All patients tested for influenza A(H1N1)2009 by Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) and procalcitonin between June 2009 and January 2010 were analyzed. Read More

    Validation of a protein panel for the noninvasive detection of recurrent non-muscle invasive bladder cancer.
    Biomarkers 2017 Jan 19:1-8. Epub 2017 Jan 19.
    a Health and Environment Department, Bioresources Unit, AIT Austrian Institute of Technology GmbH , Tulln , Austria.
    Context: About 50-70% of patients with non-muscle invasive bladder cancer (NMIBC) experience relapse of disease.

    Objective: To establish a panel of protein biomarkers incorporated in a multiplexed microarray (BCa chip) and a classifier for diagnosing recurrent NMIBC.

    Materials And Methods: Urine samples from 45 patients were tested. Read More

    Beta-2-glycoprotein-1 and alpha-1-antitrypsin as urinary markers of renal cancer in von Hippel-Lindau patients.

    e Department of Urology , Azienda Ospedaliera Città della Salute e Della Scienza di Torino - Molinette , Turin , Italy.
    Context: Von Hippel-Lindau disease (VHLD) is a rare inherited neoplastic syndrome. Among all the VHLD-associated tumors, clear cell renal cell carcinoma (ccRCC) is the major cause of death.

    Objective: The aim of this paper is the discovery of new non-invasive biomarker for the monitoring of VHLD patients. Read More

    MGMT hypomethylation is associated with DNA damage in workers exposed to low-dose benzene.
    Biomarkers 2017 Jul 12;22(5):470-475. Epub 2017 Jan 12.
    a Guangzhou Key Laboratory of Environmental Pollution and Health Risk Assessment, Department of Toxicology, School of Public Health , Sun Yat-sen University , Guangzhou , China.
    Objective: This study aims to assess the effects of low-dose benzene on DNA damage and O(6)-methylguanine-DNA methyltransferase (MGMT) methylation in occupational workers.

    Materials And Methods: We recruited 96 nonsmoking male petrochemical industry workers exposed to low-dose benzene and 100 matched control workers. Urinary S-phenylmercapturic acid (SPMA) and S-benzylmercapturic acid (SBMA) were measured for indicating internal exposure of benzene and toluene. Read More

    Investigation of transrenal KRAS mutation in late stage NSCLC patients correlates to disease progression.
    Biomarkers 2016 Dec 21:1-7. Epub 2016 Dec 21.
    a Department of Respiratory Medicine , Wuhan No. 6 Hospital, Affiliated Hospital to Jianghan University , Wuhan , People's Republic of China.
    Purpose: Using transrenal DNA to detect KRAS mutations in non-small cell lung cancer (NSCLC), the study addressed the clinical impact for longitudinal monitoring and prognostic value for disease outcome.

    Methods: Digital droplet PCR was used to detect the mutant DNA. A total of 200 NSCLC patients were recruited with varying molecular profiles. Read More
