A Method to Visualize Cell Proliferation of <i>Arabidopsis thaliana</i>: A Case Study of the Root Apical Meristem. [PDF]
Plant DirectABSTRACT Plant growth and development rely on a delicate balance between cell proliferation and cell differentiation. The root apical meristem (RAM) of Arabidopsis thaliana is an excellent model to study the cell cycle due to the coordinated relationship between nucleus shape and cell size at each stage, allowing for precise estimation of the cell ...

Adverse childhood experiences and developmental disabilities: risks, resiliency, and policy
Developmental Medicine &Child Neurology, Volume 63, Issue 10, Page 1149-1154, October 2021., 2021 Thanks to the seminal work of Robert Anda and Vincent Felitti, it is now widely accepted that adverse childhood experiences (ACEs) can have lifelong effects on physical, behavioral, and mental health and that many adult diseases can be considered developmental disorders that began early in life.

Meta‐analysis of genome‐wide DNA methylation and integrative omics of age in human skeletal muscle
Journal of Cachexia, Sarcopenia and Muscle, Volume 12, Issue 4, Page 1064-1078, August 2021., 2021 Abstract Background Knowledge of age‐related DNA methylation changes in skeletal muscle is limited, yet this tissue is severely affected by ageing in humans. Methods We conducted a large‐scale epigenome‐wide association study meta‐analysis of age in human skeletal muscle from 10 studies (total n = 908 muscle methylomes from men and women aged 18–89 ...

¿Lo que comemos puede cambiar la expresión de nuestros genes?
Biociencias, 2021 La epigenética es el estudio de procesos moleculares heredables y reversibles que regulan la expresión génica sin afectar directamente la secuencia del ADN. Estos procesos moleculares pueden estar sujetos a variaciones que dependen del
