Brain and Mind Institute

Background: Souroubea sympetala Gilg. is a neotropical vine native to Central America, investigated as part of a targeted study of the plant family Marcgraviaceae. Our previous research showed that extract of S. sympetala leaf and small branch extract had anxiolytic effects in animals and acts as an agonist for the GABAA receptor at the benzodiazepine binding site. To date, the potential effects of S. sympetala and its constituents on reconsolidation have not been assessed. Reconsolidation, the process by which formed memories are rendered labile and susceptible to change, may offer a window of opportunity for pharmacological manipulation of learned fear. …

Acne Severity And Sleep Quality In Adults., Kory P Schrom, Sayeeda Ahsanuddin, Michelle Baechtold, Raghav Tripathi, Amy Ramser, Elma Baron

Ambulatory and Primary Care Articles

Poor sleep quality is extremely prevalent, with about one third of adults in the USA obtaining less than the recommended amount of sleep. In addition, poor sleep quality has been linked to an increased risk of many conditions, including diabetes, hypertension, psychiatric conditions, and overall all-cause mortality. Research has shown that sleep disturbance does impact skin disease, although many details of this relationship are still unclear. The goal of this study is to determine if there is a relationship between acne severity and sleep quality in adults. Forty subjects with acne were recruited from dermatology clinics in Cleveland, OH, to …

Identification Of The Kaposi's Sarcoma-Associated Herpesvirus (Kshv) Surface Glycoprotein Targets Of Human Kshv-Specific Neutralizing Antibody Responses, Yasaman Mortazavi

School of Biological Sciences: Dissertations, Theses, and Student Research

Kaposi’s sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV-8), is the etiological agent of Kaposi’s sarcoma (KS), and is also associated with two B cell malignancies, primary effusion lymphoma and multicentric Castleman's disease. The distribution of KSHV varies globally with high prevalence in some areas of sub-Saharan Africa (SSA), where seroprevalence can be as high as 80%. It is estimated that nearly 44,000 new cases of KS emerge annually globally, with the highest incidents occurring in Africa, where KSHV is endemic. Currently, there is no prophylactic vaccine against KSHV, and efforts to develop prophylactic vaccines have been limited. …

The Effects Of Nicotine And Cigarette Smoking On Cardiac Electrophysiology., Affan B. Irfan

New Insights Into The Lactate Shuttle: Role Of Mct4 In The Modulation Of The Exercise Capacity., Sara Bisetto, Megan C Wright, Romana A Nowak, Angelo C Lepore, Tejvir S Khurana, Emanuele Loro, Nancy J Philp

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Lactate produced by muscle during high-intensity activity is an important end product of glycolysis that supports whole body metabolism. The lactate shuttle model suggested that lactate produced by glycolytic muscle fibers is utilized by oxidative fibers. MCT4 is a proton coupled monocarboxylate transporter preferentially expressed in glycolytic muscle fibers and facilitates the lactate efflux. Here we investigated the exercise capacity of mice with disrupted lactate shuttle due to global deletion of MCT4 (MCT4−/−) or muscle-specific deletion of the accessory protein Basigin (iMSBsg−/−). Although MCT4−/− and iMSBsg−/− mice have normal muscle morphology and contractility, only MCT4−/− mice exhibit an exercise intolerant …

Haptoglobin Genotyping And Risk Of Cerebral Vasospasm After Aneurysmal Subarachnoid Hemorrhage, Ahmed M. Ateya, Ahmed A. El-Bassiouny, Islam El-Garwany, Khaled Gobbah, Mahmoud H. Ibrahim, Nagia A. Fahmy, Sobhy H. El-Nabi

Journal of Medicine in Scientific Research

Background Aneurysmal subarach noid hemorrhage (aSAH) represents roughly 6–8% of all stroke types. Almost 70% of patients develop angiographic vasospasm, and 30% of them will have delayed cerebral ischemia (DCI). An 'omic signature' could combine genetic, proteomic, and metabolomic phenotypes into an accurate predictive model. Haptoglobin (Hp) genotypes could be used to stratify risk of resulting cerebral vasospasm (CV) and DCI, to give prognostic data dependent on distributed result probabilities, and to develop novel medications dependent on individual pathophysiological models. Objective This research intends to investigate the clinical and radiological factors as indicators for risk of development of CV after …

Elevated Glucose Acts Directly On Osteocytes To Increase Sclerostin Expression In Diabetes, Donna M. Pacicca, Tammy Brown, Dara Watkins, Karen Kover, Yun Yan, Matthew Prideaux, Lynda Bonewald

Manuscripts, Articles, Book Chapters and Other Papers

© 2019, The Author(s).

