The New York State Dental Journal

Maxillofacial arteriovenous malformations (AVMs) are a rare condition in which arteries and veins are in continuity without a capillary bed in between, which poses a significant risk of severe bleeding. Intraosseous AVMs can lead to cortical bone expansion and facial deformity. Dental procedures may result in life-threatening bleeding risk if this condition is not recognized. This report describes a patient experiencing pain in the lower right side of the mouth, along with a taste of blood in the mornings and a tingling sensation in the chin and lower lip. The patient had a history of uncontrolled bleeding following a dental …

Microbial Communities Associated With Endangered West Texas Springsnails And Their Potential Roles In Conservation, Russell L. Minton, Kathryn E. Perez

School of Integrative Biological & Chemical Sciences Faculty Publications

Desert springs are one of the most threatened ecosystems globally. Those in Southwestern North America support high numbers of threatened and endemic species. Human activities present the greatest threats to springs and the organisms they support. Freshwater snails in the genera Pyrgulopsis and Tryonia are two groups of such organisms, representing diverse and threatened groups of springsnails in the Southwestern United States. Desert springs also harbour unique microbial diversity that faces similar threats from water usage and freshwater habitat degradation. Understanding springsnails and the bacteria they host represent potential exemplars for interdisciplinary conservation efforts. We studied the bacterial communities associated …

Crystal Structure And Hirshfeld-Surface Analysis Of The Pesticide Etoxazole, Chaluvarangaiah Sowbhagya, Thaluru M.Mohan Kumar, Hemmige S. Yathirajan, Sean Parkin

Chemistry Faculty Publications

Etoxazole (C21H23F2NO2), systematic name 4-(4-tert-butyl-2-ethoxyphenyl)-2- (2,6-difluorophenyl)-4,5-dihydro-1,3-oxazole, is a fluorinated insecticide and acaricide that inhibits chitin biosynthesis, disrupting insect development by preventing proper exoskeleton formation. Widely used in agriculture since 1998, it is readily absorbed by plant tissues and translocates within leaves. Metabolic studies have identified several oxidative degradation products, while toxicological assessments have examined potential effects, including oxidative stress. This study presents a detailed crystallographic and Hirshfeld surface analysis of etoxazole. The molecule consists of a central dihydro-oxazole ring flanked by 2,6-difluorophenyl and 4-tert-butyl-2-ethoxyphenyl groups, each twisted relative to the oxazole core. The dihydro-oxazole ring is nearly planar, with the …

Predicting Fatal Opioid-Involved Overdoses: A Social-Ecological Framework Matched To A Linked-Data Warehouse, Ric Bayly, Jack Cordes, Dana Bernson, Leland K Ackerson, Marc R Larochelle, Ghada H Hassan, Cici X Bauer, Thomas J Stopka

Faculty, Staff and Student Publications

Background: An estimated 60 million people used opioids non-medically worldwide in 2021. In 2019, opioid use disorder caused the loss of over 12.5 million healthy years of life due to disability and premature deaths, including those resulting from opioid-involved overdoses. Factors associated with opioid-involved overdoses are numerous, multi-layered, and interrelated. Using the social-ecological model as a foundation, we sought to comprehensively identify risk and preventive factors of fatal opioid-involved overdoses and operationalize them with quantifiable measures.

Methods: With our Community Advisory Board, investigators' expertise, and an examination of the literature, we created an expansive, opioid-overdose specific social-ecological model structured as …

Atrial fibrillation (AF) is a prevalent and morbid abnormality of the heart rhythm with a strong genetic component. Here, we meta-analyzed genome and exome sequencing data from 36 studies that included 52,416 AF cases and 277,762 controls. In burden tests of rare coding variation, we identified novel associations between AF and the genes MYBPC3, LMNA, PKP2, FAM189A2 and KDM5B. We further identified associations between AF and rare structural variants owing to deletions in CTNNA3 and duplications of GATA4. We broadly replicated our findings in independent samples from MyCode, deCODE and UK Biobank. Finally, we found that CRISPR knockout of KDM5B …

