Abstract: The present disclosure provides a method for treating liver cirrhosis by using a composition including mesenchymal stem cells, extracellular vesicles produced by the mesenchymal stem cells, and growth factors. The composition of the present disclosure achieves the effect of treating liver cirrhosis through various efficacy experiments.

Abstract: An integrated circuit (IC) structure includes a semiconductor substrate, a first gate line, a second gate line, and a first auxiliary gate portion. The semiconductor substrate comprises a semiconductor fin. The semiconductor fin extends substantially along a first direction. The first gate line and the second gate line extend substantially along a second direction different form the first direction from a top view. The first auxiliary gate portion connects the first gate line to the second gate line from the top view.

Abstract: A multimedia device includes a body, a first electronic module and a second electronic module. The first electronic module and the second electronic module are pivotally connected onto the body, respectively. The first electronic module and the second electronic module are configured to rotate relatively to the body and capture or display a multimedia information, respectively.

Abstract: A power saving method and a handheld electronic device using the same are provided. The method includes the following steps. A trigger signal is received. An user interface is displayed in a touch display panel unit of the handheld electronic device, wherein the user interface includes at least one control item and the at least one control item respectively corresponds to at least one working mode of the handheld electronic device. An operating signal corresponding to one of the at least one control item is received from the touch display panel unit. The working mode of the handheld electronic device is switched according to the operating signal and a working frequency of the handheld electronic device is adjusted according to the working mode.

Abstract: A paint ball gun includes a gun barrel mounted on a gun handle. The gun barrel is formed with parallel propelling and recuperator chambers for respectively receiving a propelling member and a recuperating unit. A connecting rod interconnects the propelling member and a recuperator member such that the propelling member is movable together with the recuperator member. A manually operable pull unit is mounted in the propelling chamber posteriorly of the propelling member, and includes a pull rod with a front rod portion formed with an elongated slot and a rear rod portion which extends out of the propelling chamber. The connecting rod extends through and is slidable along the elongated slot. The pull unit further has a biasing spring for biasing the pull rod forward.
