- A key question on the separation of qualitative versus quantitative change of mitochondrial function is addressed in a new O2k-Publication. Does training induce mild uncoupling? Are sedentary humans healthy controls?
- ET capacity plays a key role in such analyses, which cannot be achieved quantitatively without careful uncoupler titrations.
- Basal respiration - term of the month: a hallmark of high-resolution respirometry is a matching high-resolution terminology.

- Heart failure and mitochondrial dysfunction. Increased OXPHOS capacity after cold preservation of the human heart – a paradox resolved by a dyscoupling mechanism.
- Tissue storage on ice is possible for limited periods of time (several hours) with preservation of mitochondrial respiratory function, as evaluated with SUIT protocols.
- Uncoupled, noncoupled, dyscoupled - term of the week: a hallmark of high-resolution respirometry is a matching high-resolution terminology.
- Evaluate an example of low-resolution terminology: Uncoupling was studied in stressed cells by measurement of coupled respiration, evaluation of uncoupled respiration after inhibition with oligomycin, and FCCP titration to quantify uncoupled respiration.
