[Familial diabetes frequency as a factor in diabetics suffering from cancer].

Voprosy onkologii

Bershteĭn LM, Boriakina MP, Teslenko SIu, Vasil'ev DA.
PMID: 22191231
Vopr Onkol. 2011;57(4):443-7.

Although type 2 diabetes contributes to the risk of development of certain tumors; factors which modify this relationship need to be further examined. Familial diabetes frequency was followed in (a) diabetes-free cancer patients (132), aged 60.3 +/- 1.2; (b)...

Two types of PS II centres as manifested by light saturation of delayed fluorescence from DCMU-treated chloroplasts.

Photosynthesis research

Vasil'ev IR, Komarov AI, Matorin DN, Verkhoturov VN, Venediktov PS.
PMID: 24420462
Photosynth Res. 1990 Nov;26(2):101-7. doi: 10.1007/BF00047081.

Intensity of 2 s delayed fluorescence (DF) as a function of steady-state actinic light intensity was investigated in pea chloroplasts in the presence of 10 μM DCMU. The light saturation curve of DF was approximated by a sum of...

STED properties of Ce3+, Tb3+, and Eu3+ doped inorganic scintillators.

Alekhin MS, Renger J, Kasperczyk M, Douissard PA, Martin T, Zorenko Y, Vasil'ev DA, Stiefel M, Novotny L, Stampanoni M.
PMID: 28158009
Opt Express. 2017 Jan 23;25(2):1251-1261. doi: 10.1364/OE.25.001251.

Scintillator-based X-ray imaging is a powerful technique for noninvasive real-space microscopic structural investigation such as synchrotron-based computed tomography. The resolution of an optical image formed by scintillation emission is fundamentally diffraction limited. To overcome this limit, stimulated scintillation emission...

[Capabilities of complex radiodiagnostic methods in risk-group children in primary tuberculosis infection].

Problemy tuberkuleza i boleznei legkikh

PMID: 19256008
Probl Tuberk Bolezn Legk. 2009;(1):24-7.

Follow-ups of 39 children aged 3 to 12 years who had various biomedical risk factors of local forms of primary tuberculosis. Difficulties in diagnosing the local clinical forms of primary tuberculosis with minor clinical and X-ray signs are shown....

Multi-terawatt picoseconds 10-μm СО2 laser system: design and parameters' control.

Optics express

Bravy BG, Chernyshev YA, Gordienko VM, Makarov EF, Panchenko VY, Platonenko VT, Vasil'ev GK.
PMID: 23187371
Opt Express. 2012 Nov 05;20(23):25536-44. doi: 10.1364/OE.20.025536.

The basic principles for design of an advanced multi-terawatt СО(2) laser system are considered. The key amplifiers' parameters were evaluated by numerical modeling. The potential advantage of using pulsed chemical DF-СО(2) laser as a final amplifier over an electro-ionization...

Perspectives for CdSe/CdS spherical quantum wells as rapid-response nano-scintillators.


Meng Z, Mahler B, Houel J, Kulzer F, Ledoux G, Vasil'ev A, Dujardin C.
PMID: 34807212
Nanoscale. 2021 Dec 02;13(46):19578-19586. doi: 10.1039/d1nr04781g.

We explore the effect of the shell thickness on the time response of CdS/CdSe/CdS spherical quantum wells (SQWs) nanoscintillators under X-ray excitation. We first compare the spectral and timing properties under low and intense optical excitation, which allows us...

The decay kinetics of the excitonic emission of CdWO4 scintillators was studied under excitation by powerful 100 fs laser pulses in the band tail (Urbach) absorption region. A special imaging technique possessing both spatial and temporal resolution provided a...

Novel preparation of alpha,beta-unsaturated aldehydes. Benzeneselenolate promotes elimination of HBr from alpha-bromoacetals.

The Journal of organic chemistry

Vasil'ev A, Engman L.
PMID: 10774040
J Org Chem. 2000 Apr 07;65(7):2151-62. doi: 10.1021/jo9917644.

Acetalization, alpha-bromination, nucleophilic phenylselenenylation, oxidative elimination/hydrolysis was investigated as a novel protocol for the alpha,beta-dehydrogenation of aldehydes. Treatment of acetals with bromine in methylene chloride afforded the corresponding alpha-bromoacetals in 80-90% yields. Nucleophilic phenylselenenylation was then conveniently effected by...
