A previously unreported xylated glycosaminoglycan with a β‐D‐Xylop(1 → 3)‐(⋯ → 4)‐GlcpA(1 → 3)‐GlcpNAc(1 → ⋯) framework was isolated to homogeneity from marine buccinid gastropod Babylonia spirata, and was found to possess potential antioxidant and 5‐lipoxygenase attenuation activities. The isolated metabolite might be anticipated as potential naturally‐derived bioactive constituent in functional food and pharmaceutical applications.

In this study, an effective speed‐regulated directly suspended droplet microextraction method was developed to condense pesticide residues from teas through dispersive solid‐phase extraction prior to analysis by GC–MS/MS. The extractant was intentionally dispersed into the sample solution in the form of globules through high‐speed agitation. This procedure increases the contact area between the binary phases and shortens the distribution equilibrium time.

Cryptosporidiosis is a significant cause of gastroenteritis in both humans and livestock in developing countries. The only FDA-approved drug available against the same is nitazoxanide, with questionable efficacy in malnourished children and immunocompromised patients.

Polychlorinated biphenyls (PCBs), which cause environmental pollution, are found in animal-based fatty foods. Due to their long half-life and lipophilic properties, they can accumulate in the fat tissues of cattle. The study was conducted to compare the PCB levels (PCB28, 52, 101, 118, 138, 153, and 180) in the different fat tissues (muscle, liver, kidney, spinal cord, lung, back fat, perihepatic fat, and perirenal fat) of cattle by age and gender.

BACKGROUND The presence of acrylamide in food has attracted wide attention and has raised concerns due to its potential toxic and carcinogenic effects. The phenolic compounds in buckwheat display strong antioxidant activity, which may affect the acrylamide levels. The aims of this study were to evaluate the effect of buckwheat extracts on acrylamide formation and the quality of the bread, and to investigate possible inhibitory mechanisms.

Increasingly variable hydrologic regimes combined with more frequent and intense extreme events are challenging water systems management worldwide. These trends emphasize the need of accurate medium‐ to long‐term predictions to timely prompt anticipatory operations.

Acrylamide is a toxic compound and a thermal marker of food, deriving from Maillard reaction. A recent European Regulation established mitigation measures and benchmark levels for its reduction in many products encouraging the use of colourimetric scales providing a statistical correlation between colour intensity and acrylamide content.

In order to trace the source of Pb pollution in wheat, the contribution ratio of soil and atmospheric fallout source was quantified based on stable isotope ratios. Results showed that the average Pb content of soil was significantly lower than that of fallout, and Pb in the fallout had a higher weak acid fraction than soil. Pb in wheat had a distinct distribution in its tissues and the content of Pb in wheat roots was significantly higher than it in shoots.

Climate change is expected to alter hydrological cycles on global and regional scales, impacting groundwater and surface water inputs to stream habitats. In the midwestern United States, the volume and frequency of inputs are expected to become increasingly variable. This region has a high incidence of agriculture, creating enormous potential for transport of pesticides and herbicides into aquatic ecosystems.

A tool was developed to calculate chemical exposures for different Danish population groups. First, the tool divided the individuals into quartiles using a previously developed scoring system for how well their diet complies with the Danish dietary guidelines.

Abstract

Aims

Excessive boron (B) can pose toxicity to many plant species, and consequently restricts land utilization in B-laden regions. The purpose of this study was to identify “agretti” (Salsola soda) as an alternative B-tolerant food crop.

The Aryl Hydrocarbon Receptor (AhR) is a transcription factor that, when activated by ligand-binding, has been shown to regulate the immune response. Pertussis Toxin (PTX) is a virulence factor found in Bordetella pertussis, a human respiratory pathogen that causes whooping cough. PTX promotes colonization and disease promotion by triggering a heightened inflammatory response. The role of AhR in the regulation of PTX-mediated inflammation has not previously been studied.

Effect of base trehalose solution on quality of prepared weever during repeated freeze‐thaw cycles has been studied. L* (lightness), b* (yellowness), expressible moisture and total volatile base nitrogen (TVBN) of weever sample dipped in base trehalose solution reduced comparing with the control (without treatment), while pH, a* (redness), shear force, moisture content of treated samples increased (p ＜ .05) with the increased freeze‐thaw cycle.
