The poly(ADP-ribose) polymerases (PARPs) participate in many biological and pathological processes. Here we report that the PARP-13 shorter isoform (ZAPS), rather than the full-length protein (ZAP), was selectively induced by 5'-triphosphate-modified RNA (3pRNA) and functioned as a potent stimulator of interferon responses in human cells mediated by the RNA(More)
A total of 232 isolates of gram-negative bacteria were recovered from mammals, reptiles, and birds housed at Asa Zoological Park, Hiroshima prefecture, Japan. Forty-nine isolates (21.1%) showed multidrug resistance phenotypes and harbored at least one antimicrobial resistance gene. PCR and DNA sequencing identified class 1 and class 2 integrons and many(More)
Most atypical antipsychotic drugs increase acetylcholine release in the prefrontal cortex, but the detailed mechanism is still unknown. The present study examined the role of serotonin (5-HT)1A receptors in risperidone-induced increases in acetylcholine release in rat prefrontal cortex. Systemic administration of risperidone at doses of 1 and 2 mg/kg(More)
Alzheimer's disease (AD) is the most common cause of dementia. Humanin (HN) is a short bioactive peptide abolishing neuronal cell death induced by various familial AD (FAD)-causative genes and amyloid-beta (Abeta) in vitro. It has been shown that HN suppresses memory impairment of mice induced by intracerebroventricular administration of Abeta. To(More)
Sixty Gram-negative bacterial isolates were collected from Palestinian hospitals in 2006. Thirty-two (53.3%) isolates showed multidrug resistance phenotypes. PCR and DNA sequencing were used to characterize integrons and antimicrobial resistance genes. PCR screening showed that 19 (31.7%) and five (8.3%) isolates were positive for class 1 and class 2(More)
Imported animals, especially those from developing countries, may constitute a potential hazard to native animals and to public health. In this study, a new flock of lesser flamingos imported from Tanzania to Hiroshima Zoological Park were screened for multidrug-resistant Gram-negative bacteria, integrons and antimicrobial resistance genes. Thirty-seven(More)
Protein O-linked fucosylation is an unusual glycosylation associated with many important biological functions such as Notch signaling. Two fucosylation pathways synthesizing O-fucosylglycans have been reported on cystein-knotted proteins, that is, on epidermal growth factor-like (EGF-like) domains and on thrombospondin Type 1 repeat (TSR) domains. We report(More)
In the early development of the central nervous system, neural progenitor cells divide in an asymmetric manner and migrate along the radial glia cells. The radial migration is an important process for the proper lamination of the cerebral cortex. Recently, a new mode of the radial migration was found at the intermediate zone where the neural progenitor(More)
