The Perceived Benefits Of And Barriers To Open-Water Swimming: A Mixed-Methods Examination, David Elliott Ph.D, Mark A. Christie Ph.D

International Journal of Aquatic Research and Education

This study set out to determine the perceived benefits of, and barriers to, open-water swimming (OWS). Adopting a mixed-methods approach, six hundred and sixty-five open-water swimmers responded to an online survey consisting of the Exercise Benefits and Barriers Scale (EBBS) and a series of open-ended questions. Data from the EBBS revealed the strongest perceived benefits to be ‘Psychological Outlook’ and ‘Life Enhancement.’ In terms of barriers, those presented in the EBBS received low ratings with only ‘Physical Exertion’ considered as being somewhat problematic. Content analysis performed on the open-ended responses showed social aspects, mental well-being, and connection to nature as …

Evaluation Of Online Information On The Cold Shock Response To Accidental Immersion In Cold Water, Adam Wilson, Heather Massey, Clare M. Eglin

PURPOSE: Prior evidence suggests a progression-free survival (PFS) benefit from adding metastasis-directed therapy (MDT) to standard-of-care (SOC) systemic therapy for patients with some oligometastatic solid tumors. Randomized trials testing this hypothesis in breast cancer have yet to be published. We sought to determine whether adding MDT to SOC systemic therapy improves PFS in oligometastatic breast cancer.

METHODS AND MATERIALS: External Beam Radiation to Eliminate Nominal Metastatic Disease is a multicenter phase 2 randomized basket trial testing the addition of MDT to SOC systemic therapy in patients with ≤5 metastases (NCT03599765). Patients were randomly assigned 1:1 to MDT (definitive local treatment …

Although treatment with standard frontline therapies, including a FLT3 inhibitor (FLT3i) reduces AML burden and achieves clinical remissions, most patients with AML with FLT3 mutation relapse due to therapy-resistant stem/progenitor cells. The core ATPases, BRG1 (SMARCA4) and BRM (SMARCA2) of the canonical (c) BAF (BRG1/BRM-associated factor) complex is a dependency in AML cells, including those harboring FLT3 mutations. We have previously reported that treatment with FHD-286, a BRG1/BRM ATPases inhibitor, induces differentiation and loss of viability of AML stem/progenitor cells. Findings of present studies demonstrate that treatment with FHD-286 induces lethality in AML cells, regardless of sensitivity or resistance to …

Effects Of Social Isolation On Locus Coeruleus Opioid Receptor Expression And Affective Behavior, John Tkaczynski, Jordan Riser, Maya Patel, Nicole Shellenbarger, Jin Park, Daniel Manvich, Daniel J Chandler

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Social isolation is a stressor that impairs homeostatic neuroendocrine functions and is associated with the development of several mood disorders characterized by persistent negative affect. Persistent feelings of loneliness have been growing public health concerns for several years and were greatly exacerbated by the onset of the COVID-19 pandemic. The problem has grown so severe the U.S. Surgeon General recently declared loneliness to be an epidemic health concern that is associated with poor mental and somatic health outcomes. Therefore, identifying mechanisms of neuroadaptation that contribute to the development of persistent negative affect is a critical step in the identifying better …

BACKGROUND: Scalable identification of patients with post-acute sequelae of COVID-19 (PASC) is challenging due to a lack of reproducible precision phenotyping algorithms, which has led to suboptimal accuracy, demographic biases, and underestimation of the PASC.

METHODS: In a retrospective case-control study, we developed a precision phenotyping algorithm for identifying cohorts of patients with PASC. We used longitudinal electronic health records data from over 295,000 patients from 14 hospitals and 20 community health centers in Massachusetts. The algorithm employs an attention mechanism to simultaneously exclude sequelae that prior conditions can explain and include infection-associated chronic conditions. We performed independent chart reviews …

Strategies To Improve Antibody-Mediated Protection Against Herpes Simplex Virus Infections, Matthew D. Slein

Dartmouth College Ph.D Dissertations

No efficacious vaccine exists for herpes simplex virus and the global burden of disease remains high. Antibodies can serve as potent therapeutics to protect high risk populations such as neonates. Although rare, neonatal HSV (nHSV) infections can result in significant mortality and lifelong neurological morbidity even with antiviral therapy. While HSV-specific maternally derived antibodies significantly reduce the risk of neonatal disease in humans, the mechanisms by which they mediate protection have yet to be described. Using a mouse model of neonatal HSV (nHSV) infections we aimed to determine the mechanisms of antibody-mediated protection using monoclonal antibodies (mAbs) targeting two of …

In the developing mammalian heart, the endocardium and the myocardium are separated by so-called cardiac jelly. Communication between the endocardium and the myocardium is essential for cardiac morphogenesis. How membrane-localized receptors and ligands achieve interaction across the cardiac jelly is not understood. Working in developing mouse cardiac morphogenesis models, we used a variety of cellular, imaging, and genetic approaches to elucidate this question. We found that myocardium and endocardium interacted directly through microstructures termed tunneling nanotube-like structures (TNTLs). TNTLs extended from cardiomyocytes (CMs) to contact endocardial cells (ECs) directly. TNTLs transported cytoplasmic proteins, transduced signals between CMs and ECs, and …

Cranial Radiation Disrupts Dopaminergic Signaling And Connectivity In The Mammalian Brain, Die Zhang, Riya Thomas, Thanh Thai Lam, Ines Veselinovic, David R Grosshans

