In Vivo Brainstem Imaging In Alzheimer’S Disease: Potential For Biomarker Development, David J. Braun, Linda J. Van Eldik

Neuroscience Faculty Publications

The dearth of effective treatments for Alzheimer’s disease (AD) is one of the largest public health issues worldwide, costing hundreds of billions of dollars per year. From a therapeutic standpoint, research efforts to date have met with strikingly little clinical success. One major issue is that trials begin after substantial pathological change has occurred, and it is increasingly clear that the most effective treatment regimens will need to be administered earlier in the disease process. In order to identify individuals within the long preclinical phase of AD who are likely to progress to dementia, improvements are required in biomarker development. …

Virus-infected cells can regulate non-permissive bystander cells, but the precise mechanisms remain incompletely understood. Here we report that this process can be mediated by transfer of viral RNA-loaded exosomes shed from infected cells to myeloid-derived suppressor cells (MDSCs), which in turn regulate the differentiation and function of T cells during viral infection. Specifically, we demonstrated that patients with chronic hepatitis C virus (HCV) infection exhibited significant increases in T follicular regulatory (TFR) cells and decreases in T follicular helper (TFH) cells. These MDSC-mediated T-cell dysregulations resulted in an increased ratio of TFR/TFH and IL-10 production in peripheral blood. Specifically, co-culture …

Susceptibility Genes To Plant Viruses, Hernan Garcia-Ruiz

Nebraska Center for Virology: Faculty Publications

Plant viruses use cellular factors and resources to replicate and move. Plants respond to viral infection by several mechanisms, including innate immunity, autophagy, and gene silencing, that viruses must evade or suppress. Thus, the establishment of infection is genetically determined by the availability of host factors necessary for virus replication and movement and by the balance between plant defense and viral suppression of defense responses. Host factors may have antiviral or proviral activities. Proviral factors condition susceptibility to viruses by participating in processes essential to the virus. Here, we review current advances in the identification and characterization of host factors …

Pregnancy Anxiety Predicts Shorter Gestation In Latina And Non-Latina White Women: The Role Of Placental Corticotrophin-Releasing Hormone, Isabel F. Ramos, Christine M. Guardino, Maxwell Mansolf, Laura M. Glynn, Curt A. Sandman, Calvin J. Hobel, Christine Dunkel Schetter

Psychology Faculty Articles and Research

Objective

Previous research has shown that a woman’s anxiety about her pregnancy predicts gestational length. Placental corticotrophin-releasing hormone (CRH) is a stress-responsive peptide proposed as a mechanism. We examined placental CRH as a physiological mediator of the association between pregnancy anxiety and gestational length in Latina and non-Latina White women to replicate evidence of associations between pregnancy anxiety, placental CRH and gestational length; to test whether placental CRH levels or changes mediate effects of pregnancy anxiety on gestational length; to examine ethnic differences in pregnancy anxiety, placental CRH, and gestational length; and to explore whether the effects of pregnancy anxiety …

"Born Out Of Fear": A Grounded Theory Study Of The Stigma Of Bipolar Disorder For New Mothers, Walker Ladd Ph.D.

The Qualitative Report

Childbirth is an established trigger for the onset of bipolar disorders (BD) in the postpartum period, causing significant pathology and disability. Research has shown that the stigma of mental illness for new mothers is a powerful obstacle to care, preventing women from accessing critical treatment and social support. However, the majority of research has examined the relationship between the stigma and postpartum depression, leaving a gap in knowledge regarding stigma and postpartum bipolar disorder. The problem addressed in this grounded theory study was the lack of knowledge regarding the stigma of a diagnosis of bipolar disorder (BD) in the first …

Effects Of Beta Blockers And Ace Inhibitors After Left Ventricular Assist Device Implantation, Gaurang Vaidya, Emma Birks, Jessica Pillarella, Benjamin Salgado, Rajakrishnan Vijayakrishnan, Andrew Lenneman, Mark Slaughter, Dmitry Abramov

The VAD Journal

Purpose: While Beta blockers(BB) and Angiotensin system blockers(ACEinh/ARB) are important components in advanced heart failure therapy, their use after left ventricular assist device (LVAD) implantation remains controversial. Concern has been raised about possible adverse effects of BB on right ventricular(RV) function while tolerance and efficacy/outcome data for ACEinh are lacking. This study aimed to characterize the use of medical therapy post-LVAD implantation and to evaluate its safety and efficacy. Methods: Demographic, clinical and echocardiographic variables of patients implanted with a continuous-flow LVAD between 2012 and 2015 at a single center were retrospectively reviewed. Mortality and heart failure(CHF) hospitalizations were followed …

