Which Sample Type Is Better For Xpert Mtb/Rif To Diagnose Adult And Pediatric Pulmonary Tuberculosis?, Mengyuan Lyu, Jian Zhou, Yuhui Cheng, Weelic Chong, Kang Wu, Teng Fang, Tianbo Fu, Binwu Ying

Department of Medicine Faculty Papers

OBJECTIVE: This review aimed to identify proper respiratory-related sample types for adult and pediatric pulmonary tuberculosis (PTB), respectively, by comparing performance of Xpert MTB/RIF when using bronchoalveolar lavage (BAL), induced sputum (IS), expectorated sputum (ES), nasopharyngeal aspirates (NPAs), and gastric aspiration (GA) as sample.

METHODS: Articles were searched in Web of Science, PubMed, and Ovid from inception up to 29 June 2020. Pooled sensitivity and specificity were calculated, each with a 95% confidence interval (CI). Quality assessment and heterogeneity evaluation across included studies were performed.

RESULTS: A total of 50 articles were included. The respective sensitivity and specificity were 87% …

Phosphorylation Of Cyclophilin D At Serine 191 Regulates Mitochondrial Permeability Transition Pore Opening And Cell Death After Ischemia-Reperfusion, Stephen Hurst, Fabrice Gonnot, Maya Dia, Claire Crola Da Silva, Ludovic Gomez, Shey-Shing Sheu

The mitochondrial permeability transition pore (mPTP) plays a critical role in the pathogenesis of cardiovascular diseases, including ischemia/reperfusion injury. Although the pore structure is still unresolved, the mechanism through which cyclophilin D (CypD) regulates mPTP opening is the subject of intensive studies. While post-translational modifications of CypD have been shown to modulate pore opening, specific phosphorylation sites of CypD have not yet been identified. We hypothesized here that phosphorylation of CypD on a serine residue controls mPTP opening and subsequent cell death at reperfusion. We combined in silico analysis with in vitro and genetic manipulations to determine potential CypD phosphorylation …

A Novel Signature Based On Microvascular Invasion Predicts The Recurrence Of Hcc., Binbin Du, Fang Wang, Beers Jarad, Zhihui Wang, Yanzhou Zhang

Department of Medicine Faculty Papers

BACKGROUND AND OBJECTIVES: In hepatocellular carcinoma (HCC) patients, microvascular invasion (MVI) is associated with worse outcomes regardless of treatment. No single reliable preoperative factor exists to predict MVI. The aim of the work described here was to develop a new MVI- based mRNA biomarker to differentiate between high and low risk patients.

METHODS: Using The Cancer Genome Atlas (TCGA) database, we collected data from 315 HCC patients, including mRNA expression and complete clinical data. We generated a seven-mRNA signature to predict patient outcomes. The mRNA signature was validated using the GSE36376 cohort. Finally, we tested the formula in our own …

Differences In Brain Morphometry Associated With Creative Performance In High- And Average-Creative Achievers., Evangelia G Chrysikou, Christopher Wertz, David B Yaden, Scott Barry Kaufman, Donna Bacon, Nancy Wintering, Rex E Jung, Andrew B. Newberg, Md

Nearly everyone has the ability for creative thought. Yet, certain individuals create works that propel their fields, challenge paradigms, and advance the world. What are the neurobiological factors that might underlie such prominent creative achievement? In this study, we focus on morphometric differences in brain structure between high creative achievers from diverse fields of expertise and a 'smart' comparison group of age-, intelligence-, and education-matched average creative achievers. Participants underwent a high-resolution structural brain imaging scan and completed a series of intelligence, creative thinking, personality, and creative achievement measures. We examined whether high and average creative achievers could be distinguished …
