Nano medicine, hope to cure cancer

What is NANO medicine? How is this new treatment principle and treatment? What are the effects and prospects of NANO medicine in treating cancer? These are issues that humanity is concerned about and hoping for.

Recently, the Institute of National Cancer Prevention (Institut national du cancer) of the United States has just confirmed and announced a new medical invention with great promise in treating cancer with the birth of a method. The new medical treatment called Nanomedecine is translated as ' NANO Medicine ' (the French pronunciation "NANO" means ' extremely small '; the ' nano ' prefix is ​​attached to 1 unit) measurement to indicate the size of a billionth: 1/109, for example nanoseconde = 1 / billionth of a second (the author's note).

This medical discovery is the successor of the ideas of Jennifer West and Naomi Hallas, two female scientists in the United States, dating back to 1992, with techniques for making and bringing microcapsules with killer substances. Cancer enters into malignant cells to mark and destroy them directly by Para Prasa and Earls Bergey, two Professors of Buffallow University - New York, USA. Professor S. James Baker of the University of Michigan - USA has " designed " and successfully fabricated the " multidimensional NANO " (nanoparticules polyvalentes) to realize the treatment goals of NANO medicine. So what is NANO medicine?

We can generally define: NANO medicine is a medical industry that uses extremely small particles, capable of bringing pharmaceuticals to infected cells, cancer cells, to destroy They are direct, where the body is sick.

The new treatment method of NANO medicine was published in the Cambridge-Massachusetts - USA Journal of Medicine - Engineering in June 2006, which has been tested, the application has a positive effect, is recognized, allowed and Encouraged to put into use in some countries around the world.

This new treatment starts with injecting a transparent fluid into the body, nothing noticeable; however, in that fluid contains many very small particules, specially made to penetrate biological membranes (membranes biologiques) like blood vessel walls . and are attached to the cells. cancer cells before being absorbed by these cells as nutrients.

These elements are regarded as 'leurres', placing ' luminescent markers ' (mollécules marqueurs fluorescents) on malignant cells (targets) and will destroy them on The journey passes by securing the special medicinal herbs brought along.

' Designed ' by Professor S. James Baker, a researcher at Michigan State University - USA, the 'multivalent NANO particles ' are ready for human clinical trials since 2006. and is currently the 'spearhead' of the medical revolution based on NANO techniques.

These techniques can fundamentally alter the methods of diagnosis and treatment of cancer as well as any other internal diseases. This new treatment method uses multiple-valued NANO particles.

James Baker's technique is based on the use of a high ' branching molecule ', called Dendrimere , roughly translated as ' Branching Cells '. On the cross section of each of these ' Branching Cells', there are more than 100 molecular 'crochets'. Baker has attached these 5 or 6 ' molecular hooks ' to folic acid molecules, an essential vitamin of protein found on the surface of most cells in the body.

These proteins are considered ' receptors ' (récéptes), more so on the surface of cancer cells than on benign cells. James Baker had the idea of ​​attaching the rest of these branched cells some anticancer drugs. Thus, whenever the cancer cells of their proteins absorb folic acid, they absorb the medicinal herbs that will destroy them.

The effectiveness of this new treatment is confirmed by research, experimental work on mice and human bodies, opening up a great prospect in detecting and treating many incurable diseases, especially with cancer.

The researchers also applied NANO medicine to treat a whole series of diseases from rheumatism to severe genetic diseases commonly found in the secretions of the exudate, infecting the pancreas, bronchi, causing chronic digestive and respiratory disorders. However, the treatment against cancer is the main goal of NANO medicine industry.

For breast and ovarian cancer, melanoma ' Kaposi ' melanoma disease, common in HIV-infected patients, viral capsules have the ability to deliver specific medications to approach Directly with these cancer cells and future treatments are highly effective.

The conference summarizing the experiments in June 2006 in the United States, confirmed its effectiveness is much higher than conventional chemical treatment conducted on mice.

' It is an area that is progressing in a very impressive way ' - Piotr Grodzinski, Director of the Alliance for Anti-Cancer NANO Techniques - a directing organization of the US National Cancer Prevention Institute, confirmed. Receive and conclude: 'This technique can solve problems that previous techniques could not solve'.
