Medical advances hold promise for less-destructive cancer treatment by way of genetic m... - 0 views

  •  
    If a mutation occurs in a person's genes it can cause cancer. The future of cancer therapy is identifying and targeting these mutations. A trial at the University of Florida, known as NSCABP-FC-7 takes the genetic fingerprint of a patients DNA and gives them a personalized treatment based on the information. The idea is to move away from the traditional cytotoxic treatment, and towards less toxic personalized medicine. However, the toxicity of cancer drugs is decreasing due to technology's increasing ability to target and destroy specific cells, and not healthy cells. Washington University St. Louis as well as other institutions have become part of the study. Overall, the future of cancer treatment lies in targeted therapies and personalized medicine.

Retina stem cell transplants restore sight to blind mice: study - NY Daily News - 0 views

  •  
    British scientists have recently restored sight to blind mice by the use of stem cells from mice embryos. These stem cells were put into a lab dish; there, they separated into immature photo-receptors. These were then injected into the mice's retinas, and actually brought sight back into some of the blind. This successful experiment makes scientists hopeful that they can restore sight to blind humans in the future. Although these cells can become very beneficial, they can also turn cancerous. New scientific advancements have bettered the stem cell procedure, but problems with the process are still arising.

    When Connie Culp was shot in the face by her husband she was given the opportunity to undergo a face transplant. The chairman of the surgery Jeffery Mathews states that the is the most dramatic technological advances ever. To complete the surgery they have to attach the small muscles veins and nerves between the patient and the donors face. To make sure the patient doesn't reject the transplant they have to infuse special marrow cells and immune suppressing drugs.

How sweet it is: Bioenergy advanced by new tool -- ScienceDaily - 0 views

  •  
    Researchers have created an assay that can analyze nucleotide sugar transporter functions in plants and characterize them. This assay can provide information that is very beneficial to the genetic engineering of plants. The information learned from the assay has already been used to change plants' biomass sugar composition. This sugar can be a very effective source of energy. The more sugar content the cell walls have, the more energy the plant will be able to provide.

Cooled Organs Stretch Transplant Time - 0 views

  •  
    In the article "Super Cooled Organs Could Stretch Time To Transplant" the author discusses how scientists have started an experiment to stretch out the shelf life of a harvested organ. The experiment was performed on rats, and in order to perform the experiment the scientists first harvested organs and essentially froze them, then the organs were sprayed with a variety of chemicals to keep the organ from developing ice crystals as well as to keep the organ functional. Then, after 3-4 days the organs were "defrosted" and transplanted to rats. The result was that that rats that received 3 day old organs (livers) lived for about 3 months and rats who received 4 day old livers had a 60% survival rate; whereas, rats who were given 3/4 day old livers preserved by modern day techniques all died. Which shows that the organ freezing method could potentially advance the duration for which an organ can be kept functional after being removed from a body which could drastically change the field of organ transplants.
