Background Mechanical stress on the heart is commonly considered the sole stimulus explaining the synthesis and release of ...

Antibiotics increase the gut oxygen levels and favor growth of harmful fungi. Chemically restoring intestinal gut hypoxia ...

2006). Using DNA microarrays, these investigators examined changes in gene expression at a global level in different cell types. In looking for a signature of hypoxia, the researchers compared ...

Yet for decades the precise workings were largely a mystery. Scientists knew that in low oxygen situations, or hypoxia, cells trigger a cascade of physiological events to restore oxygen ...

Haemostasis (clot formation) halts the bleeding, and the body quickly forms a blood clot in response to injury. Inflammation ...

Their paper is published in the European Heart Journal. "Microvascular over-dilation causes hypoxia and cell shrinkage even in healthy muscle," Korpisalo notes. In light of the new findings ...

This condition, which often occurs during medical events such as heart failure, can also cause acute altitude sickness; ...

developed a targeted nanozyme delivery system by identifying specific cell surface targets in hypoxic lesions of NPC, effectively enhancing the radiosensitivity of NPC through hypoxia-targeted ...

By lowering the media volume, and thus increasing the pericellular oxygen, Tan observed lowered hypoxia signaling and transcriptional rewiring that recapitulated a healthier adipocyte cell model.
