摘要:
The present invention is directed to a covalently crosslinked hydrogel comprising the strain-promoted reaction product of an 8-member cycloalkyne functionalized polyalkylene glycol and a multi-arm glycerol exytholate triazide and methods for making them. Because the precursor materials can be manipulated without causing crosslinking, provided the strain threshold is not reached, these hydrogels permit mechanical control over when (and where) cross linking occurs and are easier to use than prior strain-activated or temperature-activated systems. These novel hydrogels do not require a catalyst to cross link, thus avoiding the biocompatibility problems common to many catalysts. Nor is the crosslinking process affected by the presence of catalysts or other substances, which have interfered with crosslinking in known strain induced hydrogels. Because of their crosslinking reaction kinetics, these novel hydrogels can encapsulate and transport highly sensitive cells and other biological additives and have no known toxic byproducts.

This invention is an improved method and device for treating varicose veins 200 or the greater saphenous vein 202. The method comprises the use of infrared laser radiation in the region of 1.2 to 1.8 um in a manner from inside the vessel 200 or 202 such that the endothelial cells of the vessel wall 704 are damaged and collagen fibers in the vessel wall 704 are heated to the point where they permanently contract, the vessel 200 or 202 is occluded and ultimately resorbed . The device includes a laser 102 delivered via a fiber optic catheter 300 that may have frosted or diffusing fiber tips 308. A motorized pull back device 104 is used, and a thermal sensor 600 may be used to help control the power required to maintain the proper treatment temperature.
摘要:
Disclosed are compositions and methods related to NEDD4L, a ubiquitin ligase, and hypertension as well as viral budding. A systematic search for genetic polymorphism was conducted by resequencing exon and intron boundaries in human genomic DNA. Isoforms encoding a Ca 2+ -dependent lipid binding C2 domain at the N-terminus of NEDD4L were identified. Additional isoforms lacing the C a+ - dependent lipid binding C2 domain were also identified. A common polymorphism was identified, Variant 13, with either G (70%) or A (30%) as the last nucleotide of exon 1, which effects splice site function and formation of the C a+ -dependent lipid binding C2 domain. Identified isoforms are present in both kidney and adrenal samples.
摘要:
A high throughput method for screening a biological sample for unknown viruses, which method comprises: (a) subjecting DNA from the sample to PCR amplication conditions using simultaneously multiple pairs of degenerate primers, wherein each primer binds a sequence that is conserved across members of a family of viruses and each pair of primers selectively directs amplication of sequence of said family; (b) sequencing PCR product obtained in step (a); and (c) comparing the sequence of the PCR product with the sequences in at least one database comprising viral sequences to determine whether the sequence is present in, or absent from, the database, wherein absence of the sequence from the database suggests that the sequence may be from an unknown virus.

The invention relates to non-flammable, thermoplastic moulded materials containing (A) at least one polyphenylene ether, (B) at least one vinyl aromatic polymer, and (C) at least one flame-proofing agent. Said materials are characterised in that they also comprise (D) and as the non-drip agent a high-molecular polymer based on acrylamide with a viscosity approximately of above 1.5 mPas, measured in an aqueous solution of 0.1 % at 25 DEG C. The invention also relates to the use of said materials in the production of fibres, sheets and moulded structures.
摘要:
Methods for identifying and monitoring increased or decreased levels of inducible nitric oxide synthase in biological samples are provided. A collection device for detecting inducible nitric oxide synthase in biological samples is also provided. Detection of inducible nitric oxide synthase is useful in the diagnosis of inflammatory responses such as infections mediated by bacteria, yeast or viruses, transplant rejection, rheumatoid arthritis, interstitial cystitis and cancer.
