Korean Red Ginseng Inhibits Articular Cartilage Degeneration

Recently, I read on a forum about these young Korean kids who are given some type of small green type pill by their mothers to help them grow taller. It is interesting that there is such stuff being sold for at least the last 30 years which supposedly would help young Asian kids grow taller.

Maybe the competitive nature of these East Asian cultures makes mothers try all sorts of rather bizarre things to help give their children any type of edge in life.

In the last two years of research, I personally have found at least 2 other different compounds which have been a part of Traditional Korean Medicine who has been believed to work in helping kids grow taller. Not only that, a group of Korean scientists filed a patent on a type of Ultrasonic-LED Combo type device which was supposed to stimulate the epiphyseal plates. It seems that South Korea, which has taken much of the older medical knowledge from Traditional Chinese Medicine, might have figured out a few natural ways to help its people end up slightly taller.

All this talk about Eastern Mysticism and the Esoteric made me wonder whether the Oriental Superpower Plant known as the Ginseng might have any type of chondrogenic or cartilage enhancing properties. After taking some time to look over PubMed, there were at least a couple of studies which validates this idea.

The active ingredient in all of the varieties of Ginseng, is this compound known as ginsenosides, which is in a category of compounds known as the saponin ,or more specifically the triterpenoid saponins. (For more information on Ginsenosides, refer here.) By last count, there is over 150 different kinds of Ginsenosides. From thousands of years of trial and error, humans found that they can orally consume the Ginseng and get the active ingredient inside the Ginseng to work. The Ginsenosides work in the stomach through acid hydrolysis and in the gastrointestinal tract by the reaction bacterial hydrolysis.

It seems that at least three of the over 150 different kinds of ginsenosides have some type of cartilage enhancing ability. I am quite sure that in the last century, multiple Asian researchers have validated the idea that whatever is in ginseng have anti-inflammatory effects. Inflammation is really the start of almost all types of cartilage degradation. If Inflammation is prevented, then the chances of the onset of osteoarthritis is going to be severely reduced.

In the first study, 11 different types of ginseng saponins were used. There were 2 which had some really powerful effects, ginsenosides F4 and Rg3. It is F4 which is really interesting. With increased dosage/concentration of the F4, the inhibition of the MMP-13, which is a collegenase, was increased, almost linearly in fashion. at 50 microMolars, the inhibition of not just the MMP-13, but also the p38 MAPK Pathway was also inhibited.

In the third study, it was found that the saponin was able to cause the number of chondrocytes in deficient mediums to proliferate and have the precursor stem cells to differentiate into chondrocytes{I believe that it was stating that it encourages differentiation of chondrocytes as in chondrocytes into hypertrophic chondrocytes not differentiation of stems into chondrocytes-Tyler}.

This is really interesting because for the longest time, many “grow taller pills” that were sold in places in South Korea (and maybe also China, Taiwan, Singapore, etc.) did have extracts of at least a little bit of ginseng in them. Is it really that far fetched for people to believe that the mystical ginseng plant would have some “special” ingredient that would also make them taller?

In the article “South Korea Stretches Standards for Success” published back in Dec. of 2009 in the New York Times, there was a really popular clinic called Hamsoa, which supposedly had already 50 clinics around South Korea, and they gave kids a special type of tonic which was supposed to be taken twice a day. Inside that tonic, was deer antler, ginseng, and other chemical compounds at a much lower concentration. Notice that deer antler and ginseng were mentioned.

It might be possible to use the ginseng to stimulate the activity in the growth plates of young kids, as well as even use the deer antler, but I am not sure how pronounced the stimulation would be. What can be well substantiated is that ginseng seems to help prevent cartilage degeneration and regular chondrocyte apoptosis.

