The current study aims to investigate the antioxidant activities of various extracts from defatted adlay seed meal (DASM) based on the oxygen radical absorbance capacity (ORAC) assay, peroxyl radical scavenging capacity (PSC) assay and cellular antioxidant activity (CAA) assay. Of all the fractions, the n-butanol fraction exhibited the highest antioxidant activity, followed by crude acetone extract and aqueous fractions. Of the three sub-fractions obtained by Sephadex LH-20 chromatography, sub-fraction 3 possessed the highest antioxidant activity and total phenolic content. There was a strong positive correlation between the total phenolic content and the antioxidant activity. Based on HPLC-DAD-ESI-MS/MS analysis, the most abundant phenolic acid in sub-fraction 3 of DASM was ferulic acid at 67.28 mg/g, whereas the predominant flavonoid was rutin at 41.11 mg/g. Of the major individual compounds in sub-fraction 3, p-coumaric acid exhibited the highest ORAC values, and quercetin exhibited the highest PSC values and CAA values.

Zinc finger proteins facilitate adaptation of a global insect pest to climate change.

Background: Global climate change significantly impacts ecosystems, particularly through temperature fluctuations that affect insect physiology and behavior. As poikilotherms, insect pests such as the globally devastating diamondback moth (DBM), Plutella xylostella, are especially vulnerable to rising temperatures and extreme heat events, necessitating effective adaptive mechanisms.
Results: Here we demonstrate the roles of zinc finger proteins (ZFPs) in mediating thermal adaptability in DBM.

Background/aim: Diabetic retinopathy (DR), a complication of diabetes, causes damage to retinal blood vessels and can lead to vision impairment. Persistent high blood glucose levels contribute to this damage, and despite ongoing research, effective treatment options for DR remain limited. Dimethyl sulfoxide (DMSO) has shown anti-inflammatory and antioxidant properties in both in vivo and in vitro studies; however, its potential as an anti-inflammatory agent in the context of DR has not yet been explored.

Background/aim: In a tongue-submandibular lymph node (SLN) metastasis model, the cystine/glutamate transporter solute carrier family 7, member 11 (Slc7a11), also known as xCT, was found to increase in lymphatic endothelial cells (LECs) within SLNs prior to melanoma cell metastasis. However, the precise mechanism by which xCT influences LECs remains unclear. This study aimed to explore the role of xCT in primary cultured LECs.

Background/aim: Breast cancer is mostly affected by estrogen, which promotes proliferation, tumorigenesis, and cancer progression. Estrogen sulfotransferase (SULT1E1) catalyzes sulfation to inactivate estrogens, whereas steroid sulfatase (STS) catalyzes estrogen sulfate hydrolysis to activate estrogens in breast cancer cells. Three major organosulfur compounds in garlic (Allium sativum L.

This research investigates the impact of microwave power, processing time, and solid-to-solvent ratio on protein recovery from foxtail millet (Setaria italica), using an artificial neural network (ANN) and genetic algorithm (GA). The extracted protein and subsequent hydrolysates were also evaluated for their techno-functional, structural, and digestibility properties. The ANN model, trained with the Levenberg-Marquardt algorithm and optimized by a GA, identified optimal extraction conditions (960 W, 66.
