“Exclusion zone water forms on arterial walls and acts as an impenetrable barrier that prevents LDL cholesterol, red blood cells, and other large blood components from accessing the arterial endothelium.”

The existence of the exclusion zone (EZ), a layer of water in which plastic microspheres are repelled from hydrophilic surfaces, has now been independently demonstrated by several groups. A better understanding of the mechanisms which generate EZs would help with understanding the possible importance of EZs in biology and in engineering applications such as filtration and microfluidics. Pollack theorizes that water in the EZ exists has a different structure than bulk water, and that this accounts for the EZ. We present several alternative explanations for EZs and argue that Schurr's theory based on diffusiophoresis presents a compelling alternative explanation for the core EZ phenomenon.

In addition to small particles, there is evidence that the EZ excludes relatively large molecules such as pH-indicators and biological molecules.

The glycocalyx also plays a critical role in regulating LDL transport into the arterial wall, although the exact nature of the interactions between LDL and the glycocalyx is still under investigation... Reducing the thickness of the glycocalyx, or decreasing its barrier function would both favour the access of LDL to the endothelial surface, expose endothelial receptors and enhance binding of monocytes... which lead to enhanced accumulation of LDL into the intima.

In this study, we show that, in contrast to oxLDL, exposing human aortic endothelial cells (HAECs) to elevated levels of LDL results in a significant increase in both total and free cholesterol levels.

LDL transcytosis across the endothelium and its retention in the arterial wall is the initial event of atherosclerosis. Caveolae, ALK1 and SR-B1 are key regulators in endothelial LDL transcytosis and the progression of atherosclerosis. The study published in the journal Nature reveals for the first time how a protein called SR-B1 (short for scavenger receptor class B, type 1) ferries LDL particles into and then across the endothelial cells that line arteries.

Uptake of low density lipoprotein (LDL) by the arterial wall is likely to play a key role in atherogenesis. Due to this imbalance, LDL convection toward the luminal surface of the endothelium is likely to be far greater that the rate of transendothelial LDL transport, resulting in the formation of an LDL-rich (concentration polarization) layer adjacent to the endothelial surface. The dominant route by which LDL crosses the endothelium and enters the arterial wall is unknown.

Gerald Pollack's pioneering research revealed that water adjacent to hydrophilic surfaces spontaneously organizes into exclusion zones—regions where colloidal particles, solutes, and even ions are effectively expelled. These EZs can extend remarkably far from surfaces (up to hundreds of micrometers), defying conventional diffusion-limited expectations and suggesting long-range ordering mechanisms. Key experimental properties include: Solute exclusion: EZs are virtually free of dissolved particles and macromolecules.

The first regulator of LDL transendothelial passage is the glycocalyx, a thick and negatively charged matrix layer, that lines the inner wall of healthy blood vessels. Once through the glycocalyx, LDL can cross the endothelium via transcytosis, a process that occurs through vesicles, which transport lipoproteins from the apical to the basolateral aspect of ECs. In animal model, LDL may also cross the endothelium through the paracellular pathway, when the barrier 'leaks'.

Excess LDL filtration and accumulation in the subendothelial space are important events in early atherogenesis. It has been well established that there are three pathways for LDL transport across the endothelium: transcytosis in vesicles, paracellular transport through the breaks in the tight junction strand and leaky junctions associated with cell turnover or apoptosis.

The Pollack lab found that when liquid water abuts a hydrophilic surface, constituent water molecules split. The negatively charged components form an annular shell within the tube... As the protonated water exits, fresh water enters from the opposite end of the tube, perpetuating the flow. Our hypothesis was the extra energy that is needed is supplied by the EZ that lines the capillaries and supplies energy to drive the blood flow through.

Dr. Gerald Pollack, Professor of Bioengineering at the University of Washington, shares insights from his groundbreaking book, The Fourth Phase of Water. He introduced "EZ water" (Exclusion Zone water), a structured form of water (H3O2) that forms upon contact with most surfaces and differs fundamentally from conventional H2O. This unique phase generates an electric charge, offering energy with potential applications in medicine, agriculture, energy production, and health.

