Provided herein are methods for the treatment of stroke comprising administering to a stroke victim placental stem cells, populations of cells comprising placental stem cells, andor compositions comprising placental stem cells. The sample and hold circuit samples a reference voltage on a bit line of a memory circuit when the sense amplifier is reset and a signal voltage on the same bit line when a signal representing a data bit is present in the bit line. The opening has an insertion region configured to allow the joint, the hydraulic hose and a lower portion of a valve body to be inserted thereinto from above the floor panel, and an arrangement region located in side-by-side relation to the insertion region in a second direction and configured to allow the valve body to be arranged therein while being fixed to the floor panel. For that purpose a winding device for a tube produced in a rolling installation has a bending device for curving the tube so that it can be wound in a spiral shape around a first axis, and a holding frame, wherein the bending device is mounted to the holding frame pivotably about a second axis substantially perpendicular to the first axis. The adjusting assembly includes a plurality of adjusting members.
