Pasture Utilization At Islands In Northern Norway, V. Lind, Ø. Holand, F.-A. Haugen, G. Steinheim

IGC Proceedings (1977-2023)

The Norwegian sheep industry is based on utilization of “free” rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges related to e.g., loss of sheep to large carnivores make farmers think differently. The Norwegian coastline is among the longest globally and is scattered with islets and islands. Alone along the coast of Nordland county, it is estimated more than 14,000 islands. Use of islands for summer pasture is an alternative but there is a limited knowledge about such a management system. In this study, we examined lambs’ average …

The Crucial Role Of Sestrins In Oxidative Stress Response And Disease: An Analysis Of Phosphorylation Mutation S110a In Hsesn2, Julianne Fay

Honors Program: Senior Projects (Public)

Sestrins are highly conserved proteins which are induced under environmentally stressful conditions to adjust the cell’s response to such disturbances. This protein possesses two domains critical for its dual function in reducing reactive oxygen species (ROS) and regulating the mTORC1 complex. Sestrins may use diverse transcription factors, such as Nrf2, peroxiredoxin reductase activity, and a catalytic cysteine to regenerate oxidized species; however this was confirmed to be through a mechanism likely different than AhpD, for which there was distance sequence similarity. Furthermore, Sestrins are important regulators of TORC1 and AMPK, which are crucial energy sensors able to control cellular metabolism …

Noninvasive Detection, Tracking, And Characterization Of Aerogel Implants Using Diagnostic Ultrasound, Sagar Ghimire, Martina Rodriguez Sala, Swetha Chandrasekaran, Grigorios Raptopoulos, Marcus Worsley, Patrina Paraskevopoulou, Nicholas Leventis, Firouzeh Sabri

Chemistry Faculty Research & Creative Works

Medical implants are routinely tracked and monitored using different techniques, such as MRI, X‐ray, and ultrasound. Due to the need for ionizing radiation, the two former methods pose a significant risk to tissue. Ultrasound imaging, however, is non‐invasive and presents no known risk to human tissue. Aerogels are an emerging material with great potential in biomedical implants. While qualitative observation of ultrasound images by experts can already provide a lot of infor-mation about the implants and the surrounding structures, this paper describes the development and study of two simple B‐Mode image analysis techniques based on attenuation measurements and echogenicity comparisons, …

Racial, Ethnic, And Urban/Rural Differences In Transitions Into Diabetes: Evidence From The Health And Retirement Survey Biomarker And Self-Reported Data, Hyeran Chung, Mary Arends-Kuenning

Journal of Rural Social Sciences

We examine differences in transitions between stages of type 2 diabetes across racial, ethnic, and urban/rural statuses. The individual-level data from the 2006 to 2012 waves of the Health and Retirement Survey (HRS) and county-level data from the 1990-2000 U.S. Censuses, the Dartmouth Atlas of Health Care, and the Inter-university Consortium for Political and Social Research are used to analyze the transition from the stage of prediabetic to diabetic, and the transition from having no diabetes to being prediabetic and diabetic. The HRS includes both biomarker data and self- reported doctors’ diagnoses of diabetes, which allow us to identify people …

Exploring Rural-Urban Differences In Polygenic Associations For Health Among Older Adults In The United States, Trent Davidson, Jason D. Boardman, Lori M. Hunter

Journal of Rural Social Sciences

A complex combination of genes and environment influence health and, as a result, both genes and environment can play a role in shaping health disparities. We consider distinctions in these influences across rural and urban settings, expanding upon work that shows lower genetic associations in rural compared to urban places by studying an older age group and examining more than the typical outcomes of alcohol/substance abuse. Using a sample of 14,994 adults from the 1992 through 2016 waves of the Health andRetirement Study, our results suggest genetic associations for BMI and heart conditions are significantly lower in rural compared to …

Post Traumatic Growth Amongst Australian Bravery Award Recipients, Tom Voigt, Joanne Williams, Catherine M. Bennett, Angela Dew, Susan Balandin

