Shortness of breath can be measured – pulmonary exercise testing

Shortness of breath can be measured – pulmonary exercise testing When a patient often suffers from shortness of breath, general practitioners, internists and even pneumologists are not always able to find the cause directly – since many factors control how patients themselves perceive shortness of breath. Pulmonary exercise testing and blood gas analyses refine diagnosis and provide more clues about the causes.Shortness of breath can be measured – pulmonary exercise testing - Read more

T cell receptor ensures Treg functionality

Photo: Researcher Christoph Vahl in his laboratory [09/01/2015] T cells play an important role in the immune system, destroying pathogens and controlling the body's immune responses. Every T cell has its own special T cell receptor (TCR) on its surface that only recognizes one specific substance. To protect the body, the majority of these autoreactive cells are destroyed before they fully mature.T cell receptor ensures Treg functionality - Read more

Complications from blood transfusions more common than previously reported

Photo: Hanging, empty blood bags [16/12/2014] Two studies shed new light on the prevalence of transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), the number one and two leading causes of blood transfusion-related deaths in the United States.Complications from blood transfusions more common than previously reported - Read more

Taming the inflammatory response in kidney dialysis

Graphic: Structure of a complex molecule [15/12/2014] Frequent kidney dialysis is essential for the approximately 350,000 end-stage renal disease (ESRD) patients in the United States. But it can also cause systemic inflammation, leading to complications such as cardiovascular disease and anemia, and patients who rely on the therapy have a five-year survival rate of only 35 percent.Taming the inflammatory response in kidney dialysis - Read more

Nanotechnology against malaria parasites

Graphic: Erythrocytes in a bloodvessel [11/12/2014] Malaria parasites invade human red blood cells, they then disrupt them and infect others. Researchers at the University of Basel and the Swiss Tropical and Public Health Institute have now developed so-called nanomimics of host cell membranes that trick the parasites.Nanotechnology against malaria parasites - Read more

Membrane reduces scarring in damaged blood vessels

Graphic: Blood vessel with a narrowing, blood flow [01/12/2014] When blood vessels are damaged through surgery, it can trigger an endless cycle of scarring and repair. Now, a new surgical membrane delivers the healing action of vitamin A.Membrane reduces scarring in damaged blood vessels - Read more

Obesity fuels silent heart damage

Graphic: Display of BOLD signal [26/11/2014] BOLD signals in functional magnetic resonance imaging do not always reflect what nerve cells are doing: Researchers use functional magnetic resonance imaging (fMRI) to identify which areas of the brain are active during specific tasks.Dopamine leaves its mark in brain scans - Read more

Bio-inspired bleeding control

Photo: synthetic platelets [17/11/2014] Stanching the free flow of blood from an injury remains a holy grail of clinical medicine. Controlling blood flow is a primary concern and first line of defense for patients and medical staff in many situations, from traumatic injury to illness to surgery. If control is not established within the first few minutes of a hemorrhage, further treatment and healing are impossible.Bio-inspired bleeding control - Read more
