Hypercapnia Effects on Lung Function

open access: yesComprehensive Physiology, Volume 16, Issue 1, February 2026.
CO2 is a signaling molecule that disrupts alveolar fluid clearance and ion transport, impairs alveolar repair, and promotes mitochondrial and endoplasmic reticulum dysfunction. It suppresses innate immunity, host defense, and inflammation, while increasing airway contractility.

Association Between Abnormal DNA Methylation and Altered Transcriptome in Muscle Five Years After Critical Illness

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Critically ill patients requiring intensive care unit (ICU) admission suffer from muscle weakness that persists for years. Recently, altered RNA expression was documented in muscle of former ICU patients 5 years after critical illness that suggested disrupted mitochondrial function, disturbed lipid metabolism and fibrosis, of which ...

High‐Throughput Screen of NPQ in Sorghum Shows Highly Polygenic Architecture of Photoprotection

open access: yesPlant-Environment Interactions, Volume 7, Issue 1, February 2026.
ABSTRACT Natural genetic variation in photosynthesis and photoprotection within crop germplasm represents an untapped resource for crop improvement. Sorghum bicolor (sorghum) is one of the world's most widely grown crops, yet the genetic basis of photoprotection in sorghum is not well understood.
