Factors affecting distribution and ecological risk assessment of volatile organic compounds (VOCs) in groundwater of the Huazhou district in northwestern China.

Volatile organic compounds (VOCs) pollution in groundwater is a significant global concern. In this study, 26 groundwater samples were collected from the unconfined aquifers in Huazhou District, northwestern China, to assess their distribution characteristics, influencing factors, and ecological risks across various geomorphological settings. The findings revealed 35 VOCs in collected groundwater samples, with aromatic hydrocarbons having the highest detection rate (100%), and the VOCs distribution exhibited significant spatial variations, with the highest VOCs concentration near a chemical plant on the inclined pluvial plain.

Distribution characteristics, source identification and health risk assessment of trace metals in the coastal groundwater of Taizhou City, China.

This study was carried out to evaluate and analyze the fluctuations in groundwater for certain trace metals (Fe, Mn, Cu, Zn, Al, Cd, Cr, Pb, As, and Se) in Taizhou City over three years (2020-2022), evaluate the potential human health risks due to the consumption of groundwater. To quantify the spatiotemporal changes in groundwater trace metals, the heavy metal pollution index (HPI) and heavy metal evaluation index (HEI) were utilized. Furthermore, multivariate statistical methods were utilized to distinguish the sources of trace elements.

Effects of Octenyl-Succinylated Chitosan-Whey Protein Isolated on Emulsion Properties, Astaxanthin Solubility, Stability, and Bioaccessibility.

The synthesis of octenyl-succinylated chitosan with different degrees of substitution resulting from chemical modification of chitosan and controlled addition of octenyl succinic acid was investigated. The modified products were characterized using H NMR, FTIR, and XRD, and the degree of substitution was also determined. The properties of the modified chitosan oligosaccharide in solution were evaluated by surface tension and dye solubilization, finding that the molecules self-assembled when they are above the critical aggregation concentration.

Non-covalent binding of whey protein isolate after ultrasound pretreatment to epigallocatechin gallate: Effects on immune response and gut microbiota in BALB/c mice.

Cow's milk is one of the "big eight" most common allergenic foods, and β-lactoglobulin and α-Lactalbumin in whey protein are two major allergens of cow's milk protein. An effective strategy for reducing the allergenicity of whey protein is needed. In the present study, protein-EGCG complexes were obtained through non-covalent interactions between untreated or sonicated whey protein isolate (WPI) and epigallocatechin gallate (EGCG), and the allergenicity of complexes was assessed in vivo.

BL-10 with Antioxidant Capacity Ameliorates Lipopolysaccharide-Induced Acute Liver Injury in Mice by the Nuclear Factor-κB Pathway.

is frequently utilized and has broad prospects for preventing liver injury. The current research assessed the antioxidant capacity of BL-10 and probed its mechanism for ameliorating lipopolysaccharide (LPS)-induced acute liver injury (ALI). BL-10-encoded 15 antioxidant genes showed strong reducing power activity and scavenging activity of DPPH, hydroxyl radicals, and superoxide anions.

The bioavailability of soy isoflavones in vitro and their effects on gut microbiota in the simulator of the human intestinal microbial ecosystem.

Since soy isoflavones have many potentially beneficial properties, they have received increasing attention. However, there are few studies on their bioavailability and effects on gut microbiota. In this experiment, the simulator of the human intestinal microbial ecosystem (SHIME) was used to study the bioavailability of soy isoflavones and their effects on gut microbiota.

Conformational changes and functional properties of whey protein isolate-polyphenol complexes formed by non-covalent interaction.

The present study was conducted to evaluate the non-ovalent modifications of whey protein isolate (WPI) with gallic acid (GA), chlorogenic acid (CA) and epigallocatechin gallate (EGCG). The structural and functional properties of WPI before and after binding with GA, CA and EGCG were investigated. Results showed that free sulfhydryl groups and surface hydrophobicity significantly decreased in WPI after binding with phenolic compounds.

KLDS1.0318 Ameliorates Impaired Intestinal Immunity and Metabolic Disorders in Cyclophosphamide-Treated Mice.

Cyclophosphamide (CTX), a clinically important antineoplastic drug, also leads to some side effects such as nausea, vomiting and diarrhea in the consumer. In this study, () KLDS1.0318 preserved in our laboratory was orally administered to CTX-treated mice to explore its potential effects to attenuate the toxic effects of CTX-induced by modulating intestinal immune response, promoting intestinal integrity and improving metabolic profile.

Immunomodulatory activity of KLDS1.0318 in cyclophosphamide-treated mice.

Background: Probiotics in fermented foods have attracted considerable attention lately as treatment options for immune diseases, the incidence of which has been increasing throughout the world.

Objective: The objective of the present study was to investigate the immunomodulatory activity of () KLDS1.0318 in cyclophosphamide-treated mice.

Short communication: Genomic and phenotypic analyses of exopolysaccharides produced by Streptococcus thermophilus KLDS SM.

Streptococcus thermophilus plays important roles in the dairy industry. Streptococcus thermophilus KLDS SM could produce a high amount of exopolysaccharides (EPS). To understand the possible link between the genotype and the phenotype regarding EPS, the complete genome of S.

Complete Genome Sequence of KLDS 3.1003, A Strain with High Antimicrobial Potential against Foodborne and Vaginal Pathogens.

Lactic acid bacteria play increasingly important roles in the food industry. KLDS 3.1003 strain was isolated from traditional yogurt in Inner Mongolia, China.
