Polydrug use was common regardless of the cause of death. In the age group 15 to 24 years, concomitant use of benzodiazepines and illicit drugs, and buprenorphine poisoning were more prevalent than in the age group 25-64 years.

The unprecedentedly high concomitant use of benzodiazepines in buprenorphine user deaths obscures other possible…[Read more]

Streptococcus mutans is a gram-positive bacterium that causes tooth decay. The exopolyssacharides, mostly glucans synthesized by the bacterium are responsible for establishing pathogenic bio-films associated with dental caries disease. The regulatory immune and inflammatory reactions implicated by the synthesized glucans are still not clearly…[Read more]

The acetone extracts presented the lowest IC50 values (0.29-0.38 mg dry extract/mL) regarding O2•- scavenging, and revealed anti-inflammatory potential, with N. antarctica LEGE13457, A. pantanalense LEGE15481 and Leptolyngbya-like sp. LEGE13412 reducing the nitric oxide (NO) in RAW 264.7 cell culture medium in about 25% (p less then 0.05). With t…[Read more]

Traumatic dental injuries (TDIs) are frequent events during childhood, and emergency management of these injuries has positive outcomes.

The aim of this study was to evaluate the knowledge of parents of school-aged children about dental trauma and to identify the effect of demographic variables such as age, gender, and education on their…[Read more]

In this article, a newly developed test setup for the aging of optical plastics by visible radiation (450 nm) is presented. In addition to a comprehensive monitoring of the operating parameters and an efficient cooling of the high-power multiple chips on board the LEDs used, the plastic samples can be fully temperature-controlled, independent of…[Read more]
