L. (purslane) extract ameliorates intestinal inflammation in diet-induced obese mice by inhibiting the TLR4/NF-κB signaling pathway.

Front Pharmacol

January 2025

State Key Laboratory of Quality Research in Chinese Medicine, Institute of Chinese Medical Sciences, University of Macau, Macau SAR, China.

Background: L. (purslane) is a dietary plant and a botanical drug with antioxidant, antidiabetic, and anti-inflammatory activities. However, the effects of purslane against intestinal-inflammation-associated obesity are yet to be studied.

The abrupt and substantial elevation of intraocular pressure (IOP) in acute glaucoma induces retinal ischemia/reperfusion (I/R) injury, resulting in progressive retinal ganglion cell (RGC) death and irreversible visual impairment. PANoptosis, a form of regulated cell death consisting of pyroptosis, apoptosis and necroptosis, is reported to be involved in high IOP-induced RGC death. However, the precise mechanisms of RGC death remain unclear, and neuroinflammation is considered to play a vital role.

Ether bond-modified lipid nanoparticles for enhancing the treatment effect of hepatic fibrosis.

Int J Pharm

January 2025

National Advanced Medical Engineering Research Center, China State Institute of Pharmaceutical Industry, 285 Gebaini Road, Shanghai 201203, China. Electronic address:

Lipid nanoparticle (LNP)-mediated RNA delivery holds significant potential for the treatment of various liver diseases. Ionizable lipids play a crucial role in the formulation of LNPs and directly influence their delivery efficiency. In this study, we introduced an innovative concept by incorporating an ether bond into the hydrophobic tail of ionizable lipids for the first time.

Mitigating matrix effects in oil and gas wastewater analysis: LC-MS/MS method for ethanolamines.

Environ Sci Process Impacts

January 2025

Massachusetts Institute of Technology, Department of Civil and Environmental Engineering, Parsons Laboratory, 15 Vassar Street, Cambridge, Massachusetts 02139, USA.

The high salinity and organic content in oil and gas wastewaters can cause ion suppression during liquid chromatography mass spectrometry (LC/MS) analysis, diminishing the sensitivity and accuracy of measurements in available methods. This suppression is severe for low molecular weight organic compounds such as ethanolamines (, monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), -methyldiethanolamine (MDEA), and ,-ethyldiethanolamine (EDEA)). Here, we deployed solid phase extraction (SPE), mixed-mode LC, triple quadrupole MS with positive electrospray ionization (ESI), and a suite of stable isotope standards (, one per target compound) to correct for ion suppression by salts and organic matter, SPE losses, and instrument variability.

Introduction: Neuroinflammation derived from the activation of the microglia is considered a vital pathogenic factor of Alzheimer's Disease (AD). T-006, a tetramethylpyrazine derivative, has been found to alleviate cognitive deficits via inhibiting tau expression and phosphorylation in AD transgenic mouse models. Recently, T-006 has been proven to dramatically decrease the levels of total Amyloid β (Aβ) peptide and Glial Fibrillary Acidic Protein (GFAP) and suppress the expression of ionized calcium binding adaptor molecule-1 (Iba-1) in APP/PS1 mice.