My Personal Analysis On Tyler’s Claims On His Finger Bones Lengthening

My Personal Analysis On Tyler’s Claims On His Finger Bones Lengthening

So Tyler has asked me to do an exact measurements on the length of his fingers for about a month now. I finally got the time to stop by the local FedEx and asked them to print a blown up copy of all the X-rays that he has shown in previous posts. I chose the option of 24″ x 36″ and printed out all 5 of the pictures, all black and white. I took the prints home, cut out the edges, and checked the length unit standards at the bottom. When I looked at the centimeter scale, which is very much like a map legend, of the X-rays for the left and right hand, they matched EXACTLY. That means that making conclusive conclusions is much easier. I don’t need to multiply by some factor like 1.15 to make the lengths of one of the X-rays to match up to the other X-Ray to work out.

How I prepared the analysis

So I folded the blown up 24″x36″ picture of the X-ray of the right hand on the axis which is parallel to the right index finger. I placed the finger bones right next to each other.

I then used a US Based measuring tape and started to check the length of the bones at the exact center.

Here is what I did find

Based on at least have a dozen extremely, almost anally, specific measurements done on the center of the proximal part of the index finger for both left and right, here is what I found…

On the right index finger, in the proximal finger bone, it is only slightly longer than the left one. How small do I mean by “slightly”? First, the 24″x36″ blown up picture has the length scale at the bottom. Comparing the inches on my measuring tape to the scale, it seems that…

1 cm of the blown up is exactly = what is almost exactly in the middle between 7/8th and 15/16th of the inches of my measuring tape (aka 29/32th) —-> 1 cm = 29/32 inch

Length of the right index finger (measured from proximal end point to end point) – 3 and 9/16th of an inch

Length of the left index finger (measured from proximal end point to end point) – between 3 and 9/16th and 3 and 19/32th of an inch

Sometimes (maybe half of the time) the measurements of the left and right hand index fingers are exactly the same, but the other half of the time, the left index finger is slightly longer, but by maybe just 1/32th of an inch on my measurement tape.

Doing a little bit of converting of the units (and then canceling out the inches terms), we get…

 (1 cm)/(29/32 inch) X (1/32 inch) = 1/29 cm = .34 mm or a little over 1/3rd of a mm

The Result

After half an hour of measuring the same two parts over and over again, being a little too anal over the length, The conclusion is that the proximal bone in the right index finger is around 1/3rd mm longer than the one on the left.

Note: About half of the time I did the measurement, it does seem like that the length measurements for the left and right index fingers were exactly the same. The other half of the time, the right one was just slightly longer than the left one (usually just 1/32rd of an inch of the tape I had). At no measurement did I ever find that the left one was slightly longer than the right index finger, at least for the middle bone part.

What else did I find?

It seems that the most significant difference in length is at the tip of the fingers, on the distal end. The very small distal bone at the tip of the right index finger always seems to be slightly longer than the left one.

  • The length of the distal end of the right index finger = 1 and 1/2 inches
  • The length of the distal end of the left index finger = 1 and 15/32th inches

The suggest that there is a difference in the tips of the index fingers, by around 1/3rd of a mm.

Further Analysis

At this point, the results show only that 50% of the time when I would do a measurement, it seems that the most proximal phalanges of the right index finger is only about 1/3rd a mm longer than the left one. Based on those results, I would say that the difference can not be used as evidence that the bones in Tyler’s index fingers actually increased in length.

I did not take any statistics & probability courses back in university so I would not be able to do any type of statistical analysis. However, I can put things into perspective.

On average, the length of that specific bone is around 3 and 9/16th inches at the middle, measured from tip to tip. That converts to 3.5625 inches X ( (1 cm)/(29/32 inch)) = (3.5625*0.90625) = 3.2285 cm

That is the length of each of these bones. Divide the 1/3rd of a mm by 3.2285 cm and we find that the difference in length between the two bones being of opposite hands is just at 1% difference. If my measurements are right, then the right finger at least at the proximal one, is maybe 1% longer than the one on the left.

The Connection Between The Short Stature Of The Vietnamese and Their Diet

I might be stepping out of line with this post but a recent video I saw on Youtube made me wonder whether a certain tribe or ethnic group’s diet and eating habits might have a much larger influence to the height of a certain ethnicity.

