Objective: In this context, our study aimed to ascertain whether the esterification of 24-hydroxycholesterol, a process heavily affected by oxidative stress, is altered in ALS.

Methods: The study examined the level of 24-hydroxycholesteryl esters in cerebrospinal fluid and plasma of 18 ALS patients by spectroscopic technique as Ultra-high performance liquid chromatography mass spectrometry (UPLC-MS).

Results: The level of 24-hydroxycholesteryl esters in cerebrospinal fluid was found to be lower as the brain-blood barrier was damaged.

Polyunsaturated fatty acids (PUFA) are fundamental building materials for cells and play crucial function as signaling molecules. When PUFA are used as substrates for non-enzymatic or enzymatic reactions and gut microbiota metabolism, they can generate electrophilic derivatives (called Reactive Lipid Species, RLS) that promptly form adducts with nucleophilic molecules. RLS participate in several signaling pathways, including the activation of the nuclear factor erythroid 2-related factor 2 (Nrf2) pathway, which is the key mechanism in the maintenance of redox, metabolic and protein homeostasis, as well as the regulation of inflammation.

Background: Traumatic caudal elbow luxation is an uncommon injury and it is rarely reported in the cat. Closed reduction is considered in early instance but open reduction and stabilization should be evaluated if the joint cannot be reduced or if gross instability persist.

Case Description: This case report described two Domestic Shorthaired cats referred for monolateral forelimb non-weight bearing lameness caused by trauma.

24-hydroxycholesterol (24OH-C) is synthesized almost exclusively in neurons. This oxysterol is mostly present as ester form in both cerebrospinal fluid and plasma. The enzyme lecithin-cholesterol acyltransferase esterifies 24OH-C in the brain, and the level of 24OH-C esters in cerebrospinal fluid was found to be correlated with the level of 24OH-C esters in plasma.
