Cancer Detection By Jellyfish

Hey friends, today i am  going to take you  into the sea and  to look how beautiful the sea creatures are. How amazingly they are living in the sea. But have we ever asked yourselves about how they fight to live their lives, how they survive?How they themselves immuned to disorders, such as cancer? However, now the scientists are going to, in our modern technological life  to try to  find out something different that no-one imagined or thought. I am now going to discuss with you about one of the sea creatures from which the scientists are trying to get something to treat the cancer or to detect the cancer cells. And the most amazing news is, we are almost in the border line of the success.
I am going to discuss about  the beautiful sea creature we know by the name of Jellyfish, isn’t it so beautiful, colorful creation of the sea.

Now our creative, innovative, breakthrough and informative document is that Jellyfish is now inspiring us and our scientists  a way to detect cancer, microbes and viruses. In this research a device is invented which could help quickly and sensitively detect life-threatening diseases and capture dangerous cells for analysis so that doctors can devise the best therapies to fight them.
From this topic I can share with you that sometimes I say : “Nature has overcome the most challenging barriers ….. Evolution really is the best problem-solver, and there is so much we can learn from nature."
I think we all know about DNA but who does not know clearly - DNA is the molecule that holds the blueprints of life. Sequences of DNA known as aptamers also show a remarkable ability to bind onto very specific targets.
To test this device, the researchers generated long DNA strands with aptamers that would bind onto a protein found abundantly on the surfaces of human cancer cells. The strands are up to hundreds of microns long — in comparison, the average human hair is about 100 microns wide. The length of these strands gives them more area to snag onto target proteins and their associated cells than other methods that employ antibodies or shorter DNA strands.
In experiments, blood samples containing leukemia cells were flowed past the device. These long DNA tentacles efficiently captured up to about 80 percent of these cells, about six times more than methods relying on antibodies or shorter DNA strands.
The chip which have developed is highly sensitive, and from just a tiny amount of blood, the chip can detect and capture the small population of cancer cells responsible for cancer  relapse.
In hunting for blood-based cancers, the device might also find cancer cells that have broken away from tumors and are traveling through the bloodstream. Roaming cancers known as metastases are the leading cause of deaths from cancer, but these wandering cells are very rare in the bloodstream, with just a few to several thousand per milliliter of a patient's blood.
This device has the potential to catch these cells before they may seed a new tumor in a distant organ. The researchers say that they could speed up  the system  fast enough for practical use in the clinic.
Even the researchers say that if a patient had a rapid test they  could tell  where these cells can seed a metastasis, that would help to monitor the progression of therapy and progression of the disease.
One of the greatest challenges in the treatment of cancer patients is to know which drug to prescribe. But we can say that, "By isolating circulating tumor cells before and after the first round of chemotherapy is given, we can determine the biology behind why certain cells are resistant to chemotherapy. We can also use the isolated cells to screen drugs for personalized treatments that could boost effectiveness and hopefully prevent cancer relapse."

So, dear friends, i hope you really enjoyed knowing about the above innovation by the researchers towards saving lives and i am really hoping that you all snap out some spare time in the day of tomorrow to join us in our blog spot, to get amazed with an incredible breakthrough achieved in our medical science. Till then stay healthy, be passionate and keep blogging.
