Geographical Variation in Total and Inorganic Arsenic Content of Polished (White) Rice

Verified

Andrew A. Meharg, Paul N. Williams, Eureka Adomako, Youssef Y. Lawgali et al.

Journal: Environmental Science & TechnologyYear: 2009Citations: 772

An extensive data set of total arsenic analysis for 901 polished (white) grain samples, originating from 10 countries from 4 continents, was compiled. The samples represented the baseline (i.e., notspecifically collected from arsenic contaminated areas), and all were for market sale in major conurba...

Inorganic Arsenic in Rice Bran and Its Products Are an Order of Magnitude Higher than in Bulk Grain

Verified

Guo‐Xin Sun, Paul N. Williams, Anne‐Marie Carey, Yong‐Guan Zhu et al.

Journal: Environmental Science & TechnologyYear: 2008Citations: 303

Rice is more elevated in arsenic than all other grain crops tested to date, with whole grain (brown) rice having higher arsenic levels than polished (white). It is reported here that rice bran, both commercially purchased and specifically milled for this study, have levels of inorganic arsenic, a no...

Interactions between cerium dioxide nanoparticles and humic acid: Influence of light intensities and molecular weight fractions

Verified

Hongliang Dai, Tongshuai Sun, Ting Han, Xiang Li et al.

Journal: Environmental ResearchYear: 2021Citations: 15

Cerium dioxide nanoparticles (CeO2 NPs) are ubiquitous in the water environment due to the extensive commercial applications. The complexity of heterogeneous humic acid (HA) plays a significant role in affecting the physicochemical properties of CeO2 NPs in aqueous environments. However, the effects...

Magnetic Microrobot With Drilling‐Sensing Dual Functionality for Targeted Biopsy of Deep‐Seated Tracheal Microlesions

Verified

Yong Wang, Dongdong Jin, Xiaoxia Liu, Lin Lin et al.

Journal: Advanced MaterialsYear: 2025Citations: 2

Biopsy remains gold standard for definitive diagnosis of numerous diseases, yet conventional approaches confront inherent limitations encompassing procedural invasiveness, limited spatial resolution, poor deep-tissue accessibility, and complicated post-operative histopathology examinations. Herein, ...

The Aldehyde Dehydrogenase 2 rs671 Variant Enhances Platelet Activation and Arterial Thrombosis

Verified

Song Sun, Xi Zhang, Hongwei Yue, Cuiqin Fan et al.

Journal: CirculationYear: 2026

BACKGROUND: Acute myocardial infarction (AMI) caused by thrombosis is a major cause of mortality. A polymorphism in Aldh2 gene (rs671) is found in approximately 30% to 50% of East Asians, and it is a risk factor for AMI. This mutation impairs aldehyde dehydrogenase 2 (ALDH2) function, but the effect...

Turning point identification via exploring the thickness dependence of magnetoresistance in polycrystalline Fe3O4 thin films

Verified

Wenhao Dong, Xiaoman Chen, Qingjie Guo, Xin Li et al.

Journal: Journal of Applied PhysicsYear: 2025

Stoichiometric polycrystalline Fe3O4 films with thicknesses ranging from 25 to 165 nm were fabricated on Si (100) substrates with a native SiO2 layer via pulsed laser deposition, followed by vacuum annealing at 780 °C. Negative magnetoresistance was observed, and the absolute magnetoresistance under...
