Anti-Obesity Effects Evaluation of a Blackcurrant Leaf Standardized Hydro-Alcoholic Extract in Wistar Rat Subjected to a High-Fat Diet.

Blackcurrant (BC) extract was reported to exert anti-obesity effects. However, it is unknown whether BC extract with a composition close to the totum differentially affects obesity when compared to one of its active compounds. We evaluated the anti-obesity effects of a BC standardized hydro-alcoholic leaf extract (BC-HLE) in an HFD-induced obesity rat model and compared them with quercetin (QUE).

Amitraz Resistance in French Mite Populations-More Complex Than a Single-Nucleotide Polymorphism.

Resistance against amitraz in mite populations has become a subject of interest in recent years due to the increasing reports of the reduced field efficacy of amitraz treatments, especially from some beekeepers in France and the United States. The loss of amitraz as a reliable tool to effectively reduce mite infestation in the field could severely worsen the position of beekeepers in the fight to keep infestation rates in their colonies at low levels. In this publication, we present data from French apiaries, collected in the years 2020 and 2021.
