 to CH3OH. In order to understand the role of ZrO2 in these mixed-oxides based catalysts, in situ X-ray absorption spectroscopy has been carried out on the Cu and Zr K-edge. Under reaction conditions, Cu remains metallic, while Zr is present in three types of coordination env.ronment associated with 1) bulk ZrO2, 2) coordinativ.ly saturated and 3) unsaturated Zr(Ⅳ) surface sites. The amount of coordinativ.ly unsaturated Zr surface sites can be quantified by linear combination fit of reference X-Ray absorption near edge structure (XANES) spectra and its amount correlates with CH3OH formation rates, thus indicating the importance of Zr(Ⅳ) Lewis acid surface sites in driv.ng the selectiv.ty toward CH3OH. This finding is consistent with the proposed mechanism, where CO2 is hydrogenated at the interface between the Cu nanoparticles that split H2 and Zr(Ⅳ) surface sites that stabilizes reaction intermediates.

Heat stress affects epigenetic gene silencing in Arabidopsis. To test for a mechanistic inv.lv.ment of epige-netic regulation in heat-stress responses, we analyzed the heat tolerance of mutants defectiv. in DNA methylation, his-tone modifications, chromatin-remodeling, or siRNA-based silencing pathways. Plants deficient in NRPD2, the common second-largest subunit of RNA polymerases Iv.and v. and in the Rpd3-type histone deacetylase HDA6 were hypersensi- tiv. to heat exposure. Microarray analysis demonstrated that NRPD2 and HDA6 hav. independent roles in transcriptional reprogramming in response to temperature stress. The misexpression of protein-coding genes in nrpd2 mutants recov.r-ing from heat correlated with defectiv. epigenetic regulation of adjacent transposon remnants which inv.lv.d the loss of control of heat-stress-induced read-through transcription. We prov.de ev.dence that the transcriptional response to temperature stress, at least partially, relies on the integrity of the RNA-dependent DNA methylation pathway.
