RNA imaging technology is essential for understanding the complex RNA regulatory mechanisms and serves as a powerful tool for disease diagnosis. However, conventional RNA imaging methods often require multiple fluorescent tags for the specific labeling of individual targets, complicating both the imaging process and subsequent analysis. Herein, we develop an RNA sensor that integrates a blocked CRISPR RNA (crRNA)-based conformational switch with a controllable CRISPR activation (CRISPRa) system and apply for RNA imaging.

Fungal trunk diseases are of major concern for tree fruit, nut, and grape growers throughout the world. These diseases include Eutypa dieback of grape, caused by , band canker of almond, caused by and , and twig and branch dieback of walnut, caused by , Botryosphaeria dieback of grape, caused by , and , and esca of grape, caused by and . Given the common occurrence of mixed infections, and the similar wood symptoms at the macroscopic level, species-specific detection tools are needed.

Diagnosing cardiac amyloidosis (CA) is challenging because of its phenotypic heterogeneity, multiorgan involvement requiring interaction among experts in different specialties and subspecialties, lack of a single noninvasive diagnostic tool, and still limited awareness in the medical community. Missing or delaying the diagnosis of CA may profoundly impact on patients' outcomes, as potentially life-saving treatments may be omitted or delayed. The suspicion of CA should arise when "red flags" for this condition are present, together with increased left ventricular wall thickness.

Division of Cardiology, Department of Pharmacy, Health and Nutritional Sciences, University of Calabria, Rende (CS).
Brugada syndrome (BrS) is a genetic condition that increases the risk of life-threatening arrhythmias, which can result in sudden cardiac death (SCD). Implantable loop recorders (ILRs) have become a key tool in managing patients with unexplained syncope, and guidelines advise their use in individuals with recurrent, unexplained syncope or palpitations. However, the role of ILRs in inherited arrhythmic conditions like BrS remains a topic of debate.

Department of Kinesiology and Sport Sciences, University of Miami, Coral Gables, FL, United States of America.
The KinaTrax markerless motion capture system, used extensively in the analysis of baseball pitching and hitting, is currently being adapted for use in clinical biomechanics. In clinical and laboratory environments, repeatability is inherent to the quality of any diagnostic tool. The KinaTrax system was assessed on within- and between-session reliability for gait kinematic and spatiotemporal parameters in healthy adults.
