Tactical Behaviors in Men's and Women's Middle-Distance Global Championship Track Finals.
Int J Sports Physiol Perform
January 2025
Sports Science Research Center, Rey Juan Carlos University, Madrid, Spain.
Purpose: To analyze tactical behaviors associated with performance in track middle-distance global championship finals.
Methods: Finalists' season-best finishing race time, 100-m section times, and intermediate positions were obtained from 800- and 1500-m men's and women's finals in 2 Olympic Games and 5 World Championships. Differences between medalists, fourth- to eighth-ranked (T8), and ninth- to 12th/13th-ranked finalists in relative performance (relative to season-best), race time, and section times were determined.
The actin filament pointed-end depolymerase Srv2/CAP depolymerizes barbed ends, displaces capping protein, and promotes formin processivity.

Cellular actin networks exhibit distinct assembly and disassembly dynamics, primarily driven by multicomponent reactions occurring at the two ends of actin filaments. While barbed ends are recognized as the hotspot for polymerization, depolymerization is predominantly associated with pointed ends. Consequently, mechanisms promoting barbed-end depolymerization have received relatively little attention.

Gene therapy has long been a cornerstone in the treatment of rare diseases and genetic disorders, offering targeted solutions to conditions once considered untreatable. As the field advances, its transformative potential is now expanding into oncology, where personalized therapies address the genetic and immune-related complexities of cancer. This review highlights innovative therapeutic strategies, including gene replacement, gene silencing, oncolytic virotherapy, CAR-T cell therapy, and CRISPR-Cas9 gene editing, with a focus on their application in both hematologic malignancies and solid tumors.

As one of the essential components of reactive oxygen species (ROS), peroxynitrite (ONOO-) plays an indispensable role in redox homeostasis and signal transduction processes, and its deviant levels are associated with numerous clinical diseases. Therefore, accurate and rapid detection of intracellular ONOO- levels is crucial for revealing its role in physiological and pathological processes. Herein, we constructed a ratiometric fluorescent probe to detect ONOO- levels in biological systems.

Microelectrodes offer exceptional sensitivity, rapid response, and versatility, making them ideal for real-time detection and monitoring applications. Photoelectrochemical (PEC) sensors have shown great value in many fields due to their high sensitivity, fast response, and ease of operation. Nevertheless, conventional PEC sensing relies on cumbersome external light sources and bulky electrodes, hindering its miniaturization and implantation, thereby limiting its application in real-time disease monitoring.
