Chemical signature of colorectal cancer: case-control study for profiling the breath print. [PDF]

BJS Open, 2020
Available screening methods for colorectal cancer have poor reliability and low patient compliance. Cancer cells produce altered metabolites, which are transported in the bloodstream and released in the alveoli; these volatile organic compounds (VOCs) can be detected in exhaled breath.

Raphanus sativus functional potential: Impact of the analytical extraction technique on the bioaccessibility interpretation

Food Safety and Health, Volume 1, Issue 1, Page 93-101, July 2023., 2023
Radishes are an important source of bioactive isothiocyanates. We studied the bioaccessibility of isothiocyanates and I3C of radishes. Analytical implications of human intake were considered. Aqueous‐hydrolysis/DLLME showed good suitability for the bioaccessibility assessment.

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

Journal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...

Folin‐Ciocalteu Reaction Alternatives for Higher Polyphenol Quantitation in Colombian Passion Fruits

International Journal of Food Science, Volume 2021, Issue 1, 2021., 2021
Passiflora edulis Flavicarpa, Passiflora edulis Sims, and Passiflora ligularis Juss are Colombian fruits (passion fruits) of important exportation value. They act efficiently as antioxidants, antifungal, and antimicrobial compounds due to their high polyphenol content. Polyphenols can be quantified by the Folin‐Ciocalteu (F‐C) reaction.

Production and Characterization of Polyhydroxyalkanoates and Native Microorganisms Synthesized from Fatty Waste

International Journal of Polymer Science, Volume 2016, Issue 1, 2016., 2016
Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible plastics. They are synthesized by a wide variety of microorganisms (i.e., fungi and bacteria) and some organisms such as plants, which share characteristics with petrochemical‐based plastics.

Liposomal Formulation of Turmerone‐Rich Hexane Fractions from Curcuma longa Enhances Their Antileishmanial Activity

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
Promastigote forms of Leishmania amazonensis were treated with different concentrations of two fractions of Curcuma longa cortex rich in turmerones and their respective liposomal formulations in order to evaluate growth inhibition and the minimal inhibitory concentration (MIC).

Photoprotective effect of topical treatment with Lopezia racemosa extract against deleterious UVB irradiation effects in the skin of hairless mice

Photochemistry and Photobiology, Volume 100, Issue 5, Page 1489-1506, September/October 2024.
Lopezia racemosa is one of the most important weeds of Mexican origin. The methanolic extract of this plant (MELR) is mainly composed of 5 glycosides derived from quercetin. MELR has ability to scavenge radicals such as DPPH and ABTS. In addition, it has absorption in the UVA region.