I refer to the trip Gordon Ramsey takes to Vietnam in one of his Great Escape episodes. In the last month, I have started to enjoy many cooking channels, and Gordon is a very colorful, interesting character to follow. I don’t have a TV so I don’t know what is really popular on TV these days. It seems that this series of food traveling show has been around since 2010, and only now have I heard of it.

What really struck me was that in the episode where Gordon visits the country of Vietnam, two different people both talk about the lack of calcium in their diet. First, it was Mrs. Vi Ching and 2nd was the guy who Gordon was eating snake hearts with.

It is interesting that this Mrs. Vi Ching, who supposedly owns 4 of the most famous and well touted restaurants in all of Ho Chi Minh City and goes shopping twice a day for freshness made the offhanded comment that “We have no dairy, so we eat the bone for calcium”. Then when Gordon is out with a couple of the vietnamese men, the restaurant chef would fry up the backbone of the snake they ordered which was made into at least 4-5 different dishes. It was supposed to give them more calcium.

Refer to the video below…

So it seems that for the people in Vietnam who really focus on the food, they have a unique concern with Calcium and getting enough of it. Do they somehow realize that their diet intrinsically lacks the calcium (as well as the Vitamin D, K2, Iron, Amino Acids) that is needed to grow “normal”? Or maybe at least by American standards

In my personal life and my history of going to the various Vietnamese Restaurants, I do sort of see the connection. The Vietnamese do eat a lot of strange animals and delicacies, like frogs and snakes, which had a lot of lean, dark, and flavorful meat. The Vietnamese really care about Flavor and Texture, since the 2nd guy also made the comment that the Vietnamese prefer to eat food that has a little bit of chew to them. They focus on taste, but not utility and function. They eat what tastes good, but forget to eat what might be actually good for them and their bodies. They don’t seem to have that critical factor of dairy. Dairy is missing in their diet.

They might be eating cow and beef, but those are used sparingly. They eat shrimp, but there is little excess meat in their diet. The Vietnamese seem to traditionally like to eat out a lot, at the local Hole In the Wall, which are very cheap. That means that the food might not have the neccesary composition (vitamins & minerals) to give them to grow to their maximum potential. I mean, how nutritious can a Flying Bat or Snake be in terms of real nutrition?

So then, why is it that the Vietnamese are not consuming much dairy products? 

I don’t know. Maybe the forests of Vietnams have not been cleared out to make room for cows to graze in, unlike say the USA or Canada, which has a lot of available land. I don’t know what is the average native vietnamese person’s diet, and how much milk they were drinking when they were children who were still growing.

So some might ask me, does that mean that eating a lot of dairy like milk and cheese with higher than average calcium levels would make themselves taller? My previous research into this suggested that there is a positive correlation but the correlation is very weak. Even the 1-2 studies which support that positive correlation didn’t explicitly state out right that there was a positive correlation, but implied it.

Of course, I could , playing my own Devil’s Advocate, show that the Mongolians, who have no source of seafood, vegetables, or fruits, and live off of a diet of just meat (mainly sheep and goat) and dozens of derivatives of dairy products don’t seem to be shooting up like redwoods. I don’t hear about too many 7 foot tall Mongolians that are trying to get into the NBA.

Most people who analyze the factors which make up an individual’s height says that genetics has around a 60-80% effect on a person’s height. Traditionally, the idea proposed by geneticists is that if you are born to short parents or into what has been considered a short “ethnicity”, then there is nothing you can do about it especially in terms with changing one’s diet.

However, there has been multiple times in the last half decade where I have seen cultural trends which suggest that maybe diet and environment may play a much bigger role than believed.

I remember one time in a shopping center and two super tall females walked by me. Both of them were carrying 1 gallons of milk in each of their hands. When I commented them on their purchases of so much milk, one of the girls commented that where she is from, their diet strongly emphasizes dairy problems. I would found out after asking where she was from that she and the other girl were from an unknown city in Germany. Of course, I know from experience that not all full blooded German ethnic girls are above average in height or consume a lot of milk. It might have been just one unique case.

