Defining the Critical Hurdles in Cancer Immunotherapy
(BioMed Central, 2011)Scientific discoveries that provide strong evidence of antitumor effects in preclinical models often encounter significant delays before being tested in patients with cancer. While some of these delays have a scientific ... -
Defining the functional states of Th17 cells
(F1000Research, 2015)The molecular mechanisms governing T helper (Th) cell differentiation and function have revealed a complex network of transcriptional and protein regulators. Cytokines not only initiate the differentiation of CD4 Th cells ... -
Defining the Human C2H2 Zinc Finger Degrome Targeted by Thalidomide Analogs Through CRBN
(American Association for the Advancement of Science (AAAS), 2018-11-02)The small molecules thalidomide, lenalidomide, and pomalidomide induce the ubiquitination and proteasomal degradation of the transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) by recruiting a Cys2-His2 (C2H2) zinc ... -
Defining the Range of Cellular Components, Including Internal Antigens, That Can Serve as Targets of Graft Rejection
(Hindawi Publishing Corporation, 1992)The mechanisms underlying rejection of grafted neural tissue are still being defined. Mechanisms relevant to genetically engineered cells are of current interest. To date, attention has focused on major histocompatibility ... -
Defining the role of common variation in the genomic and biological architecture of adult human height
(2014)Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explain one-fifth of heritability for adult height. By testing different numbers of variants in independent ... -
Defining the Role of the MHC in Autoimmunity: A Review and Pooled Analysis
(Public Library of Science, 2008)The major histocompatibility complex (MHC) is one of the most extensively studied regions in the human genome because of the association of variants at this locus with autoimmune, infectious, and inflammatory diseases. ... -
Defining the Value of Future Research to Identify the Preferred Treatment of Meniscal Tear in the Presence of Knee Osteoarthritis
(Public Library of Science, 2015)Background: Arthroscopic partial meniscectomy (APM) is extensively used to relieve pain in patients with symptomatic meniscal tear (MT) and knee osteoarthritis (OA). Recent studies have failed to show the superiority of ... -
Deformability of Tumor Cells versus Blood Cells
(Nature Publishing Group, 2015)The potential for circulating tumor cells (CTCs) to elucidate the process of cancer metastasis and inform clinical decision-making has made their isolation of great importance. However, CTCs are rare in the blood, and ... -
Deformable image registration between pathological images and MR image via an optical macro image
(2016)Computed tomography (CT) and magnetic resonance (MR) imaging have been widely used for visualizing the inside of the human body. However, in many cases, pathological diagnosis is conducted through a biopsy or resection of ... -
Deformable organisms for automatic medical image analysis
(Elsevier BV, 2002)We introduce a new approach to medical image analysis that combines deformable model methodologies with concepts from the field of artificial life. In particular, we propose ‘deformable organisms’, autonomous agents whose ... -
Degenerate in Vitro Genetic Selection Reveals Mutations That Diminish Alfalfa Mosaic Virus RNA Replication without Affecting Coat Protein Binding
(American Society for Microbiology, 2004)The alfalfa mosaic virus (AMV) RNAs are infectious only in the presence of the viral coat protein; however, the mechanisms describing coat protein's role during replication are disputed. We reasoned that mechanistic details ... -
Degeneration and Regeneration of Subbasal Corneal Nerves after Infectious Keratitis
(Elsevier BV, 2015)Purpose To investigate the longitudinal alterations of subbasal corneal nerves in patients with infectious keratitis (IK) during acute phase, cessation of treatment and recovery phase by in vivo confocal microscopy ... -
Degos disease – malignant atrophic papulosis or cutaneointestinal lethal syndrome: rarity of the disease
(Dove Medical Press, 2015)Background: Degos disease is a very rare syndrome with a rare type of multisystem vasculopathy of unknown cause that affects the skin, gastrointestinal tract, and central nervous system. Other organs such as the kidneys, ... -
Degradation of HK2 by chaperone-mediated autophagy promotes metabolic catastrophe and cell death
(The Rockefeller University Press, 2015)Hexokinase II (HK2), a key enzyme involved in glucose metabolism, is regulated by growth factor signaling and is required for initiation and maintenance of tumors. Here we show that metabolic stress triggered by perturbation ... -
Degradation of the Peroxisome Proliferator-activated Receptor γ Is Linked to Ligand-dependent Activation
(American Society for Biochemistry and Molecular Biology, 2000) -
Degree of corticospinal tract damage correlates with motor function after stroke
(BlackWell Publishing Ltd, 2014)Objectives: Direct injury to the corticospinal tract (CST) is a major factor defining motor impairment after stroke. Diffusion tensor imaging (DTI) tractography allows definition of the CST. We sought to determine whether ... -
Deinstitutionalization of the Chronically Mentally Ill
(Massachusetts Medical Society, 1981-08-06)Deinstitutionalization of the mentally ill has become the predominant public mental-health policy in most states. This policy has been supported by a curious political marriage of liberals, who decry the custodial-level ... -
Delay Discrimination and Reversal Eyeblink Classical Conditioning in Abstinent Chronic Alcoholics
(American Psychological Association (APA), 2008-03)Evidence has shown that alcoholism leads to volume reductions in brain regions critical for associative learning using the eyeblink classical conditioning paradigm (EBCC). Evidence indicates that cerebellar shrinkage causes ... -
Delay of transfer from the intensive care unit: a prospective observational study of incidence, causes, and financial impact
(BioMed Central, 2013)Introduction: A paucity of literature exists regarding delays in transfer out of the intensive care unit. We sought to analyze the incidence, causes, and costs of delayed transfer from a surgical intensive care unit (SICU). ... -
Delayed Endovascular Coil Extrusion following Internal Carotid Artery Embolization
(Georg Thieme Verlag KG, 2014)Internal carotid artery injury is a rare and devastating complication of endoscopic sinus and skull base surgery that has an associated mortality rate of 15%. This case describes a patient who developed massive epistaxis ...
