Role Of Biomechanical Forces In Hyperfiltration-Mediated Glomerular Injury In Congenital Anomalies Of The Kidney And Urinary Tract., Tarak Srivastava, Ganesh Thiagarajan, Uri S. Alon, Ram Sharma, Ashraf El-Meanawy, Ellen T. Mccarthy, Virginia J. Savin, Mukut Sharma

Manuscripts, Articles, Book Chapters and Other Papers

Congenital anomalies of the kidney and urinary tract (CAKUT) including solitary kidney constitute the main cause of progressive chronic kidney disease (CKD) in children. Children born with CAKUT develop signs of CKD only during adolescence and do not respond to renin-angiotensin-aldosterone system blockers. Early cellular changes underlying CKD progression to end-stage renal disease by early adulthood are not well understood. The mechanism of maladaptive hyperfiltration that occurs from loss of functional nephrons, including solitary kidney, is not clear. We re-examine the phenomenon of hyperfiltration in the context of biomechanical forces with special reference to glomerular podocytes. Capillary stretch exerts tensile …

Chat Expression In Chlamydia Muridarum-Infected Female Murine Genital Tract, Hallie Sartain

Undergraduate Honors Theses

Chlamydia trachomatis is the most prevalent agent of bacterial sexually transmitted infections in the world. However, a profuse number of cases are unreported, as the infection is often asymptomatic. Sequelae such as pelvic inflammatory disease, an increased risk of cervical cancer, premature birth, and perinatal infections in pregnant women can occur. Inflammation occurs in the body in response to infection or injury. Although inflammation can lead to some unwanted secondary effects, such as pain, it serves to return the body to homeostasis by restoring injured tissues and eliminating pathogens. One recently identified connection between the central nervous system and the …

The Effects Of Spondylolisthesis On The Human Body, Kayla L. Govoni

Senior Honors Projects

Spondylolisthesis is a rare and unknown disorder to many. The anatomical perplexity beneath its diagnosis is extensive yet crucial to truly understanding this unique anomaly. As a condition that is too often undistinguished and unexplained to countless, it warrants and demands undisputed attention. Spondylolisthesis is an atypical spinal disorder characterized by one vertebra sliding forward in position over the vertebra below it (Rodts, 2017). The victim of this condition faces excruciating pain radiating throughout one’s lower back and frequently into the lower extremities. In cases of increased severity, individuals pursue a variety of treatment modalities ranging from conservative measures such …

Mallampati Scoring And Its Relation To Obstructive Sleep Apnea, Austin Korczak

Honors Capstones

According to the American Sleep Apnea Association potentially 80% of moderate to severe cases of Obstructive Sleep Apnea (OSA) go undiagnosed with even optimistic estimates stating that at least 22 million Americans are afflicted by the disorder. These numbers are expected to continue to increase due to the rising rates of obesity in America. As a result, reliable criteria that can help physicians accurately predict the presence of an underlying sleep disorder, whose symptoms are masked during the day, is highly sought after. The objective of this research is to begin defining these criteria via a literature review of articles …

Bk Channels Mediate Synaptic Plasticity Underlying Habituation In Rats, Tariq Zaman, Cleusa De Oliveira, Mahabba Smoka, Chakravarthi Narla, Michael O. Poulter, Susanne Schmid

Anatomy and Cell Biology Publications

Habituation is a basic form of implicit learning and represents a sensory filter that is disrupted in autism, schizophrenia, and several other mental disorders. Despite extensive research in the past decades on habituation of startle and other escape responses, the underlying neural mechanisms are still not fully understood. There is evidence from previous studies indicating that BK channels might play a critical role in habituation. We here used a wide array of approaches to test this hypothesis. We show that BK channel activation and subsequent phosphorylation of these channels are essential for synaptic depression presumably underlying startle habituation in rats, …

Metformin To Augment Strength Training Effective Response In Seniors (Masters): Study Protocol For A Randomized Controlled Trial, Douglas E. Long, Bailey D. Peck, Jenny L. Martz, S. Craig Tuggle, Heather M. Bush, Gerald Mcgwin, Philip A. Kern, Marcas M. Bamman, Charlotte A. Peterson

