Neurosurgeons use adult stem cells to grow neck vertebrae. Neurosurgery researchers at UC Davis Health System have used a new, leading-edge stem cell therapy to promote the growth of bone tissue following the removal of cervical discs — the cushions between the bones in the neck — to relieve chronic, debilitating pain.The procedure was performed by associate professors of neurosurgery Kee Kim and Rudolph Schrot.
It used bone marrow-derived adult stem cells to promote the growth of the bone tissue essential for spinal fusion following surgery, as part of a nationwide, multicenter clinical trial of the therapy.Removal of the cervical disc relieves pain by eliminating friction between the vertebrae and/or nerve compression. Spinal fusion is used following surgery for degenerative disc disease, where the cusioning cartilage has worn away, leaving bone to rub agains bone and herniated discs, where the discs pinch or compress nerves.
New drug could cure nearly any viral infection. Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago.
However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers at MIT’s Lincoln Laboratory has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection.
The microscope images above show that DRACO successfully treats viral infections. In the left set of four photos, rhinovirus (the common cold virus) kills untreated human cells (lower left), whereas DRACO has no toxicity in uninfected cells (upper right) and cures an infected cell population (lower right).

'Super antibody' fights off flu. 29 July 2011Last updated at 08:49 By James Gallagher Health reporter, BBC News A jab protecting against all flu viruses is considered a holy grails of vaccine research The first antibody which can fight all types of the influenza A virus has been discovered, researchers claim.
Experiments on flu-infected mice, published in Science Express, showed the antibody could be used as an "emergency treatment". It is hoped the development will lead to a "universal vaccine" - currently a new jab has to be made for each winter as viruses change. Virologists described the finding as a "good step forward".

Special Report - An end to AIDS? By Kate Kelland LONDON (Reuters) - For his doctors, Timothy Ray Brown was a shot in the dark.
An HIV-positive American who was cured by a unique type of bone marrow transplant, the man known as "the Berlin patient" has become an icon of what scientists hope could be the next phase of the AIDS pandemic: its end. Dramatic scientific advances since HIV was first discovered 30 years ago this week mean the virus is no longer a death sentence. Thanks to tests that detect HIV early, new antiretroviral AIDS drugs that can control the virus for decades, and a range of ways to stop it being spread, 33.3 million people around the world are learning to live with HIV. People like Vuyiseka Dubula, an HIV-positive AIDS activist and mother in Cape Town, South Africa, can expect relatively normal, full lives. Experiment aboard shuttle Atlantis will test novel therapy to build bone during space travel.

Drug makes hearts repair themselves. 8 June 2011Last updated at 18:00 By James Gallagher Health reporter, BBC News More people are surviving heart attacks, but that means more are living with heart failure A drug that makes hearts repair themselves has been used in research on mice.
The damage caused by a heart attack had previously been considered permanent. But a study in the journal Nature showed the drug, thymosin beta 4, if used in advance of a heart attack, was able to "prime" the heart for repair. The British Heart Foundation described repair as the "holy grail of heart research", but said any treatment in humans was years away. Due to advances in health care the number of people dying from coronary heart disease is falling. Electromagnetic radiation and the brain 5 of 5. Cell phones and Brain Cancer.

3D Human Anatomy. Stem cells coaxed into forming partial eyeball - life - 06 April 2011. Mouse stem cells have been coaxed into forming a partial eyeball, and the method may one day lead to retina transplants.
Yoshiki Sasai at the RIKEN Center for Developmental Biology in Kobe, Japan, and colleagues encouraged embryonic stem cells to develop into retinal cells, and then grew them alongside a protein matrix to promote the formation of tissue. Over 12 days, the retinal cells formed a vesicle which subsequently transformed into a cup-like structure. Within this "optic cup", six major types of retinal cells were identified.
