Description
Plants are essential to human life. They release oxygen into the atmosphere for us to breathe. They also provide shelter, medicine, clothing, tools, and food. For many people, the food that is on their tables and in their supermarkets isn't given much thought. Where did it come from? What part of the plant is it? How does it relate to others in the plant kingdom? How do other cultures use this plant? The most many of us know about them is that they are at the supermarket when we need them for dinner (Nabhan, 2009) (Vileisis, 2008).

Description
Restraint stress is the most commonly used laboratory stressor. It is difficult to characterize as psychological or physical, because past studies show psychological features, but the nature of confinement adds a physical dimension. This was the first study to investigate how experience with restraint stress affects brain response to the next stress without a physical burden. Pair-housed adult male rats were transported to a novel context and restrained or left undisturbed (6hr). The next day, rats were returned to the same context and were either restrained or left undisturbed in the context (n=8/group). After 90min, rats were euthanized to determine functional activation in limbic structures using Fos immunohistochemistry and to measure HPA axis reactivity through blood serum corticosterone levels. Regardless of day 1 experience, context exposure on day 2 enhanced Fos expression in CA1 and CA3 of the hippocampus, basolateral amygdala, and central amygdala. Conversely, other regions and corticosterone levels demonstrated modulation from the previous day's experience. Specifically, rats that were placed back into the restraint context but not restrained on day 2 showed enhanced Fos expression in the dentate gyrus suprapyramidal blade (DGSup), and infralimbic cortex (IL). Also Fos expression was attenuated in rats that received two restraint exposures in the IL and medial amygdala (MEA), suggesting habituation. Only the DG infrapyramidal blade (DGInf) showed enhanced Fos expression to restraint on day 2 without influence of the previous day. While context predominately directed Fos activation, prior experience with restraint influenced Fos expression in the DGSup, IL, MEA and corticosterone levels to support restraint having psychological components.

Description
This project looks at ways in which the individual comes into contact with history. By looking at the Katyń Massacre, we can see how violence and history can be viewed from aesthetic perspectives. This allows us to take part in the conversations concerned with genocide in other ways than from ethical and sympathetic perspectives. By examining the Katyń through an aesthetic lens, the individual can approach violence in new and unique ways. This research highlights for us a new way of approaching history and violence while simultaneously offering a way for the individual to have a new voice in history. The poetry that follows the research offers a way for us to aestheticize violence and use language to approach it in a way that is simultaneously cruel and beautiful.

Description
Abstract: Behavioral evidence suggests that joint coordinated movement attunes one's own motor system to the actions of another. This attunement is called a joint body schema (JBS). According to the JBS hypothesis, the attunement arises from heightened mirror neuron sensitivity to the actions of the other person. This study uses EEG mu suppression, an index of mirror neuron system activity, to provide neurophysiological evidence for the JBS hypothesis. After a joint action task in which the experimenter used her left hand, the participant's EEG revealed greater mu suppression (compared to before the task) in her right cerebral hemisphere when watching a left hand movement. This enhanced mu suppression was found regardless of whether the participant was moving or watching the experimenter move. These results are suggestive of super mirror neurons, that is, mirror neurons which are strengthened in sensitivity to another after a joint action task and do not distinguish between whether the individual or the individual's partner is moving.

Description
Background: Latinos represent 40.8% of the population in Phoenix (U.S. Census Bureau Population Division, 2010). South Phoenix, also known as the South Mountain Village, defined in geographical terms as area zip codes 85040 and 85042; is a predominantly Latino community comprised of mixed citizenship status households. During the 2010 United States Census 60.3% of the population in South Phoenix identified as Latino, 25.75% of the total population was foreign born. Of the foreign born population, 88.95% were of Latin American origin (United States Census Bureau, 2007-2011 American Community Survey). Understanding how Latino immigrants perceive differences in health between their communities in country of origin and communities in the United States is largely unknown. Irrespective of political positions, understanding how Latino immigrants perceive personal health and the health of their communities is of interest to inform public policy and implement needed interventions in the
public health sphere.
Methods: Semi-structured interviews were collected from 55 adults from the South Phoenix community between November 2009 and September 2010. Interviews were digitally recorded with participant permission and transcribed. Of those collected, 48 transcribed interviews were analyzed using a codebook designed by the researcher. Percent agreement evaluated inter-rater reliability.Results: Latino immigrants in South Phoenix largely agree that health quality is heavily dependent on personal responsibility and not an intrinsic attribute of a given place. Emotional contentedness and distress, both factors of mental health, are impacted by cross-cultural differences between Latino and U.S. culture systems.
Conclusions: As people’s personal perceptions of differences in health are complex concepts influenced by personal backgrounds, culture, and beliefs, attempting to demark a side of the border as ‘healthier’ than the other using personal perceptions is overly simplified and misses central concepts. Instead, exploration of individual variables impacting health allowed this study to gain a more nuanced understanding in how people determine quality of both personal and environmental health. While Latino migrants in South Phoenix largely agree that health is based on personal responsibility and choices, many nonetheless experience higher levels of contentedness and emotional health in their country of origin.

