Selective production of olefins from methanol over a heteroatomic SAPO-34 zeolite.

The methanol-to-olefins (MTO) process has the potential to bridge future gaps in the supply of sustainable lower olefins. Promoting the selectivity of propylene and ethylene and revealing the catalytic role of active sites are challenging goals in MTO reactions. Here, we report a novel heteroatomic silicoaluminophosphate (SAPO) zeolite, SAPO-34-Ta, which incorporates active tantalum(V) sites within the framework to afford an optimal distribution of acidity.

Teaching high quality paediatric basic life support to laypeople: The development and evaluation of a virtual simulation game.

Background: Self-directed training has been recognized as a reasonable alternative to traditional instructor-led formats to teach laypeople Basic Life Support (BLS). Virtual tools can facilitate high-quality self-directed resuscitation education; however, their role in teaching paediatric BLS remains unclear due to limited empiric evaluation and suboptimal design of existing tools.

Aim: We describe the development and evaluation of a virtual simulation game (VSG) designed to teach high-quality paediatric BLS using a self-directed, online format with integrated deliberate practice and feedback.

Use of Maternal-Fetal Medicine Subspecialist Services by Commercially Insured Pregnant People.

Importance: Improving access to high-quality maternity care and reducing maternal morbidity and mortality are major policy priorities in the US. Previous research has primarily focused on access to general obstetric care rather than access to high-risk pregnancy care provided by maternal-fetal medicine subspecialists (MFMs).

Objective: To measure access to MFM services and determine patient factors associated with MFM service use, including MFM telemedicine.

Duplication Syndrome: AI-Based Diagnosis, Severity Scale Development and Correlation with Clinical and Molecular Variables.

: duplication syndrome (MDS) (MIM#300260) is a rare X-linked neurodevelopmental disorder. This study aims to (1) develop a specific clinical severity scale, (2) explore its correlation with clinical and molecular variables, and (3) automate diagnosis using the Face2gene platform. : A retrospective study was conducted on genetically confirmed MDS patients who were evaluated at a pediatric hospital between 2012 and 2024.
