Mechanical Properties and Corrosion Resistance of Thin Ceria and Phosphate Mono- and Multilayers Deposited on Technically Pure Al 1050.

Calcium phosphates are often used for biomedical applications. Hydroxyapatite, for example, has a wide range of applications because it mimics the mineral component of natural bone. Widespread interest in the catalytic properties of ceria is due to its use in automotive catalytic converters.

Investigation of mechanical and physicochemical properties of clinically retrieved titanium-niobium orthodontic archwires.

Purpose: Most of the orthodontic archwires used in the clinical practice nowadays contain nickel (Ni), however, many patients, especially kids, are allergic to Ni. One possible Ni-free alternative is the Titanium-Niobium (Ti-Nb) archwire. Unfortunately, there is not enough information about its mechanical properties in the literature, especially after clinical usage.

[Main principles and IVF-ET results of the centre for assisted reproduction "Varna", Bulgaria].

The authors formulate the main principles of IVF-ET, based on personal experience i.e. hormonal ovarian stimulation, ovarian puncture, fertilization and ET, prophylaxis and therapy of early complications.

[Measurement of endometrial volume and endometrial thickness for assessment of endometrial receptivity in assisted reproductive techniques].

The authors investigated the role of 3D endometrial volume measurements as a predictor of clinical pregnancy in ART and comparison between endometrial volume and endometrial thickness in order to find the better predictor for endometrial receptivity in ART. Endometrial volume emerged recently as a new efficient predictor of endometrial response to hormonal stimulation and successful implantation. In this clinical study, participated 58 infertile patients undergoing IVF-treatment, during the period from 01.

[Role of intercellular adhesion molecule-1 and E-selectin in the pathogenesis of ovarian hyperstimulation syndrome].

Objective: To explore the ICAM-1 and E-selectin in patients with OHSS and clarifying its role in pathogenesis of the syndrome.

Materials And Methods: 20 patients were included in the research and 20 control patients with stimulating ovarian cycle for the purposes of ART, during the period from 01.01.
