Low angle light scattering analysis: a novel quantitative method for functional characterization of human and murine platelet receptors

13-Dec-2011 | Igor Mindukshev; Stepan Gambaryan; Linda Kehrer; Claudia Schuetz; Anna Kobsar; Natalia Rukoyatkina; Viacheslav ..., Clinical Chemistry , 2011

Abstract Background: Determinations of platelet receptor functions are indispensable diagnostic indicators of cardiovascular and hemostatic diseases including hereditary and acquired receptor defects and receptor responses to drugs. However, presently available techniques for assessing platelet ...


Combined effects of coffee consumption and serum γ-glutamyltransferase on serum C-reactive protein in middle-aged and elderly Japanese men and women

16-Jun-2011 | Ngoc Minh Pham; Wang Zhenjie; Makiko Morita; Keizo Ohnaka; Masahiro Adachi; Hisaya Kawate; Ryoichi Takayanagi ..., Clinical Chemistry , 2011

Abstract Background: The association between coffee intake and circulating levels of C-reactive protein (CRP) may be modified by oxidative stress. The authors examined the relation of coffee consumption to serum CRP considering potential interactions of serum γ-glutamyltransferase (GGT) and ...


Review: Genetics of infectious diseases: hidden etiologies and common pathways

27-May-2011 | Marianna Orlova; Tania Di Pietrantonio; Erwin Schurr, Clinical Chemistry , 2011

Abstract Since the completion of the human genome sequence, the study of common genetic polymorphisms in complex human diseases has become a main activity of human genetics. Employing genome-wide association studies, hundreds of modest genetic risk factors have been identified. In infectious ...


Serum APRIL, a potential tumor marker in pancreatic cancer

25-May-2011 | Feng Wang; Lin Chen; Weifeng Ding; Guihua Wang; Yueping Wu; Jingchun Wang; Leilei Luo; Hui Cong; Yueguo Wan ..., Clinical Chemistry , 2011

Abstract Background: A proliferation-inducing ligand (APRIL) is a newly-found member in the tumor necrosis factor (TNF) superfamily. Our previous studies have already confirmed that APRIL is overexpressed in pancreatic cancer tumors, however, it is not expressed or has a weak expression in normal ...


Helicobacter pylori-induced tyrosine phosphorylation of IKKβ contributes to NF-κB activation

23-May-2011 | Cornelia Rieke; Anja Papendieck; Olga Sokolova; Michael Naumann, Biological Chemistry, 2011

Abstract Helicobacter pylori, the etiological agent of several human gastric diseases, induces the transcription factor nuclear factor-κB (NF-κB) in colonized epithelial cells leading to the release of proinflammatory mediators. Activation of NF-κB involves the IκB kinase (IKK)-complex composed ...


Recent insights into regulation of transcription by RNA polymerase III and the cellular functions of its transcripts

23-May-2011 | Tatyana V. Nikitina; Lyudmila I. Tischenko; Wolfgang A. Schulz, Biological Chemistry, 2011

Abstract The products of transcription by the multisubunit enzyme RNA polymerase III (Pol III), such as 5S rRNA, tRNAs, U6 snRNA, are important for cell growth, proliferation and differentiation. The known range of the Pol III transcriptome has expanded over recent years, and novel functions of ...


In vitro conversion and seeded fibrillization of posttranslationally modified prion protein

23-May-2011 | Jan Stöhr; Kerstin Elfrink; Nicole Weinmann; Holger Wille; Dieter Willbold; Eva Birkmann; Detlev Riesner, Biological Chemistry, 2011

Abstract The conversion of the cellular isoform of the prion protein (PrPC) into the pathologic isoform (PrPSc) is the key event in prion diseases. To study the conversion process, an in vitro system based on varying the concentration of low amounts of sodium dodecyl sulfate (SDS) has been ...


Effect of sample collection, temperature and time of storage on β-galactosidase and total hexosaminidase activities in dried blood collected on filter paper

17-May-2011 | Cristina D. de Castilhos; Jamila Mezzalira; Mariana P.S. Goldim; Frederico G. Werlang; Janice C. Coelho, Clinical Chemistry , 2011

Abstract Background: Dried blood spots (DBS) on filter paper is a valuable sampling technique in clinical chemistry, but the stability of enzymes used in the diagnosis of lysosomal storage diseases (LSDs) needs to be evaluated. Methods: In a first experiment, blood from 20 subjects was collected ...

Review: Diagnostic, prognostic and therapeutic relevance of B-type natriuretic hormone and related peptides in children with congenital heart diseases

12-Apr-2011 | Massimiliano Cantinotti; Stefania Giovannini; Bruno Murzi; Aldo Clerico, Clinical Chemistry , 2011

Abstract The aim of this article is to review the diagnostic and prognostic relevance of measurement of brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in pediatric patients with congenital cardiac diseases (CHD). A computerized literature search in the ...
