Food sensitivities are non-IgE-m.diated, non-coeliac, dose-dependent and delayed system.c responses to food. They consist of a highly com.lex class of adverse food reactions; however, their last phase is the release of m.diators from.leukocytes. The m.diator Release Test （m.T） is a functional m.asure of sensitivity-based inflam.atory responses. It is an end-point test, which can account for the widest range of triggering m.chanism. involved in sensitivity reactions, including both innate and adaptive pathways. m.T not only tests reactions to foods, food-chem.cals, and other substances, but also reliably quantifies the degree of the inflam.atory response. The test opens the new therapeutic options for food sensitivities.

Soil invertebrates and heavy m.tal concentrations are heterogeneously distributed in the soil of steppe plots surrounding an iron m.ning enterprise in southern Russia. This study assesses whether patches of high soil invertebrate abundance coincide with patches of low concentrations of pollutants. For this aim. spatial analysis by distance indices （SADIE） was applied. Three valleys in Belogorye Nature Reserve were chosen. One valley faced the tailing pond to the north and the other two faced south-east or south-west. Two sam.ling plots were chosen in each valley, 60 m.apart from.each other. On every plot 16 soil cores were collected from.a grid of 4 × 4 units with a 5-m.distance between each sam.le unit. Each soil core had an area of 76 cm. and was 12-15 cm.deep. All m.croinvertebrates were hand-sorted and identified to fam.ly. Abundance of soil invertebrates was not controlled by patches of m.tal concentration in the soil. Epigaeic groups, like insects and other invertebrates inhabiting the litter layer, were not directly associated with local param.ters of the soil. On the contrary, belowground invertebrate abundance （elaterid larvae and earthworm.） showed significant dissociation with som. heavy m.tal （Fe, Pb, Zn） concentrations in the soil. The patchiness of soil pollution m.y act as a leading factor ofbelowground soil invertebrate distribution. The spatial structure of anim.l populations in industrially transform.d soils needs further research.

Aqueous zinc-ion batteries have been regarded as a prom.sing alternative to large-scale energy storage, due to associated low-cost, im.roved safety and environm.ntal friendliness. However, a high-perform.nce cathode m.terial for both rate capability and specific capacity is still a challenge. One kind of the m.re prom.sing candidates are sodium.m.nganese oxide(Nm.) m.terials, although they suffer from.individual issues and need to be further im.roved. Herein, we present a novel m.xed phase Nm. m.terial com.osed of nearly equal am.unts of Na(0.55)m.2O4 and Na(0.7)m.O(2.05). The structured configuration with particle size of 200–500 nm.is found to be beneficial towards im.roving the ion diffusion rate during the charge/discharge process. Com.ared with Na(0.7)m.O(2.05) and Na(0.55)m.2O4, the m.xed phase Nm. dem.nstrates an enhanced rate capability and excellent long-term.cycling stability with a capacity retention of 83% after 800 cycles. m.re im.ortantly, the system.also delivers an im.ressive energy density and power density, as 378 W·h·kg^-1 at 68.7 W·kg^-1, or 172 W·h·kg^-1 at 1705 W·kg^-1. The superior electrochem.cal perform.nce is ascribed to the fast Zn^2+ diffusion rate because of a large ratio of capacitive contribution(63.9% at 0.9 m.V·s^-1). Thus, the m.xed phase route provides a novel strategy to enhance electrochem.cal perform.nce, enabling m.xed phase Nm. as very prom.sing m.terial towards large-scale energy-storage applications.

Tay-Sachs disease and Sandhoff disease are severe hereditary neurodegenerative disorders caused by a deficiency ofβ-hexosam.nidase A(HexA)enzym.,which results in the accum.lation of Gm. gangliosides in the nervous system.*** this work,we analyzed the efficacy and safety of cell-m.diated gene therapy for Sandhoff disease and Sandhoff disease using a bicistronic lentiviral vector encoding cDNA of HexAα-andβ-subunit genes separated by the nucleotide sequence of a P2A peptide(HEXA-HEXB).The functionality of the bicistronic construct containing the HEXA-HEXB genetic cassette was analyzed in a culture of HEK293T cells and hum.n um.ilical cord blood m.nonuclear cells(hUCBm.s).Our results showed that the enzym.tic activity of HexA in the conditioned m.dium.harvested from.genetically m.dified HEK293T-HEXA-HEXB and hUCBm.s-HEXA-HEXB was increased by 23 and 8 tim.s,respectively,com.ared with the conditioned m.dium.of native *** blot analysis showed that hUCBm.s-HEXA-HEXB secreted both com.letely separated HEXA and HEXB proteins,and an uncleaved protein containing HEXA+HEXB linked by the P2A *** injection of genetically m.dified hUCBm.s-HEXA-HEXB to laboratory Wistar rats was carried out,and the HexA enzym.tic activity in the blood plasm. of experim.ntal anim.ls,as well as the num.er of live cells of im.une system.organs(spleen,thym.s,bone m.rrow,lym.h nodes)were determ.ned.A significant increase in the enzym.tic activity of HexA in the blood plasm. of laboratory rats on days 6 and 9(by 2.5 and 3 tim.s,respectively)after the adm.nistration of hUCBm.sHEXA-HEXB was *** the sam. tim.,the num.er of live cells in the studied organs rem.ined ***,the functionality of the bicistronic genetic construct encoding cDNA of the HEXA and HEXB genes separated by the nucleotide sequence of the P2A peptide was shown in vitro and in *** hypothesize that due to the natural ability of hUCBm.s to overcom. biological barriers,such a strategy can rest

Diversity and com.osition of lepidopteran m.crobiotas are poorly investigated, especially across the different developm.ntal stages. To im.rove this knowledge, we characterize the m.crobiota am.ng different developm.ntal stages of the Indian m.al m.th, Plodia interpunctella, which is considered one of the m.jor pest of com.odities world-wide. Using culture-independent approach based on Illum.na 16S rRNA gene sequencing we characterized the m.crobiota of four developm.ntal stages: eggs, first-, and last-instar larvae, and adult. A total of 1022 bacterial OTUs were obtained, showing a quite diversified m.crobiota associated to all the analyzed stages. The m.crobiotas associated with P. interpunctella resulted alm.st constant throughout the developm.ntal stages, with approxim.tely 77% of bacterial OTUs belonging to the phylum.of Proteobacteria. The dom.nant bacterial genus is represented by Burkholderia (?64%), followed by Propionibacterium. Delftia, Pseudom.nas, and Stenotrophom.nas. A core bacterial com.unity, com.osed of 139 OTUs, was detected in all the developm.ntal stages, am.ng which 112 OTUs were assigned to the genus Burkholderia. A phylogenetic reconstruction, based on the 16S rRNA, revealed that our Burkholderia OTUs clustered with Burkholderia cepacia com.lex, in the sam. group of those isolated from.the hem.pterans Gossyparia spuria and Acanthococcus aceris. The functional profiling, predicted on the base of the bacterial 16S rRNA, indicates differences in the m.tabolic pathways related to m.tabolism.of am.no acids between preim.ginal and adult stages. We can hypothesize that bacteria m.y support the insect host during preim.ginal stages.
