Differences Among Cardiologists in Rates of Positive Coronary Angiograms
(John Wiley and Sons Inc., 2015)Background: Understanding the sources of variation for high‐cost services has the potential to improve both patient outcomes and value in health care delivery. Nationally, the overall diagnostic yield of coronary angiography ... -
Differences in Clinicopathology of Early Gastric Carcinoma between Proximal and Distal Location in 438 Chinese Patients
(Nature Publishing Group, 2015)Early gastric carcinoma (EGC) in Chinese patients remains poorly understood and endoscopic therapy has not been well established. Here, we compared endoscopic and clinicopathologic features between early proximal gastric ... -
Differences in cortical response to acupressure and electroacupuncture stimuli
(Springer Nature, 2011)Background FMRI studies focus on sub-cortical effects of acupuncture stimuli. The purpose of this study was to assess changes in primary somatosensory (S1) activity over the course of different types of acupuncture ... -
Differences in Heart Rate Variability Associated with Long-Term Exposure to NO2
(National Institute of Environmental Health Sciences, 2008)Background: Heart rate variability (HRV), a measure of cardiac autonomic tone, has been associated with cardiovascular morbidity and mortality. Short-term studies have shown that subjects exposed to higher traffic-associated ... -
Differences in HER2 over-expression between proximal and distal gastric cancers in the Chinese population
(Baishideng Publishing Group, 2013)AIM: To investigate HER2 expression and its correlation with clinicopathological variables between proximal and distal gastric cancers (GC) in the Chinese population.METHODS: Immunostaining of HER2 was performed and scored ... -
Differences in Platelet Function in Patients With Acute Myeloid Leukemia and Myelodysplasia Compared to Equally Thrombocytopenic Patients With Immune Thrombocytopenia
(Wiley-Blackwell, 2011)BACKGROUND: Severe thrombocytopenia is a major risk factor for hemorrhage, but platelet function and bleeding risk at low platelet counts are poorly understood, because of the limitations of platelet function testing at ... -
Differences in Redox Regulatory Systems in Human Lung and Liver Tumors Suggest Different Avenues for Therapy
(MDPI, 2015)A common characteristic of many cancer cells is that they suffer from oxidative stress. They, therefore, require effective redox regulatory systems to combat the higher levels of reactive oxygen species that accompany ... -
Differences in Self-Reported Health in the Osteoarthritis Initiative (OAI) and Third National Health and Nutrition Examination Survey (NHANES-III)
(Public Library of Science (PLoS), 2011-02-28)Objective: To assess self-reported health status (SRHS) in two cohorts of participants with radiographic knee osteoarthritis (OA) and examine the extent that differences in SRHS are due to study design. Method: We used ... -
Differences in sex distribution, anatomic location and MR imaging appearance of pediatric compared to adult chordomas
(BioMed Central, 2016)Background: Chordomas are rare malignancies that primarily affect adults, but also rarely affect pediatric patients. We compared the imaging appearance, demographic and anatomic distributions of adult and pediatric chordomas ... -
Differences in the right inferior longitudinal fasciculus but no general disruption of white matter tracts in children with autism spectrum disorder
(National Academy of Sciences, 2014)One of the most widely cited features of the neural phenotype of autism is reduced "integrity" of long-range white matter tracts, a claim based primarily on diffusion imaging studies. However, many prior studies have small ... -
Differences in the Selection Bottleneck between Modes of Sexual Transmission Influence the Genetic Composition of the HIV-1 Founder Virus
(Public Library of Science, 2016)Due to the stringent population bottleneck that occurs during sexual HIV-1 transmission, systemic infection is typically established by a limited number of founder viruses. Elucidation of the precise forces influencing the ... -
Differences in white matter reflect atypical developmental trajectory in autism: A Tract-based Spatial Statistics study☆
(Elsevier, 2012)Autism is a neurodevelopmental disorder in which white matter (WM) maturation is affected. We assessed WM integrity in 16 adolescents and 14 adults with high-functioning autism spectrum disorder (ASD) and in matched ... -
Different behavioral effects of neurotoxic dorsal hippocampal lesions placed under either isoflurane or propofol anesthesia
(Wiley Subscription Services, Inc., A Wiley Company, 2007)Anesthetic protocols for behavioral neuroscience experiments are evolving as new anesthetics are developed and surgical procedures are refined to improve animal welfare. We tested whether neurotoxic dorsal hippocampal ... -
Different Cortical Dynamics in Face and Body Perception: An MEG study
(Public Library of Science, 2013)Evidence from functional neuroimaging indicates that visual perception of human faces and bodies is carried out by distributed networks of face and body-sensitive areas in the occipito-temporal cortex. However, the dynamics ... -
Different effects of anesthetic isoflurane on caspase-3 activation and cytosol cytochrome c levels between mice neural progenitor cells and neurons
(Frontiers Media S.A., 2014)Commonly used anesthetic isoflurane has been reported to promote Alzheimer’s disease (AD) neuropathogenesis by inducing caspase-3 activation. However, the up-stream mechanisms of isoflurane’s effects remain largely to be ... -
Different Facets of Copy Number Changes: Permanent, Transient, and Adaptive
(American Society for Microbiology, 2016)Chromosomal copy number changes are frequently associated with harmful consequences and are thought of as an underlying mechanism for the development of diseases. However, changes in copy number are observed during development ... -
Different MMSE Score Is Associated with Postoperative Delirium in Young-Old and Old-Old Adults
(Public Library of Science, 2015)Background: Postoperative delirium is one of the most common postoperative complications in geriatric patients. Mini-mental state examination (MMSE) assesses cognitive function in patients and is associated with postoperative ... -
Different Pattern of Immunoglobulin Gene Usage by HIV-1 Compared to Non-HIV-1 Antibodies Derived from the Same Infected Subject
(Public Library of Science, 2012)A biased usage of immunoglobulin (Ig) genes is observed in human anti-HIV-1 monoclonal antibodies (mAbs) resulting probably from compensation to reduced usage of the VH3 family genes, while the other alternative suggests ... -
Different Roles of Mast Cells in Obesity and Diabetes: Lessons from Experimental Animals and Humans
(Frontiers Research Foundation, 2012)Mast cells (MCs) play an important role in allergic hyperresponsiveness and in defending microorganism infections. Recent studies of experimental animals and humans have suggested that MCs participate in obesity and diabetes. ... -
