The life threatening disease of sepsis is associated with high mortality. Septic patient survivability with currently available treatments has failed to improve. The purpose of this study was to evaluate whether lipopolysaccharide (LPS) induced sepsis mortality and associated hepatic dysfunction can be prevented by cerium oxide nanoparticles (CeO2NPs) treatment in male Sprague Dawley rats. Here we provide the information about the methods processing of raw data related to our study published in Biomaterials (Selvaraj et al., Biomaterials, 2015, In press) and Data in Brief (Selvaraj et al., Data in Brief, 2015, In Press). The data present here provides confirmation of ...


30-Day Oral Acetaminophen Tolerance In Adult Horses, Sarah E. Foreman 2018 Augustana College, Rock Island Illinois

30-Day Oral Acetaminophen Tolerance In Adult Horses, Sarah E. Foreman

Celebration of Learning

There are no controlled studies of acetaminophen toxicity in horses. The objective was to test the hypotheses that oral acetaminophen administered at a dosage 25% higher than that sometimes used in horses would result in measurable hepatic toxicity as seen in humans and other species. Six healthy adult horses were administered 25 mg/kg acetaminophen powder in corn syrup twice daily for 30 days. Three other horses served as negative controls receiving only corn syrup. Jugular venous blood samples were obtained on days 7 and 1 before treatment; on treatment days 1, 2, 5, 8, 12, 15, 19, 22, 26 ...

Imbalanced expression of somatic alleles in cancer can suggest functional and selective features, and can therefore indicate possible driving potential of the underlying genetic variants. To explore the correlation between allele frequency of somatic variants and total gene expression of their harboring gene, we used the unique data set of matched tumor and normal RNA and DNA sequencing data of 5523 distinct single nucleotide variants in 381 individuals across 10 cancer types obtained from The Cancer Genome Atlas (TCGA). We analyzed the allele frequency in the context of the variant and gene functional features and linked it with changes in ...

Disruption Of Neonatal Cardiomyocyte Physiology Following Exposure To Bisphenol-A., Manelle Ramadan, Meredith Sherman, Rafael Jaimes, Ashika Chaluvadi, Luther Swift, Nikki Gillum Posnack

Pharmacology and Physiology Faculty Publications

Bisphenol chemicals are commonly used in the manufacturing of polycarbonate plastics, polyvinyl chloride plastics, resins, and thermal printing applications. Humans are inadvertently exposed to bisphenols through contact with consumer products and/or medical devices. Recent reports have shown a link between bisphenol-a (BPA) exposure and adverse cardiovascular outcomes; although these studies have been limited to adult subjects and models. Since cardiac physiology differs significantly between the developing and adult heart, we aimed to assess the impact of BPA exposure on cardiac function, using a neonatal cardiomyocyte model. Neonatal rat ventricular myocytes were monitored to assess cell viability, spontaneous beating rate ...


Therapeutic Potential Of A Plant-Made Cholera Toxin B Subunit Variant For The Treatment Of Ulcerative Colitis., Joshua Mark Royal 2018 University of Louisville

Therapeutic Potential Of A Plant-Made Cholera Toxin B Subunit Variant For The Treatment Of Ulcerative Colitis., Joshua Mark Royal

Electronic Theses and Dissertations

Cholera toxin B subunit (CTB) is a mucosal immunomodulatory protein that induces robust mucosal and systemic antibody responses. This well-known biological activity has been exploited in cholera prevention (as a component of Dukoral® vaccine) and vaccine development for decades. On the other hand, several studies have investigated CTB’s immunotherapeutic potential in the treatment of inflammatory diseases such as Crohn’s disease and asthma. Furthermore, we recently found that a plant-made variant of CTB (CTBp) could induce colon epithelial wound healing in mouse colitis models. In this thesis, it is revealed that the wound healing effects are unique to the ...


Post-Traumatic Stress Disorder: Review Of Dsm Criteria And Functional Neuroanatomy, Cornelius W. Thomas 2018 Huntington VA Medical Center

Post-Traumatic Stress Disorder: Review Of Dsm Criteria And Functional Neuroanatomy, Cornelius W. Thomas

Marshall Journal of Medicine

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for post-traumatic stress disorder (PTSD) consist of over twenty possible symptoms that can be divided into six broad categories. These categories correlate with specific brain networks that regulate emotions, behaviors, and autonomic function. Normal functioning of these networks depends on two key regions; the prefrontal cortex and the amygdala. The prefrontal cortex provides top-down executive control over amygdala, whereas the amygdala is critical for threat detection and activation of the ‘fight or flight’ response. Events that trigger extreme and/or prolonged fear can cause persisting dysregulation within the prefrontal-amygdala circuit ...

