[A case of cerebral fat embolism after artificial bone replacement operation for femoral head fracture].

A 83 years old woman was slipped and injured with right femoral neck fracture. After three days from the fracture, she underwent an artificial head bone replacement operation. Immediately after surgery, she complained of chest discomfort, nausea and dyspnea.

A novel prolyl hydroxylase inhibitor protects against cell death after hypoxia.

Hypoxia-inducible factor 1 (HIF-1) is regulated by the oxygen-dependent hydroxylation of proline residues by prolyl hydroxylases (PHDs). We recently developed a novel PHD inhibitor, TM6008, that suppresses the activity of PHDs, inducing continuous HIF-1α activation. In this study, we investigated how TM6008 affects cell survival after hypoxic conditions capable of inducing HIF-1α expression and how TM6008 regulates PHDs and genes downstream of HIF-1α.
