The main purpose of the study was to find a three-way interaction between genotype, treatment and interacted subjects. Interestingly, and not expected, the KO*MIA rats spent more time with the pups compared to time spent with the male rat. This unexpected results from this study are evidence that there is a complex spectrum of behavioral symptoms due to genetics, environment and their interactive effect (Schwartzer et aI., 2013). For that reason, the interaction between genetics (DISCI) and environment (MIA) might be more complex than what is believed.

• Depression has the greatest impact on daily functioning capability of all diseases and adversely effects individuals globally (Flint & Kendler, 2014). • Human capital value of these losses has been about $40 billion dollars annually (Kessler, 2012). • Analysis of the genetic and biological systems associated with depressive symptoms, such as the oxytocin system, could lead to identifying risk variants and possible treatment development. • Genetic Variation in OXTR is associated with a variation in depressive symptoms including low selfesteem, pessimism, and low self-efficacy, etc. (Conner et al., 2018). • The A allele of the SNP rs53576 is considered …

Nature As A Buffer: The Physiological Effects Of Exposure To Nature On Stress, Tyler J. Stading, Jeffrey R. Stevens

UCARE Research Products

Exposure to images of nature following a stressful event can reduce physiological measures associated with stress. The objectives of this study was to determine whether exposure to nature before the stressor can buffer the stress response. We varied whether nature or urban images were viewed before or after a stressor and measured galvanic skin response in our participants. We describe how order of presenting the stressor influences nature’s calming effect on physiology.

• The prevalence of alcohol disorders costs Americans $223.5 billion yearly due mostly from losses in workplace productivity, as well as health care and criminal justice expenses (CDC, 2016).

• Maximum number of drinks consumed in a 24 hour period is a valid indicator of dangerous drinking behavior and may reflect an increased tolerance for high levels of alcohol (Edenberg, 2016).

• Awareness of factors related to such heavy drinking is important for targeting interventions for dangerous alcohol use.

• Men drink significantly more than women, with about 4.5% of men and 2.5% of women meeting the diagnostic criteria for …
