Suppression Of F1 Male-Specific Lethality In Caenorhabditis Hybrids By Cbr-Him-8, Vaishnavi Ragavapuram, Emily Elaine King, Scott Everet Baird

Biological Sciences Faculty Publications

Haldane's Rule and Darwin's Corollary to Haldane's Rule are the observations that heterogametic F1 hybrids frequently are less fit than their homogametic siblings and that asymmetric results often are obtained from reciprocal hybrid crosses. In Caenorhabditis, Haldane's Rule and Darwin's Corollary have been observed in several hybrid crosses, including crosses of Caenorhabditis briggsae and Caenorhabditis nigoni. Fertile F1 females are obtained from reciprocal crosses. However, F1 males obtained from C. nigoni mothers are sterile and F1 males obtained from C. briggsae die during embryogenesis. We have identified cbr-him-8 as a recessive maternal-effect suppressor of F1 hybrid male-specific lethality …

Sidestream Smoke Exposure Increases The Susceptibility Of Airway Epithelia To Adenoviral Infection, Priyanka Sharma, Abimbola O. Kolawole, Susan B. Core, Adriana E. Kajon, Katherine J.D.A. Excoffon

Biological Sciences Faculty Publications

Background: Although significant epidemiological evidence indicates that cigarette smoke exposure increases the incidence and severity of viral infection, the molecular mechanisms behind the increased susceptibility of the respiratory tract to viral pathogens are unclear. Adenoviruses are non-enveloped DNA viruses and important causative agents of acute respiratory disease. The Coxsackievirus and adenovirus receptor (CAR) is the primary receptor for many adenoviruses. We hypothesized that cigarette smoke exposure increases epithelial susceptibility to adenovirus infection by increasing the abundance of apical CAR. Methodology and Findings: Cultured human airway epithelial cells (CaLu-3) were used as a model to investigate the effect of sidestream cigarette …

A Randomized 2x2 Factorial Clinical Trial Of Renal Transplantation: Steroid-Free Maintenance Immunosuppression With Calcineurin Inhibitor Withdrawal After Six Months Associates With Improved Renal Function And Reduced Chronic Histopathology, R. Brian Stevens, Kirk W. Foster, Clifford D. Miles, Andre C. Kalil, Diana F. Florescu, John P. Sandoz, Theodore H. Rigley, Tamer Malik, Lucile E. Wrenshall

Department of Surgery Faculty Publications

Introduction

The two most significant impediments to renal allograft survival are rejection and the direct nephrotoxicity of the immunosuppressant drugs required to prevent it. Calcineurin inhibitors (CNI), a mainstay of most immunosuppression regimens, are particularly nephrotoxic. Until less toxic antirejection agents become available, the only option is to optimize our use of those at hand.

Aim

To determine whether intensive rabbit anti-thymocyte globulin (rATG) induction followed by CNI withdrawal would individually or combined improve graft function and reduce graft chronic histopathology–surrogates for graft and, therefore, patient survival. As previously reported, a single large rATG dose over 24 hours was well-tolerated …

Gene Diversification Of An Emerging Pathogen: A Decade Of Mutation In A Novel Fish Viral Hemorrhagic Septicemia (Vhs) Substrain Since Its First Appearance In The Laurentian Great Lakes, Carol A. Stepien, Lindsey R. Pierce, Douglas W. Leaman, Megan D. Niner, Brian S. Shepherd

Biological Sciences Faculty Publications

Viral Hemorrhagic Septicemia virus (VHSv) is an RNA rhabdovirus, which causes one of the world's most serious fish diseases, infecting >80 freshwater and marine species across the Northern Hemisphere. A new, novel, and especially virulent substrain—VHSv-IVb—first appeared in the Laurentian Great Lakes about a decade ago, resulting in massive fish kills. It rapidly spread and has genetically diversified. This study analyzes temporal and spatial mutational patterns of VHSv-IVb across the Great Lakes for the novel non-virion (Nv) gene that is unique to this group of novirhabdoviruses, in relation to its glycoprotein (G), phosphoprotein (P), …

Macroecology Of North American Suckers (Catostomidae): Tests Of Bergmann's And Rapoport's Rules, Stephen J. Jacquemin, Jason C. Doll

Biological Sciences Faculty Publications

Discerning spatial macroecological patterns in freshwater fishes has broad implications for community assembly, ecosystem dynamics, management, and conservation. This study explores the potential interspecific covariation of geographic range (Rapoport's rule) and body size (Bergmann's rule) with latitude in North American sucker fishes (Cypriniformes: Catostomidae). While numerous tests of Rapoport's and Bergmann's rules are documented in the literature, comparatively few of these studies have specifically tested for these patterns, and none have incorporated information reflecting shared ancestry into analyses of North American freshwater fish through a hierarchical model. This study utilized a hierarchical modeling approach with Bayesian inference to evaluate the …

