Cell-Cycle Regulatory Proteins In The Podocyte In Collapsing Glomerulopathy In Children., Tarak Srivastava, Robert E. Garola, H K. Singh

Manuscripts, Articles, Book Chapters and Other Papers

Podocyte is a terminally committed cell in G1 arrest of cell cycle, and is unable to overcome G1/S transition phase in children with minimal change disease (MCD) and classic focal segmental glomerulosclerosis (FSGS), in contrast to dysregulated proliferative phenotype of idiopathic collapsing glomerulopathy (CGN) in adults. Forty-two kidney biopsies, MCD (14), FSGS (12), CGN (4), and normal (CON) (12), were evaluated by immunohistochemistry using dual staining for expression of p27, p21, and p57, and cyclins D and A, in podocytes of children with CGN. On light microscopy, all podocytes expressed p27, whereas p21 and p57 expression was seen in a …

The Acute Effects Of Nut Ingestion On Plasma Levels Of Polyphenol Compounds, Biomarkers Of Antioxidant Status, And Lipid Peroxidation, Setareh Torabian Esfahani

Nuts are rich sources of polyphenolic compounds and nutrients, which have antioxidant capacity. To assess the acute effect of treatment diet (75% of energy from nuts (walnut or almond) and control diet (habitual diet with no nut consumption) in healthy subjects on plasma total phenol content, antioxidant capacity and plasma lipid peroxidation. Thirteen subjects participated in the crossover design study. After an overnight fast, walnut, almond and a control diet, in form of smoothies, were consumed by the study subjects. Each subject participated on three occasions one week apart, consuming one of the smoothies each time. Blood samples were obtained …

Peritoneal Perfusion With Oxygenated Perfluorocarbon Augments Systemic Oxygenation., Shamus R Carr, Joshua P Cantor, Atul S Rao, Thiru V Lakshman, Joshua E Collins, Joseph S Friedberg

Department of Surgery Faculty Papers

BACKGROUND: Despite maximal ventilatory support, many patients die from hypoxia in the setting of potentially reversible pulmonary failure. There remains a pressing need for additional pulmonary supportive care measures, especially techniques that do not require systemic anticoagulation. The objective of our experiments was to determine whether systemic oxygenation could be increased in a large animal, with induced hypoxia, by perfusing the abdominal cavity with oxygenated perfluorocarbons.

METHODS: Fifteen pigs with a mean (+/- SD) weight of 45 +/- 5 kg were intubated and rendered hypoxic by ventilating them with a blend of nitrogen and oxygen to achieve subatmospheric concentrations of …

Role Of A2b Adenosine Receptor Signaling In Adenosine-Dependent Pulmonary Inflammation And Injury, Chun-Xiao Sun, Hongyan Zhong, Amir Mohsenin, Eva Morschl, Janci L Chunn, Jose G Molina, Luiz Belardinelli, Dewan Zeng, Michael R Blackburn

Faculty, Staff and Student Publications

Adenosine has been implicated in the pathogenesis of chronic lung diseases such as asthma and chronic obstructive pulmonary disease. In vitro studies suggest that activation of the A2B adenosine receptor (A2BAR) results in proinflammatory and profibrotic effects relevant to the progression of lung diseases; however, in vivo data supporting these observations are lacking. Adenosine deaminase-deficient (ADA-deficient) mice develop pulmonary inflammation and injury that are dependent on increased lung adenosine levels. To investigate the role of the A2BAR in vivo, ADA-deficient mice were treated with the selective A2BAR antagonist CVT-6883, and pulmonary inflammation, fibrosis, and airspace integrity were assessed. Untreated and …

Orr, Claudia Roberts, Kikkeri N. Naresh, El-Nasir Lalani, David J. Mann, Roger J. Watson, N. Shaun B. Thomas, Eric W. -F. Lam

Department of Pathology and Laboratory Medicine

To investigate the potential functional cooperation between p27^Kip1 and p130 in vivo, we generated mice deficient for both p27^Kip1 and p130. In p27^Kip1−/−;p130^−/− mice, the cellularity of the spleens but not the thymi is significantly increased compared with that of their p27^Kip1−/− counterparts, affecting the lymphoid, erythroid, and myeloid compartments. In vivo cell proliferation is significantly augmented in the B and T cells, monocytes, macrophages, and erythroid progenitors in the spleens of p27^Kip1−/−; p130^−/− animals. Immunoprecipitation and immunodepletion studies indicate that p130 can compensate for the absence …

