Google DeepMind has beaten the human Go championship with AlphaGo, and now it is beginning to enter the medical field. According to the Guardian, DeepMind and NHS (National Health Service System) have once again collaborated with Moorfields Eye Hospital to develop a machine learning system for identifying visual diseases. Through an eye scan, the system recognizes early symptoms of visual illness and achieves the goal of preventing visual illness in advance.
This is the second collaboration between DeepMind and NHS. Prior to this, DeepMind worked with the Royal Free Hospital in North London to monitor the patient's kidney function with a smartphone. DeepMind co-founder Mustafa Suleyman said the collaboration was the first pure medical research conducted by the company. At the same time, this is the first time the company has applied machine learning to medical projects.

At the heart of the study is the sharing of 1 million eye scans. DeepMind researchers will train a machine learning system to better identify early symptoms of visual illness.
"This study is very important, especially the diagnosis of diabetic retinopathy. If you have diabetes, then your chances of becoming blind will increase by 25 times. If we can detect this condition and start treatment as soon as possible, then, 98% of severe visual loss can be avoided," Suleyman said.
The collaboration between Moorfields and DeepMind is due to Pearse Keane, a consulting ophthalmologist at the hospital. On DeepMind's official website, Pearse Keane explored how to do an analysis of the eye scan, and then he contacted Suleyman to start the collaborative project.
Carnitine, or trans. carnitine, is an amino acid, a quaternary ammonium cationic complex, which can be biosynthesized from both lysine and methionine and is involved in the metabolism of fat into energy in the body. Carnitine has two stereoisomerism: L-Carnitine, which is biologically active, and D-carnitine, which is non-biologically active. L-carnitine (L-carnitine) is an amino acid widely distributed in the liver, especially in myocardium and skeletal muscle. Most of the carnitine required by the body comes from meat and dairy products in the diet. [1]
Carnitine is an amino acid widely distributed in the liver, especially in cardiac muscle and skeletal muscle. Most of the carnitine components required by the body come from meat and dairy products in the diet. In addition, the body itself can synthesize part of methionine as raw material, and the body needs Vitamin C, iron, B6 and niacin as auxiliary factors of various enzymes in the reaction when biosynthesizing carnitine. L-carnitine is widely present in the body, especially in mitochondria. The concentration of L-carnitine was highest in the adrenal gland, followed by the heart, bone, muscle, adipose tissue and liver. Free L-carnitine is excreted in the urine. Plant-based foods contain less l-carnitine (in some cases none), as well as less lysine and methionine, the two essential amino acids that make carnitine. The l-carnitine content in animal food is high, especially in liver. Foods rich in L-carnitine include yeast, milk, liver, meat and other animal foods. Humans and most animals can also meet their physiological needs through synthesis within their bodies. L-carnitine is not deficient under normal conditions.
