Abstract: A resolver integrated-type bearing device includes a bearing configured to rotatably support a rotating shaft with respect to a housing, a rotor attached to the rotating shaft, and a stator disposed radially outward of the rotor with a gap therebetween. A stator core of the stator is integrally attached to the bearing.

Abstract: A bar portion is formed so that an outer circumferential surface on a tip portion side is located on an inner diameter side with respect to an outer circumferential surface of a main portion. On an inner diameter side of a cage, lightened portions obtained by notching in an axial direction from an axial side surface of the main portion are formed separately at positions of the respective bar portions in a circumferential direction. Each lighting portion is formed separately from a surface of a pocket and an axially outer surface of the bar portion formed between a pair of claw portions. An axial dimension T1 of a wall portion formed between an axially outer surface of the bar portion and an inner wall surface of the lightened portion is greater than an axial dimension T2 of the main portion on a bottom portion of the pocket.

Abstract: According to embodiments, a method of producing insulin-producing tissues (IPTs) by culturing comprises: preparing non-endocrinal epithelial cells (NEECs) and vascular endothelial cells (VECs), which have been isolated or originated from postnatal pancreata, preferably by capturing of NEECs by collagen; culturing in vitro the NEECs and the VECs at least partly separately from each other; and then generating in vitro a tissue complex (IPTs) that contains both the NEECs and the VECs. In another embodiment, the native islet cells are seeded on a monolayer of VECs that have preferably been separately cultured and purified. In a further embodiment, a method of enriching NEECs comprises: culturing NEECs adhering to a container or substrate; removing NEECs by treating with a tissue-dissociation enzyme to leave left-over cells (LOCs) still attached on the container or substrate; and culturing NEECs in a medium conditioned by, or in the presence of the LOCs.

Abstract: A cryopreservation medium and a cryopreservation method which make it possible to cryopreserve tissues and cells with high viability are provided. A cryopreservation medium contains polyphenol at a concentration of from 30 to 120 ppm. In an embodiment, a cryopreservation method for tissues and cells comprises: incubating tissues or cells for 2 hours in culture medium supplemented with polyphenol at concentrations of from 30 to 120 ppm; suspending tissues or cells in a cryopreservation medium; freezing the suspension of the tissues or cells in the cryopreservation medium; and storing the frozen suspension of tissues or cells in the cryopreservation medium.

Abstract: The invention is directed to an anergy-inducing cellular composition comprising: cells having antigenic determinants on the cell surface and an anergy-inducing compound [e.g., (?)-epigallocatechin-3-o-gallate (EGCG)] attached by its chemical affinity to the antigenic determinants. In one embodiment, the anergy-inducing compound blocks co-stimulatory molecules among the antigenic determinants of the cells, which upon encountering with T-cell renders the latter anergic, that is, unresponsive toward alloantigens. In another embodiment, EGCG is of high purity for its efficient attachment to the antigenic determinants. The anergy-inducing cellular composition is prepared by immersing the cells in a culture media solution (RPMI 1640) containing 50-500 ppm EGCG at low physiological temperatures for one to two hours to minimize the cells' mortality.