Faculty, Staff and Student Publications

Cognitive impairment is a common and challenging side effect of cranial radiation therapy for brain tumors, though its precise mechanisms remain unclear. The mesocortical dopaminergic pathway, known to play a key role in cognitive function, is implicated in several neuropsychiatric disorders, yet its involvement in radiation-induced cognitive dysfunction is unexplored. Here, with using in vivo multi-electrode array recordings of both anesthetized and free-moving rats to monitor the firing activities of dopamine neurons in the ventral tegmental area (VTA) and local field potentials in both the prefrontal cortex (PFC) and VTA, as well as the immunofluorescence assays and western blotting, we …

Control Of Clostridioides Difficile Virulence And Physiology By The Flagellin Homeostasis Checkpoint Flic-Fliw-Csra In The Absence Of Motility, Duolong Zhu, Katherine J Wozniak, Firas Midani, Shaohui Wang, Xingmin Sun, Robert A Britton

Faculty, Staff and Students Publications

Mutations affecting Clostridioides difficile flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving fliC, fliW, and csrA, which creates a feedback system to regulate flagella production. Through genomic analysis of C. difficile clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene fliC and regulatory gene fliW. We therefore investigated the roles of fliC, fliW …

The continued emergence of antimalarial drug resistance highlights the need to develop new antimalarial therapies. Unfortunately, new drug development is often hampered by undesirable drug-like properties of lead compounds. Prodrug approaches temporarily mask undesirable compound features, improving bioavailability and target penetration. We have found that lipophilic diester prodrugs of phosphonic acid antibiotics, such as fosmidomycin (Fsm), exhibit significantly higher antimalarial potency than their parent compounds [R.L. Edwards et al., Sci. Rep. 7, 8400 (2017)]. However, the activating enzymes for these prodrugs were unknown. Here, we show that an erythrocyte enzyme, acylpeptide hydrolase (APEH), is the major activating enzyme of multiple …

Structural Basis For Intrinsic Strand Displacement Activity Of Mitochondrial Dna Polymerase, Ashok Nayak, Viktoriia Sokolova, Sirelin Sillamaa, Karl Herbine, Juhan Sedman, Dmitry Temiakov

Department of Biochemistry and Molecular Biology Faculty Papers

Members of the Pol A family of DNA polymerases, found across all domains of life, utilize various strategies for DNA strand separation during replication. In higher eukaryotes, mitochondrial DNA polymerase γ relies on the replicative helicase TWINKLE, whereas the yeast ortholog, Mip1, can unwind DNA independently. Using Mip1 as a model, we present a series of high-resolution cryo-EM structures that capture the process of DNA strand displacement. Our data reveal previously unidentified structural elements that facilitate the unwinding of the downstream DNA duplex. Yeast cells harboring Mip1 variants defective in strand displacement exhibit impaired oxidative phosphorylation and loss of mtDNA, …

Alpha-Frequency Stimulation Strengthens Coupling Between Temporal Fluctuations In Alpha Oscillation Power And Default Mode Network Connectivity, Yijia Ma, Joshua A Brown, Chaowen Chen, Mingzhou Ding, Wei Wu, Wen Li

Faculty, Staff and Student Publications

Alpha (8–12 Hz) oscillations and default mode network (DMN) activity dominate the brain's intrinsic activity in the temporal and spatial domains, respectively. They are thought to play crucial roles in the spatiotemporal organization of the complex brain system. Relatedly, both have been implicated, often concurrently, in diverse neuropsychiatric disorders, with accruing electroencephalogram (EEG)/magnetoencephalogram and functional magnetic resonance imaging (fMRI) data linking these two neural activities both at rest and during key cognitive operations. Prominent theories and extant findings thus converge to suggest a mechanistic relationship between alpha oscillations and the DMN. Here, we leveraged simultaneous EEG–fMRI data acquired before and …

Myelodysplastic syndromes/neoplasms (MDSs) are heterogeneous stem cell malignancies characterized by poor prognosis and no curative therapies outside of allogeneic hematopoietic stem cell transplantation. Despite some recent approvals by the US Food and Drug Administration, (eg, luspatercept, ivosidenib, decitabine/cedazuridine, and imetelstat), there has been little progress in the development of truly transformative therapies for the treatment of patients with MDS. Challenges to advancing drug development in MDS are multifold but may be grouped into specific categories, including criteria for risk stratification and eligibility, response definitions, time-to-event end points, transfusion end points, functional assessments, and biomarker development. Strategies to address these challenges …

The cholesterol biosynthesis pathway is upregulated during breast cancer development and progression. Inhibition of the aberrantly upregulated cholesterol pathway by statins reduces breast tumor incidence and burden by 50% in SV40 C3(1) TAg mice, a mouse model of triple negative breast cancer. We hypothesized that fluvastatin's preventive efficacy could be further enhanced by co-targeting the statin-induced restorative feedback pathways that tightly control the cholesterol pathway and are involved in resistance to statins. Acyl-coenzyme A: cholesterol acyltransferase (

Confounding Factors Of Cervical Carcinogenesis And Cervical Cancer Health Disparity, Vivek Kumar Kashyap, Namita Sinha, Nadeem Zafar, Murali M. Yallapu, Santosh Kumar, Everardo Cobos, Subhash C. Chauhan

Research Symposium

Clinical studies show that cervical cancer is the most frequently detected cancer in women living with human immunodeficiency virus (HIV), which has been defined as an acquired immunodeficiency syndrome (AIDS). Women living with HIV are 6 times more likely to develop cervical cancer compared to the general population, and an estimated 5% of all cervical cancer cases are attributable to HIV. Studies suggest that several genes are involved in different molecular pathways, which can influence the vulnerability, severity, or advancement of cervical cancer in the presence of HIV and human papillomavirus (HPV) co-infection. Clinical studies have also shown levels of …
