Autophagy And Cell Wall Integrity Pathways Coordinately Regulate The Development And Pathogenicity Through Moatg4 Phosphorylation In Magnaporthe Oryzae, Pusheng Guo, Yurong Wang, Jiayun Xu, Zhixiang Yang, Ziqi Zhang, Jinyi Qian, Jiexiong Hu, Ziyi Yin, Leiyun Yang, Muxing Liu, Xinyu Liu, Gang Li, Haifeng Zhang, Ryan Rumsey, Ping Wang, Zhengguang Zhang

School of Medicine Faculty Publications

Autophagy and Cell wall integrity (CWI) signaling are critical stress-responsive processes during fungal infection of host plants. In the rice blast fungus Magnaporthe oryzae, autophagy-related (ATG) proteins phosphorylate CWI kinases to regulate virulence; however, how autophagy interplays with CWI signaling to coordinate such regulation remains unknown. Here, we have identified the phosphorylation of ATG protein MoAtg4 as an important process in the coordination between autophagy and CWI in M. oryzae. The ATG kinase MoAtg1 phosphorylates MoAtg4 to inhibit the deconjugation and recycling of the key ATG protein MoAtg8. At the same time, MoMkk1, a core kinase of CWI, also phosphorylates …

Association Between Regulatory T Cells And Ischemic Heart Disease: A Mendelian Randomization Study, Basel Abdelazeem, Zhenya Shen

Faculty, Staff and Student Publications

BACKGROUND: An imbalance of innate and acquired immune responses is significantly involved in the pathophysiology of coronary atherosclerosis and the occurrence of ischemic heart disease (IHD). Regulatory T cells (Tregs) play an essential regulatory role in atherosclerotic plaque formation and maintenance; therefore, dysfunction of Tregs triggers the formation of atherosclerotic plaques and accelerates their progression. However, due to the inherent limitations of observational research, clinical evidence is limited concerning the relationship between the variation in peripheral Tregs and the risk of IHD, and the cause-and-effect relationship between these factors is unclear. Mendelian randomization (MR) uses genetic variation as a proxy …

Myd88 In Myofibroblasts Enhances Nonalcoholic Fatty Liver Disease-Related Hepatocarcinogenesis Via Promoting Macrophage M2 Polarization, Yu Liu, Haiqiang Chen, Xuanxuan Yan, Jie Zhang, Zhenzhong Deng, Jianchun Gu

Faculty, Staff and Student Publications

Background: Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver diseases and has emerged as the leading factor in the pathogenesis of hepatocellular carcinoma (HCC). MyD88 contributes to the development of HCC. However, the underlying mechanism by which MyD88 in myofibroblasts regulates NAFLD-associated liver cancer development remains unknown.

Results: Myofibroblast MyD88-deficient (SMAMyD88-/-) mice were protected from diet-induced obesity and developed fewer and smaller liver tumors. MyD88 deficiency in myofibroblasts attenuated macrophage M2 polarization and fat accumulation in HCC tissues. Mechanistically, MyD88 signaling in myofibroblasts enhanced CCL9 secretion, thereby promoting macrophage M2 polarization. This process may depend on …

Journal of Dietetic Education

Background: Registered Dietitian Nutritionists and other health professionals should be involved in advocacy efforts related to food access and health care. However, education about, and opportunities to actively participate in, public policy are often limited for dietetics students. The goal of this project was to identify how dietetics programs meet ACEND standards relating to public policy in their current and/or accredited program. Methods: An online survey was sent to dietetics faculty at U.S. higher education institutions. Survey questions focused on how programs currently meet ACEND standards for public policy or plan to meet standards in their dietetics program. Respondents were …

Stakeholder Perceptions Of A Hybrid Competency-Based Education Program In Dietetics, Kristen Heitman, Stephanie M. Fanelli, Jennifer A. Garner, Kristen M. Roberts, Marcia Nahikian-Nelms, Julie Kennel, Christopher A. Taylor

