The aims of this study were to evaluate the ratio between inflammatory reactions induced by four endodontic sealers and the occurrence of fibrosis and the number of myofibroblasts with positivity to α-smooth-actin muscle (α-SMA). Polyethylene tubes were filled with a root canal sealer (Endofill, AH Plus, Acroseal and Epiphany) and inserted into 4 site at the dorsal region of 24 Wistar rats; 2 e...

AIM The aim of this study was to evaluate the fracture strength (FS) of bovine incisors with simulated incomplete rhizogenesis (IR) after different intraradicular treatments. MATERIALS AND METHODS Incomplete rhizogenesis was simulated by sectioning the crowns and roots of 40 bovine incisors. Root canal preparation was performed and the samples divided into 4 groups (n = 10): GI-negative contr...

The energy-efficient Adapteva Epiphany architecture exhibits massive many-core scalability in a physically compact 2D array of RISC cores with a fast network-on-chip (NoC). The architecture presents many features and constraints which contribute to software design challenges for the application developer. Addressing these challenges within the software stack that supports application developmen...

IN THE November issue of Nursing Management, airline pilot Chris Mann asked: 'Safety Culture? What safety culture?' ( Mann 2004 ). His paper summarises the training undertaken in the aviation industry particularly in relation to human factors, in recognition of their part in aviation safety. He posed the following questions of the NHS.

UNLABELLED   INTRODUCTION Blood contamination of the canal during preparation can be a major problem in endodontics; this may result in apical microleakage. The aim of this in vitro study was to evaluate the effect of blood on apical microleakage of a resin-based root canal sealer (AH26) and a polymer-based root canal sealer (Epiphany). MATERIALS AND METHODS In this experimental study, 50 d...

this paper examined disagreement in two sets of data in the context of service encounters: problem-solving interactions (doctor-patient communication) and purchase-oriented encounters (pharmacies) from a cross-cultural perspective (spanish-british english). we proposed assertiveness, a term that refers to both socio-psychological and linguistic features of communication, as a concept that may h...