Our cells are filled with so-called “fourth phase” water, not liquid water. It's easy to demonstrate that by examining a cut in the skin. If cells contained liquid water, the water would pour out of the cut as from a breached water pipe. But it does not. Water in the cell is gel-like — a distinct characteristic of fourth phase water or exclusion-zone water, aka EZ water, which sticks to the solids inside the cell.

Atherosclerosis is the medical term for the waxy buildup that occurs on your artery walls, leading to what's colloquially called “hardening of the arteries.” LDL cholesterol is called the "bad" cholesterol because it can build up on the artery walls, making them hard and narrow.

Researchers have discovered that there is a fourth phase of water. This researcher is Dr. Gerald Pollack. He discovered that there is a fourth phase of water and this phase of water is more like a gel-like water or plasma, an electric plasma. This structured water is what is inside our human body and creates health in our body is called fourth phase water or exclusion zone water or EZ water, or structured water as the water forms a lattice-like structure.

This fourth phase was discovered by water researcher Gerald Pollack of the University of Washington and describes a gel-like state between liquid and frozen. However, this exclusion zone of the newly discovered water structure is only a thin layer in which the water begins to self-organize near hydrophilic surfaces. It also purifies itself, pushing all dissolved substances into the normal water layer. Hence the name "exclusion zone," as all substances and protons are displaced, i.e., excluded from this layer.

Endothelial cells line vessels. All of them have fury projections called glycocalyx that are rich in sulphate and this create maximum surface area on which to form exclusion zone (recall that EZ is neg charged). The red blood cells have a negative charge called zeta potential. When the RBCs have a good zeta, they will repel one another and stay as single entities.

Researchers such as Dr. Gerald Pollack have demonstrated that water in living systems does not behave like ordinary H₂O. Instead, it can enter a unique fourth phase—known as exclusion zone (EZ) water—a structured, gel-like state that forms adjacent to hydrophilic surfaces, carries a negative charge, and has the ability to store energy and transmit information.

Gerald Pollack's work proposes EZ water forms on hydrophilic surfaces including biological ones, excluding microspheres and other solutes, with applications suggested to arterial walls preventing clotting and atherosclerosis, though this remains controversial and not mainstream consensus in vascular biology.

The glycocalyx is these little hair-like projections that's on top of your endothelium. And the endothelium is like your inner coating of your artery walls. What protects the endothelium is this glycocalyx. You know that's negatively charged and red blood cells their job is to basically transmit energy to your cells.

This fourth phase of water was first identified by Professor Gerald Pollack and his team from the University of Washington. Investigating the behavior of water against hydrophilic surfaces, Pollack found that the water against the water loving surface behaves differently. He termed it EZ Water or exclusion zone water. A robust zone of EZ structured water lining the outside of a cell and within the cell has been associated with healthy cells while diminished EZ water outside and within the cell has been seen in cancerous cells.

This is known as 'Exclusion Zone water' (EZ water) because it acts like a physical barrier and excludes solutes (other substances in the water). The negative charge of the EZ water acts as a physical barrier to the contiguous hydrophilic surface.

An exclusion zone water since it excludes things it excludes solutes. um what you're going to do is you're going to produce a a very strong repulsive force against the blood vessels. and this is going to help to stop them from sticking on the blood vessel. wall. The structural walk water blanket provides a smooth slick layer which the blood can which the blood cells can freely pass.

Structured water forms in the outside hydrogen ions in the middle. The exclusion zone water acts as a barrier because it's exclusion zone and so again structured water forms on the lining of arteries.

That water can become this gel-like water on the lining of the arteries because in order for structured water to form it needs water, energy, and a biological surface. It will create the most exclusion zone fourth phase water in the body specifically on arterial walls.

Optimal hydration plays a key role in improving blood flow, reducing the strain on the heart, and supporting overall heart health. General hydration benefits blood flow but does not reference structured water or exclusion zones as arterial barriers.

The phenomenon of exclusion zone water (EZ) refers to the inability of large solutes, such as colloidal particles, to approach various hydrophilic surfaces in aqueous solutions, forming an "exclusion zone" tens to hundreds of micrometers thick. The currently proposed theory suggests that special structured water forms here. However, experiments by Taiwanese scholars using magnetic beads showed that they *could* penetrate the EZ zone. Therefore, it is proposed that EZ is caused by a combination of diffusiosmosis and diffusiophoresis.