What I can’t write off is this phenomena seen in Denmark, the Netherlands and other Northern European nations where the standard of living is so good. We know from observation that it seems that “Asian” people are stereotupically shorter than say the “Average White American”. However, many sociologists point out that the difference in height is due to them being usually 1st generational immigrants. When these immigrants have children in their new country, with a better diet and healthcare system, the 2nd generational kids turn out to be much taller than them.

That is the phenomena seen in the Netherlands and Denmark, when babies are born of immigrant parents from say Turkey, Iraq, Egypt, Iran, etc end up MUCH taller than what was expected of them by their parents, who might be a little over 5 feet tall. The change in stature by just 1 single generation is staggering! . I don’t disagree that compared to the 100% in blood Ethnic Dutch, the Turkish Immigrants or say a Filipino immigrant might be much shorter on average. What happens almost always is that the immigrant’s kids turn out to be much taller. The height difference is reduced dramatically.

Sure, there is probably not going to be a way to test this out, with a set of identical twins, one raised in native Turkey or Iran, and the other twin living in Amsterdam, thus a control and the subject. However, I believe that most sociologist would agree with me that it SEEMS LIKE that if you grow up in a different country, your expected adult height changes, often by a lot, and even by a few standard deviations.

That would mean that one’s environment and most definitely the local food has a major influence on the kids’s development.

In fact, there is a phenomena seen in the East Asian community where immigrants who came to the Western countries (USA, Canada, Australia) later in life, say in their 20s almost could not get fat or overweight even if they wanted to and ate a lot, but their 2nd generation Asian Canadian (or Asian American) counterpart found themselves struggling with their weight their whole adult lives. At some point in the phase where the teenager turns into an adult, the body’s metabolism changes and the two groups of people who have the same ethnicity starts to diverge in their body shape, both in height and weight.

It seems like the diet that one eats when one is very young and in development dictates one’s adult metabolism level. I suspect that it has to do with the raising of the IGF-1 level in one’s system, and how well one’s body can produce and use insulin.

On average, I would say that above average in height adults in the USA are more likely to be overweight than average in height people and short people. That means that height and weight are positively correlated, pushing one’s BMI steadily higher over time, (since the factor of height is squared and divided over in the BMI Calculation)

What does this all mean?

It seems that the old stereotype of Asians being short may be explained much more by their traditional diet than previously believed. Based on this old World Health Organization report (Click Here for the PDF), it was shown that the growth pattern was almost exactly the same for all tribes and ethnic groups from around the world. That would suggest that if all ethnic tribes were places in the same environment with the same level of healthcare and had the same diet and eating habits, on average, they would have all the same adult height, accounting for the initial length and weight of the person when they were first born. (Multiple studies showed that people who are born big, grow to be bigger, since they start out initially with much more mass, aka many more chondrocytes which had condensated in their embryological development.)

Maybe the Vietnamese are shorter than average because of the lack of dairy products in their diet. I do believe that diet plays a much bigger role than I had thought a year ago. I did show once that eating the shells from a lot of Shellfish, or Shrimp, or Crayfish (Mini Lobsters), or any type of sea life based creature with a keratin/nail like exoskeleton might help in one’s growth pattern. It turns out that Glucosamine Sulphate, which was one of the biggest discoveries and posts on this website (Refer to that viral post here), is derived from the shells of shrimp and shellfish. Yes, technically Glucosamine Sulphate is a compound that is endogenously produced in the human body, but consuming it helps with making many joints in the body increase in thickness and volume, if ever so slightly.

If I was to say one thing about this point, it is that maybe a large factor for the differences in height in the various “races” and ethnic groups is due to their food choices, particularly the lack of dairy products when they were young.

Update 17 – Cartilage Degeneration Disorders – September 1st, 2014

Update 17 – Cartilage Degeneration Disorders – September 1st, 2014

First Issue

In the last month or so I have found out that certain close friends and family members, who are still extremely young, have already started to suffer from severe articular cartilage degeneration. It seems that the phenomena of cartilage degeneration is a much, MUCH more prevalent medical condition than I would have thought.

