The well-being of a supervisor is reflected through supervisor-subordinate relationships in employee motivation and performance, and consequently, in the company’s competitiveness. In his doctoral research at the University of Vaasa, Finland, Project Researcher Jussi Tanskanen demonstrates that an exhausted leader lacks the resources to maintain high-quality relationships with subordinates, leading to a collapse in employee dedication. This phenomenon is particularly pronounced in today’s intensive work environment and remote work settings.

A research team led by Sir Run-Run Shaw Hospital, Zhejiang University School of Medicine, has published a comprehensive review in ExRNA that sorts out the diverse roles of extracellular vesicle-associated RNAs (EV-RNAs) in the development and progression of inflammatory bowel disease (IBD). By integrating the latest findings from multi-omics studies and animal experiments, the review points out that EV-RNAs can serve as non-invasive biomarkers for early IBD detection and disease monitoring, and also hold great potential as targets for next-generation targeted therapies. This work provides a solid theoretical basis for advancing personalized precision treatment for the millions of IBD patients worldwide suffering from this chronic recurrent gastrointestinal disorder.

Researchers in Lithuania have identified a promising new approach to cartilage regeneration using extracellular vesicles derived from menstrual blood stromal cells. Their study shows that these tiny cell-released particles can improve cartilage cell function, slow tissue degradation, and stimulate regenerative processes even in older cartilage cells with reduced healing capacity. The findings suggest a potential future cell-free therapy for osteoarthritis, a condition affecting more than 600 million people worldwide. To enhance the stability and delivery of these vesicles, the interdisciplinary team is also developing biomimetic scaffolds that protect the vesicles and release them gradually within the joint. The research highlights both the therapeutic potential of menstrual blood-derived biological material and the importance of combining biomaterials, cell biology, and engineering in regenerative medicine.

Precise intracellular transport is essential for neuronal function, yet the exact mechanism of selective cargo delivery by motor proteins remains unclear. Now, researchers from Japan have reported that distinct kinesin-2 motor protein assemblies have specific cargo preferences. Their report mentions that the KIF3B/B/KAP3 kinesin complex specifically transports TRIM46 to the axon initial segment of a neuron. This discovery reveals the underlying mechanism of transport specificity in neurons and may help understand transport defect-related disorders.

Environmental enrichment (EE), which involves a combination of voluntary exercise and social interaction has been known to improve poststroke functional recovery. However, its effect on chronic inflammation and white matter pathology remains elusive. Now, a new study reveals that EE improves sensorimotor recovery after stroke while weakening correlation of infarct size with chronic inflammation and myelin damage. It also identifies TREM2-positive microglia in white matter as a potential cellular signal associated with improved functional recovery.

Low aerobic fitness and muscle weakness increase the risk of complications and death in people with heart failure. This systematic review found that combined aerobic and resistance training improves aerobic fitness and muscle strength more than aerobic training alone. This advantage remained even when total exercise time was matched. Adding resistance training may therefore be an effective strategy to enhance aerobic fitness, build muscle strength, and potentially improve prognosis in patients with heart failure.
