    Campylobacter jejuni colonizes hosts by interacting with Blood Group Antigens (BgAgs) on the surface of gastrointestinal epithelia. Genetic variations in BgAg expression affects host susceptibility to C. jejuni. Here, we show that the essential major outer membrane protein (MOMP) of C. jejuni NCTC11168 binds to the Lewis b (Leb) antigen on the gastrointestinal epithelia of host tissues and this interaction can be competitively inhibited by ferric quinate (QPLEX), a ferric chelate structurally similar to bacterial siderophores. We provide evidence that QPLEX competitively inhibits the MOMP-Leb interaction. Furthermore, we demonstrate that QPLEX can be used as a feed additive in broiler farming to significantly reduce C. jejuni colonization. Our results indicate that QPLEX can be a viable alternative to the preventative use of antibiotics in broiler farming to combat C. jejuni infections

    Β Prostate cancer (PGC) is leading the way in the structure of cancer morbidity around the world. The presence of prostatic concretions (PC) and skeletal metastases significantly reduces the patients’ life quality and worsens the prognosis of the disease.Aim. The aim of study was to define the impact of PC on the development of prostate cancer bone metastases.Materials and methods. 30 samples of PGC with PC and 30 PGC tissue samples without PC were analyzed by histology (hematoxylin-eosin staining), histochemistry (von Kossa and Alizarin red staining), immunohistochemistry (OSN, Col I, Col II, p53, Bax, Casp3, MPO, CD68). PC were analyzed by SEM-EDS and XRD with different temperature of heat pretreatment.Results. All PC samples had the calcium hydroxyapatite origin with a slight deviation from the stoichiometric composition and admixture of extraneous elements. The presence of zinc oxide and iron-containing calcium phosphate in the structure of PC was found by XRD. We revealed significantly higher expression of Π’Π°Ρ…, Π‘Π°sp3, MPO and CD68 in PGC tissue with PC (P < 0.001). We suggest that the combination of these factors predetermines the development of a specific phenotype of cancer cells which is manifested by the significantly higher OSN and Col I expression in PGC with PC (P < 0.001). It contributes to recognizing of bone tissue as an optimal environment for the growth and development of PGC metastases by cancer cells.Conclusions. The presence of PC in the PGC tissue promotes the development of a specific osteoblastic immunophenotype of cancer cells. It can determine the tropism of PGC metastases to bone tissue.Β Β Π Π°ΠΊ ΠΏΡ€Π΅Π΄ΡΡ‚Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎΠΉ ΠΆΠ΅Π»Π΅Π·Ρ‹ (Π ΠŸΠ–) Π·Π°Π½ΠΈΠΌΠ°Π΅Ρ‚ Π²Π΅Π΄ΡƒΡ‰ΠΈΠ΅ ΠΏΠΎΠ·ΠΈΡ†ΠΈΠΈ Π² структурС онкологичСской заболСваСмости ΠΈ смСртности ΠΌΡƒΠΆΡ‡ΠΈΠ½ ΠΏΠΎ всСму ΠΌΠΈΡ€Ρƒ.

    According to the results of the Euro-Heart Survey on Vascular Heart Disease the most common pathology is nonrheumatic aortic stenosis, it is also called as calcific aortic valve stenosis (CAVS), as in its pathogenesis the process of biomineralization of valve cusps and ring plays the main role. The aim of the work is the immunohistochemical study of mineralized tissue of aortic heart valves, which are affected by atherocalcinosis. Materials and methods. 30 samples of mineralized aortic valves (I group) and 10 samples of aortic valve without evidence of biomineralization (II group - control) were studied. Immunohistochemical study of expression of collagen (Collagen I), CD68, myeloperoxidase (MPO), calgranulin A (S100A8), calgranulin B (8100A9), caspase 3 (Casp 3) and osteopontin (OPN) was conducted in AV tissue of both groups. Results. In CAV tissues the fibrillar component (collagen I) growths was found, but the quantitative and qualitative compositions of CD68+ circulating inflammatory cells are not significantly different from the control group. CAVs contain much more MPO+-cells (p <0.001) in comparison to the group of AVs without biomineralization. Our data show a significant increase of the S100A9 and OPN expression in the mineralized tissue of AVs (p <0.01). Also, a higher expression level of Casp3 and MPO was found in CAVs (p <0.05). Comparing the first and the second groups of AVs connection between the expression of S100A8 was not determined. Conclusion. High Casp 3 expression confirms the increased level of cell elimination in the CAVs tissue, which is obviously connected with the impact of high local concentrations of S100A9. These facts can contribute to the development of pathological biomineralization of AV. Since osteopontin inhibits the hydroxyapatite formation by binding to the surface of the crystals, its hyperproduction is a counteracting factor against biomineralization in AV tissue

    The paper discusses the technology of obtaining organic and organo-mineral granules of prolonged action. It is found that the granular marketable product must meet certain requirements for particle size. Consequently, the separation unit (classification) in the developed technological scheme plays a very important role in the process of obtaining commodity pellets. The object of research is the process of classification of granular organic fertilizers in the rhombic gravitational pneumatic classifier. The study is aimed at establishing the optimal mode-technological parameters of the Β«rhombicΒ» pneumatic classifier. For this, a physical model of the process of pneumatic classification of dispersed particles (granules) in a rhombic form is studied, which explains the conditions for the separation of a polydisperse mixture into narrower fractions, the formation of a suspended layer of material. As well as a cyclic mechanism for loading and unloading the suspended layer. In addition to ensuring the purity of the product, the apparatus should also have a low hydraulic resistance and low power consumption. For physical modeling, a laboratory bench of a rhombic gravitational pneumatic classifier is used, on which a number of experiments are performed on the selection of the optimal separation mode and product purity. Rational use of the working space and effective ways to influence the flow of material within the same building allows to obtain the required separation parameters. Carrying out the classification process in the Β«rhombicΒ» pneumatic classifier can effectively remove up to 99 % of particles less than 2 mm in size from the granulated product. At the exit of the apparatus, let's obtain a marketable product with a particle size of 2–4 mm in an amount of 99 %, which corresponds to the standard requirements for a qualitative particle size distribution. Such an effective separation in this apparatus is due to its shape (optimal opening angles and closure of the Β«rhombΒ» of the case), which contributes to the rotation of the material flow and leads to an additional reseeding. The absence of contact elements inside the device significantly reduces its hydraulic resistance and reduces energy consumption

    Helicobacter pylori attachment-blocking antibodies protect against duodenal ulcer disease

    : The majority of the world population carry the gastric pathogen Helicobacter pylori. Fortunately, most individuals experience only low-grade or no symptoms, but in many cases the chronic inflammatory infection develops into severe gastric disease, including duodenal ulcer disease and gastric cancer. Here we report on a protective mechanism where H. pylori attachment and accompanying chronic mucosal inflammation can be reduced by antibodies that are present in a vast majority of H. pylori carriers. These antibodies block binding of the H. pylori attachment protein BabA by mimicking BabA's binding to the ABO blood group glycans in the gastric mucosa. However, many individuals demonstrate low titers of BabA blocking antibodies, which is associated with an increased risk for duodenal ulceration, suggesting a role for these antibodies in preventing gastric disease
