Efficacy Of Female Rat Models In Translational Cardiovascular Aging Research, Kevin M. Rice, J. C. Fannin, C. Gillette, Eric Blough

Pharmaceutical Science and Research

Cardiovascular disease is the leading cause of death in women in the United States. Aging is a primary risk factor for the development of cardiovascular disease as well as cardiovascular-related morbidity and mortality. Aging is a universal process that all humans undergo; however, research in aging is limited by cost and time constraints. Therefore, most research in aging has been done in primates and rodents; however it is unknown how well the effects of aging in rat models translate into humans. To compound the complication of aging gender has also been indicated as a risk factor for various cardiovascular diseases. …

During the past decades, anticancer immunotherapy has evolved from a promising therapeutic option to a robust clinical reality. Many immunotherapeutic regimens are now approved by the US Food and Drug Administration and the European Medicines Agency for use in cancer patients, and many others are being investigated as standalone therapeutic interventions or combined with conventional treatments in clinical studies. Immunotherapies may be subdivided into "passive" and "active" based on their ability to engage the host immune system against cancer. Since the anticancer activity of most passive immunotherapeutics (including tumor-targeting monoclonal antibodies) also relies on the host immune system, this classification …

Can Acute Dermal Systemic Toxicity Tests Be Replaced With Oral Tests? A Comparison Of Route-Specific Systemic Toxicity And Hazard Classifications Under The Globally Harmonized System Of Classification And Labelling Of Chemicals (Ghs), Nigel P. Moore, David J. Andrew, Donald L. Bjerke, Stuart Creton, David Dreher, Thomas Holmes, Pilar Prieto, Troy Seidle, Tim G. Rowan

Troy Seidle, PhD

Acute systemic toxicity data (LD50 values) and hazard classifications derived in the rat following oral administration and dermal application have been analysed to examine whether or not orally-derived hazard classification or LD50 values can be used to determine dermal hazard classification. Comparing the oral and dermal classifications for 335 substances derived from oral and dermal LD50 values respectively revealed 17% concordance, and indicated that 7% of substances would be classified less severely while 76% would be classified more severely if oral classifications were applied directly to the dermal route. In contrast, applying the oral LD50 values within the dermal classification …

A Modular One-Generation Reproduction Study As A Flexible Testing System For Regulatory Safety Assessment, Richard Vogel, Troy Seidle, Horst Spielmann

Troy Seidle, PhD

The European Union’s Registration, Evaluation and Authorisation of Chemicals (REACH) legislation mandates testing and evaluation of approximately 30,000 existing substances within a short period of time, beginning with the most widely used “high production volume” (HPV) chemicals. REACH testing requirements for the roughly 3000 HPV chemicals specify three separate tests for reproductive toxicity: two developmental toxicity studies on different animal species (OECD Test Guideline 414) and a two-generation reproduction toxicity study (OECD TG 416). These studies are highly costly in both economic and animal welfare terms. OECD TG 416 is a fertility study intended to evaluate reproductive performance of animals …

Incorporating Information From Neuroscience And Endocrinology Regarding Sexual Orientation Into Social Work Education, Jill Littrell

Moreover, the brains of gay men are similar to heterosexual females whereas the brains of lesbians are similar to heterosexual males. Neuroscience research supporting these postulates is reviewed. The gestational processes that might explain the differences in brain structure and function corresponding with gender are reviewed. Following a discussion of the physiological bases for sexual orientation, a discussion of the physiological bases for the expression of gender related traits and a discussion of factors contributing to sexual identity are provided. Throughout the article, alternative ways to think about gender are …

Metabolic Correlates In Spinal Cord Compression Measured By Magnetic Resonance Spectroscopy In The Motor And Sensory Cortices, Sandy Goncalves

Electronic Thesis and Dissertation Repository

Surgical outcome for patients suffering from cervical myelopathy (CM) is unpredictable with varying motor and sensory symptom recovery. Previous in-vivo magnetic resonance spectroscopy (MRS) studies of patients surgically treated for CM have demonstrated decreased N-acetylaspartate (NAA)/creatine levels in the motor cortex indicating reduced neuronal function. The goal of this thesis was to determine whether absolute NAA changes in the motor and sensory cortices mirror the pattern of motor and sensory functional change observed in patients post surgical treatment.

