  • Publication number: 20070129615
    Abstract: The present invention relates to probe apparatuses and component combinations thereof that are used to recognize possibly abnormal living tissue using a detected early increase in microvascular blood supply and corresponding applications. In one embodiment there is disclosed an apparatus that emits broadband light obtained from a light source onto microvasculature of tissue disposed within a human body and receives interacted light that is obtained from interaction of the broadband light with the microvasculature for transmission to a receiver. Different further embodiments include combinations of optical fibers, polarizers and lenses that assist in the selection of a predetermined depth profile of interacted light. In another embodiment, a kit apparatus is described that has various probe tips and/or light transmission elements that provide for various combinations of predetermined depth profiles of interacted light.

  • Publication number: 20060155178
    Abstract: A method of examining a sample includes measuring, as function of wavelength of light elastically scattered from the sample, at least 2 properties, selected from the group consisting of scattering angle theta of the light, scattering angle phi of the light, and polarization of the light. The scattering angle theta is an angle between backward direction and direction of propagation of the light, and scattering angle phi is an angle between incident light polarization and projection of direction of the light propagation onto a plane in which incident electric field oscillates.

  • Publication number: 20050261249
    Abstract: A method and composition for of treating cancer, and in particular, for arresting the progression of a solid or primary cancer to a more invasive, metastatic state, are disclosed. The composition includes a substantially uncharged antisense compound (i) having a nuclease-resistant backbone, (ii) capable of uptake by target cancer cells in the subject, (iii) containing between 10-40 nucleotide bases, and (iv) having a base sequence effective to hybridize to a region of processed or preprocessed human SNAIL RNA transcript. The compound, when administered to the subject, is effective to form within target cancer cells in the subject, a base-paired heteroduplex structure composed of human SNAIL RNA transcript and the oligonucleotide compound, where this structure is characterized by a Tm of dissociation of at least 45° C.
