Researchers have discovered a biochemical oxygen sensing system conserved across biological kingdoms, which allows both plant and animal cells to sense and respond appropriately to changes in oxygen levels - an ability central to the survival of most forms of life. The newly identified enzymatic oxy more
A new invention will open the doors for an entirely new way of measuring properties within liquids. The invention, a sol-gel matrix, will make it possible to perform measurements that are reliable, incredibly rapid and can be conducted over extended periods of time. The development will be a boon fo more
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxy more
Abstract Over 17 million km2 of land is affected by soil flooding every year, resulting in substantial yield losses and jeopardizing food security across the globe. A key step in resolving this problem and creating stress-tolerant cultivars is an understanding of the mechanisms by which plants sens more
Hypoxia is a common feature of solid tumors. Prolyl hydroxylase enzymes (PHD1–3) are molecular oxygen sensors that regulate hypoxia-inducible factor activity, but their functions in metastatic disease remain unclear. Here, we assessed the significance of PHD enzymes during the metastatic spread of c more
Abstract Transient ischemia leads to tolerance to subsequent protracted ischemia. This “ischemia preconditioning” results from the induction of numerous protective genes, involved in cell metabolism, proliferation and survival, in antioxidant capacity, angiogenesis, vascular tone and erythropoie more
