Harvey Has Partial Tear Tommy John Surgery Not Ruled Out - RealGM Wiretap
Matt Harvey has been diagnosed with a partially torn ulnar collateral ligament in his pitching elbow and has been placed on the disabled list.
Surgery has not been ruled out and if Tommy John surgery is required Womens Deion Sanders Jersey , he could miss the entire 2014 season.
Harvey was sent to a doctor after complaining of fatigue and mentioning discomfort following a 102-pitch start Saturday.
Harvey has swelling, but had not been experiencing pain in the elbow before his last start.
锘? Stem cells could be the beginning of the end for deadly diseases, by allowing medical science to form custom-made tissues and organs that would replace or repair damaged ones.
Scientists haven't yet mastered the process of creating specialized cells that form body parts. But they have come a long way since the 1800s when pathologist Rudolf Virchow pioneered the idea that disease starts at the cellular level in his Berlin laboratory.
Embryonic stem cell research got its start in the U.S. in November 1998 when James Thomson, a scientist at the University of Wisconsin in Madison, was the first to successfully remove cells from spare embryos at fertility clinics. He established the world's first human embryonic stem cell line. His announcement however, set off a firestorm of controversy that was quickly carried into countries around the world.
At the center of the controversy was a wave of political and religious fervor, with zealots who likened the research to cannibalism, and warned of a dark Womens Carlos Hyde Jersey , science fiction-like future filled with "embryo farms" and "cloning mills"
In truth, every year thousands of unwanted embryos are slated for disposal at fertility clinics around the country. These embryos are smaller than the dot above the letter "i" when typed onto a piece of paper.
They have no identifying features, and not even a hint of a nervous system.
To throw them away, advocates say, when the stem cells themselves would be unable to develop into a baby - even if planted inside a uterus - seems an unthinkable waste that they claim borders on immoral.
Some forms of stem cell therapy have been around - and widely used - for decades. For example, bone marrow transplants are used to treat sickle cell anemia. The stem cells in the donated bone marrow regenerate the patient's blood and immune system.
It works like this - one cell divides, and becomes two. The two become four. And so on and so on, until they multiply into a ball of millions of cells. Similar cells combine into tissues Womens NaVorro Bowman Jersey , and the tissues combine into organs. There are over 200 different types of cells that create the human body. And inside each of us are billions of cells, each with a specific job to do.
A stem cell is a cell that matures and has the ability to self-replicate - often throughout the life of the organism. So, the dream for medical researchers is to provide the right conditions - or give specific stems cells the right signals - so that a targeted stem cell will develop into mature cells that could repair diseased tissues or organs. If successful, it would mean the end of crude mechanical devices such as insulin pumps, titanium joints or plastic arteries, and use living, natural replacements.
The potential for stem cell medicine is awe inspiring. Stem cell lines could be used to help burn victims, and those who have suffered spinal cord injuries. It also has the potential to cure many common diseases of today Elite Steve Young Jersey , such as diabetes, heart disease and some types of cancer.
Even in the midst of all the controversy, few question the medical promise of embryonic stem cells.
And while the arguments go back and forth, policymakers and governments aren't waiting for medical answers.
Their reactions - and actions - that have included limiting government funding and the type of research that is allowed are varied.
Germany for example has banned some types of stem cell research. Under President George W. Bush, the U.S. has imposed stern limits on the government funding, but left private funding wide open.
This has meant that the U.K., China, Korea and Singapore are competing with one another to become the epicenter of stem cell research. In addition to providing funding Elite Ronnie Lott Jersey , they've set up ethical oversights to encourage and support research in the field, within carefully drawn guidelines.
Despite the varied political climates, scientists too are working furiously to see which techniques will produce viable treatments the fastest.
In the United Kingdom, scientists are allowed to extract stem cells from embryos left over from in-vitro fertilizations, and to clone embryos specifically for study.
With an eye on the future, the U.K. has built the world's first Stem Cell bank. It is a repository where stem cell lines are kept in cold storage. Researchers can deposit and withdraw both adult and embryonic stem cells. They apply the same rigorous standards to all cells, and scientists hope that eventually they will be able to create batches of stem cells that are as uniform as the drugs created by pharmaceutical companies.
What are embryonic stem cells?
Most embryonic stem cells used in research come from embryos created in in-vitro fertilization.
Each embryo's inner cell mass has 40 or so stem cells. The mass is transferred to a culture dish lined with feeder cells. As the cells divide and multiply, they are re-planted into fresh culture dishes. If Elite Patrick Willis Jersey , after many months, the original stem cells have grown into millions of healthy cells without maturing and differentiating into specialized cells, they are referred to as a "stem cell line" and are capable of reproducing indefinitely.
