This week it is your turn to find a current event related to our current unit - cells. Find a news article related cells, organelles, or DNA. Write the name of the article and the author in your post. Paste the link into your comment. And then describe the article and how it relates to what you have learned in this unit.
Here are some sources that you can use to find articles:

http://www.popsci.com/science/article/2010-06/dna-database-help-prevent-dogfighting
ReplyDeleteThe article I found is called National Forensic Canine DNA Database to Help Combat Dogfighting. It was written by Rebecca Boyle from Popular Science. It talks about a new way dog-fighting rings can be shut down: by using DNA. Scientists recently created a database called Canine Combined DNA Index System. It is the best canine-DNA database so far because there are more markers in it than usual. People investigating dog fighting will be able to use the database in several ways. One is when they find dog blood at a suspected location, they can test it against their database and see if the DNA matches with any in it. Then they can find what dog it is, and will be closer to catching the people who are in charge. They can also use DNA they find to figure out what new dogs are being used. This article relates to what we are learning because we are currently learning about DNA. The article explains ways scientist use DNA in the real world, instead of just studying it in a laboratory. It helps explain why learning about DNA is so important and useful.
Dr. Doris A. Taylor's research team made a scientific breakthrough when scientists where able to take a dead rat heart, and bring it back to life. Now, I know it may sound like something out of frankinstein, but really it's true!! The scientists washed away all dead cells, leaving being on structural tissue. Then they injected live heart cells from a baby rat into the heart, and an artificial circulatory system was devised. After the living cells reached maturity, the heart was transplanted into a live rat, to see if it would take. It did and over time the living rat built cells around the heart till eventually the heart began beating! Through this breakthrough scientist in the next ten years will be able to produce real organs and transplant them into humans. Think of the thousands of lives we could save!! This is related to what I am learning in class threw DNA, where one DNA strand can make a whole bunch of different cells.

the national cell culture center we know have national cell culture center as a scientis I a blog. all the cells, DNA of the people will be classified catalogued al preserved they keep secreted proteins al scale animals cells. son people think it is not a good idea became they do not weast everyone Dna cells catalogued
ReplyDeletecell reaserch is illegal. 3billion of california voters are invested. thew trail is a positive breakthoough. the show that promise of a stem cell. melopark is running the american patients. i like this artical because it have a lot of information the i diint now about .
ReplyDeleteUnderstand DNA Damage and Repair
ReplyDeleteEveryday people damage their DNA without even knowing. Things as harmless as soda pop and as lethal as radiation have been found to damage are bodies DNA. By doing so we put ourselves at risk for many serious health problems. Our cells become inhibited in producing what our bodies need and our bodies become challenged in re-growing healthy cells. And since are DNA affects future generations as well, were putting them at risk! Thankfully there are a few ways to hep ourselves which include consuming chlorella, enzyme-rich raw foods, cabbage and other cruciferous vegetables.

ReplyDeleteThe paper that I found is called " High Response Rates Seen In Phase-lll Trial of Chemotherapy, New Drug and Stem Cells In Myeloma". Myeloma is a malignant tumor of the bone marrow. This study showed that two treatments achieved a positive response. Four hundred and two patients were tested. 83% of patients saw a partial response. 90% saw a reduction in paraprotein. This ground-breaking study will change the standard of care with multiple myeloma.
My article is named "High Response Rates Seen in Phase lll Trial of Chemotherapy, New Drug and Stem Cell In Myeloma"
ReplyDeleteThis is the first study comparing two different approaches to treating Myeloma a tumor in the bone marrow. High doses of hemopoietic stem-cell support against regular chemotherapy. Out of 402 patients half were given chemo while the other half received the stem cell therapy. 52% of those receiving the stem cell therapy responded better than 25% of those receiving chemo. This was the first trial comparing the two treatments for Myeloma, and shows possibilities for stem-cell treatment for this condition.
my article is on the water droplet bouncing off a superhydrophobic nanotube array. Basicly what i know so far that it relates to our unit is that it is hydrophobix and is very close to the nonpolar inside the phospholipids. and since is also hydrophobic. the nanotube has many layers such as densly packed carbon layer and flexible subtrates. like nonpolar molecules it pushes the water away.
ReplyDeleteA redesigned version of CTC-Chip captures rare cells of circulating tumor cells.
ReplyDeleteCalled the HB Herringbone Chip it colects tumor cells that are flowing through the blood.
The HB chip can process greater amounts of blood increasing the ability to find rare CTC's.
Dr. Daniel Haber say's "The new technology is a powerful platform that will enable increasingly sophisticated analyses of metastasis and support clinical research targeting cancer therapies".
Stem Cell Therapies Today
ReplyDeletelearn.genetics.utah.edu/content/tech/stemcells/sctoday/
While most blood stem cells reside in the bone marrow, a small number reside in the bloodstream. The PBSC (Peripheral blood stem cells) can be used in research just like the bone marrow cells.
Using PBSC's is a less invasive way to obtain stem cells.
Stem cell therapy is used to replace abnormal cells which might become cancerous like in Leukemia. Replacing bad cells with good cells can lead to the continued production of good cells.
