Bacterial sensors of oxygen.
The concentration of molecular oxygen (O(2)) began to increase in the Earth's atmosphere approximately two billion years ago. Its presence posed a threat to anaerobes but also offered opportunities for improved energy conservation via aerobic respiration. The ability to sense environmental O(2) thus became, and remains, important for many bacteria, both for protection and switching between anae...
متن کاملIndicators for optical oxygen sensors
Continuous monitoring of oxygen concentration is of great importance in many different areas of research which range from medical applications to food packaging. In the last three decades, significant progress has been made in the field of optical sensing technology and this review will highlight the one inherent to the development of oxygen indicators. The first section outlines the bioanalyti...
متن کاملOxygen sensors in hypoxic pulmonary vasoconstriction.
Hypoxic pulmonary vasoconstriction (HPV) is an essential mechanism adapting lung perfusion to regional ventilation. Perturbations to HPV, such as those occurring in pneumonia, acute respiratory distress syndrome and liver failure, can result in arterial hypoxemia. Under conditions of general hypoxia, HPV increases pulmonary vascular resistance and thus causes acute pulmonary hypertension. Despi...
متن کاملOxygen sensors: Materials, methods, designs and applications
Advancement of gas sensor technology over the past few decades has led to significant progress in pollution control and thereby, to environmental protection. An excellent example is the control of automobile exhaust emissions, made possible by the use of oxygen gas sensors. Since early 1970’s there have been sustained studies on oxygen sensors and has led to development of sensors for various a...
متن کاملOxygen sensors and neuronal adaptation to ischemia
Hypoxia research is in the focus, as three of its pioneers receive the Lasker Prize 2016 for their discovery of hypoxia-inducible transcription factors (HIFs) and prolyl-4-hydroxlase domain proteins (PHDs) as cellular oxygen sensors [1]. HIFs are heterodimers consisting of a labile α and a stable β unit. In the presence of molecular oxygen the α subunit is hydroxylated by PHDs leading to immedi...
