Criminal Law And Common Sense: An Essay On The Perils And Promise Of Neuroscience, Stephen J. Morse

All Faculty Scholarship

This article is based on the author’s Barrock Lecture in Criminal Law presented at the Marquette University Law School. The central thesis is that the folk psychology that underpins criminal responsibility is correct and that our commonsense understanding of agency and responsibility and the legitimacy of criminal justice generally are not imperiled by contemporary discoveries in the various sciences, including neuroscience and genetics. These sciences will not revolutionize criminal law, at least not anytime soon, and at most they may make modest contributions to legal doctrine, practice, and policy. Until there are conceptual or scientific breakthroughs, this is my story …

Research Roundup From The Research Committee, Mary Insana Fisher, Shana Harrington

Mary Insana Fisher

With the expectations of accountability by consumers and third party payors for the efficacy of physical therapy practice, there has been a significant increase in the push to develop outcome measures in rehabilitation. One type of these measures, patient-reported outcome measures (PROs), are becoming increasingly more common in clinical practice. The American Physical Therapy Association’s Guide to Physical Therapist Practice 3rd edition includes outcomes assessment as an integral part of the Patient and Client Management model, and delineates that appropriate tests and measures depend upon established psychometric properties of the measurement.1 The Section on Research formed the Evidence Database to …

Oncology Section Edge Task Force On Breast Cancer Outcomes: A Systematic Review Of Outcome Measures For Functional Mobility, Mary Insana Fisher, Jeannette Lee, Claire Davies, Hannah Geyer, Genevieve Colon, Lucinda Pfalzer

Mary Insana Fisher

Background: Breast cancer treatments in women with breast cancer often result in physical impairments that lead to activity limitations and participation restrictions. These limitations and restrictions manifest in impaired functional mobility skills that may impact survivorship. Thus, evaluation of functional mobility is an important part of survivorship care. Purpose: To identify functional mobility outcome measures that possess strong psychometric properties and are clinically useful for examination of women treated for breast cancer. Methods: Multiple electronic databases were searched for articles published after 1995. Studies were included if they reported psychometric properties, used clinically feasible methods, were performed on adults, and …

Knee Range Of Motion: Reliability And Agreement Of 3 Measurement Methods, Paul G. Peters, Michael A. Herbenick, Philip A. Anloague, Ronald J. Markert, L. Joseph Rubino

Philip A. Anloague

We conducted a study to compare 3 methods of measuring knee range of motion: visual estimation by physicians, hand goniometry by physical therapists, and radiographic goniometry. We hypothesized that reliability would be high within and across all techniques. We found intrarater and interrater reliability to be satisfactory for visual estimation, hand goniometry, and radiographic goniometry. Interrater reliability across methods did not agree satisfactorily. Between-methods differences in estimating knee range of motion may result from variations in technique among physicians and physical therapists.

The Association Between Critical Thinking And Scholastic Aptitude On First-Time Pass Rate Of The National Physical Therapy Examination, Daniel W. Suckow, C. Jayne Brahler, Betsy Donahoe-Fillmore, Mary Insana Fisher, Philip A. Anloague

Philip A. Anloague

Objectives: 1) To investigate the relationships among critical thinking (CT) abilities, overall academic performance in the Doctorate of Physical Therapy (DPT) program as measured by cumulative grade point average (GPA), and National Physical Therapy Examination (NPTE) licensure scores, and 2) To determine if NPTE scores were significantly different between groups of students who were classified as having low, moderate or high CT abilities. Background: It is well-established that physical therapy practice requires good clinical reasoning skills. Passage of the NPTE is required for licensure. Research to date has been mixed as to whether CT abilities or GPA can predict success …

Philip A. Anloague

In the United States, chronic unreduced elbow dislocations are rare injuries. We report the successful short-term outcome of a chronic elbow dislocation treated with open reduction and lateral ulnar collateral ligament reconstruction using a split semitendinosus allograft in a figure-of-8 technique without use of hinged external fixation. The authors have obtained the patient’s written informed consent for print and electronic publication of the case report.

