Teaching Qualitative Research Methods In Media And Communication: The Benefits And Limitations Of Digital Learning Objects, Delia Dumitrica, Paulina Jarmula

The Qualitative Report

Teaching qualitative research is often hampered by student uncertainties around how to apply methodological knowledge in practice. Digital learning objects (DLOs) may offer a solution to this problem, although they also come with limitations. This study assessed the student perspective on the strengths and limitations of six qualitative analysis DLOs in the field of media and communication. Drawing from a thematic analysis of 527 written student reflections on the use of these DLOs in learning practices, this paper found that DLOs were helpful in clearing doubts and cementing knowledge. Furthermore, they motivated students by increasing self-regulation and by providing a …

Analysis Of The Cytopathogenic Effect Of Different Hiv-1 Vpr Isoforms On Primary Human Cd4+ T Cells And A Model Cell Line, Jonatan Josue Fierro Nieves

Theses and Dissertations

Human Immunodeficiency Virus (HIV) is the causal agent of acquired immunodeficiency syndrome (AIDS), a disease characterized by the depletion of CD4+ T cells which impairs immune response. Analysis of HIV-1 infected patients has identified two distinctive phenotypes that differ in length of time towards the development of AIDS, Rapid Progressor (RP) and Long-Term Non-Progressor (LTNP) patients. The cause of the differences between these two groups is a process that is still under investigation. Hints about a possible cause have been attributed to the discovery of mutations in the viral protein R (Vpr) that have been associated with these phenotypes: mutations …

Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering survivorship), and northern limits (unable to survive winter). Our model indicates H. zea population dynamics are hierarchically structured with continental-level effects that …

The Matricellular Protein Sparc Induces Inflammatory Interferon-Response In Macrophages During Aging, Seungjin Ryu, Sviatoslav Sidorov, Eric Ravussin, Maxim Artyomov, Akiko Iwasaki, Andrew Wang, Vishwa Deep Dixit

Clinical Research Faculty Publications

The risk of chronic diseases caused by aging is reduced by caloric restriction (CR)-induced immunometabolic adaptation. Here, we found that the matricellular protein, secreted protein acidic and rich in cysteine (SPARC), was inhibited by 2 years of 14% sustained CR in humans and elevated by obesity. SPARC converted anti-inflammatory macrophages into a pro-inflammatory phenotype with induction of interferon-stimulated gene (ISG) expression via the transcription factors IRF3/7. Mechanistically, SPARC-induced ISGs were dependent on toll-like receptor-4 (TLR4)-mediated TBK1, IRF3, IFN-β, and STAT1 signaling without engaging the Myd88 pathway. Metabolically, SPARC dampened mitochondrial respiration, and inhibition of glycolysis abrogated ISG induction by SPARC …

Meditation Program For First Year Medical Undergraduate Students: A Feasibility Study, Anumeha Bhagat, Anita Sinha Malhotra, Ajeet Kumar Sidana

Journal of Wellness

Introduction: Prevalence of stress among Indian medical undergraduate students is currently higher than the global stress level. Notably, although India is considered home to yogic practices, attempts at incorporating them in the daily routines of medical students have been lacking. In Raj Yoga Meditation (RYM), the steps for meditation are clear and explicit, so it is easy to practice. The study aimed to assess the feasibility of daily practice of RYM by medical undergraduates and find out if there is an improvement in the mental health and stress levels of the participants.

Methods: We chose 80 students randomly from two …

HEALTHCARE UTILIZATION OF U.S. HEALTHCARE SYSTEM

BY

Kweku J. Agyeman

Background and Purpose of the Study: Healthcare access and utilization in the U.S. continue to pose serious challenges to immigrants. Although the U.S. spends the most on healthcare ($3.8 trillion) among developed countries, accessing and utilizing the U.S. healthcare has become an illusion to most immigrants living in the U.S. including Ghanaians. To date, little is known specifically about Ghanaian immigrants’ access and utilization of the U.S. Healthcare system. For Ghanaians and other immigrants to fully understand the complex U.S. Healthcare …

Ag-Iot For Crop And Environment Monitoring: Past, Present, And Future, Nipuna Chamara, Md Didarul Islam, Geng Bai, Yeyin Shi, Yufeng Ge

