myeloid sarcoma (ms) is a tumor mass consisting of myeloblast with or without maturation occurring at an anatomical site other than the bone marrow. incidence of ms ranges from 1-9% and is most commonly misdiagnosed as non hodgkins lymphoma or poorly differentiated carcinoma. ms can occur in various sites but nasal cavity involvement is rare. here we report acaseof ms presenting as nasal polyp ...

Restoration of endodontically treated teeth is one the major challenges faced in field operative dentistry. In tooth, most part tooth structure lost because dental caries, conventional access cavity preparation and biomechanical during root canal therapy. They become very weak brittle also more prone to fracture compared vital

Background and Aim: Tooth discoloration induced by endodontic sealers is an un-desired outcome of endodontic treatment that affects the esthetic appearance of the teeth, which is important especially in the anterior region. The aim of the present study was to compare the coronal discoloration caused by two frequently used resin-based sealers namely EasySeal and AdSeal. Materials and Methods: F...

The Escherichia coli DegP protein is an essential periplasmic protein for bacterial survival at high temperatures. DegP has the unusual property of working as a chaperone below 28 degrees C, but efficiently degrading unfolded proteins above 28 degrees C. Monomeric DegP contains a protease domain and two PDZ domains. It oligomerizes into a hexameric cage through the staggered association of trim...

OBJECTIVE A randomised controlled trial to determine the acceptability to dentists and patients of cavity preparation with an Erbium:YAG laser as compared with conventional handpieces. METHODS Fifteen dentists (9 GDPs, 1 community dentist and 5 hospital dentists) treated 77 patients (age range 3.5-68 years old) who had two matched cavities, in a split mouth, randomised trial. One cavity was p...

Introduction: Cervical root resorption is one of the most important complications of intra coronal bleaching. A way of preventing this type of resorption is using a coronal barrier under the bleaching materials. The aim of this study was to compare the sealing ability of glass ionomer cement and Pro Root Mineral Trioxide Aggregate (MTA) as a coronal barrier in intra coronal bleaching. Materi...

We apply a microscopic theory of exciton-polaritons in cavity-confined monolayer transition-metal dichalcogenides including both optical polarizations the plane, allowing to describe how chiral cavity photons interact with valley degrees freedom active material. Upon polariton formation, degenerate excitons inhabiting two inequivalent valleys are shown assume bonding and antibonding superpositi...
