A 53-year-old man, who performed a 44-minute dive to a depth of 21 meters, felt severe abdominal pain with dyspnea after surfacing. An ultrasound study showed a marked snowstorm pattern in the portal vein of the liver and right ventricle, and whole body computed tomography revealed multiple gas bubbles in the right ventricle, inferior vena cava, portal, mesenteric and femoral vein. He was thus diagnosed to have decompression sickness and was therefore transported to another hospital to undergo hyperbaric oxygen therapy.

We report the discovery of a potent and selective FPR2 agonist and its evaluation in a mouse heart failure model. A simple linear urea with moderate agonist activity served as the starting point for optimization.

Unlike other members of the MAPK family, ERK5 contains a large C-terminal domain with transcriptional activation capability in addition to an N-terminal canonical kinase domain. Genetic deletion of ERK5 is embryonic lethal, and tissue-restricted deletions have profound effects on erythroid development, cardiac function, and neurogenesis. In addition, depletion of ERK5 is antiinflammatory and antitumorigenic.

MicroRNAs play an important role in the development and progression of various diseases, such as idiopathic pulmonary fibrosis (IPF). Although the accumulation of aberrant fibroblasts resistant to apoptosis is a hallmark in IPF lungs, the mechanism regulating apoptosis susceptibility is not fully understood. Here, we investigated the role of miR-29, which is the most downregulated microRNA in IPF lungs and is also known as a regulator of extracellular matrix (ECM), in the mechanism of apoptosis resistance.
