A Linear Periodized Resistance Training Program Is Effective At Reducing Depressive Symptoms But Not Anxiety In Females: A Pilot, Jason Sawyer, Matthew Mcpherson, Meghan Reuter, Paul A. Cacolice

Biological and Biomedical Sciences Department Faculty Journal Articles

The purpose of this study was to determine whether a periodized resistance training program would influence self-reported depression and anxiety scores in college-aged females. Methods: Eight participants participated in a six-week periodized resistance training program. The participants completed a 3–5 repetition maximum (3–5 RM) for the sumo deadlift (SDL), bench press (BP), barbell back squat (BBS), and standing shoulder press (SSP). These data were used to estimate the 1 repetition maximum (1RM), which in turn was used to develop the periodization program. Following baseline testing, participants participated in two full-body workouts per week for six weeks. Each individual was retested …

Exploring The Role Of Cyclin D1 In Regulating Thermogenic Program In Brown Adipose Tissue, Chengrui Qiu

Biomedical Sciences ETDs

Abstract Adipose tissue plays a multifaceted role in regulating metabolic health and contributing to the pathophysiology of various diseases. Brown Adipose Tissue (BAT), a vital organ that senses different environmental cues such as cold stress and diet and then undergoes non-shivering thermogenesis in mammalian animals, enhancing energy expenditure to combat obesity. In our recent published study, we found that the mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway exhibits doubleedge effects in regulating thermogenic function, with opposite role in BAT and white adipose tissue (WAT). To further investigate the molecular mechanisms underlying the dual role of mTORC1 in thermogenic …

Increased Depressive And Anxiety Symptoms Predict Increased Severity Of Functional Impairment After Five Years: A Nationally Representative Retrospective Cohort Study, Elisabeth C. Demarco, Samantha Zocher, Blake Miyamoto, Leslie Hinyard, Divya S. Subramaniam

Journal of Patient-Centered Research and Reviews

Purpose: Performing self-care and domestic life tasks are key aspects of functional independence for older adults. While both depression and anxiety symptoms are correlated with increased functional limitation, these disorders are often studied separately, despite frequent co-occurrence and plausible interaction, and without the consideration of social health. This study examined the impact of comorbid depressive and anxiety symptoms, controlling for social participation and loneliness, on severity of functional limitation in a nationally representative sample of older adults to improve patient-centered care.

Methods: The National Social Life, Health, and Aging Project (NSHAP) Rounds 2 and 3 data were utilized. Primary outcomes …

The propensity score matching balanced baseline characteristics between the two age groups. RESULTS: After propensity score matching, 946 patients per group were analyzed. The incidence of respiratory failure (3.81% …

Measuring Operational Vs. Organizational Stress Among Rural Law Enforcement In Western Colorado, Michael Stephen Scotto

Walden Dissertations and Doctoral Studies

New research on rural law enforcement stress levels reveals concerning implications for police reform and community safety, particularly in western Colorado where officers face unique challenges. This quantitative study examined age group differences in operational and organizational stress among rural law enforcement officers using one-way ANOVAs with post-hoc Tukey's HSD tests. The study of 191 rural officers found significant differences across age groups for both operational stress (F(2, 188) = 4.08, p = .018, η2 = .042) and organizational stress (F(2, 188) = 4.15, p = .017, η2 = .043), with officers aged 24-27 experiencing the highest stress levels. Organizational …

Socially Learned Eating Pathology In African American Women (50+): A Narrative Inquiry, Patricia Ann Parker

Walden Dissertations and Doctoral Studies

This qualitative narrative study explored the lived experiences of African American women aged 50 and older who self-reported eating pathology and body image dissatisfaction. Disordered eating behaviors, including starvation, binge eating, excessive dieting, and purging, often function as maladaptive coping mechanisms for managing stress, regulating emotions, or responding to traumatic events. The study contributed to the literature by capturing detailed narratives that traced the development of disordered eating behaviors and body image dissatisfaction from early life through adulthood and across the lifespan. Grounded in Albert Bandura’s social cognitive and social learning theories and intersectionality theories, the research employed a robust …

Relapse-Free Survival Is Progressively Shortened In A Subset Of Black Patients With Immune-Mediated Ttp Treated In The Rituximab Era, Camila Masias

