L-Theanine Down-Regulates the JAK/STAT3 Pathway to Attenuate the Proliferation and Migration of Vascular Smooth Muscle Cells Induced by Angiotensin II.

L-Theanine, a green tea amino acid derivative, has cardiovascular qualities. The focus of the current evaluation was to examine the suppression of L-theanine on cultured vascular smooth muscle cell (VSMC) proliferation and migration that is prompted by angiotensin II (Ang II). The VSMCs were treated with non-cytotoxic concentrations of L-theanine and then stimulated with Ang II.

[The development of the multifunctional automatic rotating bed with process-monitoring].

We have developed a new rotating bed for the old and the paralised people. This rotating bed is composed of two bed heads at front and at end, bed boards, guardrails, an electric motor, a reducer, an induction locator and a set of electronic controls. With the preestablished program, the angle between the left/right bed board and the middle board is changed by rotating the left/right board around the rotation axis, and the gravity direction between the human body and the ground is changed by the rotation of the middle board as a whole, so that the middle bed board and the left and right ones will act respectively as supporters of weight of the person who is lying on his back or on his side.
