Abstract: A novel memory device is provided. The memory device includes a plurality of first wirings extending in a first direction, a plurality of memory element groups, and an oxide layer extending along a side surface of the first wiring. Each of the memory element groups includes a plurality of memory elements. Each of the memory elements includes a first transistor and a capacitor. A gate electrode of the first transistor is electrically connected to the first wiring. The oxide layer includes a region in contact with a semiconductor layer of the first transistor. A second transistor is provided between the adjacent memory element groups. A high power supply potential is supplied to one or both of a source electrode and a drain electrode of the second transistor.

Abstract: A method of diagnosing cerebral infarction comprising the step of measuring the concentration of nick ?2 glycoprotein I in a body fluid sample; and a method of diagnosing cerebral infarction comprising the steps of measuring the nicked ?2 glycoprotein I concentration (N) and the total ?2 glycoprotein I concentration (T) in a body fluid sample, calculating the ratio (N/T) of the nicked ?2 glycoprotein I concentration (N) to the total ?2 glycoprotein I concentration (T), and using the ratio as an indicator, are disclosed.

Abstract: A monoclonal antibody having inhibitory activity on blood coagulation reactions, which reacts with prothrombin forming a complex with phosphatidylserine but does not react with prothrombin not forming a complex with phosphatidylserine; and a method for measuring inhibitory activity of test plasma on blood coagulation reactions, which comprises the steps of (1) measuring inhibitory activity of the test plasma on the blood coagulation reactions and inhibitory activity of this on the blood coagulation reactions, and (2) comparing the inhibitory activity of the test plasma with the inhibitory activity of this antibody.