Functional Investigation Of A Putative Calcium-Binding Site Involved In The Inhibition Of Inositol 1,4, 5-Trisphosphate Receptor Activity, Vikas Arige, Larry E Wagner, Sundeep Malik, Mariah R Baker, Guizhen Fan, Irina I Serysheva, David I Yule

Faculty, Staff and Student Publications

The regulation of inositol 1,4,5-trisphosphate (IP3) receptor (IP3R) activity is thought to define the spatiotemporal patterns of Ca2+ signals necessary for the appropriate activation of downstream effectors. The binding of both IP3 and Ca2+ is obligatory for IP3R channel opening. Ca2+ however regulates IP3R activity in a biphasic manner. Ca2+ binding to a high-affinity pocket formed by the third armadillo repeat domain and linker domain promotes IP3R channel opening without altering the Ca2+ dependency for channel inactivation. These data suggest that a distinct low-affinity Ca2+-binding site is responsible for the reduction in IP3R activity at higher [Ca2+]. We mutated a …

Disrupting Tymp-Mediated Pathways To Block Lymph Node Metastasis In Ovarian Cancer, Emine Bayraktar

Dissertations and Theses (Open Access)

Historically, ovarian cancer (OC) was thought to metastasize by surface-to-surface spread, but recent developments have yielded a new understanding of the paths of metastatic spread. In epithelial ovarian cancer, the mechanisms driving lymph node (LN) metastasis are poorly understood, and it remains unclear whether omental metastasis occurs in parallel with LN metastasis. Utilizing comparative transcriptomic and proteomic profiling of primary tumors, LN metastases, and omental metastases, we identified significant upregulation of thymidine phosphorylase (TYMP) in LN metastases compared to primary and omental tumor sites. Functional studies in murine models demonstrated that TYMP silencing significantly suppressed LN metastasis, underscoring TYMP as …

Caloric Restriction And Telomere Preservation In Tert Knockout Adipocyte Progenitors Does Not Rescue Mice From Metabolic Dysfunction Due To A Tert Function In Adipocyte Mitochondria, Zhanguo Gao, Yongmei Yu, Kristin Eckel-Mahan, Mikhail G Kolonin

The Brown Foundation: Institute of Molecular Medicine

Inactivation of telomerase (TERT) in adipocyte progenitor cells (APC) expedites telomere attrition, and the onset of diabetes in mice fed high-fat diet (HFD), which promotes APC over-proliferation and replicative senescence. Here, we show that time-restricted feeding or caloric restriction in the postnatal development of mice subsequently subjected to HFD prevents telomere attrition but not glucose intolerance. This metabolic effect of dietary intervention was not observed for mice with TERT KO in endothelial or myeloid cells. To characterize the telomere-independent effects of TERT in the APC lineage, we analyzed mice with TERT knockout in mature adipocytes (AD-TERT-KO), which do not proliferate …

Modulating immune function is a critical strategy in cancer and atherosclerosis treatments. For cancer, boosting or maintaining the immune system is crucial to prevent tumor growth. However, in vascular disease, mitigating immune responses can decrease inflammation and slow atherosclerosis progression. Anti-inflammatory therapy, therefore, presents a unique dilemma for cancer survivors: while it may decrease cardiovascular risk, it might also promote cancer growth and metastasis by suppressing the immune response. Senescence presents a potentially targetable solution to this challenge; senescence increases the risk of both cancer therapy resistance and vascular disease. Exercise, notably, shows promise in delaying this premature senescence, potentially …

"Insanity" As An American Empire: The Canton Insane Asylum For American Indians, 1902-1934, Thanh Chi Nguyen

Dartmouth College Master’s Theses

This graduate thesis involves a retelling of the history of the now defunct Canton Insane Asylum, built in the early 20th century located in Canton, South Dakota. It was America’s first federal psychiatric facility dedicated exclusively for American Indians. The Canton Insane Asylum for American Indians is a touchstone whose microhistory reflects larger political and economic sentiments in both the state of South Dakota and in the United States writ large. Conceiving South Dakota, as first and foremost a white settler society erected on land forcibly wrested from American Indian people, the asylum played an important economic development role and …