All Publications

Immune thrombotic thrombocytopenic purpura (iTTP) is a chronically relapsing disorder caused by autoantibody-mediated deficiency of ADAMTS13. Rituximab is frequently administered to prevent relapses, but whether the durability of rituximab effect is maintained with subsequent treatment courses has not been studied. Using the United States Thrombotic Microangiopathy Consortium (USTMA) retrospective iTTP registry, we evaluated clinical relapse-free survival (RFS) with subsequent courses of rituximab treatment in multiply relapsing patients. Separately, we evaluated overall RFS (composite of time to clinical relapse, ADAMTS13 relapse, or preemptive rituximab) in a prospective iTTP cohort from the Johns Hopkins University and the University of Minnesota. In the …

A Morphometric Signature To Identify Ductal Carcinoma In Situ With A Low Risk Of Progression, Marcelo Sobral-Leite, Simon P Castillo, Shiva Vonk, Hendrik A Messal, Xenia Melillo, Noomie Lam, Brandi De Bruijn, Yeman B Hagos, Myrna Van Den Bos, Joyce Sanders, Mathilde Almekinders, Lindy L Visser, Emma J Groen, Petra Kristel, Caner Ercan, Leyla Azarang, Jacco Van Rheenen, E Shelley Hwang, Yinyin Yuan, Renee Menezes, Esther H Lips, Jelle Wesseling

Ductal carcinoma in situ (DCIS) may progress to ipsilateral invasive breast cancer (iIBC), but often never will. Because DCIS is treated as early breast cancer, many women with harmless DCIS face overtreatment. To identify features associated with progression, we developed an artificial intelligence-based DCIS morphometric analysis pipeline (AIDmap) on hematoxylin-eosin-stained (H&E) tissue sections. We analyzed 689 digitized H&Es of pure primary DCIS of which 226 were diagnosed with subsequent iIBC and 463 were not. The distribution of 15 duct morphological measurements was summarized in 55 morphometric variables. A ridge regression classifier with cross validation predicted 5-years-free of iIBC with an …

Erk Activation Dynamics In Maturing Oocyte Controls Embryonic Nuclear Divisions In Caenorhabditis Elegans, Han Bit Baek, Debabrata Das, Shin-Yu Chen, Hongyuan Li, Swathi Arur

Faculty, Staff and Student Publications

ERK activity oscillates between sustained activation during oocyte formation and transient inactivation during oocyte maturation, fertilization, and early embryogenesis. Consequences of ectopic ERK activity upon oocyte maturation and in early embryogenesis are unknown. We show, in Caenorhabditis elegans, that ectopic ERK activity upon oocyte maturation (metaphase I oocytes) results in embryos with abnormalities in nuclear divisions leading to embryonic death. We uncover that ERK directly phosphorylates Polo-like kinase I (PLK-1), on Serine 404, to inhibit nuclear envelope breakdown (NEBD) in early embryogenesis. The RAS/ERK/PLK-1 pathway poisons zygotic NEBD and inhibits the merging of parental genomes, underlining the importance of turning …

Humination Modification: A Green Approach To Improve The Material Properties Of Scots Pine (Pinus Sylvestris L.) Sapwood, Amir Ghavidel, Arantxa Eceiza, Xinfeng Xie, Reza Hosseinpourpia

Michigan Tech Publications

Recently, wood modification with environmentally friendly modification agents has received special attention. To this end, this study was conducted to use humin fractions, in combination with citric acid (CA) and succinic acid (SA), as reaction catalysts for the modification of Scots pine (Pinus sylvestris L.) sapwood. The effects of humination modification were evaluated by means of dimensional stability, static and dynamic mechanical properties, thermal stability, crystalline structure, and biological durability tests on modified samples and compared with the unmodified reference ones. According to the results, the dimensional stability of the huminated samples significantly increased, and this increase with the presence …