Transcriptional Up-Regulation Of Relaxin-3 By Nur77 Attenuates Β-Adrenergic Agonist-Induced Apoptosis In Cardiomyocytes., Xiaohua You, Zhifu Guo, Fang Cheng, Bing Yi, Fan Yang, Xinzhu Liu, Ni Zhu, Xianxian Zhao, Guijun Yan, Xin-Liang Ma, Jianxin Sun

Center for Translational Medicine Faculty Papers

The relaxin family peptides have been shown to exert several beneficial effects on the heart, including anti-apoptosis, anti-fibrosis, and anti-hypertrophy activity. Understanding their regulation might provide new opportunities for therapeutic interventions, but the molecular mechanism(s) coordinating relaxin expression in the heart remain largely obscured. Previous work demonstrated a role for the orphan nuclear receptor Nur77 in regulating cardiomyocyte apoptosis. We therefore investigated Nur77 in the hopes of identifying novel relaxin regulators. Quantitative real-time PCR (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) data indicated that ectopic expression of orphan nuclear receptor Nur77 markedly increased the expression of latexin-3 (RLN3), but not relaxin-1 …

Background

Myotonic Dystrophy is the most common form of muscular dystrophy in adults, affecting an estimated 10 per 100,000 people. It is a multisystemic disorder affecting multiple generations with increasing severity. There are currently no licenced therapies to reverse, slow down or cure its symptoms. In 2009 TREAT-NMD (a global alliance with the mission of improving trial readiness for neuromuscular diseases) and the Marigold Foundation held a workshop of key opinion leaders to agree a minimal dataset for patient registries in myotonic dystrophy. Eight years after this workshop, we surveyed 22 registries collecting information on myotonic dystrophy patients to assess …

T cells play a crucial role in viral clearance and vaccine responses; however, the mechanisms that regulate their homeostasis during viral infections remain unclear. In this study, we investigated the machineries of T-cell homeostasis and telomeric DNA damage using a human model of hepatitis C virus (HCV) infection. We found that naïve CD4 T cells in chronically HCV-infected patients (HCV T cells) were significantly reduced due to apoptosis compared with age-matched healthy subjects (HSs). These HCV T cells were not only senescent, as demonstrated by overexpression of aging markers and particularly shortened telomeres; but also DNA damaged, as evidenced by …

Life Review In Aging: A Primer, Thomas M. Meuser

Social Work Faculty Publications

Humans are narrative beings. We understand and speak of ourselves and the events of our lives in the context of stories. The stories we tell are influenced by our lived experiences, the quality of our memories (what’s recalled and forgotten), relationships, personality styles, values, accomplishments, regrets, spiritual beliefs, and a host of other factors. Telling our stories from the vantage point of old age is reflective of a maturational process of introspection and discovery called life review.

Variations Of The Transverse Sinus: Review With An Unusual Case Report., Chrissie Massrey, Juan J Altafulla, Joe Iwanaga, Zachary Litvack, Basem Ishak, Rod J Oskouian, Marios Loukas, R Shane Tubbs

Articles, Abstracts, and Reports

The dural venous sinuses are venous channels in the cranium that drain blood and cerebrospinal fluid circulating from the brain into the vascular system via the internal jugular veins. The transverse sinus is a dural venous sinus present in the posterior aspect of the cranium. We report an unusual variant of this sinus with the presence of a fenestration at its proximal segment. We will review and discuss the background and the potential clinical relevance of this anatomical variation.

