Relationship Between Nanoplastics and Lesions



 A team from Zhenjiang Agriculture and Forestry University in China is studying nanoplastics. They have discovered the relationship between nanoplastics and tissue damage.

Plastic usage is way up, reaching a staggering 390.7 million metric tons in 2021. There’s a major elevation of microplastic pollution because of this usage. The plastic accumulates in soil, water, food and even human tissue.

Methods to analyze MNPs (Micro/Nanoplastics) Are not widely available. Data that links MNPs to disease are necessary for the future. A study was released in TrAC Trends in Analytical Chemistry. The study was titled “ Mapping micro(nanoplastics) in various organ systems: Their emerging links to human diseases.”

Researchers collected 840 related articles on toxicological mechanisms. Their data came from microscopy and spectroscopy as well as other methods. The goal was to identify polymer types in tissues. The scientists studied oxidative stress, and inflammatory responses. 

The study found MNP’s are in skin, arteries, veins, thrombi, bone marrow, testes, semen, uterus, and even placenta. The plastics were found throughout the digestive system from saliva to gallstones. The plastics were also found in lung tissue and fluids.

There is a relationship between a large amount of particles and specific diseases. These are thrombosis, cervical cancer, fibroids and inflammatory bowel disease to name a few. 

An important part of the data states that the concentration of MNP’s is higher with tissues that have lesions versus non-lesion tissue. These can include cancerous growths, fibrotic lungs, and intestinal issues.

MNP’s contribute to oxidative stress and cellular damage. This can worsen tissue lesions.

There are no standardized techniques for the removal of micro plastics from the environment or the human body. Currently scientists are working on the removal of microplastics from the environment, but we need more strategies for removal from the human body as soon as possible!

Mike Giradi from Stereotimes commentary on Holostage Room Treatments

I have been  friends with Mike Giradi for a few years and he has helped me test numerous designs .    I was so honored a few weeks ago when he agreed to give these Holostages a few words.  From. Mike G. The sound was a little closed in at first, but then it really opened up to prove it is another great audio product. The noise floor is greatly reduced. I am hearing details I've never heard before. When it's in the recording, the soundstage widens in all directions. The timbre of each instrument is spot on. The six Holostages installed in my room aided in the C13 alignment of air molecules to a far greater extent than the Bybee IQSE devices I had previously been using. Every instrument had greater depth, pop and presence. Listening to classical music on movie soundtracks is incredible now. The Holostages installed on my BACCH4MAC and monoblocks was the answer to what was needed. The noise floor dropped significantly in both cases resulting in greater clarity and music...

Queen Bee 🐝

Image
  Bees hide an interesting secret. When the hive loses its queen, who alone is able to give life to the colony and maintain order in a perfectly organized society, all seems lost. The life of the hive slows down. Without new eggs, the future is lost. In a few weeks, the colony may be doomed. But the bees do not panic. Nor do they expect salvation from outside. Demonstrating extraordinary collective intelligence and profound instincts, they trigger spectacular emergency procedures, almost unimaginable in a world dominated by insects. --- ◆ The transformation begins with a simple but essential choice The worker bees choose common larvae - those who would normally be mere workers. They are nothing special. They are not born different. But their fate changes completely. They are chosen to receive a special food: royal jelly. A rare substance, produced by healthy bees, rich in proteins, vitamins and bioactive compounds. This is royal food in the purest sense of the word. The larvae fed ...

New Highly Conductive Polymer

Image
A new study from an international research team was published in the journal nature. The team has created a multi layered two dimensional polyaniline (2DPANI) crystal. The material has a unique metallic out of plane charge transport and is highly conductive. There are many different types of conducting polymers, such as polyaniline, polythiophene and polypyrrole. These polymers are best known for their electrical conductivity. They are low cost, flexible and lightweight, making them a possible alternative to traditional metals and semiconductors. Charge transport between polymer chains has been a huge challenge that scientists are addressing. Researchers from the round the world are collaborating, including Ningbo Institute of material technology and engineering (NIMTE) Of the Chinese academy of sciences ( CCAS), TU Dresden, The max Planck  Institute of microstructure physics and CIC nanoGUNE BRTA. They have developed a new 2DPANI crystal. They used a topology directed 2D depolymer...
