Acute Inhalation Exposure to Ultrafine Carbon Black Alters Mitochondrial Substrate Utilization in the Heart

Environmental Toxicology, EarlyView.
ABSTRACT A majority of deaths associated with air pollution are attributed to cardiovascular and heart diseases. Carbon black that represents the carbon core of particulate matter, a major component of air pollution, has been shown to result in cardiac mitochondrial dysfunction.

Dose‐Dependent Effects of Simulated Clinical Radiotherapy on the Structure and Properties of Root Dentine

Australian Endodontic Journal, EarlyView.
ABSTRACT Head and neck radiotherapy (HNRT) can expose teeth to moderate radiation doses, yet the effects on root dentine under clinically relevant conditions remain unclear. This in vitro study compared dentine subjected to 0, 30, or 50 Gy IMRT. Palatal roots from 35 maxillary molars were allocated to non‐irradiated, 30 Gy (oropharyngeal simulation ...
