Migrant parent-child separation in the first three years of life and mental health problems at preschool age: A cross-sectional study.

Background: Parent-child separation is one of the adverse childhood experiences, becoming more common due to economic migration worldwide today. However, there is a lack of understanding of the association between this separation during the critical first three years of life and the development of mental health issues in early childhood. This study aimed to determine the association of parent-child separation in the first three years and its specific patterns with mental health problems that emerged at preschool age.

Ferrihydrite sulfidation transformation and coupled As(V) and Cd(II) mobilization under anoxic conditions.

Ferrihydrite sulfidation is an important process influencing the environmental behavior of co-existent arsenate (As(V)) and cadmium (Cd(II)) pollutants in mining-impacted environments. However, the mineral evolution of ferrihydrite and the coupled mobilization behavior of co-existent As(V) and Cd(II) remain unclear. In this study, we have investigated As(V)-Cd(II)-bearing ferrihydrite conversion behavior induced by environmentally relevant concentrations of S(-II) (1 and 5 mM).

Stability and transformation behavior of hydrometallurgical hazardous arsenic-calcium residue in sulfidic anoxic environments.

Arsenic-calcium residue (ACR) is a hazardous solid waste generated by the metallurgical industry, posing a significant environmental risk. However, the stability and transformation behavior of ACR in sulfidic conditions remains unclear. Herein, we have investigated the stability and speciation evolution of arsenic (As), sulfur (S), and trace metals during the exposure of ACR to diverse S(-II) concentrations under anoxic conditions at pH of 6 and 11.

Impact of climate risk on global energy trade.

Climate risk is one of the key factors affecting the energy industry, and then affects the global energy trade. By adopting a network approach to the global energy trade and based on the data of global energy trade during 1996-2018, the evolution characteristics of the global energy trade network are hereby investigated, and the impact of climate risk on the global energy trade is explored. The results demonstrate that the global energy trade network has scale-free characteristics and significant regional characteristics and that its heterogeneity is weakening on the whole.

Prospect of the QTL-qSB-9Tq utilized in molecular breeding program of japonica rice against sheath blight.

The major QTL-qSB-9(Tq) conferring partial resistance to rice (Oryza sativa L.) sheath blight (Rhizoctonia solani Kühn) has been verified on chromosome 9 of the indica rice cultivar, Teqing. In this study, the prospect of this QTL utilized in molecular breeding program of japonica rice for sheath blight resistance was investigated.

[Effects of Pollen Typhae total flavone on glucose and lipid metabolism in 3T3-L1 adipocytes].

Objective: To observe the effects of Pollen Typhae total flavone (PTF) on glucose and lipid metabolism in 3T3-L1 adipocytes.

Methods: The content of glucose which disappeared from the culture medium after incubation with drugs for 24 hours was determined as glucose consumption of the cells. The activity of cells was detected by XTT method.
