A peptide gemini surfactant, 12-G(NH2)LG(NH2)-12, has been constructed with two dodecyl chains separately attached to the two terminals of a glutamic acid-lysine-glutamic acid peptide and the aggregation behavior of the surfactant was studied in aqueous solution. The 12-G(NH2)LG(NH2)-12 molecules form fiber-like precipitates around pH 7.0, and the precipitation range is widened on increasing th...

A novel type of pH-responsive biodegradable copolymer was developed based on methyloxy-poly(ethylene glycol)-block-poly[dopamine-2-(dibutylamino) ethylamine-l-glutamate] (mPEG-b-P(DPA-DE)LG) and applied to act as an intelligent nanocarrier system for magnetic resonance imaging (MRI). The mPEG-b-P(DPA-DE)LG copolymer was synthesized by a typical ring opening polymerization of N-carboxyanhydrides...

Herein we report that mixed zirconium-cerium-MOFs with amino-functionalized linkers (2-amino-1,4-benzenedicarboxylate, BDC-NH2, and 4-aminonaphthalene-2,6-dicarboxylate, NDC-NH2) act as effective non-noble-metal-based heterogeneous catalysts, for both the aerobic photooxidation of benzylic alcohols direct microwaves activation N-alkylation amines alcohols. The catalytic performance has been stu...

UNLABELLED The glucagon-like peptide-1 (GLP-1) receptors are important biomarkers for imaging pancreatic β-cell mass and detection of benign insulinomas. Using GLP-1 receptor antagonists, we aimed to eliminate the insulin-related side effects reported for all GLP-1 receptor agonists. Additionally, using a nonresidualizing tracer, (125)I-Bolton-Hunter-Exendin(9-39)NH2 ((125)I-BH-Ex(9-39)NH2), we...

The treatment of Sb (III) wastewater produced from mining activities is uniquely challenging and has therefore garnered increasing attention. Here, an amino-modified zirconium-based metal-organic framework material (UiO-66-NH2) its composites were loaded onto graphene oxide (GO@UiO-66-NH2) via the hydrothermal method, after which these materials used to adsorb in mine wastewater. effects adsorp...

We evaluated the systemic hemodynamic effects induced by nociceptin (NC) and NC-related peptides, including the NC receptor antagonist [Phe1psi(CH2-NH)Gly2]NC(1-13)NH2 ([F/G]NC(1-13)NH2) in unanesthetized normotensive Swiss Morini mice. Bolus intravenous injection of NC decreased mean blood pressure and heart rate. The hypotensive response to 10 nmol/kg NC lasted <10 minutes, whereas a more pro...

Nickel nanoparticles (NiNPs) immobilized on halloysite-based supports were straightforwardly synthesized and fully characterized by different techniques with the purpose of evaluating catalytic performance these as-prepared composite materials as catalysts in hydrogenation reactions. Thus, halloysite bearing amino (HAL-NH2) ammonium (HAL-NEt3) groups led to less active comparison unfunctionaliz...
