|''' Measuring fatty acid oxidation (FAO)-linked respiration requires a low concentration of malate '''<br>
In pfi, [[reactive oxygen species]] (ROS) production may be artificially increased by high oxygen pressures, but high oxygen concentrations are needed to avoid oxygen limitation. Consequently, pfi may not be an optimum model for studies of ROS production.<br>

OXPHOS capacity allows you to measure maximal respiratory capacity in the OXPHOS state in the presence of saturating concentration of ADP, P<sub>i</sub>, fuel substrates and O<sub>2</sub>. However, State 3 can lead to underestimation of OXPHOS capacity and overestimation of [[excess E-P capacity]] creating experimental artefacts. <br>

|''' "In respirometric studies on blood cells, the purity of cell preparation should always be emphasized and documented." '''<br>
Multiple calibration is needed because the [[sensitivity]] of the Amplex UltraRed assay towards H<sub>2</sub>O<sub>2</sub> changes during the experiment. This change may be the function of: 1) experimental time, 2) changes in the optical properties, 3) radical scavenging capacity owing to the sample, and 4) concentration of the accumulating resorufin (UltroxRed in the case of Amplex UltraRed). Therefore, it is recommended to perform H<sub>2</sub>O<sub>2</sub> calibration before sample addition, after sample addition and multiple times during the experiment. <br>

Measuring fatty acid oxidation (FAO)-linked respiration requires a low concentration of malate

In the absence of malate, accumulation of Acetyl-CoA inhibits FAO.

FAT4BRAIN
A FAO-mito-CNS platform to help fatty acid-related respiration measurements was developed in the FAT4BRAIN project

O2k-Brief alert

  • Example:
O2k-brief repository Antitumoral properties of triterpenic acid functionalized gold nanoparticles arise from decreasing mitochondrial respiration
  • Mioc M, Mioc A, Racoviceanu R, Ghiulai R, Prodea A, Milan A, Barbu Tudoran L, Oprean C, Ivan V, Șoica C (2023) The antimelanoma biological assessment of triterpenic acid functionalized gold nanoparticles. »Bioblast link«

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"
  • Temelie M, Talpur R, Dominguez-Prieto M, Dantas Silva A, Cenusa C, Craciun L, Savu DI, Moisoi N (2023) Impaired integrated stress response and mitochondrial integrity modulate genotoxic stress impact and lower the threshold for immune signalling. »Bioblast link«

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.

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.

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.
