Calculating the contribution of different binding modes to Quinacrine - DNA complex formation from polarized fluorescence data [PDF]

Biophysical Bulletin (Ukraine) 27(2) (2011) 31-39, 2013
Binding of acridine derivative quinacrine (QA) to chicken erythrocyte DNA was studied by methods of absorption and polarized fluorescent spectroscopy. Measurements were carried out in aqueous buffered solutions (pH 6.9) of different dye concentrations (QA concentration range from $10^{-6}$ till $10^{-4}$ M) and ionic strengths ($Na^{+}$ concentration ...

Thiol‐Modulation‐Induced Mesoporous Nanosheets with an Alloy/Intermetallic Heterophase for Efficient Electrochemical Ethylene Glycol‐Assisted Water Splitting

Advanced Functional Materials, EarlyView.
Sulfur‐capped mesoporous PtPbBi nanosheets (S‐PtPbBi MNSs) with an alloy/intermetallic compound heterophase and inhomogeneous tensile strain (≈3%) were synthesized by a thiol modification strategy, which exhibited excellent electrocatalytic performance for ethylene glycol oxidation reaction (EGOR).

Excitation transfer from Second to First resonance line of Potassium observed in hot atomic vapor [PDF]

arXiv, 2018
We present experimental investigation on the fluorescence profiles observed by excitation of the hyperfine transitions of the second resonance line of potassium with a wavelength of 404.4 nm in dependence on the atomic density. This leads to both direct decay of the excited level population to the ground state (violet fluorescence), and to cascade ...

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

Advanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

Advancing the Co‐Based Anode Catalysts Using Ionomers in Pure‐Water Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
The role of ionomers is investigated in advancing cobalt‐based oxygen evolution catalysts in pure‐water anion exchange membrane electrolysers. Using in situ electrochemical analysis, ex situ material characterization, and membrane potential sensing, it is observed surface reconstruction at high currents and mitigated it via ionomer coating, achieving ...

Five-dimensional single-shot fluorescence imaging using a polarized Fourier light-field microscope [PDF]

arXiv
Single-shot fluorescence imaging techniques have gained increasing interest in recent years due to their ability to rapidly capture complex biological data without the need for extensive scanning. In this letter, we introduce polarized Fourier light field microscopy (pFLFM), a novel fluorescence imaging technique that captures five-dimensional ...

TLR Agonist Nano Immune Therapy Clears Peritoneal and Systemic Ovarian Cancer

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Intraperitoneal administration of immunogenic Toll‐like receptor agonist‐modified mesoporous silica nanoparticles leads to rapid internalization by ascites myeloid cells with trafficking to fat‐associated lymphoid clusters. Activation of myeloid cells counters suppressive immune mechanisms associated with peritoneal metastasis, leading to regional and ...

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

Advanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential
