  • Growing a complete, functioning brain is unfeasible, but there is real potential in growing functional neural tissue containing specific types of cells, for transplantation into the human brain.

      It may not be possible to regrow a complete brain but we may not have to. If medical science was able they could potentially regrow certain cells and parts of the brain that have degenerated that could prove to cure certain diseases like Alzheimers.

    A study is being done in Japan that has regrown a pituitary gland that is fully funtional when it was transplanted into mice. How soon will it be before it is done on humans? Or is it already being done?

    This is showing me that the type of stem cells that i have chosen to focus on are the only ones that have shown any results in curing these illnesses. Will science do a way with embryonic stem cells and gear their efforts toward adult stem cell research or continue to try and use embryonic stem cells?

  • The researchers injected stem cells from rats into the embryos of mice that had been genetically altered so they could not produce their own organs, creating mice that had rat organs.

      If they are able to do this with animals what about humans? Is this ethical and effective.
  • The scientists claim the rat stem cells grew in the niche left by the absent mouse pancreas and so almost any organ could be produced in this way.

  • If replicated using human stem cells, the technique could produce a way of treating diabetic patients by providing a way of replacing their pancreas
  • In reality researchers are not allowed to create human embryos that lack the ability to grow organs and so they hope to do the same using pigs.
  • They have, however, already managed to produce pigs that were able to generate human blood by injecting blood stem cells from humans into pig foetuses. He said: "For ethical reasons we cannot make an organ deficient human embryo and use it for blastocyst complementation. "So to make use of this system to generate human organs, we must use this technique using blastocysts of livestock animals such as pigs instead
  • Blastocyst complementation across species had never been tested before, but we have now shown that it can work."

    This is discussing about using other animals to grow organs inside of those other animals.

Electric cars may not be so green after all, says British study | The Australian - 0 views

  • An electric car owner would have to drive at least 129,000km before producing a net saving in CO2. Many electric cars will not travel that far in their lifetime because they typically have a range of less than 145km on a single charge and are unsuitable for long trips. Even those driven 160,000km would save only about a tonne of CO2 over their lifetimes.
  • The British study, which is the first analysis of the full lifetime emissions of electric cars covering manufacturing, driving and disposal, undermines the case for tackling climate change by the rapid introduction of electric cars.
  • Britain's roads to increase from a few hundred now to 1.7 million by 2020.

  • $66 million over the next year giving up to 8,600 buyers of electric cars a grant of $7700 towards the purchase price. Ministers are considering extending the scheme.
  • The study was commissioned by the Low Carbon Vehicle Partnership, which is jointly funded by the British government and the car industry. It found that a mid-size electric car would produce 23.1 tonnes of CO2 over its lifetime, compared with 24 tonnes for a similar petrol car.
  • Emissions from manufacturing electric cars are at least 50 per cent higher because batteries are made from materials such as lithium, copper and refined silicon, which require much energy to be processed.
  • CO2 from producing an electric car rises to 12.6 tonnes, compared with 5.6 tonnes for a petrol car

  • Grekos showed the successful engraftment of stem cells into damaged organs and subsequent regeneration of tissue.
  • Dr. Grekos also highlighted several case studies to illustrate his team's success with Adult Stem Cells. According to their findings, cardiac disease patients experience an average increase of 21% in ejection rates as well as measurable improvements in congestive heart failure class status, some in as little as one month post-treatment
  • Regenocyte Therapeutic is currently using Adult Stem Cells Therapy to treat Congestive Heart Failure, Cardiomyopathy, Peripheral Artery Disease, Coronary Artery Disease, Kidney Disease, Ischemic Heart Disease, Pulmonary diseases (COPD, Pulmonary Fibrosis, and Pulmonary Hypertension) and Early Senile Dementia. Patients can call 866-216-5710 or visit http://www.regenocyte.com for information or consultation.

      I may want to contact this number for my research. 
  • Therapeutic, addressed physicians from around the world with a presentation on patients treated with pre-engineered Adult Stem Cells. In the presentation,
  • "This is the logical next step in harnessing the regenerative power of stem cells. This will be the next phase in turning science into medicine
  • PET scans confirm that Adult Stem Cells have the ability to engraft themselves into areas damaged by myocardial infarction (heart attacks) and turn into viable new heart muscle.
  • "Three months after treatment, cardiac nuclear scans of the areas treated reveal reversal of damage. We have been able to take patients off the transplant list, and we have been doing it consistently."
  • physicians at the Dominican Republic division of Regenocyte announced clinical results of a 46-year-old patient with pulmonary hypertension who was treated with Adult Stem Cells. His pulmonary artery mean pressure went from 41mmHg (severe pulmonary hypertension) to 24 mmHg (normal) in six months.
  • The patient's saturations are now consistently high and he no longer needs to be supplemented with oxygen continuously or considered for a lung transplant. Another patient was successfully treated for cardiac sequelae of Fabry's Disease, and is also no longer considered for heart transplant.

    A clinical essay on the use of stem cells on regrowing certain organs and its cit-effects. Is it more dangerous to use stem cells research? Does the benefits out weigh the risks of the procedures?
