Formation and biological effects of deoxyribonucleic acid (DNA) adducts from endogenous and exogenous aldehydes.

Magneto-responsive hydrogels are important platforms for biomedical applications, such as drug delivery, tissue engineering and cancer therapy, and for environmental applications.

This review celebrates the centenary of chemical investigations on Aspergillus niger. Structurally diverse secondary metabolites produced by this fungus, besides its potential on selective biotransformation of terpenes, are presented.

Three new naphthoquinones, including one with cytotoxic activity, were isolated from the tubers of Sinningia reitzii.

Synthesis of Au nanoparticles with poly(3,4-ethylenedioxythiophene)-poly(D,L-lactic acid) (PEDOT-PDLLA) composite was demonstrated, easily immobilizing films with conductive and biocompatible properties used as biointerface.

Simple and fast electrode for determination of bisphenol A in plastic samples using a carbon paste electrode modified with ionic liquid.

Fingerprinting provides an indication of the changes in regulatory metabolites in leaves provoked by water-deficit stress by means of an integrated chemometric approach. Fermentation, nutritional deficiencies, senescence and abscission were prevalent in unirrigated plants.

IrRh surfaces are selective to CO₂ production (from ethanol), while IrRhSn promotes the occurrence of a dual oxidation pathway that also generates acetic acid.

A typical direct assay for phosphoenolpyruvate carboxykinase by liquid chromatography-tandem mass spectrometry (LC-MS/MS) with phosphoenolpyruvate detection.

Imidazole reacts differently with various organophosphates, including an unusual N-alkylation. This promiscuity boosts the versatility of imidazoles.

The antidepressant tianeptine and its esters induce the fluorescence quenching of BSA due to the proximity to Trp134 and Trp213 amino acids as revealed by molecular modeling.

The analysis of plasma samples from pregnant women with preeclampsia and healthy pregnancies by liquid chromatography coupled to high-resolution mass spectrometry shows that there are significant differences between samples in the levels of some free amino acids.

The one-pot synthesis of 4-organylselanylpyrazoles from 1,3-diketones, hydrazines and diaryl diselenides using Oxone^® was developed.

Linear pohlianin B and linear ribifolin are peptide analogues originally designed from natural orbitides. The promising results demonstrated that they have the potential to induce neonatal human foreskin fibroblast migration and collagen deposition.

Gold catalysts activated by Lewis bases are highly selective for the hydrogenation of bio-derived aldehydes into alcohols, such as 2,5-dihydroxymethylfuran (DHMF).

Dye degradation mediated by titanium free catalyst occurs mostly in homogeneous phase while with molar ratio Ti/Fe = 0.4 heterogeneous process is predominant at pH 5.6.

The image is a representation of porous of BEA zeolite after reaction with ammonium hexafluorosilicate (AHFS), showing the formation of bigger extra-framework aluminum (EFAL) species without washing, and the respective washing procedure, as well as product selectivity depending on weight hourly space velocity (WHSV).

An eco-friendly method was developed for chlorine and fluorine determination in eye-pencil, combining microwave-induced combustion (MIC) for sample preparation with ion chromatography (IC) for the element determination.

Phase transitions, thermal stability, kinetics, and activation parameters of degradation of imidazolium-based ionic liquids were evaluated.

For Ti substrate the electron transfer rate is very fast, which should be responsible for the high activity of the catalyst. Hydrogen evolution reaction is more favorable on Ti/MoS₂ than fluorine-tin doped oxide (FTO)/MoS₂ decreasing the overpotential and Tafel slope.

The effect of water models, long-range electrostatics treatment and charge cutoff schemes on atomistic molecular dynamics (MD) simulations of bacterial outer membranes with the GROMOS force field.

The interaction between lipase from Candida sp. and gold nanoparticles was fully investigated at different length scales revealing important information about the nano-bio interface of this bio-conjugate, as seen by transmission electron microscopy (TEM) images.
