  • Patent number: 8238388
    Abstract: A tunable laser device (1) comprises integrally formed first and second ridge waveguides (5, 6). A longitudinally extending ridge (12) defines first and second light guiding regions (19, 20) of the first and second waveguides (5, 6) A plurality of first and second slots (27, 28) extending laterally in the ridge (12) adjacent the first and second waveguides (5, 6), produce first and second mirror loss spectra of the respective first and second waveguides (5, 6) with minimum peak values at respective first and second wavelength values. The spacing between the second slots (28) is different to that between the first slots (27) so that with one exception the minimum peak values of the first and second mirror loss spectrum occur at different wavelength values. The first and second waveguides (5, 6) are independently pumped with variable currents to selectively vary the common wavelength at which the minimum peak values of the first and second mirror loss spectra occur to produce Vernier tuning of the device.

  • Patent number: 8153426
    Abstract: The invention relates to a method for the preparation of efficient antigen-presenting human ?? T cells, to the ?? T cells prepared by such a method, and to their use in immunotherapy, vaccination, vaccine development and diagnostics. Similar to dendritic cells (DCs) in potency and efficacy, these human ?? T cells process antigens and present antigenic peptides to ?? T cells and induce antigen-specific responses (proliferation and differentiation) in naïve ?? T cells. ?? T cells are easily purified from peripheral blood, acquire “maturation” status (expression of essential adhesion, co-stimulatory and major histocompatibility complex molecules) within 1 day of in vitro culture under stimulation and induce strong primary and secondary T helper cell and cytotoxic T cell responses. The ?? T cells may be used in a method of treatment of tumors or chronic or recurrent infectious diseases, in identification of novel tumor or pathogen-derived antigens, and in the diagnosis of the immune competence of a patient.

  • Patent number: 8137409
    Abstract: A method of installing a transcutaneous prosthesis which includes a first component, a second component adapted for location between the bone and the skin, the second component having a surface treatment for stimulation of fibroblastic cell proliferation and attachment of epithelial cells and a third component adapted for location to extend from the skin surface and the third component having an outer surface. The outer surface of the third component has a surface energy that is lower than a surface energy of at least the first component and which is low enough to deter bacterial adhesion. The method includes attaching the first component to a bone such that a transition from the second component to the third component is essentially at the surface of the skin and the third component extends from the skin surface when the first component is attached to a bone.

  • Patent number: 8093046
    Abstract: The invention provides a recombinant multi-functional chimera of CVN and 12p1. Chimeras of CVN and 12p1 present a model for targeting gp120 at two discrete sites, by two different modes of inhibition and with increasing potency versus either component alone. A chimera of the invention combines the high affinity suppression of viral activity by CVN with the allosteric suppression of viral envelope binding to both CD4 and co-receptor by 12p1.

  • Publication number: 20110226610
    Abstract: Inventors have developed a chromophore (nitrodibenzylfuranyl, or NBDF) for ultra efficient uncaging of a caged substrate (e.g., an organic molecule such as, for example, an amino acid, a biological molecules, such as, for example, second messengers inside cells). Photolysis of a NBDF derivative of EGTA (i.e. caged calcium) is about 50 times more efficient than others calcium cages (the quantum yield of photolysis is 0.6 and the extinction coefficient is 18,400. NDBF-EGTA has a 2-photon cross section of about 0.3-0.6 GM).
