Abstract: The present disclosure provides gene expression profiles that are associated with cancer, including certain gene expression profiles that differentiate between cancer that is at a high risk of recurrence. The gene expression profiles can be measured at the nucleic acid or protein level. The gene expression profiles can also be used to identify a subject for cancer treatment. Also provided are kits for use in predicting cancer recurrence and/or prognosing cancer and an array comprising probes for detecting the unique gene expression profiles associated with cancer.

Abstract: A medical device includes a needle coupled with a syringe and is configured to feed a guidewire through the needle and out of a tip of the needle with only one hand and without decoupling the needle from the syringe. A user can feed the guidewire through the device using the same hand holding the device and using the same hand that applies a vacuum in the syringe. The device frees up the user's other hand to control the position of an ultrasonic transducer to continuously visualize all steps of vascular access, including feeding of the guidewire into the blood vessel or other hollow cavity of a patient.

Abstract: The embodiments is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe; and a fixed-wing assembly and a rotor assembly, both replaceably connected to the airframe. The fixed-wing assembly is connected to the airframe to form a vertical take-off and landing fixed-wing unmanned aerial vehicle and the rotor assembly is connected to the airframe to form a multi-rotor unmanned aerial vehicle, thereby implementing an unmanned aerial vehicle that can switch between the vertical take-off and landing fixed-wing unmanned aerial vehicle and the multi-rotor unmanned aerial vehicle.

Abstract: The embodiment is an unmanned aerial vehicle. The unmanned aerial vehicle includes: an airframe, including first mounting portions, where the first mounting portion includes a first mounting body and connecting rods formed on the first mounting body, the connecting rods extending in a pitch axis direction; and a power assembly, including a first assembling body and eccentric wheels mounted on the first assembling body, where the eccentric wheel is rotatable between a first rotation position and a second rotation position of the first assembling body around a rotation axis of the first assembling body, the rotation axis being perpendicular to the pitch axis direction.