Trmt1l-Catalyzed M22g27 On Tyrosine Trna Is Required For Efficient Mrna Translation And Cell Survival Under Oxidative Stress, Sseu-Pei Hwang, Han Liao, Katherine Barondeau, Xinyi Han, Cassandra Herbert, Hunter Mcconie, Amirtha Shekar, Dimitri G Pestov, Patrick A Limbach, Jeffrey T Chang, Catherine Denicourt

tRNA modifications are critical for several aspects of their functions, including decoding, folding, and stability. Using a multifaceted approach encompassing eCLIP-seq and nanopore tRNA-seq, we show that the human tRNA methyltransferase TRMT1L interacts with the component of the Rix1 ribosome biogenesis complex and binds to the 28S rRNA as well as to a subset of tRNAs. Mechanistically, we demonstrate that TRMT1L is responsible for catalyzing N2,N2-dimethylguanosine (m22G) solely at position 27 of tRNA-Tyr-GUA. Surprisingly, TRMT1L depletion also impaired the deposition of 3-(3-amino-3-carboxypropyl) uridine (acp3U) and dihydrouridine on tRNA-Tyr-GUA, Cys-GCA, and Ala-CGC. TRMT1L knockout cells have a marked decrease in tRNA-Tyr-GUA …

Robust Cluster Prediction Across Data Types Validates Association Of Sex And Therapy Response In Gbm, David L Gibbs, Gino Cioffi, Boris Aguilar, Kristin A Waite, Edward Pan, Jacob Mandel, Yoshie Umemura, Jingqin Luo, Joshua B Rubin, David Pot, Jill Barnholtz-Sloan

2020-Current year OA Pubs

BACKGROUND: Previous studies have described sex-specific patient subtyping in glioblastoma. The cluster labels associated with these "legacy data" were used to train a predictive model capable of recapitulating this clustering in contemporary contexts.

METHODS: We used robust ensemble machine learning to train a model using gene microarray data to perform multi-platform predictions including RNA-seq and potentially scRNA-seq.

RESULTS: The engineered feature set was composed of many previously reported genes that are associated with patient prognosis. Interestingly, these well-known genes formed a predictive signature only for female patients, and the application of the predictive signature to male patients produced unexpected results. …

CD226 plays a vital role in natural killer (NK) cell cytotoxicity, interacting with its ligands CD112 and CD155 to initiate immune synapse formation, primarily through leukocyte function-associated-1 (LFA-1). Our study examined the role of CD226 in NK cell surveillance of acute myeloid leukemia (AML). NK cells in patients with AML had lower expression of CD226. CRISPR-Cas9 deletion of CD226 led to reduced LFA-1 recruitment, poor synapse formation, and decreased NK cell anti-leukemic activity. Engineering NK cells to express a chimeric antigen receptor targeting the AML antigen CD38 (CAR38) could overcome the need for CD226 to establish strong immune synapses. LFA-1 …

The Golgi Complex Governs Natural Killer Cell Lytic Granule Positioning To Promote Directionality In Cytotoxicity, Luis A Pedroza, Frederique Van Den Haak, Alexander Frumovitz, Evelyn Hernandez, Everardo Hegewisch-Solloa, Tabitha K Orange, Keri B Sheehan, Susan Prockop, Aaron Bodansky, Ivan K Chinn, James R Lupski, Jennifer E Posey, Emily M Mace, Yu Li, Jordan S Orange

Cytotoxic immune cells mediate precise attacks against diseased cells to maintain organismal health. Their operational unit of killing and host defense is lytic granules (LGs), which are specialized lysosomal-related organelles. Precision in cytotoxicity is achieved by converging the many LGs to the microtubule-organizing center (MTOC) and polarizing these to the diseased cell for secretion. We identify unappreciated intimate relationships between the Golgi, MTOC, and LGs after cytotoxic cell activation, as well as the trans-Golgin protein GCC2 on the LG surface. GCC2 serves to tether LGs to the Golgi following convergence, and both GCC2 and the Golgi are required for the …

A Cnt Intercalated Co Porphyrin-Based Metal Organic Framework Catalyst For Oxygen Reduction Reaction, Pei-Pei He, Jin-Hua Shi, Xiao-Yu Li, Ming-Jie Liu, Zhou Fang, Jing He, Zhong-Jian Li, Xin-Sheng Peng, Qing-Gang He

