Biomonitoring the genetic effects of environmental tobacco smoke exposure in re...

Environmental tobacco smoke (ETS) is recognized as one of the most common indoor pollutants worldwide. Portuguese legislation prohibits smoking in most indoor public spaces. However, in some restaurants/bars smoking is still allowed, representing a potential risk factor for the workers health, particularly for chronic respiratory diseases and cancer onset.The aim of this study was to characterize early signs of...

A possible approach for gel-based proteomic studies in recalcitrant woody plants

Woody plants are particularly difficult to investigate due to high phenolic, resin, and tannin contents and laborious sample preparation. In particular, protein isolation from woody plants for two-dimensional gel electrophoresis (2-DE) is challenging as secondary metabolites negatively interfere with protein extraction and separation. In this study, three protein extraction protocols, using TCA, phenol and etha...

Clinical proteomics stretch goals: EuPA 2012 roundtable report

The field of clinical proteomics is faced with multiple challenges which need to be overcome in order to improve our understanding of human diseases and provide management solutions. Researchers interested in clinical proteomics assembled for a roundtable discussion at the European Association for Proteomics (EuPA) conference held in Glasgow in July 2012, to discuss these challenges and highlight the key areas ...

Chronic Obstructive Pulmonary Disease and Proteomics: A Match for Success?

Chronic obstructive pulmonary disease (COPD) is characterized by chronic airflow limitation that is not fully reversible even under bronchodilators effect, caused by a mixture of small airway disease and parenchymal destruction. COPD is a major cause of morbidity and mortality in adults, and it is now the fourth leading death cause in the world. Cigarette smoking is the main risk factor for COPD but not all smo...

Proteomics in Detection and Monitoring Chronic Lung Diseases: The Human Nasal E...

Asthma and chronic obstructive pulmonary disease (COPD) are major causes of mortality and morbidity worldwide. The current state-of-art diagnosis and management schemes are suboptimal for both diseases as the incidence of asthma has risen by 250% over the last two decades and COPD is estimated to become the third leading cause of death worldwide within the next decade. Additionally, these diseases represent a v...

Plasma and red blood cell proteome in sickle-cell disease

Sickle-cell disease (SCD) is a clinically heterogeneous autosomal recessive monogenic chronic anaemia characterized by recurrent episodes of severe vaso-occlusion, haemolysis and infection. Painful crises are the major SCD clinical manifestation probably due to significant increase in dense red blood cells (RBC) and reduction of their ability to pass through capillaries. Using proteomic strategies, we aim to di...

Optimizing the discovery of predictors of vaso-occlusion in sickle-cell disease...

Painful crises are the major sickle-cell disease (SCD) clinical manifestation probably due to significant increase in dense red blood cells (RBC) and reduction of their ability to pass through capillaries. Using proteomic strategies (see figure below), we aimed to discover novel SCD prognosis biomarkers as early predictors of the transition from steady-state to vaso-occlusive crises thus, allowing a prompt and...
