摘要:
A method of generating astrocytes is disclosed, the method comprising up-regulating miR-101 and down-regulating miR-138 using an agent which hybridizes to the miRNA in mesenchymal stem cells (MSCs). Isolated cell populations and uses thereof are also disclosed.

Technology disclosed herein provides a reduced transition between the edge of a rigid vascular dilator and the distal edge of the accompanying introducer sheath. Disclosed dilators can be segmented into two or more primarily longitudinally extending parts, can have rigid circumferential or semi-circumferential leading shoulders to minimize the transition between the dilator and the sheath edge, and can contain internal recesses to allow sequential retraction of segments once the introducer sheath is delivered to a target chamber. With this technology, vascular introducer sheaths can be introduced percutaneously into a broad range of diseased target vessels and chambers with reduced damage to the wall of the vessel or chamber, and with reduced damage to the distal end of the introducer sheath.
摘要:
A device and method for determining intravascular pressure and irregular needle placement in a hemodialysis procedure include analyzing means for automatically deriving venous access pressure (VAP) at a location of venous needle insertion into the patient and determining a ratio of VAP to mean arterial pressure, where the analyzing means determines multiple VAP values over multiple time periods and determines multiple ratios, one for each VAP value. Detecting means compare each ratio to a predetermined standard ratio derived from a moving average of prior VAP ratios, where the detecting means detects irregular needle placement when elevation of the ratio above the standard ratio is indicated.
