    The aim of the study was to investigate morphological traits of hepatic parenchymal tissue repair in response to injury using the conventional technique (closure) and an innovation method (such as hemostatic medication swab packing and modified batching). The experimental study was carried out on laboratory rats of the Winzar breed using light microscopy, standard stains for micropreparations, and morphometry. Histopathologic examination of micropreparations stained by standard methods revealed pronounced dystrophic processes in hepatocytes located near the necrotic zone (albuminous and hydropic degeneration and chromatin fragmentation in the nuclei). Morphometric studies showed a significant decrease (p<0.001) in almost all indicators of the size of cells and nuclei both near necrosis and distant from it on day 28 of the experiment in the experimental group in comparison to the control group. The results obtained pointed to more intense repair processes when applying the innovation method.Cilj istraΕΎivanja bio je ispitati morfoloΕ‘ke značajke oporavka parenhimnog tkiva jetre u odgovoru na oΕ‘teΔ‡enje primjenom konvencionalne tehnike (zatvaranje) i inovacijske metode (kao Ε‘to je oblaganje gazom natopljenom hemostatskim lijekom i modificiran batching). Ovo eksperimentalno istraΕΎivanje provedeno je na laboratorijskim Winzar Ε‘takorima primjenom svjetlosne mikroskopije, standardnih boja za mikropreparate i morfometrije. HistopatoloΕ‘ka analiza mikropreparata obojenih standardnim metodama pokazala je znatne distrofične procese u hepatocitima blizu nekrotične zone (albuminozna i hidropična degeneracija, fragmentacija kromatina u jezgrama). Morformetrijska ispitivanja pokazala su značajno smanjenje (p<0,001) svih pokazatelja veličine stanica i jezgara kako blizu nekroze tako i dalje od nje 28. dana eksperimenta u eksperimentalnoj skupini u usporedbi s kontrolnom skupinom. Dobiveni rezultati ukazuju na intenzivnije procese oporavka kad je primijenjena inovacijska metoda

    Cervical and Endometrial Cancer Incidence in the Female Population from the Bryansk Region Living in Conditions of Chemical, Radioactive and Combined Environmental Contamination (2000&ndash;2020)

    No full text
    At the end of 36 years after the Chernobyl disaster, about 5 million people still live in the radioactively contaminated territories of Russia, Ukraine, and Belarus, and the density of radioactive contamination by Cesium-137 and Strontium-90 will remain radiologically significant for decades. We assessed cervical and endometrial cancer primary incidence (new cases) in the female population from the Bryansk region living in conditions of chemical, radioactive, and combined environmental contamination for 2000&ndash;2020. We found a significant increase in the long-term trend in the primary incidence of cervical and endometrial cancer in all the studied groups, regardless of the environmental conditions of residence (p &lt; 0.00001). We did not find statistically significant differences in the incidence of cervical and endometrial cancer in women, regardless of the level of chemical, radioactive, and combined environmental contamination. However, women living in environmentally unfavorable areas (in total, in the territories of chemical, radioactive, and combined contamination) are statistically significantly more likely to develop endometrial cancer in terms of relative risk compared to environmentally safe (control) areas (RR 1.17 (1.08&ndash;1.27)). No such pattern was found for cervix cancer. It should be noted, since environmentally safe (control) areas have a certain level of contamination (albeit low), RR is underestimated

    1,2,4-Oxadiazole/2-Imidazoline Hybrids: Multi-target-directed Compounds for the Treatment of Infectious Diseases and Cancer

    No full text
    Replacement of amide moiety with the 1,2,4-oxadiazole core in the scaffold of recently reported efflux pump inhibitors afforded a novel series of oxadiazole/2-imidazoline hybrids. The latter compounds exhibited promising antibacterial activity on both Gram-positive (Staphylococcus aureus, Bacillus subtilis) and Gram-negative (Escherichia coli, Pseudomonas fluorescens) strains. Furthermore, selected compounds markedly inhibited the growth of certain drug-resistant bacteria. Additionally, the study revealed the antiproliferative activity of several antibacterial frontrunners against pancreas ductal adenocarcinoma (PANC-1) cell line, as well as their type-selective monoamine oxidase (MAO) inhibitory profile

    Monoamine oxidase inhibition properties of 2,1‑benzisoxazole derivatives

    No full text
    onoamine oxidase (MAO) are favoenzymes that metabolize neurotransmitter, dietary and xenobiotic amines to their corre sponding aldehydes with the production of hydrogen peroxide. Two isoforms, MAO-A and MAO-B, are expressed in humans and mammals, and display diferent substrate and inhibitor specifcities as well as diferent physiological roles. MAO inhibi tors are of much therapeutic value and are used for the treatment of neuropsychiatric and neurodegenerative disorders such as depression, anxiety disorders, and Parkinson’s disease. To discover MAO inhibitors with good potencies and interesting isoform specifcities, the present study synthesized a series of 2,1-benzisoxazole (anthranil) derivatives and evaluated them as in vitro inhibitors of human MAO. The compounds were in most instances specifc inhibitors of MAO-B with the most potent MAO-B inhibition observed for 7a (IC50=0.017 Β΅M) and 7b (IC50=0.098 Β΅M). The most potent MAO-A inhibition was observed for 3l (IC50=5.35 Β΅M) and 5 (IC50=3.29 Β΅M). It is interesting to note that 3-(2-aminoethoxy)-1,2-benzisoxazole derivatives, the 1,2-benzisoxazole, zonisamide, as well as the isoxazole compound, lefunomide, have been described as MAO inhibitors. This is however the frst report of MAO inhibition by derivatives of the 2,1-benzisoxazole structural isome

    Copper-Catalyzed Selective Arylation of Oxadiazolones by Diaryliodonium Salts

    No full text
    The direct N-arylation of cyclic amides can be considered a pivotal issue for modern organic chemistry. Here, we report the method for copper-catalyzed N-arylation of diverse oxadiazolones by diaryliodonium salts in mild conditions in high yields (up to 92%) using available CuI as a catalyst. The developed method allows to efficiently utilize both symmetric and unsymmetric diaryliodonium salts bearing auxiliary groups such as 2,4,6-trimethoxyphenyl (TMP). The evaluation of steric effects in aryl moieties to the chemoselectivity of N- and O-arylation of the 1,2,4-oxadiazol-5(4H)-ones exhibited the high potential of mesityl-substituted diaryliodonium salts as a selective arylation reagent. The structural study suggests that steric accessibility of N-atom in 1,2,4-oxadiazol-5(4H)-ones impact to arylation with sterically hindered diaryliodonium salts. The synthetic application of proposed method was also demonstrated on selective arylation of 1,3,4-oxadiazol-2(3H)-ones and 1,2,4-oxadiazole-5-thiol
