Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Vortex Assisted Extraction for Propylparaben Analysis in Cosmetics
Propylparaben is an ester of para-hydroxybenzoic acid and commonly used as a preservative in the cosmetics, pharmaceuticals and food products. However, several recent reports demonstrated that paraben possesses an estrogenic activity and causes cancer ...

An on-line solid phase extraction procedure for the routine quantification of urinary methylmalonic acid by liquid chromatography-tandem mass spectrometry [PDF]
Background: The goal of this study was to develop and to validate an improved isotope-dilution-liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantification of methylmalonic acid (MMA) in urine.

Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

The ammonolysis of esters in liquid ammonia
The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Liquid-liquid extraction of barium with DEPHA: chemical equilibrium
The objective of this work was to evaluate a liquid - liquid extraction process to separate barium in aqueous phase by means of an organic phase consisting of DEPHA (bis-2-ethylhexyl phosphate) in kerosene and isopropyl alcohol as modifying agent ...

Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Palm stearin-based mono-diacylglycerols (MDAGs) are food emulsifiers that have not yet been widely developed. Monoacylglycerol (MAG) and diacylglycerol (DAG) are the predominant components of MDAGs.