Development Of Oral Vaccines Against Lyme Disease, Rita Raquel Dos Anjos De Carvalho E Melo

Theses and Dissertations (ETD)

Lyme Disease, caused by the spirochete Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. If left untreated, it can lead to permanent damage to the nervous and musculoskeletal systems. In some cases, patients that receive the recommended antibiotic therapy develop a debilitating health condition associated with substantial health care costs. Despite current preventive measures, the incidence and the geographic distribution of Lyme Disease continues to increase. Recent estimates from CDC suggest that the true number of cases of Lyme Disease in the US is approximately 300,000 per year. Yet, there is currently no vaccine …

A Synthetic Porcine Reproductive And Respiratory Syndrome Virus Strain Confers Unprecedented Levels Of Heterologous Protection, Hiep Vu, Fangrui Ma, William W. Laegreid, Asit K. Pattnaik, David Steffen, Alan R. Doster, Fernando Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

Current vaccines do not provide sufficient levels of protection against divergent porcine reproductive and respiratory syndrome virus (PRRSV) strains circulating in the field, mainly due to the substantial variation of the viral genome. We describe here a novel approach to generate a PRRSV vaccine candidate that could confer unprecedented levels of heterologous protection against divergent PRRSV isolates. By using a set of 59 nonredundant, full-genome sequences of type 2 PRRSVs, a consensus genome (designated PRRSV-CON) was generated by aligning these 59 PRRSV full-genome sequences, followed by selecting the most common nucleotide found at each position of the alignment. Next, the …

Greater Magnocellular Saccadic Suppression In High Versus Low Autistic Tendency Suggests A Causal Path To Local Perceptual Style., David P Crewther, Daniel Crewther, Stephanie Bevan, Melvyn A Goodale, Sheila G Crewther

Brain and Mind Institute Researchers' Publications

Saccadic suppression-the reduction of visual sensitivity during rapid eye movements-has previously been proposed to reflect a specific suppression of the magnocellular visual system, with the initial neural site of that suppression at or prior to afferent visual information reaching striate cortex. Dysfunction in the magnocellular visual pathway has also been associated with perceptual and physiological anomalies in individuals with autism spectrum disorder or high autistic tendency, leading us to question whether saccadic suppression is altered in the broader autism phenotype. Here we show that individuals with high autistic tendency show greater saccadic suppression of low versus high spatial frequency gratings …

Role Of Stat3 In Human Nk Cell Functions, Prasad V. Phatarpekar

Dissertations & Theses (Open Access)

Natural Killer (NK) cells are cytotoxic lymphocytes, which play a critical role in the immune response against malignant cells and microbial infections. NK cells are equipped with activating receptors, which upon detecting ligands expressed on stressed cells induce cytolytic activity of NK cells. Stimulation of NK cell proliferation and priming of NK cytolytic capability are accomplished by cytokines, which mediate their signals mainly through JAK-STAT signaling pathway. Previously, we found that K562 cells genetically modified to express membrane bound IL-21 (mbIL-21), which predominantly activates STAT3, induce robust expansion and activation of human NK cells. Further investigations revealed role of STAT3 …

Functional Analysis Of Genomic Variation And Impact On Molecular And Higher Order Phenotypes, Ashutosh Kumar Pandey

Theses and Dissertations (ETD)

Reverse genetics methods, particularly the production of gene knockouts and knockins, have revolutionized the understanding of gene function. High throughput sequencing now makes it practical to exploit reverse genetics to simultaneously study functions of thousands of normal sequence variants and spontaneous mutations that segregate in intercross and backcross progeny generated by mating completely sequenced parental lines. To evaluate this new reverse genetic method we resequenced the genome of one of the oldest inbred strains of mice—DBA/2J—the father of the large family of BXD recombinant inbred strains. We analyzed ~100X wholegenome sequence data for the DBA/2J strain, relative to C57BL/6J, the …

Genetic Control Of Survival And Weight Loss During Pneumonic Burkholderia Pseudomallei (Bp) Infection, Felicia D. Emery

Theses and Dissertations (ETD)

Burkholderia pseudomallei (Bp) is a saprophytic, gram-negative aerobe and the causative agent of the disease melioidosis. Melioidosis is an infectious disease that occurs in humans and animals and is prevalent in Southeast Asia, northern Australia and other tropical areas. Transmission occurs through direct contact with the organism via ingestion, inhalation, or through open wounds and skin abrasions. Clinical presentation is extremely variable and can range from acute septicemia with bacterial dissemination to distant sites, to an isolated pulmonary infection. Treatment of melioidosis can be problematic because it is often difficult to diagnose and Bp is resistant to a diverse group …

