Abstract: A lighting apparatus includes a light module, a fixing member, a hanging member and an elastic member. The fixing member is fixedly connected to the light module. The fixing member is provided with a side slot. The hanging member is provided with a shaft. The hanging member further includes a hook. The shaft is inserted into the side slot from a side. The shaft is configured to rotate to be in a first state or a second state within the side slot. In the first state the hook is in a vertical position. In the second state the hook is in a horizontal position. The elastic member is fixedly provided on the light module. The elastic member is configured to push upward and press tightly against the shaft to maintain the shaft in the first state or the second state.

Abstract: A lighting apparatus includes an optical component housing, an optical component and a light source. The optical component housing has an optical container and an entrance opening. The entrance opening is disposed on a lateral side of the optical component housing. The optical component housing has a light escape side. The lateral side is at a different plane as the light escape side. The optical component is detachably inserted into the optical container via the entrance opening. a cover manually operable to reveal the entrance opening for inserting the optical component and operable to conceal the entrance opening. a light source. A light is emitted from the light source passing through the optical component and escaped from the light escape side.

Abstract: Disclosed are compositions for targeting 0TUD7A, the compositions having a component sufficient to block and/or reduce OTUD7A-mediated deubiquitination of EWS-FLI1 in a cell. The component can be 7Ai and variants thereof. The compositions can be used to treat Ewing sarcoma (EWS). Methods of using the disclosed compositions are also disclosed, including methods of treating EWS in a subject.
