My research aims to determine the effectiveness of meditation and sleep applications (apps) on the reduction of anxiety and stress in college students, with a focus on sedative piano music. Results showed a significant reduction of stress and anxiety levels in college students when listening to sedative piano music versus non-sedative piano music. Music along with other therapy modalities in meditation and sleep apps show promise in reducing students’ anxiety and stress and promoting their successes.
Premature babies are at risk of death from immature lung development. For this reason, pregnant mothers at risk for preterm delivery are administered dexamethasone (DEX), a synthetic glucocorticoid that promotes fetal lung development. However, exposure to DEX in utero is associated with low birth weight and cardiovascular development pathologies. Moreover, our lab found that DEX administration in-utero leads to a sex-specific increase in stress-induced tachycardia in female, but not male offspring. This project seeks to expand on this preliminary finding of the heart by examining local effectors of activity from the sympathetic system (tyrosine hydroxylase and catechol-o-methyltransferase). Tyrosine hydroxylase was measured as it catalyzes the rate limiting step of norepinephrine synthesis while catechol-O- methyltransferase was studied as it catalyzes the degradation of norepinephrine. Acetylcholinesterase was used to measure parasympathetic activity as it catalyzes the degradation of the primary neurotransmitter of the parasympathetic nervous system, acetylcholine. Analyses of sympathetic as well as parasympathetic activity were done to determine influences of in-utero DEX exposure on autonomic regulation in adulthood. Pregnant rats were administered DEX (0.4 mg/kg, i.p.) or vehicle (20% w/v 2-hydroxypropyl ß- cyclodextran) at gestation days 18-21, with euthanasia of offspring occurring at around the time the offspring reached 13-15 weeks of age. Left ventricles and right atria were pulverized, processed and subjected to western blot analysis to determine expression of proteins of interest. Males exposed to DEX in-utero saw a decrease in tyrosine hydroxylase expression in left ventricle and right atrium when compared to vehicle control, a difference not seen with females. In addition, catechol-o-methyltransferase expression was increased in right atria from male, but not female rats. Acetylcholinesterase expression was reduced in the right atria of female, but not male rats. The present findings suggest reduced norepinephrine signaling in the heart of male, but not female DEX-exposed offspring. Given that we have previously found that female, but not male rats exhibit exaggerated stress-induced tachycardia, our current findings suggest that males possess a sex-specific compensatory mechanism allowing the heart to resist increased sympathetic signaling from the brain, one that females do not possess. The underlying mechanics of this proposed mechanism are unclear, and further investigation is needed in this subject to determine the significance of the findings from our study.
Majority of the CA young adults have perceived racial/ethnic discrimination in the community. Furthermore, perceived discrimination has been positively associated with their depressive and somatic symptoms, suggesting a need to address racial/ethnic discrimination issues to promote positive mental health in this population. It is important for school/work personnel and healthcare providers to assess CA young adults’ discrimination experiences, and have the sufficient resources (e.g., education, support groups) to prevent negative consequences associated with discrimination.
The Latinx community faces several barriers that keep them from seeking mental health treatment. One of those barriers is the stigma experienced in the community. The purpose of this project is to create a culturally tailored animation to address the stigma associated with mental health in the Latinx community. The first part of the project, written about in this paper, focuses on gathering data from the community about their beliefs, attitudes, and behaviors regarding mental health, as well as the stigma they have witnessed and experienced. Information was gathered through a series of group and one-on-one interviews with Generation Z men and women that identified as Latinx. The preliminary results revealed that all participants agreed with the statement that mental health is stigmatized in their community and offered several reasons as to why this is the case. The majority of them also agreed that education is the best way to reduce the stigma, which is what we hope to achieve through an animation that will be created using the information provided by the community and the literature.