Description
Identifying disease biomarkers may aid in the early detection of breast cancer and improve patient outcomes. Recent evidence suggests that tumors are immunogenic and therefore patients may launch an autoantibody response to tumor associated antigens. Single-chain variable fragments of autoantibodies derived from regional lymph node B cells of breast cancer patients were used to discover these tumor associated biomarkers on protein microarrays. Six candidate biomarkers were discovered from 22 heavy chain-only variable region antibody fragments screened. Validation tests are necessary to confirm the tumorgenicity of these antigens. However, the use of single-chain variable autoantibody fragments presents a novel platform for diagnostics and cancer therapeutics.

Description
Time spent alone is a topic that has been studied in great detail, particularly the manner in which it is spent and the effect it has during the adolescent stage of life. Similarly, stress levels in adolescents have always been a topic of interest because of the effects they could have on the individual later in adulthood. Oddly enough however, the two areas of study have never been looked at in relation to one another. This study will look at different types of alone time as possible stressors in a community sample (N=82) of adolescents transitioning to college. The data on time alone and stress levels was collected through diary reports over a period of 3 days. The analysis only yielded significant effects for females and only for specific categories. It was found that females experience the lowest amount of perceived stress when they are alone and want to be alone, they have more negative affect when their desired environment differs from their current situation, and more positive affect in both the alone incongruence and not alone congruence situations. These results indicate that only women experience stress and affect changes when they encounter different congruent and incongruent environments.

Affecting over 34 million people worldwide, (0.5% of the world population) HIV/AIDS is a pandemic that is not receding its control anytime soon (Sidibe 2011). Thirty years since the chaotic emergence of fear and misunderstanding, our knowledge of the virus and its subsequent syndrome has grown exponentially, but how much of this information is really getting to the people that need it? In the corners of the Earth, where scientific knowledge rarely reaches, what can we do to stop the deadly spread of this virus? And what of the countries with a large amount of knowledge, but still a ravaging problem present in their countries? When this information is disseminated- sometimes a matter of ‘if’ in certain countries, it is primarily through unreliable sources, most of the countries examined through the media, which has a tendency to skew and misinterpret information-specially scientific. This is the information that enters the lives of people in several different countries, for example, the United States, France, China, Brazil, Uganda, and South Africa: Misunderstandings of how to protect themselves from the virus, and its effects on the body. These misunderstandings have led to millions of lives lost as myths such as showering to cure AIDS and that AIDS only infect the ‘sinners’ continue to surface throughout the globe. The Public Health threat is due to knowledge deficits, and incorrect perceived ‘knowledge’ and ‘awareness of the problem’. Here, in a six-country analysis of common misconceptions and the subsequent policies and prevalence rate, it has begun to be clear that the hardest hit areas are those with the most stigma, the most misguided policies, the most uninformed leadership, and because of this, the most mislead citizens. The biological misunderstandings of HIV/AIDS are at the root of the public health threat continuing to keep its hold in the modern world, 30 years after its documented outbreak.

Description
This study was conducted as part of an underlying initiative to elucidate the mechanism of action of natural antibacterial clay minerals for application as therapeutic agents for difficult-to-treat infections such as methicillin-resistant Staphylococcus aureus (MRSA)-derived skin lesions and Buruli ulcer. The goal of this investigation was to determine whether exposure to the leachate of an antibacterial clay mineral, designated as CB, produced DNA double-strand breaks (DSBs) in Escherichia coli. A neutral comet assay for bacterial cells was adapted to assess DSB levels upon exposure to soluble antimicrobial compounds. Challenges involved with the adaptation process included comet visualization and data collection. To appropriately account for antimicrobial-mediated strand fragmentation, suitable control reactions comprised of exposures to water, ethanol, kanamycin, and bleomycin were developed and optimized for the assay. Bacterial exposure to CB resulted in significantly longer comet lengths compared to negative control exposures, suggesting that CB killing activity involves the induction of DNA DSBs. The results of this investigation further characterize the antimicrobial mechanisms associated with a particular clay mineral mixture. The adapted comet assay protocol described herein functions as an effective tool to assess double-strand fragmentation resulting from exposure to soluble antimicrobial compounds and to visually compare results from experimental and control reactions.
