The current study investigated whether intermittent restraint stress (IRS) would impair fear extinction learning and lead to increased anxiety and depressive- like behaviors and then be attenuated when IRS ends and a post- stress rest period ensues for 6 weeks. Young adult, male Sprague Dawley rats underwent restraint stress using wire mesh (6hr/daily) for five days with two days off before restraint resumed for three weeks for a total of 23 restraint days. The groups consisted of control (CON) with no restraint other than food and water restriction yoked to the restrained groups, stress immediate (STR-IMM), which were restrained then fear conditioned soon after the end of the IRS paradigm, and stress given a rest for 6 weeks before fear conditioning commenced (STR-R6). Rats were fear conditioned by pairing a 20 second tone with a footshock, then given extinction training for two days (15 tone only on each day). On the first day of extinction, all groups discriminated well on the first trial, but then as trials progressed, STR-R6 discriminated between tone and context less than did CON. On the second day of extinction, STR- IMM froze more to context in the earlier trials than compared to STR-R6 and CON. As trials progressed STR-IMM and STR-R6 froze more to context than compared to CON. Together, CON discriminated between tone and context better than did STR-IMM and STR-R6. Sucrose preference, novelty suppressed feeding, and elevated plus maze was performed after fear extinction was completed. No statistical differences were observed among groups for sucrose preference or novelty suppressed feeding. For the elevated plus maze, STR-IMM entered the open arms and the sum of both open and closed arms fewer than did STR- R6 and CON. We interpret the findings to suggest that the stress groups displayed increased hypervigilance and anxiety with STR-R6 exhibiting a unique phenotype than that of STR-IMM and CON.

Monoamine neurotransmitters (e.g., serotonin, norepinephrine, and dopamine) are powerful modulators of mood and cognitive function in health and disease. We have been investigating the modulation of monoamine clearance in select brain regions via organic cation transporters (OCTs), a family of nonselective monoamine transporters. OCTs are thought to complement the actions of selective monoamine transporters in the brain by helping to clear monoamines from the extracellular space; thus, assisting to terminate the monoamine signal. Of particular interest, stress hormones (corticosterone; CORT) inhibit OCT3-mediated transport of monoamine, to putatively lead to prolonged monoamine signaling. It has been demonstrated that stress levels of CORT block OCT3 transport in the rat hypothalamus, an effect that likely underlies the rapid, stress-induced increase in local monoamines. We examined the effect of chronic variable stress (CVS) on the development of mood disorders and OCT3 expression in limbic and hypothalamic regions of the rat brain. Animals subjected to CVS (14-days with random stressor exposure two times/day) showed reduced body weight gain, indicating that CVS was perceived as stressful. However, behavioral tests of anxiety and depressive-like behaviors in rats showed no group differences. Although there were no behavioral effects of stress, molecular analysis revealed that there were stress-related changes in OCT3 protein expression. In situ hybridization data confirmed that OCT3 mRNA is expressed in the hippocampus, amygdala, and hypothalamus. Analysis of Western blot data by two-way ANOVA revealed a significant treatment effect on OCT3 protein levels, with a significant decrease in OCT3 protein in the amygdala and hippocampus in CVS rats, compared to controls. These data suggest an important role for CORT sensitive OCT3 in the reduction of monoamine clearance during stress.

The purpose of this thesis is to examine the relationship between mental illness and capitalist consumer society. Many Americans are suffering from mental illness and there has to be something causing it besides a chemical imbalance in the brain. A capitalist society creates a set of expectations that conflict with human desires. The thesis takes a historical, economical, and psychological approach to answering the following question: Does a capitalist society make its citizens mentally sick? A brief history of capitalism over the past century is discussed, as well as a more in depth look at capitalism and the creation of neoliberalism during the 1980s. The psychological effects capitalism has on human beings is discussed for the majority of the thesis and focuses on ideas from the 1950s as well as the early 2000s. To show the effect capitalism has on modern day society, an analysis of a psychopharmaceutical drug commercial is given. The concluding thoughts attempt to offer solutions to the problems of human unhappiness in a consumer culture.

Purpose: The purpose of this study was to determine the efficacy of a yoga intervention for adolescents suffering from depression. Secondary results regarding the viability of yoga as an intervention for increasing self-esteem and decreasing anxiety were also explored.