Department of Agricultural and Biological Systems Engineering: Faculty Publications

CONTEXT: Automated monitoring of the soil-plant-atmospheric continuum at a high spatiotemporal resolution is a key to transform the labor-intensive, experience-based decision making to an automatic, data-driven approach in agricultural production. Growers could make better management decisions by leveraging the real-time field data while researchers could utilize these data to answer key scientific questions. Traditionally, data collection in agricultural fields, which largely relies on human labor, can only generate limited numbers of data points with low resolution and accuracy. During the last two decades, crop monitoring has drastically evolved with the advancement of modern sensing technologies. Most importantly, the introduction …

Carbohydrate Utilization By The Gut Microbiome Determines Host Health Responsiveness To Whole Grain Type And Processing Methods, Caroline Smith, Mallory J. Suhr Van Haute, Yibo Xian, Rafael R. Segura Munoz, Sujun Liu, Robert J. Schmaltz, Amanda E. Ramer-Tait, Devin J. Rose

Department of Food Science and Technology: Faculty Publications

Little is known about how interactions among grain processing, grain type, and carbohydrate utilization (CU) by the microbiome influence the health benefits of whole grains. Therefore, two whole grains – brown rice and whole wheat – and two processing methods – boiling (porridge) and extrusion – were studied for their effects on host metabolic outcomes in mice harboring human microbiomes previously shown in vitro to have high or low CU. Mice carrying either microbiome experienced increases in body weight and glycemia when consuming Western diets supplemented with extruded grains versus porridge. However, mice with the high but not low CU …

Food-Borne Chemical Carcinogens And The Evidence For Human Cancer Risk, Tetyana Kobets, Benjamin P C Smith, Gary M Williams

NYMC Faculty Publications

Commonly consumed foods and beverages can contain chemicals with reported carcinogenic activity in rodent models. Moreover, exposures to some of these substances have been associated with increased cancer risks in humans. Food-borne carcinogens span a range of chemical classes and can arise from natural or anthropogenic sources, as well as form endogenously. Important considerations include the mechanism(s) of action (MoA), their relevance to human biology, and the level of exposure in diet. The MoAs of carcinogens have been classified as either DNA-reactive (genotoxic), involving covalent reaction with nuclear DNA, or epigenetic, involving molecular and cellular effects other than DNA reactivity. …

Bet Inhibition Induces Vulnerability To Mcl1 Targeting Through Upregulation Of Fatty Acid Synthesis Pathway In Breast Cancer, Gonghong Yan, Augustin Luna, Heping Wang, Behnaz Bozorgui, Xubin Li, Maga Sanchez, Zeynep Dereli, Nermin Kahraman, Goknur Kara, Xiaohua Chen, Caishang Zheng, Daniel Mcgrail, Nidhi Sahni, Yiling Lu, Ozgun Babur, Murat Cokol, Bora Lim, Bulent Ozpolat, Chris Sander, Gordon B Mills, Anil Korkut

Faculty, Staff and Student Publications

Therapeutic options for treatment of basal-like breast cancers remain limited. Here, we demonstrate that bromodomain and extra-terminal (BET) inhibition induces an adaptive response leading to MCL1 protein-driven evasion of apoptosis in breast cancer cells. Consequently, co-targeting MCL1 and BET is highly synergistic in breast cancer models. The mechanism of adaptive response to BET inhibition involves the upregulation of lipid synthesis enzymes including the rate-limiting stearoyl-coenzyme A (CoA) desaturase. Changes in lipid synthesis pathway are associated with increases in cell motility and membrane fluidity as well as re-localization and activation of HER2/EGFR. In turn, the HER2/EGFR signaling results in the accumulation …

Reduction Of Protein Levels In Broiler Feed For Commercial Application – A German Case, Andreas Lemme, Kilian Fenske, Heiner Westendarp, Mathias Guhe, Elmar Rother

Proceedings of the Arkansas Nutrition Conference

A project was initiated to apply dietary CP reduction under commercial conditions. The main objective was to demonstrate and validate that dietary CP can be reduced without compromising broiler performance in a production system which is already rather efficient. In addition, we wanted to demonstrate the potential of dietary CP reduction on reducing N-excretions especially in the context of German revised regulations and monitoring attempts. Finally, as previous research suggested, few further aspects such as impact of dietary CP reduction on litter quality and quantity, footpad health, change of ingredient inclusion levels and related impact on sustainability impact factors were …

