Alkylresorcinols (ARs), a homolog series of phenolipids naturally occurring in many by-products, can meet the high demand of the food industry for natural antioxidants. In this study, ARs (C17-C25) were isolated from wheat bran, and their antioxidant activity was tested in oil-in-water emulsions at pH 3.5 and pH 7.

- Secondary metabolites are compounds that help organisms defend against others or attract mates, and their production is influenced by evolutionary factors.
- This study focused on the ecotoxicological effects of extracts from three marine sponges and two benthic diatoms on marine organisms, specifically the Mediterranean purple sea urchin and other diatoms.
- Results indicated that while unfertilized eggs showed some protection from harmful sponge compounds, treatments with sponge extracts had significant negative effects post-fertilization, and diatom extracts led to increased malformations in both pre- and post-fertilization stages.
Due to their antioxidant activity, alkylresorcinols (ARs) extracted from by-products could represent promising natural and innovative antioxidants for the food industry. This study tested the ability of ARs isolated from wheat bran to increase the shelf-life of minced-meat models stored at 4 °C for 9 days. Fifteen alk(en)ylresorcinols (C17-C25) were recognized by GC/MS, showing good radical-scavenging (200.

An every-2-weeks schedule (500 mg/m Q2W) was approved recently by several health authorities. Being synchronized with chemotherapy, Q2W administration should improve patients' convenience and healthcare resource utilization.

In the present work, we analyzed the biotechnological potential of the alien species () de Weerdt, de Kluijver & Gomez, 1999, previously collected in the Mediterranean Sea (Faro Lake, Sicily). The bioactivity and chemical content of this species has never been investigated, and information in the literature on its Caribbean counterpart is scarce.
