UNLABELLED Periareolar (PA) injection offers several potential advantages over other techniques for visualizing sentinel lymph nodes (SLNs) in patients with early breast cancer. However, few studies have been published on this procedure. This study was designed to validate PA injection technique and compare it with the subdermal/peritumoral (SD/PT) injection technique. METHODS The study inclu...

background and aims. different materials have been used for root-end filling during surgical endodontic treatment. the aim of this in vitro study was to evaluate the dye penetration in different thicknesses of calcium enriched mixture (cem) cement as root-end filling material. materials and methods. following root canal filling in 70 extracted human single-rooted premolar teeth, the apical 3 mm...

zno and tio2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. dye-modified zno and tio2 showed significantly higher photocatalytic activity than neat zno and tio2 under visible light illumination. moreover, the prepared dye-modified zno showed superior photocatalytic efficiency in degradation of phenol compared to the dye-modified t...

of cancer with the hope of developing useful diag nostic and therapeutics agents. The aim in such investigations has been to find a dye which, in the intact animal, stains living tumor cells without staining surrounding tissue. A large number of acid dyes, especially in the azo series, has been rather intensively investigated for such a purpose. From these investigations there has resulted gen ...

Titania coated silica spheres (SiO2@TiO2) prepared by heterocoagulation of silica and titania nano-particles were investigated as catalyst in he photodegradation of rhodamine B (RB) in aqueous solution. The silica spheres were prepared by the well-known Stöber method and titania ol by a hydrolysis–condensation reaction in acidic media. The uncoated and coated particles were characterized by zet...
