The authors also offer recommendations for treating common injuries caused by bomb blasts, such as brain, lung, and orthopaedic injuries.
Patients with rheumatoid arthritis (RA) are at a higher risk of developing coronary artery disease (CAD), with more advanced atherosclerosis and increased cardiovascular death. The underlying RA disease process, particularly elevated CD4+CD28- T cells, contributes to this increased risk.
Researchers challenge traditional model of mRNA translation with discovery of EF-G's binding to GDP and its role as a GTP exchange factor. The ribosome plays a dual role in guanine-nucleotide exchange and GTPase-activation, leading to partial translocation of the mRNA.

The study proposes a new therapeutic window for potent anti-inflammatory therapies during the first few months of clinically apparent disease.
A study of 316 internet websites found that most government and health advice sites incorrectly state the risks of smokeless tobacco as comparable to cigarettes. This misinformation may encourage smokers to stick with a much more hazardous product, despite available harm reduction options like switching to smokeless tobacco.