That is why I am going to put much more focus, effort, and energy on also figuring out how to possibly repair articular cartilage damage than before. I am not saying that I am going to figure out the next best thing to treat osteo-arthritis or tissue inflammation but I understand that what I have been researching non-stop for the last 2 year can be very helpful in my own personal life, and to the people around me who I care about.

This desire to help people become taller and gain height even after skeletal maturity will always be there, with a focus on the scientific research. I also now understand that what I have uncovered can also be used to treat much more severe medical conditions.

If I have the chance to help someone out with a medical condition with the deep insight that I gained from thousands of hours of reading, then I would do that.

Second Issue

Most of the people who have regularly visited the website might have noticed that over time, it has slowly changed in form, and become more technical. Some of it might get harder to understand and read. That is something that I knew would happen. The level of medical understanding needs to improve over time (as well as the quality of writing).

With a much more sophisticated understanding of the overall human body, I would finally be able to understand the research that the world’s top experts are working on. If I can, I want to synthesize the results that they have found to discover something completely new.

A recent search on Google lead me to this question posed in the USMLE Step 1 Exam and it showed me that there is still much more I need to learn and understand before I can ever make a clear and logical argument on our theories before any professional orthopedic specialist.
Embryonic Chondrogenesis

It seems that my understanding of at least the process of Mesenchymal Stem Cell Condensation during embryogenesis to form the Chondrocytes is still lacking on how the protein signal pathways work.

I asked the question later whether the chemical compound Dibutyryl cAMP can be used as a way to get the MSCs in our own blood marrow to go directly into the chondrogenic lineage like they seem to do during the embryogenic process. It would turn out that I was wrong about this issue. Dibutyryl cAMP is a very unique compound which is only expressed/found in chondrocytes. It seems to be a type of chemical indicator used by researchers to check to make sure that what a cell differentiated into is indeed actually chondrocytes.

Do Shorter Men Or Taller Men Make Better Husbands?

Do Shorter Men Or Taller Men Make Better Husbands?

Shorter Men(Picture to the right is taken from here.)

This subject seems to have developed recently due to the fact that two article recently came out which referenced a study and they gave almost exactly the opposite, contradicting information and viewpoint.

The people at the reddit/r/short sub threads were upset that there didn’t seem to be a really clear answer. They referenced this problem Here. Well, it turns out the article “Short Men Make Better Boyfriends and Husbands” was WRONG. The writer of that article interpreted the discussion section incorrectly. The two articles which have gone viral seem to contradict their points, and one of them is indeed wrong.

Refer to the study available here. Note that it is not a hundred page Masters or Ph.D Thesis but just a 20 page working paper which is not fully finished.

Here is what the paper actually says, after I took a look at the discussion section. I will outline each point that the authors were trying to make, very clearly.

Point #1 – The qualities of short, average, and tall men’s spouses are not the same.

Point #2 – The taller men are more likely to mate with a women who finished high school than the shorter men. (Personally, this doesn’t say a lot). The author then takes this data and give her own interpretation of it, which she thinks means that the “better educated” females are willing to mate with the taller guys by sort of doing a type of value exchange. (Personally, I don’t think being able to graduate from high school should be considered “better educated”)

Point #3 – The the tallest men appear to be more likely to couple with older women, while shorter men most of the time couple with younger women. – (The author interprets this to suggest that a taller guy would look older relative to the shorter guy, so that older women thinks he is more to their age)

Point #4 – Since it was found that shorter men seem to couple with younger women more often than not, it causes and/or contributes to the fact that those relationships where there is a shorter guy, the relationship is more traditional, where the guy is the breadwinner.

As the author explains… ” This further underscores how height, and more generally men’s
attractiveness, affects other types of status exchange and indirectly contributes to the exchange of resources within a union

My Interpretation: It seems to mean that when the guy is lacking in height (which is a attribute most humans value) , he needs to use a another way to signify that he has value and he can give some type of value towards the relationship/union/coupling.

Point #5 – Shorter men are more likely to end up in relationships where they are shorter or at the same height as their partner (Duh!!! No shit sherlock). The relationships are rare, being only about 9% of the relationships.

