The Covid-19 pandemic and ongoing war in Ukraine caused unprecedented disruption in healthcare, including cytopathology activities. This paper elucidates the effect of two consecutive disasters-the COVID-19 pandemic followed by the war-on cytopathology practice in Ukraine through a single-centre retrospective study. Total testing volumes, geographic distribution, and indicators of laboratory operations were assessed during three periods of 3 months each: the first 3 months of the acute phase of the war (March-May 2022, period 1); summer (June-August 2022, period 2); and the fall (September-November 2022, period 3, associated with massive attacks on the energy infrastructure in Ukraine).

The application of pristine С fullerene aqueous colloid solution (CFAS; 0.5 mg/kg body weight) for rats experienced acute colitis, either intraperitoneally or intrarectally (1) restores the colonic mucosa healing and epithelial barrier integrity, evidenced by autopsies and histological findings and the normalization of phenolsufonphthalein dye daily excretion; (2) attenuates the consequences of hemorrhages, such as signs of anemia and increased platelet count; (3) improves the liver redox status suppressing the lipid peroxidation (malonic dialdehyde and protein carbonyl group levels tended down) and stimulating the antioxidant defense system (glutathione peroxidase activity grew up). In addition, CFAS intrarectally increases the monocyte count and decreases content of neutrophil granulocytes, i.

Morphofunctional parameters of blood cells of the rats with dimethylhydrazine induced colon carcinogenesis have been investigated. The reduction of Mean corpuscular hemoglobin (MCH) and Mean corpuscular hemoglobin concentration (MCHC) whereas increasing of reticulocytes number and indirect bilirubin after 20 weeks of experiment of dimethylhydrazine (DMH)-induced colon carcinogenesis indicate the hemolysis of red blood cells due to the DMH influence during tumors development. The moderate increasing of monocytes and platelets number, as well as increment of eosinophilic granulocytes number have been observed.

The effect of the protein kinase inhibitor maleimide derivative (MI-, 1, 1-(4-Cl-benzyl)-3-CI-4-(CF3-phenylamino)- 1H-pyrrole-2,5-dione) on blood cells of rats with 1,2-dimethylhydrazine (DMH)-induced colon carcinogenesis has been studied. Administration of MI-I1 at 2.7 mg/kg for 20 weeks on DMH-induced carcinogenesis prevents anemia, which is a consequence of cancer and complicates it.

In vitro antifungal activity of phenylheptatriyne from Bidens cernua L. (Asteraceae) was studied using broth macrodilution method against 125 strains of yeasts including 104 clinical and other isolates of Candida spp. (C.

The ability of the weak inorganic acids (H2S, HCN) and lower carboxylic acids to interact with bilayer lipid membranes (BLMs), change their conductivity, act as the protonophores were investigated. The mechanism of the BLM conductivity change was studied. The factors affecting the acids interaction with model lipid membranes were determined.
