Two new coumarin-based “turn-off” fluorescent probes, (E)-3-((3,4-dihydroxybenzylidene)amino)-7-hydroxy-2H-chromen-2-one (BS1) and (E)-3-((2,4-dihydroxybenzylidene)amino)-7-hydroxy-2H-chromen-2-one (BS2), were synthesized their detection of copper(II) iron(III) ions was studied. Results show that both compounds are highly selective for Cu2+ Fe3+ over other metal ions. However, BS2 is detected directly, while BS1 involves a hydrolysis reaction to regenerate 3-amino-7-hydroxycoumarin (3)...

mRNA lipid nanoparticle (LNP) technology presents enormous opportunities to prevent and treat various diseases. Here, we developed a novel series of LNPs containing ionizable amino-lipids showing remarkable array tunable pH-sensitive lyotropic liquid crystalline mesophases including the inverse bicontinuous cubic hexagonal phases characterized by high-throughput synchrotron radiation X-ray scattering. Furthermore, with an interest in developing therapeutics for lung macrophage targeting,...

Abstract Macrophages are unique immune cells attracting growing attention as a potential candidate for cell‐based therapy infectious diseases and cancer. Strategies that can reprogramme or gene‐edit macrophages hold across spectrum of acute chronic conditions. Herein, lipid nanoparticles (LNPs) developed containing the ionizable SM‐102, helper monoolein which is known self‐assembly in aqueous solutions into inverse cubic lyotropic liquid crystalline mesophase, cholesterol an mRNA...

Aged and adult populations have differences in the structural, biological, healing properties of skin. Comparative studies under influence retinoids both these are very important and, to best our knowledge, not been performed date. The purpose this study was compare activities topical tretinoin aged animal models wound by secondary intention. Male rats (24 months old, n = 7) (6 8) were used. assigned following groups according dates on which samples excised (day 14 or 21 after model...

Deep eutectic solvents (DES) formed using choline chloride (ChCl), p-toluenesulfonic acid (pTSA) of stoichiometry ChCl: pTSA (1:1) and (1:2), its ternary mixtures with phosphoric (PA) 85% as an additive (ChCl: pTSA: PA) were evaluated for cellulose nanocrystal (CNC) isolation. Initially, the hydrolytic efficiency to produce CNC each DES was compared before after adding by Hammett acidity parameters Gutmann acceptor number. Moreover, different molar ratios reaction time studied at 80°C...

Fourth generation polyamidoamine dendrimer (PAMAM, G4) modified with fluorescein units (F) at the periphery and Pt nanoparticles stabilized by L-ascorbate were prepared. These dendrimers hydrophobic used to achieve self-assembling structures, giving rise formation of nanoaggregates in water. The photoactive mainly as photosensitizer process catalytic photoreduction water propitiated light. Complementarily, Pt-ascorbate acted active sites generate H2. Importantly, study functional, optical,...

Both chemotherapy (CT) and endocrine therapy + abemaciclib (ET/ABE) are recommended for high-risk HR+/HER2 early breast cancer (EBC). It is unclear if 12 months (mo.) of ET/ABE could replace CT. We investigate this by comparing their efficacy in neoadyuvant (NAT) setting. CARABELA (NCT04293393) a phase II, randomized, open-label, study mo.