MRS data were acquired on a 3.0 Tesla Siemens MRI along with clinical outcome measures at baseline, 6-weeks and 6-months post-surgery. …

Human ovarian cancer is diagnosed in the late, metastatic stages but the underlying mechanisms remain poorly understood. We report a surprising functional link between CD151-α3β1 integrin complexes and the malignancy of serous-type ovarian cancer. Analyses of clinical specimens indicate that CD151 expression is significantly reduced or diminished in 90% of metastatic lesions, while it remains detectable in 58% of primary tumors. These observations suggest a putative tumor-suppressing role of CD151 in ovarian cancer. Indeed, our analyses show that knocking down CD151 or α3 integrin enhances tumor cell proliferation, growth and ascites production in nude mice. These changes are accompanied by …

Mcp-1 In Colorectal Cancer: Benefits Of Exercise, Jamie Lee Mcclellan

Theses and Dissertations

The etiology of colon cancer is a complex phenomenon that involves both genetic and environmental factors. However, only about 20% have a familial basis with the largest fraction being attributed to environmental causes that can lead to chronic inflammation. Tumors associated macrophages drive the pro-inflammatory response in the tumor micro-environment and are associated with poor prognosis in certain cancers. Monocyte chemoattractant protein 1 (MCP-1) is thought to be the most important chemokine for recruitment of macrophages to the tumor microenvironment. In chapter 1, we examined the timing and magnitude of the intestinal inflammatory cytokine response in relation to tumorigenesis in …

Marine Population Connectivity: Range Boundaries And Climate Change, Rhiannon Leigh Rognstad

Theses and Dissertations

Population connectivity, particularly in open systems, is an important metric for understanding population-level processes on both ecological and evolutionary timescales. In coastal marine systems, adults are typically sedentary and dispersal occurs primarily during a larval stage when individuals are transported in ocean currents. Because coastal marine populations exist as networks of interconnected subpopulations, variation in the magnitude and extent of population connectivity can have profound effects on population dynamics and species distribution limits. Connectivity is a complex process, affected by a multitude of factors, including adult inputs and physical dispersal, which operate at multiple scales and may interact. This dissertation …

Mouse Models Of Intervertebral Disc Development, Degeneration And Mechanical Loading, Matthew R. Mccann

Electronic Thesis and Dissertation Repository

Intervertebral disc (IVD) degeneration is a complex and multi-factorial process that is influenced by aging, genetic predispositions and environmental influences, such as altered mechanical loading. While recent studies have begun to characterize changes in the IVD associated with degeneration, the underlying etiology remains elusive. It is thought that the loss of notochord cells from the nucleus pulposus (NP) is one initiating factor contributing to the cascade of disc degeneration. However, questions remain about the function of notochord cells within the disc, including their capacity as tissue specific progenitor cells for the nucleus pulposus. We have demonstrated, with the use of …

Modulation Of The Cardiomyocyte Hypertrophic Responses To Endothelin-1 By Adipocytes, Suresh Chandra Bairwa

Electronic Thesis and Dissertation Repository

Leptin and adiponectin are the adipokines that are shown to exert pro-hypertrophic and anti-hypertrophic effects respectively, in cardiomyocytes. We sought to determine the direct interaction between the adipocytes and cardiomyocytes during endothelin-1 (ET-1)-induced cardiomyocyte hypertrophy and determine the role of leptin and adiponectin.

The adipose tissue conditioned medium (ACM) inhibited the ET-1-induced hypertrophy in a concentration-dependent manner and this anti-hypertrophic effect was more potent or reversed in the presence of leptin receptor antagonist (LRA; 0.1 nM) or adiponectin receptor-1 antibody (ARA; 100 ng/mL), respectively. ACM from heart failure rats induced by coronary artery ligation or obese rats did not mitigate …

Medical Biophysics Publications

BACKGROUND: Advances in MRI have the potential to improve surgical treatment of epilepsy through improved identification and delineation of lesions. However, validation is currently needed to investigate histopathological correlates of these new imaging techniques. The purpose of this work is to develop and evaluate a protocol for deformable image registration of in-vivo to ex-vivo resected brain specimen MRI. This protocol, in conjunction with our previous work on ex-vivo to histology registration, completes a registration pipeline for histology to in-vivo MRI, enabling voxel-based validation of novel and existing MRI techniques with histopathology.

NEW METHOD: A combination of image-based and landmark-based 3D …

Loss Of Thiol Repair Systems In Human Cataractous Lenses, Min Wei, Kui-Yi Xing, Yin-Chuan Fan, Teodosio Libondi, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

PURPOSE. The purpose of this study was to investigate the thiol repair systems of thioltransferase (TTase) and thioredoxin (Trx) and oxidation-damaged proteins in human cataractous lenses.

