Article Synopsis
- - The study shows that grain boundaries (GBs) act like Brownian ratchets, meaning they can move in a specific direction when subjected to certain oscillating forces or heat cycling, unlike symmetric GBs which do not show this behavior.
- - Researchers used molecular dynamics and phase-field crystal simulations to investigate various types of GBs in both bicrystal and polycrystalline structures, confirming their findings with real-time experiments.
- - A Markov chain model was used to analyze the GB ratchet phenomenon and its potential impact on materials processing and the manipulation of microstructures.
Background: Tracheal intubation is commonly performed after direct laryngoscopy using Macintosh laryngoscopes (MacL), but visualization of the larynx may be inadequate. The VieScope (VSC) as a new type of laryngoscope consisting of a straight, shielded, illuminated tube used to perform intubation a bougie was investigated in this prospective randomized trial in patients without expected difficult airways.
Methods: With ethics approval, 2 × 29 patients for elective surgery were randomized 1:1 to intubation with VSC or MacL.
Tracheal intubation in patients with an expected difficult airway may be facilitated by videolaryngoscopy (VL). The VL viewing axis angle is specified by the blade shape and visualization of the larynx may fail if the angle does not meet anatomy of the patient. A tube with an integrated camera at its tip (VST, VivaSight-SL) may be advantageous due to its adjustable viewing axis by means of angulating an included stylet.

Methods: We retrospectively reviewed patients undergoing HoLEP at our institution between 2012 and 2017. Standard pre-, peri-, and postoperative characteristics were compared according to anesthetic technique.
Background: Children suffering from mucopolysaccharidoses (subtypes I, II, III, IV, VI, and VII) or mucolipidoses often require anesthesia, but are at high risk for perioperative adverse events. However, the impact of the disease subtype and the standard of care for airway management are still unclear.
Aims: This study aimed to assess independent risk factors for perioperative adverse events in individuals with mucopolysaccharidoses/mucolipidoses and to analyze the interaction with the primary airway technique implemented.
