Patent number: 7645424Abstract: A reagent cuvette has a first chamber with an inspection part and a socket, and a second chamber. The socket has four spikes at its base. Both chambers are sealed with a membrane. At the point-of-care the foil membrane of the first chamber is peeled away by the therapist (typically general practitioner doctor). A sample, such as blood, is added to the chamber using a pipette or other device to provide a verifiable quantity of sample. This provides a mixture of a buffer reagent supplied in the chamber and the sample injected into the inspection chamber at the point of care. The chamber is then inserted into the socket by gently pressing it down so that its foil membrane is broken by the spikes. This causes the starter reagent to drop down from within the second chamber into the inspection part of the first chamber. The inspection part is then inserted into an optical inspection instrument for analysis of the two reagents and the sample mixed together.Type: GrantFiled: May 16, 2006Date of Patent: January 12, 2010Inventor: Michael O'Donovan

Publication number: 20090298163Abstract: A multilayered cell culture apparatus for the culturing of cells is disclosed. The cell culture apparatus includes a unitary flask body including a rigid upper and lower surface, connected by side walls. The cell growth apparatus comprises multiple cell growth chambers stacked in vertical alignment and orientation within the unitary flask body. The stacked chambers are held in position by unitary connecting columns that run through each cell growth chamber and terminate at the rigid upper and lower surfaces of the apparatus. The cell growth chambers are separated by tracheal spaces that allow air from the external environment to contact the cell growth surface of each individual cell growth chamber.Type: ApplicationFiled: September 16, 2008Publication date: December 3, 2009Inventors: Scott M. Bennett, Henry J. Cattadoris, David A. Kenney, Gregory R. Martin, Allison J. Tanner, Joseph C. Wall

Patent number: 7598074Abstract: A reaction tank (5) holds crushed cells comprising a pellicle of Bacillus midousuji cultured in the presence of a chlorinated aromatic compound such as dioxins and holds wastewater comprising a contaminated matter such as fly ash which comprises dioxins and which is produced by washing of a facility such as an incinerator. Air is supplied by a blower (6) to a matter held in the reaction tank (5). Accordingly, dioxins having three or more chlorine atoms in the contaminated matter can be decomposed, and the contaminated matter can be easily cleaned at a site where dioxins generate such as a washing or dismantling site of an incineration facility.Type: GrantFiled: March 19, 2004Date of Patent: October 6, 2009Assignees: Takasago Thermal Engineering Co., Ltd., Engineering Advancement Association of JapanInventors: Sadayori Hoshina, Atsushi Takahashi, Noboru Iiyama, Hitoshi Inaba

Publication number: 20090233360Abstract: The present invention provides methods and compositions for the propagation and expansion of neural precursor cells (NPCs). NPCs may be used in the clinical implementation of stem cell therapy to treat disorders such as Parkinson's disease, Huntington's disease, neuropathic pain and other diseases of the central nervous system. The large-scale production of NPCs in bioreactors allows for the generation of clinical quantities of these cells.Type: ApplicationFiled: March 17, 2009Publication date: September 17, 2009Inventors: Behnam A.

Patent number: 7579179Abstract: A product exhibiting an improved cell growth surface and cell attachment. According to the present invention, a stream of plasma is comprised of activated gaseous species generated by a microwave source. This stream is directed at the surface of a polymer substrate in a controlled fashion such that the surface is imparted with attributes for cell adhesion far superior to that of untreated polymer or polymer treated by other methods.Type: GrantFiled: March 5, 2003Date of Patent: August 25, 2009Assignee: Corning IncorporatedInventors: Marie D. Bryhan, Paul E. Gagnon, Oliva V. Lachance, Zhong-he Shen, Hongming Wang
