Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann

Industrial Technology and Packaging

With so many studies being conducted on professional football players regarding concussions and other related brain injuries, it’s amazing that such an important demographic has been missed. While NFL players are just as subjected to serious injuries as anyone else or even more so, it is important to remember that these players are outfitted, in most cases, with top-of-the-line equipment -- especially their helmets. If the focus is shifted to a younger demographic, youth football players in middle school and high school, the equipment is far less advanced and in a vast majority of cases, has been previously used by …

These studies have helped elucidate the neurobiological mechanisms associated with spiritual practices. Such …

Depletion Of Pre-Mrna Splicing Factor Cdc5l Inhibits Mitotic Progression And Triggers Mitotic Catastrophe., R Mu, Y-B Wang, M Wu, Y Yang, W Song, T Li, W-N Zhang, B Tan, A-L Li, N Wang, Q Xia, W-L Gong, Chenguang Wang, T Zhou, N Guo, Z-H Sang, H-Y Li

Department of Cancer Biology Faculty Papers

Disturbing mitotic progression via targeted anti-mitotic therapy is an attractive strategy for cancer treatment. Therefore, the exploration and elucidation of molecular targets and pathways in mitosis are critical for the development of anti-mitotic drugs. Here, we show that cell division cycle 5-like (Cdc5L), a pre-mRNA splicing factor, is a regulator of mitotic progression. Depletion of Cdc5L causes dramatic mitotic arrest, chromosome misalignments and sustained activation of spindle assembly checkpoint, eventually leading to mitotic catastrophe. Moreover, these defects result from severe impairment of kinetochore-microtubule attachment and serious DNA damage. Genome-wide gene expression analysis reveals that Cdc5L modulates the expression of a …

Single Nucleotide Polymorphism Of Srebf-1 Gene Associated With An Increased Risk Of Endometrial Cancer In Chinese Women., Chun-Ping Qiu, Qing-Tao Lv, Samina Dongol, Chenguang Wang, Jie Jiang

Department of Cancer Biology Faculty Papers

AIM: Elevated levels of sterol regulatory element-binding protein-1 (SREBP-1) have been found in endometrial cancer (EC), suggesting that it is essential to the development of EC. Obesity and diabetes have been established as known risk factors of EC, while SREBF-1 gene polymorphisms have also been found to be associated with obesity and type II diabetes. Therefore, we hypothesize that single nucleotide polymorphism (SNP) in SREBF-1 gene may be associated with increased risk of EC.

METHOD: We analyzed the sequence of SREBF-1 in tissue samples from 30 EC cases and 6 benign controls using high throughput method. Based on the primary …

Deep Rna Sequencing Reveals Hidden Features And Dynamics Of Early Gene Transcription In Paramecium Bursaria Chlorella Virus 1, Guillaume Blanc, Michael Mozar, Irina V. Agarkova, James R. Gurnon, Giane Yanai-Balser, Janet M. Rowe, Yuannan Xia, Jean-Jack Riethoven, David D. Dunigan, James L. Van Etten

Nebraska Center for Virology: Faculty Publications

Paramecium bursaria chlorella virus 1 (PBCV-1) is the prototype of the genus Chlorovirus (family Phycodnaviridae) that infects the unicellular, eukaryotic green alga Chlorella variabilis NC64A. The 331-kb PBCV-1 genome contains 416 major open reading frames. A mRNA-seq approach was used to analyze PBCV-1 transcriptomes at 6 progressive times during the first hour of infection. The alignment of 17 million reads to the PBCV-1 genome allowed the construction of single-base transcriptome maps. Significant transcription was detected for a subset of 50 viral genes as soon as 7 min after infection. By 20 min post infection (p.i.), transcripts were detected for …

Myd88-Dependent Immunity To A Natural Model Of Vaccinia Virus Infection Does Not Involve Toll-Like Receptor 2., Michael L Davies, Janet J Sei, Nicholas A Siciliano, Ren-Huan Xu, Felicia Roscoe, Luis J Sigal, Laurence C. Eisenlohr, Christopher C Norbury

