Artificial viruses bring new winds in medical treatment.

The new biological sciences and genetic applications are impressive. Things like 3D collagen can help to print living tissues and maybe organs. The system can make 3D bioprinting using normal bioprinters.

And the problem is where to get those cells. If those cell's shell antigens are wrong, the immune system destroys those cells immediately. 

When researchers want to make things like bioprinted bones they need lots of cells. And one answer to that problem is cell reprogramming. In that process, the system changes the DNA from the cell's nucleus. The problem is how to make enough cells in a short time. 

Because if people need that kind of thing, that happens in non-predicted accidents. The system must make a number much cells in a short period. The answer can be the artificial viruses that can make that reprogramming process. 

If researchers want to print a 3D organ like the liver or even the brain the system can use large-scale cell reprogramming. The idea is that the system puts those cells in the 3D mold. 

Then the artificial viruses can reprogram those cells by removing their DNA. Changing those DNAs into new ones the virus changes the type of the cell. 

That should transform those cells into the wanted tissue and organ. This kind of therapy makes it possible to turn even bacteria into the tissue that replaces the old one. 

The new knowledge of the cells and bacteria. And their DNA makes it possible to manipulate cells. And their operations with new and effective accuracy. 

Another thing that researchers noticed. The cell's role in the human body depends on the nutrients and metabolism. This knowledge can make it possible to create artificial tissues using cell cultures and boost things like immune systems. 


The growing knowledge of the DNA sequences. And their effect on cells. 


Make it possible to create cells. That transforms themselves and their roles. The same cell can destroy bacteria. And then it can act as the building block of the blood vessels. 

The artificial immune cells can transport bacteriophages to the desired point in the human body. 

Those viruses can search and destroy non-wanted cells. 

The AI is the tool. That can search the DNA sequences in a very short time. The AI can see people's DNA and find out why somebody will not get the flu. 

The artificial cells and bacteriophages can replace many antibiotics. But before we can say "goodbye" to antibiotics. We must have complete information about the mechanisms. That the bacteriophages use, when they target bacteria. That mechanism helps to find or create artificial viruses that can target things like cancer cells. 

The human gut has its bacteriophages the mission is almost certainly to make sure. That the gut bacteria are in balance. 

By following those phage viruses researchers can get more information about how the phage selects the bacteria. And maybe in the future, those bacteriophages can also transfer DNA bites that cause bacteria to die. More or less artificial viruses can be used to destroy non-wanted cells. 

And researchers think about the possibility. That they can remove those phages from the gut. During antibiotic treatment. Then they will return those viruses to the gut by using genetically engineered cells. Those cells create phages.

Another thing that those phages can do. It turns the immune defense stronger by helping immune cells destroy bacteria. That they cannot otherwise reach. The intestine is a hard place for the immune cells. And maybe those phage viruses handle immune cell missions in the intestine.   But otherwise, they can make the gut bacteria more vulnerable to antibiotics. 

Artificial viruses are excellent tools for genetic therapy. Artificial viruses can also boost the killer cells's ability to find the non-wanted cells. The idea is that. 

The virus can carry the DNA, or mRNA bite. That gives immune resistance against some antigens. That thing can boost an ability to fight against cancer. The mRNA programs the immune cells to select and destroy things like zombie cells. 

The hope is in so-called NK (Natural Killer)-cells that memory is enhanced using the mRNA or some kind of microchips. This requires precise operating systems that can select non-wanted cells more accurately than before. But that requires very highly accurate genetic engineering.

The writing about stable carbon ring, medical technology of tomorrow and nano-submarines


 The writing about stable carbon ring, medical technology of tomorrow and nano-submarines 

The stable carbon ring would make a revolution in nanotechnology because this technology can be used to create smaller and smaller nano-size microprocessors, where the transistors are created by using three atoms. That means that the base, collector, and emitter would be created by using single atoms, and the atom-thin fibers, what are created by using carbon or carbon atom lines would make possible to create the systems, what are more effective than we ever imagine.

https://en.wikipedia.org/wiki/Nanosubmarine

But the carbon ring would be possible to create more effective instruments for nanotechnology, and they can be used to take samples from the human body from the places, what are unable to catch by normal instruments. The thing is that those nano-sized rigs can capture single molecules or cells from the body, and if it is connected to the miniaturized submarine, it can bring the sample to the researchers.

The nano-submarines are the future version of the endoscopes, and they can swim inside the veins of the patient, and search non-stop the influence of medicine and also find the suspected cells and other things like viruses from the body. The nano-lasso can also take viruses to the laboratory, but it can also help the human own immune system to fight against other organisms. In this scenario, the nano-submarines would take the T-cells to the bacteria and another infected place in the human body. That will make possible to teach the immune system to fight against those cells, what might harm the body.

But the nano-lasso can also use with the miniaturized trawls and those systems might be used to remove the dangerous bacteria from the body. The thing is that caries bacteria would cause Alzheimer disease because it would create plaque in the nervous system. If that bacteria is released in the blood system, it can deliver plaque, and the problem is that plaque would be effective even if the bacteria would die. And the nano-trawl would release those cells from the body.

The thing is that even we would use antibiotics, those cells would be dangerous because some bacteria would start to create plaque and divide if they are treated by using some harmful chemicals. I don't know is the caries bacteria one of those organisms, but it would be one of the organism, what should remove by using some other method than the chemical destroyer. The thing is that the trawl can transfer the bacteria out of the body without waking its defense is fascinating.

But when we are thinking about those nano-submarines, they might also involve small laboratories and the submarine can pull a single bacteria or virus in its chamber, and then it would introduce that organism to immune cells. The size of those submarines would be extremely small, and they might make by plastic silicone, which allows them to change their form. And the detectors would see, how the cell is handling the harmful organisms.

That means that the immune cells would be chosen for the battle, the way that the submarines will transfer only the cells what are effective to the infected area. But this kind of things are visions of tomorrow medicals, what are basing the nanotechnical solutions and the use of state of art computer technology, what would control those machines in the body. In the most fascinating ideas, the systems would get their electricity from the human nervous system, which makes them operate very independently.

The thing is that nanomachines and observation systems might operate inside the body even a person is out of the hospital. And the system can communicate with the mobile telephone by using miniaturized WLAN-and computer technology. They could use the mobile device for communicating with the medical team, and external computers can give calculation assistance to the nano technical robots, which are operating inside the human body.
