Molecular composites, such as bone and nacre, are everywhere in nature and play crucial roles, ranging from self-defense to carbon sequestration. Extensive research has been conducted on constructing inorganic layered materials at an atomic level inspired by natural composites. These layered materials exfoliated to 2D crystals are an emerging family of nanomaterials with extraordinary properties.

Chirality, a pervasive phenomenon in nature, is widely studied across diverse fields including the origins of life, chemical catalysis, drug discovery, and physical optoelectronics. The investigations of natural chiral materials have been constrained by their intrinsically weak chiral effects. Recently, significant progress has been made in the fabrication and assembly of low-dimensional micro and nanoscale chiral materials and their architectures, leading to the discovery of novel optoelectronic phenomena such as circularly polarized light emission, spin and charge flip, advocating great potential for applications in quantum information, quantum computing, and biosensing.

AT2 dysfunction underlies many lung diseases, including interstitial lung disease (ILD), in which some inherited forms result from the mislocalization of surfactant protein C (SFTPC) variants. Lung disease modeling and dissection of the underlying mechanisms remain challenging due to complexities in deriving and maintaining human AT2 cells ex vivo.

Objectives: There are currently major inconsistencies in the methodological approaches used to index social frailty. The present study aimed to better understand which of these approaches may be most valuable in predicting older adult's physical health and psychological wellbeing.
Design: One hundred and thirty-three participants aged 60-90 years completed five measures commonly used to index social frailty, along with five measures of physical health, and psychological wellbeing.
Clinical Characteristics and Outcomes of Patients Undergoing 3 Aortic Valve Interventions: The THIRD Multicenter Registry.

January 2025
Department of Cardiac, Thoracic, Vascular Sciences and Public Health, University of Padua, Padua, Italy.
Background: Lifetime treatment of aortic valve disease is a matter of increasing debate. Although the risks of a second aortic valve intervention are recognized, little attention has been given to the challenges of a third.
Objectives: This study delves into the clinical characteristics, indications, and outcomes of patients undergoing 3 aortic valve interventions.