Department of Medical Oncology Faculty Papers

For a long time, pioneers in the field of cancer cell metabolism, such as Otto Warburg, have focused on the idea that tumor cells maintain high glycolytic rates even with adequate oxygen supply, in what is known as aerobic glycolysis or the Warburg effect. Recent studies have reported a more complex situation, where the tumor ecosystem plays a more critical role in cancer progression. Cancer cells display extraordinary plasticity in adapting to changes in their tumor microenvironment, developing strategies to survive and proliferate. The proliferation of cancer cells needs a high rate of energy and metabolic substrates for biosynthesis of …

Patients with epidermodysplasia verruciformis (EV) and biallelic null mutations of TMC6 (encoding EVER1) or TMC8 (EVER2) are selectively prone to disseminated skin lesions due to keratinocyte-tropic human β-papillomaviruses (β-HPVs), which lack E5 and E8. We describe EV patients homozygous for null mutations of the CIB1 gene encoding calcium- and integrin-binding protein-1 (CIB1). CIB1 is strongly expressed in the skin and cultured keratinocytes of controls but not in those of patients. CIB1 forms a complex with EVER1 and EVER2, and CIB1 proteins are not expressed in EVER1- or EVER2-deficient cells. The known functions of EVER1 and EVER2 in human keratinocytes are …

Purpose: Loss of cell-cycle control is a hallmark of cancer, which can be targeted with agents, including cyclin-dependent kinase-4/6 (CDK4/6) kinase inhibitors that impinge upon the G₁-S cell-cycle checkpoint via maintaining activity of the retinoblastoma tumor suppressor (RB). This class of drugs is under clinical investigation for various solid tumor types and has recently been FDA-approved for treatment of breast cancer. However, development of therapeutic resistance is not uncommon.

Experimental Design: In this study, palbociclib (a CDK4/6 inhibitor) resistance was established in models of early stage, RB-positive cancer.

Results: This study demonstrates that acquired palbociclib resistance renders cancer …

Role Of Palliative Csf Diversion In Patients With Intracranial Metastatic Disease And Symptomatic Hydrocephalus, Farhan A. Mirza, Muhammad Shahzad Shamim

Section of Neurosurgery

Hydrocephalus, unless treated, is one of the terminal manifestations of intracranial metastatic disease. Single lesions causing obstructive hydrocephalus are amenable to surgical resection, but in the setting of multiple lesions and communicating hydrocephalus from leptomeningeal disease, the approach to treatment is much less defined. The use of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunting (VPS) has been described, but data is limited. In this review, we summarize the sparse data available in literature describing the use of CSF diversion for patients with metastatic disease presenting with hydrocephalus and neurological decline.

Section of Diabetes, Endocrinology and Metabolism

We present a family with 2 members who received long-term steroid treatment for presumed classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, until molecular testing revealed nonclassic CAH, not necessarily requiring treatment. A 17-year-old male presented to our clinic on glucocorticoid and mineralocorticoid treatment for classic CAH. He was diagnosed at 4 years of age based on mild-moderate elevations of 17-hydroxyprogesterone (17-OHP) and adrenocorticotropic hormone (ACTH), but without evidence of precocious adrenarche/puberty. Due to his diagnosis, his clinically asymptomatic 3-year-old sister was tested and also found to have elevated ACTH and 17-OHP levels and was started on glucocorticoids for …

Bilateral Psoas Abscess After Extracorporeal Shock Wave Lithotripsy: Reminder Of A Rare Complication, Sidra Zafar, Syed Usman Bin Mahmood, Arsal Tharwani, Noreen Nasir

Section of Nephrology

Extracorporeal shock wave lithotripsy (ESWL) is among the most widely used modalities for treatment of urolithiasis since its introduction in the 1980s. The non-invasive technique reduces the risk of post-procedure complications and produces excellent stone free rates. However, complications may still follow and albeit rare, there are reports in literature of abscess formation post ESWL. Herein, we report the case of a young, immunocompetent gentleman who developed bilateral psoas abscess after undergoing this procedure. He was successfully managed at our institute with intravenous antibiotics, percutaneous abscess drainage and was discharged on day 5 post-intervention in a stable condition. There have …

Leighton Grimes

Department of Cancer Biology Faculty Papers

We have shown that antagomiR inhibition of miRNA miR-21 and miR-196b activity is sufficient to ablate MLL-AF9 leukemia stem cells (LSC) in vivo. Here, we used an shRNA screening approach to mimic miRNA activity on experimentally verified miR-196b targets to identify functionally important and therapeutically relevant pathways downstream of oncogenic miRNA in MLL-r AML. We found Cdkn1b (p27^Kip1) is a direct miR-196b target whose repression enhanced an embryonic stem cell–like signature associated with decreased leukemia latency and increased numbers of leukemia stem cells in vivo. Conversely, elevation of p27^Kip1 significantly reduced MLL-r leukemia self-renewal, promoted monocytic differentiation …
