    We study experimentally the photoluminescence of small glycine-coated silver nanoparticles and their application as the bio-imaging markers of the neural stem cells. In addition we study nanoparticle’s toxic effects on the neural stem cells. Glycine-coated silver nanoparticles were synthesized using a thermal reduction of silver nitrate in a glycine matrix and size-separated via centrifugation. The properties of the nanoparticles were characterized using transmission electron microscopy, extinction and photoluminescence spectroscopy. Our results indicate that the nanoparticles have deleterious effects on the cells and showed an amplified increase in their death rates. In fixed cells the particles penetrate the membranes within an hour and 25 minutes of incubation, but do not penetrate into the body of the cell

    Aim. To determine a potential role of single-nucleotide polymorphisms in the genes involved in the DNA methylation process (MTHFR, MTR, TYMS) in the breast cancer risk and risk of leukemia in a case-control study from West Ukraine. Methods. Genotyping of MTHFR 677 C>T, MTR 2756 A>G and TS 3R2R, TS 3RG>C was performed in 60 patients with leukemia, 90 patients with breast cancer and in 100 persons from a control group. The molecular-genetic analysis was performed by Polymerase Chain Reaction and Restriction Fragment Length Polymorphism analysis. A statistical analysis was conducted by Chi-square tests and odds ratio (OR) calculation. Results. We did not observe any significant difference in genotype frequencies of the MTHFR and TYMS polymorphisms between the cases and controls. The MTR 2756AA genotype frequency was significantly higher in the patients with breast cancer vs control (0.67 vs 0.50, p = 0.02) and the difference between the patients with leukemia and the control group was not statistically significant. The increased risk of breast cancer development was associated with the MTR 2756AA genotype (OR = 2.00, CI – 95 %:1.11–3.60) and the MTR 2756A allele (OR = 1.75, CI–95 %:1.08–2.84). Conclusions. Our findings show that West Ukrainian inhabitants carrying at least one MTR 2756A allele have a significantly increased risk of breast cancer.ΠœΠ΅Ρ‚Π°.

    CdSe nanoparticles grown with different chelates

    No full text
    Modified reverse micelles method allowing fabrication of CdSe nanoparticles in toluene solution in series of sizes with average diameter from 1.2 to 3.2 nm and size distribution ∼ 12-30 % is presented. Simple empirical relation between the CdSe nanoparticle diameter and exciton absorption wavelength is proposed, which allows to do prompt and effective monitoring the particles size and size distribution during the synthesis. Optical absorption and photoluminescence measurements as well as EDX demonstrated good quality of obtained nanocrystallites. Besides, study of nanoparticles produced using two complexing agents (SNTA and Trilon B) revealed similar stoichiometric and optical properties. Trilon B is suitable for CdSe nanoparticles growth instead of SNTA. Because of higher stability of the chelate complex of Trilon B and Cd²⁺ ions, it is possible to use higher temperature for growth which allows preparation of large size nanocrystals
