[Potentialities of photoactivated disinfection in dentistry].

Infection control is an essential part of dental practice. Oral antiseptics should be highly effective against the most common oral pathogens without causing microbial resistance, biocompatible with the human tissues with no interaction with fillings materials. Photoactivated disinfection (PAD) is based on activation of photosensitizers - specific substances releasing active oxygen forms after absorption of the light.

A Sorbent with Synthetic Ligand for Removing Pro-atherogenic and Pro-inflammatory Components from Human Blood Plasma.

Elevated levels of apoB-100 containing lipoproteins and markers of systemic inflammation are often observed in patients with cardiovascular diseases. The concentrations can be reduced by pharmacotherapy or extracorporeal treatment. The sorbent, which removes CRP and atherogenic lipoproteins, simultaneously reduces the bloodstream concentration of these components.

Effect of Evolocumab on Lipoprotein(a) and PCSK9 in Healthy Individuals with Elevated Lipoprotein(a) Level.

The aim of this study was to investigate the influence of a single injection of Evolocumab on the dynamics of Lp(a), fractions of apoB100-containing lipoproteins, PCSK9, and their complexes in healthy individuals with elevated Lp(a) levels. This open-label, 4-week clinical study involved 10 statin-naive volunteers with Lp(a) >30 mg/dL, LDL-C < 4.9 mmol/L, and a moderate risk of cardiovascular events.

A Low-Molecular-Weight Phenotype of Apolipoprotein(a) as a Factor Provoking Accumulation of Cholesterol by THP-1 Monocyte-Like Cells.

Increased concentration of lipoprotein(a) is a risk factor of coronary heart disease. lipoprotein(a) consists of LDL-like and highly polymorphic apolipoprotein(a). Here we studied the effect of lipoprotein(a)-containing sera with different apolipoprotein(a) phenotypes on lipid accumulation by THP-1 monocyte-like cells.

[Molar-incisor hypomineralization among 12-years old children in Arkhangelsk region].

Aim: To estimate the prevalence of molar incisor hypomineralisation (MIH) across genders and place of residence as well as its association with dental caries among 12-years-old children in Northwest Russia.

Method: A cross-sectional study included 1233 (653 girls) randomly selected 12-years-old children from 7 urban and 5 rural areas of Arkhangelsk region. MIH and its severity were diagnosed using Weerheijm et al (2003) and Mathu-Muju & Wright (2006) criteria.

Apolipoprotein(a) phenotype determines the correlations of lipoprotein(a) and proprotein convertase subtilisin/kexin type 9 levels in patients with potential familial hypercholesterolemia.

Background And Aims: The aim of this study is to investigate the relation between lipoprotein(a) [Lp(a)] and proprotein convertase subtilisin/kexin type 9 (PCSK9) concentrations, and their complex, in patients with potential familial hypercholesterolemia (FH), depending on apo(a) phenotype.

Methods: The study included 205 patients with total cholesterol (TC) > 7.5 mmol/L and/or low density lipoprotein cholesterol (LDL-C)>4.

[Elevated Lipoprotein(a) Cncentration and Presence of Subfractions of Small Dense Low Density Lipoproteins as Independent Factors of Risk of Ischemic Heart Disease].

Aim: To study relation of lipoproteina - Lp(a) and subfractional composition of apoB containing lipoproteins to the presence of ischemic heart disease (IHD). Manerial and methods. Parameters of lipid spectrum, Lp(a), and subfractions of apoB containing lipoproteins were determined in blood serum of 187 patients with known data of instrumental examination.

[The effect of increased concentration of lipoprotein (a) on identification of sub-faction of lipoproteins using native electrophoresis technique].

The quantitative analysis of sub-fractions of lipoproteins acquires growing significance in diagnostic and prognosis of cardiovascular diseases. It is well known that presence of lipoprotein (a) in high concentrations significantly distorts results of biochemical analysis, in particular detection of level of cholesterol of low-density lipoproteins. The lipoprotein (a) is a heterogeneous particle and its mobility in the systems used for analysis of sub-fractions of lipoproteins can have significant variability that will bring inaccuracy into results.

[Effect of cascade plasma filtration on spectrum of subfractions of low density lipoproteins in blood plasma of patients with ischemic heart disease].

We studied effect of cascade plasma filtration on subfractions of low density lipoproteins (LDL) in 16 patients with ischemic heart disease (IHD) and hyperlipidemias refractory to drug therapy. The procedure caused 37.6 ± 1.

[Soluble receptors for tumor necrosis factor and lipid metabolism as potential prognostic factors in patients with prostate cancer].

There was investigated the relationship of lipid metabolism, humoral immunity, high sensitivity C-reactive protein and soluble receptors for TNF-alpha with the presence, severity and prognosis of the disease in 85 patients with morphologically verified diagnosis of prostate cancer. Connection with the dynamics of change in PSA as a major predictor of the disease was observed for concentration sRI and sRII to TNF, PSA baseline, total cholesterol and LDL-cholesterol. During follow-up the relative risk of poor prognosis increased by 3 times, and death-in 8.

Effect of specific lipoprotein(a) apheresis on coronary atherosclerosis regression assessed by quantitative coronary angiography.

Aim: To evaluate the effect of specific lipoprotein(a) [Lp(a)] apheresis on coronary atherosclerosis progression in coronary heart disease (CHD) patients with elevated Lp(a) levels.

Methods: A total of 30 subjects (mean age 53.5 ± 8.

[Effect of flavonoids of different structure on peroxidation of neutral lipids of animal origin].

The effect of flavonoids of different structure (baikalein, baikalin, quercetin, dihydroquercetin, genistein, and daidzein) on the process of formation of lipid hydroperoxides during thermoinduced autooxidation of neutral lipids of animal origin. The minimum inhibitory concentration of isoflavones was found to be equal to 10(-3) M. Effective inhibitory concentration of other flavonoids (except baikalin) was equal to 10(-4) M.

[Effect of genistein and daidzein obtained by acid hydrolysis of their glycosides on phospholipid peroxidation].

A mixture of isoflavones was obtained by acid hydrolysis of isoflavone glycosides isolated from the products of soybean processing by a successive extraction with aqueous acetone and methanol. Homogeneous isoflavones genistein and daidzein were isolated from the aglycone mixture by adsorption chromatography and identified by spectral and chromatographic methods. The effect of both isoflavones on lipid peroxidation of soy phospholipids in multilamellar vesicles was studied at various concentrations.

[Magnetic-resonance tomography in diagnosis of hepatopancreatoduodenal tumors].
