The collectins family encompasses several collagenous Ca-dependent defense lectins that are described as pathogen recognition molecules. They play an important role in both adaptive and innate immunity. Surfactant proteins A and D are two of these proteins which were initially discovered in association with surfactant in the pulmonary system. The structure, immune and inflammatory functions, and genetic variations have been well described in relation to their roles, function and pathophysiology in the pulmonary system. Subsequently, these proteins have been discovered in a wide range of other organs and organ systems. The role of these proteins outside the pulmonary system is currently an active area of research. This review intends to provide a current overview of the genetics, structure and extra-pulmonary functions of the surfactant collectin proteins.

Best Practices for Imaging of Transcatheter Valve Failure: An Update From the Heart Valve Collaboratory.
J Am Coll Cardiol
March 2025
Cedars Sinai Medical Center, Los Angeles, California, USA. Electronic address:
This updated Heart Valve Collaboratory framework addresses the growing concern for transcatheter valve failure (TVF) following transcatheter aortic valve replacement (TAVR). With the increasing volume of redo-TAV and surgical TAV explantation, there is a critical need for standardized pathways and protocols for evaluating TVF using echocardiography and cardiac computed tomography (CT) angiography. This document clarifies prior definitions of bioprosthetic valve deterioration and bioprosthetic valve failure in a practical, imaging directed context for TAVR.

Department of Prevention and Treatment, Hunan Institute for Tuberculosis Control (Hunan Chest Hospital), Changsha 410013, China.
Objectives: Reducing mortality during anti-tuberculosis treatment is crucial for completing full-course standardized therapy and achieving tuberculosis cure. The study aims to analyze the mortality and its influencing factors among pulmonary tuberculosis patients undergoing anti-tuberculosis treatment in Hunan Province.
Methods: In this retrospective cohort study, data on pulmonary tuberculosis patients from the Hunan Provincial Tuberculosis Management Information System were collected between January 1, 2019 and December 31, 2023.
In vitro study of a siRNA delivery liposome constructed with an ionizable cationic lipid.

Department of Pharmaceutical Engineering, Chemistry and Chemical Engineering, Central South University, Changsha 410083.
Objectives: Small interfering RNA (siRNA) can silence disease-related genes through sequence-specific RNA interference (RNAi). Cationic lipid-based liposomes effectively deliver nucleic acids into the cytoplasm but often exhibit significant toxicity. This study aims to synthesize a novel ionizable lipid, Nε-laruoyl-lysine amide (LKA), from natural amino acids, constructed LKA-based liposomes, and perform physicochemical characterization and cell-based experiments to systematically evaluate the potential of these ionizable lipid-based liposomes for nucleic acid delivery.

While biomarker-guided treatments and NGS-based approaches are refining precision medicine, they are not universally applicable. The gap between the genomic characterization of tumors and their functional behavior is becoming increasingly evident. There is an escalating demand for functional assays that can customize cancer treatments for individual patients and bridge this gap.
