The airway epithelium, which lines the conducting airways, is central to the defense of the lungs against inhaled particulate matter and pathogens such as SARS-CoV-2, the virus that causes COVID-19.Recognition of pathogens results in the activation of an innate and intermediate immune response which involves the release of cytokines and chemokines
Free hemoglobin (fHb) may induce vasoconstriction by scavenging nitric oxide.It may increase in older blood units due to storage lesions.This study evaluated whether old red blood cell transfusion increases plasma fHb in sepsis and how the microvascular response may be affected.This is a secondary analysis of a randomized study.Twenty adult septic
This study applied a nuclear technique based on thermalized neutrons (TNs) to estimate maize yield losses arising from water shortage.Crop biomass consists of water, and light hydrogen (1H) existing in water slows down fast neutrons.Hence, TNs can be probably suitable predictors to determine crop losses.A greenhouse experiment was performed to eval
Glycosaminoglycans (GAGs) are a family of linear and negatively charged polysaccharides that exist ubiquitously on the human cell surface as well as in the extracellular matrix.GAGs interact with a wide range of proteins, including proteases, growth factors, cytokines, chemokines and adhesion molecules, enabling them to mediate many physiological p
