In this case I'm beyond sceptical. Stem cells are often given to medical tourists as the very words conjure up the idea of miracle cures in peoples minds, when there really is no evidence to think it will be of any clinical benefit (and in fact there is often evidence that it will be harmful).
If we were at the stage in medical science where we could cure chronic renal failure by using stem cells we would have done so in rats, or some other model animal, already - and we haven't yet to my knowledge.
It is likely that the theam that is going to administer the stem cells has no idea of how proper research is conducted, no idea of the basic science of stem cell therapy and no concept of ethics.
For instance, I heard of a case some time ago in which a young child was taken to South America for stem cell treatment after many years of being in a near vegetative state following some sort of damage to his brain. The "scientists" and "doctors", at the clinical promised massive improvement, and every time they flew over to go to the clinic a brain scan would be done - and improvement would be proclaimed. Back in their native USA, however, one of the doctors that had been involved in the childs long term care convinced the family to have a scan done at home - and it was painfully obvious to anyone with any medical knowledge that the therapy had in fact caused massive irrepairable brain damage.
Stem cells aren't a valid experimental treatment for most conditions (if they were, they would actually be offered in first world patients) they are simply a scam.
I'll attend, cool :)
The peanut is an interesting example. I think projects are underway to produce modified varieties that lack the allergens which people tend to react to.
Yeah but remember, there will always be a limit to the price they can charge for the GMO - and that will be determined by the cost of the wild type and the productivity different between the two. Thus Mosanto will only be able to sell it if it is worthwile for the farmers! Also, patents do expire eventually.
Lol, I'm still pretty sure it would be bad to put genes in to produce more of them though.
I am sorry but I have yet to hear of a GMO project that involved removing micronutrients! The only ones I've heard of have involved adding things, e.g. adding vitamin A to rice, adding virus compounds to potatos to act as a vaccine, adding resistance to parasites and viruses etc. Never, ever ever ever heard of a project to remove something.
Your final paragraph isn't really relevant, I mean look at golden rice for instance.
GMOs can be safe, they can be unsafe. For instance, if you inserted a gene into a potato to produce poisonous cyanide compounds that would be unsafe. Engineering a rice variety to produce Vitamin A precursors, however, is not likely to be unsafe on a basic scientific level and once the crop has been tested and retested for toxicity and other concerns it is simply not plausible that it would be dangerous.
Other intentions of GMOs can be, for instance, to produce an organism which is naturally resistant to pests or which is better able to grow in a variety of climates. With regards to pest resistance the toxicity of the compound would, of course, have to be tested first - but artificial pesticides are regularly sprayed on crops anyway so I do not see how it is different.
With regards to increased proliferation or better adaptation to more climates, the fear that they will somehow destroy the ecosystem is quite unfounded - if a plant which was slightly better adapted could do this evolution would have assured mutual destruction by know already. Remember that modern varieties of crop plants are probably not well suited to growth outside of human cultivation, being bread to human needs which may be maladaptive in the wild. GMOs are no more capable of taking over the world than their wild type counterparts I assure you - we are years and years away from being able to design something so effectively!
Look at what the basic science of genetic modification is - inserting a known gene or known series of genes into an organisms code under the control of specific gene switches in order to get a desired phenotype. Its not that scary really, an additional gene or an additional few genes added to what is no doubt already thousands. It is merely an accelerated and highly specific form of artificial selection which has been going on for centuries. The exact function of the genes being inserted will no doubt have been ascertained precisely before getting anywhere near the stage of producing a GMO. The only potential risk I can think of is unexpected interactions between metabolites in other biochemical pathways - but this would be picked up on pre release testing and possibly even in silico modelling, and thus can be easily managed.
The fear over GMOs is quite out of control, for instance I have in the past worked with GMOs in a lab setting. This were genetically modified fruit flies (which had the reporter gene Lac-Z added next to genes of interest in order to permit visualisation of gene expression) and Chinese hamster ovary cells which had the cannabinoid receptor artificially added to their repertoire. With both the control were laughably excessive, the fruit flies are no different than their wild type counterparts in terms of any threat of danger and the CHO cells like to die even when good care is taken of them in highly controlled conditions (trust me, they wouldn't last a day if they got out of the lab). Yet still, we had to put up with the highest level restrictions and procedures when working with these in order to absolutely rule out environmental contamination - including intrusive inspections by government staff.
Um... what so you'd rather have diagnoses that are not based upon data? Or a diagnosis which is made up versus no diagnosis? I don't quite understand what you mean. Illnesses in the human body cannot be solved in the same way as an engineering problem, particularly at the margins. Most of the medical knowledge that could be derived without careful and large clinical trials is already known - I'm not sure what you expect a single doctor to do.
Furthermore, note that most patients will not die undiagnosed - bar situations, such as in geriatric patients, where many things are so suboptimal that you just can't sort out what is killing them and what is just background noise. It is very rare that "creative debugging" would be of any use at all.
Secondly, many patients in a terminal situation often what more medicine. They feel that not treating with aggressive chemotherapy or some such treatment is giving up. This is not always the case, it is often in terminal illnesses that palliative care is the best option and avoiding aggressive treatment will in fact lead to a longer life. No amount of debugging will change that.
Let me stress once again that it is not often a patient will die where a diagnosis has not been achieved where the correct diagnosis would have materially changed the outcome.
It is likely going to be a net negative for society as I doubt that any information of value can be derived from this sort of experiment in humans. There is still a lot of animal research that has to be done before human trials can bring anything useful to the table. To my knowledge, chronic renal failure isn't even close to being treatable usign stem cells in rats or any other model animal.
It is likely that the team of "scientists" in this case are a bunch of phonies with know comprehension of the basic science behind stem cells, or any serious training in research.
