A method was developed to study simultaneously 1) release of ACh from nerve varicosities and terminals in and 2) motility of the myenteric plexus-free circular muscle of the canine ileum. Tissues were incubated with 3H-choline. Release of 3H was analyzed before and during electrical field stimulation of nerves in the presence and absence of choline oxidase. The major components released into th...

Abstract Peptides with strong binding affinities for poly(methyl methacrylate) (PMMA) resin were designed by use of materials informatics technology based on molecular dynamics simulation the purpose covering surface adhesive peptides, which expected to result in eco-friendly and biocompatible biomaterials. From results affinity obtained this simulation, it was confirmed that experimental value...

Aim: Acetylsalicylic acid (ASA, aspirin), which is one of the most frequently used drugs in the world, causes severe gastric mucosal injury. Nitric oxide (NO) is synthesized from L-arginine by nitric oxide synthase (NOS). NOS can be inhibited by Nω-nitro-L-arginine methyl ester (L-NAME) and stimulated by supplementing the diet with L-arginine (L-Arg). The aim of this study was to investigate th...

Protein arginine methyltransferase 5 (PRMT5) is a protein arginine methyl transferase that catalyzes the symmetrical dimethylation of arginine residues within target proteins. PRMT5 is shown to associate with and methylate histone or non-histone proteins in cells, and plays key roles in cell development, survival and apoptosis. In this review, the current state of knowledge and functional roles...

Glutamate release after ischemia, hypoxia and seizure activity plays an important role in stimulating adenosine production and release. We characterized the ionotropic glutamate receptor subtype that regulates adenosine levels in vivo and investigated the role of nitric oxide and free radicals in mediating N-methyl-D-aspartate (NMDA)-induced increases in adenosine levels. Rats received unilater...

SMN (Survival motor neuron protein) was characterized as a dimethyl-arginine binding protein over ten years ago. TDRD3 (Tudor domain-containing protein 3) and SPF30 (Splicing factor 30 kDa) were found to bind to various methyl-arginine proteins including Sm proteins as well later on. Recently, TDRD3 was shown to be a transcriptional coactivator, and its transcriptional activity is dependent on ...

The germination of Bacillus cereus T spore suspensions is partially prevented by several inhibitors of trypsin-like enzymes. Leupeptin, antipain, and tosyl-lysine-chloromethyl ketone are effective inhibitors, whereas chymostatin, elastatinal, and pepstatin are inactive. A synthetic substrate of trypsin, tosyl-arginine-methyl ester, also inhibits germination. Its inhibitory effect decreases as a...
