Dietary Consumption of Type 2 Resistant Starch and d‐Fagomine Delays Progression of Metabolic Disturbances in Male Rats on High‐Fat Diet

Molecular Nutrition &Food Research, EarlyView.
This study compared the preventive effects of dietary resistant starch (RS2) from maize and d‐fagomine (FG) from buckwheat on cardiometabolic risk factors in high‐fat (HF) diet‐fed rats. Wistar‐Kyoto rats (n = 11–12/group) received STD, HF, HF + RS, or HF + FG diets for 10 weeks.

Assessing alternative strategies to control almond red leaf blotch through the reduction of Polystigma amygdalinum inoculum in leaf litter

Pest Management Science, EarlyView.
Cultural practices offer effective RLB disease management strategies. Urea application or removal of almond leaf litter reduces the primary inoculum of Polystigma amygdalinum. Abstract Background Red leaf blotch (RLB), caused by Polystigma amygdalinum, is a major foliar disease of almond trees in Mediterranean and Middle Eastern regions.
