|''' How to interpret [[hydrogen peroxide]] fluxes in [[permeabilized muscle fibers]] (pfi) in relation to the high oxygen regime used? '''<br>
|''' 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>
In the absence of malate, accumulation of Acetyl-CoA inhibits FAO. <br>

|''' What is the difference between Amplex UltraRed assay and the use of probes like MitoSOX?'''<br>
|'''Antitumoral properties of triterpenic acid functionalized gold nanoparticles arise from decreasing mitochondrial respiration''' <br>
Amplex UltraRed assay is specific for H<sub>2</sub>O<sub>2</sub>, while MitoSOX is specific for O<sub>2</sub><sup>•-</sup> but not for other [[Reactive oxygen species|reactive oxygen species]] or [[Reactive nitrogen species|reactive nitrogen species]]. When the Amplex UltraRed assay is performed in the presence of exogenously added [[superoxide dismutase]], O<sub>2</sub><sup>•-</sup> will be dismutated to H<sub>2</sub>O<sub>2</sub>, which will then be measured in the assay.<br>

|''' Why it is necessary to perform multiple  H<sub>2</sub>O<sub>2</sub> calibrations when running the [[Amplex UltraRed]] assay?'''<br>
We recommend performing H<sub>2</sub>O<sub>2</sub> calibration of the Amplex UltraRed assay before sample addition (in DatLab 7.4: AmR calibration.DLP), after sample addition and multiple times during the experiment (in DatLab 7.4: see DL-Protocols for AmR, https://www.bioblast.at/index.php/MitoPedia:_SUIT#SUIT_A_FluoRespirometry:_recommended_protocols).  Multiple calibrations are needed because the sensitivity of the Amplex UltraRed assay to H<sub>2</sub>O<sub>2</sub> changes. This change may be due to: 1) experimental time, 2) changes in the optical properties, 3) radical scavenging capacity of the sample, and 4) concentration of the accumulating resorufin (UltroxRed in the case of Amplex UltraRed).<br>

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

- » FAT4BRAIN FAO-mito-CNS platform «

O2k-Brief alert

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.

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.

O2k-Open Support alert

  • Examples:
O2k-Open SupportInfo: take care Does your polarographic oxygen sensor (POS) need a deep clean?

A POS with a very dark anode might need several rounds of ammonia cleaning, possibly including prolonged exposure overnight to restore performance specifications.
- »POS service«
- communicated by »Cecatto Cristiane« and »Leo Elettra«

O2k-Open SupportWarning: loss of data Did you know that a humid environment and/or liquid spillage may lead to a high raw POS signal [V]?

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.

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.