Department of Microbiology and Immunology Faculty Papers

UNLABELLED: Although the pattern recognition receptor Toll-like receptor 2 (TLR2) is typically thought to recognize bacterial components, it has been described to alter the induction of both innate and adaptive immunity to a number of viruses, including vaccinia virus (VACV). However, many pathogens that reportedly encode TLR2 agonists may actually be artifactually contaminated during preparation, possibly with cellular debris or merely with molecules that sensitize cells to be activated by authentic TLR2 agonists. In both humans and mice, the most relevant natural route of infection with VACV is through intradermal infection of the skin. Therefore, we examined the requirement for …

Towards A Better Treatment Of Parkinson's Disease, Bradley Darryl Karain

Loma Linda University Electronic Theses, Dissertations & Projects

Current therapies for Parkinson's Disease, the second most common neurodegenerative disorder, do not prevent disease progression, and induce extremely detrimental side-effects. Improving the best current pharmacological therapy, L-DOPA, carries important clinical benefits, partly by reducing the dose-related side-effects which occur after five to ten years of use. Thus the central aim of this proposal is to determine whether low doses of a D2 antagonist may, by selectively blocking the dopamine autoreceptor-mediated feedback inhibition of dopamine neurons, potentiate L-DOPA's effect on individual basal ganglia neurons and its antiparkinsonian effects in Parkinsonian animals. Electrophysiology (extracellular single-cell recording in the globus pallidus) and …

Survivin: Regulation By Yy1 And Role In Pancreatic Cancer Combination Therapy, Nicholas R. Galloway

Loma Linda University Electronic Theses, Dissertations & Projects

Despite significant clinical and basic science advancements, cancer remains a devastating disease that affects people of all ages, races, and background. Survivin, the fourth most common transcript found in cancer cells, is a protein that is thought to be involved in the enhanced proliferation, survival, and metastasis of cancer cells. Therefore understanding how this gene is regulated is potentially of vital importance to improving cancer management and therapy. Our work has identified a novel transcriptional regulator of survivin called Yin Yang 1 (YY1). YY1 is a transcription factor that has been observed to activate some gene promoters and repress others, …

Retinoic Acid Regulation Of Thyroid Hormone Action In Bone Cells, Anjali Babbar

Loma Linda University Electronic Theses, Dissertations & Projects

Retinoic acid and thyroid hormone are known to play key roles in the regulation of endochondral ossification. However, the issue of whether these two hormones interact with each other to regulate bone functions remains to be established. We investigated how thyroid hormone and retinoic acid interact to regulate cells involved in endochondral bone formation. We demonstrate that thyroid hormone treatment stimulates differentiation of ATDC5 chondrocytes and promotes formation of mineralized nodules while retinoic acid treatment at high dose inhibits chondrocyte differentiation and formation of mineralized nodules. Furthermore, thyroid hormone induced mineralized nodule formation is inhibited by co-treatment with retinoic acid …

Vaccines Within Vaccines: The Use Of Adenovirus Types 4 And 7 As Influenza Vaccine Vectors, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Adenovirus Types 4 and 7 (Ad4 and Ad7) are associated with acute respiratory distress (ARD). In order to prevent widespread Ad-associated ARD (Ad-ARD) the United States military immunizes new recruits using a safe and effective lyophilized wildtype Ad4 and Ad7 delivered orally in an enteric-coated capsule. We cloned Ad4 and Ad7 and modified them to express either a GFP-Luciferase (GFPLuc) fusion gene or a centralized influenza H1 hemagglutinin (HA1-con). BALB/c mice were injected with GFPLuc expressing viruses intramuscularly (i.m.) and intranasally (i.n.). Ad4 induced significantly higher luciferase expression levels as compared with Ad7 by both routes. Ad7 transduction was restored …

