Automatic Generation And Novel Validation Of Patient-Specific, Anatomically Inclusive Scoliosis Models For Biomechanics-Informed Surgical Planning, Austin Tapp, Michel Audette, James Bennett 2021 Old Dominion University

Automatic Generation And Novel Validation Of Patient-Specific, Anatomically Inclusive Scoliosis Models For Biomechanics-Informed Surgical Planning, Austin Tapp, Michel Audette, James Bennett

College of Engineering & Technology (Batten) Posters

Scoliosis is an abnormal spinal curvature of greater than 10 degrees. Severe scoliotic deformities are addressed with highly invasive procedures: anterior or posterior spinal fusion approaches. This invasiveness is due, in part, to the constraints of current surgical planning, which utilizes computed tomography (CT) scans unable to discern spinal ligaments that are dissected to make the spine sufficiently compliant for correction. If localization of ligaments and soft tissues were achieved pre-operatively, corrective procedures could become safer and more efficient by using finite element (FE) biomechanical simulations to determine decreased incidences of ligament releases. This research aims to achieve ligament localization ...

Neurophysiology Of Space Medicine: A Literature Review, Jose R. Velasquez

MEDI 9331 Scholarly Activities Clinical Years

Space medicine is becoming an essential and expanding clinical discipline. Acquiring a deeper and complete picture understanding of the multi-systemic response due to space on human health and function is essential to ensure the success of future space exploration. A comprehensive review of the literature was performed using PubMed and focused on the current neurophysiologic findings of the central nervous system’s response to space. Ground-based analogues, which mimic the effects of microgravity, and actual spaceflight studies have been used to analyze these physiologic adaptations to space. Overall, cerebellar, sensorimotor and vestibular brain regions seem to be affected the most ...


Evidence-Based Practice: Delaying Infant Bathing, Gabrielle Wadle, Grace Frankland 2021 Murray State University

Evidence-Based Practice: Delaying Infant Bathing, Gabrielle Wadle, Grace Frankland

Scholars Week

A hospital's policy regarding infant bathing is currently not congruent with best nursing practice. The hospital’s current policy is to bathe an infant once they are stable and their rectal temperature is at or above 98.6 °F. Although the infant may become stable within the first 24-hours of birth, the World Health Organization recommends that, “Bathing should be delayed until 24 hours after birth.” (2013, p. 4). Research has been completed to support delaying infant bathing until 24 hours post-delivery, suggesting potential modifications to current policy.

Open Access Publications by UMMS Authors

OBJECTIVE: The immediate signals that couple exercise to metabolic adaptations are incompletely understood. Nicotinamide adenine dinucleotide phosphate oxidase 4 (Nox4) produces reactive oxygen species (ROS) and plays a significant role in metabolic and vascular adaptation during stress conditions. Our objective was to determine the role of Nox4 in exercise-induced skeletal muscle metabolism.

METHODS: Mice were subjected to acute exercise to assess their immediate responses. mRNA and protein expression responses to Nox4 and hydrogen peroxide (H2O2) were measured by qPCR and immunoblotting. Functional metabolic flux was measured via ex vivo fatty acid and glucose oxidation assays using (14)C-labeled palmitate and ...


Hands, Marc Perlman 2021 Albany Medical College

Hands, Marc Perlman

HCA Healthcare Journal of Medicine

“Hands” is inspired by my first encounter with a donor in the cadaver lab during my first year of medical school. This poem highlights the intimate relationship between the medical student and their “first patient” and captures the factors that helped me realize the grandeur of the dissecting experience. Through an awareness of the donor’s hands, I became viscerally aware that the cadaver is a real human being who donated their corporeality to help students learn. The bilateral vulnerability of this experience is a critical milestone in the development of health care providers. Given the recent transition from in-person ...

Antisense oligonucleotides (ASOs) are emerging as a promising class of therapeutics for neurological diseases. When injected directly into the cerebrospinal fluid, ASOs distribute broadly across brain regions and exert long-lasting therapeutic effects. However, many phosphorothioate (PS)-modified gapmer ASOs show transient motor phenotypes when injected into the cerebrospinal fluid, ranging from reduced motor activity to ataxia or acute seizure-like phenotypes. The effect of sugar and phosphate modifications on these phenotypes has not previously been systematically studied. Using a behavioral scoring assay customized to reflect the timing and nature of these effects, we show that both sugar and phosphate modifications influence ...

COVID-19 Publications by UMMS Authors

The current study aims to develop a safe and highly immunogenic COVID-19 vaccine. The novel combination of a DNA vaccine encoding the full-length Spike (S) protein of SARS-CoV-2 and a recombinant S1 protein vaccine induced high level neutralizing antibody and T cell immune responses in both small and large animal models. More significantly, the co-delivery of DNA and protein components at the same time elicited full protection against intratracheal challenge of SARS-CoV-2 viruses in immunized rhesus macaques. As both DNA and protein vaccines have been proven safe in previous human studies, and DNA vaccines are capable of eliciting germinal center ...

Glial Cell Dysfunction In C9orf72-Related Amyotrophic Lateral Sclerosis And Frontotemporal Dementia, Mehdi Ghasemi, Kiandokht Keyhanian, Catherine Douthwright 2021 University of Massachusetts Medical School

Glial Cell Dysfunction In C9orf72-Related Amyotrophic Lateral Sclerosis And Frontotemporal Dementia, Mehdi Ghasemi, Kiandokht Keyhanian, Catherine Douthwright

Open Access Publications by UMMS Authors

Since the discovery of the chromosome 9 open reading frame 72 (C9orf72) repeat expansion mutation in 2011 as the most common genetic abnormality in amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease) and frontotemporal dementia (FTD), progress in understanding the signaling pathways related to this mutation can only be described as intriguing. Two major theories have been suggested-(i) loss of function or haploinsufficiency and (ii) toxic gain of function from either C9orf72 repeat RNA or dipeptide repeat proteins (DPRs) generated from repeat-associated non-ATG (RAN) translation. Each theory has provided various signaling pathways that potentially participate in ...

Neuronal Post-Developmentally Acting Sax-7s/L1cam Can Function As Cleaved Fragments To Maintain Neuronal Architecture In C. Elegans [Preprint], Virginie E. Desse, Cassandra R. Blanchette, Paola N. Perrat, Claire Y. Benard

University of Massachusetts Medical School Faculty Publications

Whereas remarkable advances have uncovered mechanisms that drive nervous system assembly, the processes responsible for the lifelong maintenance of nervous system architecture remain poorly understood. Subsequent to its establishment during embryogenesis, neuronal architecture is maintained throughout life in the face of the animal’s growth, maturation processes, the addition of new neurons, body movements, and aging. The C. elegans protein SAX-7, homologous to the vertebrate L1 protein family, is required for maintaining the organization of neuronal ganglia and fascicles after their successful initial embryonic development. To dissect the function of sax-7 in neuronal maintenance, we generated a null allele and ...
