Flexible Coordinator And Switcher Hubs For Adaptive Task Control, Carrisa V. Cocuzza, Takuya Ito, Douglas H. Schultz, Dabielle D. Bassett, Michael W. Cole

Center for Brain, Biology, and Behavior: Faculty Publications

Functional connectivity (FC) studies have identified at least two large-scale neural systems that constitute cognitive control networks, the frontoparietal network (FPN) and cingulo-opercular network (CON). Control networks are thought to support goal-directed cognition and behavior. It was previously shown that the FPN flexibly shifts its global connectivity pattern according to task goal, consistent with a “flexible hub” mechanism for cognitive control. Our aim was to build on this finding to develop a functional cartography (a multimetric profile) of control networks in terms of dynamic network properties. We quantified network properties in (male and female) humans using a high-control-demand cognitive paradigm …

Validating Tackle Mechanics In American Football: Improving Safety And Performance, Arthur C. Maerlender, Caitlin J. Masterson, Rex Norris, Adam Hinthorne

Center for Brain, Biology, and Behavior: Faculty Publications

Research has helped to understand the risks of injuries of tackling in American football and rugby; however, approaches to teaching and analysis are not well-documented. Shoulder-led tackling has been proposed as a safer approach to tackling even though data on the effectiveness for safety and defensive performance is limited. Additionally, some have argued that safety and effectiveness are incompatible. The purpose of the study was to validate a specific sequence of tackling actions as a tool for teaching safer and more effective tackling skills. Results suggested tackle scores help predict presence of head contact, and that higher tackle scores were …

Cyclic Peptide [R4w4] In Improving The Ability Of First-Line Antibiotics To Inhibit Mycobacterium Tuberculosis Inside In Vitro Human Granulomas, Joshua Hernandez, David Ashley, Ruoqiong Cao, Rachel Abrahem, Timothy Nguyen, Kimberly To, Aram Yegiazaryan, Ajayi Akinwale David, Rakesh Kumar Tiwari, Vishwanath Venketaraman

Pharmacy Faculty Articles and Research

Tuberculosis (TB) is currently one of the leading causes of global mortality. Medical non-compliance due to the length of the treatment and antibiotic side effects has led to the emergence of multidrug-resistant (MDR) strains of Mycobacterium tuberculosis (M. tb) that are difficult to treat. A current therapeutic strategy attempting to circumvent this issue aims to enhance drug delivery to reduce the duration of the antibiotic regimen or dosage of first-line antibiotics. One such agent that may help is cyclic peptide [R₄W₄], as it has been shown to have antibacterial properties (in combination with tetracycline) …

Development Of A Ct Metal Artifact Management Algorithm For Proton Therapy Planning (Ampp) For Head And Neck Cancer Patients, Daniela Branco

Dissertations and Theses (Open Access)

Purpose: Dental amalgams (high Z materials) are common sources of artifacts in Head and Neck (HN) images. Commercial artifact reduction techniques have been offered, but many are impractical, produce inaccurate CT images or are not clinically available, thus not widely implemented. The goal of this work is to use CT gantry tilts to develop and evaluate a stereoscopic HN metal artifact management algorithm and investigate its improvement in proton treatment planning.

Methods: The in-house CT metal artifact management method for proton planning (AMPP) uses two angled CT scans to generate a single image set with no metal artifacts posterior …

Data Augmentation For Deep-Learning-Based Electroencephalography, Elnaz Lashgari, Dehua Liang, Uri Maoz

Psychology Faculty Articles and Research

Background

Data augmentation (DA) has recently been demonstrated to achieve considerable performance gains for deep learning (DL)—increased accuracy and stability and reduced overfitting. Some electroencephalography (EEG) tasks suffer from low samples-to-features ratio, severely reducing DL effectiveness. DA with DL thus holds transformative promise for EEG processing, possibly like DL revolutionized computer vision, etc.

New method

We review trends and approaches to DA for DL in EEG to address: Which DA approaches exist and are common for which EEG tasks? What input features are used? And, what kind of accuracy gain can be expected?

