Electrodeposited hydroxyapatite coating on titanium after ultrashort-pulsed laser processing for a novel surface of endosseous implants.

Background: Ceramic endosseous implant coatings have gained esteem due to their favorable osteoinductive and osteoconductive properties. However, such a layer may be prone to failure under in vivo conditions, which necessitates its modification.

Objectives: The aim of the present study was to modify an electrodeposited hydroxyapatite (HA) coating on titanium (Ti) with ultrashort-pulsed lasers for the incorporation of the ceramic into the sample surface and the texturing of the metal surface.

Solidified Salt Melts of the NaCl-KCl-CeF-EuF System as Promising Luminescent Materials.

This study presents the results of investigating the interaction between the CeF₃-EuF₃ system and the NaCl-KCl salt melt using spectroscopic methods. It was found that CeF₃ ions undergo no significant changes upon dissolution in the NaCl-KCl melt. In contrast, the dissolution of EuF₃, both individually and within the CeF₃-EuF₃ system, is accompanied by redox reactions leading to the formation of Eu⁺.

Hydroxyapatite or Fluorapatite-Which Bioceramic Is Better as a Base for the Production of Bone Scaffold?-A Comprehensive Comparative Study.

Hydroxyapatite (HAP) is the most common calcium phosphate ceramic that is used in biomedical applications, e.g., as an inorganic component of bone scaffolds.

Functionalization of Polycaprolactone Electrospun Osteoplastic Scaffolds with Fluorapatite and Hydroxyapatite Nanoparticles: Biocompatibility Comparison of Human Versus Mouse Mesenchymal Stem Cells.

A capability for effective tissue reparation is a living requirement for all multicellular organisms. Bone exits as a precisely orchestrated balance of bioactivities of bone forming osteoblasts and bone resorbing osteoclasts. The main feature of osteoblasts is their capability to produce massive extracellular matrix enriched with calcium phosphate minerals.

Alternative Approach for Fighting Bacteria and Fungi: Use of Modified Fluorapatite.

The recent studies on fluorapatite and hydroxyapatite, in the context of their medical applications, have shown that the former has relatively higher thermal stability and better mechanical properties than the latter. Moreover, the presence of fluoride ions is relevant for protection of teeth from dental caries since they stimulate processes of mineralization and crystallization. In this report, a silver modified fluorapatite (FAP/Ag), considered as a novel biomedical compound, was tested for its bactericidal, fungicidal and cytotoxicity activity.

Characterization and influence of hydroxyapatite nanopowders on living cells.

Nanomaterials, such as hydroxyapatite nanoparticles show a great promise for medical applications due to their unique properties at the nanoscale. However, there are concerns about the safety of using these materials in biological environments. Despite a great number of published studies of nanoobjects and their aggregates or agglomerates, the impact of their physicochemical properties (such as particle size, surface area, purity, details of structure and degree of agglomeration) on living cells is not yet fully understood.

Pregnancy outcomes in oocyte recipients with fibroids not impinging uterine cavity.

Objective: To examine the effects of fibroid uterus on pregnancy outcomes and endometrial features in ovum donation recipients.

Methods: Retrospective analysis of 744 ovum donation cycles was conducted in two private IVF centers between 2005 and 2012. All the recipients underwent transvaginal ultrasound examination, including endometrial thickness and grade measurements.

Effect of local endometrial injury on pregnancy outcomes in ovum donation cycles.

Objective: To evaluate the effect of local endometrial injury (LEI) on clinical outcomes in ovum donation recipients.

Design: Retrospective cohort analysis of ovum donation cycles conducted from 2005 to 2012.

Setting: Two private IVF centers.

Objective: To evaluate the combined effect of endometrial thickness and anatomic uterine factors on clinical outcome in oocyte donation recipients.

Design: Retrospective analysis of oocyte donation cycles conducted between 2005 and 2010.

Setting: Two private IVF centers.
