The aim of the work was to study the effect of extract of walnut (Juglans regia L.

Changes in sex and non-sex hormones and distribution of erythrocyte antigens in reproductive age women with tumors of body of uterus in Adjara.

The aim the research was to study the hormonal state of reproductive age women with tumors of body of uterus. The quantitative changes of sex steroid hormones: progesterone (P), estradiol (E), testosterone (T), gonadotropine -Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) were investigated. Distribution of ABO blood group antigens and Rh-Hr systems genetic variants in the blood of women living in Adjara Region was also studied.

Distribution of erythrocyte phenotypic groups in women with benign tumors of the uterus in Adjara Oncology Centre.

ABO blood groups antigens have biological and clinical significance. The ABO blood groups antigens has been associated with many diseases, though the explanation between ABO blood groups and disease is still unclear. The aim of this study is to investigate the presence of a possible association between benign tumors of the utesus with blood ABO, RhD, Kell and MN groups in women in reproductive periods.

[Investigation of metabolic paramagnetic centers in the blood of patients with prostate adenocarcinoma prior to and after the plastic orchectomy].

Paramagnetic centers in the blood of patients with prostate adenocarcinoma have been studied prior to and after plastic orchectomy by EPR. It has been shown that significant alterations in blood paramagnetic centers occur after the surgery. These alterations point to an improvement of antioxidant properties of the blood.

Investigation of pro- and antioxidative systems' changes in blood of patients with prostate tumours.

Great number of pathogenic processes, including cancer, are followed by disbalance between pro- and antioxidative systems. This is reflected on lipid peroxidation (LP). As a result diene conjugates - the primary products of peroxidation, cetodienes, trienes (secondary products), malondialdehyde (MDA) and Schiff's bases (the final products) are synthesized.

Erythrocyte membrane permeability in the men with metastatic adenocarcinoma of the prostate.

The aim of our study was to investigate the alterations of the erythrocyte membrane permeability in the men with metastatic adenocarcinoma of the prostate before and six months after castration. For experimental research were used the erythrocytes of 15 men with metastatic prostate cancer (Pca) (before and after 6 months from castration) and of the 15 practically healthy men (control group). The patients age was vacillate from 60 to 75 years old.

Activity and content of antioxidant enzymes in prostate tumors.

Aim: To investigate the antioxidant enzyme system in blood of men with benign hyperplasia of prostate (BHP) and with prostate adenocarcinoma (CaP).

Methods: The spectrophotometrical methods were applied to study content and activity changes of superoxide-dismutase (SOD), catalase (CAT), ceruloplasmin (Cp), tripeptide glutathione (GSH), glutathione-peroxidase (GSH-Px), and glutathione-reductase (GR). Lipid peroxidation was evaluated using thiobarbituric acid (TBA)-test.

Dynamics of the structural and electrical characteristics of erythrocytes in men with metastatic adenocarcinoma of the prostate before and after plastic orchiectomy.

The changes of electrophoretic mobility of erythrocytes in the practically healthy men and in men with metastatic prostate cancer before and after castration were studied. The electrophoretic mobility of erythrocytes was investigated in laboratory conditions by Kharamanenko and Abramson micro methods. Experimental data were processed by means of standard variation statistics MINITAB (Basic statistic) p View Article and Find Full Text PDF

Dynamics of the protein spectrum changes in blood erythrocytes of male patients with prostate adenocarcinoma after plastic orchiectomy.

We have studied erythrocytes electrophoresis profiles in patients with prostate adenocarcinoma before and after plastic orchectomy and in healthy men to detect changes in the protein spectrum of erythrocytes. Our investigations have shown that during this pathology protein spectrum of erythrocytes structure undergoes substantial changes. This is demonstrated by losing of 35 KD molecular weight protein fraction and by appearance of 36 KD molecular weight protein fraction on the erythrocytes electrophoregram.

Mass spectrometric analysis of the HIV-1 integrase-pyridoxal 5'-phosphate complex reveals a new binding site for a nucleotide inhibitor.

HIV-1 integrase (IN) is an important target for designing new antiviral therapies. Screening of potential inhibitors using recombinant IN-based assays has revealed a number of promising leads including nucleotide analogs such as pyridoxal 5'-phosphate (PLP). Certain PLP derivatives were shown to also exhibit antiviral activities in cell-based assays.

[Regulation of catalytic properties of enzymes in "inverse micelles"].

A triple system (inverse micellae) that simulates the membrane environment of the enzyme was studied. Inverse micellae were obtained using anionic (aerosol OT), synthetic (Brij 56), and natural (lecithin) surfactants. It was found that upon inclusion of an enzyme into inverse micellae, its activity can be regulated by changing the structure and nature of the surfactant matrix.

[Change in lipid peroxidation, structural status and level of phospholipids in the blood of patients with fibroma and cancer of the uterus].

Study of physicochemical properties of lipids in the donor blood and blood of patients with fibroma and uterus cancer showed that the progress of pathological processes may lead to the rise of peroxidation and peroxide accumulation, phospholipid balance disturbance, that causes drastic changes in biomembranes. As a result of this the disturbance of the structure and change in the functional activity of the membranes take place.

[1H-NMR of blood lipids in malignant and benign tumors].

High-resolution 1H-NMR (360 MHz) combined with thin-layer chromatography was used to study profile and molecular structure changes of inverted micelles of human blood developing in patients with malignant and benign tumors of the breast and uterus. Alterations were demonstrated in relative intensities of some lipid NMR peaks in tumor, as compared to normal blood. Changes in blood lipid levels, e.

[Phospholipid composition of blood lipids in breast and uterine cancer].

A comparative analysis of quantitative changes in phospholipids, as well as peroxidation of undiluted blood lipids, plasma and blood cells in healthy women, those suffering from breast and uterus cancer, and from nonmalignant tumours (breast fibroadenoma and uterus fibroma) does not show any specific regularity typical of only malignant neoplasma and not typical of nonmalignant ones. Disturbances in the balance of negative charge phospholipids are supposed to change the electrostatic interaction in the lipid-protein complexes of supramolecular structures during the malignant growth.

[Thermoinduced structure reconstructions in lysosomal membranes and lipids during experimental carcinogenesis].

Thermoinduced structural transitions in lyzosome membranes and lipids during experimental cancerogenesis were considered. Unlike lipid aqeous systems the structural transitions in lipids were investigated in inside out turned with hydrophobic side vesicles in apolar and aproton solvent. Relationship between the structure change and the function of lyzosome membranes is discussed.