Point #6 – By choosing a more traditional type of relationship where the man makes much more money than the women and does less housework, “…it allows short men to enact traditional gender ideals,  thereby performing their masculinity in the absence of expected anthropomorphic differences

Point #7 – Shorter men tend to be in more stable relationships than average and tall men.

Point #8 – Shorter men marry at lower rates and get married later in life (aka get into the relationship later than their taller counterparts)

Point #9 – The reason why shorter men get married later is because “...is reflective of a selection process in which some women opt out of a marriage with short men before it begins” – (Aka they get rejected by women much more in the get go. It takes the shorter men much longer for them to find a women who accepts them as a suitable marriage partner.)

Conclusions

So is the taller or shorter men better husbands?

The shorter men do get married later in life, but the long term relationships (aka marriages) that they do get into are much more stable. That is because they seem to specifically look to get into relationships where they are the one who earns the main amount of money in the household, thus a sort of traditional type of relationship. However, that also means that taller men do more housework than shorter men. It might suggest that taller men don’t mind switching the roles, and take a more non-traditional role.

It just comes down to the word “better”. If a better husband is one who does more housework, then it would be the taller one. If being a better husband means taking a bigger role in making the money for the household, then it would be the shorter ones. What I am certain is that the shorter men probably more often than not put much more commitment, energy and effort into a relationship than the taller counterparts. Even if they are NOT as likely be willing to help out around the house as their taller counterparts, they are putting their energy into making money for the house.

The fact is that as long as you make enough money, you can afford to hire a maid & nanny to do all that house work for you. You just have to focus on making money for cash flow.

So it is just a sort of insecurity issue, where taller men don’t feel particularly insecure about their position in the relationship or being thought of as being too feminine for being willing to do more housework and take care of the kids?

I don’t know. However, That would definitely explain why in the Northern European aka Scandanavian countries like Sweden, Denmark, and Norway , which are very egalitarian, the men are now becoming more like stay-at-home-dads. That phenomena has been well documented and even shown on an episode of the TV Show Welcome to Sweden, which was talked about on the reddit/r/tall sub threads, which is quite interesting. 

So here is everything wrapped up…

Main Thesis: Relatively speaking, when comparing the overall percentages of couplings/relationships, the taller men actually do more housework at home than the shorter men, because shorter men tend to choose women who are younger than them (than the taller men) and look to get into the more traditional/non-egalitarian type of relationship, as a way to compensate for their lack of anthropometric value, which sort of suggests that the short guy’s way of expressing his masculinity is by being the breadwinner and giving financial value.

That is what the study actually says. It is NOT my personal thoughts, but the exact meaning of what the author says.

Epilogue

I don’t know for sure whether it is absolutely true that shorter men at some unconscious level is trying to compensate for their lack of value from body size by looking for women who are younger and want to get into that traditional relationship to maybe prove their masculinity by making more money relatively than the women.

The truth is that we could flip the entire thesis around and still be able to come with a half-assed reasonable explanation (aka justification and rationalization) why taller men get into more stable relationships and shorter men do more household work.

That PDF that someone else linked to is for the Sociology Department at NYU. Sociology maybe be categorized as a type of social science, but it is not true “hard” science, where everything is measured and there is a true logic to everything.

The social sciences (which I call the “soft” sciences) are looking at human behavior and how cultures behave, and as we all know, the study of human behavior is not an exact science. Humans are not completely logical computer programs or robots. We are irrational, and no economist or economical theory will ever be able to explain the dozens, maybe even hundreds of psychological factors, desires, needs, beliefs, and values that we have. Traditionally the entire study of economics was based on one fundamental principal, which is that humans will always act accordingly and rationally based on their individual selfish needs and desires. That was proven wrong, since sometimes we do things that go against that principle. We are irrational, and our actions can not be predicted 100% of the time, although some theories developed can predict what the majority of the people will do for the majority of the time.

We are a truly very complex species, with often contradictory emotions and thoughts going on in our heads. We will say one thing and do another thing. We can be the most kind of people but also turn into savages with a simple nudge.

