52 results about "Abnormal blood vessels" patented technology

Abnormal blood vessels are usually found in tumorous tissue. It is because, tumors grow very fast and its blood vessels as well. Because of this enhanced sped of growth blood vessels are not able to maturate and they stay abnormal.

Transcutaneous photodynamic treatment of targeted cells

The present invention is drawn to methods and compounds for photodynamic therapy (PDT) of a target tissue or compositions in a mammalian subject, using a light source that preferably transmits light to a treatment site transcutaneously. The method provides for administering to the subject a therapeutically effective amount of a targeted substance, which is either a targeted photosensitizing agent, or a photosensitizing agent delivery system, or a targeted prodrug. This targeted substance preferably selectively binds to the target tissue. Light at a wavelength or waveband corresponding to that which is absorbed by the targeted substance is then administered. The light intensity is relatively low, but a high total fluence is employed to ensure the activation of the targeted photosensitizing agent or targeted prodrug product. Transcutaneous PDT is useful in the treatment of specifically selected target tissues, such as vascular endothelial tissue, the abnormal vascular walls of tumors, solid tumors of the head and neck, tumors of the gastrointestinal tract, tumors of the liver, tumors of the breast, tumors of the prostate, tumors of the lung, nonsolid tumors, malignant cells of the hematopoietic and lymphoid tissue and other lesions in the vascular system or bone marrow, and tissue or cells related to autoimmune and inflammatory disease.

Methods and Compositions for Treating Conditions Involving Abnormal Angiogenesis

The present invention features methods and compositions for preventing, reducing, or treating hypoxia and, pathological disorders involving abnormal angiogenesis. Thus, the present invention is useful for treating, reducing, or preventing ischermic conditions (characterized by a reduced blood flow or reduced angiogenesis, e.g., a myocardial infarct) and hypervascular conditions (characterized by excessive angiogenesis, e.g., cancer). Where an increase in angiogenesis is desired, the mammal being treated for an ischermic condition is provided with Related Transcriptional Enhancer Factor-1 (RTEF-1; as a recombinant polypeptide or as an expression vector) sufficient to increase expression of VEGF, FGFR, or COX-2. This results in a concomitant increase in angio-genesis. Conversely, a mammal being treated for a hypervascular condition is administered a composition that reduces the levels of RTEF-1, thereby reducing the expression of VEGF, FGFR, or COX-2, which results in a decrease in angiogenesis. Also disclosed are screening methods that make use of RTEF-1 for the identification of novel therapeutics for the treatment, prevention, or reduction of pathological disorders involving hypoxia or abnormal angiogenesis, namely, ischernic or hypervascular conditions.