Journal of Electrochemistry

The poor electronic conductivity of metal-organic framework (MOF) materials hinders their direct application in the field of electrocatalysis in fuel cells. Herein, we proposed a strategy of embedding carbon nanotubes (CNTs) during the growth process of MOF crystals, synthesizing a metalloporphyrin-based MOF catalyst TCPPCo-MOF-CNT with a unique CNT-intercalated MOF structure. Physical characterization revealed that the CNTs enhance the overall conductivity while retaining the original characteristics of the MOF and metalloporphyrin. Simultaneously, the insertion of CNTs generated adequate mesopores and created a hierarchical porous structure that enhances mass transfer efficiency. X-ray photoelectron spectroscopic analysis confirmed that the C atom in CNT …

Astrocytes exhibit diverse cellular and molecular properties across the central nervous system (CNS). Recent studies identified region-specific transcription factors (TF) that oversee these diverse properties; how sex differences intersect with region-specific transcriptional programs to regulate astrocyte function is unknown. Here, we show that the TF Nkx6.1 is specifically expressed in ventral astrocytes of the spinal cord and that its deletion results in sex-specific effects on astrocyte morphology. Astrocytes from males exhibit enhanced morphological complexity, accompanied by increased motor function and cholinergic synapses. In contrast, female astrocytes exhibit reduced complexity and no changes in motor function. Mechanistically, we found that Nkx6.1 …

Symptomatic pediatric participants with SMA (any type; treatment-naïve or had discontinued prior treatment) were stratified into 3 weight cohorts (≥8.5-13, >13-17, and >17-21 kg), administered onasemnogene abeparvovec, and followed for 52 weeks. Corticosteroids were initiated 24 hours before infusion with dose increases in response to adverse events (AEs) and subsequent tapering at investigator discretion. The primary objective was safety. Secondary objective was …

Indispensability Arguments And Proclus’S Deductive Proofs For Mathematical Platonism, Bridget Boczar

Acta Cogitata: An Undergraduate Journal in Philosophy

This article analyzes two types of arguments for mathematical platonism, paying close attention to the deductive argument advanced by Proclus. In the first section of the article, I lay out two arguments for mathematical platonism: a contemporary indispensability argument and Proclus’s more ancient Neoplatonic argument. The former takes an approach based on ‘inference to the best explanation’ and scientific theories, but as a result, faces serious objections. For example, scientific theories change, and because the argument is dependent on the latest scientific theories, it seems that the argument cannot give one epistemic certainty in the conclusion. The latter argument draws …

The Great Salt Lake (GSL) is the largest saline lake in the Western Hemisphere. It supports billion-dollar industries and recreational activities, and is a vital stopping point for migratory birds. However, little is known about the spatiotemporal variation of phytoplankton biomass in the lake that supports these resources. Spectral reflectance provided by three remote sensing products was compared relative to their relationship with field measurements of chlorophyll a (Chl a). The MODIS product MCD43A4 with a 500 m spatial resolution provided the best overall ability to map the daily distribution of Chl a. The imagery indicated significant spatial …

Implementation And Assessment Of A Course-Based Undergraduate Research Experience (Cure) In General Microbiology, Sheritta Fagbodun

Critical Proceedings of the STEM ED Conference (2024)

The STEM workforce is large and fast-growing. However, underrepresented minorities- URMs (African Americans, Hispanics, and Native Americans) remain poorly represented within the STEM workforce. This is partly due to the lack of retention of URMs in STEM majors. It has been shown by various studies that immersion in undergraduate research enhances the educational experience of science undergraduates and attracts and retains talented students to careers in science. However, access to undergraduate research experiences is few and often limited to high performing students. Course-based undergraduate research experiences (CUREs) engage more students in research-based learning. In this study a network-based CURE was …

Assessing The Influence Of An Eastern State's Disciplinary Alternative Education Program On Secondary Student Behavior, Alicia Michelle Gallaway

Walden Dissertations and Doctoral Studies

Services at the local disciplinary alternative education program (DAEP) include counseling and behavioral services to referred secondary students, aiming to improve their behavior. The problem addressed in this quantitative study was that a DAEP was in place in the local district since 2009, but there had been no formal assessment to determine whether differences in student discipline occurred in the semester before and the semester after students attended the DAEP. Guided by Bandura’s social cognitive theory, the purpose of this ex post facto, causal-comparative, quasi-experimental study was to investigate if there was a difference in student discipline as measured by …
