Factors that inhibit the analysis of bodily fluids can result in inaccurate determinations by forensics experts. This paper points out the issues with the current practical tests focused on contamination of forensic samples and inhibition of testing. Several previous studies have shown that there are inhibitory substances that prevent the accurate identification of blood, saliva, and semen. Alt...

introduction: the success of endodontic treatment depends on the method and quality of cleaning, disinfection and three-dimensional sealing of the root canal. the smear layer can play an important role in the success or failure of endodontic treatment. there is controversy over the presence or removal of the smear layer in relation to the success or failure of endodontic treatment. this study u...

We have developed a new method for directly using unprocessed biological specimens as templates for the TaqMan assay. DNA extraction and purification had been believed to be required for the assay, but our new method could avoid hindering fluorescence detection, even if the templates were used directly. Saliva was needed to be put on water-soluble paper and dried, and hairs were cut to be about...

Mucosal ulcers of less than 3 weeks' duration are usually identified. Lesional borders may be slightly raised, with a peripheral red halo. The center of the lesion is frequently filled with yellow to brown necrotic debris. The surface may be crusty, especially in the areas on the lips which are not continually bathed in saliva. The traumatic ulcer will often conform to the shape of the initiati...

The recent surge in the use of filtering facepiece respirators (FFRs) during SARS-CoV-2 pandemic triggered economic and environmental concerns with regards to their safe reuse and/or disposal. Their decontamination through ultraviolet (UV) irradiation has proven efficient bench tests. Nevertheless, no study yet investigated what extent method’s performance was impacted by contamination method. ...