Heroism Science

This study explored aspects of Post Traumatic Growth (PTG) amongst Australian Bravery Award recipients exposed to serious or life-threatening trauma. PTG is the process whereby some people experience growth following traumatic experiences. Previous PTG research has focused on specific disasters, incidents or cohorts of survivors. We explored a range of incidents in both civilian and non-civilian award recipients. Sixty-five Australian Bravery Award recipients (37 civilian and 28 non-civilian) completed the Post Traumatic Growth Inventory and provided additional demographic information about their bravery incident. Results showed that civilians experienced significantly higher growth (mean PTG score = 49.7 than non-civilians (mean PTG …

Participatory Evaluation Of Urochloa And Megathyrsus Forage Species In Western Kenya: Farmers Perspective, Ruth Odhiambo, Solomon Mwendia, David Mwangi, Alfred Juma, An Notenbaert

IGC Proceedings (1977-2023)

Despite western Kenya potential in dairy production, it has lagged behind compared to other regions in the country. This comes against growing per capita milk consumption in Kenya currently estimated at 120 litres per person per year. As a result, western Kenya is largely net importer of milk from neighbouring counties albeit the possibility improving productivity within. Among the most prevalent constraint to increased productivity is limited forage quality and quantity throughout the year. Napier stunting disease, which suppresses forage production from Napier grass, the most prevalent cultivated forage in western Kenya, exacerbates this. To contribute to addressing the problem, …

Microbial Population And Fermentation Characteristics Of Total Mixed Ration Prepared With Local Feed Resources In Mozambique, Y. Cai, Z. Du, S. Yamasaki, D. Nguluve, F. Macome, T. Oya

IGC Proceedings (1977-2023)

To effectively utilize locally available feed resources for dairy cattle in Africa, fermented total mixed ration (TMR) was prepared using Napier grass, corn meal, wheat bran, formula feed, and mineral and vitamin mix. The fermentation quality of TMR were analyzed after 14 days of ensiling. Before ensiling, aerobic bacteria were the dominant bacteria, after ensiling, lactic acid bacteria counts increased rapidly and became the dominant bacteria in TMR. After 14 days of ensiling, aerobic bacteria, coliform bacteria, yeasts, and molds showed lower (P < 0.05) counts in TMR than those before ensiling. The dry matter (DM) of TMR was adjusted to 45.50%, their crude protein and neutral detergent fiber contents were approximately 11.48, and 55.25% of DM, respectively. After 14 days of ensiling, TMR fermented to a good quality, the pH was reduced to 3.90; the lactic acid and ammonia nitrogen contents were 1.01 and 0.31% of FM, respectively; the propionic acid and butyric acid were too low to detect. The results confirm that fermented TMR prepared with local feed resources can attain a good quality in Africa.

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh

Publications and Research

Background

Heterochrony, change in the rate or timing of development, is thought to be one of the main drivers of morphological evolution, and allometry, trait scaling patterns imposed by size, is traditionally thought to represent an evolutionary constraint. However, recent studies suggest that the ontogenetic allometric trajectories describing how organisms change as they grow may be labile and adaptive. Here we investigated the role of postnatal ontogenetic development in the morphological diversification of Paleoanguimorpha, the monitor lizards and allies, a clade with extreme body size disparity. We obtained linear and geometric morphometric data for more than 1,600 specimens belonging to …

Evidence For The Oxidation Of Earth’S Crust From The Evolution Of Manganese Minerals, Daniel R. Hummer, Joshua J. Golden, Grethe Hystad, Robert T. Downs, Ahmed Eleish, Chao Liu, Jolyon Ralph, Shaunna M. Morrison, Michael B. Meyer, Robert M. Hazen

Publications

Analysis of manganese mineral occurrences and valence states demonstrate oxidation of Earth’s crust through time. Changes in crustal redox state are critical to Earth’s evolution, but few methods exist for evaluating spatially averaged crustal redox state through time. Manganese (Mn) is a redox-sensitive metal whose variable oxidation states and abundance in crustal minerals make it a useful tracer of crustal oxidation. We find that the average oxidation state of crustal Mn occurrences has risen in the last 1 billion years in response to atmospheric oxygenation following a 66 ± 1 million-year time lag. We interpret this lag as the average …

