The sequences of the 3'-terminal 1306 and 2160 nucleotides of RNAs 1 and 2 of a virus serologically related to Satsuma dwarf virus (SDV) from Hyuganatsu ( Citrus tamurana Hort. ex Tan.) were determined, respectively. We found that the partial RNA-dependent RNA polymerase region in RNA1 and the coat proteins (CPs) region in RNA2 of the virus tentatively named Hyuganatsu virus (HV) have 78.3-84.0% and 76.9-80.7% amino acid sequence identities to those of known SDV-related viruses (SDV-RVs), i.e., SDV, Citrus mosaic virus, and Navel orange infectious mottling virus. Sequence analyses show that HV is classifiable as a new SDV-RV species.
ObjectivesThe accumulation of advanced glycation end products (AGEs) may be involved in the pathophysiology of several neuropsychiatric diseases. In this study, the skin AGEs level of several neuropsychiatric diseases was assessed with a simple noninvasive method. Moreover, whether skin AGE level can be used as a biomarker for the diagnosis of these diseases was evaluated.MethodsA total of 27 patients with schizophrenia, 26 with major depressive disorder, and 10 with major neurocognitive disorders (MNDs), such as Alzheimer's disease or dementia with Lewy body, as well as 26 healthy controls were enrolled in this study. The skin AGE levels of the patients were assessed with an AGE scanner, a fluorometric method used to assay skin AGE levels.ResultsOne‐way analysis of covariance was performed after adjusting for significant covariates, including age. Although the group with MNDs had higher skin AGE levels than the other groups, the main effect of diagnosis did not significantly affect the skin AGE levels of the groups.ConclusionsSkin AGE levels in neuropsychiatric diseases with mild symptoms did not significantly differ. Further large‐scale studies using a simple noninvasive method for the early detection and treatment of MNDs must be conducted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
