Comparison of the Transmembrane Mucins MUC1 and MUC16 in Epithelial Barrier Function
(Public Library of Science, 2014)Membrane-anchored mucins are present in the apical surface glycocalyx of mucosal epithelial cells, each mucosal epithelium having at least two of the mucins. The mucins have been ascribed barrier functions, but direct ... -
Comparison of Therapeutic Effects between Pulsed and Continuous Wave 810-nm Wavelength Laser Irradiation for Traumatic Brain Injury in Mice
(Public Library of Science, 2011)Background: and Objective: Transcranial low-level laser therapy (LLLT) using near-infrared light can efficiently penetrate through the scalp and skull and could allow non-invasive treatment for traumatic brain injury (TBI). ... -
A Comparison of Three Electrophysiological Methods for the Assessment of Disease Status in a Mild Spinal Muscular Atrophy Mouse Model
(Public Library of Science, 2014)Objectives: There is a need for better, noninvasive quantitative biomarkers for assessing the rate of progression and possible response to therapy in spinal muscular atrophy (SMA). In this study, we compared three ... -
A Comparison of Tier 1 and Tier 3 Medical Homes Under Oklahoma Medicaid Program
(2018-05-15)Introduction: The patient-centered medical home (PCMH) is a team-based model of care that seeks to improve quality of care and control costs. The Oklahoma Health Care Authority (OHCA) directs Oklahoma’s Medicaid program ... -
Comparison of Time-Domain OCT and Fundus Photographic Assessments of Retinal Thickening in Eyes with Diabetic Macular Edema
(Association for Research in Vision and Ophthalmology (ARVO), 2008)Purpose: To explore the correlation between optical coherence tomography (OCT) and stereoscopic fundus photographs (FP) for the assessment of retinal thickening (RT) in diabetic macular edema (DME) within a clinical trial. ... -
Comparison of Tissue Architectural Changes between Radiofrequency Ablation and Cryospray Ablation in Barrett's Esophagus Using Endoscopic Three-Dimensional Optical Coherence Tomography
(Hindawi Publishing Corporation, 2012)Two main nonsurgical endoscopic approaches for ablating dysplastic and early cancer lesions in the esophagus have gained popularity, namely, radiofrequency ablation (RFA) and cryospray ablation (CSA). We report a uniquely ... -
Comparison of Two Fixation Methods in Treating Displaced Pediatric Tibial Eminence Fractures at Boston Childrens Hospital
(2015-06-08)Introduction: Tibial eminence fractures (TEF) occur most often in children, and disrupt the bony attachment of the anterior cruciate ligament (ACL) to the tibia. Displaced TEF are managed surgically with reduction and ... -
A Comparison of Two Measures of HIV Diversity in Multi-Assay Algorithms for HIV Incidence Estimation
(Public Library of Science, 2014)Background: Multi-assay algorithms (MAAs) can be used to estimate HIV incidence in cross-sectional surveys. We compared the performance of two MAAs that use HIV diversity as one of four biomarkers for analysis of HIV ... -
Comparison of Two Questionnaires for Dry Eye Symptom Assessment
(Elsevier BV, 2015)Purpose The aim of this study was to compare patient reported symptoms of dry eye disease (DED) as assessed by the Ocular Surface Disease Index (OSDI©), a 12-item symptom frequency-based questionnaire, and the Symptom ... -
Comparison of VIM and STN DBS for Parkinsonian Resting and Postural/Action Tremor
(Columbia University Libraries/Information Services, 2015)Background: Resting tremor is common in Parkinson’s disease (PD), but up to 47% of PD patients have action tremor, which is sometimes resistant to medications. Deep brain stimulation (DBS) of the ventral intermediate nucleus ... -
A comparison of visual and quantitative methods to identify interstitial lung abnormalities
(BioMed Central, 2015)Background: Evidence suggests that individuals with interstitial lung abnormalities (ILA) on a chest computed tomogram (CT) may have an increased risk to develop a clinically significant interstitial lung disease (ILD). ... -
Comparison of Weight-Loss Diets with Different Compositions of Fat, Protein, and Carbohydrates
(New England Journal of Medicine (NEJM/MMS), 2009)BACKGROUND: The possible advantage for weight loss of a diet that emphasizes protein, fat, or carbohydrates has not been established, and there are few studies that extend beyond 1 year. METHODS: We randomly assigned ... -
Comparisons of Subthreshold Versus Full Posttraumatic Stress Disorder Distinguished by Subjective Functional Impairment Among Train Drivers: A Population-Based Nationwide Study in South Korea
(Korean Neuropsychiatric Association, 2017)Objective: Subthreshold posttraumatic stress disorder (SPTSD), a condition that meets the full symptomatic criteria of posttraumatic stress disorder (PTSD) without subjective functional impairment, has yet to be fully ... -
Comparisons of the M1 Genome Segments and Encoded μ2 Proteins of Different Reovirus Isolates
(BioMed Central, 2004)Background: The reovirus M1 genome segment encodes the μ2 protein, a structurally minor component of the viral core, which has been identified as a transcriptase cofactor, nucleoside and RNA triphosphatase, and microtubule-binding ... -

A Compendium of Preparation and Application of Stem Cells in Parkinson's Disease: Current Status and Future Prospects
(Frontiers Media S.A., 2016)Parkinson's Disease (PD) is a progressively neurodegenerative disorder, implicitly characterized by a stepwise loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc) and explicitly marked by ... -
The compensatory dynamic of inter-hemispheric interactions in visuospatial attention revealed using rTMS and fMRI
(Frontiers Media S.A., 2014)A balance of mutual tonic inhibition between bi-hemispheric posterior parietal cortices is believed to play an important role in bilateral visual attention. However, experimental support for this notion has been mainly ... -
Compensatory neural activity distinguishes different patterns of normal cognitive aging
(Elsevier BV, 2008)Most cognitive neuroscientific research exploring the nature of age-associated compensatory mechanisms has compared old adults (high vs. average performers) to young adults (not split by performance), leaving ambiguous ... -