Xiap Antagonist Embelin Inhibited Proliferation Of Cholangiocarcinoma Cells., Cody J. Wehrkamp, Ashley R. Gutwein, Sathish Kumar Natarajan, Mary Anne Phillippi, Justin L. Mott

Journal Articles: Biochemistry & Molecular Biology

Cholangiocarcinoma cells are dependent on antiapoptotic signaling for survival and resistance to death stimuli. Recent mechanistic studies have revealed that increased cellular expression of the E3 ubiquitin-protein ligase X-linked inhibitor of apoptosis (XIAP) impairs TRAIL- and chemotherapy-induced cytotoxicity, promoting survival of cholangiocarcinoma cells. This study was undertaken to determine if pharmacologic antagonism of XIAP protein was sufficient to sensitize cholangiocarcinoma cells to cell death. We employed malignant cholangiocarcinoma cell lines and used embelin to antagonize XIAP protein. Embelin treatment resulted in decreased XIAP protein levels by 8 hours of treatment with maximal effect at 16 hours in KMCH and Mz-ChA-1 …

Diabetes Mellitus (DM) is currently the fastest growing disease in the world. The prevalence of DM has increased worldwide and is expected to double within 20 years. The UAE is ranked 15^th worldwide, with 18.98% of the UAE population living with diabetes. Six Middle East North Africa (MENA) region countries – Bahrain, Egypt, Kuwait, Oman, Saudi Arabia, and United Arab Emirates (UAE) - are among the world’s 10 highest for prevalence of diabetes and impaired glucose tolerance. This represents a huge cost to society in terms of morbidity and mortality, and economically through lost productivity and cost burden on …

Therapeutic Implications Of Estrogen For Cerebral Vasospasm And Delayed Cerebral Ischemia Induced By Aneurysmal Subarachnoid Hemorrhage., Dale Ding, Robert M Starke, Aaron S Dumont, Gary K Owens, David M Hasan, Nohra Chalouhi, Md, Ricky Medel, Chih-Lung Lin

Department of Neurosurgery Faculty Papers

Cerebral vasospasm (CV) remains the leading cause of delayed morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH). However, increasing evidence supports etiologies of delayed cerebral ischemia (DCI) other than CV. Estrogen, specifically 17 β -estradiol (E2), has potential therapeutic implications for ameliorating the delayed neurological deterioration which follows aneurysmal SAH. We review the causes of CV and DCI and examine the evidence for E2-mediated vasodilation and neuroprotection. E2 potentiates vasodilation by activating endothelial nitric oxide synthase (eNOS), preventing increased inducible NOS (iNOS) activity caused by SAH, and decreasing endothelin-1 production. E2 provides neuroprotection by increasing thioredoxin expression, decreasing c-Jun N-terminal …

Abrogation Of Tnfα Production During Cancer Immunotherapy Is Crucial For Suppressing Side Effects Due To The Systemic Expression Of Il-12, Bibiana Barrios, Natalia S. Baez, Della Reynolds, Pablo Iribarren, Hugo Cejas, Howard A. Young, Maria Cecilia Rodriguez-Galan

United States Public Health Resources

For more than a decade, the cytokine interleukin-12 (IL-12) has been utilized, either alone or in combination with other drugs, as a treatment for cancer. The numerous anti-tumor properties of IL-12 still generate interest in the clinical use of this cytokine, even though it has demonstrated toxicity when administrated systemically. As an approach to overcome this toxicity, numerous laboratories have attempted to induce IL-12 expression at the site of the tumor. However for tumors that are difficult to remove surgically or for the treatment of disseminated metastases, systemic expression of this cytokine still remains as the most efficient method of …

Systematic Analysis Of A Xenograft Mice Model For Kshv+ Primary Effusion Lymphoma (Pel), Lu Dai, Jimena Trillo-Tinoco, Lihua Bai, Baoli Kang, Zengguang Xu, Xiaofei Wen, Luis Del Valle, Zhiqiang Qin

