10 Biotechnology Breakthroughs that Will Change Medicine

1) Cancer Spit Test

It is a device designed by researchers at the University of California Los Angeles which detects oral cancer from a single drop of saliva. Proteins that are been associated with the cancer cells react with dyes on the sensor, and thereby emitting fluorescent light that can be detected with the help of a microscope. Engineer Chih Ming Ho noted that this principle could be applied to make saliva based diagnostic tests for many diseases.

2) Prosthetic Feedback

There are actually very difficult to monitor. Skin becomes sensitive when it is been stretched ,it can detect even very small changes in its direction and intensity, so Bark is developing a device that stretches an amputee’s skin near the prosthesis in as many ways that provide feedback about the limb’s position and its movements.

3) Smart Contact Lens

Glaucoma which is also the second-leading cause of blindness develops when the pressure builds up inside the eye and eventually damages retinal cells. Contact lenses which are developed at the University of California Davis contain conductive wires that continuously monitor pressure and fluid flow within the eyes of at-risk people. Then the lenses transfers information to a small device worn by the patient; the device wirelessly transmits it to a computer. The continuous data flow will help the doctors to understand the causes of the disease.

4) Speech Restorer

This device is for the people who have lost their ability to talk, a new “phonetic speech engine” provides an audible voice. It is developed in conjunction with Texas Instruments, the Audio uses electrodes to check the neuronal signals traveling from the brain to the vocal cords. During this the Patients imagine slowly sounding out words; then the device wirelessly transmits those impulses to a computer which produces speech.

5) Absorbable Heart Stent

The stents open arteries which have become narrowed or blocked is because of coronary artery disease. This can be medicated by using drug-eluting stents which keeps the artery from narrowing again. The bio-absorbable version is unlike metal stents it does its job and then disappears. After six months, stent begins to dissolve and after two years it’s completely gone, leaving behind a healthy artery.

6) Muscle Stimulator

The usual time it takes for broken bones to heal during this the nearby muscles often atrophy from lack of use. The StimuHeal company solves the problem with the MyoSpare, a battery-operated device which uses electrical stimulators that is actually small enough to be worn underneath casts to exercise muscles and keeping them strong during recovery.

7) Nerve Regenerator

Nerve fibers can’t grow along injured spinal cords since scar tissue gets in their way. A nanogel is been developed which eliminates that impediment. The nanogel is been injected as a liquid which self-assembles into a scaffold of nanofibers. Peptides from the fibers instruct stem cells would normally form scar tissue to produce cells that encourage nerve development. Meanwhile, scaffold supports the growth of new axons up and down the spinal cord.

8) Smart Pill

Proteus Biomedical has engineered sensors that track medication by recording the exact time drugs are ingested. Grain sized microchips emit high frequency electrical currents that are logged by Band Aid like receivers on the skin. The receivers monitor heart rate, respiration and finally wirelessly transmit the data to a computer.

9) Autonomous Wheelchair

An autonomous wheelchair was developed by the MIT researchers that can take people where they ask to go. The chair learns about the environment by listening such as a patient identifies the locations like for example “this is my room” or “we’re in the kitchen” and builds maps using Wi-Fi, which works well indoors. The current model which is now being tested may be equipped with cameras, laser rangefinders and a collision- avoidance system in the upcoming future ahead.

10) Portable Dialysis

Millions of adult in America suffer from diseases of the kidneys, which impair the ability of the organs to remove toxins from the blood. Standard dialysis procedure involves three long sessions at a hospital per week. But an artificial kidney developed by Xcorporeal can clean blood around the clock. The machine is an automated, battery-operated, waterproof , less weight and portable.

Restatistical Report of Human Genome Project

The greatest map of key variations crossways the human genome, and use aimed at hone the fight against innate disease and gaining insight into our species’ odyssey.

The map focuses on so-called copy number variations, or CNVs — segment in the genetic code that may be delete or copied.

Such change, it is thought, can give clues about a variety of diseases and about human being evolution.

humanimmune1

The investigate, unconfined by the British science journal Nature, entailed scanning and compare the genome of 450 people of European, African or East Asian descent.

The results demonstrate that any two genomes be different by more than 1,000 CNVs, or around 0.8 percent of a person’s DNA code. Most of these CNVs are deletions and only a small number are duplication.”The study is more than 10 times as powerful as our first map, available three years ago and much more thorough than any other,”.



The team concern, though, that so far the chart has yet to yield secrets about susceptibility to multifaceted, multi-gene diseases such as heart disease or diabetes.

One is that we have 75 “jumping genes” — regions of the genetic code that can be found in more than one location in some persons. Another is that additional than 250 genes can lose one of the two copies that we have in our chromosomes and yet not impose any obvious ill penalty for health.

In adding, 56 other genes can meld together, potentially form new composite genes.

“The genetic ‘blueprint’ of humans is the human genome,” Mark.“But we are each single as individuals, shaped by variation in both genome and environment. Sympathetic the variation in the middle of human genomes is key to sympathetic the innate differences between each of us in health and disease.”
