A team of scientists from ETH Zurich and other institutions has developed a novel perfusion machine capable of preserving human livers outside the body for up to one week and restoring damaged livers to a healthy state. Globally, organ shortages persist due to insufficient supply meeting clinical demand, and current techniques struggle to extend organ viability beyond a single day.This new perfusion machine has successfully kept livers viable outside the body for seven days. Scientists explain that the device mimics normal liver function by delivering blood and oxygen, managing blood sugar levels and red blood cell counts. Crucially, it operates fully autonomously without requiring constant monitoring.
The liver is critically important to our bodies, ranking among our most vital organs. Liver dysfunction plunges the body into severe crisis—fatty liver disease being a common example. Currently, fatty liver disease ranks as China's second most prevalent liver disorder, with surveys indicating its incidence continues to rise.The exact causes of fatty liver disease remain unclear, though experts suggest potential links to environmental factors, genetics, or abnormal fat metabolism.
As the body's primary metabolic organ, liver dysfunction can lead to excessive fat accumulation within hepatocytes, resulting in fatty liver disease.Do not underestimate the harm fatty liver disease can cause to the human body. If you develop fatty liver disease, you may experience symptoms such as fatigue, loss of appetite, abdominal distension, or weight loss. In severe cases, it can lead to cirrhosis. Therefore, preventing fatty liver disease is also very important. How to Prevent Fatty Liver Disease First, avoid eating high-calorie foods.
Many people struggle with calorie control in their daily lives, frequently consuming high-calorie foods—a major contributor to weight gain. It's important to understand that when the body cannot burn off all the calories consumed, the excess is converted into fat and stored. As fat accumulates, it gradually leads to fatty liver disease.
Second, reduce high-sugar foods.
Our daily activities rely heavily on glucose. However, excessive sugar intake stimulates fat synthesis in the body, increasing fat content and raising the risk of developing fatty liver disease. Therefore, in daily life, we must be mindful to limit consumption of sweets, chocolate, and other sugary foods. Additionally, fruits with high sugar content should also be eaten in moderation.
Third, quit smoking.
Alcohol is a significant contributor to fatty liver disease. The culture of drinking at banquets is widespread, with many people frequently drinking to excess. While a small portion of alcohol is metabolized in the stomach, over 90% is broken down by the liver. Consequently, long-term alcohol consumption can damage the liver, potentially leading to fatty liver disease.
