Objectives: The aim of the present study was to evaluate the effect of açai pulp (Euterpe oleracea Martius) intake on the prevention of oxidative damage by measuring the activity of antioxidant enzymes and biomarkers of protein oxidation in women.
Methods: A nutritional intervention study was conducted with thirty-five healthy women who were asked to consume 200 g/d of açai pulp for 4 wk. Blood samples were collected, and blood pressure and anthropometric parameters were measured before and after the experimental period. Antioxidant enzymes, superoxide dismutase, catalase, glutathione, production of reactive oxygen species, and total antioxidant capacity were evaluated in polymorphonuclear cells. Serum concentration of protein carbonyl and sulfhydryl groups were also determined.
Results: The açai intake increased catalase activity, total antioxidant capacity, and reduced the production of reactive oxygen species. Furthermore, it reduced serum concentration of protein carbonyl and increased total serum sulfhydryl groups.
Conclusions: These results show the antioxidant benefit of dietary açai for the healthy women included in the present study, and may increase understanding of the beneficial health properties of this fruit.

Ethnopharmacological Relevance: Type 2 diabetes mellitus (T2DM) is a metabolic disease that can lead to complications affecting multiple organs, including the liver. Gegen Qinlian Decoction (GQD) has demonstrated considerable efficacy in the management of T2DM and its complications in accordance with the tenets of modern Chinese medicine. However, the molecular mechanism by which GQD alleviates diabetic liver injury is unclear.

Extreme conditions, such as cold and high humidity in northeast China's high-latitude maize region, can hinder crop yield and stability during the vegetative stage. However, there is a paucity of research examining the effects of simultaneous cold and high humidity stress on plant responses. In this study, we characterized the acclimation of JD558 (cold- and high humidity-sensitive hybrid) and JD441 (cold- and high humidity-tolerant hybrid) to stress at sowing caused by cold (4 °C), high humidity (25%), and their combined stress for five days, using physiological measurements and metabolomics during the stress treatments and recovery stages.

The ATP-binding cassette (ABC) gene family comprises some of the most critical transporter proteins in plants, playing vital roles in maintaining cellular homeostasis and adapting to environmental changes. While ABC transporters have been extensively characterized in various plant species, their profile in C. mollissima remains less understood.

Sclerotinia sclerotiorum is a severe disease that affects rapeseed (Brassica napus), resulting in significant yield losses. In previous study, we identified the candidate GLUTATHIONE S-TRANSFERASE (GST) gene, BnGSTU12, associated with sclerotiorum stem resistance and the expression levels of BnGSTU12 in resistant lines were higher than that in susceptible lines. We analyzed the function of the BnGSTU12 during S.

The high global production combined with low recycling rates of polystyrene (PS) and low-density polyethylene (LDPE) contributes to the abundance of these commonly used plastics in soil, including as microplastics (MPs). However, the combined effects of MPs and heavy metals, such as arsenic (As) on earthworms are poorly understood. Here, we show that neither PS nor LDPE altered the effects of As on the survival, growth, and reproduction of the earthworm Eisenia fetida.
