Climate Change and Human Responses

The Department of Anthropology’s Visiting Lecture Research Series is an ongoing edited volume compiling research products created by (under)graduate students for the Department of Anthropology’s Visiting Lecture Program at the University of Tennessee, Knoxville. Each volume in the series, compiled by its own (under)graduate student editors and approved by the Department Head, includes original research products by participating (under)graduate students. The Department of Anthropology’s Visiting Lecture Program, also known as Current Trends in Anthropology (ANTH357/550), is a symposium held annually each fall semester with a different theme for the purpose of exposing students to anthropologists from around the world and their relevant research. Led by Dr. David Anderson, the main theme of the Department of Anthropology’s Lecture Program in the fall of 2020 was Climate Change and Human Response. Presentations from visiting researchers covered a wide variety of anthropologically influenced work that touched upon the following subthemes: Global Climate and Environmental Change, and Human response Social Inequality and Access to Resources (i.e., water, oil, agricultural and marine resources) Human Demographic Change Migration and Relocation (i.e., due to conflict, resource scarcity, climate change, repression) Structural Violence, Warfare, and Genocide Participating (under)graduate students took inspiration from these visiting lectures, and the underlying subthemes for the series, and created relevant research products that ranged from research papers and visual presentations to creative fictional short stories, podcasts, and mixed media art installations. All students were invited to submit their research products for inclusion in the inaugural volume for The Department of Anthropology’s Visiting Lecture Research Series. Contents 1.

TEXAS AGRICULTURE BY CONGRESSIONAL DISTRICT: 1993-1996

Texas Agriculture by Congressional Districts: 1993-96 is an update of previous editions of this publication. Commodity sales by county are estimates made by county agents and, therefore, are not official. In all but 4 of 30 Texas congressional districts, production agriculture accounts for over $100 million in sales. In 18 of the districts, farm program commodities represent over$50 million in sales.Production Economics,

Evaluation of an Extension-Delivered Resource for Accelerating Progress in Childhood Obesity Prevention: The BEPA-Toolkit

The Balanced Energy Physical Activity Toolkit, or the BEPA-Toolkit, supports physical activity (PA) programming via Extension in elementary schools. In a pilot study, we evaluated the effectiveness of the BEPA-Toolkit as used by teachers through Supplemental Nutrition Assistance Program Education partnerships. We surveyed teachers (n = 57) regarding their use of the kit and examined associations between teacher use of the kit and objectively measured PA of students (n = 1,103). Over 80% of responders reported that the BEPA-Toolkit provided additional opportunities for PA, and children regularly exposed to the kit were more active than those having less exposure to it. The BEPA-Toolkit may support PA opportunities in underresourced school settings

The Phenotypic Effects of Royal Jelly on Wild-Type \u3cem\u3eD. melanogaster\u3c/em\u3e Are Strain-Specific

The role for royal jelly (RJ) in promoting caste differentiation of honeybee larvae into queens rather than workers is well characterized. A recent study demonstrated that this poorly understood complex nutrition drives strikingly similar phenotypic effects in Drosophila melanogaster, such as increased body size and reduced developmental time, making possible the use of D. melanogaster as a model system for the genetic analysis of the cellular mechanisms underlying RJ and caste differentiation. We demonstrate here that RJ increases the body size of some wild-type strains of D. melanogaster but not others, and report significant delays in developmental time in all flies reared on RJ. These findings suggest that cryptic genetic variation may be a factor in the D. melanogaster response to RJ, and should be considered when attempting to elucidate response mechanisms to environmental changes in non-honeybee species

Effects of Co-ingesting Dietary Nitrate and Vitamin C on Nitric Oxide Bioavailability, Blood Pressure, and Cardiovascular Reactivity in Hispanic Females

