Infectious pneumonia is a major cause of morbidity/mortality, mainly due to the increasing rate of microorganisms resistant to antibiotics. Photodynamic Inactivation (PDI) is emerging as a promising approach, as effects ...

Photodynamic Therapy (PDT) is known to be limited to applications in large volume tumours due to its limited penetration. Therefore, the PDT with the Luzitin® photossensitizer as well as a combination of PDT and laser ...

Photodynamic Therapy (PDT) has been helping medicine in treatment infectious diseases and tumors. PDT's principle is based on a photosensitizer (PS) that is photoactivated by light at specific wavelength which generates ...

The Photodynamic Antimicrobial Chemotherapy (PACT) has shown that is a promising alternative for buccal disinfection. The objective of this in situ work is to investigate the antimicrobial effect of photodynamic therapy ...

Nonmelanoma skin cancer is the most frequent disease in the world population and it is becoming a public health problem. Due to this fact, new technologies are being tested for the treatment of this disease. Photodynamic ...

In Brazil there was an increase of post-surgical infections by rapidly growing mycobacteria, mainly Mycobacterium massiliense, leading the Agency for Sanitary Surveillance (ANVISA) to establish standards for the mandatory ...

The photodynamic inactivation (PDI), used for biological control of microorganisms, involves the action of a photosensitizer (PS), activated by visible light, in order to oxidize organic substrates, resulting in cytotoxic ...

Photodynamic therapy (PDT) is a modality for treatment of tumors, and uses a combination of a drug (photosensitizer) and light in the presence of the molecular oxygen to selectively damage target tissue. In the absent of ...

Demineralization and caries are often present in patients with orthodontic braces due to the increased accumulation of dental biofilm containing Streptococcus mutans, which produces acids that attack the tooth surface. ...
