Silybum marianum Extract: A Highly Effective Natural Alternative to Retinoids to Prevent Skin Aging Without Side Effects.

Background: Vitamin A, or retinol, is one of the most effective antiaging molecules, but it presents issues with photo-sensitivity and irritation. Alternatives are emerging, but have so far been less effective.

Objective: Here, we present a Silibum marianum extract (SME) as a retinol-like ingredient providing both safety and efficacy.

Epigallocatechin Gallate Enzymatic Alpha Glucosylation Potentiates Its Skin-Lightening Activity-Involvement of Skin Microbiota.

(1) Background: Ultraviolet radiation takes part in photoaging and pigmentation disorders on skin. Epigallocatechin gallate (EGCG) is a well-known brightening and photoprotective compound but it faces limitations in terms of stability and solubility. (2) Methods: A more stable and water-soluble glucoside called EGCG-G1 was obtained by enzymatic glucosylation of EGCG.

Assessing the spread of sulfachloropyridazine in poultry environment and its impact on Escherichia coli resistance.

Sulfachloropyridazine (SCP) is an antimicrobial (AM) commonly used in the poultry industry. This drug is excreted as the original compound, which may accumulate in litter. This work was done to assess whether SCP residues from droppings of broiler chickens that were treated with therapeutic doses of this drug spread into the production environment and to determine if these events were associated with the selection of resistant bacteria.

Simultaneous analysis of antimicrobial residues and contaminants in poultry droppings by HPLC-MS/MS: a tool for environmental and food safety monitoring.

Animal waste is a potential pollution hazard as it can harbour contaminants, such as antimicrobial residues, mycotoxins, and pesticides, becoming a risk to the public, animal, and environmental health. To assess this risk, 15 experimental broiler chickens orally received contaminants to evaluate excretion levels. An analytical method was previously developed to detect 18 substances in poultry droppings using high-performance liquid chromatography coupled to a tandem mass spectrometer (HPLC-MS/MS).
