摘要:
A polarimetric imaging system employs a pixel pitch matched filter for use within, for example, a 2 by 2 pixel neighborhood, in which one pixel samples the scene via a 0 degree polarization filter and a second pixel samples the scene via a 45 degree polarization filter. The remaining two pixels record the intensity of the light within the 2 by 2 neighborhoods. The polarization filters employ organic materials such as polymers or metallic materials that are patterned and etched using reactive ion etching (RIE) or other appropriate etching technique in order to create 14 micron or smaller circular (or square) periodic structures that are patterned into polarization thin films that are deposited on an imaging sensor that includes a processor that computes from the polarization-filtered inputs the first three Stokes parameters in real-time.
摘要:
The present invention pertains to methods related to cloning nucleic acids from biological samples, particularly pathological tissue samples. This method includes hybridizing a population of oligonucleotide sequence probes comprising degenerate sequence tags to a fixed tissue, isolating the hybridized oligonucleotide sequence probes and amplifying the sequence tags in the hybridized oligonucleotide sequence probes. This method can be utilized to identify genes associated with disease and to quantitate the expression of disease-related transcripts. The method can also be used to identify truncated mRNAs.
摘要:
Methods of treating autoimmune disorders, coronary artery disease, allergy symptoms, allograft rejection sepsis/toxic shock are disclosed. Some methods comprise administering one or more regulatory compositions to activate the T suppressor cells by increasing the acetylation level and/or protein level of FOXP3 in combination with a T suppressor stimulus and/or an antigen. Some methods comprise administering one or more regulatory compositions to activate the T suppressor cells by increasing the acetylation level and/or protein level of FOXP3. Some methods comprise administering soluble GITR or antibodies that bind to GITR ligand. Methods of treating cancer, infectious diseases, and immune deficiency are also disclosed as are vaccination methods. The methods comprise administering one or more regulatory compositions to inactivate the T suppressor cells by reducing the acetylation level and/or protein level of FOXP3. Improved vaccines and vaccination methods are disclosed. Methods of identifying compounds that are useful to modulate acetylation level and/or protein level of FOXP3 and treat diseases are disclosed.

The present invention relates to compositions and methods for modulating the expression and/or activity of PTEN in T cells, regulatory T cells, and CD4 T cells. The manipulation of PTEN provides a means for regulating an immune response.
摘要:
Methods for the stabilization of microtubules involved in axonal transport are disclosed. The methods employing compounds which functionally substitute for microtubule binding protein tau are useful, inter alia, in the treatment of neurodegenerative diseases or tauopathies. Microtubule stabilizing compounds are useful for the treatment of neurodegenerative diseases, as well as schizophrenia and other mental disorders that are characterized by disruption of maintain neuronal intracellular transport, neurite architecture, or neuronal migration.
