Over the past few years, thanks to the unprecedented developments in biology, electronics and human genetics, scientists have developed a range of new devices to protect and improve human health. Advanced medical technology and sophisticated data analysis tools are breaking the traditional limitations of these fields, from hospitals and laboratories into people's daily lives.
The next few short articles provide a brief overview of several of the most promising new technologies, including personalized gene sequencing, artificial vision, cancer, implantable health monitors, and psychosis. Not all of these technologies can succeed, but overall, they show that new technologies will play a more important role not only in disease treatment but also in disease prevention.
Twenty-five years ago, when the Human Genome Project was first launched, it was thought that the project to interpret the "body composition specification" would require hundreds of sequencers, costing $3 billion and 15 years to complete. In 2003, the sequencing of the first set of human genome sequences was successfully completed, but this major scientific achievement is only a rough sketch, and there is still a huge gap to fill.
Time flies, in January 2012, the Las Vegas Consumer Electronics Show, among the dazzling array of gambling machines and flat-panel TVs, the most eye-catching is a genetic sequencer, this white appliance and printer size similar. It can complete a person's whole genome sequencing in a few hours at a price of $1,000. As such affordable gene sequencers go to market, industry observers have predicted that an era of comprehensive genetic testing for ordinary people has arrived.
However, people do not realize that there is no practical medical value for whole-genome sequencing results, whether through doctors or online purchases. The main problem is that the technology is developing too fast and the researchers' ability to interpret the sequencing results has not kept up. For example, each person's genetic sequencing results must be compared to a large number of other people's sequencing results, so that doctors can know which are important disease indicators and which can be ignored. In addition, many diseases are caused by rare mutations that scientists have not identified. So far, the small number of patients who benefit from whole-genome sequencing have mostly rare and obvious genetic mutations. What does this mean for the rest of us? We will wait and see.
Electronic biochemical eyeFinnish Teho suffers from retinitis pigmentosa, a genetic disease that destroys photoreceptors on the retina, and soon after he reaches middle age, he completely loses sight. A few years ago, researchers at the University of Tübingen in Germany implanted a chip into the retina of Teho. This chip replaces photoreceptor cells (ie, rods and cones) that are damaged by the retina. There are 1500 small squares on the chip, each of which contains a photodiode, amplifier and electrodes. When the light hits a photodiode, a weak current is generated, which is amplified by the amplifier and transmitted to the electrode, stimulating the nearby bipolar cells to generate signals, which are then transmitted to the brain through the optic nerve. The more light that illuminates the photodiode, the stronger the current generated.
The chip implanted in the retina opened a window facing the world for Tejo, allowing him to see a range of A4 paper sizes about 1 meter away. Through this window, Tejo can distinguish the basic shape and contour of people and objects, especially when the contrast between light and dark is strong. This dramatically changed the way Tejo interacted with the world. For the first time in 10 years, he was able to see and identify objects such as cutlery and fruit, read letters printed in large prints, and recognize his loved ones.
Since then, researchers have continued to make the implanted chips safer and lighter. The latest chips are wireless and have been ported to the eyes of 10 people so far. The patient can also adjust the brightness and contrast of the field of view.
Author Ferris Jabr Early detection of cancerSome tiny particles may solve a major medical problem. These so-called nanoparticles, which are only a few nanometers in diameter (one nanometer is a billionth of a meter), and 500 particles of this size are arranged together to be as wide as a hair. Scientists are transforming them, hoping to use them to accomplish a variety of tasks: delivering drugs to specific parts of the body; getting clearer images of organs... Now they have one more use, scientists want to use these tiny particles to detect Cancer cells, no matter where they are hidden.
Currently, commonly used imaging tools can detect tumors only when they are large enough to be visible on the scan. With nanoparticles, a single cancer cell can be found in a sample of 10 million normal cells. Nanoparticles can also help doctors distinguish whether a tumor is malignant, progressive, or benign. In theory, doctors can also know the speed of cancer growth and what treatments should be taken.
Scientists also want to create special nanoparticles to perform multiple tasks, such as displaying tumors and even delivering drugs during magnetic resonance imaging, positron emission tomography, and the like. With such nanoparticles, the doctor can confirm whether the drug has reached the position that should be reached and how it works.
Author Katherine Harmon Intelligent implantable deviceBiomedical engineers are developing small, implantable monitoring devices to provide doctors with more information to help them decide how to best treat patients with chronic diseases such as heart disease and diabetes. The implantable device can wirelessly transmit data to the external receiving device from critical parts of the body or blood. Now scientists are developing devices for the two most common diseases:
Heart Attack A monitoring device called "Angel Medical Guardian" is about the size of a pacemaker and can monitor heartbeat. For patients who have had a heart attack not long ago but do not need a pacemaker or defibrillator, the device can monitor abnormal heartbeats, such as sudden acceleration or irregular beats. If the instrument detects that a heart attack is about to occur, it will vibrate and an external pager will sound to alert the patient for help.
Abnormal glucose levels A company in the United States has developed an implantable new glucose sensor. This device continuously monitors the patient's subcutaneous glucose levels to reflect blood glucose concentrations. Therefore, the device gets more accurate and complete information to guide the insulin injection dose and time than the fingertip blood collection monitoring method. Since this sensor is implanted, it does not need to be maintained as always as the currently used in vitro monitoring equipment.
Author Katherine Harmon Blood Test for Mental IllnessSince the 1990s, British researchers have begun collecting brain tissue from the brains of dead schizophrenic patients. They found at least 50 proteins in the sample that were higher or lower than healthy people. In 2006, scientists also found similar biochemical differences in the cerebrospinal fluid and blood of living schizophrenia patients. By detecting the concentration of 51 proteins and other compounds in the blood, schizophrenia patients and healthy people can be distinguished with an accuracy of 80%.
On this basis, the researchers developed a blood test device for schizophrenia that can detect the above 51 marker proteins. Although this device has not been approved by the US Food and Drug Administration, psychiatrists have used it as a reference (only testing in the laboratory does not require FDA approval, but when used in the human body, it is required Meet strict standards).
Psychiatrists recognize these devices to identify schizophrenia and drug-induced mental disorders, and they believe that these devices can help depressed patients accept the fact that they are sick and need treatment.
