Study and application of the profile-attenuation-based standardized soil moisture index

Cold-region spring crops are highly sensitive to water stress during the seedling stage, making spring agricultural drought a major constraint on crop productivity in semi-arid regions. Conventional drought monitoring often relies on the Standardized Soil Moisture Index (SSMI), w...

Evaluation of the structure and function of whey protein concentrate combined with folic acid and l ‐ascorbyl 6‐palmitate

Abstract BACKGROUND Whey protein concentrate 80 (WPC80) represents a highly promising carrier for bioactive compounds; however, the structural and functional consequences resulting from its noncovalent interactions with folic acid (FA) and l ‐ascorbic acid 6‐palmitate (LAP) remai...

Multi-Algorithm Hierarchical Minimum Data Sets for Soil Quality Assessment in the Black Soil Region of Northeast China: A Case Study in Keshan County

The Northeast black soil region is a major grain-producing area in China, where county-scale assessment of topsoil quality is essential for soil conservation and provides a potential indicator framework for regional soil quality monitoring. In this study, 500 composite cultivated...

Regulation of Egg Quality by Methionine Selenium: Physicochemical and Structural Characteristics of EggShell, Egg Yolk, and Egg White

Selenium is an essential trace element in the body, and supplementing it in production can improve egg quality. Sixty healthy 48-week-old Hy-Line Brown laying hens were randomly assigned to two groups. In this study, the effects of dietary selenomethionine (SeMet) supplementation...

Biological and metabolism responses of earthworm (Eisenia fetida) exposed to metribuzin

Metribuzin, a widely used triazine herbicide, has been extensively studied for its toxic effects on aquatic organisms, but its impact on soil organisms, particularly earthworms, remains insufficiently understood. This study investigates the ecological toxicity of metribuzin on Ei...

Lycopene AttenuatesDEHP-Induced Cerebral Injury bySuppressing cGAS-STING-Mediated Microglial Activation

Abstract Di(2-ethylhexyl) phthalate (DEHP) is a widespread environmental pollutant with neurotoxicity, while lycopene (LYC) is a neuroprotective dietary carotenoid. This study investigated whether LYC alleviates DEHP-induced brain injury by regulating microglial activation and cG...

Ketogenic diet induces cardiac changes via the OHB-Ffar3-Hopx/ACTC1 regulatory pathway in growing mice

The ketogenic diet (KD), a high-fat, low-carbohydrate dietary regimen widely used for drug-resistant epilepsy and weight management, has been increasingly applied in adolescents. However, its long-term effects on juvenile cardiac development and functional homeostasis remain poor...

Effects of Fermented Palm Kernel Meal on Lactation Performance, Rumen Fermentation, Rumen Microbiota, and Rumen Metabolomic Profiles in Holstein Dairy Cows

This study evaluated the impact of fermented palm kernel meal (FPKM) on the lactation performance, blood biochemical indices, rumen microbiota, and metabolic functions of Holstein dairy cows, aiming to enhance the nutritional value of palm kernel meal (PKM) through solid-state fe...
