Towards A Study Protocol: A Data-Driven Workflow To Identify Error Sources In Direct Ink Write Mechatronics, Hein Htet Aung, Quynh D. Tran, Pawan Tripathi, Roger H. French, Laura S. Bruckman

Faculty Scholarship

Using Direct Ink Write (DIW) technology in a rapid and large-scale production requires reliable quality control for printed parts. Data streams generated during printing, such as print mechatronics, are massive and diverse which impedes extracting insights. In our study protocol approach, we developed a data-driven workflow to understand the behavior of sensor-measured X- and Y-axes positional errors with process parameters, such as print velocity and velocity control. We uncovered patterns showing that instantaneous changes in the velocity, when the build platform accelerates and decelerates, largely influence the positional errors, especially in the X-axis due to the hardware architecture. Since DIW …

Faculty, Staff and Students Publications

Human noroviruses, globally the main cause of viral gastroenteritis, show strain specific affinity for histo-blood group antigens (HBGA) and can successfully be propagated ex vivo in human intestinal enteroids (HIEs). HIEs established from jejunal stem cells of individuals with different ABO, Lewis and secretor geno- and phenotypes, show varying susceptibility to such infections. Using bottom-up glycoproteomic approaches we have defined and compared the N-linked glycans of glycoproteins of seven jejunal HIEs. Membrane proteins were extracted, trypsin digested, and glycopeptides enriched by hydrophilic interaction liquid chromatography and analyzed by nanoLC-MS/MS. The Byonic software was used for glycopeptide identification followed by hands-on …

Pharmacy Faculty Articles and Research

The emergence of multidrug-resistant (MDR) strains causes severe problems in the treatment of microbial infections owing to limited treatment options. Antimicrobial peptides (AMPs) are drawing considerable attention as promising antibiotic alternative candidates to combat MDR bacterial and fungal infections. Herein, we present a series of small amphiphilic membrane-active cyclic peptides composed, in part, of various nongenetically encoded hydrophilic and hydrophobic amino acids. Notably, lead cyclic peptides 3b and 4b showed broad-spectrum activity against drug-resistant Gram-positive (MIC = 1.5–6.2 µg/mL) and Gram-negative (MIC = 12.5–25 µg/mL) bacteria, and fungi (MIC = 3.1–12.5 µg/mL). Furthermore, lead peptides displayed substantial antibiofilm action comparable …

The Plague Of Athens, Cameron Drylie

Student Academic Conference

The purpose of this study is to use historical analysis, biology, and linguistics to evaluate the reason one of early humanity's greatest civilizations fell. 449 BC marked the end of the Greco-Persian War and the crowning of two new dominate city-states in the Mediterranean, Athens and Sparta. The tensions of these two ideologically different civilizations rose for eighteen years before the two clashed in the bloodiest conflict the world had ever seen at the time. Led by the great Pericles, Athens struggled to resist the most powerful land force of the time, causing him to retreat into the city walls. …

Pediatric hematopoietic cell transplant (HCT) recipients exhibit poor serologic responses to influenza vaccination early after transplant. To facilitate the optimization of influenza vaccination timing, we sought to identify B- and T-cell subpopulations associated with influenza vaccine immunogenicity in this population. We used mass cytometry to phenotype peripheral blood mononuclear cells collected from pediatric HCT recipients enrolled in a multicenter influenza vaccine trial comparing high- and standard-dose formulations over 3 influenza seasons (2016-2019). We fit linear regression models to estimate relationships between immune cell subpopulation numbers before vaccination and prevaccination to postvaccination geometric mean fold rises in antigen-specific (A/H3N2, A/H1N1, and …

Best Practice: Implementation Of A Central Line Bundle To Reduce Central Line-Associated Bloodstream Infections, Alexis N. Montero

MSN Capstone Projects

Central line-associated bloodstream infections (CLABSIs) are among the most frequent health care-associated infections and are reported to be correlated with an increased number of inpatient days, higher cost, and attributable mortality rates (Devrim et al., 2016). For this reason, central line bundles (CLB) have been widely used in hospitals to aid in the decrease of CLABSIs. Through implementation of the prevention strategies included in CLBs, CLABSIs can be reduced by greater than fifty percent (Devrim et al., 2016). A decrease in CLABSIs is clinically significant with the avoidance of negative patient outcomes and a decrease in healthcare costs (Rinke et …