METHODS. Cataractous lenses in humans (57–85 years of age) were classified into cortical, nuclear, mixed, mature, and hypermature cataract types by using a lens opacity classification system, and were obtained by extracapsular cataract extraction (ECCE) procedure. Cortical and nuclear cataracts were grouped by decreasing order of visual acuity into optical chart reading (R), counting fingers (CF), hand motion (HM), and light perception (LP). ECCE lens homogenate was analyzed for glutathione (GSH) level and enzyme …

Oligomerization, Conformational Stability And Thermal Unfolding Of Harpin, Hrpzpss And Its Hypersensitive Response-Inducing C-Terminal Fragment, C-214-Hrpzpss., Pradip K Tarafdar, Lakshmi Vasudev Vedantam, Rajeshwer S Sankhala, Pallinti Purushotham, Appa Rao Podile, Musti J Swamy

Department of Biochemistry and Molecular Biology Faculty Papers

HrpZ-a harpin from Pseudomonas syringae-is a highly thermostable protein that exhibits multifunctional abilities e.g., it elicits hypersensitive response (HR), enhances plant growth, acts as a virulence factor, and forms pores in plant plasma membranes as well as artificial membranes. However, the molecular mechanism of its biological activity and high thermal stability remained poorly understood. HR inducing abilities of non-overlapping short deletion mutants of harpins put further constraints on the ability to establish structure-activity relationships. We characterized HrpZPss from Pseudomonas syringae pv. syringae and its HR inducing C-terminal fragment with 214 amino acids (C-214-HrpZPss) using calorimetric, spectroscopic and microscopic approaches. Both …

P53 And Cancer-Associated Sialylated Glygans Are Surrogate Markers Of Cancerization Of The Bladder Associated With Schistosoma Haematobium Infection, Julio Santos, Elisabete Fernandes, Jose Alexandre Ferreira, Luis Lima, Ana Tavares, Andreia Peixoto, Beatriz Parreira, Jose Manuel Correia Da Costa, Paul J. Brindley, Carlos Lopes, Lucio L. Santos

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Bladder cancer is a significant health problem in rural areas of Africa and the Middle East where Schistosoma haematobium is prevalent, supporting an association between malignant transformation and infection by this blood fluke. Nevertheless, the molecular mechanisms linking these events are poorly understood. Bladder cancers in infected populations are generally diagnosed at a late stage since there is a lack of non-invasive diagnostic tools, hence enforcing the need for early carcinogenesis markers.

Methodology/Principal Findings

Forty-three formalin-fixed paraffin-embedded bladder biopsies of S. haematobium-infected patients, consisting of bladder tumours, tumour adjacent mucosa and pre-malignant/malignant urothelial lesions, were screened for bladder …

Expression Of Suppressor Of Cytokine Signaling 1 (Socs1) Impairs Viral Clearance And Exacerbates Lung Injury During Influenza Infection., Keer Sun, Sharon Salmon, Vijaya Kumar Yajjala, Christopher Bauer, Dennis W. Metzger

Journal Articles: Pathology and Microbiology

Suppressor of cytokine signaling (SOCS) proteins are inducible feedback inhibitors of cytokine signaling. SOCS1-/- mice die within three weeks postnatally due to IFN-γ-induced hyperinflammation. Since it is well established that IFN-γ is dispensable for protection against influenza infection, we generated SOCS1-/-IFN-γ-/- mice to determine whether SOCS1 regulates antiviral immunity in vivo. Here we show that SOCS1-/-IFN-γ-/- mice exhibited significantly enhanced resistance to influenza infection, as evidenced by improved viral clearance, attenuated acute lung damage, and consequently increased survival rates compared to either IFN-γ-/- or WT animals. Enhanced viral clearance in SOCS1-/-IFN-γ-/- mice coincided with a rapid onset of adaptive immune …

Ifn-Γ Causes Aplastic Anemia By Altering Hematopoietic Stem/Progenitor Cell Composition And Disrupting Lineage Differentiation, Fan Ching Lin, Megan Karwan, Bahara Saleh, Deborah L. Hodge, Tim Chan, Kimberly C. Boelte, Jonathan R. Keller, Howard A. Young

Public Health Resources

Aplastic anemia (AA) is characterized by hypocellular marrow and peripheral pancytopenia. Because interferon gamma (IFN-γ) can be detected in peripheral blood mononuclear cells of AA patients, it has been hypothesized that autoreactive T lymphocytes may be involved in destroying the hematopoietic stem cells. We have observed AA-like symptoms in our IFN-γ adenylate-uridylate-rich element (ARE)-deleted (del) mice, which constitutively express a low level of IFN-γ under normal physiologic conditions. Because no T-cell autoimmunity was observed, we hypothesized that IFN-γ may be directly involved in the pathophysiology of AA. In these mice, we did not detect infiltration of T cells in bone …

