Publication number: 20110186731Abstract: The present invention relates to an improved LCMS technology and its uses in methods for the selective identification and characterization of immunogenic pathogen associated epitopes, and the use thereof in vaccine development. One way of bridging the knowledge gap on T cell epitopes is to apply a new platform technology, “immunoproteomics”, to directly assess the epitope display at the surface of antigen presenting cells by nanoscale mass spectrometry of extracted peptide samples. This is the only methodology that can provide unbiased insight into epitope features such as the exact molecular nature, diversity, abundance, dynamics and PTM of T cell epitopes originating from pathogen-derived proteins. Therefore, this platform technology and immunoproteomics should become an intrinsic part of vaccinology.Type: ApplicationFiled: September 9, 2009Publication date: August 4, 2011Applicant: DE STAAT DER NEDERLANDEN, VERT.

Publication number: 20100313580Abstract: An atomizing electrode includes: a trunk unit made to be tabular-shaped and almost rectangular-shaped for receiving water dropped from water supply means in a direction of gravitational force and delivering the water; and a top end atomizing unit which is a plate-shaped projection formed so as to be projected from a side surface of the trunk unit and formed unitedly with the trunk unit. The trunk unit of the atomizing electrode extends a long-side direction in a horizontal direction, is provided below the cooling unit with a space of a predetermined distance so as not to contact the cooling unit, and is arranged so that when the cooling unit is projected in the direction of gravitational force, a width of the cooling unit in a horizontal direction should be included in a width of a long-side direction of a top surface of the trunk unit exposed to the cooling unit.Type: ApplicationFiled: May 18, 2010Publication date: December 16, 2010Applicant: Mitsubishi Electric CorporationInventors: Reiji MORIOKA, Takahiro Sakai

Patent number: 7841549Abstract: An electrostatic spraying device has a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed. The device includes a nozzle for dispensing the liquid and an emitter electrode disposed adjacent to the nozzle for charging the liquid composition just being dispensed from the nozzle. A field electrode surrounds the reservoir in order to charge the liquid composition within the reservoir, thereby avoiding an occurrence of electric current which would deteriorate the composition remaining in the reservoir. The reservoir is at least partially made of deformable material such that the reservoir is capable of receiving pressure to deform and thus supply the liquid composition out of the reservoir. Thus, the reservoir can be designed into a simple and compact structure, thereby providing an increased liquid containing volume in relation to the bulk of the removable cartridge.Type: GrantFiled: February 9, 2004Date of Patent: November 30, 2010Assignees: Panasonic Electric Works Co., Ltd., The Procter & Gamble CompanyInventors: Naoki Yamaguchi, Shunichi Nagasawa, David Edward Wilson

Patent number: 7837134Abstract: An emitter electrode is cooled by a cooler to generate condensed water which is charged by a high voltage applied between the emitter electrode and an opposed electrode and is discharged as a mist of charged minute water particles. A controller is provided to vary a temperature drop to a predetermined minimum temperature in dependence of an environmental temperature detected by a temperature sensor. The temperature drop is made variable in proportion to the environmental temperature. Accordingly, a sufficient amount of water can be condensed on the emitter electrode simply by controlling the cooling of the emitter electrode without relying upon an environmental humidity.Type: GrantFiled: December 18, 2006Date of Patent: November 23, 2010Assignee: Panasonic Electric Works Co., Ltd.Inventors: Shousuke Akisada, Sumio Wada, Toshihisa Hirai, Kishiko Hirai, legal representative, Mikio Itou, Kyohei Kada

Patent number: 7823809Abstract: An electrostatic spraying device has a capability of confirming that the device is ready for making an electrostatic spraying of the liquid composition on a user's skin. The device includes a nozzle and a pump for dispensing the liquid composition out through the nozzle. An emitter electrode is disposed to electrostatically charge the liquid composition being dispensed for making the electrostatic spraying. The device is provided with a power switch and a selector for selection between a spraying mode and a dripping mode. In the dripping mode, the pump is alone actuated to dispense the liquid composition absent electrostatic charge. In the spraying mode, both of the pump and the emitter electrode are activated to make the electrostatic spraying. Thus, the user can be easy to drip the liquid composition by simply manipulating the selector prior to initiating the electrostatic spraying.Type: GrantFiled: November 26, 2004Date of Patent: November 2, 2010Assignees: Panasonic Electric Works Co., Ltd., The Procter & Gamble CompanyInventors: Naoki Yamaguchi, Koji Asakawa, David Edward Wilson, Kazumi Toyama, Meei-Lih Lin

Patent number: 7823808Abstract: An electrostatic spraying device having a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed on a user's skin. The device includes a nozzle for dispensing the liquid as well as an emitter electrode disposed adjacent to the nozzle for charging the liquid composition just being dispensed from the nozzle. A field electrode surrounds the reservoir in order to charge the liquid composition within the reservoir, thereby avoiding an occurrence of electric current which would otherwise flow in the liquid composition and would deteriorate the composition remaining in the reservoir. The reservoir is devoid of the field electrode, and therefor can be designed into a simple and compact structure without being restricted by the field electrode, assuring to have an enhanced liquid containing volume in relation to the bulk of the removable cartridge.Type: GrantFiled: February 9, 2004Date of Patent: November 2, 2010Assignees: Panasonic Electric Works Co., Ltd., The Procter & Gamble CompanyInventors: Naoki Yamaguchi, Koji Asakawa, David Edward Wilson, Shunichi Nagasawa
