Abstract:
A browser-based tool is provided that loads a Webpage, accesses the document object model (DOM) of the page, collects information about the page structure and parses the page, determines through the use of heuristics such factors as how much text is found on the page and the like, produces statistical breakdown of the page, and calculates a score based on performance of the page. Key to the operation of the invention is the ability to observe operation of the Webpage as it actually loads in real time, scoring the page for several of various performance factors, and producing a combined score for the various factors.

Abstract:
Methods, systems, assemblies, computer program products and devices produce hyperpolarized gas by: (a) providing a plurality of cells (30), each having a respective quantity of target gas held therein; (b) polarizing the target gas in and/or from the cells in a desired order to provide separate batches of polarized gas; and (c) repolarizing the previously polarized target gas held in least one of the cells when the polarization level falls below a predetermined value.
Abstract:
A treatment for bioprosthetic tissue used in implants or for assembled bioprosthetic heart valves to reduce in vivo calcification is disclosed. The method includes preconditioning, pre-stressing, or pre-damaging fixed bioprosthetic tissue in a manner that mimics the damage associated with post-implant use, while, and/or subsequently applying a calcification mitigant such as a capping agent or a linking agent to the damaged tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the damage process (service stress) and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. The linking agent will act as an elastic reinforcement or shock-absorbing spring element in the tissue structure at the site of damage from the pre-stressing. In one method, tissue leaflets in assembled bioprosthetic heart valves are preconditioned by simulating actual flow conditions for a predetermined number of cycles, during or after which the valve is exposed to the capping agent.
Abstract:
A treatment for bioprosthetic tissue used in implants or for assembled bioprosthetic heart valves to reduce in vivo calcification. The method includes applying a calcification mitigant such as a capping agent or an antioxidant to the tissue to specifically inhibit oxidation in tissue. Also, the method can be used to inhibit oxidation in dehydrated tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the oxidation and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. In one method, tissue leaflets in assembled bioprosthetic heart valves are pretreated with an aldehyde capping agent prior to dehydration and sterilization.

Abstract:
A method of treating a biological tissue that enables dry storage of said tissue is disclosed. In one embodiment, the method comprises contacting the biological tissue with a non-aqueous treatment solution comprising a polyhydric alcohol and a C1-C3 alcohol and removing a portion of the treatment solution from the solution-treated biological tissue. Also disclosed is biological tissue prepared using the above process and prosthetic devices made with such tissue.