Preventive Treatment Of Migraine, Stephen Silberstein

Department of Neurology Faculty Papers

Migraine is a common episodic pain disorder, the treatment of which can be acute to stop an attack or preventive to reduce the frequency, duration or severity of attacks. Preventive treatment is used when attacks are frequent or disabling. Many different medication groups are used for preventive treatment, including β-blockers, antidepressants and antiepileptic drugs. Their mechanisms of action include raising the threshold to migraine activation, enhancing antinociception, inhibiting cortical spreading depression, inhibiting peripheral and central sensitization, blocking neurogenic inflammation and modulating sympathetic, parasympathetic or 5-HT tone. In this article, I review evidence of the effectiveness of migraine preventive drugs. I …

Don't Bring Me Your Tired, Your Poor: The Crowded State Of America's Emergency Departments, Jessamyn Taylor

National Health Policy Forum

If the time comes, people expect that the emergency department (ED) will have the resources necessary to treat them in a timely, high-quality manner. Increasingly, however, EDs may not be able to meet that expectation. Hospitals in urban areas with large populations, high population growth, and higher-than-average numbers of uninsured are particularly crowded: ambulances are often diverted to other hospitals and patients are frequently forced to “board” in the hallways (while they wait to be transferred to another facility or part of the hospital). This issue brief places EDs in the context of the U.S. health care system and its …

The Effect Of Hus1 On Ionizing Radiation Sensitivity Is Associated With Homologous Recombination Repair But Is Independent Of Non-Homologous End-Joining, Robert S. Weiss, Xiang Wang, Baocheng Hu, Ya Wang

Department of Radiation Oncology Faculty Papers

Mammalian Hus1 plays an important role in maintaining genomic integrity. Cells lacking mouse Hus1 are hypersensitive to DNA damage inducers including UV and camptothecin (CPT). By using clonogenic assay, we show here that Hus1 deficient mouse cells are hypersensitive to ionizing radiation (IR) compared with their Hus1-positive counterparts. However, these cells show similar induction levels and similar rejoining rates of DNA double strand breaks (DSBs) following IR, indicating that the effect of Hus1 on cell radiosensitivity is independent of non-homologous end-joining (NHEJ). By combining an I-SceI-induced-DNA DSBs system and a siRNA approach, we also show that knocking down Hus1 decreases …

Brain Tumor Stem Cells: Role In Neuro-Oncogenesis And Therapeutic Implications, Muhammad Zeeshan Ozair, Adil Hameed Khan, Ather Enam

Department of Biological & Biomedical Sciences

Malignant brain tumors are notorious for high morbidity and mortality. Our deficient understanding of brain tumor pathogenesis is reflected in our inability to cure this disease. Treatment remains palliative at best. The cancer stem cell hypothesis of brain tumors promises to consolidate many observations which have previously eluded neuroscientists and may reveal why aberrations in developmental programs are among the commonest findings in brain tumors. It is ironic that brain ontogeny and cancer - two processes with very different outcomes - exploit similar mechanisms to multiply, migrate,and survive. Implications of this hypothesis extend beyond mere academic interest. It may explain …

Tuberculosis Of The Scapula, Yousuf A. Husen, Naila Nadeem, Fawad Aslam, Muhammad Ali Shah

Department of Radiology

Tuberculosis (TB) of the scapula is an extremely rare presentation of osteoarticular tuberculosis. In a tuberculosis endemic setting with a rising burden of acquired immunodeficiency syndrome, this rare presentation may become more frequent. The common presentation is with longstanding Complaints of pain and swelling in the shoulder region, typically in young adults. Classic radiographic features include a well defined radiolucent lesion with minimal sequesteration. The erythrocyte sedimentation rate is usually elevated and initially these patients are frequently mis-diagnosed and thus a high index of clinical suspicion is required. Medical therapy with antituberculous drugs is the standard modality of treatment. This …

Comparison Of Dynamic (Brush) And Static (Pressure) Mechanical Allodynia In Migraine, C. Lopinto, W. B. Young, Avi Ashkenazi