The Neurochemistry Of Group Singing: Bonding And Oxytocin, Jason Keeler

Masters Theses

The purpose of this study was to examine the neurochemical correlates of group vocal improvisation and to determine the feasibility of the research methods. One group of four participants sang together in two conditions: pre-composed and improvised. Concentrations of plasma oxytocin and adrenocorticotropic hormone (ACTH) were measured before and after each singing condition to assess levels of hormones associated with social affiliation, engagement and arousal. Successful implementation of the methodology, including recruitment, data collection, and sample analysis, served as the primary outcome of this study. ACTH concentrations decreased in both conditions, and significantly so in the pre-composed singing condition. Mean …

Mechanisms By Which Dietary Ellagic Acid Attenuates Obesity And Obesity-Mediated Metabolic Complications, Inhae Kang

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Ellagic acid (EA) is a polyphenol found in various fruits and plants, such as berries, pomegranates, muscadine grapes, nuts and bark of oak tree. EA has been known to exhibit anti-inflammatory and anti-proliferative effects in various types of cancer. However, little is known about the effects of EA on obesity. Herein, 1) the lipid-lowering role of EA was identified in primary human adipose stem cells (hASCs) and human hepatoma Huh7 cells; 2) the molecular mechanisms by which EA attenuates adipogenesis by epigenetic modification were identified; 3) the effects of EA on high fat and high sucrose-mediated obesity was …

Viability Of Developmental Stages Of Schistosoma Mansoni Quantified With Xcelligence Worm Real-Time Motility Assay (Xworm)., Gabriel Rinaldi, Alex Loukas, Paul J. Brindley, Jeff T. Irelan, Michael J. Smout

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Infection with helminth parasites causes morbidity and mortality in billions of people and livestock worldwide. Where anthelmintic drugs are available, drug resistance is a major problem in livestock parasites, and a looming threat to public health. Monitoring the efficacy of these medicines and screening for new drugs has been hindered by the lack of objective, high-throughput approaches. Several cell monitoring technologies have been adapted for parasitic worms, including video-, fluorescence-, metabolism enzyme- and impedance-based tools that minimize the screening bottleneck. Using the xCELLigence impedance-based system we previously developed a motility-viability assay that is applicable for a range of helminth parasites. …

Functional Analysis Of The Unique Cytochrome P450 Of The Liver Fluke Opisthorchis Felineus., Mariya Y. Pakharukova, Valentin A. Vavilin, Banchob Sripa, Thewarach Laha, Paul J. Brindley, Viatcheslav A. Mordvinov

Microbiology, Immunology, and Tropical Medicine Faculty Publications

The basic metabolic cytochrome P450 (CYP) system is essential for biotransformation of sterols and xenobiotics including drugs, for synthesis and degradation of signaling molecules in all living organisms. Most eukaryotes including free-living flatworms have numerous paralogues of the CYP gene encoding heme monooxygenases with specific substrate range. Notably, by contrast, the parasitic flatworms have only one CYP gene. The role of this enzyme in the physiology and biochemistry of helminths is not known. The flukes and tapeworms are the etiologic agents of major neglected tropical diseases of humanity. Three helminth infections (Opisthorchis viverrini, Clonorchis sinensis and Schistosoma haematobium) are considered …

Masters Theses

Effects of varus knee alignment on the internal knee abduction moment (KAM) in walking has been widely studied. KAM has been shown to be closely associated with the development of medial knee osteoarthritis (OA). Despite the importance of the knee alignment, no studies have explored its effects on knee frontal plane biomechanics during stationary cycling. The purpose of this study was to examine the effects of varus knee alignment and using a toe-cage on the knee frontal plane biomechanics during stationary cycling. Eleven participants in each of the varus and neutral groups participated in the study. The participants performed in …

Immunomodulation Of Myeloid-Derived Suppressor Cells By Particulate B-Glucan In Cancer., Sabrin Husein Albeituni

Electronic Theses and Dissertations

Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature myeloid cells that promote tumor progression. In this study, we investigated the effect of dectin-1 stimulation by yeast-derived particulate β-glucan in MDSC function and differentiation in cancer. In vivo treatment of mice bearing lewis lung carcinoma and mammary cell carcinoma with particulate β-glucan decreased tumor weight and splenomegaly, and reduced the accumulation of polymorphonuclear-MDSC (PMN-MDSC) but not monocytic-MDSC (M-MDSC) in the spleen and tumor. In addition, particulate β-glucan differentially modulated the function of different MDSC subsets; it enhanced PMN-MDSC respiratory burst and apoptosis, and induced the differentiation of M-MDSC into …

