Erythrocyte ‘Feierzeit’ reaction: Novel filamentous and vesicular response to n‐butyl acetate

Journal of Microscopy, EarlyView.
Abstract Human erythrocytes (red blood cells; RBCs) undergo spontaneous disassembly after several hours of exposure to n‐butyl acetate (nBA). Images of the morphological changes were captured in time‐lapse sequences using differential interference contrast (DIC) light microscopy.

The Effect of Different Mandibular Advancement Devices on Sleep Parameters in Obstructive Sleep Apnea

Journal of Oral Rehabilitation, EarlyView.
Obstructive sleep apnea arises from repeated upper airway collapse during sleep, causing apnea events. Mandibular advancement devices (MADs) treat this by advancing the mandible to open the airway. Three device types—conventionally manufactured (Mundgleiter) and CAD/CAM‐manufactured (OPTISLEEP, Narval CC)—were compared, with an average mandibular ...
