Previously, following derivatization to their 2-nitrophenylhydrazide (2-NPH) derivatives, fatty acid (FA) abundances have been evaluated using high-performance liquid chromatography (HPLC). Although the method was sensitive, resolution was insufficient for many of the biologically important FAs. We have developed an enhanced separation of 24 FAs by use of different column temperature, stationary phase, and mobile phase gradient conditions. We applied this method to analysis of mouse skeletal muscle phospholipid and triglyceride. This further development of the chromatographic separation of 2-NPH FAs may lead to greater utility of this HPLC approach.

A novel bacterium, designated 19SA41, was isolated from the air of the Icelandic volcanic island Surtsey. Cells of strain 19SA41 are Gram-stain-negative, strictly aerobic, non-motile rods and form pale yellow-pigmented colonies. The strain grows at 4-30 °C (optimum, 22 °C), at pH 6-10 (optimum, pH 7.

To regulate brain function, peripheral compounds must traverse the blood-brain barrier (BBB), an interface between the brain and the circulatory system. To determine whether specific transport mechanisms are relevant for sleep, we conducted a BBB-specific inducible RNAi knockdown (iKD) screen for genes affecting sleep in . We observed reduced sleep with knockdown of solute carrier , a carnitine transporter, as determined by isotope flux.

Ferroptosis is an iron-dependent form of programmed cell death (PCD) associated with lipid membrane peroxidation. It has gained attention in cancer research because some tumor cells that are resistant to other forms of PCD are sensitive to ferroptosis. Despite the significant amount of research on ferroptosis, the list of known inducers remains limited, creating opportunities to discover new compounds with clinical potential.

NAFLD is one of the most common and rapidly increasing liver diseases. Procyanidin C1 and procyanidin C2, B-type trimeric procyanidins, show beneficial effects on regulating lipid metabolism. However, the mechanism underlying these effects remain elusive.