Application Of Simulation Modelling In Broiler Integration: Is It A Necessary Nutritional Tool?, Peter Chrystal

Proceedings of the Arkansas Nutrition Conference

Modelling techniques have been used in many industries globally to illustrate to others an understanding of the way processes work. Also, engineers and scientists employ models to predict the consequences of various courses of action. Simple pictorial models, such as the diagram of the chicken digestive system, are useful in education and may be more suitable than a photograph for the purposes of explaining how the animal converts ingested feed into components that can be assimilated, leaving residue that is excreted. Complex, predictive models seek to quantify a specified outcome based on defined inputs. Many attempts have been made over …

State Of The Art Pullet And Breeder Nutrition, Rick Van Emous

Proceedings of the Arkansas Nutrition Conference

During the last six to seven decades, broilers have been successfully selected for maximum growth and feed efficiency (Zuidhof et al., 2014). Modern fast-growing broilers reach a body weight of 2.0 to 2.5 kg in 35 to 45 days with an average daily growth of 55 or more gram a day (Augère-Granier, 2019). In a study with different broiler strains representative of broilers in 1957 or 1978 were compared with a broiler strain from 2005 (Zuidhof et al., 2014). The 2005 strain showed, over a 56-day growth period, a 4.6 times higher growth rate and a 50% lower feed conversion …

Broiler Breeder Males: Feed And Nutrition Discussion, Benton Hudson

Proceedings of the Arkansas Nutrition Conference

The methods for feeding broiler breeder males have evolved over recent decades, and further revisions will likely be needed as males become more challenging to manage. Since the introduction of separate male feeding systems in the early 1980’s, breeder males’ nutrient needs have been better managed via daily feed restriction. If a breeder operation can effectively produce, haul, and store a separate male diet, then it provides more options to use different nutrient levels or feed additives that are designed to enhance fertility. This article will outline the history of male-separate feeding and revisit nutritional research on fertility of broiler …

Amino Acids Were Not All Created Equal, Peter H. Selle, Shemil P. Macelline, Peter V. Chrystal, Sonia Y. Liu

Proceedings of the Arkansas Nutrition Conference

The contention that amino acids were not all created equal is based on the simple premise that intestinal uptakes of non-bound (synthetic, crystalline, feed-grade) amino acids are more rapid than their protein-bound counterparts. The post-enteral ramifications of this difference in bioequivalence are amplified in broiler chickens given their express growth rates and just one complication is the post-prandial oxidation of amino acids. The lack of bioequivalence between non-bound and protein-bound amino acids is a real obstacle to the development and adoption of reduced-crude protein diets that have the potential to promote sustainable chicken-meat production Thus, the purpose of this paper …

Recent Advancements On Calcium And Phosphorus Recommendations In Broilers, Justina Caldas, Marcelo Silva

Proceedings of the Arkansas Nutrition Conference

Calcium and phosphorus have been recognized essential nutrients in chickens since 1950’s (Lesson & Summers, 2001) playing important roles in bone development, among other functions. Calcium is assumed an inexpensive nutrient in animal least cost formulation while phosphorus is considered expensive and scant. The actual economic impact comes from the influence of calcium on phosphorus requirements, changes in phosphorus digestibility, buffer capacity, gut health, trace mineral absorption, fat digestibility, welfare traits, etc. Both minerals have important interactions to be considered during formulation. Few changes have been made over the past 20 years to calcium and phosphorus recommendations because these values …

Decoding The Gut Microbiome; Providing Solutions For Poultry Production, Nichoals Evans, Peter Karnezos, Curtis Novak, Diana Ayala, Emily Kimminau, Kay Russo

Proceedings of the Arkansas Nutrition Conference

The term “microbiome” refers to all the micro-organisms within a particular environment. In poultry, the microbiome is influenced by the barn, diet, and age of the birds and is believed to modulate immunity and inflammation. In the past, culture methods were primarily used to evaluate the presence of the various micro-organisms present in the microbiome; however, recent technological advances in genomic sequencing have revolutionized sample analysis. This technology has opened new avenues of research in poultry production and our understanding of the associated health challenges. Turkey cellulitis has been a major economic and health concern for many years. Traditional bacterial …

