Bioblast alert
Bioblast alert messages are prepared by the Bioblast editorial board to draw attention to specific topics on the Bioblast wiki. Bioblast alert is for information purposes only, it is not intended to be an advertisement. Topics submitted by the general scientific community are very welcome.
Bioblast alert 2011(02): 2011-11-17
- O2k-Publication: 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. (Scientific service)
- Uncoupled, non-coupled, 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.
Bioblast alert 2011(01): 2011-11-11
- O2k-Fluorometry Workshop IOC66: 2012-03-15 to 16. OROBOROS INSTRUMENTS, Innsbruck, Austria. The first series of the O2k-Fluorescence Module will be delivered in April 2012, for orders received by end of January 2012.
- O2k-Publication: 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?
- ETS capacity plays a key role in such analyses, which cannot be achieved quantitatively without careful uncoupler titrations. (Scientific service)
- Basal respiration - term of the month: a hallmark of high-resolution respirometry is a matching high-resolution terminology.
