Study of Grape Polyphenols by Liquid Chromatography‐High‐Resolution Mass Spectrometry (UHPLC/QTOF) and Suspect Screening Analysis

Journal of Analytical Methods in Chemistry, Volume 2015, Issue 1, 2015., 2015
Suspect screening analysis is a targeted metabolomics method in which the identification of compounds relies on specific available information, such as their molecular formula and isotopic pattern. This method, coupled to liquid chromatography‐high‐resolution mass spectrometry, is effective in the study of grape metabolomics, in particular for ...

An Antioxidant Dietary Supplement Improves Brain‐Derived Neurotrophic Factor Levels in Serum of Aged Dogs: Preliminary Results

Journal of Veterinary Medicine, Volume 2015, Issue 1, 2015., 2015
Biological aging is characterized by a progressive accumulation of oxidative damage and decreased endogenous antioxidant defense mechanisms. The production of oxidants by normal metabolism damages proteins, lipids, and nucleotides, which may contribute to cognitive impairment.

Fungal associates of the tree-killing bark beetle, Ips typographus, vary in virulence, ability to degrade conifer phenolics and influence bark beetle tunneling behavior [PDF]

, 2018
The bark beetle Ips typographus carries numerous fungi that could be assisting the beetle in colonizing live Norway spruce (Picea abies) trees. Phenolic defenses in spruce phloem are degraded by the beetle's major tree-killing fungus Endoconidiophora ...

Multi‐Omics Analysis of Ileal Mucosa and Mesentery Before and After Ileocecal Resection in Crohn's Disease

United European Gastroenterology Journal, Volume 13, Issue 7, Page 1239-1252, September 2025.
ABSTRACT Crohn's disease (CD), a type of inflammatory bowel disease (IBD), is a chronic disorder involving any part of the gastrointestinal tract. Ileocecal resection may serve as a more effective treatment option for early CD. However, the potential relationship and mechanisms between the ileocecum and remission induction of CD are still elusive.

Metabolic Engineering of Yeast and Plants for the Production of the Biologically Active Hydroxystilbene, Resveratrol

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Resveratrol, a stilbenic compound deriving from the phenyalanine/polymalonate route, being stilbene synthase the last and key enzyme of this pathway, recently has become the focus of a number of studies in medicine and plant physiology. Increased demand for this molecule for nutraceutical, cosmetic and possibly pharmaceutic uses, makes its production a

Antitermite Activities of C. decidua Extracts and Pure Compounds against Indian White Termite Odontotermes obesus (Isoptera: Odontotermitidae)

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
In the present investigation, we have tested antitermite responses of Capparis decidua stem, root, flower, and fruit extracts and pure compounds to Odontotermes obesus in various bioassays. Crude stem extract has shown very high susceptibility and very low LD50 values, that is, 14.171 μg/mg in worker termites.
