Can nanoparticles and other pollutants have connections with Alzheimer's?

Can nanoparticles and other pollutants have connections with Alzheimer's?

"For many years, scientists believed that fat in the brain had little connection to neurodegenerative diseases. Purdue University researchers are now challenging that view." (ScitechDaily, New Research Overturns Decades of Thinking on Fat’s Role in Alzheimer’s)

"Their study, published in Immunity, demonstrates that an accumulation of fat in microglia, the brain’s immune cells, weakens their disease-fighting capacity. The discovery points toward new therapeutic strategies in lipid biology that could support microglial activity and improve neuronal health in conditions such as Alzheimer’s. The work was led by Gaurav Chopra, the James Tarpo Jr. and Margaret Tarpo Professor of Chemistry and (by courtesy) of Computer Science at Purdue."

Researchers noticed. There is a connection between Alzheimer’s and nanoplastics. There is a possibility that pollutions simply block small blood vessels in the brain. And that causes a situation where dirt starts to accumulate in those blood vessels. That thing can decrease and block nutrients. From cells that those small capillaries should feed. 

So could the nanoparticles cause Alzhemers's in the same way as smoking cigarettes causes coronary artery disease? In those cases, nanoparticles simply block the coronary arteries. That causes. The heart and its muscles don’t get enough nutrients and oxygen. This can explain why alcoholism also causes those diseases. Alcohol dissolves fat that will suck in blood vessels. And that can cause heart attacks and also things like Alzheimer’s. Alcohol also dissolves proteins from the myelin cells’ shells. And that lets dangerous plaque move between those cells. That plague can jam the myelin cell’s ability to take nutrients by blocking its ion pumps. 

If the blood vessels are jammed, that means the cells that the blocked blood vessel feeds get without nutrients. When we think about Alzheimer’s, there is a possibility that the microplastics can be stuck in the small blood vessels in the brain. Those microplastics cause a point to form in the blood vessels. That starts to accumulate impurities at that point. That means Alzheimer’s can be similar to coronary artery disease. Some kind of dirt in the blood vessels blocks them. And if that happens in the blood vessels. That feeds brain cells. That decreases those cells’ ability to get nutrients and oxygen. This decreases their ability to accomplish their mission.

The reason why nanoparticles can have a connection with Alzheimer’s is simple. Those particles can block the smallest blood vessels in the brain. When blood flow in those small blood vessels slows or becomes difficult, this can cause an effect. Immune cells cannot reach all areas of the brain. And that causes the accumulation of the plague. The model goes like this. In normal brains, blood vessels are large enough. The immune cells reach all brain areas. Their mission is to remove zombie cells and other things. And if immune cells have no access to all brain areas, that forms blocks and plaques in those areas. 

Like metabolic waste that cells form in metabolism. Even if neurons are well protected against infections. The myelin cells that feed neurons are where Alzheimer’s forms. Things like sniffing glues cause situations where there are holes in the myelin structure. And then the plague can slip through this protective muzzle.  Some of those holes can also form, if the myelin cell turns overage. 

Another case is that the small particles can cause Alzheimer’s. Because those particles don’t allow the immune cells to clean the farthest points in the smallest blood vessels. If things like fullerene slip into the blood vessels, those things form bubbles in the blood plasma. And those ball-shaped carbon molecules can also slip into the cells, and if there is some kind of acoustic effect that puts the fullerene into oscillation, that oscillation forms millions of bubbles in the blood vessels. 

Those bubbles can jam the blood flow. Or they can destroy the immune system’s cells. They can affect another cell type’s internal structure. If small particles. Slipping into the myelin cells, it can cause a situation where the cell cannot get enough nutrients.  In the same way. If the cell that transports nutrients is filled with bubbles, that means it cannot carry enough nutrients to the cells. 

Bubbles are always dangerous, because they can decay. When the oscillating membrane pulls the bubble larger, that causes an effect where a low-pressure area forms around that bubble. The low-pressure area causes a situation where a small part of the fluid boils. And that effect forms more bubbles. When there are enough bubbles in some blood vessels, they simply block those vessels.

New materials require new tools.

New X-ray systems make it possible for researchers to observe. How electrons change their trajectories when they send photons. When molecules form, those systems can observe how atoms flip their electrons. Those systems really see atoms. They see when the atomic nucleus will turn around. In the atom. And the highly accurate photon beams can control those processes. The ability to see how chemical bonds form, and where electrons really are. Makes it possible to create new materials. 

The highly accurate systems can manipulate single electrons around atoms. And that makes it possible to create things like atom-sized quantum computers. These kinds of systems. Those connected with algorithms and quantum computers make it possible to create new types of small robots. Those robots are smaller than a cell, but high-power quantum computer technology gives them abilities. That can beat large-sized systems. 

The problem with the X-ray impulses is that they can destroy entire molecules. The accuracy of this ksystem, which breaks the entire protein molecule, is incredible. In medical use, that system can break down tumors and blood clots. The problem is how to aim those X-ray impulses at the desired point. The single X-ray radiation burst can terminate complex molecules. This can also make it possible to create systems that break unwanted molecules. Like carbon chains, fullerene, and graphene. Those things are harmful in nature. The system can stress those carbon atoms and make standing waves between atoms. And that can destroy carbon bonds.

Researchers want to create the first neutrino laser. 


MIT physicists want to create the most incredible tool that humans have ever created. The simpler way is to trap neutrinos in the tank. And then shoot them forward using lasers as accelerators. Photons will bomb those neutrinos and make them move forward. That makes it possible to create new types of quantum communication tools. And if neutrinos can be put into superposition and entanglement. That gives new possibilities for quantum computing. 

But there is a possibility of using neutrinos to send electromagnetic radiation. Those kinds of systems are tools that can make new observation tools possible. 

They aim to develop a neutrino laser. The concept in that system is the same as in free-electron lasers. The system pumps energy into the neutrino cloud, and those particles will send energy beams, or photons, to make the beam. Those systems can be used to scan atoms with incredible accuracy. The system’s biggest problem is how to trap neutrinos, which are very weakly interacting particles. That trap can be made using laser beams that create an energy point. That doesn’t let those neutrinos get out. Then another laser or other electromagnetic radiation can send energy stress to those neutrinos. 

Another way to create a neutrino laser could be a system that traps neutrinos in graphene. And the system sends energy stress to those things. The neutrinos at the bottom of the fullerene tube send radiation forward, and the neutrinos. That is around that structure, which pumps radiation to a beam that travels through the nanotube.

The possibility of creating graphene, or other 2D material layers. That can trap neutrinos, making it possible to create a radar that can see atoms from a new perspective. In some ideas, the neutrino can be trapped in a photon. The photon forms the tensor that is used to send energy signals to the neutrino. And the neutrino sends its extra energy to that photon. The system senses changes in photon brightness.
