Discovered a new molecule - the first of its kind that allows multiplication of stem cells from umbilical cord. This discovery is very important as these cells are used for transplantation for the treatment of blood diseases such as leukemia, lymphoma and myeloma.
 
The blood from the umbilical cord of the infant is considered an excellent source of hematopoietic stem cells that could be used for transplants.
 
These stem cells are less likely to cause an adverse reaction by the immunity in the recipient thereof to whom they are transplanted.
 
Furthermore, unlike the adult stem cells from bone marrow, it is not necessary, and the donor recipient has to have immunological compatibility for successful transplantation.
 
Such type of treatment, however, can not always lead to successful healing in adults, since the number of the collected stem cells from umbilical cord blood is small and insufficient. Scientists believe that by using the new molecule will be possible multiplication of stem cells to a sufficient quantity for the conduct of successful treatment.
 
Molecule is called the UM171 and was discovered by researchers from the Institute of Cancer Research and immunological and the University of Montreal, Canada.
 
Doctrine argue that UM171 has the potential to increase the number of blood units, ready for transplant to 10 times.

Macular degeneration is the leading cause of blindness worldwide. It affects one in five people 75 years of age.
 
The loss of vision is closely related to the aging process. The infringement is not seen so much as an actual condition, but rather as an inevitable part of aging.
 
New discovery by scientists from the UK, however, may soon change this data.
 
Researchers from the University of Southampton, UK, identified a unique type of stem cells in the eye that can be converted into photovoltaic cells. What is more important is that have the potential to turn the processes associated with blindness due to macular degeneration.
 
Affected by the condition suffer from blurred and "distorted" vision before it completely disappears. To a large extent the cause lies in the loss of photoreceptor cells - cells that require light. In this study, the team of researchers found a way to replace these lost cells and reverse the effects of the condition.
 
Right on the front surface of the eye - between the cornea and sclera, is an area where stem cells have been shown to "behave" as photoreceptor when they are in a suitable environment.
 
For the moment, this environment can be created only in the laboratory. Since stem cells exist in the eyes throughout life, it is believed that with more research in this area, they can be used in future therapies for the treatment of blindness caused by macular degeneration.

Enzymes are proteins which accelerate the chemical reaction in the cell. A special portion of the enzyme which is called "active side" is formed in such a way as to fit with the specific substrate molecules.
 
The enzyme works by binding to one or more specific molecules called "substrate".
 
Connection occurs on the active side. The enzyme and substrate form a complex enzyme substraten.
 
The interaction between the enzyme and the substrate either increases or decreases any of the chemical bonds in the substrate.
 
As a result of the chemical interactions in the active part, to form a new product.
 
He then released from the active start of the enzyme acquires its normal shape and is ready to work again.

Two Americans have been successfully cured of insidious infection with Ebola, says American media. Yesterday the hospital in Atlanta is written 33-year-old Dr. Kent harridan who was adopted there treatment after his stay in West Africa and insidious virus infection against which to date medicine lacked any effective therapy.
 
Physician Dr. Bruce Ribnar, infectious diseases specialist from Emory University Hospital informed the Center for Disease Control that the patient is successfully treated and can return to his family and his community without endangering public health.
 
Days ago was discharged and another patient who has entered into contact with the virus during missionary activity.
 
Experts say that when they found no evidence for the presence of virus in their body.
 
At a special press conference Dr. harridan thanked especially the six doctors and 21 nurses for care during treatment in the hospital, and all that he had help to get experimental treatment and the thousands of others who are his courage.
 
Dr. harridan is infected with dangerous virus while working in Liberia, where he was sent as part of a team of hospital ELWA, medical care in distress by an epidemic of Ebola area. The same body which was sent to Dr. harridan, there is another 23 young doctors.
 
Infektsionistat Dr. Ribnar seek treatment for infection with Ebola forty years. According to him, it is unlikely that the young doctor falls ill again from the same strain of the virus in any of its meetings, as his body has developed immunity against it, but should not overlook the fact that there are other insidious strains of virus.
 
Dr. Ribnar said that the treatment used two experimental medicines but still can not decide about their effect, as this is one the first people on which they are tested. This treatment were subjected to three Liberian doctors reported an improvement in the condition. Adult, however, where the drug was applied ZMapp, has died.
 
The doctor advised when treating patients with Ebola to be approached individually. For recovered can be considered, patients whose blood tests showed no presence of the virus, at least 2-3 days after resolution of symptoms of the disease.
 
According to him, in patients may experience complete recovery, provided that no organ damage.
 
A happy cure have yet to recover their strength, while Dr. Ribnar plans to share the experience of the team in the management of dangerous disease. Some of this information in his words will be presented in specialized medical journals. First, however, new knowledge will get doctors who are trying to keep the epidemic of Ebola.
