Algae extract-based nanoemulsions for photoprotection against UVB radiation: an electrical impedance spectroscopy study.

Skin cancer is one of the most common types of cancer worldwide, with exposure to UVB radiation being a significant risk factor for its development. To prevent skin cancer, continuous research efforts have focused on finding suitable photoprotective ingredients from natural sources that are also environmentally friendly. This study aimed to develop oil-in-water photoprotective nanoemulsions containing marine macroalgae extract.

Nanospiked Cellulose Gauze That Attracts Bacteria with Biomolecules for Reducing Bacterial Load in Burn Wounds.

Nanostructuring surfaces is an emergent strategy to endow materials with abilities to combat pathogenic bacteria. Nevertheless, it remains challenging to create nanospike structures on the curved surfaces of polymer materials, including gauze and other microfibrous medical materials. Additionally, the effects of nanostructured surfaces on bacteria in the presence of proteins and in vivo remain largely unexplored.

Traction-assisted endoscopic ultrasound-guided fine-needle biopsy using the clip-with-thread method for small gastric subepithelial lesions: Randomized controlled trial (with video).

Objectives: Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/B) is the gold standard for diagnosing gastric subepithelial lesions (SELs), but diagnosing lesions smaller than 20 mm remains challenging. We developed traction-assisted EUS-FNB (TA-EUS-FNB) using the clip-with-thread method to enhance diagnostic accuracy by stabilizing the lesion and providing counter-traction for easier needle access. This study evaluates the effectiveness of TA-EUS-FNB in diagnosing small gastric SELs.

Association between body size and atrial myopathy: Investigation using the prevalence of left atrial low-voltage areas.

Background: Left atrial low-voltage areas (LVAs) are known to be associated with atrial myopathy and atrial fibrillation (AF) recurrence after catheter ablation. However, the association between body size and prevalence of LVAs has not been fully elucidated. The purpose of this study was to clarify the association between body size and the prevalence of LVAs in patients with AF ablation.

Persistent body-weight change on achalasia and peroral endoscopic myotomy: a multicenter cohort study.

Background: The distribution of body weight in patients with achalasia and after peroral endoscopic myotomy (POEM) has not been investigated. The role of body weight assessment after treatment remains unclear.

Methods: Using the multicenter achalasia cohort, the frequency of underweight (body mass index [BMI] < 18.