Regulated Phosphorylation Of The K-Cl Cotransporter Kcc3 Is A Molecular Switch Of Intracellular Potassium Content And Cell Volume Homeostasis, Norma C. Adragna, Nagendra B. Ravilla, Peter K. Lauf, Gulnaz Begum, Arjun R. Khanna, Dandan Sun, Kristopher K. Kahle

Pharmacology and Toxicology Faculty Publications

The defense of cell volume against excessive shrinkage or swelling is a requirement for cell function and organismal survival. Cell swelling triggers a coordinated homeostatic response termed regulatory volume decrease (RVD), resulting in K+ and Cl− efflux via activation of K+ channels, volume-regulated anion channels (VRACs), and the K+-Cl− cotransporters, including KCC3. Here, we show genetic alanine (Ala) substitution at threonines (Thr) 991 and 1048 in the KCC3a isoform carboxyl-terminus, preventing inhibitory phosphorylation at these sites, not only significantly up-regulates KCC3a activity up to 25-fold in normally inhibitory isotonic conditions, but is also accompanied by reversal of activity of the …

Plastin 3 Expression Does Not Modify Spinal Muscular Atrophy Severity In The ∆7 Sma Mouse, Vicki L. Mcgovern, Aurelie Massoni-Laporte, Xueyong Wang, Thanh T. Le, Hao T. Le, Mark M. Rich, Arthur H. M. Burghes

Neuroscience, Cell Biology & Physiology Faculty Publications

Spinal muscular atrophy is caused by loss of the SMN1 gene and retention of SMN2. TheSMN2 copy number inversely correlates with phenotypic severity and is a modifier of disease outcome. The SMN2 gene essentially differs from SMN1 by a single nucleotide in exon 7 that modulates the incorporation of exon 7 into the final SMN transcript. The majority of the SMN2transcripts lack exon 7 and this leads to a SMN protein that does not effectively oligomerize and is rapidly degraded. However theSMN2 gene does produce some full-length SMN and theSMN2 copy number along with how …

The Significance Of Macrocephaly Or Enlarging Head Circumference In Infants With The Triad: Further Evidence Of Mimics Of Shaken Baby Syndrome, David Miller, Patrick Barnes, Marvin E. Miller

Pediatrics Faculty Publications

Infants with the triad (neurologic dysfunction, subdural hematoma [SDH], and retinal hemorrhage) are often diagnosed as victims of shaken baby syndrome. Medical conditions/predisposing factors to developing the triad are often dismissed: short falls, birth-related SDH that enlarges, macrocephaly, sinus/cortical vein thrombosis, and others. Six infants with the triad are described in which child abuse was diagnosed, but parents denied wrongdoing. All 6 had either macrocephaly or enlarging head circumference, which suggested medical explanations. Three infants incurred short falls, 1 had a difficult delivery in which there was likely a rebleed of a birth-related SDH, 1 had a spontaneous SDH associated …

Predictive Performance Of A Vancomycin Population Pharmacokinetic Model In Neonates, Chris Stockmann, Adam L. Hersh, Jessica K. Roberts, Jiraganya Bhongsatiern, E. Kent Korgenski, Michael G. Spigarelli, Catherine M.T. Sherwin, Adam Frymoyer

Pediatrics Faculty Publications

Introduction

The pharmacokinetics of vancomycin are highly variable among neonates, which makes dosing challenging in this population. However, adequate drug exposure is critical, especially when treating methicillin-resistant Staphylococcus aureus (MRSA) infections. Utilization of population pharmacokinetic models and Bayesian methods offers the potential for developing individualized therapeutic approaches. To meet this need, a neonatal vancomycin population pharmacokinetic model was recently published. The current study sought to externally evaluate the predictive performance and generalizability of this model.

Methods

A retrospective chart review of neonates who received vancomycin and had ≥1 peak and ≥1 trough concentrations at five Intermountain Healthcare neonatal intensive care …

The Effect Of Positive And Negative Reinforcement On Sixth Graders’ Mental Math Performance, Tess Greene, Amber Todd

Medical Education Faculty Publications

We examined the relationship between different forms of reinforcement and subjects’ mathematical performance. Thirty sixth-grade students were asked to mentally calculate answers to fraction problems, while holding a heart rate monitor, after receiving a positive, negative, or neutral form of reinforcement. While the results suggest that any motivation, positive or negative, may result in higher grades, the positive reinforcement group displayed the largest gain. However, the results were not statistically significant, though the trend was consistent with prior research. The heart rates of the positively-reinforced group were significantly lower than those of the negatively-reinforced and control groups. These results suggest …
