Parent-child relationship and junior high academic performance: Differentiated impacts of fathers and mothers with self - efficacy as a mediator.

This study aimed to address the overlooked differences in the effects of father-child and mother-child relationships on junior high school students' academic performance. Utilizing data from the China Education Panel Survey, it explored these relationships' impacts on overall and subject-specific academic achievements and the mediating role of self-efficacy.

Infant's action skill dynamically modulates parental action demonstration in the dyadic interaction.

When interacting with infants, human adults modify their behaviours in an exaggerated manner. Previous studies have demonstrated that infant-directed modification affects the infant's behaviour. However, little is known about how infant-directed modification is elicited during infant-parent interaction.

The GSTM1 null genotype increased risk of gastric cancer: a meta-analysis based on 46 studies.

Background: Glutathione S-transferases M1 (GSTM1) is an important phase II metabolizing enzyme. The null genotype of GSTM1 causes total loss of GSTM1 enzyme activity and numerous studies have investigated the association between GSTM1 null genotype and gastric cancer risk.

Methods: This meta-analysis was designed to investigate the relationship between GSTM1 null genotype and susceptibility to gastric cancer and assess the influence of Helicobacter pylori infection, smoking, Lauren's classification, and other factors.