Bone quality in diabetic patients is compromised, leading to weaker bones and increased fracture risk. However, the mechanism by which this occurs in diabetic bone remains to be fully elucidated. We hypothesized that elevated glucose and glucose variation would affect the function of osteocytes, essential regulators of bone homeostasis and quality. To first test this hypothesis, we used the IDG-SW3 osteocyte-like cell line to examine the effects of glucose levels on osteocyte function and viability in vitro. We confirmed our in vitro findings using the in vivo streptozotocin-induced (STZ) diabetic rat model and ex-vivo cultured osteocytes …

Peritumoral Administration Of Dribbles-Pulsed Antigen-Presenting Cells Enhances The Antitumor Efficacy Of Anti-Gitr And Anti-Pd-1 Antibodies Via An Antigen Presenting Independent Mechanism., Jaina M Patel, Zhihua Cui, Zhi-Fa Wen, Catherine T Dinh, Hong-Ming Hu

Articles, Abstracts, and Reports

BACKGROUND: TNF receptor family agonists and checkpoint blockade combination therapies lead to minimal tumor clearance of poorly immunogenic tumors. Therefore, a need to enhance the efficacy of this combination therapy arises. Antigen-presenting cells (APCs) present antigen to T cells and steer the immune response through chemokine and cytokine secretion. DRibbles (DR) are tumor-derived autophagosomes containing tumor antigens and innate inflammatory adjuvants.

METHODS: Using preclinical murine lung and pancreatic cancer models, we assessed the triple combination therapy of GITR agonist and PD-1 blocking antibodies with peritumoral injections of DRibbles-pulsed-bone marrow cells (BMCs), which consisted mainly of APCs, or CD103+ cross-presenting dendritic …

Department of Pathology and Laboratory Medicine

Campylobacter species infections have been associated with malnutrition and intestinal inflammation among children in low-resource settings. However, it remains unclear whether that association is specific to Campylobacter jejuni/coli. The aim of this study was to assess the association between both all Campylobacter species infections and Campylobacter jejuni/coli infections on growth and enteric inflammation in children aged 1-24 months. We analyzed data from 1715 children followed from birth until 24 months of age in the MAL-ED birth cohort study, including detection of Campylobacter species by enzyme immunoassay and Campylobacter jejuni/coli by quantitative PCR in stool samples. Myeloperoxidase (MPO) concentration in stool, …

Role Of Probiotics In Non-Alcoholic Fatty Liver Disease: Does Gut Microbiota Matter?, Chencheng Xie, Dina Halegoua-De Marzio

Division of Gastroenterology and Hepatology Faculty Papers

Non-alcoholic fatty liver disease (NAFLD) is the hepatic consequence of metabolic syndrome, which often also includes obesity, diabetes, and dyslipidemia. The connection between gut microbiota (GM) and NAFLD has attracted significant attention in recent years. Data has shown that GM affects hepatic lipid metabolism and influences the balance between pro/anti-inflammatory effectors in the liver. Although studies reveal the association between GM dysbiosis and NAFLD, decoding the mechanisms of gut dysbiosis resulting in NAFLD remains challenging. The potential pathophysiology that links GM dysbiosis to NAFLD can be summarized as: (1) disrupting the balance between energy harvest and expenditure, (2) promoting hepatic …

Defining The Layers Of A Sensory Cilium With Storm And Cryoelectron Nanoscopy, Michael A Robichaux, Valencia L Potter, Zhixian Zhang, Feng He, Jun Liu, Michael F Schmid, Theodore G Wensel

Faculty, Staff and Students Publications

Primary cilia carry out numerous signaling and sensory functions, and defects in them, "ciliopathies," cause a range of symptoms, including blindness. Understanding of their nanometer-scale ciliary substructures and their disruptions in ciliopathies has been hindered by limitations of conventional microscopic techniques. We have combined cryoelectron tomography, enhanced by subtomogram averaging, with superresolution stochastic optical reconstruction microscopy (STORM) to define subdomains within the light-sensing rod sensory cilium of mouse retinas and reveal previously unknown substructures formed by resident proteins. Domains are demarcated by structural features such as the axoneme and its connections to the ciliary membrane, and are correlated with molecular …

Edwards, Raymond Wong, Ivana Rajkovic, Amanda L. Trout, Abir A. Rahman, Samantha Hamilton, Justin F. Fraser, Emmanuel Pinteaux, Gregory J. Bix

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Stroke remains a leading cause of death and disability worldwide despite recent treatment breakthroughs. A primary event in stroke pathogenesis is the development of a potent and deleterious local and peripheral inflammatory response regulated by the pro-inflammatory cytokine interleukin-1 (IL-1). While the role of IL-1β (main released isoform) has been well studied in stroke, the role of the IL-1α isoform remains largely unknown. With increasing utilization of intravenous tissue plasminogen activator (t-PA) or thrombectomy to pharmacologically or mechanically remove ischemic stroke causing blood clots, respectively, there is interest in pairing successful cerebrovascular recanalization with neurotherapeutic pharmacological interventions (Fraser et …