High blood pressure is a hallmark of chronic disease and is disproportionately prevalent in ethnic minorities. Dietary nitrate has been shown to lower blood pressure via increased nitric oxide (NO), but few studies have examined if combining nitrate with vitamin C (VITC) could have beneficial synergistic effects on blood pressure by augmenting NO, and limited data exist in females. PURPOSE: To investigate if combining nitrate-rich beetroot juice (BR) with VITC could further augment NO bioavailability and improve blood pressure in Hispanic females compared to BR and VITC ingested alone. METHODS: Eight sedentary Hispanic females participated in four conditions to ingest: 1) BR and VITC (BR+VITC), 2) BR and crystal light (BR+CRY), 3) nitrate-depleted BR and VITC (PL+VITC), and 4) PL and CRY (PL+CRY). A blood draw and blood pressure were obtained at rest, followed by a cardiovascular reactivity test. RESULTS: Plasma nitrate was increased in BR+VITC and BR+CRY compared to PL+VITC and PL+CRY (P0.05). Plasma nitrite was increased in BR+VITC and BR+CRY compared to PL+VITC and PL+CRY (P0.05). CONCLUSION: Co-ingestion of dietary nitrate and VITC increased plasma nitrite compared to BR alone, which could indicate augmented NO bioavailability following BR+VITC; however, there was no impact of nitrate supplementation on markers of cardiovascular health

Diminished physical function in older HIV-infected adults in the Southeastern U.S. despite successful antiretroviral therapy

As antiretroviral therapy efficacy improves, HIV is gradually being recognized more as a chronic disease within the aging HIV-infected population. While these individuals are surviving into old age, they may, however, be experiencing “accelerated aging” with greater declines in physical function than that observed among comparably matched individuals free of HIV. This decline is not well understood and it remains unclear if physical decline correlates with the degree of immunosuppression based on CD4 lymphocyte nadir

The influence of a family program on adolescent tobacco and alcohol use

Objectives. This study examined a family-directed program's effectiveness in preventing adolescent tobacco and alcohol use in a general population. Methods. Adolescents aged 12 to 14 years and their families were identified by random-digit dialing throughout the contiguous United States. After providing baseline data by telephone interviews, they were randomly allocated to receive or not receive a family-directed program featuring mailed booklets and telephone contacts by health educators. Follow-up telephone interviews were conducted 3 and 12 months after program completion. Results. The findings suggested that smoking onset was reduced by 16.4% at 1 year, with a 25.0% reduction for non-Hispanic Whites but no statistically significant program effect for other races/ ethnicities. There were no statistically significant program effects for smokeless tobacco or alcohol use onset. Conclusions. The family-directed program was associated with reduced smoking onset for non-Hispanic Whites, suggesting that it is worthy of further application, development, and evaluation

Nuclear Localized LSR: A Novel Regulator of Breast Cancer Behavior and Tumorigenesis

Lipolysis Stimulated Lipoprotein Receptor (LSR) has been found in the plasma membrane and is believed to function in lipoprotein endocytosis and tight junctions. Given the impact of cellular metabolism and junction signaling pathways on tumor phenotypes and patient outcome, it is important to understand how LSR cellular localization mediates its functions. We conducted localization studies, evaluated DNA binding, and examined the effects of nuclear LSR in cells, xenografts, and clinical specimens. We found LSR within the membrane, cytoplasm, and the nucleus of breast cancer cells representing multiple intrinsic subtypes. Chromatin immunoprecipitation (ChIP) showed direct binding of LSR to DNA, and sequence analysis identified putative functional motifs and post-translational modifications of the LSR protein. While neither overexpression of transcript variants, nor pharmacological manipulation of post-translational modification significantly altered localization, inhibition of nuclear export enhanced nuclear localization, suggesting a mechanism for nuclear retention. Co-immunoprecipitation and proximal ligation assays indicated LSR-pericentrin interactions, presenting potential mechanisms for nuclear-localized LSR. The clinical significance of LSR was evaluated using data from over 1,100 primary breast tumors, which showed high LSR levels in basal-like tumors and tumors from African-Americans. In tumors histosections, nuclear localization was significantly associated with poor outcomes. Finally, in vivo xenograft studies revealed that basal-like breast cancer cells that over-express LSR exhibited both membrane and nuclear localization, and developed tumors with 100% penetrance, while control cells lacking LSR developed no tumors. These results show that nuclear LSR alters gene expression and may promote aggressive cancer phenotypes
