Summary of "Amphiphilic polymers based on polyoxazoline as relevant nanovectors for photodynamic therapy."

An amphiphilic polymer (CmPOX) based on poly(2-methyl-2-oxazoline) linked to a hydrophobic part composed of an aliphatic chain ending with a photo-active coumarin group has been synthesized. It exhibits the ability of forming small polymeric self-assemblies, typically of ca. 10 nm in size, which were characterized by TEM, cryo-TEM and DLS. The nanocarriers were further formulated to yield photo-crosslinked systems by dimerization of coumarin units of coumarin-functionalized poly(methyl methacrylate) (CmPMMA) and CmPOX. The formed vectors were used to encapsulate Pheophorbide a, a known photosensitizer for photodynamic therapy. Cytotoxicity as well as phototoxicity experiments performed in vitro on human tumor cells revealed the great potential of these nanovectors for photodynamic therapy.

Medical and Biotech [MESH] Definitions

The purified component of HEMATOPORPHYRIN DERIVATIVE, it consists of a mixture of oligomeric porphyrins. It is used in photodynamic therapy (HEMATOPORPHYRIN PHOTORADIATION); to treat malignant lesions with visible light and experimentally as an antiviral agent. It is the first drug to be approved in the use of PHOTODYNAMIC THERAPY in the United States.

The enhancement of physical, cognitive, emotional and social skills so an individual may participate in chosen activities. Recreational modalities are used in designed intervention strategies, incorporating individual's interests to make the therapy process meaningful and relevant.

A complex mixture of monomeric and aggregated porphyrins used in the photodynamic therapy of tumors (HEMATOPORPHYRIN PHOTORADIATION). A purified component of this mixture is known as DIHEMATOPORPHYRIN ETHER.

A direct form of psychotherapy based on the interpretation of situations (cognitive structure of experiences) that determine how an individual feels and behaves. It is based on the premise that cognition, the process of acquiring knowledge and forming beliefs, is a primary determinant of mood and behavior. The therapy uses behavioral and verbal techniques to identify and correct negative thinking that is at the root of the aberrant behavior.

The treatment of immune system diseases by deliberate infestation with helminths. This therapy is partly based on the HYGIENE HYPOTHESIS which states that the absence of parasites increases immune dysregulation because of the lack of stimulation of REGULATORY T-CELLS.
