The first data on the phylogenetic diversity of planktonic communities of pro- and microeukaryotes in different types of water bodies of the Volga-Don basin during the period of cyanobacterial bloom are presented. Aphanizomenon flos-aquae/Dolichospermum flos-aquae blooms were found mainly in the Kuibyshev Reservoir; Planktothrix agardhii bloom was observed in floodplain lakes of the majority of investigated rivers. Bloom of Raphidiopsis raciborskii was found in a lake on the Volga River terrace, and in a pond in the floodplain of the Samara River Anabaenopsis dominated anong Cyanobacteria. Among heterotrophic prokaryotes, Proteobacteria, Bacteroidota, Verrucomicrobiota, Planctomycetota and Actinobacteriota predominate in the number of sequences, and among protists - Ciliophora, Gyrista (mainly Chrysophyceae), Cryptista and Myzozoa. During the period of cyanobacterial bloom, the contributions of Proteobacteria (especially, Burkholderiales and Pseudomonadales) and Actinobacteriota slightly decrease, while Myzozoa, on the contrary, increase. Monodominant blooms of various species of cyanobacteria significantly change the composition and structure of microbial communities, both at the OTUs and higher taxa levels. The plankton of the pond with Anabaenopsis bloom is most peculiar. Communities with blooms of P. agardhii, R. raciborskii and A. flos-aquae/D. flos-aquae are more similar to each other.

The paper presents reconstruction of the geochemical evolution of the saline lake Shira (South Siberia, Russia) over the past 3000 years based on the elemental composition of bottom sediments. Based on the rock-forming element contents obtained by X-ray fluorescence analysis, the main geochemical indices were calculated to assess the degree of deformation and weathering of the rocks in the catchment basin, paleosalinity, paleoclimate, paleoproductivity and input of clastic materials. Changes in Al2O3 and TiO2 contents reflect the influence of the terrigenous contribution in the lake basin and demonstrate four decreases in the terrigenous removal contribution in the age intervals of 40-135, 580-800, 1900-2020 and 2780-2850 cal. a BP. These intervals are characterized by decreases of Na2O, SiO2, K2O and Fe2O3 contents and increases of MgO and CaO contents. The deceleration in the processes of physical weathering of terrigenous material from banks into the lake and its removal by watercourses is confirmed by the increase of the paleosalinity index and the decrease of chemical weathering. The four considered intervals are characterized by high values of the Ti/Zr ratio, which corresponds to rocks formed close to the provenance area. For the interval 2780-2850 cal. a BP, the change of the Ti/Zr ratio value is not so contrasting in comparison to the intervals 40-135, 580-800 and 1900-2020 cal. a BP. The mineral composition of the bottom sediments of saline lake Shira corresponds to young and immature clay mineral with a high percentage of primary silicate minerals, formed under cold climate conditions.

The results of paleoecological studies of peat deposits in the area of the southeastern part of the Meshchera lowlands (Mostovoye mire) based on the analyses of peat properties, plant macrofossils, charcoal, pollen and radiocarbon dating are presented. The mire was formed in the oxbow depression on the floodplain of the Goose River around 9480 cal. yr. BP and was eutrophic throughout most of the Holocene. Drastic changes in the dynamics of the mire, namely its transition to the mesotrophic stage, characterized by a decrease in the degree of peat decomposition, occurred about 70 years ago. The results of the pollen analysis show the existence of birch-pine forests in combination with shrub thickets formed by Betula nana in the period 9480-8750 cal. yr. BP. In the subsequent stages, the vegetation cover turned to a combination of broad-leaved, birch-pine forests and riverine forests with alder. Frequent fires, both natural and anthropogenic, have favored the development of birch and pine forests over the last millennium.

Despite the long history of studying the conifers dispersal in the Central Kamchatka Depression during the Holocene, the understanding of vegetation dynamics in the northern part of the depression is much weaker due to the lack of palynological sections. Pollen analysis of a peat section located to the southwestern of Shiveluch volcano allowed an assessment of the "Coniferous Island’s" expansion dynamics in the northern part of the Central Kamchatka Depression. According to the data obtained, the expansion of larch forests in this area began about 700 cal. yrs. BP, i.e. 100-150 yrs. later than in the southern part of the depression. Spruce, which replaces larch during succession, began to spread here about 400 cal. yrs. BP, as in the rest of the depression.