(Side Thoughts: It is said that India is supposed to be the land of contradictions, but people also say that about China too. Then there are people who say that Japan is a land of contradictions. Others say that about Dubai of the UAE. So which country is not a country of contradictions? – When economists describe these two billion plus countries, both of the countries are described the same way, by saying that the nation is one of contradictions. They want to push towards the future and make progress and growth, but you also want to preserve the old traditions and values. If one writer says that “India is a land of contradictions” and another writer says that  “China is a land of contradictions” and another writer says that “Japan is a nation of contradictions“, and another says that “Dubai is a city of contradictions” then you realize that there is not going to be some simple and easy rule to label any group of people, especially the countries with over a billion people. We are all living in the gray area, where we can’t be defined through the prism of black and white, 1s and 0s.)

There is too much room for interpretation and re-interpretation, even when there is hard numbers and data analysis using trend lines and monte carlo statistical simulations. When we try to make our interpretation of data gathers from polls, surveys, anecdotal stories, individual personal experiences, unique references, etc. aka the entire gammit of human behavior, we often are not completely objective and throw our own biases into it.

For almost the exact same conclusion I just reached, refer to the Huffington Post article “New Study Reveals Interesting Link Between Men’s Height And Divorce

What I Learned From Attending The Annual 3D Printer World Expo

What I Learned From Attending The Annual 3D Printer World Expo

3D Printer World ExpoSince the annual 3D Printer World Expo was being held this year at Seattle, (more specifically Bellevue, WA) I bought tickets to attend the expo and listen to the speakers talk about the revolution that is taking place right at this time, which will revolutionize the world in the coming decades to come.

The event was being held from August 22-23, 2014 which concluded tonight. I decided only to attend the conference the first day, and talk with all of the people at the exhibits to see how far they have come along in being able to develop products for medical application.

There was three main reasons why I decided to attend.

First, I realize that the revolution of 3D Printers is going to bring about a paradigm shift in the form of a disruptive technology, similar to how the company Uber is trying to transform the taxi service industry. It is absolutely critical to keep up with the real edge of what is going on in the world today. At the expo, I was able to try out the Oculus Rift that people in the tech world have all been going crazy for, with the people from Prizmiq.

Second, I wanted to see who is already trying to create biocompatible implantable hyaline cartilage, by combining the fields of tissue engineering and stem cells, for what I believe will be the real revolution for our endeavor.

Third, I have started to go into research on the developing technology of turning humans into androids/cyborgs. I have already jumped on the BioHacking bandwagon, promoting the idea set forth by David Asprey, but I feel like there is much further we can go to integrate the electronic world with the biological world.

I took pictures, got free stuff, and talked to people who are in the industry who are promoting their businesses and products.

For our purposes though, I asked each of companies that was selling or promoting 3D Printers the question, “Are you guys selling 3D Printers that has the ability to print bio-compatible, in vivo implantable functional human cartilage?

Almost all of the companies I talked to said no, except maybe 1 company (Nytec). When I asked just how fine the filaments threads can get to in terms of accuracy in making these 3D Models, the smallest I found was around 7-8 microns, with the upper end being around 200 microns.

Here is some things which they did tell me which is being created.

PEEK BIo-Material (poly-ether-ether-ketone) – Unlike the PLA and the ABS type plastic extruded filament material that is traditionally used to make 3D models, there is a another material that is coming out known as PEEK Material. It has been used apparently for the last decade and has slowly had multiple variations/derivatives of the PEEK material made. Its various materials characteristics makes it the most attractive material to be used for in vivo implants. (Refer to study “PEEK Biomaterials in Trauma, Orthopedic, and Spinal Implants” or “In vivo biocompatibility testing of peek polymer for a spinal implant system: A study in rabbits“)

Organovo – This company I have done research before, and it seems like they are the main company to focus on. The people who organized the 3D World Expo when I asked them specifically named this company for 3D Printing Implantable Tissues. I originally referred to Organovo when I wrote about the possibility of using the biomedical practice of Bioprinting aka Electrospinning in the post “Increase Height And Grow Taller Through Bioprinting And Electrospinning“. On the company website, they state the following…

“…Our 3D bioprinted human tissues are constructed with precision from tiny building blocks made of living human cells, using a process that translates tissue-specific geometries and cellular components into 3D designs that can be executed by an Organovo NovoGen Bioprinter. Once built, the bioprinted tissues share many key features with native tissue, including tissue-like cellular density, presence of multiple cell types, and the development of key architectural and functional features associated with the target native tissue.”

