Abstract:
Systems and methods for optical sectioning microscopy with structured illumination are provided. A light source generates a light beam with a spatial pattern for successively illuminating a sample at each phase of a plurality of phases. A detector detects a first set of images of the sample at a first axial resolution and a first lateral resolution, each image being associated with a respective phase of the plurality of phases of the illumination. A processor processes the first set of images to generate an enhanced sectioned image of the sample. More specifically, the processor generates data representing a second set of images at a second axial resolution greater than the first axial resolution; and subsequently, performs spectral analysis on the data representing the second set of images to form data representing the enhanced sectioned image of the sample at a second lateral resolution greater than the first lateral resolution.

In particular, the present invention provides metallic nanoparticles (e.g. gold nanoparticles) that are encapsulated in biologically important carbohydrate molecules, such as sugars, sugar derivatives, P-blood group antigens and analogues thereof. The present invention also provides methods of employing these carbohydrate encapsulated nanoparticles in diagnostic and therapeutic applications.
Abstract:
A method for fabricating organic optoelectronics multi-layer devices is disclosed. A polydimethylsiloxane (PDMS) surface is pretreated with an organic solvent and used to directly form a uniform optoelectrical thin-film from organic solution by spin coating. The optoelectrical thin-film films that are formed on the PDMS surface are easily transferable to any substrate by a slight, externally applied force for providing conformal contact with a target substrate and thermal annealing, depending on the polymers to be transferred. Pretreatment of the PDMS surface with the organic solvent combined with a dry transfer process provides an easier way to cascade polymer architecture fabrication. In addition, the method increases the performance of various types of organic photo electronics, and permits an extension of the types of research that can be performed in the field of photo electronics.
Abstract:
The present disclosure provides methods for increasing the lipopolysaccharide-induced secretion of IL-1 by macrophages, for increasing serum levels of IL-1 in a mammal, for increasing the serum level of IL-1 receptor antagonist (IL-1Ra) in a mammal, for increasing the secretion of IL-1 by a monocyte, for increasing the secretion of IL-1Ra by a monocyte, for increasing the secretion of IL-1Ra by a macrophage, for increasing expression of TLR4 on the surface of a macrophage, for increasing expression of CD14 on the surface of macrophage, for increasing the uptake and clearance of lipopolysaccharide (LPS) by a LPS-stimulated macrophage, and for increasing lipopolysaccharide (LPS)-stimulated activation of at least one of ERK, JNK, and p38 in a macrophage. The methods of the disclosure involve the administration to mammals and immune cells of a fucose-containing glycoprotein fraction from Ganoderma lucidum.
Abstract:
A dye compound is described, which is expressed by formula (I): wherein A1, A2 and A3 each independently represent a substituted or unsubstituted 1,4-phenylene or 2,5-thiophene group, and B1 and B2 each independently represent a substituted or unsubstituted aryl group.

Abstract:
The present invention features an isolated nucleic acid that includes a mutant DNA encoding a Candida rugosa lipase, wherein the mutant DNA is 80% identical to a wild-type DNA encoding the Candida rugosa lipase, and includes at least 12 (e.g., 13, 15, 17, or all) universal serine codons corresponding to CTG codons in the wild-type DNA. Each of the universal serine codons, independently, is TCT, TCC, TCA, TCG, AGT, or AGC. The Candida rugosa lipase can be Candida rugosa lipase 1, 2, 3, 4, 5, or 8.
