Title: Process for biochemical optical resulution of cyclopentenolone derivative
Inventor: MITSUDA SATOSHI
IPC: C12P7/26
Filed: 1983-03-18
Granted: 1988-09-15
Abstract: Biochemical optical resolution of (+)-4-hydroxy-3-methyl-2-2'-propynyl- 2-cyclopentenone (propynyl cyclopentenolone) comprises reacting an organic carboxylic acid (1-18C satd. or unsatd. carboxylic acid) ester of propynylcyclopentenolone with an esterase produced by microorganisms or animal pancreatoesterase (e.g. steapsin or pancreatin) to cause symmetrical hydrolysis, resolving into optically active propynyl-cyclopentenolone and ester of its antipode. The asymmetrical hydrolysis is conducted at 10-70 deg.C, and pref. at 50-65 deg.C in case of using a culture of a thermophilic bacterium or heat-resistant esterase obtd. by cultivation of a thermophilic bacterium or at 20-50 deg.C in case of using a culture of a middle temp. bacterium or esterase having no particular heat-resistance for 3-48 hrs. at pH 5-11. The starting ester is used at a concn. of 1-50 wt.%, pref. 5-25 wt.%, based on the reaction mixt.. The steps are simple when compared with conventional organosynthetic chemical optical resolution. Expensive resolving reagents are not necessary. Optically active propynylcyclopentenolone of high purity can be obtd. in high yields.

Title: Suppressing of graft rejection in organ transplantation
Inventor: FABRICIUS HANS-AKE
IPC: C07H15/10
Filed: 1983-05-27
Granted: 1989-05-24
Abstract: Suppression of the immunological rejection mechanism of a host which has received an organ transplant is achieved by the daily administration to the host of a ganglioside agent which effectively blocks the soluble immunological cell mediator interleukin 2 and/or a blastogenic factor. By binding to the mediator for T cell blast formation, the mediator is prevented from binding to the asialo GM1 receptor on the surface of the T effector cell. Blastogenesis does not occur and the cell mediated rejection of the graft is prevented. Examples of suitable gangliosides are desialylated gangliosides such as asialo GM1, GD1a, GD1b or GT1.

Abstract: A slit (7) is formed which lies in a vertical plane and extends from an upper surface of a sewing machine frame (1) to a front surface. A tension device (5), a thread take-up spring (30), and upper and lower thread guides (23, 24) are disposed along the direction in which the slit (7) extends. A thread take-up lever (12) is installed so that it is reciprocated horizontally across the space between the pair of thread guides (23, 25). The placement of the thread in the tension device (5), thread take-up spring (30), and two thread guides (23,24) can be attained by simply pulling the upper thread vertically downward through the slit (7). When the thread take-up lever is reciprocated, during its forward stroke it arrests the portion of the thread positioned between the two thread guides (23, 24) and draws it in V form. During its return stroke, the thread take-up lever (12) releases the thread to allow the latter to loosen in loop form.

Abstract: The grinding disc (1) for shaping the surface of a tool, such as a twist drill (2), so that the zones between the flutes are undercut, uses a disc and a dressing wheel (3) for the disc surface to be undercut to give the required shaping surface. The disc has several undercut zones, and the rotation of the drill and travel of the disc are synchronised so that the undercut of the drill is directly produced by the action of the grinding disc. The dressing wheel is rotated by its spindle, which is also advanced to produce the required shape of the grinding wheel. An electronic control system maintains the correct relationship between movement of the disc, the drill, and the dressing wheel.

The material is pref. polycrystalline or single crystalline, e.g. Si, and is placed during the process on one of the electrodes in a plasma chamber.
