High-density polyethylene (HDPE) is one of the main materials used in the world, applied in the most varied human activities. Because of its extreme resistance, it take years to degrade in nature, causing buildup of large volumes of material in landfills, when it does not end up in aquatic habitats due to the lack of awareness by society. Therefore, the recycling of this material is important. In this context, the present study describes the recycling of HDPE from plastic bags with four extrusion cycles in a twin-screw extruder.

Oral cancer is among the most common cancers worldwide. More than 90% of oral cancers are oral squamous cell carcinoma (OSCC). Diagnosis of such malignant oral tumor are often at late state with poor prognosis and the survival rate is generally very low; So considering this fact, early detection of oral cancer is urgently needed. Many recent studies have been conducted to the search for early salivary biomarkers of oral cancers. Investigation of Salivary biomarkers are simple, non-invasive and inexpensive test.
