Inspired by the "Salvinia effect", a novel method for fabricating a magneto-responsive superhydrophobic surface coated with a cluster-distributed cilia array (CC-MRSS) was reported. This surface features a magnetically self-assembled nonuniform microcilia array and demonstrates exceptional microdroplet hydrophobicity, magnetic-responsive wettability, and corrosion resistance. The fabrication process involved mixing polydimethylsiloxane (PDMS) and carbonyl iron powders (CIPs), followed by dividing the mixture into two parts.

Tryptophan (Trp) is an essential amino acid obtained from human diet. It is involved not only in de novo biosynthesis of proteins but also in complex metabolic pathways. Redox transformation of tryptophan is under-explored in comparison with kynurenine, serotonin and indole pyruvate pathways.

Objectives: Small interfering RNA (siRNA) can silence disease-related genes through sequence-specific RNA interference (RNAi). Cationic lipid-based liposomes effectively deliver nucleic acids into the cytoplasm but often exhibit significant toxicity. This study aims to synthesize a novel ionizable lipid, Nε-laruoyl-lysine amide (LKA), from natural amino acids, constructed LKA-based liposomes, and perform physicochemical characterization and cell-based experiments to systematically evaluate the potential of these ionizable lipid-based liposomes for nucleic acid delivery.

Background: Triacylglycerol (TAG) plasma excursions after a high-fat meal are blunted after Roux-en-Y gastric bypass (RYGB), but underlying mechanisms are poorly understood. We studied TAG absorption and metabolism in 12 RYGB-operated individuals and 12 unoperated controls (CON) matched on sex, age, and BMI.
Methods: Participants followed a 7-day controlled diet and on day 4 underwent H-MR Spectroscopy of liver TAG and a high-fat liquid meal with oral and intravenous labeled stable isotope metabolites, subcutaneous abdominal fat biopsies, and indirect calorimetry.

Diffusion Magnetic Resonance Imaging (dMRI) sensitises the MRI signal to spin motion. This includes Brownian diffusion, but also flow across intricate networks of capillaries. This effect, the intra-voxel incoherent motion (IVIM), enables microvasculature characterisation with dMRI, through metrics such as the vascular signal fraction f or the vascular Apparent Diffusion Coefficient (ADC) D.
