Shining new light on mammalian diving physiology using wearable near-infrared spectroscopy [PDF]
, 2019 Investigation of marine mammal dive-by-dive blood distribution and oxygenation has been limited by a lack of non-invasive technology for use in freely diving animals.

COVID-19: A Possible Contribution of the MAPK Pathway
Biomedicines, 2023 Background: COVID-19 is characterized by an uncontrolled inflammatory response with high pro-inflammatory cytokine production through the activation of intracellular pathways, such as mitogen-activated protein kinase (MAPK).

Photoplethysmographic imaging of hemodynamics and two-dimensional oximetry [PDF]
Известия Саратовского университета. Новая серия: Физика, 2022 Background and Objectives: A review of recent papers devoted to actively developing methods of photoplethysmographic imaging (PPGI) of blood volume pulsations in vessels and non-contact two-dimensional oximetry on the surface of the human body is carried

The oxygen trail: tissue oxygenation [PDF]
British Medical Bulletin, 1999 Aerobic cellular respiration depends on the efficient supply of oxygen and substrate to the mitochondria. There is an oxygen cascade from the environment to the subcellular environment. Efficient oxygen delivery depends on the coordinated interaction between the respiratory and circulatory systems.

Three dimensional optical imaging of blood volume and oxygenation in the neonatal brain [PDF]
, 2006 Optical methods provide a means of monitoring cerebral oxygenation in newborn infants at risk of brain injury. A 32-channel optical imaging system has been developed with the aim of reconstructing three-dimensional images of regional blood volume and ...

Constraining the rise of oxygen with oxygen isotopes [PDF]
Nature Communications, 2019 AbstractAfter permanent atmospheric oxygenation, anomalous sulfur isotope compositions were lost from sedimentary rocks, demonstrating that atmospheric chemistry ceded its control of Earth’s surficial sulfur cycle to weathering. However, mixed signals of anoxia and oxygenation in the sulfur isotope record between 2.5 to 2.3 billion years (Ga) ago ...

Triazole-Directed Pd-Catalyzed C(sp2)–H Oxygenation of Arenes and Alkenes [PDF]
, 2016 Selective Pd-catalyzed C(sp2)–H oxygenation of 4-substituted 1,2,3-triazoles is described. Unlike previous metal-catalyzed C–H functionalization events, which preferentially occur at the activated heterocyclic C–H bond, the regioselective oxygenation of ...
