Calprotectin Is a Circulating Biomarker and Potential Therapeutic Target for Sarcopenia in Chronic Obstructive Pulmonary Disease

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Sarcopenia, an important complication of chronic obstructive pulmonary disease (COPD), is significantly associated with increased mortality. Systemic inflammation is an important trigger of COPD‐related skeletal muscle dysfunction. Calprotectin is a damage‐associated molecular pattern involved in the inflammatory response, but its ...

Synergistic Plasmonic‐Thermoelectric Enhancement in Semiconducting Carbon Nanotubes for Infrared Light Detection

open access: yesSmall Structures, Volume 7, Issue 2, February 2026.
Purified semiconducting carbon nanotube films with controlled amphoteric doping exhibit a synergistic enhancement of plasmonic absorption and thermoelectric response, thereby enabling high‐sensitivity infrared (IR) light detection. By tuning electronic and thermal transport simultaneously, an 11‐fold improvement in photothermoelectric response is ...