School of Medicine Faculty Publications

Kaposi's sarcoma-associated herpesvirus is the causative agent of primary effusion lymphoma (PEL), which arises preferentially in the setting of infection with human immunodeficiency virus (HIV). Even with standard cytotoxic chemotherapy, PEL continues to cause high mortality rates, requiring the development of novel therapeutic strategies. PEL xenograft models employing immunodeficient mice have been used to study the in vivo effects of a variety of therapeutic approaches. However, it remains unclear whether these xenograft models entirely reflect clinical presentations of KSHV(+) PEL, especially given the recent description of extracavitary solid tumor variants arising in patients. In addition, effusion and solid tumor cells …

Nuclear Interaction Between Adr-Induced P65 And P53 Mediates Cardiac Injury In Inos (−/−) Mice, Marsha P. Cole, Jitbanjong Tangpong, Terry D. Oberley, Luksana Chaiswing, Kinsley K. Kiningham, Daret K. St. Clair

Toxicology and Cancer Biology Faculty Publications

Adriamycin (ADR) treatment causes an imbalance in the levels of nitric oxide (^•NO) and superoxide (O₂^•−) production leading to cardiac injury. Previously we demonstrated that mice lacking inducible nitric oxide synthase (iNOS) have increased oxidative stress and mitochondrial injury. The molecular events leading to increased mitochondrial injury in iNOS deficient mice is unknown. ADR in the absence of iNOS preferentially activates a proapoptotic pathway without a concurrent increase in prosurvival pathways. Treatment with ADR leads to an increase in DNA binding activity of nuclear factor kappa B (NFκB) and p53 in wildtype mice. Following ADR …

A Modified Generalized Fisher Method For Combining Probabilities From Dependent Tests., Hongying Dai, J Steven Leeder, Yuehua Cui

Manuscripts, Articles, Book Chapters and Other Papers

Rapid developments in molecular technology have yielded a large amount of high throughput genetic data to understand the mechanism for complex traits. The increase of genetic variants requires hundreds and thousands of statistical tests to be performed simultaneously in analysis, which poses a challenge to control the overall Type I error rate. Combining p-values from multiple hypothesis testing has shown promise for aggregating effects in high-dimensional genetic data analysis. Several p-value combining methods have been developed and applied to genetic data; see Dai et al. (2012b) for a comprehensive review. However, there is a lack of investigations conducted for dependent …

B Cell Tolerance In Health And Disease, Murali Gururajan, Vishal J. Sindhava, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

B lymphocyte receptors are generated randomly during the bone marrow developmental phase of B cells. Hence, the B cell repertoire consists of both self and foreign antigen specificities necessitating specific tolerance mechanisms to eliminate self-reactive B cells. This review summarizes the major mechanisms of B cell tolerance, which include clonal deletion, anergy and receptor editing. In the bone marrow presentation of antigen in membrane bound form is more effective than soluble form and the role of dendritic cells in this process is discussed. Toll like receptor derived signals affect activation of B cells by certain ligands such as nucleic acids …

Ube3a Role In Synaptic Plasticity And Neurodevelopmental Disorders.The Lessons From Angelman Syndrome., Irina Filonova

USF Tampa Graduate Theses and Dissertations

Angelman Syndrome (AS) is a severe neurodevelopmental disorder that affects 1:12000 newborns. It is characterized by mental retardation, delayed major motor and cognitive milestones, seizures, absence of speech and excessive laughter. The majority of AS cases arise from deletions or mutations of UBE3A gene located on the chromosome 15q11-13. UBE3A codes for E3-ubiquitin ligase that target specific proteins for degradation. To date, a wide variety of Ube3a substrates has been identified. The accumulation of Ube3a-dependent proteins and their effect on the multitude of signal transduction pathways are` considered the main cause of the AS pathology. While the majority of research …

