Targeting the ARRDC3–DRP1 Axis via hUMSC‐Derived Exosomal CRYAB for Neuroprotection in Cerebral Ischemia/Reperfusion Injury

Advanced Healthcare Materials, EarlyView.
Intranasally administered hUMSC‐derived exosomes modulate the CRYAB–ARRDC3–Drp1 axis, alleviating mitochondrial dysfunction and ferroptosis, enhancing neuronal survival, reducing oxidative stress, and promoting functional recovery in ischemia‐reperfusion injury, offering a promising therapeutic strategy for ischemic stroke.

Redefining Therapies for Drug‐Resistant Tuberculosis: Synergistic Effects of Antimicrobial Peptides, Nanotechnology, and Computational Design

Advanced Healthcare Materials, EarlyView.
Antimicrobial peptide (AMP)‐loaded nanocarriers provide a multifunctional strategy to combat drug‐resistant Mycobacterium tuberculosis. By enhancing intracellular delivery, bypassing efflux pumps, and disrupting bacterial membranes, this platform restores phagolysosome fusion and macrophage function.

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

Advanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

Simvastatin Restores Uteroplacental Hemodynamics and Trophoblast Function in Obstetric Antiphospholipid Syndrome in a Placenta‐on‐a‐Chip Model

Advanced Healthcare Materials, EarlyView.
Simvastatin mitigates placental hypoperfusion in OAPS by ameliorating abnormal uteromaternal hemodynamics and enhancing trophoblast invasion via optimized endothelial cell interactions under pathological shear stress, as evidenced by results from a placenta‐on‐a‐chip platform.

Phosphonate Lipid Tubules II

Journal of the American Chemical Society, 2002
We describe a new chiral tubule-forming lipid in which the C-O-P phosphoryl linkage of the archetypal tubule-forming molecule, 1,2-bis(10,12-tricosadiynoyl)-sn-glycero-3-phosphocholine, "DC(8,9)PC", is replaced by a C-P linkage. Tubule formation with this phosphonate analogue proceeds under the same mild conditions as with DC(8,9)PC and produces ...

Lipids in photosystem II: Multifunctional cofactors

Journal of Photochemistry and Photobiology B: Biology, 2011
To maintain its functionality, photosystem II (PSII) employs several types of auxiliary molecules (cofactors). As shown for PSII from Thermosynechococcus elongatus, lipids previously thought to play mostly the role of a hydrophobic matrix for embedding the membrane proteins, must be considered as a new, multifunctional type of cofactors, playing a ...

Lipid components of human ferroxidase-II

Biochemical and Biophysical Research Communications, 1973
Abstract Cholesterol and phospholipids remain tightly associated with the ferroxidase-II protein from human serum following extensive purification. Purified ferroxidase-II preparations show a consistent ratio of protein, phospholipid, and cholesterol. Thin-layer chromatographic analyses indicate that phosphatidyl choline accounts for 70% of the bound

Synthesis of lipid II phosphonate analogues

Carbohydrate Research, 2011
Simple analogues of lipid II were synthesized from 3,4,6-tri-O-acetyl-2-acetamido-2-deoxy-1-thio-β-D-glucopyranose using conjugate addition onto ethylidene bisphosphonate and subsequent Wadsworth-Horner-Emmons reaction with long chain aliphatic aldehydes.

Lipids of protozoa. II. Lipids ofParamecium aurelia andParamecium caudatum

Chemistry of Natural Compounds, 1990
The phospholipid composition of two species of infusorians (Ciliophora) has been investigated. It has been shown that the alkyl form is present in the phosphatidylethanolamines and their phosphonic analogs, and in the phosphatidylcholine, phosphatidylserine, and phosphatidylinositol. The main fatty acid in the total lipid extracts was arachidonic.