Methylseleninic Acid Promotes Antitumour Effects Via Nuclear Foxo3a Translocation Through Akt Inhibition, Míriam Tarrado-Castellarnau, Roldán Cortés, Miriam Zanuy, Josep Tarragó-Celada, Ibrahim H. Polat, Richard Hill, Teresa W-M Fan, Wolfgang Link, Marta Cascante

Toxicology and Cancer Biology Faculty Publications

Selenium supplement has been shown in clinical trials to reduce the risk of different cancers including lung carcinoma. Previous studies reported that the antiproliferative and pro-apoptotic activities of methylseleninic acid (MSA) in cancer cells could be mediated by inhibition of the PI3K pathway. A better understanding of the downstream cellular targets of MSA will provide information on its mechanism of action and will help to optimize its use in combination therapies with PI3K inhibitors. For this study, the effects of MSA on viability, cell cycle, metabolism, apoptosis, protein and mRNA expression, and reactive oxygen species production were analysed in A549 …

The Neurobiology Of Circadian Rhythms, Patricia J. Sollars, Gary E. Pickard

School of Veterinary and Biomedical Sciences: Faculty Publications

Daily rhythms in nature, such as the opening and closing of flowers or our patterns of sleep and wakefulness and their association with the perpetual alteration of night and day, were recognized in antiquity although their origins were not questioned until the eighteenth century. The French Astronomer Jean-Jacques d’Ortous de Mairan conducted an investigation into whether the leaves of the Mimosa plant opened in response to light.¹ While de Mairan’s experiments were the first to question the origin of such daily rhythms, Augustin Pyramus de Candolle is credited with the first suggestion that they arose through an internal timekeeping …

Interaction Of Alu Polymorphisms And Novel Measures Of Discrimination In Association With Blood Pressure In African Americans Living In Tallahassee, Alexis C. Boulter, Jackyn Quinlan, Aida T. Miró-Herrans, Laurel N. Pearson, Nubiana L. Todd, Clarence C. Gravlee, Connie J. Mulligan

Human Biology Open Access Pre-Prints

African Americans are 40% more likely to be afflicted with hypertension in comparison to non-Hispanic, white Americans, resulting in a 30% higher instance of mortality due to cardiovascular disease. There is debate about the relative contributions of genetic and sociocultural risk factors to the racial disparity in hypertension.

We assayed three Alu insertion polymorphisms located in the angiotensin-1-converting enzyme (ACE), tissue plasminogen activator (PLAT), and with no-lysine kinase 1 (WNK1) genes. We also estimated West African genetic ancestry and developed novel measures of perceived discrimination to create a biocultural model of blood pressure among …

Cardiovascular Regulation And Effects Of Respiratory Motor Training In Patients With Chronic Spinal Cord Injury., Bonnie Legg Ditterline

Electronic Theses and Dissertations

This dissertation attempts to discover the mechanisms between cardiovascular and respiratory motor control post spinal cord injury (SCI): in normal, non-injured (NI) persons, cardiovascular regulation is dependent upon respiration, but there is nothing that suggests the mechanism for this relationship post-SCI. Thus we hoped to evaluate various aspects of cardiovascular regulation to further illustrate how this relationship is changed or unchanged by SCI. Chapter I describes the anatomy and physiology of the spine, respiratory system, and cardiovascular system in a NI person, and then describes how the function of these systems is changed by SCI. In addition, we describe therapies …

Investigation Of Quatitative Image Features From Pretreatment Ct And Fdg-Pet Scans In Stage Iii Nsclc Patients Undergoing Defintive Radiation Therapy, David Fried

Dissertations & Theses (Open Access)

The purpose of this work was to determine if quantitative image features (QIFs) extracted from computed tomography (CT) and flourodeoxyglucose (FDG) positron emission tomography (PET) could provide prognostic information to improve outcome models. Our goal for this work was to determine if it may one day be feasible to incorporate QIFs into personalized cancer care. QIFs were used to quantitatively characterize patient disease as seen on imaging. A leave-one-out cross-validation procedure was used to assess the prognostic ability of QIFs extracted from CT and PET in addition to conventional prognostic factors (CPFs). QIFs were found to improve model fit for …

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig

Dissertations & Theses (Open Access)

The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …

Introduction: Childhood obesity is a problem that leads to many serious health effects including early maturation, decreased quality of life and increased risk for cardiovascular disease. In 2012, over one third of children were considered obese (Childhood Obesity Facts 2015). Efforts have been made to reduce this number but they have not been fully successful (Nutrition Standards for School Meals 2015, Prevalence of Childhood obesity in the United States 2011-2012 2015). What other factors are causing kids to choose foods that lead to weight gain.

