Unlocking H5N1 virus replication: an interview with Martin Blackledge

We were able to show that one small domain of the polymerase, the part that is essential for entry of a piece of the polymerase into the cell nucleus, changes its conformation to allow it to interact with the transporter protein than takes it into the nucleus.

"Neoehrlichiosis" Internationally Diagnosed And Successfully Treated In Patients Without Immunodeficiency For The First Time

The intercellular bacteria "Candidatus Neoehrlichia", as e.g. Borrelia, can be transferred by ticks. Approx. 4.2 % of indigenous ticks are infected with this rarely explored bacterium which, until today, has been exclusively identified as pathogenic bacterium in patients with an impairment of the immune system, such as in case of leukaemia, rheumatism or after organ transplantation.

Over-expression of heme oxygenase-1 enzyme protects the heart from doxorubicin damage

Life-threatening heart damage is an adverse side effect of the cancer drug doxorubicin, damage that also limits the use of newer chemotherapeutic agents such as trastuzumab and imatinib. The ability to protect the heart from these side effects would benefit patients, including cancer survivors who are at risk of developing heart damage years later, and it also could allow safer use of these drugs at higher doses.

Mayo Clinic researchers discover new bacterial species that triggers Lyme disease in people

Mayo Clinic researchers, in collaboration with the Centers for Disease Control and Prevention and health officials from Minnesota, North Dakota and Wisconsin, have discovered a new bacterial species that causes Lyme disease in people. The new species has been provisionally named Borrelia mayonii. Prior to this finding, the only species believed to cause Lyme disease in North America was Borrelia burgdorferi.

Researchers successfully test new method for rapid diagnosis of Ebola in Guinea

An international team of researchers, including Ahmed Abd El Wahed, scientist at the University of Göttingen and the German Primate Center, has tested a new method for rapid diagnosis of Ebola in a field trial in Guinea. The test procedure was carried out using a portable suitcase laboratory. The mobile suitcase lab is operated with solar power and enables simple on-site diagnostics in remote areas without the need of an equipped laboratory.

Certain drugs could be used to treat gastric cancers with particular pattern of mutations

Gastric cancer, otherwise known as stomach cancer, does not respond well to existing treatments and it is currently the third leading cause of cancer death in the world (after lung and liver cancer). Researchers have discovered that certain drugs, currently used to treat breast, ovarian and pancreatic cancers, could also be used to treat certain gastric cancers with a particular pattern of mutations (genomic molecular fingerprint).

Brown University researchers describe new method to test HIV mutations

Tests that can distinguish whether HIV-positive people are infected with a drug-resistant strain or a non-resistant strain allow patients to get the most effective treatment as quickly as possible. In the November edition of the Journal of Molecular Diagnostics, a team of Brown University researchers describes a new method that works faster and more sensitively in lab testing than the current standard technologies.
