Ischemia and pathological angiogenesis in retinal vascular diseases cause serious vision-related problems. However, the transcriptional regulators of vascular repair remain unidentified. Thus, the factors and mechanisms involved in angiogenesis must be elucidated to develop approaches for restoring normal blood vessels.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus are primarily transmitted through droplets or aerosols from patients. The inactivation effects of existing virus control techniques may vary depending on the environmental factors. Therefore, it is important to establish a suitable evaluation system for assessing virus control techniques against airborne viruses for further real-world implementation.

Background/aims: Visualization of palisade vessels (PVs) in Barrett's esophagus is crucial for proper assessment. This study aimed to determine whether red dichromatic imaging (RDI) improves PV visibility compared with white-light imaging (WLI) and narrow-band imaging (NBI).

Methods: Five expert and trainee endoscopists evaluated the PV visibility in Barrett's esophagus using WLI, NBI, and RDI on 66 images from 22 patients.

Article Synopsis
  • - Sudachitin, a polymethoxyflavone from sudachi peel, shows promise in improving hyperlipidemia but its effects on heart function were investigated, revealing that it enhances heart rate and contractility in rat atria in a dose-dependent manner.
  • - Unlike isoproterenol, which has a stronger impact, sudachitin and other similar compounds like demethoxysudachitin and nobiletin also increase heart function but to a lesser degree; their effects appear non-specific across these compounds.
  • - The study found that sudachitin enhances heart function through cAMP-dependent pathways rather than through β-adrenoceptors, suggesting a unique mechanism for its action among polymethoxyflavones.

A 61-year-old woman who had been taking olmesartan for 7 years complained of epigastric pain, diarrhea, loss of appetite, and weight loss. Esophagogastroduodenoscopy revealed roughened mucosa and erosions in the stomach and duodenum. An endoscopic biopsy failed to identify the cause of the mucosal disorder.