Department of Neurology Faculty Papers

Allodynia has been described in migraine but has not been fully investigated for the different sensory modalities. The aim of this study was to compare the prevalence of dynamic (brush) and static (pressure) mechanical allodynia in migraine patients and to suggest a practical method of testing them in a clinical setting. Patients with International Headache Society-defined episodic migraine (EM) or with transformed migraine (TM) as defined by Silberstein and Lipton were prospectively recruited from the Jefferson Headache Center out-patient clinic. A questionnaire of migraine features and symptoms of allodynia was administered. Brush allodynia (BA) was tested by cutaneous stimulation with …

Nebraska Center for Virology: Faculty Publications

The genetic diversity among globally circulating human immunodeficiency virus type 1 (HIV-1) strains is a serious challenge for HIV-1 vaccine design. We have generated a synthetic groupMconsensus env gene (CON6) for induction of cross-subtype immune responses and report here a comparative study of T-cell responses to this and natural strain env immunogens in a murine model. Three different strains of mice were immunized with CON6 as well as subtype A, B, or C env immunogens, using a DNA prime-recombinant vaccinia virus boost strategy. T-cell epitopes were mapped by gamma interferon enzyme-linked immunospot analysis using five overlapping Env peptide sets from …

Transcriptional Regulation Of The Borrelia Burgdorferi Antigenically Variable Vlse Surface Protein, Tomasz Bykowski, Kelly Babb, Kate Von Lackum, Sean P Riley, Steven J Norris, Brian Stevenson

Faculty, Staff and Student Publications

The Lyme disease agent Borrelia burgdorferi can persistently infect humans and other animals despite host active immune responses. This is facilitated, in part, by the vls locus, a complex system consisting of the vlsE expression site and an adjacent set of 11 to 15 silent vls cassettes. Segments of nonexpressed cassettes recombine with the vlsE region during infection of mammalian hosts, resulting in combinatorial antigenic variation of the VlsE outer surface protein. We now demonstrate that synthesis of VlsE is regulated during the natural mammal-tick infectious cycle, being activated in mammals but repressed during tick colonization. Examination of cultured B. …

Systemic Mastocytosis: A Rare Entity, Naveen Naz Syed, Bushra Moiz

Department of Pathology and Laboratory Medicine

An 18 year old female presented with generalized maculopapular rash and headaches. The skin and bone marrow biopsy revealed numerous mast cells which stained metachromatically with giemsa and toludine blue stains and showed positivity with CD68 and CD117 on immunohistochemistry. Her clinical presentation and laboratory findings were consistent with the diagnosis of indolent systemic mastocytosis. Because of the benign course of the disease, patient was offered only anti-histamine drugs that were quite successful in alleviating her symptoms.

Correlation Between Number Of Retrieved Oocytes And Pregnancy Rate After In Vitro Fertilization/Intracytoplasmic Sperm Infection, Tanya Timeva, Tanya Milachich, Irena Antonova, Tanya Arabaji, Atanas Shterev, Hatim A. Omar

Pediatrics Faculty Publications

The implementation of safe and maximally effective ovarian stimulation is a major aim for in vitro fertilization (IVF) teams. The goal of controlled ovarian hyperstimulation (COH) is to supply enough oocytes with normal maturation to insure the consequent biological procedures. A variety of different stimulation protocols have been suggested and an individual selection of the correct stimulation protocol is mandatory. The aim of the present study is to evaluate the correlation between number of retrieved oocytes and clinical pregnancy rate (CPR) after IVF or intracytoplasmic sperm injection (ICSI) procedures. We reviewed 1017 cycles in a total of 975 patients. The …

Dissociation Of Automatic And Strategic Lexical-Semantics: Functional Magnetic Resonance Imaging Evidence For Differing Roles Of Multiple Frontotemporal Regions, Brian T. Gold, David A. Balota, Sara J. Jones, David K. Powell, Charles D. Smith, Anders H. Andersen

Neuroscience Faculty Publications

Behavioral research has demonstrated three major components of the lexical-semantic processing system: automatic activation of semantic representations, strategic retrieval of semantic representations, and inhibition of competitors. However, these component processes are inherently conflated in explicit lexical-semantic decision tasks typically used in functional magnetic resonance imaging (fMRI) research. Here, we combine the logic of behavioral priming studies and the neurophysiological phenomenon of fMRI priming to dissociate the neural bases of automatic and strategic lexical-semantic processes across a series of three studies. A single lexical decision task was used in all studies, with stimulus onset asynchrony or linguistic relationship between prime and …
