Activated Ca ncer Ther apy ( ACT), al so know n a s Sonodyna mic Phot odynamic Ther apy ( SPDT) i s a nove l therapeutic modality that utilises a non-toxic photosensitive agent with reported ultrasound-activated properties. SPDT has previously demonstrated significant tumour cell inhibition in animal studies. There has been much research into the efficacy of phot odynamic therapy and developmen...

Introduction: Breast cancer is the most common cancer among women in the world and in Iran. Sono- photodynamic therapy is a new modality for cancer treatment. In this method, a sensitizer that activates by ultrasound and light produces photochemical and synchochemical activities, thereby causing the toxicity and destruction of tumor cells. The use of dual frequency ultrasound...

introduction : halitosis is a common problem that affects a large portion of the population worldwide. the origin of this condition is oral in 90% of cases and systemic in 10% of cases. the foul odor is caused mainly by volatile sulfur compounds produced by gram-negative bacteria. however, it has recently been found that anaerobic gram-positive bacteria also produce hydrogen sulfide (h 2 s) in ...

introduction: deep periodontal pockets pose a great challenge for nonsurgical periodontal treatment. scaling and root planing (srp) alone may not suffice in cases where surgical therapy cannot be undertaken. various recent studies have suggested the use of antimicrobial photodynamic therapy (apdt) for the management of periodontal infections. the aim of this study was to evaluate the effects of...

nowadays, developements in nanotechnology have leeds an increased application of this newborn technology in cancer treatment. in this study, a stabilized micelle was developed to load hpd in order to be used in photodynamic treatment of cancer in an animal model. to construct micelles, pluronic p-105 was used and stabilized to encapsulate hpd . this process includes a 24 h polymerization in whi...

introduction: the efficiency of routine scaling and root planning is negatively influenced by the tooth anatomy and residual bacteria all possibly affecting the treatment outcomes in future. the present study compared the microbiologic effectiveness of the photodynamic therapy (pdt) as an adjunctive treatment modality for nonsurgical treatment in chronic periodontitis. methods: in this randomiz...

today, use of nanotechnology for cancer therapy is an active field of research. early detection, accurate diagnosis, and individual treatment are the aims which cause nanotechnology as an attractive area for research. among metallic nanomaterials, gold nanostructures have unique properties which make them remarkable candidates for biomedical approaches. surface plasmonic resonance (spr) effect ...