Literature Review: In research regarding psychological motivations of overeating, there has been a correlation …

Endoplasmic Reticulum Stress And Ethanol Neurotoxicity, Fanmuyi Yang, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Ethanol abuse affects virtually all organ systems and the central nervous system (CNS) is particularly vulnerable to excessive ethanol exposure. Ethanol exposure causes profound damages to both the adult and developing brain. Prenatal ethanol exposure induces fetal alcohol spectrum disorders (FASD) which is associated with mental retardation and other behavioral deficits. A number of potential mechanisms have been proposed for ethanol-induced brain damage; these include the promotion of neuroinflammation, interference with signaling by neurotrophic factors, induction of oxidative stress, modulation of retinoid acid signaling, and thiamine deficiency. The endoplasmic reticulum (ER) regulates posttranslational protein processing and transport. The accumulation of …

Systemic Insulin Sensitivity And Skeletal Muscle Akt Signaling In Rats Artificially Selected For Low And High Aerobic Capacity, Kyle Levi Fulghum

MSU Graduate Theses

The mechanism(s) linking physical inactivity, obesity, and type-II diabetes are unclear. I hypothesized low intrinsic aerobic capacity is associated with reduced systemic insulin sensitivity via skeletal muscle insulin signaling. After 34 generations of selective breeding, high aerobic capacity (HCR) rats exhibited an 8-fold increase in running distance vs low aerobic capacity (LCR) rats (n=14 per group). LCR rats had higher rates of weight gain vs HCR (p<0.05) though food consumption was constant (p=0.86) over a 12-week study. Rats were divided into 4 groups: 1) LCR-Sham Surgery, 2) LCR-Catheterization, 3) HCR-Sham Surgery or 4) HCR-Catheterization (n=7 per group). Euglycemic-hyperinsulinemic clamps on catheterized rats tested insulin sensitivity while sham LCR and HCR were used for basal tissue analysis. Plasma insulin levels did not differ during the clamps, but LCR required lower glucose infusion rates than HCR (p<0.05). Upon insulin stimulation, both absolute and normalized phospho-Akt(Ser473) of soleus muscle were significantly increased in HCR above basal group (p<0.05), but not in LCR. No difference was observed between insulin-stimulated phospho-Akt(Ser473) of HCR and LCR groups . These data support that LCR is linked to a reduction in insulin sensitivity in vivo without impairments of insulin-stimulated skeletal muscle phospho-Akt(Ser473) vs HCR rats.

Non-Specific Blocking Of Mir-17-5p Guide Strand In Triple Negative Breast Cancer Cells By Amplifying Passenger Strand Activity., Yuan-Yuan Jin, Jade Andrade, Eric Wickstrom

Department of Biochemistry and Molecular Biology Faculty Papers

Conventional wisdom holds that only one of the two strands in a micro ribonucleic acid (miRNA) precursor duplex is selected as the active miRNA guide strand. The complementary miRNA passenger strand, however, is thought to be inactive. High levels of the oncogenic miRNA (oncomiR) guide strand called miR-17-5p is overexpressed in triple negative breast cancer (TNBC) and can inhibit ribosomal translation of tumor suppressor gene mRNAs, such as programmed cell death 4 (PDCD4) or phosphatase and tensin homolog (PTEN). We hypothesized that knocking down the oncogenic microRNA (oncomiR) miR-17-5p might restore the expression levels of PDCD4 and PTEN tumor suppressor …

Development And Evaluation Of Amphotericin B Loaded Iron Oxide Nanoparticles For Targeted Drug Delivery To Systemic Fungal Infections, Pavan Balabathula

Theses and Dissertations (ETD)

A targeted nanotheronostic drug delivery system to diagnose and treat life threatening invasive fungal infections (IFIs) such as cryptococcal meningitis was designed, developed, characterized, and evaluated. To address the development processes, first, iron oxide nanoparticles (IONP) (34-40 nm) coated with bovine serum albumin (BSA), loaded and targeted with amphotericin B (AMB) (AMB-IONP) was formulated by applying a layer by layer approach. Several designs (A, B, C, D, & E) of AMB-IONP were developed and their physicochemical properties such as drug loading with HPLC method, particle size, poly dispersity index (PDI), and ζ-potential using dynamic light scattering (DLS) technique, morphology with …
