The inclusion interaction of water-soluble p-(N,N-dimethylaminomethyl)-calix[8]arene with diphenylamine-4-sulfonic acid sodium salt was investigated by fluorimetric method. When diphenylamine-4-sulfonic acid sodium salt was added into the p-(N,N-dimethylaminomethyl)-calix[8]arene solution, the
We study the elimination of two viscoelastic substances from the vitreous cavity: the Hydroxypropyl Methylcellulose and the Sodium Hyaluronate that are potentially vitreous substitutes. We performed gas-vitrectomy in 116 eyes of 58 rabbits. Three days after surgery we performed gas-viscoelastic
Diphenylamine metabolism and ethylene action were evaluated as factors influencing the development of 'Braeburn' apple internal browning and cavitation during cold storage. Apples treated with the antioxidant diphenylamine (DPA) and/or the ethylene action inhibitor 1-methylcyclopropene (1-MCP) were
The influence of molecular weight on the elimination kinetics of the potential vitreous substitute hydroxypropyl methylcellulose (HPMC) was studied using solutions of equal viscosity (15,000 cps) of HPMC of molecular weight 86,000 daltons (HPMC 86,000) and HPMC of molecular weight 120,000 daltons
This paper describes the first reversible, heat-set organogel based on the supramolecular interactions of beta-cyclodextrin (beta-CD). The gel was prepared by interaction of diphenylamine (DPA) with beta-CD and lithium chloride in N,N-dimethylformamide (DMF). In this gel system, DPA could be gelated
The small-molecule trans-3,4-disubstituted pyrrolidine 6 was identified from in silico three-dimensional (3D) pharmacophore searches based on known X-ray structures of renin-inhibitor complexes and demonstrated to be a weakly active inhibitor of the human enzyme. The unexpected binding mode of the
Fluorescence (FL) imaging in the second near-infrared window (NIR-II, 1000-1700 nm) has emerged as a promising bioim-aging modality that enables noninvasive visualization of deep-tissue with an unprecedented resolution. However, there is a paucity of studies on high-quality responsive NIR-II FL
