Differential Regulation Of Immature Articular Cartilage Compressive Moduli And Poisson’S Ratios By In Vitro Stimulation With Igf-1 And Tgf-Β1, Gregory M. Williams, Kristin J. Dills, Christian R. Flores, Michael E. Stender, Kevin M. Stewart, Lauren M. Nelson, Albert C. Chen, Koichi Masuda, Scott J. Hazelwood, Stephen M. Klisch, Robert L. Sah

Mechanical Engineering

Mechanisms of articular cartilage growth and maturation have been elucidated by studying composition-function dynamics during in vivo development and in vitro culture with stimuli such as insulin-like growth factor-1 (IGF-1) and transforming growth factor-beta 1 (TGF-β1). This study tested the hypothesis that IGF-1 and TGF-β1 regulate immature cartilage compressive moduli and Poisson’s ratios in a manner consistent with known effects on tensile properties. Bovine calf articular cartilage from superficial-articular (S) and middle-growth (M) regions were analyzed fresh or following culture in medium with IGF-1 or TGF-β1. Mechanical properties in confined (CC) and unconfined (UCC) compression, cartilage matrix composition, and explant …

Integrating Concepts And Technologies To Advance The Study Of Bird Migration, W. Douglas Robinson, Melissa Bowlin, Isabelle Bisson, Judy Shamoun-Barnes, Kasper Thorup, Robert H. Diehl, Thomas H. Kunz, Sarah Mabey, David W. Winkler

Faculty Publications

Recent technological innovation has opened new avenues in migration research - for instance, by allowing individual migratory animals to be followed over great distances and long periods of time, as well as by recording physiological information. Here, we focus on how technology - specifically applied to bird migration - has advanced our knowledge of migratory connectivity, and the behavior, demography, ecology, and physiology of migrants. Anticipating the invention of new and smaller tracking devices, in addition to the ways that technologies may be combined to measure and record the behavior of migratory animals, we also summarize major conceptual questions that …

Limitations On Simultaneity In Sign Language, Donna Jo Napoli, R. Sutton-Spence

Linguistics Faculty Works

When we converse, information is often conveyed in multiple ways. For those using spoken language, we have, besides the vocal tract, nonverbal articulators as well, including eye gaze (Hanna & Brennan 2007), gesture (Kendon 2004), facial expression (Busso & Narayanan 2007), lip pointing (Sherzer 1983), and puffed cheeks (Sherzer 1993). Likewise, for those using a sign language, we have, besides the hands, nonmanual articulators as well, including facial expressions, eye gaze, mouth, and body posture (Baker & Padden 1978). In this short report we investigate how much information can be simultaneously expressed in sign language (by counting ‘propositions’) and conclude …

Macroevolutionary Patterns In The Evolutionary Radiation Of Archosaurs (Tetrapoda: Diapsida), S. L. Brusatte, M. J. Benton, G. T. Lloyd, M. Ruta, Steve C. Wang

Mathematics & Statistics Faculty Works

The rise of archosaurs during the Triassic and Early Jurassic has been treated as a classic example of an evolutionary radiation in the fossil record. This paper reviews published studies and provides new data on archosaur lineage origination, diversity and lineage evolution, morphological disparity, rates of morphological character change, and faunal abundance during the Triassic–Early Jurassic. The fundamental archosaur lineages originated early in the Triassic, in concert with the highest rates of character change. Disparity and diversity peaked later, during the Norian, but the most significant increase in disparity occurred before maximum diversity. Archosaurs were rare components of Early–Middle Triassic …

Conidia But Not Yeast Cells Of The Fungal Pathogen Histoplasma Capsulatum Trigger A Type I Interferon Innate Immune Response In Murine Macrophages, Diane O. Inglis, Charlotte A. Berkes, Davina R. Hocking Murray, Anita Sil

Biology Faculty Publications

Histoplasma capsulatum is the most common cause of fungal respiratory infections and can lead to progressive disseminated infections, particularly in immunocompromised patients. Infection occurs upon inhalation of the aerosolized spores, known as conidia. Once inside the host, conidia are phagocytosed by alveolar macrophages. The conidia subsequently germinate and produce a budding yeast-like form that colonizes host macrophages and can disseminate throughout host organs and tissues. Even though conidia are the predominant infectious particle for H. capsulatum and are the first cell type encountered by the host during infection, very little is known at a molecular level about conidia or about …

