PERFORMANCE OF PARALLEL SURGE ARRESTERS

Journal of Energy - Energija, 2022
The operation of parallel surge arresters can improve energy absorption capability if the arresters are   similar and are installed close to each other. However, it has been reported that any small difference in   the individual V-I characteristics can lead to unbalance in current sharing. When the arresters are   installed some distance away from each

Sonoepigenetic Modification Mechanoprimes Early Osteogenic Commitment in Mesenchymal Stem Cells

Advanced Science, EarlyView.
Brief 10 min bursts of high frequency (10 MHz) vibrational mechanostimulation to stem cells are shown to activate their epigenetic machinery to condition their differentiation down an osteogenic lineage within just 3 days, which is much earlier than that with other forms of mechanostimuli, and without requiring any biochemical additives. Abstract Cells

Esketamine/Ketamine: Dual‐Action Mechanisms and Clinical Prospects beyond Anesthesia in Psychiatry, Immunology, and Oncology

Advanced Science, EarlyView.
Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.

Mitochondrial Adaptation to Mechanical Stress in Cardiac Ageing and Disease

Advanced Science, EarlyView.
Mechanical forces shape the heart's energy factories. This review explores how mitochondria in cardiac cells sense and respond to biomechanical stress, altering their structure, positioning, and metabolism. By linking mechanical cues to mitochondrial adaptation, the article highlights pathways driving heart disease and points to new strategies for ...