One of the promising approaches to the treatment of infections caused by multidrug-resistant bacteria looks a therapy with bacteriophage. While bacteriophages are indifferent to bacterial resistance to antibiotics, bacteriophages are generally strain-specific, i.e., various isolates of the same bacterium can be insensitive to the given phage, that requires the creation of the library of bacteriophages. Here we report the isolation from wastewater from the city of Kazan (Republic of Tatarstan) the number of bacteriophages virulent against a number of opportunistic bacteria (Klebsiella pneumoniae, Escherichia coli, Cronobacter sakazakii and Enterococcus faecalis, Salmonella enterica Enteritidis and Typhimurium). Phages formed a clear plaques on the bacterial lawn and had a titer up to 109 PFU/ml. Additionally, the polyvalent properties of bacteriophages were revealed: KES1, KES2 are lytic against C. sakazakii and S. enterica serovar Enteritidis, KST1 lyses S. enterica serovars Enteritidis and Typhimurium, KEF1 is virulent against E. faecalis and S. enterica serovar Enteritidis.

Published: September 2024

In this study, the effect of Schiff base compound derived from 4-Aminoantipyrine and 1-phenylbutan-1,3-dione and its Ni(II) complex, on the haematology indices of diabetic rats was investigated. A single intraperitoneal injection of Alloxan (120 mg/kg body weight), induced diabetes. The rats were treated with 200 and 400 mg/kg of body weight of 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro-1H-Pyrazol-4-yl)Hydrazinylidene]-1-Phenylbutanedione (HL) and its Ni(II) complex ([Ni(HL)2]Cl2) respectively for 14 days, following which they were humanely sacrificed under chloroform. A heart puncture was used to collect blood, and some of the blood samples were analyzed to evaluate white blood cell (WBC), red blood cell (RBC) counts, packed cell volume (PCV) and hemoglobin (Hb) concentration, and differential blood count profiles. Red blood cells, hemoglobin and packed cell volume concentrations in rats treated with HL and [Ni(HL)2]Cl2 in (low and high doses) increased when compared with untreated group B diabetic rats. The Eosinophils, Monocytes, and Lymphocytes were observed to be bad in the diabetic rats; this was significantly better in the treatment groups. HL and [Ni(HL)2]Cl2 have therapeutic promise as functional medicines against diabetes and complete blood count alterations linked to diabetes mellitus, as demonstrated by these studies. In the diabetic group, oxidative stress results in RBC dysfunction, platelet destruction, and tissue injury. These affect the functions of blood cells and the haemostatic parameters which may lead to various complications. As a result, these substances may be used as medication therapy for diabetes since they lower the glucose concentration without alterations in blood cells.

Collagen II enrichment through scAAV6-RNAi-mediated inhibition of matrix-metalloproteinases 3 and 13 in degenerative nucleus-pulposus cells degenerative disc disease and biological treatment strategies
Authors: Mern Demissew Shenegelegn , Thomé Claudius 
Published: September 2024

Intervertebral disc (IVD) degeneration damaging the extracellular matrix (ECM) of IVDs is the main cause of spine-associated disorders. Degenerative disc disease (DDD) is a multifaceted disorder, where environmental factors, inflammatory cytokines and catabolic enzymes act together. DDD starts typically due to imbalance between ECM biosynthesis and degradation within IVDs, especially through unbalanced degradation of aggrecan and collagen II in nucleus pulposus (NP). Current treatment approaches are primarily based on conservative or surgical therapies, which are insufficient for biological regeneration. The disintegrins and metalloproteinases with thrombospondin motifs (ADAMTSs) and matrix metalloproteinases (MMPs) are the key proteolytic enzymes for degradation of aggrecan and collagens. Previously, high expression levels of ADAMTS4, ADAMTS5, MMP3 and MMP13, which are accompanied with low levels of aggrecan and collagen II, were demonstrated in degenerative human NP cells. Moreover, self-complementary adeno-associated virus type 6 (scAAV6) mediated inhibitions of ADAMTS4 and ADAMTS5 by RNA-interference (RNAi) could specifically enhance aggrecan level. Thus, MMPs are apparently the main degrading enzymes of collagen II in NP. Furthermore, scAAV6-mediated inhibitions of MMP3 and MMP13 have not yet been investigated. Therefore, we attempted to enhance the level of collagen II in degenerative NP cells by scAAV6-RNAi-mediated inhibitions of MMP3 and MMP13. MRI was used to determine preoperative grading of IVD degeneration in patients. After isolation and culturing of NP cells, cells were transduced with scAAV6-shRNAs targeting MMP3 or MMP13; and analysed by fluorescence microscopy, FACS, MTT assay, RT-qPCR, ELISA and western blotting. scAAV6-shRNRs have no impact on cell viability and proliferation, despite high transduction efficiencies (98.6%) and transduction units (1383 TU/Cell). Combined knockdown of MMP3 (92.8%) and MMP13 (90.9%) resulted in highest enhancement of collagen II (143.2%), whereby treatment effects were significant over 56 days (p &lt; 0.001). Conclusively, scAAV6-RNAi-mediated inhibitions of MMP3 and MMP13 help to progress less immunogenic and enduring biological treatments in DDD.
