3D printing of organs

Reading Time: 2 minutes

Animals have previously been successfully printed organs using a 3D printer. Northwestern University researchers inserted prosthetic ovaries in sterilized mice, and the animals produced healthy offspring. Rhesus monkeys have been implanted with blood vessels made from the same animals’ material at the Chinese business Sichuan Revotek.

Different bioprinting technologies are being developed by research organizations or companies: 

Frame. The inorganic proliferation of living cells, which vanishes with the formation of natural connections between cells. The key challenge is finding a material that is equally flexible or stiff as the organ to be replaced. It must decay fast in order to avoid interfering with the extracellular matrix’s strength and dissolve without leaving hazardous substances behind. Wireframe printing is possible using hydrogel, titanium, gelatin, synthetic, and biopolymers. 

Frameless. Ready-made cells are applied to a hydrogel foundation. The cells are chilled and housed in thin hydrogel spheroids while they are in the printer. The temperature rises to 36.6°C during printing, the spheroids scatter, and the cells build their own natural framework – the cellular matrix. This type of printing is less prevalent than wireframe printing since it was developed later and is more difficult to duplicate. 

Mimicry. Future technologies will allow for the simultaneous production of entire organ replicas. Bioprinting at the molecular level is being developed for it, as are in-depth studies of cell nature. 

3D bioprinting has progressed from an idea to a viable commercial product. Bioprinting firms’ principal clientele to date have been huge pharmaceutical enterprises. Drug testing is sped up by testing drugs directly on printed human tissues. 

Although expensive bioprinters will not be available in city clinics for another five years, 3D printing is already helping some patients heal. Osteomyelitis infected the jaw of an 83-year-old Belgian lady. The repair was more costly and took longer than removing the sick jaw and replacing it with a printed replacement. The procedure was conducted by a team of doctors led by Professor Jules Poukan, and the woman was able to communicate shortly thereafter.

With the advancement of bioprinting, it will be easier to remove a damaged limb and generate a new one than it will be to treat ailments that are currently treated without amputation. Bioprinting is appealing to cosmetologists and plastic surgeons, in addition to doctors. The desire to stay youthful and attractive, rather than the treatment of uncommon and complicated diseases, will drive the adoption of 3D printing of human organs. Perhaps, in the future, individuals will be able to replace their organs and looks as simply as they change their cellphones.

Cyber delivery in real life!

Reading Time: 2 minutes

In ancient times people used birds to deliver mail, and it took much time to deliver it. Nowadays everyone uses online services for mail. But post offices still exist. They deliver things from online shopping. In some countries to get a package, it is necessary to go to the post office. In Poland, some of the packages are possible to deliver not far from home, thank the Poczkamat. But not every Poczkamat is located comfortably. What if I say that there is a service that could deliver a package right to your entrance. It is a Yandex delivery.

Yandex Rover delivers in Ann Arbor - YouTube

It is important to say that it works just in Moscow, and it is in the process of testing this service. However, Yandex uses robots to deliver packages from the post office. How it works? A person buys something at the online store with delivery to the post office, and he, she or it could use Yandex delivery to deliver their package to the entrance door. Worker at the post office put package into a robot and it rides through walking paths to the customer house. When it has arrived, at the smartphone of the customer a notification arrives. The next step is that customer go to the robot and open it’s luggage compartment and user could get his package.

It is really new step in delivery business, pakcge will come faster, more comfortable, and it is less probability that worker will lose a package during delivery.

But there are some problems with these robots, so they can not work correctly during winter, because of snow and cold weather, they just discharge in half an hour and someone has to charge it. Some of ways goes through the roads, and drivers could hit it because its hard to see it.

To sum up, it is really good technology that could bring new step in delivering business, but it has to be proved by companies, and government should take some steps to make more speed bumps next to pedestrian crosses, that will help to drivers, that probability of hitting such a robot will drop.

The new type of Vaccines

Reading Time: < 1 minute

“An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response” – Wikipedia

It is a new type of developing vaccines. Earlier vaccines were developed in another way, it is called vector vaccine

“You take a virus [vector] – a harmless, non-intruding into the genome, with which all humanity encounters during its life – adenovirus. Then you make him even safer – you cut off a piece of his genome, or rather two.” – Deputy Director for Scientific Work of the Center. Gamalea of the Ministry of Health of Russia Denis Logunov.

