Rescue workers tend to the injured at the site of a train derailment in Lian county in northern Taiwan on Sunday, Oct 21, 2018. Passengers were killed and injured on Sunday when one of Taiwan's newer, faster trains derailed on a curve along a popular weekend route, officials said. [Photo/Agencies] BEIJING - Mainland authorities on Monday mourned victims who died in a passenger train derailment in Taiwan Sunday afternoon and sent condolences to their families and the injured. The mainland has paid close attention to the accident, said officials from the State Council's Taiwan Affairs Office and the Association for Relations Across the Taiwan Straits. At least 18 people died and 187 were injured, and two female passengers from the mainland were among the injured, according to the island's railway authority. The Puyuma Express No. 6432 bound for Taitung from Shulin Station with 366 passengers on board derailed at 4:50 p.m. at Xinma Station, Yilan County. All eight cars of the express train derailed, with three of them overturned. The cause of the derailment is still under investigation. The accident, the worst of Taiwan railways in more than three decades, happened on a popular line along the island's east coast. Train services were partially resumed Monday morning. bracelet maker rubbersilicone bracelet manufacturersilicone wristbands onlinemake custom bracelets onlinesilicone wristbands no minimum
NANJING - Chinese scientists have developed a "heart-on-a-chip" device to mimic the beat and contraction of cardiac muscle cells in vitro, which could replace non-human animal models for drug screening."Organ-on-a-chip" research mainly involves designing an inch-long silicone device that houses a network of organ cells, which can effectively model human organs and show results for drug tests.A research team led by Zhao Yuanjin from the state key laboratory of bioelectronics at China's Southeast University has successfully added a structural color hydrogel into a heart-on-a-chip and predicted its clinical values. Their findings were published in the journal Science Robotics in March.The research was inspired by the biological properties of chameleons. Once the color hydrogel is injected into the chip, it shows color changes according to the contraction of cardiac muscle cells.When related medication is adopted for some specific heart diseases, the conditions of the cardiac muscle cells can be monitored through the color-changing hydrogel, said Zhao."This device focuses on building new platforms for the testing and development of new drugs for safety and efficacy. It will not only replace human and non-human animal models for drug screening, but also meet the medical needs of individual patients in the future," Zhao said.
