Tumor markers CA 125, CA 19-9, and carcinoembryonic antigen (CEA) were measured in the blood sera of 396 inpatients of different age. In 139 patients the measurements were carried out over time. Hoffman La Roche enzyme immunoassay test kits were used. Eight groups of women were tested: controls without gynecological diseases, women in need of plastic repair(More)
The advantages and shortcomings of endoscopic and laser myomectomies in comparison with conventional myomectomy using laparotomy are discussed. A total of 279 patients with uterine myoma were subjected to myomectomy using laparotomy with CO2 laser (n = 109), laparotomy without laser (n = 45), laparoscopy (n = 120), and hysteroscopic removal of submucosal(More)
The first systematic access to molecular cerium vanadium oxides is presented. A family of structurally related, di-cerium-functionalized vanadium oxide clusters and their use as visible-light-driven photooxidation catalysts is reported. Comparative analyses show that photocatalytic activity is controlled by the cluster architecture. Increased(More)
Human peripheral blood values are used to define an effective dose at X-ray study. Processing is made on a technical unit comprising a blood analyzer and a computer supplied by a so-called automatic classifying system. The program is based on the recognition of images with nonstatistical assessment. A dose-effect could be first plotted in the range of(More)
The authors made an analysis of ultrasonic flowmetry in 36 operations of carotid endarterectomy in 22 patients with stenosis of brachiocephalic arteries. After removal of atherosclerotic plaques the volumetric blood flow in carotid arteries increased from 65-260 ml/min up to 210-400 ml/min. No substantial difference was noted between the increase of blood(More)
The effect of therapy of malignancies is at present monitored by X-ray procedures on the basis of the dynamics of the size of lesion. Since such approach fails to provide data on the structure of lesion changes and response to treatment, it is suggested that structural changes in cells of exposed tissues can by monitored by using densitometric data obtained(More)
Spectroscopic anion sensing is a vital non-invasive tool in chemistry and biology. Here, a molecular cobalt-vanadium-oxide cluster was shown to be capable of selectively binding and detecting various mono-anions in solution and immobilized on a solid support. The cluster anion [Co(X)V4 O12 ]3- (X=mono-anion, for example, halide, pseudohalide, carboxylate,(More)
The first example of a molecular cerium vanadium oxide photocatalyst is presented. A cerium vanadium oxide cluster, (nBu4N)2[(Ce(dmso)3)2V(IV)V(V)11O33Cl] × 2DMSO (1), was obtained by bottom-up self-assembly. The compound exhibits high visible-light photooxidative activity towards indigo with quantum efficiencies >10%. Initial mechanistic studies of the(More)
An anionic molecular cobalt vanadium oxide cluster, (n-Bu4N)3[Co(AcO)V4O12] and its use as anion binding site is reported. Cluster formation is controlled by an anion-dependent dynamic solution equilibrium. Reversible anion binding in solution leads to significant spectral changes, allowing the ratiometric optical detection of the anion concentration in(More)