Functional Lung Avoidance For Individualized Radiotherapy (Flair): Study Protocol For A Randomized, Double-Blind Clinical Trial., Douglas A Hoover, Dante Pi Capaldi, Khadija Sheikh, David A Palma, George B Rodrigues, A Rashid Dar, Edward Yu, Brian Dingle, Mark Landis, Walter Kocha, Michael Sanatani, Mark Vincent, Jawaid Younus, Sara Kuruvilla, Stewart Gaede, Grace Parraga, Brian P Yaremko

Medical Biophysics Publications

BACKGROUND: Although radiotherapy is a key component of curative-intent treatment for locally advanced, unresectable non-small cell lung cancer (NSCLC), it can be associated with substantial pulmonary toxicity in some patients. Current radiotherapy planning techniques aim to minimize the radiation dose to the lungs, without accounting for regional variations in lung function. Many patients, particularly smokers, can have substantial regional differences in pulmonary ventilation patterns, and it has been hypothesized that preferential avoidance of functional lung during radiotherapy may reduce toxicity. Although several investigators have shown that functional lung can be identified using advanced imaging techniques and/or demonstrated the feasibility and …

The Relationship Of Plantar Sensation With Standing Balance And Gait Post-Stroke, Stephen Parsons

Electronic Thesis and Dissertation Repository

Gait and balance dysfunction after stroke limit independence and quality of life. Numerous contributing factors have been investigated but the role of sensation deficits has received little attention. This thesis investigated the relationship between plantar cutaneous sensation and 1) standing balance, 2) gait, and 3) use of vision to compensate for sensory loss with a secondary analysis of data from individuals with subacute stroke. Associations between standing balance, gait and sensation were investigated with Spearman correlations. Individuals classified as impaired or intact sensation were compared on gait and standing balance measures. This thesis found plantar sensation is related to standing …

A Critical Analysis Of Infant Mortality In Kalamazoo County, Audrey Jensen

Honors Theses

The following is a review of the state of infant and fetal health in Kalamazoo County in the 21st century. Since infant health is a marker for the effectiveness of health care, this review will analyze the leading causes of infant mortality in Kalamazoo County. Statistical indicators show that Kalamazoo County falls below both state and national IMR averages. The leading causes of infant mortality in Kalamazoo are considered preventable infant deaths. Therefore, this review will make recommendations for the reduction of IMR through the improvement of preventative prenatal healthcare practices.

The Effect Of Chronic Sleep Deprivation On Tumor Necrosis Factor Alpha And Bone Health In Peri-Menopausal Rats, Megan Robertson, Derek Booth, Erin Wainwright, Cody Arbuckle, Frank Frisch

Student Scholar Symposium Abstracts and Posters

Post-menopausal osteoporosis is a common syndrome in the United States. The cessation of estrogen signaling coupled with the production of pro-inflammatory cytokines from sleep deprivation leads to an even greater risk of post-menopausal osteoporosis by creating an imbalance between osteoblasts and osteoclasts. With estrogen no longer present to regulate the concentration of osteoclasts and pro-inflammatory cytokines increasing production of osteoclasts, bone is degraded at a faster rate than it is formed. One of the most common treatments for osteoporosis is Zolendronate (a nitrogenous bisphosphonate), which decreases the number of osteoclasts in bone. This preliminary study looked at the effects on …

Accommodating Hyperaroused Information Processing In Persons At Risk For Alcoholism, Kellianne Clark, Jaclyn Cutler

Student Scholar Symposium Abstracts and Posters

In the search for the factors related to the heightened alcoholism risk in adult children of alcoholics (ACOA), it has been reported that these persons possess a high incidence of attention deficit disorders (ADD) as determined by clinical assessment instruments. However, investigations of alcoholism risk and ADD indicate that, in contrast to the hypoarousal model of ADD, the ACOA’s attention problems represent hyperarousal of attention mechanisms resulting in reduced ability to select and encode relevant information. If true, then unlike persons with ADD, clinical and cognitive assessments of ACOAs would benefit if the ACOA was provided with more time to …

Effect Of Dual Tasking On Walking Over Even And Uneven Surfaces In Functionally Independent Community Older Adults, Olajide L. Kolawole

Seton Hall University Dissertations and Theses (ETDs)

While several studies have reported a decrement in performance by older adults while walking and concurrently performing a dual task on even surfaces, to date the effects of dual tasking while walking on uneven surfaces commonly found in the community has received less attention. Thus, we sought to test the hypothesis that an incremental decrement in gait parameters will be observed, when walking on an uneven versus an even surface and furthermore, that this decrement would be dependent upon the concurrent performance of a secondary cognitive and/or motor task in functionally independent-living-community older adults.

Dynamic Gait Index assessed the subject’s …
