Infectious disease expert warns of spread of Rocky Mountain spotted fever

...apidly, causing inflammation of the blood vessels, shock and the build-up of fluid inside the lungs and brain. The precise origins of Rocky Mountain spotted fever are not known, but the disease is only known to occur in North and South America. ...

Environmental lessons from tsunami as world's coastal population doubles

...lthy ecosystems are much more likely to absorb the shock and provide protection from a coastal disaster than man-made structures such as sea walls or artificial reefs. Globally 23 per cent of the world's population (1.2 billion people) live within 100 km of the coast and this figure is likely to increase ...

Fundamental discovery -- Bone fracture

...an bone." He described the discovery of "molecular shock absorbers" providing a kind of self-healing glue holding biological mineralized structures together when studying the abalone shell six years ago. "It's truly remarkable to find the same fundamental mechanisms operating in bone," said Morse. He note...

Discovery Promises Simpler Therapy for Sickle Cell Disease

...sorders, including diabetes, heart attacks, septic shock and sickle cell disease. In the current study, the researchers found that hemoglobin in the red cells of patients with sickle cell disease fails to process nitric oxide properly. As a result, they reported, the membranes of sickle red blood cells ar...

Scientists solve structure of key protein in innate immune response

...utical companies have tried to develop anti-septic shock agents for a long time without clear success," explains Dr. Lee. "Since LPS is an important inducer of septic shock, blocking LPS receptors such as CD14 are among the most important targets. Our structure shows the shape of the LPS binding pocket of ...
