  • Patent number: 7381404
    Abstract: The present invention relates to altering the physical and/or chemical properties of at least part of at least one tissue in the eye. In a specific embodiment, it relates to the treatment of any eye disorder, although in particular embodiments the individual has a thickened Bruch's membrane. An activating energy source is utilized to effect a controlled diffusion enhancement and/or degradation of Bruch's membrane that enables improved diffusional transport between the choroid and retina. The individual is administered an inactivated diffusion-enhancing molecule that becomes associated with the membrane, which is then precisely exposed to an activating energy source, such as light or ultrasound.

  • Patent number: 7348135
    Abstract: An assay for assessing the permeability of mitochondrial membranes is provided. The assay is based on enzymatic reactions that produce a detectable signal in the presence of intra-mitochondrial compounds. In some embodiments, the intra-mitochondrial compounds may be reduced and/or oxidized nicotinamide adenine dinucleotides (i.e., NADH and NAD+, respectively). The assay may optionally be provided in the form of a kit, and may further be useful in the discovery and interrogation of compounds that may serve to inhibit pathologic increase in mitochondrial membrane permeability, which is associated with numerous and varied mammalian disease.

  • Patent number: 7335286
    Abstract: The invention relates to measuring the concentration of analytes with the aid of an oxidase in an immersion sensor situated in a fluid or in a matrix containing fluid. Oxygen diffuses into the enzyme layer from within, from a gas-filled space connected to the atmosphere and/or to an oxygen reservoir. This enables oxygen saturation of the oxidase in a low-oxygen or oxygen-free medium and/or at high analyte concentrations. The analyte diffuses into the enzyme layer in a channel or a number of channels which contain(s) water and limit(s) diffusion, wherein the channel/channels on the surface of the sensor is/are filled with a protein-impermeable, hydrophilic matrix. By increasing the channel cross-section on the surface of the sensor and/or by connecting the channel/channels to a protein-impermeable, porous, hydrophilic layer on the surface of the sensor, the effect of outer deposits on the diffusion resistance of the analyte is reduced.
