introduction: in apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. mineral trioxide aggregate (mta) is the gold standard material for this purpose. changing water/powder ratios of mta affects its properties. the purpose of this in vitro study was to determine the effect of liquid/powder ratio of retrofil...

IN THE PERPETUALLY RESOURCE-STARVED environment of public health, where each disease or risk factor has to fight for a scrap of the federal budget, it is easy to forget how fast progress can be made when appropriate policy attention and resources are marshaled to solve a problem. The natural response of public health professionals to the starvation diet is to maintain low expectations. But thos...

Application of the Next generation sequencing (NGS) technology has demonstrated that most tumor samples exhibit intra-tumor heterogeneity. Here we proposed SAPPH (Somatic Aberrations Prediction for Paired Heterogeneous tumor samples), as a new method for estimating tumor somatic copy number aberrations as well as inferring tumor subclone proportions from heterogeneous tumor sequencing data. Thi...
