For people, it is a wonderful thing to be young forever, but the paradox is that our body is constantly rushing to aging. However, there are always some scientists who hope to help humans fight against the "law of nature" and delay the process.
Two researchers from the University of Washington, Matt Kaeberlein and Daniel Promislow, used a long-lasting drug, rapamycin, to test, but interestingly, the drug was originally used to treat organ transplants. Subsequent rejections, as early as 1999, have passed FDA approval.
This time, the experiment of successfully delaying aging is not applied to the human body, but to dogs. In this experiment, a total of 40 "volunteers" were enrolled. After screening, the researchers excluded 16 patients with heart disease that may affect the results of the experiment, and the remaining 24 entered the formal experiment. These 24 ages Both are over 6 years old and weigh more than 40 pounds (about 18 kilograms).

They take three rapamycin tablets a day, and after 10 weeks, compare the ECG before and after taking the drug. The results showed that the dog's heart function was mostly improved, some remained normal, and even the highest dose of the dog did not show any unpleasant side effects.
This result is undoubtedly surprising. In addition to the enlightenment of human anti-aging drug development, as a "part" in the family, extending the life of the dog can also improve people's quality of life to some extent. At a scientific meeting last month, Kaeberlein said in his speech that they would like to conduct a five-year in-depth study in the future, which may require 450 "volunteers", but unfortunately, they did not have financial support.
The utility model for cleaning the sample cup of a blood cell analyzer relates to a medical cleaning device, which mainly includes a cleaning device, a sample cup tray, a cup tray storage rack, etc. In the sample cup of the sample cup and tray, the inner wall of the sample cup is cleaned, and then ventilated and dried for use. It solves the problem of uncleanness and slow cleaning speed of manual cup washing. This technology has high cleaning degree and fast cleaning speed, which can effectively improve medical personnel Work efficiency, with high promotion and use value.
