|''' Why is it important to perform respirometry with permeabilized muscle fibers (pfi) under a high [O<sub>2</sub>] regime? '''<br>
Long diffusion distances in the pfi result in an O<sub>2</sub> diffusion limitation, which is overcome by increasing the O<sub>2</sub> partial pressure inside the chamber. Proper instrumental background correction is a must and O<sub>2</sub> dependence of ROS production should be considered.  <br>

|''' Living cells or intact cells? '''<br>
|''' What is the effective concentration of digitonin for complete plasma membrane permeabilization?'''<br>
Living cells are frequently labelled as ''intact cells'' in the sense of the total cell count, but ''intact'' may suggest dual meanings of viable or unaffected by a disease or mitochondrial injury.   <br>
It needs to be determined for each cell type and digitonin batch. The SUIT protocol SUIT-010 was designed to evaluate the optimum digitonin concentration to permeabilize the plasma membrane. <br>

|''' Is fatty acid oxidation (FAO) considered as CI- or CII-driven respiration? '''<br>
|''' How do I determine the optimal oligomycin concentration for my assay?'''<br>
Neither. FAO generates acetyl-coA, which will enter the TCA cycle, and FADH<sub>2</sub>, resulting in simultaneous electron transfer into the Q-junction through the electron transferring flavoprotein complex (CETF) and Complex I. <br>
Perform the oligomycin titration test, and adjust your oligomycin concentration to minimize the inhibition of ET respiration. <br>

O2k-Publications alert

  • Example:
O2k-Publications in the MiPMap "Mitochondria–nucleus communication and its integration within the maintenance of cellular homeostasis constitute key determinants of cellular fate and organism health in the context of cellular stress, homeostasis perturbation, and disease"

Guidelines to update a reference

When creating an O2k-Publication/Brief alert, it is the responsibility of the author to check if the reference is accordingly to the correct guidelines:

Reference example.png

Correct format for a person called “First Name Surname”:
In the gray box should be “Surname FN” - From where references to be used as O2k-Publication/Brief alerts are copied from.

Gray box reference.png

In the links should be “ Surname First N”

Authors names links reference.png

How to edit:
A) Check if all authors with profiles in Bioblast (blue links) have their profiles with full name. If they have, proceed to next step (B). If not, you need to move it following the steps “How to move a profile” below.
B) Click in “Edit with form”.
C) The gray box is edited in “Reference” and the links are changed in “Author(s)”. Change it accordingly and click in “save page” at the end of the page.

Editing reference.png

How to move a profile (instructions sent by Marija):

So let’s take for example my page: Beno M [1]

As you can see there is a redirect from Beno Marija to Beno M. What has to be done is to switch the content of those pages. Here are the steps:
1. Go to e.g. “Beno M” on edit
2. Click on “Move”
3. Change the new title to the full name of the person. In my case it will be Beno M to Beno Marija

BenoMreference.jpg

4. Now it should look like that:

BenoMarijaReference.png

5. Click on “Move” and leave all the ticked boxes
6.Done
After that you can continue in step B.
If you have any doubt you can contact Cristiane, Marija or Mario.

Under discussion

This one needs an update of the Bioblast page and clarification of MiPNet06.03

O2k-Open SupportInfo: improve Did you enter the correct oxygen solubility factor in DatLab?

The oxygen solubility factor of the incubation medium, FM, expresses the effect of the salt concentration on oxygen solubility relative to pure water. The correct oxygen solubility factor of your experimental medium or buffer needs to be entered in DatLab for proper calculation of the oxygen concentration.
- »Oxygen solubility factor«
- communicated by »Schmitt Sabine« and »[[ ]]«

This one needs a BioBlast link:

O2k-Open SupportInfo: improve When filling in the volume of uncoupler in the DatLab mark or the excel template, should one enter the total volume added or the volume to get to the highest flux?

The volume added until the mark, equal to the highest flux, should be entered. Anything titrated after this mark should be summed to the other volumes before the next mark because this will be considered to calculate the sample dilution.
- »LINK and O2 flux analysis with DatLab 7.4«
- communicated by »Cardoso Luiza« and »[[ ]]«


Removed for correction

  • Nov-30 Mo
O2k-Open SupportInfo: improve Noisy oxygen signal? Check the OroboPOS and OroboPOS-Connector to clean electrical connections.

Contaminating grease, salt crystals and moisture can be removed with a dry paper cloth or a paper cloth moistened with water and then absolute ethanol.
- »Cleaning the electrical connections« 
- communicated by »Schmitt Sabine« and »Komlodi Timea«

WGT recommended not to use water for cleaning. Erich introduced water for cleaning to remove salt crystals.


O2k-Open SupportWarning: loss of data Do you perform the leaky chamber test after chamber assembly?

An unnoticed leak from the chamber may affect your data, therefore we recommend performing the Leaky chamber test - especially after chamber reassembly.
- »Leaky chamber test« and » https://intern.oroboros.at/index.php/Overnight_test_after_O2k-chamber_assembly«
