Abstract: For example, an I/O circuit is formed by freely combining a plurality of kinds of standard cells included in a cell library. The plurality of kinds of standard cells include at least first standard cells and a second standard cell. The first standard cells include first protection elements and a first power line formed in a region over the first protection elements to conduct to the first protection elements. The second standard cell includes a second protection element formed in a layout identical with that of the first protection elements, and a second power line formed in a region over the second protection element to conduct to the second protection element while being isolated from the first power line.

Abstract: An imine compound represented by the formula: wherein A represents a heterocyclic group; R1, R2, an R3 each represent a hydrogen atom, a halogen atom, a C1-10 alkyl group optionally substituted with an aryl group(s) substituted with a halogen atom(s), a C3-10 cycloalkyl group, a C1-6 haloalkyl group, a C1-10 alkoxy group, etc.; R4 represents an optionally substituted C1-10 alkyl, C2-6 alkenyl, or aryl group; R5 represents a hydrogen atom, a C1-10 alkoxy group, a C1-6 haloalkyl group, an optionally substituted C1-10 alkyl or C2-6 alkenyl group, an optionally substituted aryl or heterocyclic group, etc.; W represents —CO—, —CO—CO—, —CO—NH—, —CS—NH—, or —SO2—, or a cannabinoid-receptor agonist comprising said imine compound as an active ingredient. The imine compound of the present invention has a cannabinoid-receptor agonist effect, and is useful as a therapeutic or prophylactic drug for pains and autoimmune diseases.

Abstract: Compounds, compositions and methods that are useful in the treatment of immunoregulatory conditions and disorders are provided herein. In particular, the invention provides compounds which modulate the function of a Signal Transducer and Activator of Transcription (STAT) protein. The compounds are represented by the general formula: wherein Y, Ar, X, A2, A1, R1 and R2 are defined herein. The compounds are useful to treat, for example, allergic and inflammatory conditions and disorders.

Abstract: A novel parenchymal hepatocyte growth factor originating in a human or animal liver, having an estimated molecular weight according to nonreductive SDS-PAGE of about 63,000 to about 69,000, an estimated molecular weight according to reductive SDS-PAGE of about 32,000 to about 36,000 and an estimated molecular weight according to gel filtration of about 60 to about 70 Kd; and having an activity of effecting the growth of parenchymal hepatocyte has been obtained from the hemihepatectomized tissue. Furthermore, a gene coding for the above substance has been obtained from the mRNA of the above tissue and it has thus become possible to mass-produce the above substance.

Abstract: An enhancer DNA segment having an excellent action of enhancing the transcriptional efficiency of an incorporated gene in a cell, said segment being derived from a human papovavirus BK mutant designated as pm411, pm522 or pm525.The enhancer DNA segment is useful for enhancing the expression of a gene encoding a biologically active substance in host eukaryotic cells.

Abstract: An amplitude modulation circuit which comprises a modulating circuit for applying a modulating signal to a modulated stage, and a voltage regulator arranged to regulate a D.C. voltage to be supplied to the modulated stage at a predetermined constant level and having a circuit means adapted to provide a high impedance for the modulating signal applied to the modulated stage.
