Patent number: 9694055Abstract: The invention is directed to methods of inducing cell recruitment and tissue regeneration at a target site in a subject. It is also based, in part, on the discovery that a subject's own biologic resources and environmental conditions can be used for in situ tissue regeneration and thereby reduce or eliminate the need for donor cell procurement and ex vivo manipulation of such donor cells. Methods are disclosed for recruitment of a subject's own stem cells to a target region by inducing a sustained positive pressure at a target site, such as the kidney, thereby increasing the number of pluripotent cells capable of differentiating to regenerate the target tissue.Type: GrantFiled: May 11, 2009Date of Patent: July 4, 2017Assignee: Wake Forest University Health SciencesInventors: James Yoo, Sang Jin Lee, Mark Van Dyke, Anthony Atala

Patent number: 8283385Abstract: Reversible switchable surfactants are provided. A surfactant is the salt of an amidine or guanidine: having at least one R group that is a hydrophobic moiety selected from the group consisting of higher aliphatic moiety, higher siloxyl moiety, higher aliphatic/siloxyl moiety, aliphatic/aryl moiety, siloxyl/aryl moiety, and aliphatic/siloxyl/aryl moiety. The other R groups are smaller moieties such as H, C1 to C4 aliphatic or the like. The surfactant is turned on by a gas that liberates hydrogen ions, such as, for example, carbon dioxide, which liberates hydrogen ions in the presence of water. The surfactant is turned off by exposure to a flushing gas and/or heating. When “on” the surfactants are useful to stabilize emulsions, and when “off” they are useful to separate immiscible liquids or a liquid and a solid. The surfactants find uses in polymerization and in the oil industry.Type: GrantFiled: November 15, 2006Date of Patent: October 9, 2012Assignee: Queen's University at KingstonInventor: Philip G.

Patent number: 8211949Abstract: Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.Type: GrantFiled: September 16, 2008Date of Patent: July 3, 2012Assignee: Dow Global Technologies LLCInventors: Pierre T.

Patent number: 7179328Abstract: An aqueous solution for treatment of colored concrete, glazed enamel or porcelain surfaces to increase the coefficient of friction of that surface, whether dry or wet, to about 0.8 without deteriorating the color of the surface comprises about 1.5 to 1.9 wt % of ammonium bifluoride, 1.5 to 3.0 wt % of tri-ethylamine and a wetting agent in water. The degree of change of the color of the surface, treated seven minutes with the solution of the current application, measured by a color meter shows only 0.56 while the result of a commercial solution to increase the frictional coefficient shows 2.22. This means that the color change by the solution of the current application is undetectable by human eyes. Meanwhile, the change by the commercial solution product is detectable.Type: GrantFiled: December 7, 2004Date of Patent: February 20, 2007Inventors: Tae Hoon Kim, Whankoo Kang, Yongkyu Hwang