Results

DA for DL on EEG begun …

Another goal of this work was to perturb the usual and the unusual photosynthesis systems that pineapple has maintained for millions of years during the evolution of circadian genes for efficient water conservation by dark photosynthesis. To detect such photosynthesis …

Pre-Stretching Of The Hamstrings Before Squatting Acutely Increases Biceps Femoris Thickness Without Impairing Exercise Performance, Thiago Barbosa Trindade, Leônidas Oliveira Neto, José Claudino Neto Pita, Vagner Deuel De Oliveira Tavares, Paulo Moreira Silva Dantas, Brad J. Schoenfeld, Jonato Prestes

Publications and Research

Background: Bilateral squat exercise is widely used in resistance training (RT) programs to increase lower limb strength and muscle mass, but this exercise does not result in significant hypertrophy of the hamstrings. It has been speculated that stretching between sets with a certain degree of tension results in muscle hypertrophy, while acute stretching could decrease performance during maximal contractions.

Objective: This study investigated the acute effects of hamstring stretching before bilateral squatting on muscle thickness (MT), electromyography (EMG), and total training volume (TTV) on exercise performance.

Methods: Fourteen resistance-trained young men, with ∼7.5 years of RT experience, performed the 10 …

Recombinant Human Proteoglycan-4 Mediates Interleukin-6 Response In Both Human And Mouse Endothelial Cells Induced Into A Sepsis Phenotype, Holly A. Richendrfer, Mitchell M. Levy, Khaled A. Elsaid, Tannin A. Schmidt, Ling Zhang, Ralph Cabezas, Gregory D. Jay

Pharmacy Faculty Articles and Research

Objectives:

Sepsis is a leading cause of death in the United States. Putative targets to prevent systemic inflammatory response syndrome include antagonism of toll-like receptors 2 and 4 and CD44 receptors in vascular endothelial cells. Proteoglycan-4 is a mucinous glycoprotein that interacts with CD44 and toll-like receptor 4 resulting in a blockade of the NOD-like receptor pyrin domain-containing-3 pathway. We hypothesized that endothelial cells induced into a sepsis phenotype would have less interleukin-6 expression after recombinant human proteoglycan 4 treatment in vitro.

Design:

Enzyme-linked immunosorbent assay and reverse transcriptase-quantitative polymerase chain reaction to measure interleukin-6 protein and gene expression.

Setting: …

Sensors And Wearables In Oncology: A Study Of The Barriers And Facilitators To Adoption, Sam Hanna

Doctor of Philosophy in Translational Health Sciences Dissertations

Innovation, although a subject of considerable debate (e.g., Baregheh et al., 2009; Christensen, 1997), can be defined as the introduction and dissemination of a new or a different idea into use or practice that drives impact (Solis and Sinfield, 2014). Many studies and editorials have highlighted the complexity of the United States health system and detailed the slow speed by which innovative ideas materialize into impactful innovations (Continuing America’s leadership (2017); England & Stewart (2007); Kannampallil, Schauer, Cohen & Patel (2011)). While there are many advances in sensor and wearable technologies in this instance, the adoption rate by oncologists has …

Mechanical Thrombectomy For Acute Ischemic Stroke In The Cardiac Catheterization Laboratory., Steven A Guidera, Sudhir Aggarwal, J Doyle Walton, David Boland, Roy Jackel, Jeffrey D Gould, Brooke Kearins, Joseph Mcgarvey, Yan Qi, Brian Furlong

Department of Radiology & Diagnostic Medical Imaging

OBJECTIVES: The aim of this study was to determine the feasibility of establishing a mechanical thrombectomy (MT) program for acute ischemic stroke in a community hospital using interventional cardiologists working closely with neurologists.

BACKGROUND: American Heart Association/American Stroke Association 2018 guidelines give a Class I (Level of Evidence: A) recommendation for MT in eligible patients with large vessel occlusion stroke. Improvement in neurological outcomes with MT is highly time sensitive. Most hospitals do not have trained neurointerventionalists to perform MT, leading to treatment delays that reduce the benefit of reperfusion therapy.

METHODS: An MT program based in the cardiac catheterization …
