Health-recovering bed

A health-recovering bed which is suitable for the patient who is not convenient to move and is long-term bed. The bed surface is divided into a central bed surface and both sides edging shelves and is with trisection appearance. The outboard of the both sides edging shelves are pin connected with the bedstead body by connecting bars, and the both ends of the central bed surface head are connected by a cylinder. It can achieve the shift operation of the both sides edging shelves by controlling the stretching of the cylinder. A revolution axis assembled an eccentric wheel board is installed at the bottom of the central bed surface, and the lateral bars disposed on the central bed surface is controlled by the revolution axis to do the arc fluctuation action, so it can make the patient turn over and do the massage sport on the bed.

Cell-based dna sensors and methods of using same

Cell-based DNA sensors, compositions comprising the cell-based DNA sensors, and methods of detecting DNA and cells. The cell-based DNA sensors include competent cells that include genetic circuits. Each genetic circuit includes homology arms separated by an interstitial region that comprises at least one element of a reporter switch and/or a kill switch. The compositions include one or more cell-based DNA sensors. The cell-based DNA sensors can be used to detect DNA and cells by the genetic circuits undergoing homologous recombination with target regions of target DNA to activate or deactivate the reporter switch and/or kill switch.
