The present invention provides a composition for modulating MARCH-I, MHC II and / or CD86 in the cells of an ex vivo organ, that is to say an organ taken from a donor for subsequent transplantation in a recipient. In one embodiment, the composition comprises one or more organ preservation solutions in combination with an Hsp. In another embodiment, the composition of the invention comprises Hsp70 and / or one or more synthetic Hsp70-derived peptides. The composition of the invention provides preservation while at the same time reducing rejection of an organ, thus offering many advantages and solving various relevant technical problems: not only preserving the useful life of the organ but also initiating a process in the organ which inhibits acute rejection; lengthening the useful life of the organ in vivo; having local immunomodulating effects in the recipient; having an indirect impact on the quality of life of the transplant recipient by necessitating fewer immunossuppressive medications; inducing the activity of regulatory T cells (which are acknowledged to be immunosuppressors), reducing the expression of MHC molecules in the graft, reducing alloreactive expression in the recipient's lymph nodes, and lengthening the survival of the graft in the recipient.

A driving device of an electric discharge lamp includes: a discharge lamp lighting unit which supplies power to the electric discharge lamp while alternately switching polarity of voltage applied between two electrodes of the electric discharge lamp to lighting the electric discharge lamp; and an anode duty ratio modulating unit which sets at least a first retention period and a second retention period having an anode duty ratio different from that of the first retention period and provided after the first retention period to modulate the anode duty ratios, assuming that each of the retention periods is a period for retaining an anode duty ratio as ratio of an anode period in which one of the electrodes operates as anode at a constant value in one cycle of the polarity switching, wherein the anode duty ratio modulating unit has a first modulation mode for operating the electric discharge lamp in steady condition and a second modulation mode for providing larger change of the anode duty ratio between the first retention period and the second retention period than change of the first modulation mode.

A test system and a corresponding method for testing the seal of a glove which is installed in a port of an isolator, including a test disc which can be connected in a hermetically sealed fashion to the port. The glove and test disc define a sealed glove volume which can be placed under excess pressure. The test disc has a pressure-measuring device with a microprocessor and a memory for recording and storing a pressure profile in the glove volume and a data interface. The glove and port have identification elements which are read by a reading device of the test disc and information concerning the pressure profile along with the identities of the glove and port are transmitted wirelessly to an evaluation unit which estimates and records a residual period of use of the glove. A plurality of gloves in ports can be tested simultaneously.

The invention relates to a battledore handle and a manufacturing method thereof, belongs to the athletic sports appliance industry, and in particular relates to a battledore handle of a novel structure and a manufacturing method of the battledore handle. The battledore handle comprises a front cone and a carbon fiber handle, wherein a center hole is formed in the middle of the front cone; and grooves are designed in the upper and lower surfaces of the front cone. The manufacturing method comprises the following steps: filling cut PU foam materials in the two sides and grooves of the front cone, coating carbon fiber composite material prepreg cloth coated with resins on the exterior, inserting a front cone positioning pin into the center hole of the front cone so as to complete front cone preforming; and coiling the carbon fiber handle by using the cut carbon fiber prepreg cloth, and coating the front cone and the carbon fiber handle layer by layer by using the carbon fiber prepreg cloth, so that the front cone and the carbon fiber handle are tightly connected together, and an integrated battledore handle is formed. According to the application of the manufactured battledore handle disclosed by the invention on the battledore, the shock absorption performance of the front cone part of the battledore handle is increased, the strength of the battledore handle is stable, the precision is high, the stability of the battledore frame is effectively improved after ball hitting, the shock reduction performance of the battledore is improved, and sports injuries are reduced.

The invention discloses a locking device of a grounding knife switch of a switch cabinet. The locking device of the grounding knife switch of the switch cabinet comprises a locking device body (5), wherein the locking device body (5) is provided with a three-phase electromagnetic generating device (1); one side of the three-phase electromagnetic generating device (1) is connected with a power supply (2), and the other end of the three-phase electromagnetic generating device (1) is linked with a grounding knife switch (3); the three-phase electromagnetic generating device (1) is linked with a baffle plate (4) of an operating hole in the grounding knife switch (3); a connecting rod (5) of the three-phase electromagnetic generating device (1) drives the baffle plate (4) to perform moving limit; when an electric cable is electrified, the three-phase electromagnetic generating device (1) drives the baffle plate (4) to move to close the operating hole in the grounding knife switch (3), and the grounding knife switch (3) stops operating; and when the electric cable is not electrified, the three-phase electromagnetic generating device (1) drives the baffle plate (4) to move to close the operating hole in the grounding knife switch (3), and the grounding knife switch (3) begins to operate.

A mouse pen and a photoelectric control switch thereof are provided, the photoelectric control switch includes a control rod in a shell moving between on-position and off-position, an optical coupling sensor comprising a light emitter and light receiver disposed on an extension line of the control rod, and an elastic element for resetting the control rod.
