The biodegradable magnesium-based implants have been widely utilized in medical orthopedic applications in recent years. We have recently shown that direct culture on Pure Mg and Mg2Ag alloys lead to a progressive differentiation impairment of MC3T3-E1 pre-osteoblasts. In this study, we aimed to analyze the apoptotic reaction of MC3T3-E1 cells in response to the direct culture on Pure Mg, Mg2Ag...

The aim of the study was to investigate the influence of dental alloys and their components on magnetic resonance imaging of the temporomandibular joint. A plaster and a water- filled acrylic resin phantom - representing the disc and the condyle of the TMJ - were used. Cylindrical crow-type samples of 13 alloys and 14 pure substances were investigated. All alloys were examined with regard to th...

Because of environmental and health concerns, some alternative solder alloys, named lead-free ones, are being developed. Among them, the Sn-Zn-Al system has been studied and reveals promising properties. Selection of the solder alloys, for the electronic industry applications, is conditioned by their mechanical properties due to the stress produced in service. The studied alloys were produced b...

The electrochemical formation of Neodymium–Nickel (Nd–Ni) alloys was investigated in a molten CaCl 2 –NdCl 3 (1.0 mol%) system at 1123 K. Cyclic voltammograms for Molybdenum (Mo) and Ni electrodes showed the electrodeposition/dissolution metallic Nd formation/dissolution Nd–Ni alloys, respectively. equilibrium potential 3+ /Nd determined 0.27 V (vs. Ca 2+ /Ca) by open-circuit potentiometry Mo e...

A very simple, ultra-sensitive and highly selective non-extractive spectrophotometric method for the determination of trace amount of vanadium(V) using 2-Hydroxyacetophenobenzoylhydrazone(HAPBH) has been developed. 2-Hydroxyacetophenobenzoylhydrazine(HAPBH) reacts in slightly acidic (0.0005-0.025M H2SO4) 50% 1,4-dioxane media with vanadium(V) to give a yellow chelate which has an absorption max...

The long-term effects of metal-on-metal arthroplasty are currently under scrutiny because of the potential biological effects of metal wear debris. This review summarises data describing the release, dissemination, uptake, biological activity, and potential toxicity of metal wear debris released from alloys currently used in modern orthopaedics. The introduction of risk assessment for the evalu...
