Abnormal Response Of Costal Chondrocytes To Acidosis In Patients With Chest Wall Deformity, A. Asmar, Iurii Semenov, R. Kelly Jr., Michael Stacey

Bioelectrics Publications

Costal cartilage is much understudied compared to the load bearing cartilages. Abnormally grown costal cartilages are associated with the inherited chest wall deformities pectus excavatum and pectus carinatum resulting in sunken or pigeon chest respectively. A lack of understanding of the ultrastructural and molecular biology properties of costal cartilage is a major confounder in predicting causes and outcomes of these disorders. Due to the avascular nature of cartilage, chondrocytes metabolize glycolytically, producing an acidic environment. During physical activity hydrogen ions move within cartilage driven by compressive forces, thus at any one time, chondrocytes experience transient changes in pH. A variety …

Can Nanotechnology Be The Leading Method In Detecting And Treating Cerebral Tumors?, Daniel D. Singh, Zuri Jules-Culver

OUR Journal: ODU Undergraduate Research Journal

Nanotechnology refers to the manipulation or design of materials and structures with desired features in the 1nm–1000 nm size range. The blood brain barrier (BBB) is a major obstacle that drugs must overcome in order to reach tumor cells. The role of this barrier is to transport essential nutrients while protecting and regulating the internal environment. Nanoparticles have been shown to transport drugs through this barrier and accumulate in tumor cells. This is significant since nanoparticles are drug carriers allowing chemotherapeutic drugs to accumulate in target areas (Sun et al., 2017). This is possible because they are able to be …

The Revolution Will Be Open-Source: How 3d Bioprinting Can Change 3d Cell Culture, Robert D. Bruno, John Reid, Patrick C. Sachs

Medical Diagnostics & Translational Sciences Faculty Publications

(First paragraph) The development of three-dimensional culture scaffolds represents a revolutionary step forward for in vitro culture systems. Various synthetic and naturally occurring substrates have been developed that support 3D growth of cells. In most fields, including mammary gland biology and tumorigenesis, the two most common substrates used are the basement membrane rich extracellur matrix (ECM) isolated from EngelbrethHolm-Swarm (EHS) mouse sarcomas (e.g. Matrigel) and collagen extracted from rat-tails. The processes of 3D culture in these two substrates has remained unchanged for nearly half a century: cells are either mixed with unpolymerized matrix to disperse them randomly throughout the substrate …

Treatment Of Auditory Processing In Noise In Individuals With Mild Aphasia: Pilot Study, Anastasia M. Raymer, Hilary M. Sandberg, Kathryn S. Schwartz, Ginger S. Watson, Stacie I. Ringleb

Communication Disorders & Special Education Faculty Publications

Purpose: Listening in noise challenges listeners with auditory comprehension impairments in aphasia. We examined the effects of Trivia Game, a computerized program with questions spoken in increasing levels of background noise with success in the game.

Methods: We piloted Trivia Game in four individuals with chronic aphasia and mild auditory comprehension impairments. Participants played Trivia Game for 12 twenty-minute sessions. In addition to the Western Aphasia Battery (WAB), we measured outcomes on Quick Speech in Noise (QSIN), a sentence repetition test, administered in auditory (AUD) and auditory+visual (AV) conditions as signal-to-noise ratio varied from 25 to 0 dB.

Results: All …

Walking Biomechanics And Energetics Of Individuals With A Visual Impairment: A Preliminary Report, Hunter J. Bennett, Kevin A. Valenzuela, Kristina Fleenor, Steven Morrison, Justin A. Haegele

Human Movement Sciences & Special Education Faculty Publications

Purpose.

Although walking gait in sighted populations is well researched, few studies have investigated persons with visual impairments (VIs). Given the lack of physical activity in people with VIs, it is possible that reduced efficiency in walking could adversely affect activity. The purposes of this preliminary study were to (1) examine the biomechanics and energetics utilized during independent and guided walking in subjects with VIs, and (2) compare gait biomechanics between people with VIs and sighted controls.

Methods.

Three-dimensional motion capture and force platforms were used during independent and guided walking at self-selected speeds. Joint angles, moments, external work, and …

Toxic Environmental Risk Factors For Alzheimer's Disease: A Systematic Review, Oluwaseyi Olayinka, Olaniyi O. Olayinka, Brook T. Alemu, Muge Akpinar-Elci, George T. Grossberg

Community & Environmental Health Faculty Publications

There is growing evidence of a possible association between toxic environmental factors and Alzheimer’s disease (AD), a disabling neurodegenerative condition with no known cause. Previous reviews of toxic environmental factors for AD either focused on occupational exposures or used a non-systematic methodology. The objective of this systematic review is to assess the evidence on the link between AD and exposure to a variety of toxic environmental risk factors beyond the work environment. Structured database search was used to identify relevant studies. Twenty-nine eligible studies examining the effect of various toxic environmental agents including electromagnetic fields, solvents, pesticides, toxic metals, and …

Dysmenorrhea Among High-School Students And It's Associated Factors In Kuwait, Sharefah Al-Matouq, Hessah Al-Mutairi, Ohood Al-Mutairi, Fatima Abdulaziz, Dana Al-Basri, Mona Al-Enzi, Abdullah Al-Taiar

Community & Environmental Health Faculty Publications

Background

Although dysmenorrhea is not a life-threatening condition, it can cause a substantial burden on individuals and communities. There is no data on the prevalence of dysmenorrhea in Kuwait. This study aimed to estimate the prevalence of dysmenorrhea among female public high-school students in Kuwait and investigate factors associated with dysmenorrhea.

Methods

A cross-sectional study using multistage cluster sampling with probability proportional to size method was conducted on 763 twelfth grade female public high-school students (aged 16–21 years). We used face-to-face interview with a structured questionnaire to collect data on dysmenorrhea and presumed risk factors. Weight and height of the …

Prevalence Of Low Back Pain Among Adolescents In Relation To The Weight Of School Bags, Fatemah Akbar, Muneera Albesharah, Jumana Al-Baghli, Farah Bulbul, Dana Mohammad, Bann Qadoura, Abdullah Al-Taiar

Community & Environmental Health Faculty Publications

Background

The association between the weight of school bag and Low Back Pain (LBP) amongst students remains under intense debate worldwide. This study aimed to estimate the prevalence of LBP amongst public high school students (14 to 19 years) in Kuwait and to investigate the association between LBP and the weight of school bags.

Methods

An analytical cross-sectional study using multistage cluster random sampling with probability proportional to size was conducted on a total of 950 public high school students from all governorates. Data on LBP were collected through face-to-face interviews using a structured questionnaire. A 0–10 Numeric Pain Rating …

The Role Of Neck Musculature In Traumatic Brain Injuries In Older Adults: Implications From Sports Medicine, Tyler A. Wood, Steven Morrison, Jacob J. Sosnoff

Rehabilitation Sciences Faculty Publications

Traumatic brain injuries (TBIs) are common and serious injuries to older adults. The majority of TBIs in older adults are sustained when the head impacts the ground or other surface during a fall. While several non-modifiable risk factors have been identified for fall-related TBIs in older adults, there still remains a dearth of knowledge surrounding modifiable risk factors. Thus, this significant knowledge gap warrants an investigation into research across disciplines. The sports medicine literature has examined several modifiable risk factors to prevent a mild form of TBI known as concussion. While this research has identified several risk factors, one particular …
