  • Patent number: 9067052
    Abstract: Transcranial magnetic stimulation (TMS) is a remarkable tool for probing the brain. However, it is still unclear why specific regions in the cortex are excitable by TMS while others are not. This invention provides methods and tools for the design of efficient magnetic stimulators. Such stimulators can excite neuronal networks that were not sensitive to stimulation until now. Stimulation can be carried out both in-vitro and in-vivo. Novel systems and techniques of this invention will enable both treatment and diagnostics by stimulating regions of the brain or neuronal assemblies that were previously unaffected by TMS.

  • Patent number: 7897840
    Abstract: The present invention provides transgenic plants transformed with exogenous nucleic acid encoding a Dunaliella salt-inducible or salt-responsive protein selected from the group consisting of eukaryotic initiation factor 3 (eIF3) subunit, NADPH dependent quinone reductase (QOR), aldo-keto reductase (AKR), bifunctional aspartate kinase-homoserine reductase (AK-HSD) and mitochondrial import membrane translocase subunit (TIM9), or a fragment, homolog or variant thereof. The transgenic plants have increased tolerance to salt as compared to corresponding non-transgenic plants.

  • Publication number: 20110006674
    Abstract: A method for fabrication of substrate having a nano-scale surface roughness is presented. The method comprises: patterning a surface of a substrate to create an array of spaced-apart regions of a light sensitive material; applying a controllable etching to the patterned surface, said controllable etching being of a predetermined duration selected so as to form a pattern with nano-scale features; and removing the light sensitive material, thereby creating a structure with the nano-scale surface roughness. Silanizing such nano-scale roughness surface with hydrophobic molecules results in the creation of super-hydrophobic properties characterized by both a large contact angle and a large tilting angle. Also, deposition of a photo-active material on the nano-scale roughness surface results in a photocathode with enhanced photoemission yield. This method also provides for fabrication of a photocathode insensitive to polarization of incident light.

  • Publication number: 20080279878
    Abstract: The present invention provides improved vaccines comprising an isolated viral antigenic peptide and a synthetic peptide derived from a T cell epitope of HSP60. The invention includes mixtures where the peptide serves as an adjuvant as well as conjugates where the peptide is covalently linked to the viral antigen. The known synthetic peptide carrier, p458, provides significantly improved immunogenicity for synthetic viral epitopes and analogs. Ec27 is a novel peptide derived from HSP60 which increases the immunogenicity substantially of the viral antigen both as a mixture or a covalent conjugate. Some of the isolated viral epitopes are novel and are claimed for diagnostic as well as therapeutic or prophylactic uses.