Repression Of Wnt Signaling By A Fer-Type Nonreceptor Tyrosine Kinase, Aaron P. Putzke

Biology Faculty Scholarship

The Wnt signaling pathway must be properly modulated to ensure an appropriate output: pathological conditions result from either insufficient or excessive levels of Wnt signal. For example, hyperactivation of the Wnt pathway is associated with various cancers and subnormal Wnt signaling can lead to increased invasiveness of tumor cells. We found that the Caenorhabditis elegans ortholog of the Fer nonreceptor tyrosine kinase, FRK-1, limits Wnt signaling by preventing the adhesion complex-associated β-catenin, HMP-2, from participating in Wnt-dependent specification of the endoderm during embryogenesis. Removal of FRK-1 function results in relocalization of HMP-2 to the nucleus of epidermal cells, and allows …

Quantification Of Localized Brain Iron Sources Using Magnetic Resonance Phase, Grant Alexander Mcauley

Loma Linda University Electronic Theses, Dissertations & Projects

Brain microbleeds (BMB), often present in cerebrovascular and neurodegenerative diseases and neurotrauma, are associated with both chronic and acute illness of significant social and economic impact. Because BMB present a source of potentially cyctotoxic iron to the brain proportional to the amount of extravasated blood, non-invasive quantification of this iron pool is potentially valuable both to assess tissue risk and as a biomarker to monitor disease progression, treatment efficacy, and inform treatment. Past efforts to quantify brain iron have focused on distributed (e.g., anatomical) brain regions. However, BMB represent localized sources of iron deposition. In addition, conventional "magnitude" MR images …

Experimental Models Of Brain Hemorrhage Using Clostridial Collagenase, Tim Lekic

Loma Linda University Electronic Theses, Dissertations & Projects

Stroke is the third leading cause of death and is the leading cause of disability in the United States, and the most severe form is known as intracerebral hemorrhage, which is bleeding into the brain. The goal of this study is to establish novel animal models to buildup foundations for translational research of intracerebral hemorrhage. We, for the first time, established four animal models, including cerebellum hemorrhage, pontine hemorrhage, neonatal matrix hemorrhage and maternal postpartum hemorrhage. Those models are established according to intracerebral hemorrhage patient subpopulations, and characterized the neurobehavioral and morphological outcomes. These studies have established the requisite for …

Splice Factor Sfrs6: Regulation By P53 And Effect On Il-24 Splicing, Erin L. Schmidt

Loma Linda University Electronic Theses, Dissertations & Projects

Alternative splicing of RNA transcripts is emerging as a major mechanism for expanding the proteome. Splice pattern changes are found in numerous diseases and cancers, indicating the importance of tight control over this process. While the mechanism of splicing has been described in detail, it is less clear how a cell is able to modify its splicing patterns in response to different conditions. Our lab previously demonstrated that DNA damage can induce SFRS6, the gene coding for splicing factor SRp55, thereby leading to changes in the splicing patterns of several target genes related to survival and apoptosis. We also …

Assessing The Prevalence Of Inadequate Nutrient Intake Among Vegetarians And Non-Vegetarians Using The Estimated Average Requirement : Results From The Adventist Health Study-2 Calibration Study, Choon Chew Teo

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Studies have shown that vegetarians have lower risk of chronic diseases and longer lifespan. Yet when mean intake of vegetarians was compared with the Recommended Dietary Allowance (RDA), it was reported that vegetarians were inadequate in certain nutrients. With the recent establishment of the Estimated Average Requirement (EAR), the new reference standard for assessing adequacy of population intakes, nutrient adequacy of the vegetarian diet should now be reassessed.

Daily number of servings for each food group of the food guides have usually been theoretically computed based on intakes suggested in menus or cookbooks. We attempted to use the actual …

Comparison Of Non-Surgical And Surgical Endodontic Retreatment: A Systematic Review, Robert Corr

Loma Linda University Electronic Theses, Dissertations & Projects

Primary root canal therapy has been shown to be a predictable procedure with a high degree of success ^1-4, however failures can occur after treatment. Treatment options for the preservation of teeth that have had previous endodontic treatment but demonstrate persistent disease include non-surgical (orthograde) or surgical (retrograde) endodontic retreatment, assuming the tooth is restorable, periodontally sound, and the patient desires to retain the tooth. The purpose of this study was to conduct a systematic review of the current available evidence to compare the clinical and radiographic outcomes of nonsurgical with those of surgical endodontic retreatment. Methodology began with …