Substance P Differentially Modulates Firing Rate Of Solitary Complex (Sc) Neurons From Control And Chronic Hypoxia-Adapted Adult Rats, Nicole L. Nichols, Frank L. Powell, Jay B. Dean, Robert W. Putnam

Neuroscience, Cell Biology & Physiology Faculty Publications

NK1 receptors, which bind substance P, are present in the majority of brainstem regions that contain CO₂/H⁺-sensitive neurons that play a role in central chemosensitivity. However, the effect of substance P on the chemosensitive response of neurons from these regions has not been studied. Hypoxia increases substance P release from peripheral afferents that terminate in the caudal nucleus tractus solitarius (NTS). Here we studied the effect of substance P on the chemosensitive responses of solitary complex (SC: NTS and dorsal motor nucleus) neurons from control and chronic hypoxia-adapted (CHx) adult rats. We simultaneously measured intracellular pH …

Complexity Of Interferon-Γ Interactions With Hsv-1, Nancy J. Bigley

Neuroscience, Cell Biology & Physiology Faculty Publications

The intricacies involving the role of interferon-gamma (IFN-γ) in herpesvirus infection and persistence are complex. Herpes simplex virus type 1 (HSV-1) uses a variety of receptors to enter cells and is transported to and from the host cell nucleus over the microtubule railroad via retrograde and anterograde transport. IFN-γ exerts dual but conflicting effects on microtubule organization. IFN-γ stimulates production of suppressors of cytokine signaling 1 and 3 (SOCS1 and SOCS3), which are involved in microtubule stability and are negative regulators of IFN-γ signaling when overexpressed. IFN-γ also interferes with the correct assembly of microtubules causing them to undergo severe …

Anakinra And Related Drugs Targeting Interleukin-1 In The Treatment Of Cryopyrin-Associated Periodic Syndromes, Inessa Bachove, Christopher Chang

Department of Pediatrics Faculty Papers

Anakinra is an interleukin (IL) receptor antagonist that works by blocking the biological activity of IL-1 by competitively inhibiting binding of IL-1 to the type 1 interleukin receptor. IL-1 production is induced in response to inflammatory stimuli and mediates various physiological mechanisms, including inflammation and immunological reactions. Patients with neonatal onset multisystem inflammatory disease (NOMID) produce excess IL-1β, a major proinflammatory cytokine that regulates innate immune responses. Anakinra binds competitively and this results in a rapid reduction in disease severity. NOMID, also known as chronic infantile neurologic, cutaneous, articular syndrome, is the most severe clinical phenotype in the spectrum of …

A Melanin-Independent Interaction Between Mc1r And Met Signalling Pathways Is Required For Hgf-Dependent Melanoma, Agnieszka Wolnicka-Głubisz, Faith M. Strickland, Albert Wielgus, Miriam Anver, Glenn Merlino, Edward C. De Fabo, Frances P. Noonan

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Melanocortin 1 receptor (MC1R) signaling stimulates black eumelanin production through a cAMP-dependent pathway. MC1R polymorphisms can impair this process, resulting in a predominance of red phaeomelanin. The red hair, fair skin and UV sensitive phenotype is a well-described melanoma risk factor. MC1R polymorphisms also confer melanoma risk independent of pigment. We investigated the effect of Mc1r deficiency in a mouse model of UV-induced melanoma. C57BL/6-Mc1r+/+-HGF transgenic mice have a characteristic hyperpigmented black phenotype with extra-follicular dermal melanocytes located at the dermal/epidermal junction. UVB induces melanoma, independent of melanin pigmentation, but UVA-induced and spontaneous melanomas are dependent on black eumelanin. We …

Inflammation Enhances Il-2 Driven Differentiation Of Cytolytic Cd4 T Cells, Aspen M. Workman, Ashley K. Jacobs, Alexander J. Vogel, Shirley Condon, Deborah M. Brown

