[Effects of Soil Acidification on the Distribution and Availability of Arsenic in Aggregates].

The spatiotemporal substitution method was used to collect yellow soil and purple soil with different acidification degrees； analyze the effects of acidification on the composition and properties of soil aggregates； explore the distribution characteristics, occurrence forms, and availability of arsenic （As） in soil aggregates with different acidification degrees； and reveal the key factors restricting the availability of soil As. The results showed that the distribution of total As in each aggregate was positively affected by its mass fraction, and the larger the mass fraction, the more the total As distribution. Soil acidification destroyed the aggregate structure, reduced the mass fraction of large aggregate S1 （>2 mm） by 5 to 15 percentage points, led to the increase in amorphous iron content by 2 to 7 times, and decreased the total As distribution of S1.

[Influences of Acidification on the Allocation and Availability of Lead and Cadmium within Soil Aggregates].

Soil aggregates, the fundamental units of soil structure, crucially regulate soil physicochemical properties. Acidification alters soil aggregation, impacting heavy metal distribution and availability within aggregates. This study explores aggregate composition in differently acidified yellow and purple soils, along with the variation in the distribution and availability of cadmium （Cd） and lead （Pb） in different-sized aggregates.

Consumption of a Taiwanese cafeteria diet induces metabolic disorders and fecal flora changes in obese rats.

Objectives: Among diet-induced obesity animal models, the cafeteria diet, which contains human junk food and processed foods, is a popular experimental animal diets in Western countries. Consumption of a cafeteria diet can lead to the development of obesity and non-alcoholic liver disease in as soon as 2 mo, which more accurately reflects human eating patterns. The aim of this study was to establish a Taiwanese cafeteria diet and compare it with a traditional lard-based, 60% high-fat diet in a 12-wk animal model.

[Research Advances in Barrier Technology of Paddy Soil Co-contaminated with As and Cd].

Arsenic (As) and cadmium (Cd) are the most common toxic and harmful heavy metal elements in paddy soils and are easily transferred from the soil to grains. At present, As and Cd and their co-contamination in paddy soils in China are widespread, posing a serious threat to food security and human health. As and Cd have opposite environmental behaviors in soil, and the simultaneous remediation of co-contamination with As and Cd is a current technical difficulty for safe rice production.

Orthographic Processing of Developmental Dyslexic Children in China: Evidence from an Event-Related Potential Study.

Objective: This study aimed to explore the orthographic processing of simplified Chinese characters in developmental dyslexic children in Kashgar, Xinjiang, China, and provide a theoretical basis for intervention strategies for developmental dyslexia in Chinese.

Methods: Using event-related potential (ERP) measures, 18 developmental dyslexic children and 23 typically developing children performed a character decision task with three types of stimuli: real characters (RCs), pseudocharacters (PCs), and noncharacters (NCs).

Results: Behavioral results showed that the control children displayed a faster and higher accurate performance than the dyslexic children across PCs and NCs.