Chronic antigenic stimulation leads to T cell exhaustion, which drastically dampens T cell effector functions. Upon exhaustion, T cells progressively lose their proliferative capacity, cytokine production, and cytotoxic effector functions against tumors. T cell exhaustion involves programmed cell death-1 (PD-1), which is an inhibitory co-stimulation receptor. Limited scope of studies has been done regarding impact of PD-1 expression on the effector functions of γδ T cells. In this study, we investigated expression of PD-1 and its impact on effector functions of human γδ T cells. When γδ T cells were stimulated with phosphoantigens (HMBPP and POM2-C-HMBP) and analyzed ...

Comparing The Side Effects Of Prescription Opioids And Medicinal Marijuana In The Treatment Of Chronic Pain, Callie Glenn, Ryan Bopp

Carroll College Student Undergraduate Research Festival

Opioids are medications that interact with receptors in the central nervous system to provide pain relief, and have been a standard foundation for treatment of chronic pain since their discovery. But advancements in medical technology have led to the discovery of several alternatives to narcotics, one being medical marijuana. Cannabis has become increasingly pertinent in the medical field due to the medicinal and recreational legalization of the substance in several states. The purpose of this Evidence Based Practice Brief is to determine how the side effects of medical marijuana compared to those of opioid treatment affect quality of life for ...

Optimizing Vaccine Immunotherapy For Prostate Cancer, G. Hattier, E. K. Bongiorno, C. Portocarrero, Trevor R. Baybutt, Adam E. Snook, U. Rodeck

Sigma Xi

Introduction: Treatment options for metastatic prostate cancer are limited and cures are rare. In other cancers immunotherapy has shown remarkable efficacy in certain patient subsets particularly when combined with other treatment modalities. Our previous work showed that combining radiation and vaccine therapy slows the growth of syngeneic prostate cancer in mice more effectively than single modality treatment arms. Here we tested the hypothesis that addition of immune checkpoint inhibitors targeting the PD1/PD-L1 axis further improves efficacy of the dual radiation/vaccine treatment.

Methods: Mice were injected with tumor cells expressing human prostate specific antigen (TPSA-23). The mice were divided ...

Effect Of Study Design On Sample Size In Studies Intended To Evaluate Bioequivalence Of Inhaled Short-Acting Β-Agonist Formulations, Yaohui Zeng, Sachinkumar Singh, Kai Wang, Richard C. Ahrens

Stead Family Department of Pediatrics Publications

Pharmacodynamic studies that use methacholine challenge to assess bioequivalence of generic and innovator albuterol formulations are generally designed per published Food and Drug Administration guidance, with 3 reference doses and 1 test dose (3-by-1 design). These studies are challenging and expensive to conduct, typically requiring large sample sizes. We proposed 14 modified study designs as alternatives to the Food and Drug Administration-recommended 3-by-1 design, hypothesizing that adding reference and/or test doses would reduce sample size and cost. We used Monte Carlo simulation to estimate sample size. Simulation inputs were selected based on published studies and our own experience with ...


Ajulemic Acid: Potential Treatment For Chronic Inflammation, Sumner Burstein 2018 University of Massachusetts Medical School

Ajulemic Acid: Potential Treatment For Chronic Inflammation, Sumner Burstein

Open Access Articles

Ajulemic acid (AJA, CT-3, IP-751, JBT-101, anabasum) is a first-in-class, synthetic, orally active, cannabinoid-derived drug that preferentially binds to the CB2 receptor and is nonpsychoactive. In preclinical studies, and in Phase 1 and 2 clinical trials, AJA showed a favorable safety, tolerability, and pharmacokinetic profile. It also demonstrated significant efficacy in preclinical models of inflammation and fibrosis. It suppresses tissue scarring and stimulates endogenous eicosanoids that resolve chronic inflammation and fibrosis without causing immunosuppression. AJA is currently being developed for use in 4 separate but related indications including systemic sclerosis (SSc), cystic fibrosis, dermatomyositis (DM), and systemic lupus erythematosus. Phase ...

