Deconvolution of the particle size distribution of ProRoot MTA and MTA Angelus [PDF]
Acta Biomaterialia Odontologica Scandinavica, 2016 Objective Mineral trioxide aggregate (MTA) cements contain two types of particles, namely Portland cement (PC) (nominally 80% w/w) and bismuth oxide (BO) (20%). This study aims to determine the particle size distribution (PSD) of PC and BO found in MTA. Materials and methods The PSDs of ProRoot MTA (MTA-P) and MTA Angelus (MTA-A) powder were determined

Failure of orthograde MTA filling: MTA wash-out? [PDF]
Journal of Korean Academy of Conservative Dentistry, 2011 Mineral trioxide aggregate (MTA), which was originally developed for repair of root perforations, is a biocompatible material with numerous clinical applications in endodontics. MTA must be allowed to set in the presence of moisture to optimize the material’ s physical and chemical properties.

Magnetic Thermal Ablation Combined with Temporally Coordinated CpG Immunotherapy Promotes cDC1‐Dependent Immune Priming in Hepatocellular Carcinoma [PDF]
Advanced scienceNovel PLA@Fe3O4 magnetic microspheres were developed for transarterial magnetic hyperthermia ablation (MTA) of hepatocellular carcinoma. While destroying local tumors and inducing immunogenic cell death (ICD), MTA combined with early CpG adjuvant administration significantly promotes cDC1‐dependent immune priming. This synergistic mechanism effectively

Journal of the Royal Society of Medicine, 2007 As we move ever closer to the start of August, there remains no sign that the MTAS (Medical Training Application Service) debacle will end. In the months since this sorry episode began, doctors have been united in a way never seen before,1 and the common goals of those professionals who have invested so much of themselves in the NHS are becoming ...

Clinical studies with MTA [PDF]
British Journal of Cancer, 1998 MTA (LY231514), a multi-targeted antifolate, is a classical antifolate undergoing intracellular polyglutamation. Polyglutamated MTA is a potent thymidylate synthase (TS) inhibitor and inhibits other folate-dependent enzymes, including dihydrofolate reductase and glycinamide ribonucleotide formyl transferase.