Methods: Using PubMed, Medline, and CINAHL the search terms adolescents, depression, and yoga were searched for related articles. Articles were then excluded or included based on certain criteria. Focus was placed on articles written within the last 10 years as well as studies done on children within 10-19 years of age. Final articles underwent extraction for relevant information and comparisons were drawn between the studies.

Results: Final exclusion lead to a total of 5 suitable studies. Studies varied in styles of yoga performed and measurement scales used to assess depression. Populations of adolescents varied significantly as well. The majority of these studies showed significant improvement in depression symptoms when measuring from pre to post intervention. Similar improvements were also noted in anxiety symptoms and low self-esteem.

Conclusion: Data gathered indicated that yoga serves a suitable intervention for decreasing depression symptoms in adolescents. Additionally, there seems to be promising results regarding the viability of yoga as an intervention for decreasing symptoms of anxiety and increasing self-esteem. Despite, current promising results, there is need for more research to affirm the findings found in these articles to determine the long term effects of yoga interventions.

Depression is a prominent world disorder. Many prior studies have examined the biological, cognitive, and social elements of depression; however, few studies attempt to examine what role culture plays in this disorder. If culture plays such a large role in human development, it only makes sense that it would have an impact on a society's depression experience. Furthermore, conformity has been found to play a large role in the behaviors and mood states of adolescents. If conformity holds such control within this population, it is likely that said conformity could be adapted to any decided behavior. Although there has been research conducted on depression, culture, and conformity separately, these concepts are not often looked at in unison. For this reason, the current thesis focuses on the interaction between depression, culture, and conformity by defining depression-culture and depression-conformity, examining the manifestation of these concepts within American society, and analyzing the effects of these concepts.

Depression is a worldwide public health problem that affects millions of people every year. Due to recent reports that depressed individuals have an altered gut microbiome composition, there is speculation that treatments that influence microorganisms in the gut could potentially lead to alleviation of depressive symptoms. Apple cider vinegar has been studied extensively for its health-promoting properties and benefits. Apple cider vinegar’s main ingredient is the short chain fatty acid, acetic acid. Short chain fatty acids have been shown to improve mood state and depressive symptoms, as well as amplify the effect of prebiotics in restoring the gut microbiome. This experimental design study examined the effects of ingesting 2 tbsp. apple cider vinegar (1 g acetic acid) twice daily with a meal on the levels of urinary metabolites in 14 college students compared to a control group of 11 college students that took one vinegar supplement tablet (0.015 g of acetic acid) daily for 28 days. All participants were healthy, normal to underactive (< 300 minutes of moderate exercise a week), and free of chronic or acute illnesses. Urinary metabolite analysis revealed a significant production of enzymes involved in the hexosamine pathway in the liquid vinegar group compared to baseline levels. However, anticipation of an alteration in tryptophan metabolites, a possible consequence of altered metabolism of gut microflora, was not observed. These data suggest that apple cider vinegar might be a potential treatment for depression through the production of hexosamine pathway enzymes.

The relevance of depression in the clinical realm is well known, as it is one of the most common mental disorders in the United States. Clinical depression is the leading cause of disease for women worldwide. The sex difference in depression and anxiety has guided the research of not just recent studies but older studies as well, supporting the theory that gonadal hormones are associated with the mechanisms of emotional cognition. The scientific literature points towards a clear correlative relationship between gonadal hormones, especially estrogens, and emotion regulation. This thesis investigates the neural pathways that have been indicated to regulate mood and anxiety. Currently, the research points to the hypothalamic-pituitary-adrenal axis, which regulates the stress response through its ultimate secretion of cortisol through the adrenal cortex, and its modulated response when exposed to higher levels of estrogen. Another mechanism that has been investigated is the interaction of estrogen and the serotonergic system, which is noteworthy because the serotonergic system is known for its importance in mood regulation. However, it is important to note that the research seeking to determine the neurobiological underpinnings of estrogen and the serotonergic system is not expansive. Future research should focus on determining the direct relationship between cortisol hypersecretion and estrogens, the specific neurobiological effects of serotonergic receptor subtypes on the antidepressant actions of estrogens, and the simultaneous effects of the stress and serotonergic systems on depressive symptoms.

