Chronic stress exposure among young African American children with asthma: Racism is a factor

Hair cortisol concentration analysis provides an alternative to traditional measures of cortisol; however, to collect hair samples from African Americans, scientists need to be culturally informed and competent. The purpose of this protocol is to demonstrate a culturally informed technique to collect hair samples for cortisol analysis from African...

Source: Yan, Z., et al. Evaluating the Anti-depression Effect of Xiaoyaosan on Chronically-stressed Mice. J. Vis. Exp. (2019).The video demonstrates the process of establishing a mouse model of chronic stress-induced depression and assessing depressive behaviors. The chronic application of various stressors triggers the release of corticosterone, leading to neuronal over-excitation and eventual neuronal death, which results in depression-like symptoms in the...

Here, we present a protocol that provoked cortisol reactivity in a vulnerable adolescent Mexican American sample utilizing a modified version of the Trier Social Stress Test (TSST). Saliva samples were collected at baseline, 15, 30, and 45 min post-TSST onset. Future research could utilize this modified TSST with vulnerable...

This publication demonstrates methods for successful sampling and culture of nasal epithelial mucosa from children, and reprogramming these cells to induced Pluripotent Stem Cells...

The protocol describes a study of the systemic and local skin effects of Ultraviolet B exposure in mice.

A high platform can fix rats without restriction and completely expose the acupoints on the back during acupuncture manipulation. This article describes methods for the fabrication of the high platform, establishes a rat model of asthma and measures changes in respiratory function using a noninvasive and real-time whole-body plethysmography (WBP)...
