A Bayesian network meta-analysis of PCSK9 inhibitors, statins and ezetimibe with or without statins for cardiovascular outcomes
(European Journal of Preventive Cardiology, 2018-05-01)© 2018, © The European Society of Cardiology 2018. Background: The comparative effects of statins, ezetimibe with or without statins and proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors remain unassessed. ... -
A beta-adrenergic receptor kinase-like enzyme is involved in olfactory signal termination.
(Proc Natl Acad Sci U S A, 1993-02-15)We have previously shown that second-messenger-dependent kinases (cAMP-dependent kinase, protein kinase C) in the olfactory system are essential in terminating second-messenger signaling in response to odorants. We now document ... -
A blood-based host gene expression assay for early detection of respiratory viral infection: an index-cluster prospective cohort study.
(The Lancet. Infectious diseases, 2020-09-24)BACKGROUND:Early and accurate identification of individuals with viral infections is crucial for clinical management and public health interventions. We aimed to assess the ability of transcriptomic biomarkers to identify ... -
A C-terminal motif found in the beta2-adrenergic receptor, P2Y1 receptor and cystic fibrosis transmembrane conductance regulator determines binding to the Na+/H+ exchanger regulatory factor family of PDZ proteins.
(Proc Natl Acad Sci U S A, 1998-07-21)The Na+/H+ exchanger regulatory factor (NHERF) binds to the tail of the beta2-adrenergic receptor and plays a role in adrenergic regulation of Na+/H+ exchange. NHERF contains two PDZ domains, the first of which is required ... -
A constitutively active mutant beta 2-adrenergic receptor is constitutively desensitized and phosphorylated.
(Proc Natl Acad Sci U S A, 1994-03-29)The beta 2-adrenergic receptor (beta 2AR) can be constitutively activated by mutations in the third intracellular loop. Whereas the wild-type receptor exists predominantly in an inactive conformation (R) in the absence of ... -
A crowdsourced analysis to identify ab initio molecular signatures predictive of susceptibility to viral infection.
(Nature communications, 2018-10-24)The response to respiratory viruses varies substantially between individuals, and there are currently no known molecular predictors from the early stages of infection. Here we conduct a community-based analysis to determine ... -
A dual role for ErbB2 signaling in cardiac trabeculation.
(Development, 2010-11)Cardiac trabeculation is a crucial morphogenetic process by which clusters of ventricular cardiomyocytes extrude and expand into the cardiac jelly to form sheet-like projections. Although it has been suggested that cardiac ... -
A flexible statistical model for alignment of label-free proteomics data--incorporating ion mobility and product ion information.
(BMC Bioinformatics, 2013-12-16)BACKGROUND: The goal of many proteomics experiments is to determine the abundance of proteins in biological samples, and the variation thereof in various physiological conditions. High-throughput quantitative proteomics, ... -
A functional polymorphism in the 5HTR2C gene associated with stress responses also predicts incident cardiovascular events.
(PLoS One, 2013)Previously we have shown that a functional nonsynonymous single nucleotide polymorphism (rs6318) of the 5HTR2C gene located on the X-chromosome is associated with hypothalamic-pituitary-adrenal axis response to a stress ... -
A Genomic Signature of Influenza Infection Shows Potential for Presymptomatic Detection, Guiding Early Therapy, and Monitoring Clinical Responses.
(Open Forum Infect Dis, 2016-01)Early, presymptomatic intervention with oseltamivir (corresponding to the onset of a published host-based genomic signature of influenza infection) resulted in decreased overall influenza symptoms (aggregate symptom scores ... -
A host gene expression approach for identifying triggers of asthma exacerbations.
(PloS one, 2019-01)RATIONALE:Asthma exacerbations often occur due to infectious triggers, but determining whether infection is present and whether it is bacterial or viral remains clinically challenging. A diagnostic strategy that clarifies ... -
A host transcriptional signature for presymptomatic detection of infection in humans exposed to influenza H1N1 or H3N2.
(PLoS One, 2013)There is great potential for host-based gene expression analysis to impact the early diagnosis of infectious diseases. In particular, the influenza pandemic of 2009 highlighted the challenges and limitations of traditional ... -
A magnificent time with the "magnificent seven" transmembrane spanning receptors.
(Circ Res, 2003-03-07) -
A miRNA Host Response Signature Accurately Discriminates Acute Respiratory Infection Etiologies.
(Frontiers in microbiology, 2018-01)Background: Acute respiratory infections (ARIs) are the leading indication for antibacterial prescriptions despite a viral etiology in the majority of cases. The lack of available diagnostics to discriminate viral and bacterial ... -
A Multifaceted Approach to Pulmonary Hypertension in Adults With Congenital Heart Disease.
(Progress in cardiovascular diseases, 2018-09)Advances in the management of congenital heart disease (CHD) in children have resulted in growing numbers of adults with CHD. Pulmonary arterial hypertension related to CHD (PAH-CHD) is a common complication, affecting up ... -
A Novel Approach to Practice-Based Learning and Improvement Using a Web-Based Audit and Feedback Module.
(Journal of Graduate Medical Education, 2014-09)Systematically engaging residents in large programs in quality improvement (QI) is challenging.To coordinate a shared QI project in a large residency program using an online tool.A web-based QI tool guided residents through ... -
A novel inflammatory biomarker, GlycA, associates with disease activity in rheumatoid arthritis and cardio-metabolic risk in BMI-matched controls.
(Arthritis Res Ther, 2016-04-12)BACKGROUND: RA and CVD both have inflammation as part of the underlying biology. Our objective was to explore the relationships of GlycA, a measure of glycosylated acute phase proteins, with inflammation and cardiometabolic ... -
A practical method of I-131 thyroid cancer therapy dose optimization using estimated effective renal clearance.
(SAGE Open Med Case Rep, 2017)In thyroid cancer patients with renal impairment or other complicating factors, it is important to maximize I-131 therapy efficacy while minimizing bone marrow and lung damage. We developed a web-based calculator based on ... -
A putatively functional polymorphism in the HTR2C gene is associated with depressive symptoms in white females reporting significant life stress.
(PloS one, 2014-01)Psychosocial stress is well known to be positively associated with subsequent depressive symptoms. Cortisol response to stress may be one of a number of biological mechanisms that links psychological stress to depressive ... -
A risk score for in-hospital death in patients admitted with ischemic or hemorrhagic stroke.
(J Am Heart Assoc, 2013-01-28)BACKGROUND: We aimed to derive and validate a single risk score for predicting death from ischemic stroke (IS), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH). METHODS AND RESULTS: Data from 333 865 stroke ...
