Objectives: We aimed to evaluate the performance of the optic disc-macula distance to disc-diameter ratio (DM/DD) in qualitative and quantitative assessment of optic disc size.

Methods: In 300 apparently normal eyes, we determined the correlation between DM/DD and the planimetric disc area (DA) and evaluated the performance of DM/DD in discriminating between small and large discs. The ability of DM/DD to predict the actual DA was validated in a separate cohort of 200 eyes.

Polymer-in-salt electrolytes were introduced three decades ago as an innovative solution to the challenge of low Li-ion conductivity in solvent-free solid polymer electrolytes. Despite significant progress, the approach still faces considerable challenges, ranging from a fundamental understanding to the development of suitable polymers and salts. A critical issue is maintaining both the stability and high conductivity of molten salts within a polymer matrix, which has constrained their further exploration.

Article Synopsis
  • The study investigates the outcomes of replantation surgery for amputated fingers in elderly patients (aged 65 and above) compared to younger patients, focusing on the feasibility of the procedure as more elderly individuals enter the workforce.* -
  • A cohort of 25 patients (12 elderly and 13 younger) who underwent successful finger replantation was analyzed over a follow-up period of more than one year, assessing key pinch strength, hand dexterity, and overall hand function.* -
  • Results indicated that while elderly patients performed worse on certain dexterity tests, their overall hand function post-surgery was similar to that of younger patients, suggesting that age alone should not deter finger replantation procedures in older adults.*

Background: Japan's stringent licensing policies for older drivers have not been questioned, possibly due to negative perceptions of older drivers potentially influenced by media coverage of their car crashes. We examined whether older drivers' fatal crashes are over-represented in the news articles.

Methods: To examine the news coverage of fatal crashes that occurred between January 2016 and December 2020, we extracted driver- and crash-related data from articles reporting fatal crashes in the two best-selling newspapers, Yomiuri and Asahi.

Human astrovirus (HAstV) is a global cause of gastroenteritis in infants, the elderly, and the immunocompromised. However, the molecular mechanisms that control its susceptibility are not fully understood, as the functional receptor used by the virus has yet to be identified. Here, a genome-wide CRISPR-Cas9 library screen in Caco2 cells revealed that the neonatal Fc receptor (FcRn) can function as a receptor for classical HAstV (Mamastrovirus genotype 1).

Background: Self-disturbance has been considered as a core symptomatology of schizophrenia and its emergence from the prodromal phase makes it a crucial target for early detection and intervention in schizophrenia. Currently, the clinical assessment of self-disturbance relies on the self-report of patients, and clinicians have no diagnostic tools in clinical practice. Identifying the neural substrate of self-disturbance would be of great clinical value by shedding light on the core dimension of schizophrenia.

Article Synopsis
  • Synucleinopathies like Parkinson's disease and dementia involve problems in the brain caused by a protein called α-synuclein.
  • Currently, there are no effective treatments for these disorders, but researchers found that a drug called galantamine might help by preventing harmful protein buildup.
  • Studies showed that galantamine could protect brain cells and stop the spread of α-synuclein in mice, which means it could be a promising new treatment option.

This study evaluated the ability of isolated or semisynthesized trichothecene sesquiterpenes to prevent cancer emergence and proliferation and inhibit signal transducer and activator of transcription-3 (STAT3) phosphorylation through in vitro assays. Trichothecinol A (TTC-A), which bears a hydroxy group at C3, exhibited greater cancer prevention, antiproliferation, and STAT3 phosphorylation inhibition effects than trichothecin (TTC), which lacks a hydroxy group at C3. Furthermore, trichothecinol B (TTC-B), which is a reduced derivative of TTC and has similar cytotoxic effect, showed substantially weaker chemoprotection and STAT3 phosphorylation inhibition effects than TTC.

We previously reported that α-glycosylated naringin (naringin-G), synthesized by enzyme-catalyzed transglycosylation, can enhance the solubility of poorly water-soluble compounds without surface-active property. However, the solubilization mechanism has not been fully elucidated. In this study, the solubilization mechanism of naringin-G was investigated using nuclear magnetic resonance (NMR) spectroscopy, and its application in skin formulations was further investigated.

Article Synopsis
  • The study evaluated the risk factors and drug differences associated with post-endoscopic submucosal dissection (ESD) bleeding in patients using antithrombotic drugs, specifically direct oral anticoagulants (DOACs).
  • Out of 278 patients, those on DOACs experienced a 19.6% incidence of post-ESD bleeding, with risk factors including larger resection size and presence of neutrophil infiltration.
  • The findings suggest that DOACs elevate bleeding risk, particularly noting lower bleeding rates with the drug dabigatran compared to others like apixaban, edoxaban, and rivaroxaban.

Utilities of whey powder (WP) and whey protein concentrate 34% powder (WPC34) prepared as dairy-processing residues were evaluated using a green alga . Analysis of growth showed that the strain used WP and WPC34 as nitrogen sources. Its specific growth rate and maximum cell density in WP-containing medium were higher than those in WPC34-containing medium; growth with WPC34 was improved by adding KCl or KHPO, which content was decreased as a result of WPC34's preparation from WP.

Cerebellar neurons, such as GABAergic Purkinje cells (PCs), interneurons (INs) and glutamatergic granule cells (GCs) are differentiated from neural progenitors expressing proneural genes, including ptf1a, neurog1 and atoh1a/b/c. Studies in mammals previously suggested that these genes determine cerebellar neuron cell fate. However, our studies on ptf1a;neurog1 zebrafish mutants and lineage tracing of ptf1a-expressing progenitors have revealed that the ptf1a/neurog1-expressing progenitors can generate diverse cerebellar neurons, including PCs, INs and a subset of GCs in zebrafish.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system (CNS) caused by reactivation of dormant JC polyomavirus (JCPyV). PML was mainly observed in immunocompromised individuals, such as HIV-positive patients, autoimmune disease patients, and cancer patients. Given that the presence of anti-JCPyV antibodies in serum is a risk indicator for PML development, it is essential to monitor anti-JCPyV antibody levels.
