Re: Ask a Scientist

Well, you can take glucosamine tablets, and I have no idea what you mean by articulations.

Glucosamine is not something that you would normally be able to ingest in your daily diet. It is synthesized in the body. The commercially available glucosamine is obtained from chitin, a substance found in shrimp, crab, and lobster shells. However, if a person is allergic to any of those things they should not take glucosamine made from them.

The jury is still out whether or not taking glucosamine actually helps your joints. However, I had a Blue Heeler with really bad hips and a daily dose of glucosamine did wonders for his mobility. Also, I've had human friends who say it also worked for them.

Basically glucosamine is a sugar derived from glucose and has been shown (in a lab, I believe) to speed up production of both proteoglycans and collagen and it normalises cartilage metabolism which helps keep cartilage from breaking down. Basically those are all components that make up what connects your bones to one another.

Could it have to do with the fact that a significantly larger fraction (by orders of magnitude) of male population is (partially) color-blind?

I don't know how to post a vote, but we could check what percentage of EF males and females can see see the numbers in all the pictures in this article:

Re: Ask a Scientist

It appears that glucosamine works on a responder and non responder basis. To be honest I don't know the mechanism but you can maybe read a little further in the following links and find what you need.

Generally with supplements like Glucosamine tablets alot of what you read is based on marketing from the company that produces it, not scientific fact. After a quick search of clinical trials and randomised controlled trials I found these links.

Re: Ask a Scientist

Yeah, that's why I said the jury is still out. Too many of the studies are by the people who want to sell the product (that whole biased sciency thing). That being said, I have seen it help.

Do electric stimulus muscle toners really work ? I was watching an infomercial last night and pulsing spasms of the models buns was almost hypnotic...

They actually look quite painful in use, and I cant believe anyone using the device can read a book while twitching like a sealion that hugh has just battered.

Anyone going to own-up to having bought/used one with any success ?

dave


PS: Just for the record, no , I am not considering buying one.
I love them. I had a long discussion about them with a physiotherapist on a plane trip, They're really good for a massage like feeling or to get back after injury. It's very weird to watch though, try putting them on your belly, the muscles almost volcano up- reminded me of alien. It also helped me to identify/isolate certain muscles and know how it should feel when they contract. They did leave me breathless the first time on the belly, but that may have been the shock of experiencing what they can do!
I almost bought one on line, but was advised to stick to regular exercise. I'd still like to buy one but professional ones are expensive

I assume you mean "bang" as in a sound. Sound needs a medium to be transmitted. The entire universe consisted of plasma, which I guess counts as a medium. Of course at a couple of million degrees it would pretty much destroy anything there to witness it. If a tree falls in a forest....

If a tree falls in the woods and there is no one there to see it does it still make a sound?

Thanks for your answer !

articulation (r-tĭk'yə-lā'shən)
Anatomy.
  1. A fixed or movable joint between bones.
  2. A movable joint between inflexible parts of the body of an animal, as the divisions of an appendage in arthropods.

I agree with Chemgoddess- the jury is still out. Also the problem with a lot of supplements is that they are unregulated in many countries, so you can't be sure what's in them. I used to have a very strange diet- no fats only nut oil and was over-exercising, I could actually feel my body creaking, especailly my spine, so I started taking MSM, chrondoitin and Glucosamine, it didn't help and then found out it was derived from animal products- beef etc. I reintroduced oils- olive, fish oil, Q10, DHEA (questionable) Alphalipoic acid ( stinks) and antooxidants and felt much better. I think that it was the olive oil that made the difference.

Re: Ask a Scientist

Thanks Verena

I think this is actually the problem. I eat very few oils and grease and do a lot of sports ( that involve a lot of running that I didn't do before as I have been a cyclist for years), and my articulations ( joints ) are hurting.

I started taking Glucosamin in Tablets to help it, but I think the best thing would be start eating more grease ( yuk )

Re: Ask a Scientist

Very good point. Before taking a supplement it is a very good idea to figure out how the company obtains their ingrediants, particularly if you have food allergies. As the animal derived glucosamine didn't work, if you wanted to give 'er another go you might want to try one that is obtained from a purer source of glucosamine.

And neither you nor Salsa_Lover should forget that fatty acids and good fats are an essential part of a healthy diet for optimal body function. It doesn't need to be bacon grease, but put some olive oil on your salad.

Re: Ask a Scientist

I was at a conference a few years back where supplements and their purity was one speakers presentation. He showed a table of the main countries which produce dietary supplements and the purity levels of samples of produce which came from these countries. One of the things that stuck out to me at the time was that the products that were produced in Switzerland were very high quality, and in the cases presented far above the quality of those produced in the US of A.

Sorry I can't remember the specifics of the presentation.

While working at Volketswil kids centre the swiss equivalent to the FDA shut down a little store supplying US groceries because of the additives.
Recently in Switzerland my skin allergies cleared up, I felt much better. I returned to the US the alerfies came back. I started filtering the water and studying food labels very carefully.

Re: Ask a Scientist

Here's a doom and gloom question- How do the US protect their warhead on the gulf carriers from attack. Is it possible that a missile could hit one and set it off? Or that the carrier gets hit, explodes and that sets it off- is that possible?

Re: Ask a Scientist

Right as I said before not omniscient.

I don't want to be a pissy-pants, I'm trying to keep this thread as sciencey-based as possible and would rather it not turn into downward spiral regarding nuclear warheads and missile attacks.

Sorry.

As far as the allergies and skin problems in the US, I would speculate that it might have something to do with all the high fructose corn syrup that seems to be in everything in the US.

Do some people see a wider colour spectrum than others ?
Well, there is another angle you can take on this. One of the great debates in Psychology is whether language influences thinking (linguistic relativity theory) or vice versa. Apparently, people whose language does not have a broad vocabulary for colours find it more difficult to differentiate between different shades, at least according to studies conducted by the linguistic relativists.

This may also explain why men have more trouble with colours, as girls are usually taught more terms relating to colour than boys are. Send a man out to get something mauve-coloured or in a shade of ochre and you may be in for some interesting results.

Re: Ask a Scientist

Huh. Interesting theory. Never really thought about it that way.

Although I'm not sure if you sent me out for something in a shade of ochre I'd know what I was looking for either.

I totally know mauve though

Wikipedia reference-linkMauve

Geez, who know there were so many permutations to mauve. Light mauve, opera mauve, taupe mauve. No wonder the guys are confused.

Re: Ask a Scientist

Thanks, Kittster, for an interesting answer, even though it wasn't strictly scientific. What I was getting at was, if some people can actually see colours beyond the spectrum that is generally known to be visible. Can some see some shades of ultraviolet or infra-red that others can't ?

Men like to keep things simple, there's no need to describe things in complicated terms when red , green, blue and yellow are adequate. For compliicated beings like a woman there are probably a thousand shades of mauve, and somehow a man is expected to know exactly the one they like best, or matches their shoes. (sigh)

Re: Ask a Scientist

In Switzerland (or rather, in Swiss school art classes), ochre (Ocker) is sort of dusty, dark shade between beige and yellow, in the internet it's a light, reddish shade of brown. Which is another difficulty in colours, your lilac may be my lavender.

I was lucky enough to have a lovely box of 80 Caran d'Ache Prismalo Colour Pencils, whereby each of them has it's own number and the number has the corresponding name written on the back of the box. Yes, I was a boring kid. But I sure know my colours.