RECENT FINDINGS: Several randomized controlled trials have been published in the past 4 years that concluded transdermal lidocaine can reduce acute pain associated with laparoscopic trocar or cannula insertion. Transdermal lidocaine may reduce short-term pain after surgery in selected surgery types and has a low risk of toxicity but its overall clinical utility in the …

Prognostic Value Of Neutrophil-Lymphocyte Ratio In Patients With Severe Alcoholic Hepatitis., Yazan Abu Omar, Tejinder Randhawa, Bashar Attar, Rohit Agrawal, Yuchen Wang, Rayli Pichardo, Muhammad B Majeed, Sanjay A Patel

Ambulatory and Primary Care Articles

Background Prednisolone is considered the cornerstone treatment for severe alcoholic hepatitis (AH). However, its use is limited by the increased risk of infection in an already immunocompromised patient population. Among patients with severe AH, there exists a group of non-responders who do not benefit from prednisolone therapy. Day-4 Lille score is a widely employed prognostic model used to identify this non-responder subgroup. The present study evaluates the prognostic ability of the inflammatory marker, the neutrophil-lymphocyte ratio (NLR), as a stand-alone model and in conjunction with the day-4 Lille score. Methods We retrospectively reviewed the electronic medical records of patients diagnosed …

Genome-Wide Variation In Potyviruses, Deepti Nigam, Katherine Latourrette, Pedro F.N. Souza, Hernan Garcia Ruiz

Nebraska Center for Virology: Faculty Publications

Potyviruses (family Potyviridae, genus Potyvirus) are the result of an initial radiation event that occurred 6,600 years ago. The genus currently consists of 167 species that infect monocots or dicots, including domesticated and wild plants. Potyviruses are transmitted in a non-persistent way by more than 200 species of aphids. As indicated by their wide host range, worldwide distribution, and diversity of their vectors, potyviruses have an outstanding capacity to adapt to new hosts and environments. However, factors that confer adaptability are poorly understood. Viral RNA-dependent RNA polymerases introduce nucleotide substitutions that generate genetic diversity. We hypothesized that selection imposed by …

Natural hosts of simian immunodeficiency virus (SIV) avoid AIDS despite lifelong infection. Here, we examined how this outcome is achieved by comparing a natural SIV host, African green monkey (AGM) to an AIDS susceptible species, rhesus macaque (RM). To asses gene expression profiles from acutely SIV infected AGMs and RMs, we developed a systems biology approach termed Conserved Gene Signature Analysis (CGSA), which compared RNA sequencing data from rectal AGM and RM tissues to various other species. We found that AGMs rapidly activate, and then maintain, evolutionarily conserved regenerative wound healing mechanisms in mucosal tissue. The wound healing protein fibronectin …

Apasl Hcv Guidelines Of Virus-Eradicated Patients By Daa On How To Monitor Hcc Occurrence And Hbv Reactivation, Tatsuo Kanda, George K K. Lau, Lai Wei, Mitsuhiko Moriyama, Ming-Lung Yu, Wang-Long Chuang, Alaaeldin Ibrahim, Cosmas Rinaldi Adithya Lesmana, Saeed Hamid, Wasim Jafri

Section of Gastroenterology

In the direct-acting antiviral (DAA) era for hepatitis C virus (HCV) infection, sustained virological response (SVR) is very high, but close attention must be paid to the possible occurrence of hepatocellular carcinoma (HCC) and reactivation of hepatitis B virus (HBV) in patients with co-infection who achieved SVR in short term. HCC occurrence was more often observed in patients with previous HCC history. We found occurrence of HCC in 178 (29.6%) of 602 patients with previous HCC history (15.4 months mean follow-up post-DAA initiation) but, in contrast, in only 604 (1.3%) of 45,870 patients without previous HCC history (18.2 months mean …

A Physiologically-Based Pharmacokinetic Model For Targeting Calcitriol-Conjugated Quantum Dots To Inflammatory Breast Cancer Cells., James Forder, Mallory Smith, Margot Wagner, Rachel J. Schaefer, Jonathan Gorky, Kenneth L. Van Golen, Anja Nohe, Prasad Dhurjati

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Quantum dots (QDs) conjugated with 1,25 dihydroxyvitamin D3 (calcitriol) and Mucin-1 (MUC-1) antibodies (SM3) have been found to target inflammatory breast cancer (IBC) tumors and reduce proliferation, migration, and differentiation of these tumors in mice. A physiologically-based pharmacokinetic model has been constructed and optimized to match experimental data for multiple QDs: control QDs, QDs conjugated with calcitriol, and QDs conjugated with both calcitriol and SM3 MUC1 antibodies. The model predicts continuous QD concentration for key tissues in mice distinguished by IBC stage (healthy, early-stage, and late-stage). Experimental and clinical efforts in QD treatment of IBC can be augmented by in …