With a prison population that has grown to 1.4 million, an imprisonment rate of 419 per 100,000 U.S. residents, and a recidivism rate of 52.2% for males and 36.4% for females, the United States is facing a crisis. Currently, no sufficient measures have been taken by the United States to

With a prison population that has grown to 1.4 million, an imprisonment rate of 419 per 100,000 U.S. residents, and a recidivism rate of 52.2% for males and 36.4% for females, the United States is facing a crisis. Currently, no sufficient measures have been taken by the United States to reduce recidivism. Attempts have been made, but they ultimately failed. Recently, however, there has been an increase in experimentation with the concept of teaching inmates basic computer skills to reduce recidivism. As labor becomes increasingly digitized, it becomes more difficult for inmates who spent a certain period away from technology to adapt and find employment. At the bare minimum, anybody entering the workforce must know how to use a computer and other technological appliances, even in the lowest-paid positions. By incorporating basic computer skills and coding educational programs within prisons, this issue can be addressed, since inmates would be better equipped to take on a more technologically advanced labor market.<br/>Additionally, thoroughly preparing inmates for employment is a necessity because it has been proven to reduce recidivism. Prisons typically have some work programs; however, these programs are typically outdated and prepare inmates for fields that may represent a difficult employment market moving forward. On the other hand, preparing inmates for tech-related fields of work is proving to be successful in the early stages of experimentation. A reason for this success is the growing demand. According to the U.S. Bureau of Labor Statistics, employment in computer and information technology occupations is projected to grow 11 percent between 2019 and 2029. This is noteworthy considering the national average for growth of all other jobs is only 4 percent. It also warrants the exploration of educating coders because software developers, in particular, have an expected growth rate of 22 percent between 2019 and 2029. <br/>Despite the security risks of giving inmates access to computers, the implementation of basic computer skills and coding in prisons should be explored further. Programs that give inmates access to a computing education already exist. The only issue with these programs is their scarcity. However, this is to no fault of their own, considering the complex nature and costs of running such a program. Accordingly, this leaves the opportunity for public universities to get involved. Public universities serve as perfect hosts because they are fully capable of leveraging the resources already available to them. Arizona State University, in particular, is a more than ideal candidate to spearhead such a program and serve as a model for other public universities to follow. Arizona State University (ASU) is already educating inmates in local Arizona prisons on subjects such as math and English through their PEP (Prison Education Programming) program.<br/>This thesis will focus on Arizona specifically and why this would benefit the state. It will also explain why Arizona State University is the perfect candidate to spearhead this kind of program. Additionally, it will also discuss why recidivism is detrimental and the reasons why formerly incarcerated individuals re-offend. Furthermore, it will also explore the current measures being taken in Arizona and their limitations. Finally, it will provide evidence for why programs like these tend to succeed and serve as a proposal to Arizona State University to create its own program using the provided framework in this thesis.

Latinas face among the highest documented rates of depressive symptoms among all adolescent groups. According to the Centers for Disease Control and Prevention's 2018 Youth Risk and Behavior Survey, 46.8% of Latina adolescents reported feeling sad and hopeless on a daily basis. As a Latina myself, I found myself wondering how we could direct power back to our Latina youth. I turned to the tradition of storytelling, an integral practice in Latino/a communities. Storytelling is a social and cultural tradition, which upholds intergenerational connection, understanding, and education. While many Latinas engage with storytelling in the family space, I wanted to foster a safe space outside of the household for Latinas to connect with one another. I was inspired by psychologist Dr. Lillian Comas-Diaz's concept "Spirita," a synthesizing spirituality among women of color which places emphasis on understanding the shared traumatic experiences and drawing joy from empathetic connections and commitment to creating community with one another. From here, I developed a website called "Sanando Juntos," or "Healing Together," teaching Latinas how to use storytelling as a tool to better understand themselves as well as create a space to foster connections with other Latinas. In order to develop a theoretical framework for the website, a literature review was conducted observing successful methods of digital storytelling in adolescent audiences. I then used this research to develop the main pillars for the website, a storytelling workshop, safe-space building, multimedia approaches, and peer-to-peer interaction. With many young Latina girls disproportionately suffering from suicidal ideation and depression, Sanando Juntos acts as a way to break down the stigma surrounding these difficult conversations while empowering and connecting like-minded Latinas. The final website can be viewed at https://sanandojuntos.com.