Nebraska Center for Virology: Faculty Publications

Cytolytic CD4 T cells (CD4 CTL) have been identified in vivo in response to viral infections; however, the factors necessary for driving the cytolytic phenotype have not been fully elucidated. Our previously published work suggests IL-2 may be the master regulator of perforin-mediated cytotoxicity in CD4 effectors. To further dissect the role of IL-2 in CD4 CTL generation, T cell receptor transgenic mice deficient in the ability to produce IL-2 or the high affinity IL-2 receptor (IL-2Rα, CD25) were used. Increasing concentrations of IL-2 were necessary to drive perforin (Prf) expression and maximal cytotoxicity. Granzyme B (GrB) expression and killing …

The Differential Interferon Responses Of Two Strains Of Stat1-Deficient Mice Do Not Alter Susceptibility To Hsv-1 And Vsv In Vivo, Sarah Katzenell, Yufei Chen, Zachary M. Parker, David A. Leib

Dartmouth Scholarship

Stat1 is a pivotal transcription factor for generation of the interferon (IFN)-dependent antiviral response. Two Stat1 knockout mouse lines have been previously generated, one deleted the N-terminal domain (ΔNTD) and one in the DNA-binding domain (ΔDBD). These widely-used strains are assumed interchangeable, and both are highly susceptible to various pathogens. In this study, primary cells derived from ΔNTD mice were shown to be significantly more responsive to IFN, and established an antiviral state with greater efficiency than cells derived from ΔDBD mice, following infection with vesicular stomatitis virus and herpes simplex virus type-1. Also, while mice from both strains succumbed …

Quantitative Evaluation Of Microglial Activation And Vascularization In Suicide, Tatiana Pavlovna Schnieder

Dissertations, Theses, and Capstone Projects

Accumulated evidence points to immunological factors in psychiatric disorders. In a variety of chronic neurological disorders, exacerbation is associated with inflammation and a loss of integrity of the blood-brain barrier. Microglia, the principal brain immunological cells in the healthy state, respond to changes in the internal environment of the brain through a sequence of activated states. This study compared microglial phenotypes in the white matter of autopsy brains from 11 suicide victims and 25 subjects who died involuntarily. Both groups included cases with and without major psychiatric disorders, which were determined by PA interviews. Cases were matched for sex, age, …

Fgf-2 Induces Neuronal Death Through Upregulation Of System Xc-, Xiaoqian Liu, Rebecca Albano, Doug Lobner

Biomedical Sciences Faculty Research and Publications

The cystine/glutamate antiporter (system xc-) transports cystine into cell in exchange for glutamate. Fibroblast growth factor-2 (FGF-2) upregulates system xc- selectively on astrocytes, which leads to increased cystine uptake, the substrate for glutathione production, and increased glutamate release. While increased intracellular glutathione can limit oxidative stress, the increased glutamate release can potentially lead to excitotoxicity to neurons. To test this hypothesis, mixed neuronal and glial cortical cultures were treated with FGF-2. Treatment with FGF-2 for 48 h caused a significant neuronal death in these cultures. Cell death was not observed in neuronal-enriched cultures, or astrocyte-enriched …

Repair Of Oxidative Dna Damage And Cancer: Recent Progress In Dna Base Excision Repair, Timothy L. Scott, Suganya Rangaswamy, Christina A. Wicker, Tadahide Izumi

Toxicology and Cancer Biology Faculty Publications

SIGNIFICANCE: Reactive oxygen species (ROS) are generated by exogenous and environmental genotoxins, but also arise from mitochondria as byproducts of respiration in the body. ROS generate DNA damage of which pathological consequence, including cancer is well established. Research efforts are intense to understand the mechanism of DNA base excision repair, the primary mechanism to protect cells from genotoxicity caused by ROS.

RECENT ADVANCES: In addition to the notion that oxidative DNA damage causes transformation of cells, recent studies have revealed how the mitochondrial deficiencies and ROS generation alter cell growth during the cancer transformation.

CRITICAL ISSUES: The emphasis of this …
