Abstract: A drug carrier with a property of crossing the blood-brain barrier comprises an extracellular vesicle with a human leukocyte antigen-G antibody on its surface. This carrier can serve as a pharmaceutical composition for promoting apoptosis of brain tumor cells, inhibiting growth of brain tumor cells, or reducing expression of O6-methylguanine-DNA methyltransferase (MGMT) in brain tumor cells. These effects contribute to the treatment of glioblastoma multiforme (GBM).

Abstract: A solution for preserving extracellular vesicles/exosomes has a carrier solvent selected from a group consisting of polysorbate 80, sucrose, and polyethylene glycol 3350/4000; and a stabilizer selected from a group consisting of salts, amino acids, and amino acid salts; wherein the pH of the preservation solution ranges from 5 to 7.4.

Abstract: A displaying method for liquid crystal display, which has a light source integrated therein, includes the following steps: inputting a first video signal to the liquid crystal display during a first period of time and controlling the light source by means of modulating a light control signal; and inputting a second video signal to the liquid crystal display during a second period of time and controlling the light source by means of modulating the light control signal, wherein modulation modes of the light control signal are different during the first period of time and the second period of time.

Abstract: An LCD TV comprises a housing, an LCD screen panel disposed on the front side of the housing, a first mirror disposed on the back side of the housing and a projection-based backlight system disposed in a lower cabinet of the housing, wherein the projection-based backlight system provides polarized light for the LCD screen panel through the first mirror. The projection-based backlight system can provide uniformly polarized light and increase polarization efficiency as well as be easily achieved by using low-cost optical components.

Abstract: A test system includes a terminal host and a to-be-tested circuit board. The terminal host generates a trigger signal. The to-be-tested circuit board includes a system chip, a memory and a processor. The system chip receives the trigger signal from the terminal host and generates an interrupt. The memory stores a test program code corresponding to the interrupt. The processor receives the interrupt and executes the test program code corresponding to the interrupt stored in the memory to generate a test result. The system chip transmits the test result to the terminal host.

Abstract: An example of a solution provided here comprises receiving a signal for sending in a side conversation, and in response to the signal for sending, sending a first portion of text, in a side conversation. The first portion of text is new, and the first portion of text is not necessarily revealed to some participants.

Abstract: A hinge device with a locking function includes a first locking element, a first connecting element, a second locking element and a connecting shaft. The first locking element has a first through hole and a first locking portion. The first connecting element has a second through hole. The first connecting element is connected with the first locking element. The second locking element is disposed between the first through hole and the second through hole. The second locking element has a shaft hole and a second locking portion corresponding to the first locking portion. The connecting shaft passes through the first through hole, the shaft hole and the second through hole so as to form the hinge device.

Abstract: A SMD-type LED with high heat dissipation efficiency and high power includes a base with a post arranged and integrated on the center thereof and a slot on top of the post. At least one contact hole is arranged on bottom of the base for connecting with an external heat sink so as to achieve better heat dissipation. The slot is used for accommodating a LED chip that is electrically connected with a circuitry extension device through two electrical contacts. The LED chip is electrically connected with the circuitry extension device directly while it also connects with the base for heat dissipation, thus the structure for electricity conduction is separated from the structure for heat dissipation.
