  • Publication number: 20130315948
    Abstract: The present invention relates to a new process for producing a doped synthetic monodispersed hematin anhydride (HA) crystals useful as a slow release vehicle and immune modulator. As the preparation comprises embedded in the crystals one or more antigens and/or one or more biologically active entities, the preparation can be useful in numerous medical indications such as vaccine or any therapy where it is desired that a biologically active entity maintains its activity over time due to its slow-release. The process comprises the steps of (i) providing a substantially pure iron(III) protoporphyrin-IX, in solution in an alkaline solution substantially free of oxygen (ii) adjusting the pH of the solution to an acidic pH of between about 4.0, by slowly adding a medium strong organic acid, (iii) during step b) above, adding one or more antigens and/or one or entities having a biological activity, at a pH of about 5.0.

  • Publication number: 20130300483
    Abstract: Time-Mode Signal Processing (TMSP) offers a means for offsetting some of the challenges for analog circuit designs when exploiting CMOS circuit processes designed for digital applications. It would therefore be beneficial to provide a digital method for the storage, addition and subtraction of Time-Mode variables as these offer significant benefit to providing TMSP techniques and expanding their exploitation within devices, systems, and applications. Whilst driven by CMOS process challenges the TM circuits outlined may exploit essentially any digital circuit technology since they are based upon delay. The inventors present an approach to TM variables wherein a switched delay unit is exploited and adopted such that the instantaneous phase difference between two rising signal edges can be latched and used to perform various arithmetic operations. Beneficially, the technique allows analog sampled-data signal processing to be implemented within digital circuitry.

  • Patent number: 8565281
    Abstract: Strongly confined semiconductor quantum dots theoretically offer for broadband and continuous tunability of their emitting wavelength based upon simply varying the particle size. However, prior art consistently has demonstrated a lower particle size limit below which optical gain cannot be achieved, for example 2.3 nm for CdSe in toluene. As such the prior art points to combinations of alternative materials and host media as the route to achieving the goal of broadband emission sources using quantum dots. However, according to the invention optical gain can be achieved in quantum dots below these previous experimental limits by resonantly pumping the quantum dots to a specific excitonic state, i.e. electron position relative to the quantum dot, such that the multiexcitonic interferences are minimized. Using this approach optical gain in CdSe of R=2.1 nm and 1.5 nm has been demonstrated in the yellow/amber region of the visible spectrum.

  • Patent number: 8563395
    Abstract: Amongst the candidates for very high efficiency solid state lights sources and full solar spectrum solar cells are devices based upon InGaN nanowires. Additionally these nanowires typically require heterostructures, quantum dots, etc which all place requirements for these structures to be grown with relatively few defects. Further manufacturing requirements demand reproducible nanowire diameter, length etc to allow these nanowires to be embedded within device structures. Additionally flexibility according to the device design requires that the nanowire at the substrate may be either InN or GaN. According to the invention a method of growing relatively defect free nanowires and associated structures for group III—nitrides is presented without the requirement for foreign metal catalysts and overcoming the non-uniform growth of prior art non-catalyst growth techniques. The technique also allows for unique dot-within-a-dot nanowire structures.

  • Patent number: 8563520
    Abstract: The present invention relates to methods to treat glaucoma and glaucoma-related conditions through the regulation of changes in gene expression that are mediated by high intraocular pressure or ?2 macroglobulin administration. Glaucoma, retinal ganglion cell (RGC) death and chronic ocular hypertension are treated using pharmaceutical compositions which comprise substances that inhibit the expression or activity of intraocular pressure-regulated early genes (IPREGs) or their gene products that are up-regulated by high intraocular pressure or ?2 macroglobulin administration and/or which increase the expression or activity of IPREGs or their gene products that are down-regulated by high intraocular pressure or ?2 macroglobulin administration. The invention also relates to methods of identifying an IPREG and methods to test for chronic ocular degeneration and the onset of RGC stress in an individual by measuring the expression level of IPREG proteins.

  • Publication number: 20130255361
    Abstract: In most cancers, a significant factor in a poor outcome for the individual cancer victim is metastatic disease, i.e., dissemination of tumour cells to other parts of the human body via the circulation, such as distant organs, and their subsequent proliferation therein to form multiple other cancer tumours. The presence of circulating tumour cells, or CTCs, represents a vital intermediate step in this process and variations of a few CTCs within blood samples containing tens of billions of cells may denote the outcome for a patient or impact the cancer treatment regimen. At present no low cost field deployable technique for filtering CTCs exists. According to embodiments of the invention micro-machined filters with high aspect ratio, with and without, functionalization are employed to perform multi-parameter filtering for CTCs based upon compatibility with low cost semiconductor processes within multiple materials including silicon, polymers and silicon carbide.

  • Publication number: 20130236153
    Abstract: Optical fibers and optical fiber tapers have application within many optical systems and optical devices. To date manufacturing such fibers and fiber tapers has been restricted to drawing constant diameter fibers in gravity driven processes and symmetric tapers through pulling with localized heating. However, it would be beneficial to be able to generate arbitrary profiles when pulling an optical fiber into a fiber taper allowing an initial uniform section, reducing transition, wire section, increasing transition and final uniform section.
