Scientists from Singapore Immunology Network (SigN) in cooperation with Newcastle University have discovered a new class of white blood cells which activate the response of immunological system to alien antigens. It has a chance to be a breakthrough in creation of vaccines against many dangerous diseases such as hospital acquired pneumonia, hepatitis B or tumours.
European Journal of Immunology has published the results of research conducted by professor Chang Kim from Purdue University in West Lafayette. In his works he proved that properly modified blood cells may be used in treatment of autoimmune diseases, for example rheumatoid arthritis or Crohn’s disease.
According to the recent study carried out by researchers from Queen Mary, University of London, published in the American Heart Association journal Hypertension, a cup of beetroot juice a day can help lower blood pressure in patients with hypertension. Read full text »
Since the introduction of recombinant human erythropoietin (rhEPO) to clinical practice it seemed that the problem of anaemia in patients with chronic kidney disease has been brought under control. Further years have produced modifications of particles of rhEPO and led to the synthesis of new medicines – erythropoiesis stimulating agents. These drugs are characterized by longer half-life and the stability of action. However, the results of recent clinical trials carry dangerous conclusions. Despite the improvement of morphological parameters, the reduction of mortality in these patients was not observed.
Human serum albumin (HSA) plays a very important role in the human body and is used in many clinical cases. Because of the problems associated with its extraction researchers have been working on new methods of creating it. Proceedings of the National Academy of Sciences published the latest results of research on transgenic rice seeds from which HSA was isolated. Read full text »

A new blood test may predict patients at risk of an imminent heart attack. Researchers have discovered mutated circulating endothelial cells (CECs) that are released into the bloodstream days before the formation of a clot. A blood test may be used to identify this particular cell type up to 2 weeks before the heart attack is likely to occur. Continue reading
Malignant neoplasms change the rheological properties of the blood, leading to a higher risk of thrombosis. Treatment of a cancer also affects the haemostasis. Recent studies carried out in the Deutsches Krebsforschungszentrum (Heidelberg) showed that not only the cancer is causing the thrombosis, but the prothrombotic trend may increase the risk of malignant neoplasm occurrence.
