Crossing the species line

A recent article in Developmental and Comparative Immunology reveals that plants possess elements of specificity and responsiveness to disease-causing agents, similar to animal immunity. The study suggests that the plant immune surveillance genes diversify at a rate stimulated by pathogen presence, shedding new light on plant immunity.

The HLA-DRB1 gene and premature death in rheumatoid arthritis

Researchers identified the HLA-DRB1 gene as a predictor of premature death from cardiovascular disease in inflammatory arthritis patients. The study found that having two copies of the shared epitope allele increased the risk of death from all causes and cardiovascular disease, particularly among current smokers.

Drug based on MGH discovery may significantly improve treatment of dangerous blood disorder

A clinical trial shows that romiplostim significantly improved platelet levels in patients with chronic immune thrombocytopenic purpura (ITP), a hematologic disorder that can cause uncontrolled bleeding. The novel drug duplicates the action of a natural hormone discovered by MGH investigator, offering low toxicity and high response rates.

They were right after all

Researchers Aaron C. Smith and Robert M. Williams successfully reproduced the Rabe-Kindler protocol for synthesizing quinine, a key step in its 'formal' total synthesis. They found that using aluminum powder as a reducing agent was crucial to achieving high yields of quinine.
