Synthesis Of Novel Library Of Cyanopyrrolidinyl Beta-Amino Alcohols And Matrine Alkaloids, Xiaotian Chen

Theses and Dissertations

Cyanopyrrolidines and beta-Amino alcohols are molecular scaffolds that are highly found in commercially available drugs. We developed a multi-step synthetic method to form a novel library of compounds as inhibitors that share both scaffolds toward potent and selective diabetes therapeutics. Despite the ease for the synthesis of Cyanopyrrolidines, the difficulty of forming high selective beta-Amino alcohols is challenging. We successfully find the best condition for the preference of highly selective mono-alkylation and double-alkylation products and produce them with high yield.

Matrine is an alkaloid found in plants from the genus Sophora and can produce some pharmacological effects such as anti-cancer …

Expression Of Cyclin D1 In Clear Cell Sarcoma Of Kidney. Is It Useful In Differentiating It From Its Histological Mimics?, Nasir Uddin Ahmed, Khurram Minhas, Jamshid Abdul Ghafar, Arsalan Ahmed, Zubair Ahmad

Department of Pathology and Laboratory Medicine

Background: Clear cell sarcoma of the kidney (CCSK) is a rare malignant pediatric renal neoplasm with a heterogeneous histological appearance which often results in misdiagnosis. There are no specific immunohistochemical markers which can help in differentiating CCSK from other pediatric renal neoplasms. Recently Cyclin D1 has been investigated as a possible marker in this regard. In this study, we aim to determine the usefulness of Cyclin D1 in differentiating between CCSK and other pediatric renal neoplasms and to compare our results with those of recently published studies.
Methods: A total of 48 cases of CCSK, Wilms tumor (WT), renal rhabdoid …

Welfare Challenges Influence The Complexity Of Movement: Fractal Analysis Of Behaviour In Zebrafish, Anthony G. Deakin, Joseph W. Spencer, Andrew R. Cossins, Iain S. Young, Lynne U. Sneddon

Experimental Research and Animal Welfare Collection

The ability to assess welfare is an important refinement that will ensure the good condition of animals used in experimentation. The present study investigated the impact of invasive procedures on the patterns of movement of zebrafish (Danio rerio). Recordings were made before and after fin clipping, PIT tagging and a standard pain test and these were compared with control and sham handled zebrafish. The fractal dimension (FD) from the 3D trajectories was calculated to determine the effect of these treatments on the complexity of movement patterns. While the FD of zebrafish trajectories did not differ over time in either the …

Clinical and Translational Science Institute

Within lifestyle behavior research, the sex of populations causes differences in behaviors and outcomes of studies. This cross-sectional study investigated lifestyle behavior patterns in college students, examining sex differences in four areas: Nutrition, physical activity, sleep, and stress. Data from over 1100 college freshmen across 8 United States universities were used for this cross-sectional analysis. Self-reported data assessed fruit and vegetable intake, fat percent intake, physical activity, perceived stress, and sleep quality. Statistical analysis included Pearson chi-squared and Mann–Whitney’s U tests for scores by sex. Likewise, healthy cut-offs were used to determine frequency of participants within range of the five …

A Pilot Study Of The Effects Of Mycoplasma Ovipneumoniae Exposure On Domestic Lamb Growth And Performance, Thomas E. Besser, Jessica Levy, Melissa Ackerman, Danielle Nelson, Kezia R. Manlove, Kathleen A. Potter, Jan Busboom, Margaret Benson

Wildland Resources Faculty Publications

Mycoplasma ovipneumoniae is a globally distributed pathogen that has been associated with pneumonia in both domestic and wild Caprinae. It is closely related to M. hyopneumoniae, a respiratory pathogen of swine that is associated with decreased growth rates of pigs as well as clinical respiratory disease. In order to assess the effects of M. ovipneumoniae on lamb performance, we generated a cohort of lambs free of M. ovipneumoniae by segregation of test negative ewes after lambing, then compared the growth and carcass quality traits of M. ovipneumoniae-free and -colonized lambs from weaning to harvest. Some signs of respiratory disease …

Adipose-Derived Autotaxin Regulates Inflammation And Steatosis Associated With Diet-Induced Obesity, J. Anthony Brandon, Maria Kraemer, Julia Vandra, Suchismita Halder, Margo F. Ubele, Andrew J. Morris, Susan S. Smyth

Gill Heart & Vascular Institute Faculty Publications

Autotaxin (ATX) is a secreted enzyme that generates the bioactive lipid lysophosphatidic acid (LPA). We generated mice with global inducible post-natal inactivation or adipose-specific loss of the Enpp2 gene encoding ATX. The animals are phenotypically unremarkable and exhibit differences in adipocyte size and adipose tissue expression of inflammatory genes after high fat feeding without gross differences in fat distribution or body mass. Surprisingly, both models of Enpp2- deficiency exhibited marked protection from high fat diet-induced hepatic steatosis. This phenotype was not associated with differences in dietary fat absorption but may be accounted for by differences in hepatic expression of …

Carboxylic Acids Accelerate Acidic Environment-Mediated Nanoceria Dissolution, Robert A. Yokel, Matthew L. Hancock, Eric A. Grulke, Jason M. Unrine, Alan K. Dozier, Uschi M. Graham

