Patent number: 11795432Abstract: Embodiments described herein generally relate to passively replacing media in a closed cell expansion system to reduce or prevent the dilution of chemical signaling used to inhibit signaling pathways that keep a cell population in the lag phase of cell growth. To prevent such dilution, active inlet fluid flow to the system may be halted. To replace fluid lost by the system, a bag containing media may be attached to the waste line in replacement of the waste or outlet bag connected thereto. By turning off one or more pumps, media from the replacement bag is added to the system at the rate of evaporation. Chemical signaling dilution may be prevented while conserving system resources. Enhancement of chemical signaling to reduce the lag phase of cell growth may further be accomplished by adding molecules, such as chemical-signaling proteins, from a direct source to the system.Type: GrantFiled: December 20, 2017Date of Patent: October 24, 2023Assignee: Terumo BCT, Inc.Inventor: Brian J.

Patent number: 9814821Abstract: A method for removal of at least a portion of carbon dioxide from an aqueous fluid such as a blood fluid includes placing a first surface of at least one membrane through which carbon dioxide and at least one acid gas other than carbon dioxide can pass in fluid in contact with the fluid. The membrane limits or prevent passage of the fluid therethrough. A carrier or sweep gas including the acid gas other than carbon dioxide is passed over a second surface (which is typically opposite the first surface) of the membrane so that the acid gas other than carbon dioxide can pass through the membrane into the fluid, and carbon dioxide from the fluid can pass from the liquid, through the membrane, and into the sweep gas.Type: GrantFiled: June 15, 2013Date of Patent: November 14, 2017Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: William J.

Patent number: 9568460Abstract: A liquid phase microextraction (LPME) method was developed for the determination of sulfur compounds in crude oils and its fractions (e.g diesel). Wide ranges of sulfur compounds including benzothiophene, dibenzothiophene and their derivatives were used as model compounds for extraction. After extraction, the analyses were performed by gas chromatography equipped with sulfur chemiluminescence detector (GC-SCD). Various experiments conditions influencing the extraction such as extraction times, extraction solvents, solvent volume and quantitative parameters were optimized to achieve higher extraction efficiency and high accuracy. The optimized conditions were applied to the determination of sulfur compounds in crude oil and diesel.Type: GrantFiled: August 28, 2014Date of Patent: February 14, 2017Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Basheer Chanbasha, Ibrahim Mohammed Al-Zahrani, Than Htun