Physical Therapy Faculty Publications

Background: Muscle mass and strength are strong determinants of a person’s quality of life and functional independence with advancing age. While resistance training is the most effective intervention to combat age-associated muscle atrophy (sarcopenia), the ability of older adults to increase muscle mass and strength in response to training is blunted and highly variable. Thus, finding novel ways to complement resistance training to improve muscle response and ultimately quality of life among older individuals is critical. The purpose of this study is to determine whether a commonly prescribed medication called metformin can be repurposed to improve the response to resistance …

High School Student Concussion Recovery Program: Teacher Involvement In Student Academic Transitions To Classroom And To Sports, Brittany Diego

Scholarly and Creative Works Conference (2015 - 2021)

Many symptoms of concussions can greatly interfere with the cognitive abilities and skills students use in school. Although students may have similar symptoms, they experience concussions differently. Students returning to the classroom from a concussion often have different needs and abilities.

Research shows that a formal, individualized protocol to treat suspected concussions, both academically and physically, is vital to the successful recovery of each student. Much research is available on concussions for professional athletes, specifically related to recovery and returning to their sport. However, there is little research about high school students regarding concussions. Concussion recovery programs for high school …

Novel Genetic Variants Associated With Child Refractory Esophageal Stricture With Food Allergy By Exome Sequencing., Min Yang, Min Xiong, Huan Chen, Lanlan Geng, Peiyu Chen, Jing Xie, Shui Qing Ye, Ding-You Li, Sitang Gong

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Refractory esophageal stricture (RES) may be attributed to food allergy. Its etiology and pathogenesis are not fully understood. Identification of novel genetic variants associated with this disease by exome sequencing (exome-seq) may provide new mechanistic insights and new therapeutic targets.

METHODS: To identify new and novel disease-associating variants, whole-exome sequencing was performed on an Illumina NGS platform in three children with RES as well as food allergy.

RESULTS: A total of 91,024 variants were identified. By filtering out 'normal variants' against those of the 1000 Genomes Project, we identified 12,741 remaining variants which are potentially associated with RES plus …

Shear Driven Micro-Fluidic Pump For Cardiovascular Applications, Nihad E. Daidzic

Aviation Department Publications

A valveless shear-driven micro-fluidic pump design (SDMFP) for hemodynamic applications is presented in this work. One of the possible medical and biomedical applications is in-vivo hemodynamic (human blood circulation) support/assist. One or more SDMFPs can be inserted/implanted into vascular lumens in a form of a stent/duct in series and/or in parallel (bypass duct) to support blood circulation in-vivo. A comprehensive review of various micro-pump designs up to about mid 2000’s is given in [1,2]. Many of micropump designs considered are not suitable for in-vivo or even in-vitro medical/biomedical applications.

Operating principles, design, and SDMFP features are given in [3]. A …

Mll3/Mll4 Are Required For Cbp/P300 Binding On Enhancers And Super-Enhancer Formation In Brown Adipogenesis., Binbin Lai, Ji-Eun Lee, Younghoon Jang, Lifeng Wang, Weiqun Peng, Kai Ge

Anatomy and Regenerative Biology Faculty Publications

Histone H3K4me1/2 methyltransferases MLL3/MLL4 and H3K27 acetyltransferases CBP/p300 are major enhancer epigenomic writers. To understand how these epigenomic writers orchestrate enhancer landscapes in cell differentiation, we have profiled genomic binding of MLL4, CBP, lineage-determining transcription factors (EBF2, C/EBPβ, C/EBPα, PPARγ), coactivator MED1, RNA polymerase II, as well as epigenome (H3K4me1/2/3, H3K9me2, H3K27me3, H3K36me3, H3K27ac), transcriptome and chromatin opening during adipogenesis of immortalized preadipocytes derived from mouse brown adipose tissue (BAT). We show that MLL4 and CBP drive the dynamic enhancer epigenome, which correlates with the dynamic transcriptome. MLL3/MLL4 are required for CBP/p300 binding on enhancers activated during adipogenesis. Further, MLL4 …

Toward A Research Agenda For Oncology Physical Therapy, Lucinda Pfalzer, Nicole L. Stout, Shana Harrington, Mary Insana Fisher

Physical Therapy Faculty Publications

Research Round-up: Cancer survivors frequently experience cancer treatment–related functional impairments and disability. While a growing body of evidence supports the effectiveness of rehabilitation interventions for these individuals, there are significant gaps in the existing literature and no interdisciplinary agreement on the priorities for cancer rehabilitation research. In 2016, the Oncology Section revised its strategic plan and set an objective to create an oncology rehabilitation research agenda for the physical therapy (PT) profession. To achieve this goal, the scope of the agenda, a development and review process, and dissemination plan need to be developed.

