Impact of Maternal Exposure to Trace Metal Mixtures on Bone Mineral Density in Children Aged 3-6: Results from the Guangxi Zhuang Birth Cohort, China.

Prospective studies examining early maternal exposure to trace metal (TM) mixtures and their effects on offspring remain limited. We analyzed data regarding maternal plasma trace metal concentrations and bone mineral density (BMD) for 220 children aged 3-6 years from the Guangxi Zhuang Birth Cohort. Inductively coupled plasma-mass spectrometry was used to measure 22 trace metal concentrations-Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Mo, Cd, Sb, Cs, Ba, W, Tl, Pb, and U-in maternal plasma samples collected before 13 weeks of gestation.

Prevalence of Hypertension and Associated Factors among Residents Aged ≥18 Years in Ganzhou, China: A Cross-Sectional Study.

Background: Reliable epidemiologic data on the present burden of hypertension are needed in developing region-specific strategies since previous studies have suggested that China is lagging in risk factor management.

Objective: The study aimed at exploring the prevalence of hypertension and its associated factors among adult residents in Ganzhou, China. .

Causal Paradigm Between Common Comorbidities of Cardiovascular and Metabolism-Related Diseases in Elderly: Evidence from Cross-Sectional and Mendelian Randomization Studies.

Background: Comorbidity is a common problem among elderly people, significantly damaging individuals' health and healthcare systems. However, observational studies may be susceptible to residual confounding factors and bias. The present study aimed to assess the causal effect of common chronic disease comorbidity using the Mendelian randomization (MR) approach.

Relationship between body dissatisfaction, insufficient physical activity, and disordered eating behaviors among university students in southern China.

Background: With an increasing incidence of obesity, the relationship between obesity and body image has become a hot research topic worldwide. From high school to university, young people experience changes in their social environment. University students have a high incidence of eating disorders and insufficient physical activity.

Analyzing Risk Communication, Trust, Risk Perception, Negative Emotions, and Behavioral Coping Strategies During the COVID-19 Pandemic in China Using a Structural Equation Model.

Objective: Risk communication and the degree of trust are major factors that affect the public's behavioral coping strategies and play an important role in emergency risk management. However, the internal formation mechanism involved in the public's psychological behavior remains unclear. This study aimed to investigate the association among risk communication, trust, risk perception, negative emotions, and behavioral coping strategies during the coronavirus disease 2019 (COVID-19) pandemic, and to identify and quantify the factors that influence public behavior.

RyRs mediate lead-induced neurodegenerative disorders through calcium signaling pathways.

Heavy metal lead (Pb) is widely distributed in the environment and can induce neurodegeneration. Accumulating evidence has shown that ryanodine receptors (RyRs) play vital roles in neurodegenerative brain. However, whether aberrant RyRs levels contribute to Pb-induced neurodegeneration has largely remained unknown.

Lead exposure-induced cognitive impairment through RyR-modulating intracellular calcium signaling in aged rats.

Lead is widely distributed in the environment and has become a global public health issue. It is well known that lead exposure induces not only neurodevelopmental toxicity but also neurodegenerative diseases, with learning and memory impairment in the later stage. However, the molecular mechanisms remain elusive.

Pb modulates ryanodine receptors from the endoplasmic reticulum in rat brain.

Although the neurotoxic mechanism of lead (Pb) has been extensively studied, it is not well understood. The effects of Pb on free cytosolic calcium (Ca) concentration and calcium-regulated events have been suggested to be major mechanisms in Pb toxicity. Based on our previous findings that Pb changes calcium release through ryanodine receptors (RyRs), the modulation of endoplasmic reticulum (ER) vesicular RyRs by Pb was investigated further in the present study.

dbMDEGA: a database for meta-analysis of differentially expressed genes in autism spectrum disorder.

Background: Autism spectrum disorders (ASD) are hereditary, heterogeneous and biologically complex neurodevelopmental disorders. Individual studies on gene expression in ASD cannot provide clear consensus conclusions. Therefore, a systematic review to synthesize the current findings from brain tissues and a search tool to share the meta-analysis results are urgently needed.

The effect of lead exposure on expression of SIRT1 in the rat hippocampus.

Based on how the silent information regulator 2 homolog 1 (SIRT1) regulates the cyclic AMP response element binding protein (CREB), which is the molecular switch of long-term memory that maintains cognitive function, it is postulated that the impact of lead (Pb) on SIRT1 is one of the mechanisms leading to Pb-induced cognitive and learning deficits. Hence, the purpose of this study was to investigate the effect of Pb exposure on the expression of SIRT1, and the reversion effect of resveratrol, which is an activator of SIRT1. We examined the effects of maternal rat ingestion of Pb in drinking water during gestation and lactation on the expression of SIRT1 and CREB in the hippocampus of their offspring at postnatal week 3 (PNW3) and 52 (PNW52), and then reexamined these effects in offspring after intragastric administration of resveratrol for 4 weeks.