Discovering Design Requirements For Next Generation Arctic Tension Fabric Shelters, Mark W. Mcveigh

Theses and Dissertations

Military operations to remote Arctic regions require large-span temporary shelters to house tactical aircraft and provide heated maintained spaces. However, the current System-50 Large Area Maintenance Shelters used by the United States Air Force and Department of Defense are inadequate for Arctic deployments. These shelters lack durability against extreme subzero temperatures, heavy snow accumulation, and high wind speeds. They also fail to address critical Arctic-specific design challenges including permafrost protection, foundation disruption caused by frost heaves, and efficient heating as a result of their inadequate thermal resistance properties. This research analyzed 20 years of climatological data from 8,399 weather observation …

Leveraging Artificial Intelligence And Machine Learning To Accelerate Discovery Of Disease-Modifying Therapies In Type 1 Diabetes., Melanie R. Shapiro, Erin M. Tallon, Matthew E. Brown, Amanda L. Posgai, Mark A. Clements, Todd M. Brusko

Manuscripts, Articles, Book Chapters and Other Papers

Progress in developing therapies for the maintenance of endogenous insulin secretion in, or the prevention of, type 1 diabetes has been hindered by limited animal models, the length and cost of clinical trials, difficulties in identifying individuals who will progress faster to a clinical diagnosis of type 1 diabetes, and heterogeneous clinical responses in intervention trials. Classic placebo-controlled intervention trials often include monotherapies, broad participant populations and extended follow-up periods focused on clinical endpoints. While this approach remains the 'gold standard' of clinical research, efforts are underway to implement new approaches harnessing the power of artificial intelligence and machine learning …

Can Oral Caffeine Decrease Postoperative Opioid Consumption Following Posterior Spinal Fusion In Adolescent Idiopathic Scoliosis? A Randomized Placebo-Controlled Trial., Anne E. Stuedemann, Richard M. Schwend, K Aaron Shaw, Nicolette Saddler, Michon Huston, Michael Benvenuti, Julia Leamon, Ashley K. Sherman, John Anderson

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Current studies have examined the efficacy of opioid-sparing analgesics primarily in adult surgical populations, while fewer guide pediatric postoperative pain treatment. Caffeine exerts most of its biological effects by binding to adenosine receptors, which are important for modifying pain and inflammation. Caffeine's ability to modulate pain following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) has not been previously assessed.

METHODS: The hospital investigational drug study (IDS) pharmacy provided either a treatment dose or placebo dose of caffeine to be given to the patient and was also in charge of randomization for the study.

RESULTS: There were 24 …

Manuscripts, Articles, Book Chapters and Other Papers

Hypophosphatasia (HPP) is a rare metabolic disease resulting from variants in ALPL, inherited in an either autosomal recessive or autosomal dominant manner. Sponsored clinical ALPL testing was offered in the US for individuals with a clinical suspicion of HPP. Gene variants were assessed to determine the likelihood of identifying disease-causing variants, uncover genotype-phenotype relationships, and for further understanding of ALPL variants in the US HPP population. Variants were detected by Sanger sequencing and classified as pathogenic or likely pathogenic (P/LP; positive test result), variant(s) of uncertain significance (indeterminate test result), benign or likely benign (negative test result), or no variants …

Introduction: Physical exercise is a primary defense against age-related cognitive decline and Alzheimer's disease (AD).

Methods: We conducted single-nucleus transcriptomic and chromatin accessibility analyses (snRNA-seq and snATAC-seq) on the hippocampus of mice carrying mutations in the amyloid precursor protein gene (APPNL-G-F) following prolonged voluntary wheel-running exercise.

Results: Exercise mitigates amyloid-induced changes in transcriptome and chromatin accessibility through cell type-specific regulatory networks converging on growth factor signaling, particularly the epidermal growth factor receptor (EGFR) signaling. The beneficial effects of exercise on neurocognition can be blocked by pharmacological inhibition of EGFR and its downstream PI3K signaling. Exercise leads to elevated levels of …
