One sediment core spanning approximately 138 years was taken from the muddy deposits along the Zhejiang coast of the East China Sea, which is located in a hypoxic zone south of the Yangtze River estuary. When the sources of the trace metals in the core were analyzed, the three geochemical sources were identified as lithogenic, anthropogenic, and reductive deposits based on both principal component analysis and the ratios of terrigenous elements. The temporal distribution of the enrichment factor of copper in the sediment core matches the timeline of economic development and national policy in China. The rapid increase in human activity and economic development in the Yangtze River catchment accounts for the enrichment of copper in the sediment core. Based on the vertical distribution of arsenic concentration, the hypoxic zone south of the Yangtze River estuary may have not only existed, but worsened since 1875.

Aim: To explore the holistic impact of socioeconomic and mental health inequalities on the global burden of type 2 diabetes.
Materials And Methods: This cross-sectional study used data on the incidence, disability-adjusted life years (DALYs), and mortality of type 2 diabetes as well as DALYs attributable to risk factors during 1990-2021 from the Global Burden of Disease Study 2021. Average annual percent change (AAPC) was applied to assess the temporal trends from 1990 to 2021.

Food security is the foundation of national security, which is related to economic development and social stability. Shanxi Province, as China's grain production and marketing balance area, has rich agricultural resources and profound farming civilization, its food security situation is not only related to its own economic development, but also has a strategic position that can not be ignored in the national food security system. Based on the concept and goal of the development of food security in Shanxi Province, from the five aspects of quantity security, economic security, policy security, resource sustainability and ecological sustainability, this paper constructs the evaluation index system of food security in Shanxi Province, including the fluctuation rate of grain production and the sown area of grain, and establishes the entropy TOPSIS model to evaluate the development level of food security in Shanxi Province.

In recent times, a truly exquisite pharmaceutical marvel has graced the world of medicine, known as Safinamide (SAF). This opulent creation has been specifically tailored to cater to the needs of individuals afflicted with Parkinson's disease (PD), an esteemed neurological condition renowned for its regal ability to impede motor skills, coordination, and equilibrium. It is highly improbable that degradation products of pharmaceutical components would significantly compromise efficiency and safety of a drug during its shelf life.

Background: Plants produce abundant natural products, among which are species-specific and diversified secondary metabolites that are essential for growth and development, as well as adaptation to adversity and ecology. Moreover, these secondary metabolites are extensively utilized in pharmaceuticals, fragrances, industrial materials, and more. WRKY transcription factors (TFs), as a family of TFs unique to plants, have significant functions in many plant life activities.