Today there are two mRNA vaccines: Pfizer and Moderna. Both of them against Covid-19.

So, the important question is why this technology is so important or innovative? I will give you an answer in this blog.

Firstly, vaccines that were made in mRNA way could be easily modified for new virus stamps. Secondly, they are more effective than vector vaccines (effectiveness of Pfizer and Moderna more than 95% while vector vaccines have less than 90%). The third thing is that this technology gives us hope that in future we could get vaccines against Cancer, HIV and other serious illnesses.

The opposite view is that this technology is young, just few years. No one knows how it will affect our health in future, so that why using such vaccines should not be introduced by force or by threat. A person should introduce it if he wants to.

My personal view is that this technology started well and will provide to humanity with a lot of good things and will save great amount of people. And i was vaccinated by Pfizer , because i belive in this technology.

Virtual reality

Reading Time: 2 minutes

Virtual reality is a new technology. “The term “virtual reality” was first used in a science-fiction context in The Judas Mandala, a 1982 novel by Damien Broderick.” – Wikipedia. So and now there are devices that give us an opportunity to plunge into this reality.

Film Review: "Ready Player One" - UCSD Guardian

Nowadays Virtual reality used in several industries, for example medicine.

“Therapeutic virtual reality (VR), the use of the immersive, computer-generated technology in medicine, is on the fast track to widespread use. In some hospitals and clinics, your doctor can already prescribe a visit to a VR world to ease your pain or anxiety or to explain a complex medical procedure or condition.” – source https://www.webmd.com/a-to-z-guides/features/virtual-reality-medicine.

or some surgeons can practice before a complex operation and in some hospitals doctors already use VR during operations, where is impossible to use human hands and thumbs.

“The virtual reality system is helping train residents, assist surgeons in planning upcoming operations and educate patients. It also helps surgeons in the operating room, guiding them in a three-dimensional space.
Paul Sakuma” – source https://medicalgiving.stanford.edu/news/virtual-reality-system-helps-surgeons-reassures-patients.html

On the other hand, VR used in the entertainment industry: games, videos, movies and so on. It gives customers new sensations, but it could provide an addiction to this games. In VR games people could be anyone: a person, an Alien even a rock with Legs. And this possibility to be anyone could be dangerous. This problem was showed in movie “Ready player one” where people were playing in VR game and did not work, just playing this game.

Until everyone get such VR games it is hard to say if this technology would give more Pluses than minuses. Personaly, i believe that it would bring more pros, because i can compare this technology with telephones. everyone use them now, but few decades ago people said that we would not live normal live with them, we would be playing all the time and we need to destroy them. And now, telephones helps us in live, we could communicate with our friends and travel during our work, if it is online. So i hope the same thing will be with VR technology)

STARLINK

Reading Time: < 1 minute

STARLINK IS NEXT GENERATION PROVIDER OF INTERNET, OPERATED BY SPACEX.IDEA OF THIS PROJECT IS SIMPLE, TO GIVE INTERNET ACCESS TO EVERYONE ON THIS PLANET ANYWHERE. NOWADAYS 1600 SATELLITES ARE USED, PROVIDING THIS TECHNOLOGY AND IT AVAILABLE IN 20 COUNTRIES IN THE WORLD.

COUNTING PLUSES OF THIS CONCEPT I CAN MENTION THE FOLLOWING:

  1. AVAILABLE IN REMOTE AREAS.
  2. HIGH SPEED OF CONNECTION

THEY ARE IMPORTANT, BUT THERE ARE MINUSES SUCH AS:

  1. EXPENSIVE CONNECTION AND USING
  2. NOT ENOUGH COUNTRIES

TALKING ABOUT SECOND DISADVANTAGE I WANT TO MENTION THAT IT IS IMPORTANT FOR FUTURE COST OF PRODUCT. MORE COUNTRIES, MORE CUSTOMERS, MORE MONEY FOR INVESTMENTS AND SO ON.

“actual service can be delivered only in countries that have licensed SpaceX”

TO SUM UP, IT IS GOOD TECHNOLOGY FOR FUTURE. WHEN HALF OF THIS WORLD WILL USE IT, ANYONE ONE COULD TRAVEL ANYWHERE WITHOUT ANY PROBLEMS, WITH GOOD INTERNET AND HIGH SPEED. AND THESE FUTURE REALLY CLOSE TO US
