The timing of life on Earth is remarkable: between individuals of the same species, a highly similar temporal pattern is observed, with shared periods of activity and inactivity each day. At the ...

The ability to sense and respond to changes in cellular oxygen levels is critical for aerobic organisms and requires a molecular oxygen sensor. The prototypical sensor is the oxygen-dependent enzyme ...

Mitophagy impairment and oxidative stress are cardinal pathological hallmarks in Parkinson’s disease (PD), a common age-related neurodegenerative condition. The specific interactions between mitophagy ...

The HIF oxygen sensing pathway. Under normoxic conditions, proline (P) and asparaginyl (N) residues in HIFαs are first recognized and degraded by activated prolyl hydroxylases (PHDs) and asparaginyl ...

Step 1: Aerobic ammonia oxidizing (AerAOBs) bacteria use oxygen (O2) to convert a portion of the ammonia (~55%) into nitrite (NO2-N). This step consumes Dissolved Oxygen (DO) and alkalinity. Which ...

We introduce for the first time a new product line able to make high accuracy measurements of a number of water chemistry parameters in situ: i.e., submerged in the environment including in the deep ...

Intracellular sensors of essential metals are upstream homeostatic responders that detect changes in metal levels to initiate protective responses. But, unlike other metals, a mammalian manganese (Mn) ...

Hypoxia promotes renal damage and progression of chronic kidney disease (CKD). The erythrocyte is the only cell type for oxygen (O 2) delivery. Sphingosine 1-phosphate (S1P)—a highly enriched biolipid ...

Portland cement is an essential ingredient for the construction industry, used to make concrete and mortar. There are more than 2,000 active cement plants around the world producing over 3.5 billion ...
