    The anti-microbial activity of calcium hydroxide pastes used in endodontics is dependent on establishing high levels of hydroxyl ions in dentine. This study investigated hydroxyl ion diffusion from different commercial calcium hydroxide pastes using a novel colourimetric method. In this method, human tooth roots were stained with anthocyanin dye, which changed their colour according to the local pH conditions. Read More

    Duplicated middle cerebral artery origin with an aneurysm.
    Medicine (Baltimore) 2018 Mar;97(9):e9947
    Department of Neurosurgery, Tianjin Huanhu Hospital, Tianjin, China.
    Rationale: Middle cerebral artery (MCA) anomalies are relatively rare and often related to aneurysms. Familiarity with these anomalies is important in resolving problems that arise in the complex angioarchitecture. Reports often describe that aneurysms that are related to accessory or duplicated MCA are often located at its origin. Read More

    Department of Anatomy and Embryology, Faculty of Veterinary Medicine, Beni-Suef University, Beni-Suef 62511, Egypt.
    The aims of the present study were to describe the normal ultrasonographic, magnetic resonance imaging (MRI) and computed tomographic (CT) appearances of the bovine metacarpo/metatarsophalangeal (MCP/MTP) joints and to assess the normal cross-sectional dimensions of the superficial (SDFT) and deep (DDFT) digital flexor tendons. A systematic ultrasound examination was performed on the MCP/MTP joints of 22 healthy cattle and two bovine cadavers, and the cross-sectional dimensions of the SDFT and DDFT were recorded. The cadaveric MCP/MTP joints (n=8) were scanned using a 16-slice multi-detector CT scanner and a 1. Read More
