Publication number: 20250082787Abstract: The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.Type: ApplicationFiled: November 21, 2024Publication date: March 13, 2025Applicant: National Cancer CenterInventors: Yong Doo CHOI, Seon Sook LEE, Hyun Jin KIM, Dae Kyung SOHN, Seok Ki KIM, Young Woo KIM, Keun Won RYU, Hong Man YOON

Publication number: 20100050882Abstract: A water-cooled barbecue system which prevents overheating of the interior thereof and a grill and also prevents leakage of water from the appliance when the operation thereof is stopped. A burner is within the main body, a grill is disposed on the upper part of the main body, water circulates in the interior of the grill, and a cooling system for cooling water is included in the barbecue system. A bimetal switch interrupts power to a solenoid gas valve at a predetermined temperature. A fan introduces outer air into the main body's interior and the bimetal switch supplies power to the fan when a predetermined temperature is sensed. A thermal sensor is mounted on a liquid pipe through which water flows out from the grill, and a micom receives data from the thermal sensor and outputs a control signal to the cooling system and the solenoid gas valve.Type: ApplicationFiled: November 1, 2007Publication date: March 4, 2010Inventor: Keun-Jin Lee
