Medicine (Baltimore) · 2024 · Meta-analysis / systematic review
The concept of folic acid supplementation and its role in prevention of neural tube defect among pregnant women: PRISMA

Conclusion: As a result, women are recommended to take 400 microgram FA/day from preconception until the end of the first trimester to prevent NTD-affected pregnancies. This allows the developing neural tissue to acquire critical mass and provides the preferred rostrocaudal orientation so that these divisions contribute to the elongation of the developing neural tube in embryos.

Genome-wide study of DNA methylation shows alterations in metabolic, inflammatory, and cholesterol pathways in ALS

Conclusion: Integration of these results with our latest genome-wide association study showed that cholesterol biosynthesis was potentially causally related to ALS. Last, DNA methylation at several DMPs and blood cell proportion estimates derived from DNA methylation data were associated with survival rate in patients, suggesting that they might represent indicators of underlying disease processes potentially amenable to therapeutic interventions.

Environmental contaminant-mixture effects on CNS development, plasticity, and behavior

Conclusion: These indices serve as templates for learning and memory, and as such, from a vulnerability perspective, may serve as targets for dysregulation during development in susceptible populations that have been disproportionately exposed to these contaminants. Included in this review is also a discussion of the relevance of developing biomarkers for use within the framework of cumulative risk-assessment.

MicroRNAs (MiRs) Precisely Regulate Immune System Development and Function in Immunosenescence Process

Conclusion: Effect of miRs on impairment of immune system function due to the aging is emerging. Although it has been accepted that miRs have determinant roles in the regulation of the immunosenescence; however, most of the reports are concluded from animal/laboratory works, suggesting the necessity of more investigations in human.
