That's me, getting a nasal lavage.

Meteorites delivered chemistry, and perhaps membranes, too.

And I found I could do it with a nasal inhaler.

That's your articular cartilage, and those are your synovial membranes.

For this fish, it's actually whole cells with nuclei and membranes.

These membranes are also quite similar, morphologically and functionally, to the membranes in your body, and we can use these, as they say, to form the body of our protocell.

And I present to you a concept that these are extended neurological membranes.

A company called Aquaporin is starting to make desalination membranes mimicking this technology.

Actually, we thought the nasal tract might be full of viruses even when you're walking around healthy.

And in nature there are lots of examples of very efficient structures based on pressurized membranes.

Heart rates are slower you live longer diffusion of oxygen and resources across membranes is slower, etc.

The nasal cavity is unique, as the only place where brain cells (neurons) are directly exposed to the environment. If we model smell on local terms, we can trace how nasal neurons interact with scent particles, sending signals through a network of other neurons to the brain.

Solid substances (powders) may become corrosive or irritant when moistened or in contact with moist skin or mucous membranes. .

And just to give you a sense of how this works, imagine that we took a nasal swab from every single one of you.

But those bubbles have membranes very similar to the membrane of every cell of every living thing on Earth looks like, like this.

In part, amphibians are good indicators and more sensitive because they don't have protection from contaminants in the water no eggshells, no membranes and no placenta.

(b) Subjective human observations could be supported by objective measurements of clear respiratory tract irritation (RTI) (eg. electrophysiological responses, biomarkers of inflammation in nasal or bronchoalveolar lavage fluids)

Aspiration means the entry of a liquid or solid chemical product into the trachea and lower respiratory system directly through the oral or nasal cavity, or indirectly from vomiting

I've been a scanning electron microscopist for many years, I have thousands of electron micrographs, and when I'm staring at the mycelium, I realize that they are microfiltration membranes.

And all I wanted to show you is we can set up molecules in membranes, in real cells, and then it sets up a kind of molecular Darwinism, a molecular survival of the fittest.

Because these anatomical features persist into early childhood, the dura may remain similarly vulnerable to bleeding beyond the newborn period. Indeed, both birth related bleeds and those attributed to shaking are most often located in the folds of membranes covering the brain that have more and larger blood vessels at this age than later in life.

The publicity and resulting panic surrounding the WHO s announcement of Phase 5 and 6 alerts especially in the absence (until December) of widely available vaccine also brought out fraudsters peddling all sorts of ineffective and possibly dangerous protective gear and nostrums gloves, masks, dietary supplements, shampoo, a nasal sanitizer, and a spray that supposedly coats the hands with a layer of anti microbial ionic silver.
