The plant toxin ricin is one of the most poisonous naturally occurring proteins, making it an extremely dangerous bioweapon. Ricin attacks have made the headlines a number of times over the years, including the spectacular "umbrella murder" in London in the 1970s, or more recently the ricin letters addressed to

Multifunctional Nano Sized Drug Carriers Based on Reactive Polypept(o)ides

In cooperation with researchers from the University of Tokyo and Gutenberg Research Awardee Prof. Kazunori Kataoka, Chemists from Mainz have been able to demonstrate that reactive polypept(o)ides constitute ideal building blocks to control morphology and function of carrier systems in a simple but precise manner. Polypept(o)ides (polysarcosine-block-polypeptide copolymers) have emerged

Study Sets New Distance Record for Medical Drone Transport

In a report of the findings, published in the American Journal of Clinical Pathology on Sept. 6, the investigators say the achievement adds to evidence that unmanned aircraft can be an effective, safe and timely way to quickly transport medical samples from remote sites to laboratories. "We expect that in many cases, drone

Producing Malaria Treatment at Large Scales

The first-choice treatment for malaria is artemisinin -- which is used in Chinese medicine to treat fever and inflammation as well as malaria. Before 2001, health care officials around the world administered the drug as a single compound, but this allowed malaria parasites to become drug-resistant. Scientists and medical professionals

Immune Cells Help Fat Deal With Environmental Challenges

The number of obese people as well as those suffering from type 2 diabetes is increasing worldwide. Both disorders are associated with metabolic changes including amplified inflammatory responses in adipose tissue. "Previous studies have indicated that immunosuppressive regulatory T-cells -- or Tregs for short -- play an important role in
