Targeted H NMR metabolomics and immunological phenotyping of human fresh blood and serum samples discriminate between healthy individuals and inflammatory bowel disease patients treated with anti-TNF.

Inflammatory bowel disease is a multifactorial etiology, associated with environmental factors that can trigger both debut and relapses. A high level of tumor necrosis factor-α in the gut is the main consequence of immune system imbalance. The aim of treatment is to restore gut homeostasis.

Endothelial progenitor cells mobilisation after percutaneous coronary intervention: a pilot study.

Background: The mobilisation process of endothelial progenitor cells (EPC) after stent implantation by percutaneous coronary intervention (PCI) is unclear because the circulating EPC levels are influenced by several pathophysiological factors. The objective was to analyse the kinetics of EPC concentration following elective PCI in patients with stable angina, and its relation with other biomarkers or parameters of cardiovascular function.

Methods: Pilot study in stable angina patients (n = 30) for elective PCI and implantation of bare-metal stent (BMS), drug-eluting stent (DES) or EPC-capturing stent (ECS).

Characterization of the autoimmune response against the nerve tissue S100β in patients with type 1 diabetes.

Type 1 diabetes results from destruction of insulin-producing beta cells in pancreatic islets and is characterized by islet cell autoimmunity. Autoreactivity against non-beta cell-specific antigens has also been reported, including targeting of the calcium-binding protein S100β. In preclinical models, reactivity of this type is a key component of the early development of insulitis.

Proteins involved in platelet signaling are differentially regulated in acute coronary syndrome: a proteomic study.

Background: Platelets play a fundamental role in pathological events underlying acute coronary syndrome (ACS). Because platelets do not have a nucleus, proteomics constitutes an optimal approach to follow platelet molecular events associated with the onset of the acute episode.

Methodology/principal Findings: We performed the first high-resolution two-dimensional gel electrophoresis-based proteome analysis of circulating platelets from patients with non-ST segment elevation ACS (NSTE-ACS).
