摘要:
Methods for the conditioning of bioprosthetic material employ bovine pericardial membrane. A laser directed at the fibrous surface of the membrane and moved relative thereto reduces the thickness of the membrane to a specific uniform thickness and smoothes the surface. The wavelength, power and pulse rate of the laser are selected which will smooth the fibrous surface as well as ablate the surface to the appropriate thickness. Alternatively, a dermatome is used to remove a layer of material from the fibrous surface of the membrane. Thinning may also employ compression. Stepwise compression with cross-linking to stabilize the membrane is used to avoid damaging the membrane through inelastic compression. Rather, the membrane is bound in the elastic compressed state through addition cross-linking. The foregoing several thinning techniques may be employed together to achieve strong thin membranes.

Provided is a flavor modifying composition including a blend of a water soluble filler including plant fibers; and at least one sucrose substitute of natural source, wherein said flavor modifying composition includes at least 90% w/w of the filler, the amount being determined when said composition is in dry form; and said flavor modifying composition is water soluble. The flavor modifying composition is particularly effective in enhancing sweet taste and/or aroma of a product. Further provided are products including the flavor modifying composition.

摘要:
A system and method for using social tools, such as social media, to engage one or more members of a healthcare ecosystem that includes: tools for enabling sharing content from an identified source, posting of content from an anonymous source, anonymously linking a member to one or more third party stakeholders (health insurance companies, physicians, organizations, employers), and one or more contests and rewards for providing incentives for behaviors promoted by third party stakeholders, and a reporting tool for use by the third party stakeholders for assessing the effectiveness of the contests and rewards, both on the group and individual level, to achieving those behaviors. All of this is provided within a framework that is available on personal computers, tables or mobile phones.
