Metabolic activities are selective modulators for individual segmentation clock processes.

Numerous cellular and molecular processes during embryonic development prompt the fundamental question of how their tempos are coordinated and whether a common global modulator exists. While the segmentation clock tempo scales with the kinetics of gene expression and degradation processes of the core clock gene Hes7 across mammals, the coordination of these processes remains unclear. This study examines whether metabolic activities serve as a global modulator for the segmentation clock, finding them to be selective instead.

Clustering patients with COVID-19 according to respiratory support requirements, and its impact on short- and long-term outcome (RECOVID study).

Introduction: The Spanish Society of Pulmonology and Thoracic Surgery created a registry for hospitalised patients with COVID-19 and the different types of respiratory support used (RECOVID). Objectives. To describe the profile of hospitalised patients with COVID-19, comorbidities, respiratory support treatments and setting.

Brand Videos among Orthopedic Surgery Residency Programs.

Objectives: The use of brand videos has provided residency programs with another platform to showcase themselves and attract potential applicants. Despite the rise in brand videos following the COVID-19 pandemic, not all orthopedic surgery residency programs have developed one. This study aimed to determine the prevalence of brand videos on orthopedic surgery residency program websites and evaluate their contents.
