A modified procedure in aortic arch replacement with no deep hypothermic circulatory arrest.

Deep hypothermia or circulation arrest is widely used during total aortic arch replacement. However, conventional procedures have high morbidity and mortality. We use the "branch-first" technique combined with clamping the distal aorta, incorporating a stented elephant trunk to avoid deep hypothermia and circulation arrest.

Optical phase conjugation of diffused light with infinite gain by using gated two-color photorefractive crystal LiNbO:Cu:Ce.

Light focusing in multiple scattering circumstances is important in biomedical imaging, manipulation, and therapy. Until now, many traditional photorefractive crystals have been used to generate an optical phase conjugated wavefront in an analogue time-reversed optical focusing technology. However, owing to erasure of a volume hologram during a reading procedure, the optical energy gain can never reach unity, limiting its application in delivering more energy into a target area.

Inducible miR-145 expression by HIF-1a protects cardiomyocytes against apoptosis via regulating SGK1 in simulated myocardial infarction hypoxic microenvironment.

Background: Myocardial infarction (MI) is partly due to myocardial cell damage caused by hypoxia. MicroRNAs (miRNAs) have been proved to be closely related to the development and progression of many cardiovascular diseases. This study investigated the role of miR-145 in cardiomyocytes under hypoxic condition.

Non-invasive three-dimension control of light between turbid layers using a surface quasi-point light source for precorrection.

Manipulating light non-invasively through inhomogeneous media is an attractive goal in many disciplines. Wavefront shaping and optical phase conjugation can focus light to a point. Transmission matrix method can control light on multiple output modes simultaneously.
