A Comparative Study of MALDI MSI Versus DESI MSI Applied to Questioned Document Examination

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale In forensic investigations, questioned document examination (QDE) provides critical information for document authentication and the detection of forgeries. Conventional QDE approaches often require separate analyses of inks and of any potential fingerprints.

Lysophospholipids in the limelight [PDF]

The Journal of Cell Biology, 2002
Lysophosphatidic acid (LPA) is a serum phospholipid that evokes growth factor–like responses in many cell types through the activation of its G protein–coupled receptors. Although much is known about LPA signaling, it has remained unclear where and how bioactive LPA is produced. Umezu-Goto et al.

x‐Ray Structure of Streptomyces avermitilis Phospholipase D Reveals a Ca2+‐Stabilized Expanded Active‐Site Cleft Adapted for Phospholipid Binding

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 9, Page 1543-1550, September 2026.
ABSTRACT Phospholipase D (PLD) catalyzes the hydrolysis of phospholipids to generate phosphatidic acid and free head groups such as choline. Among bacterial PLD enzymes, Streptomyces chromofuscus PLD (SchPLD), a member of the alkaline phosphatase D (PhoD) superfamily, exhibits unique Ca2+‐dependent phospholipase activity.

Unlabeled lysophosphatidic acid receptor binding in free solution as determined by a compensated interferometric reader

Journal of Lipid Research, 2020
Native interactions between lysophospholipids (LPs) and their cognate LP receptors are difficult to measure because of lipophilicity and/or the adhesive properties of lipids, which contribute to high levels of nonspecific binding in cell membrane ...

Systems‐Level Plant Responses Reveal Pseudomonas‐Mediated Growth Promotion in Brachypodium Under Nitrogen Limitation

Plant, Cell &Environment, Volume 49, Issue 9, Page 6396-6412, September 2026.
ABSTRACT Plant growth–promoting bacteria can enhance plant performance under nutrient limitation, yet the underlying plant molecular responses remain incompletely resolved. We investigated growth promotion by Pseudomonas koreensis in Brachypodium distachyon under contrasting nitrogen (N) regimes using time‐resolved phenotyping, elemental analysis ...

Network Pharmacology Combined With Metabonomics and Transcriptomics Reveals the Mechanism of Rubus Chingii Hu in Alleviating Nephrotoxicity Caused by Tripterygium Glycosides Tablet

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Flow chart of RCH to improve TGT‐induced nephrotoxicity. ABSTRACT Researches on Tripterygium glycosides tablets (TGT) often overlook renal toxicity from prolonged use. Rubus chingii Hu (RCH) is beneficial to kidney health and has an unclear role in reducing nephrotoxicity.

Lysophospholipid receptors in drug discovery [PDF]

Experimental Cell Research, 2015
Lysophospholipids (LPs), including lysophosphatidic acid (LPA), sphingosine 1-phospate (S1P), lysophosphatidylinositol (LPI), and lysophosphatidylserine (LysoPS), are bioactive lipids that transduce signals through their specific cell-surface G protein-coupled receptors, LPA1-6, S1P1-5, LPI1, and LysoPS1-3, respectively.

Myocardial Lipid Metabolism Imbalance: The Pathological Core and Novel Diagnostic‐Therapeutic Directions of Cardiovascular Diseases

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
In cardiac cells, Plin5/AMPK regulate lipid homeostasis; excess CD36‐mediated uptake drives lipotoxicity, mitochondrial dysfunction, and CVDs (e.g., heart failure). Biomarkers (ApoB/ApoA‐1) and therapies (SGLT2 inhibitors) target this cascade. ABSTRACT Cardiac lipid metabolism is fundamental to myocardial energy homeostasis, with fatty acid oxidation ...
