Background: Little is known regarding the extent or targets of phosphorylation in mycoplasmas, yet in many other bacterial species phosphorylation is known to play an important role in signaling and regulation of cellular processes. To determine the prevalence of phosphorylation in mycoplasmas, we examined the CHAPS-soluble protein fractions of Mycoplasma genitalium and Mycoplasma pneumoniae by...

Ex-Vivo Comparison of the Dentin Removal Ability of One Shape and F6 SkyTaper Rotary Files

Background and Aim: One of the important characteristics of nickel-titanium (Ni-Ti) rotary files is their dentin removal ability. The purpose of this study was to compare One Shape and F6 SkyTaper files in terms of dentin removal from the mesiobuccal canals of extracted first mandibular molars. Materials and Methods: In this experimental study, 24 mesiobuccal canals of extracted first mandib...

NTP Update

The use of heat treatment for the removal of non-specific effects in the direct radioimmunoassay of human circulatory CEA has been widely adopted have shown the existence of heat-labile determinants on CEA which may be destroyed by this assay technique. Heat-labile antigens appeared to be shared between CEA isolated from tumour and normal colon whilst the heat-stable antigens appeared to be mor...

NTP Research Concept: Furan

program prior to designing and conducting toxicology studies. The purpose of the research concept document is to outline the general elements of a research program that would address the specific public health concerns that prompted the nomination of the substance or issue for study. It may also encompass substance-specific studies that address larger public health issues or topics in toxicolog...