Application Of Nutritional Immunology In The Mitigation Of Economic And Production Losses In The Poultry Industry Associated With Food-Borne Pathogens, Coccidiosis, And Necrotic Enteritis., Shahna Fathima, Ramesh K. Selvaraj

Proceedings of the Arkansas Nutrition Conference

Sub-therapeutic doses of antibiotics were used in poultry production since the 1950s for improved production, prophylaxis, and animal welfare. Extensive and indiscriminatory use of antibiotics led to the emergence of antibiotic resistance in food-borne pathogens of public health significance (Jones & Ricke, 2003). As per the United States Centre for Disease Control, more than 2.8 million infections in 2019 were caused by multidrug resistant bacteria. Due to public health concerns, the use of antibiotic growth promoters in livestock production was prohibited by Sweden and Denmark in 1986 and 1998 respectively (Hammerum et al., 2007). The European Union banned the use …

A Dynamic Approach To Feed Formulation, Rob Gous

Proceedings of the Arkansas Nutrition Conference

The objective of this paper is to demonstrate that the opportunity cost of using fixed tables of nutrient requirements when formulating feeds for broilers can be considerable, and that nutritionists should consider a more dynamic approach to defining the lower bounds of amino acids in particular, in line with the objective of the business, which is to maximise profit. In order to do this, it is necessary to consider the potential growth rate of the broiler, the cost of feed and amount of feed consumed, and the income generated from the sale of product.

Transitioning To Net Energy: A Swine Story, John F. Patience

Proceedings of the Arkansas Nutrition Conference

Net energy (NE) is one member of the sequence of energy systems which also includes gross energy (GE), digestible energy (DE), and metabolizable energy (ME). It is perhaps the most sophisticated because it attempts to consider more components of the ingredient or diet which normally cannot be used by the pig for maintenance and/or productive purposes. Gross energy makes no such adjustment and therefore has little direct value in diet formulation. Digestible energy corrects for energy which is lost in the feces, and metabolizable energy also adjusts for energy lost in the urine. The data in Table …

Where Can We Go With Net Energy In Poultry?, Katie Hilton

Proceedings of the Arkansas Nutrition Conference

Metabolizable energy (ME) is the main system used globally in poultry industry for feed formulation and for evaluating feed ingredients and mixed feeds (de Boer and Bickel, 1988). ME is considered a reliable index of what is available to the bird for maintenance and production but is not a predictor of how efficiently the bird uses the available energy (MacLeod, 2000). The ME system developed by Hill and Anderson (1958) was reported to provide less variation in energy values for feed and ingredients than the Fraps PE system, but MacLeod (1994, 1997, 1999) suggest that the low variation …

Limestone Solubility: What Can You Do About It?, Wenting Li, Katie Hilton, Franco Mussini, Janet Remus

Proceedings of the Arkansas Nutrition Conference

Calcium (Ca) is essential for bone development mineralisation, as well as for eggshell formation, muscle and neural functions. Depending on the type of diets (veggie vs. non-veggie), species (turkey, chicken, duck), and age of animal (young vs. adult), limestone can contribute up to 95% total Ca in the final diet, with more Ca from limestone for younger animals with veggie diet. Despite the significant contribution of limestone to total diet Ca levels, the bioavailability variation of limestone Ca is rarely considered. Phosphorus (P) is a limited resource and is the third most costly ingredient in poultry …

Visualizing Hormonal Effects On Cardiomyocyte Hypertrophic Growth Dynamics Using Digital Holographic Microscopy: Does Size Matter?, Jacquelyn Simmons

McNair Research Journal SJSU

Heart disease continues to be the leading cause of death in the United States. Humans are unable to regenerate their heart tissue following an injury. However, neonatal mice are able to regenerate their heart tissue when cardiomyocytes (CMs) proliferate. This regenerative ability is lost approximately one week after birth when proliferating mononucleated CMs become binucleated and can no longer complete the cell-cycle. Recent studies have shown the combined inhibition of thyroid hormone (T3) and norepinephrine (NE) increases CM proliferation, promotes heart regeneration, and reduces cell size in vivo. Using digital holographic microscopy, the aim of this study was to (1) …
