Chemistry / Is halogenation of alkynes with propylene glycol possible?

« on: 27/12/2023 20:02:27 »

Propylene glycol (PG) is a electrophilic solvent (Lewis base) found in most vaping liquids. Furthermore PG is a secondary alcohol (ether) containing a free hydrogen-bond, thus participating in nucleophilic attacks in presence of oxygen and a halogen (ie: fluoride), giving yield to fluorocarbons derivatives. Hence, ether-based fluoroalkylation seem likely to produce water-vapor and a enol tautomer with potentially toxic effects to human health....

Consequently, can PG be used as a Lewis solvent for producing fluorocarbons (fluoroalkynes) in presence of an halogen such as fluoride?

Thank you in advance,

New Theories / What is safety conditioning?

« on: 11/04/2021 23:33:24 »

Hi all,

Compulsory mask wearing is a subliminal method to stimulate stress-mediated dopamine transmission in the striatum thereby enhancing post-synaptic D2 receptors connectivity from the central amygdala and nucleus accumbens. This extracellular dopamine activity in the striatum may prime neuronal (chemo)signaling associated to active avoidance conditioning, a Pavlovian type of instrumental learning.

Consequently, is dopamine-mediated avoidance conditioning a reversible fear-extinction learning paradigm?

What do you think?

Just Chat! / How to create a lipid peroxidation assay?

« on: 11/04/2021 22:56:21 »

Hi all,

I am trying to design an experimental assay to verify whether it is possible to oxidize glucagon synthesis in vitro using H2O2 reagent and plain water solution. How may i confirm glucagon elimination when using H2O2 as a oxidative reagent in a water solution?

What do you think?