Correlating The Slope Of The Vomer With Cephalometric Vectors Of Facial Growth, Ryan Michael Pulfer

Loma Linda University Electronic Theses, Dissertations & Projects

It is important for orthodontists to have a basic understanding of the growth and development of the face. Scott's nasal septal cartilage theory proposes that the cartilage of the nasal septum proliferates along the anterior slope of the vomer bone by interstitial growth, simultaneously pulling and displacing the maxilla downward and forward. It is therefore logical to conclude that the vector of nasomaxillary growth has a geometric correlation with the anterior slope of the vomer bone.

There are no published studies comparing either the anterior or posterior slope of the vomer with any lateral cephalometric landmarks, the vectors of nasomaxillary …

Microct Study Of Critical-Sized Defects Restored With A New Rhbmp-2 Carrier, Joanne S. Kim

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Regenerating bone in critical-sized maxillofacial osseous defects remains a challenge. The utilization of recombinant human bone morphogenetic protein-2 (rhBMP-2) to form new bone has been shown to be a promising alternative to autogenous bone grafts, and the development of a carrier matrix to effectively deliver the rhBMP-2 has been identified as the critical factor necessary for the successful clinical application of rhBMP-2. The objective of this study was to perform a microCT analysis to examine the density of reconstructed bone using different rhBMP-2 carriers in critical-sized defects.

Material and Methods: Critical-sized defects (approximately 2.5 cm) were created in the …

Post-Traumatic Stress Disorder-Like Symptomatology In Pediatric Intensivists, Dina Gabriella Cuervo

Loma Linda University Electronic Theses, Dissertations & Projects

Helping professionals, such as social workers, emergency first responders and medical personnel are susceptible to traumatic stress reactions through indirect exposure to trauma via the traumatized population whom they serve. This phenomenon, known as secondary traumatic stress (STS), mimicking the symptoms of posttraumatic stress disorder, can have an impact on a provider’s work with his/her patient or have longer-term effects such as deciding to leave the profession. This study found that physicians’ level of job stress was the strongest predictor of STS and that this relationship was also influenced by resiliency, ego strength and attachment style. Individuals with higher levels …

Diagnosing And Treating Adhd: Discipline Differences, Lisa Marie Lliteras

Loma Linda University Electronic Theses, Dissertations & Projects

According to Barkley (2005), attention deficit hyperactivity disorder (ADHD) is one of the most common reasons children are referred to mental health workers in the United States and is now one of the most prevalent psychiatric disorders associated with childhood. The diagnostic criteria and labels for ADHD have changed over the last several decades, and with each change the prevalence rate for ADHD has increased (Wolraich & Baumgaertel, 1997). This increase in the prevalence of ADHD has led to a need for clinicians from different disciplines to assess and treat ADHD. As such, several guidelines from professional associations have been …

Some Realism About Punishment Naturalism (With Responses), Donald Braman, Dan M. Kahan, David A. Hoffman, Paul H. Robinson

University of Chicago Law Review

In this Article, we critique the increasingly prominent claims of Punishment Naturalism—the notion that highly nuanced intuitions about most forms of crime and punishment are broadly shared, and that this agreement is best explained by a particular form of evolutionary psychology. While the core claims of Punishment Naturalism are deeply attractive and intuitive, they are contradicted by a broad array of studies and depend on a number of logical missteps. The most obvious shortcoming of Punishment Naturalism is that it ignores empirical research demonstrating deep disagreements over what constitutes a wrongful act and just how wrongful a given act should …

The Global Impact Of Sutures Assessed In A Finite Element Model Of A Macaque Cranium, Qian Wang, Amanda L. Smith, David S. Strait, Barth Wright, Brian G. Richmond, Ian R. Grosse, Craig Byron, Uriel Zapata

Faculty and Staff Publications

The biomechanical significance of cranial sutures in primates is an open question because their global impact is unclear, and their material properties are difficult to measure. In this study, eight suture-bone functional units representing eight facial sutures were created in a finite element model of a monkey cranium. All the sutures were assumed to have identical isotropic linear elastic material behavior that varied in different modeling experiments, representing either fused or unfused sutures. The values of elastic moduli employed in these trials ranged over several orders of magnitude. Each model was evaluated under incisor, premolar, and molar biting conditions. Results …
