Direct laryngoscopy versus indirect videolaryngoscopy for intubating newborn manikins: a randomised crossover study.

Gaining and maintaining proficiency at endotracheal intubation is challenging. Recent clinical trials suggest videolaryngoscopy is beneficial for teaching inexperienced clinicians to intubate newborn infants, but may take longer compared to standard laryngoscopy. Preferences for devices among clinicians are unclear.

A climate threshold for ocean deoxygenation during the Early Cretaceous.

Oceanic anoxic events (OAEs) are historical intervals of global-scale ocean deoxygenation associated with hyperthermal climate states and biological crises. Massive volcanic carbon dioxide (CO) emissions frequently associated with these events are thought to be a common driver of ocean deoxygenation through several climate-warming-related mechanisms. The Early Cretaceous OAE1a is one of the most intense ocean deoxygenation events, persisting for more than 1 Myr (refs.

Low-pressure continuous dynamic extraction from oak chips combined with passive micro-oxygenation to tune red wine properties.

Static infusion of oak chips in wine is a common practice during wine ageing, aimed at improving sensory properties and stability of wines. The wine/chips contact required to reach the desired effect can last several weeks or months. A low-pressure continuous dynamic (LPCD) extractor in which a closed-circle, low-pressure continuous flow of wine passes through an extraction cell filled with chips, was evaluated as a tool to tune red wine properties in few hours.

Use of vine-shoots stilbene extract to the reduction of SO in red and rosé Italian wine: Effect on phenolic, volatile, and sensory profiles.

Sulfur dioxide (SO) is one of the most used additives in wine industry for its antioxidant and antimicrobial activity. However, due to health concerns, consumers' demand of wines with either reduced or totally replaced SO has increased. This study aimed to assess the effect of partial and total replacement of SO with a vine-shoots extract rich in stilbenes in rosé (cv.

Application of toasted vine-shoot chips and ultrasound treatment in the ageing of Primitivo wine.

Ageing wine in barrels is an historical practice used to improve the aromatic complexity of wine, but due to the high cost and the long ageing period, alternative approaches have been developed, such as the use of wood chips and ultrasound treatment. The present paper reports the results of an investigation performed on wine (cv. Primitivo).
