MorfoloΕ‘ke znaΔajke oporavka jetrenog parenhima nakon eksperimentalno izazvanog oΕ‘teΔenja
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 znaΔajke oporavka parenhimnog tkiva jetre u odgovoru na oΕ‘teΔenje 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 distrofiΔne procese u hepatocitima blizu nekrotiΔne zone (albuminozna i hidropiΔna
degeneracija, fragmentacija kromatina u jezgrama). Morformetrijska ispitivanja pokazala su znaΔajno smanjenje
(p<0,001) svih pokazatelja veliΔine 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

Automated Testing of Information Security Devices, Which Represented as Removable Media, and its Issues
This article describesissues, arising in automatedtesting of information security devices, which represented as removable media. These devices have their own operational system, whichimposes restrictions on its testing process. This paper proposes several new methods for automated testing of such devices
Cervical and Endometrial Cancer Incidence in the Female Population from the Bryansk Region Living in Conditions of Chemical, Radioactive and Combined Environmental Contamination (2000–2020)
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 2000–2020. 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 < 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 (1.08–1.27)). 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
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 2,1βbenzisoxazole derivatives
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 Parkinsonβs 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
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
