Investigations of intact dental enamel as well as carious-affected human dental enamel were performed using infrared spectromicroscopy and X-ray diffraction applying synchrotron radiation. Caries of enamel was shown to be characterized by an increase in the number of deformation and valence vibrations for N-C-O, N-H and C=O bonds, a decrease of the crystallinity index, and by the absence of the preferable orientation of hydroxyapatite crystals within the affected enamel. This indicates the presence of destructive processes in the organic matrix of hard tooth tissues. © 2013 International Union of Crystallography Printed in Singapore-all rights reserved. Source

The review provides a general idea about the types of metallic alloys and the pure metals used as implant materials in dental and orthopedic surgery. Their corrosive behavior in both real solutions and various media that model human biological fluids is described. Based on the literature data, it is concluded that multicomponent alloys containing titanium, niobium, zirconium, tungsten, molybdenum, aluminum, and silicon are the most resistant to corrosion. Implants made of different types of stainless steel are preferred when manufacturing orthopedic devices for short-term use. © 2011 Pleiades Publishing, Ltd. Source

We report the synthesis of Y 1 - x Cd x FeO 3 - δ nanocrystals in the range x = 0-0.2. The Y 1 - x Cd x FeO 3 - δ materials were shown to be single-phase by X-ray diffraction, with an average crystallite size from 23 to 34 nm, depending on composition. With increasing cadmium oxide content, the size of the Y 1 - x Cd x FeO 3 - δ nanocrystals decreases and their magnetization rises. © 2011 Pleiades Publishing, Ltd. Source

Y 1 - x La x FeO 3 (x = 0, 0.1, 0.2, 0.3, 0.4) nanocrystals have been prepared by a sol-gel process. With increasing lanthanum content (x from 0 to 0.4), their size decreases significantly (from 34 to 16 nm), whereas their magnetization increases. Raising the annealing temperature increases their size. © 2011 Pleiades Publishing, Ltd. Source

We studied effect of therapy with fixed combination of lercanidipine and enalapril on 24-hour blood pressure (BP) profile in 34 elderly patients (mean age 76.4±5.2 years, 14 men, 20 women) with degree II hypertension. After clinical examination patients were given lercanidipine/enalapril combination (10/10 mg/day). The dose was increased to 10+20 mg/day when necessary. Assessment of efficacy was conducted on Rate of achievement of target BP [systolic (S) BP <150 mm HG, diastolic (D) BP<90 mmHg] and dynamics of parameters of 24-hour BP profile. Re-examinations were carried out on weeks 4.8 and 12 of treatment. Administration of lercanidipine/enalapril combination was associated with mean 24-hour SBP and DBP lowering (by15.3 and 8.7%, respectively). Diurnal and nocturnal SBP/DBP decreased by 15.7/9.2 and 14.1/8.5%, respectively. BP variability also significantly decreased: of diurnal SBP/DBP - 3.8/4.1 mm Hg (21.7/24.7%), of nocturnal SBP/DBP - 2.8/4.1 mm Hg (17.9/19.6%). There was no significant dynamics of the heart rate. Therapy with lercanidipine/enalapril combination for 12 weeks did not lead to the deterioration of carbohydrate, lipid metabolism, or renal function. Thus using lercanidipine/enalapril combination we observed pronounced antihypertensive effect which consisted in decrease of mean BP and normalization of BP circadian rhythm of blood pressure.