RegenovoRegenovo – This seems to to be China’s answer to Organovo. From the 3DPrintersIndustry.com website, they say that the China based Regenovo is still about 15 years away from being available to the average patient. It is a type of”…medical grade 3D bioprinters that is still under development and showing promising results“. The researchers at Regenovo have already been able to bioprint out a fibrocartilage based ear type tissue, as well as potentially also noses.

Since Regenovo is already able to print out nose and ear structures in about 1 hour!!, they should be able to re-create the chondrocyte column like structure that is found in the epiphyseal hyaline cartilage which can be a mass-produced synthetic growth plate which can be popped into a bone resection to lengthen the bone. The researchers are from some university in Hangzhou and are working with Independent Intellectual Property Rights (IIPRs). The developer named Xu Ming-en is able to create a 4-5 inch wide ear cartilage part within 1 hour already using the regenovo 3d bioprinter.

From the website 3DPrinterWorld.com website, what we are seeing is that along with Organovo & Regenovo, there are labs in Universities around the world like Wake Forest, Cornell, and the University of Iowa who are all working on very similar areas of focus, aka cartilage and spinal disc regeneration.

Taulman3D.com – This company supposedly got a FDA approval also a day ago for using their implantable nylon based material for medical applications.

Selective Laser Sintering (aka SLS) – This is a type of way of 3D Printing method based on using a laser to add more material on the object you are trying to shape and form. Currently, I know very little about this type of manufacturing technique, although it seems to be one of the manufacturing industries most common approaches to making parts.

One company I talked to say that SLS might be able to be used to make implantable parts. I forgot which one though by now.

However, what I have noticed is that due to the nature of the filament (aka raw materials) you are heating up and extruding through the extruder head, these materials like the most two types of filament material, PLA and ABS just can’t be used for medical application, since they would poison the person who tried to put the thermoplastic either in their body or on their skin. Now, there are many, MANY, companies right now who are using 3D Printers to build and make prosthetics, (like for instance Coyote Design & Mfg based in Idaho) by making bone like-tissue which will be placed along the skin but very few companies have been able to succeed in printing things that would work okay inside the human body.

Here is something I didn’t realize maybe months ago when I was writing about the possibility of using 3D Printers to print out our own internal organs. Currently, there is maybe about just 2 dozen types of materials that you can use as the raw material in the filament to make the models and shapes that you want. Here are some of the most common types…

  • ABS
  • HIPS
  • PLA
  • NYLON
  • PVA
  • TPE
  • T-GLASE

What to take away from it all… 

I have been trying to combine all of the areas/fields that I am interested in and doing research on into one. So far, that has led me into the field of 3D Printers and finding the right type of collagen/scaffold configuration to create new cartilage tissue.

It has already been shown by at least 2 sources that making a 10 cm wide piece of fibrocartilage layer is already possible, taking just around 1 hour. I am wondering just how hard would it be to turn that ear/nose piece already made in multiple university labs around the world into hyaline cartilage and make the type of functional implantable cartilage that can expand and make our bones grow volumetrically. Not too hard I suppose.

If the researchers really wanted to, they would be able to get the new growth implant implantations available for the general public’s use within maybe just 3-5 years if they actually put all their effort and focus into it.

To end this post, I give you a vision of what will almost definitely come about in the future, with the forward being presented by former Lucasian Professor of Cambridge, Dr. Stephen Hawking, on how medical breakthroughs have allowed him to live and function beyond the years expected of him when he was first diagnosed with Lou Gehrig’s Disease decades ago.