Pharmaceutical Sciences Faculty Publications

Ligands that accelerate nanoceria dissolution may greatly affect its fate and effects. This project assessed the carboxylic acid contribution to nanoceria dissolution in aqueous, acidic environments. Nanoceria has commercial and potential therapeutic and energy storage applications. It biotransforms in vivo. Citric acid stabilizes nanoceria during synthesis and in aqueous dispersions. In this study, citrate-stabilized nanoceria dispersions (∼4 nm average primary particle size) were loaded into dialysis cassettes whose membranes passed cerium salts but not nanoceria particles. The cassettes were immersed in iso-osmotic baths containing carboxylic acids at pH 4.5 and 37 °C, or other select agents. Cerium atom material …

Does Work-Induced Fatigue Accumulate Across Three Compressed 12 Hour Shifts In Hospital Nurses And Aides?, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

Fatigue-related impairments in the nursing workforce contribute to a multitude of health, safety, and economic consequences at the individual, organizational and societal levels. Long and compressed work schedules are commonly worked in the healthcare industry, but more research is needed to understand the cumulative effects of multiple work shifts on physiology-based performance outcomes in nurses. The purpose of this study was to compare the effects of a single nursing work shift versus three compressed (one every 24 hours) 12 hour shifts on performance-based fatigue in nurses and aides. Twenty-six fulltime hospital working nurses and aides (age = 36.1 ± 13.3 …

Numb Regulates The Endocytosis And Activity Of The Anaplastic Lymphoma Kinase In An Isoform-Specific Manner, Ran Wei, Xuguang Liu, Courtney Voss, Wentao Qin, Lina Dagnino, Lei Li, Marc Vigny, Shawn Shun Cheng Li

Paediatrics Publications

NUMB is an evolutionarily conserved protein that plays an important role in cell adhesion, migration, polarity, and cell fate determination. It has also been shown to play a role in the pathogenesis of certain cancers, although it remains controversial whether NUMB functions as an oncoprotein or tumor suppressor. Here, we show that NUMB binds to anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase aberrantly activated in several forms of cancer, and this interaction regulates the endocytosis and activity of ALK. Intriguingly, the function of the NUMB-ALK interaction is isoform-dependent. While both p66-NUMB and p72-NUMB isoforms are capable of mediating the …

Intrinsic Functional Boundaries Of Lateral Frontal Cortex In The Common Marmoset Monkey, David J. Schaeffer, Kyle M. Gilbert, Joseph S. Gati, Ravi S. Menon, Stefan Everling

Brain and Mind Institute Researchers' Publications

© 2019 the authors. The common marmoset (Callithrix jacchus) is a small New World primate species that has been recently targeted as a potentially powerful preclinical model of human prefrontal cortex dysfunction. Although the structural boundaries of frontal cortex were described in marmosets at the start of the 20th century (Brodmann, 1909) and refined more recently (Paxinos et al., 2012), the broad functional boundaries of marmoset frontal cortex have yet to be established. In this study, we sought to functionally derive boundaries of the marmoset lateral frontal cortex (LFC) using ultra-high field (9.4 T) resting-state functional magnetic resonance imaging (RS-fMRI). …

Human Consciousness Is Supported By Dynamic Complex Patterns Of Brain Signal Coordination, A. Demertzi, E. Tagliazucchi, S. Dehaene, G. Deco, P. Barttfeld, F. Raimondo, C. Martial, D. Fernández-Espejo, B. Rohaut, H. U. Voss, N. D. Schiff, A. M. Owen, S. Laureys, L. Naccache, J. D. Sitt

Brain and Mind Institute Researchers' Publications

Adopting the framework of brain dynamics as a cornerstone of human consciousness, we determined whether dynamic signal coordination provides specific and generalizable patterns pertaining to conscious and unconscious states after brain damage. A dynamic pattern of coordinated and anticoordinated functional magnetic resonance imaging signals characterized healthy individuals and minimally conscious patients. The brains of unresponsive patients showed primarily a pattern of low interareal phase coherence mainly mediated by structural connectivity, and had smaller chances to transition between patterns. The complex pattern was further corroborated in patients with covert cognition, who could perform neuroimaging mental imagery tasks, validating this pattern’s implication …

Visual Habituation In Deaf And Hearing Infants, Claire Monroy, Carissa Shafto, Irina Castellanos, Tonya Bergeson, Derek Houston

Scholarship and Professional Work - Communication

Early cognitive development relies on the sensory experiences that infants acquire as they explore their environment. Atypical experience in one sensory modality from birth may result in fundamental differences in general cognitive abilities. The primary aim of the current study was to compare visual habituation in infants with profound hearing loss, prior to receiving cochlear implants (CIs), and age-matched peers with typical hearing. Two complementary measures of cognitive function and attention maintenance were assessed: the length of time to habituate to a visual stimulus, and look-away rate during habituation. Findings revealed that deaf infants were slower to habituate to a …

Identification Of Pre-Symptomatic Gene Signatures That Predict Resilience To Cognitive Decline In The Genetically Diverse Ad-Bxd Model., Sarah M Neuner, Sarah E Heuer, Ji-Gang Zhang, Vivek M. Philip, Catherine Kaczorowski

Faculty Research 2019

Across the population, individuals exhibit a wide variation of susceptibility or resilience to developing Alzheimer's disease (AD). Identifying specific factors that promote resilience would provide insight into disease mechanisms and nominate potential targets for therapeutic intervention. Here, we use transcriptome profiling to identify gene networks present in the pre-symptomatic AD mouse brain relating to neuroinflammation, brain vasculature, extracellular matrix organization, and synaptic signaling that predict cognitive performance at an advanced age. We highlight putative drivers of these observed relationships, including
