Abstract: A three-dimensional air bag includes a first three-dimensional sewn portion in which the main panel and the first side panel portion are sewn together, and a second three-dimensional sewn portion in which the main panel and the second side panel portion are sewn together. A part of the first three-dimensional sewn portion and a part of the second three-dimensional sewn portion are located at an upper surface of the deployed and inflated air bag. A shape of the first three-dimensional sewn portion of the main panel in a natural state is different from a shape of the first three-dimensional sewn portion of the first side panel portion in a natural state. A shape of the second three-dimensional sewn portion of the main panel in the natural state is different from a shape of the second three-dimensional sewn portion of the second side panel portion in a natural state.

Abstract: A bag holder includes an insertion hole allowing a main body of an inflator to be inserted. A retainer includes a pressing portion that presses a peripheral edge of an inflow opening of an airbag, and an internal thread is provided on an inner peripheral surface side of the pressing portion. The inflator includes an external thread screwable to the internal thread on an outer peripheral surface side, in the main body. The retainer causes, at the time of screwing the internal thread and the external thread to each other, the pressing portion and the flange portion to sandwich a portion of a peripheral edge of the insertion hole in the bag holder, thereby causing the bag holder to hold the airbag and the inflator. The retainer includes a projection extending from the pressing portion and capable of penetrating through the airbag and the bag holder.

Abstract: Novel factors which are involved in the mechanism of the onset of IgA nephropathy are explored, and diagnostic, preventive or therapeutic agents for this disease are provided. A method for measuring autoantibodies related to IgA nephropathy, the method comprising measuring the amount of anti-spectrin ? IgA antibodies in a sample derived from a living organism.

Abstract: It is an object of the present invention to provide a method for efficiently producing a B cell population comprising B cells that recognize a specific antigen. According to the present invention, provided is a method for producing a B cell population, comprising: a step (c) of culturing a cell population comprising B cells together with a specific antigen in the absence of IL-21, in the absence of IL-4, and in the presence of a cytokine other than IL-21 and IL-4, while giving stimulation mediated by CD40 and a BAFF receptor to the cells; and a step (d) of culturing the cell population comprising B cells, while giving stimulation mediated by has to the cells, so as to obtain a B cell population comprising B cells that recognize the specific antigen.

Abstract: In an internal combustion engine in which a plurality of cylinders are arranged in series in a cylinder section, pressures of the cylinders can be detected by a smaller number of pressure sensors. An engine in which a plurality of cylinders are arranged in series in a cylinder section includes a communication path through which combustion chambers of the cylinders adjacent to each other communicate with each other, and a pressure sensor is disposed in the communication path.

Abstract: It is an object of the present invention to provide a method for easily producing an antigen-specific B cell population comprising IgG-positive B cells specific to a specific antigen. The present invention provides a method for producing a B cell population, comprising culturing B cells, in which the expression of a Bach2 gene has been increased, in the presence of a means for acting on CD40 and/or a BAFF receptor.

Abstract: An airbag includes a mounting region, a protection inflatable region and an intermediate region disposed between the mounting region and the protection inflatable region. An area of the airbag from the protection inflatable region to the intermediate region is formed of two panels that are continuous with each other at leading end regions of the panels apart from the mounting region and the two panels in that area are connected at opposite edges by a joint. The protection inflatable region includes at the leading end a folded region that is formed by bringing the leading end regions of the two panels closer to the mounting region so as to form four or more layers of the panels, such that the folded region includes at least two inflatable spaces between the layers and a crease that is continuous with the joint.