The Triple Linguistic Heritage In Tanzania: Opportunities And Challenges

Journal of Humanities and Social Sciences

Colonial history exposes Tanzania to triple linguistic heritage, that has at times plunged the nation into linguistic confusion. This heritage involves Kiswahili, ethnic community languages (ECLs) and English. Whereas each of the languages has been limited to some use through policies, some of the languages have pushed their own way, often breaking policy boundaries. It is shown in this paper that, firstly, the exclusion of ECLs by post independence policies has denied the nation important socio-cultural and economic avenues that could foster rapid social and economic development. Secondly, policies have not succeeded to strictly confine the three languages to some …

The Aoc In The Age Of Covid—Pandemic Preparedness Planning In The Federal Courts, Zoe Niesel

St. Mary's Law Journal

The 2020 COVID-19 pandemic created a crisis for American society—and the federal courts were not exempt. Court facilities came to a grinding halt, cases were postponed, and judiciary employees adopted work-from-home practices. Having court operations impacted by a pandemic was not a new phenomenon, but the size, scope, and technological lift of the COVID-19 pandemic was certainly unique.

Against this background, this Article examines the history and future of pandemic preparedness planning in the federal court system and seeks to capture some of the lessons learned from initial federal court transitions to pandemic operations in 2020. The Article begins by …

Characterization Of Testis-Derived Mesenchymal Cells And The Hunt For Universal Stemness Markers, Myret Ghabriel

Theses and Dissertations

Mesenchymal stromal/stem cells (MSCs) are multipotent cells residing in multiple tissues with the capacity for self-renewal and differentiation into various cell types. Due to the myriad sources of MSCs the International Society for Cellular Therapy (ISCT) proposed certain criteria for their characterization. Here, we isolate adult MSCs from mouse testes and demonstrate that these testis-derived MSCs (tMSCs) follow some of the ISCT’s criteria. tMSCs expressed the MSCs surface markers CD44, CD73, and CD29 and lacked the expression of the hematopoietic cell marker CD45. Moreover, the cells displayed the capacity for self-renewal and in vitro differentiation into adipocytes. Since the isolation …

Noncoding-Rna-Based Therapeutics With An Emphasis On Prostatic Carcinoma-Progress And Challenges., Victor E. Nava, Pin-Yu Perera, Nirbhay Kumar, Maneesh Jain

Pathology Faculty Publications

Noncoding RNAs (ncRNAs) defy the central dogma by representing a family of RNA molecules that are not translated into protein but can convey information encoded in their DNA. Elucidating the exact function of ncRNA has been a focus of discovery in the last decade and remains challenging. Nevertheless, the importance of understanding ncRNA is apparent since these molecules regulate gene expression at the transcriptional and post-transcriptional level exerting pleiotropic effects critical in development, oncogenesis, and immunity. NcRNAs have been referred to as "the dark matter of the nucleus", and unraveling their role in physiologic and pathologic processes will provide vast …

Caloric Restriction In Humans Reveals Immunometabolic Regulators Of Health Span, O. Spadaro, Y. Youm, I. Shchukina, S. Ryu, S. Sidorov, A. Ravussin, K. Nguyen, E. Aladyeva, A. N. Predeus, S. R. Smith, E. Ravussin, C. Galban, M. N. Artyomov, V. D. Dixit

Clinical Research Faculty Publications

The extension of life span driven by 40% caloric restriction (CR) in rodents causes trade-offs in growth, reproduction, and immune defense that make it difficult to identify therapeutically relevant CR-mimetic targets. We report that about 14% CR for 2 years in healthy humans improved thymopoiesis and was correlated with mobilization of intrathymic ectopic lipid. CR-induced transcriptional reprogramming in adipose tissue implicated pathways regulating mitochondrial bioenergetics, anti-inflammatory responses, and longevity. Expression of the gene Pla2g7 encoding platelet activating factor acetyl hydrolase (PLA2G7) is inhibited in humans undergoing CR. Deletion of Pla2g7 in mice showed decreased thymic lipoatrophy, protection against age-related inflammation, …