BACKGROUND

Solid organ transplant recipients commonly require anticoagulation. Apixaban (APX) is principally metabolized by CYP3A4, undergoes direct intestinal excretion, and is a substrate to P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP) transporters. We examined the potential drug interaction between cyclosporine (CsA) and tacrolimus (Tac) [combined inhibitors of CYP3A4, P-gp and, BCRP] with APX.

Obesity is an ongoing global health concern and has only recently been recognized as a chronic disease of energy homeostasis and fuel partitioning. Obesity afflicts 17% of US children and adolescents. Severe obesity (³120% of the 95th percentile of BMI-for-age, or a BMI of ³35 kg/m2) is the fastest growing subgroup and now approaches 6% of all US youth. Health consequences (e.g., type 2 diabetes, coronary heart disease) are related in a dose-dependent manner to severity of obesity. Since therapeutic interventions are less effective in severe obesity, prevention is a high priority.

Biology Of Platelet Purinergic Receptors And Implications For Platelet Heterogeneity, Milka Koupenova-Zamor, Katya Ravid 2018 University of Massachusetts Medical School

Biology Of Platelet Purinergic Receptors And Implications For Platelet Heterogeneity, Milka Koupenova-Zamor, Katya Ravid

Open Access Articles

Platelets are small anucleated cells present only in mammals. Platelets mediate intravascular hemostatic balance, prevent interstitial bleeding, and have a major role in thrombosis. Activation of platelet purinergic receptors is instrumental in initiation of hemostasis and formation of the hemostatic plug, although this activation process becomes problematic in pathological settings of thrombosis. This review briefly outlines the roles and function of currently known platelet purinergic receptors (P1 and P2) in the setting of hemostasis and thrombosis. Additionally, we discuss recent novel studies on purinergic receptor distribution according to heterogeneous platelet size, and the possible implication of this distribution on hemostatic ...

The tumor suppressor protein retinoblastoma (RB) is mechanistically linked to suppression of transcription factor E2F1-mediated cell cycle regulation. For multiple tumor types, loss of RB function is associated with poor clinical outcome. RB action is abrogated either by direct depletion or through inactivation of RB function; however, the basis for this selectivity is unknown. Here, analysis of tumor samples and cell-free DNA from patients with advanced prostate cancer showed that direct RB loss was the preferred pathway of disruption in human disease. While RB loss was associated with lethal disease, RB-deficient tumors had no proliferative advantage and exhibited downstream effects ...

In vivo autofluorescence hyperspectral imaging of moving objects can be challenging due to motion artifacts and to the limited amount of acquired photons. To address both limitations, we selectively reduced the number of spectral bands while maintaining accurate target identification. Several downsampling approaches were applied to data obtained from the atrial tissue of adult pigs with sites of radiofrequency ablation lesions. Standard image qualifiers such as the mean square error, the peak signal-to-noise ratio, the structural similarity index map, and an accuracy index of lesion component images were used to quantify the effects of spectral binning, an increased spectral distance ...

Fluorescence optical imaging techniques have revolutionized the field of cardiac electrophysiology and advanced our understanding of complex electrical activities such as arrhythmias. However, traditional monocular optical mapping systems, despite having high spatial resolution, are restricted to a two-dimensional (2D) field of view. Consequently, tracking complex three-dimensional (3D) electrical waves such as during ventricular fibrillation is challenging as the waves rapidly move in and out of the field of view. This problem has been solved by panoramic imaging which uses multiple cameras to measure the electrical activity from the entire epicardial surface. However, the diverse engineering skill set and substantial resource ...


Role Of Sex Chromosomes In Sexual Dimorphism Of Angii-Induced Abdominal Aortic Aneurysms, Yasir Alsiraj 2018 University of Kentucky

Role Of Sex Chromosomes In Sexual Dimorphism Of Angii-Induced Abdominal Aortic Aneurysms, Yasir Alsiraj

Theses and Dissertations--Pharmacology and Nutritional Sciences

Abdominal aortic aneurysms (AAAs), a permanent dilation in the abdominal region of the aorta, is a highly sexually dimorphic disease. AAAs prevalence is ranging from 4-10 fold higher in males than females. Defining the mechanistic basis for reduced (in females) or increased (in males) AAA formation and progression may uncover potential therapeutic targets. The majority of studies examining sexual dimorphism focus on the role of sex hormones. However, genes residing on sex chromosomes, in addition to sex hormones, may contribute to sexual dimorphism of AAAs. For example, the X chromosome contains about 5% of the whole genome, but the role ...