Cancer As A Metabolic Disease, Javaria Haseeb

Honors Senior Capstone Projects

Despite decades of intensive scientific and medical efforts to develop efficient and effective treatments for cancer, it remains one of the prime causes of death today. For example, in 2016, there will be an estimated 1,685,210 new cases of cancer and 595,690 deaths due to cancer in the United States alone (National Cancer Institute). Worldwide in 2012, there were an estimated 14 million new cases of cancer and 8.2 million deaths due to cancer. In order to come up with better methods of detection and more successful modes of treatment, it is crucial that scientists understand the depth of not …

Can Time-Resolved Nirs Provide The Sensitivity To Detect Brain Activity During Motor Imagery Consistently?, Androu Abdalmalak, Daniel Milej, Mamadou Diop, Mahsa Shokouhi, Lorina Naci, Adrian M. Owen, Keith St. Lawrence

Anatomy and Cell Biology Publications

Previous functional magnetic resonance imaging (fMRI) studies have shown that a subgroup of patients diagnosed as being in a vegetative state are aware and able to communicate by performing a motor imagery task in response to commands. Due to the fMRI's cost and accessibility, there is a need for exploring different imaging modalities that can be used at the bedside. A promising technique is functional near infrared spectroscopy (fNIRS) that has been successfully applied to measure brain oxygenation in humans. Due to the limited depth sensitivity of continuous-wave NIRS, time-resolved (TR) detection has been proposed as a way of enhancing …

Anatomical Knowledge Retention In Changing Curricula, Alexa Lean, Juliet Lee, Ellen Goldman, Gisela Butera, Kirsten Brown, Rosalyn Jurjus

GW Research Days 2016 - 2020

Traditionally anatomy is one of the first subjects taught in medical school. Practicing physicians have commented on medical students’ poor anatomical knowledge in surgically oriented clerkships. Literature also shows that correlating clinical and anatomical sciences throughout early medical education may improve anatomical knowledge retention. With major medical school curricular changes happening across the nation, more quantitative data confirming this correlation is needed.

The medical curriculum at the George Washington University School of Medicine recently underwent reorganization, transforming an earlier discipline-based curriculum to that of an integrated system-based one. In order to determine whether reorganization has an effect on anatomical knowledge …

The Effect Of Barefoot Running Using Two Running Styles On Lower Extremity Joint Reaction Forces, Jamie M. Rogers

Senior Honors Theses

Running is a popular worldwide activity with many varying biomechanical techniques. Investigating potential differences in joint forces can be beneficial in determining if there is a superior biomechanical running pattern. Previous research compared barefoot and shod running, as well as the kinetic effects of varied running styles. The current study investigated the differences in internal joint reaction forces (JRF) at the hip, knee, and ankle joints during running with two different styles. Ten male and ten female participants who naturally run with a rearfoot strike pattern were included in this study. Each subject ran barefoot on an instrumented treadmill for …

Aging And Muscle Fatigability In The Upper Extremity, Andrew Kuplic

Master's Theses (2009 -)

Aging is accompanied by reductions in strength and contraction velocity, and increased fatigability of limb muscles during high-velocity dynamic contractions. These age-related changes affect functional tasks and are well described for the lower limb, with less known about the upper limb muscles. The aims of the thesis were to compare in young and old men and women: (1) maximal torque and power of the elbow flexor muscles across a range of isokinetic velocities, and (2) the neural (supraspinal) and muscular mechanisms of fatigue induced by high-velocity dynamic contractions of the elbow flexor muscles. 28 young (23.2 ± 2.6 years) men …

Genomic Contraindications For Heart Transplantation., Danton S. Char, Gabriel Lázaro-Muñoz, Aliessa Barnes, David Magnus, Michael J. Deem, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Genome sequencing raises new ethical challenges. Decoding the genome produces new forms of diagnostic and prognostic information; however, the information is often difficult to interpret. The connection between most genetic variants and their phenotypic manifestations is not understood. This scenario is particularly true for disorders that are not associated with an autosomal genetic variant. The analytic uncertainty is compounded by moral uncertainty about how, exactly, the results of genomic testing should influence clinical decisions. In this Ethics Rounds, we present a case in which genomic findings seemed to play a role in deciding whether a patient was to be listed …
