20110250143 | PROCESS FOR PREPARING CHLORINS AND THEIR PHARMACEUTICAL USES - The disclosed subject matter includes methods of preparation, properties, pharmaceutical compositions and methods of therapy of sulfonated chlorins and bacterioclorins designed for the photodynamic therapy (PDT) of hyperproliferative tissues such as tumors, hyperproliferative blood vessels and other disorders or abnormalities that are responsive to PDT. In particular, the economical large-scale synthesis of stable chlorins and bacteriochlorins is described. Their properties were tailored to meet those of ideal photosensitizers for PDT. In another embodiment, pharmaceutical compositions and methods of therapy for systemic administration are provided. In a further embodiment, pharmaceutical compositions and methods of therapy for topical administration are also provided. Further provided is a method of labeling a target tissue and providing an image of that tissue by fluorescence of magnetic resonance imaging. | 10-13-2011 |
20140046246 | DEVICE FOR EFFICIENT DELIVERY OF COMPOUNDS TO OR THROUGH THE SKIN OR BIOLOGICAL BARRIERS, USING LIGHT-ABSORBING THIN FILMS - This invention refers to a device capable of rapidly and efficiently converting the energy in a laser pulse into a high-impulse broadband pressure wave and to its applications in the transient permeabilization of a biological membrane, including the outer layers of the skin, without causing damage or discomfort. A method to deliver drugs and biologically active compounds to or through the skin, or biological barriers, with this device is also disclosed. | 02-13-2014 |

20140056250 | Distributed Control of Channel Selection in a Communication System - Mechanisms for enabling distributed access control are disclosed. At least one communication channel is selected for wireless communication by a device by a selection procedure where interference impact of at least one communication channel on at least one interfered node is determined, an overall interference effect is formed, and a set of feasible communication channels is selected based on comparison of the overall interference effect to communication channel capacity. At least one communication channel can be selected from the selected set of feasible communication channels based on transmission collision information, a ratio of capacity of interfered transmissions and capacity of interference-free transmissions, usage history of the feasible communication channels, and fairness of communication channel selection. Information can be communicated to at least one device from a plurality of access nodes. | 02-27-2014 |