Mathematical Modeling For Dental Decay Prevention In Children And Adolescents, Mahdiyeh Soltaninejad

Dissertations

The high prevalence of dental caries among children and adolescents, especially those from lower socio-economic backgrounds, is a significant nationwide health concern. Early prevention, such as dental sealants and fluoride varnish (FV), is essential, but access to this care remains limited and disparate. In this research, a national dataset is utilized to assess sealants' reach and effectiveness in preventing tooth decay, particularly focusing on 2nd molars that emerge during early adolescence, a current gap in the knowledge base. FV is recommended to be delivered during medical well-child visits to children who are not seeing a dentist. Challenges and facilitators in …

Covid-19 And Church Attendance Behavior Trends: Evidence From Ghanaian Pentecostal-Charismatic Churches, Justice A. Arthur, Lydia Andoh-Quainoo

Spiritus: ORU Journal of Theology

The concept of religious economy views churches as corporate entities, pastors as marketers offering a range of products, and church members as consumers whose preferences shape the goods and services provided by ministers. Within this framework, church members react quickly to changing economic, social, and cultural conditions. The COVID-19 pandemic has not only had an economic impact, with job losses and financial struggles, but has also brought about social and cultural changes that have affected consumer behavior in many areas of life worldwide. For instance, during the pandemic, church gatherings were restricted or prohibited, socializing was replaced with social distancing, …

Modern Approaches To Treating Hospital Acquired Infections: An Overview Of Current Treatments Using Antibiotics And New Therapies Centered Around Photo-Activated Porphyrins, Meghan Johns

Senior Honors Theses

Annually, hospital-acquired infections (HAIs) affect hundreds of thousands of people in the U.S. and impose a great economic burden. The current problem is further exacerbated due to the failure of traditional treatment strategies considering the rise in antimicrobial resistance rates. Besides the fact that antimicrobial resistances complicates clinical treatment strategies, patients are also more vulnerable to secondary infections and complications from prolonged antibiotic use. As a result, research investigating novel treatment strategies for bacterial infections has recently increased. A strategy using porphyrin-based compounds is showing promise. Porphyrins and their derivatives have exhibited bactericidal effects against Gram-positive bacteria by the destruction …

School of Medicine Faculty Publications

Objectives: Sepsis is one of the most common, costly, and misdiagnosed conditions in U.S. emergency departments (EDs). ED providers often treat on nonspecific signs, subjective suspicion, or presumption of infection, resulting in over- and undertreatment. An increased understanding of host response has opened a new direction for sepsis diagnostics. The IntelliSep test is a U.S. Food and Drug Administration–cleared cellular host response diagnostic that could help distinguish sepsis in ED settings. Our objective was to evaluate the potential of the cellular host response test to expedite appropriate care for patients who present with signs of infection. Methods: We performed a …

Reducing Central Line-Associated Bloodstream Infections (Clabsi) With Chlorhexidine-Impregnated Dressings, Sara Garcia

MSN Capstone Projects

Mitigating and eradicating central line-associated bloodstream infections (CLABSI) is a vital patient safety priority. These healthcare-associated infections lead to patient fatalities and incur costly, preventable expenses. Therefore, it is imperative to assess central venous catheter (CVC) maintenance protocols to mitigate the likelihood of infection. Federal guidelines advocate using chlorhexidine (CHG) dressings to lower this risk (Centers for Disease Control and Prevention, 2017). A comprehensive central line maintenance bundle includes incorporating a CHG dressing as a critical measure in reducing the risk of CLABSI (Buetti et al., 2022). Consequently, the escalating infection rates underscore the necessity for implementing CHG dressings (Buetti …

Regulation And Therapeutic Targeting Of Virus-Specific Resident Memory T Cells, Jordan Fredriksen Isaacs

Dartmouth College Ph.D Dissertations

CD8+ T cells are critical to the immune response to pathogens, as they kill infected cells and generate immunologic memory. Following infection, antigen-specific T cells expand approximately 10,000-fold and migrate to sites of inflammation in order to clear the pathogen. Once infection is resolved, a small pool of memory T cells persist in circulation and within tissues ready to respond rapidly upon re-exposure. Given the importance of CD8+ T cells, significant efforts have been made over the years to better understand how different memory T cell subsets are established, maintained, and regulated. The most recently identified subset, resident memory T …
