A new way of testing e-nose: 'nose' that smells diseases, with this electronic nose, diseases like liver, lung and colon cancer will be able to detect.
Scientists are developing new types of tests to identify diseases. An electronic nose or e-nose is the best example of this type of modern test. Diseases like liver, lung, and colon cancer can be detected through electronic noses.
To check for diseases, this nose has to be applied like a mask on your nose and the disease will be detected within a few seconds.UK Biotech company Oulstone Medical, who prepared it, says that work is also being done to detect Covid with the help of an electronic nose (e-nose).
According to the research, usually, the patient does not feel comfortable while giving blood, urine, and stool samples, but the new test will prove to be very easy for the patients and will also take very least time.
Now the question is how Electronic Nose Works?
This e-nose detects the disease by detecting the smell of disease coming from the patient's breath. Scientists say that when humans exhale, there are more than 3500 Volatile Organic Compounds (VOCs) in it. It consists of extremely small gas particles and microscopic droplets. E-nose detects chemicals present in volatile organic compounds and thus detects diseases.
It took 51 years to make the device. The idea of creating it came to scientists in 1970 itself, but it took decades to convert this idea into a sensitive device, programming to recognize volatile organic compounds, and creating sensors. Its trial is going on in many countries around the world. The results, especially in the UK, have been impressive.
Experts say, in the next five years, the test done through e-nose will become like a routine test. Continuous work is being done on this. Scientists say it is being tried that the device can also tell which medicine will be better for the patient according to the disease.
Using the same technology for cancer screening-
Through this technique, clinical trials related to breathing are going on in many countries around the world. It also includes trials related to cancer. The goal of the trial is to detect cancer early. The trial is being conducted on 4000 patients in UK hospitals in collaboration with Cambridge University and the NHS Foundation.
The first human trial of breast cancer vaccine started in America claims; This will prevent the most dangerous type of triple-negative breast cancer. To prevent breast cancer, the Cleveland Clinic of America has started the trial of the first phase of its vaccine. With the help of this trial, triple-negative breast cancer, the most dangerous type of cancer, can be controlled.
The Cleveland Clinic is working closely with vaccine company Anixa Bioscience after receiving approval for a vaccine trial from the US Food and Drug Administration. Why this trial is special and what it means, let us discuss in detail-
The new vaccine has the potential to prevent breast cancer, says Vincent Tuofi, immunologist and vaccine developer at Cleveland Clinic's Learner Research Institute. Of all the cases of breast cancer, 12 to 15 are triple-negative breast cancer patients. This is the most serious type of breast cancer. Its cases are seen more in African and American women. So it needs to be controlled.
Before the trial, this vaccine was given to patients aged 18 to 24 years suffering from this cancer. Tumors were completely eradicated in these patients. Monitoring is being done to understand the risk of re-tumor in them. In the first phase of the trial, this vaccine will be given to the initial patients suffering from triple-negative breast cancer. To fight cancer, how much immune response is visible in their body, maybe justified with this trial.
Patients involved in the first phase trial will be given three doses of the vaccine. The effect and side effects of the vaccine will be monitored for 2 weeks. This entire trial will be completed by September 2022. The pre-clinical trial of the vaccine was done on rats. During the trial, it was revealed that the vaccine activated the immune system and was successful in preventing breast cancer tumors.
Research published in the journal Nature Medicines says that this vaccine is effective on other tumors. If the first human trial is successful, then this vaccine can make big changes in the medical world.