Journal of Dietetic Education

As requirements for entry-level dietitians advance to the master’s degree level, the Accreditation Council for Education in Nutrition and Dietetics has published a Future Education Model (FEM). At present, FEM utilizes Competency-Based Education (CBE) for optional program implementation at early adopter demonstration sites. A limited number of CBE programs exist within the field of dietetics, and there is little published literature on its use in this arena. The present study leverages focus groups with students and interviews with faculty and preceptors to evaluate use of a novel CBE program in dietetics and explore factors that facilitate or hinder implementation of …

Challenges Of Competency Management For Dietetics Program And Internship Directors: An Application Of Design Thinking, David Gaviria, Elizabeth Chen

Journal of Dietetic Education

Objective: Dietetics education transitioned to competency-based education (CBE) in July 2022. Despite its benefits, managing competencies may be a challenging aspect of CBE for dietetics program and internship directors (PDIDs), yet it is unclear what specific aspects of competency management are difficult. Using design thinking, this study sought to capture the impact recent CBE implementation had on PDIDs by identifying specific pain points (i.e., challenges) related to competency management. The results of this work serve to document such pain points and may be used to generate solutions to address or eliminate the pain points. For example, this research can support …

A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan

The Journal of Purdue Undergraduate Research

Since their discovery in the region in 2009, invasive Indonesian-native lionfish have been taking over the Belize Barrier Reef. As a result, populations of local species have dwindled as they are either eaten or outcompeted by the invaders. This has led to devastating losses ecologically and economically; massive industries in the local nations, such as fisheries and tourism, have suffered greatly. Attempting to combat this, local organizations, from nonprofits to ecotourism companies, have been manually spear-hunting them on scuba dives to cull the population. One such company, Reef Conservation Institute (ReefCI), operating out of Tom Owens Caye outside of Placencia, …

Representation Matters: Content Analysis Of Breastfeeding Images In A Commercial Stock Image Bank, Lauren M. Dinour, Melanie Shefchik

Department of Nutrition and Food Studies Scholarship and Creative Works

Several behavioral change theories posit that normative influences contribute to breastfeeding behaviors and disparities. Given that media has historically presented a narrow view of what is deemed normative in human milk feeding, this study describes who and what is represented in breastfeeding images available in a stock image bank, and whether differences exist based on the breastfeeding parent’s skin color. Using content analysis, the most relevant 2% (n = 2284) of breastfeeding and lactation images in Adobe Stock were coded for 60 variables within 12 categories, such as skin color, ability, setting, skin exposure, etc. Descriptive statistics were used …

Aspen Recovery In Northern Yellowstone: A Comment On Brice Et Al. (2021), Luke E. Painter, Robert L. Beschta, William J. Ripple

Aspen Bibliography

Aspen sapling recruitment increased as browsing by elk decreased, following the 1995–96 reintroduction of wolves in Yellowstone National Park. We address claims by Brice et al. (2021) that previous studies exaggerated recent aspen recovery. We conclude that their results actually supported previous work showing a trophic cascade benefiting aspen.

Radiofrequency Ablation Of Thyroid Nodules: A Clinical Review Of Treatment Complications, Peter P. Issa, Katherine Cironi, Leely Rezvani, Emad Kandil

School of Medicine Faculty Publications

Radiofrequency ablation (RFA) is a minimally invasive ablative modality for the treatment of thyroid nodules. Reports of RFA use have demonstrated an impressive safety profile and excellent volume reduction rates between 60-90%. Given its increased popularity in the United States as well as globally, numerous recent works have been published and a discussant of relevant complications incorporating recent insight may assist practitioners in minimizing complications and optimizing patient outcomes. Herein, we provide a comprehensive and updated review of the reported complications and side effects following RFA, summarizing their frequency and clinical presentation. We also describe a means of minimizing such …
