The First Man Cured of AIDS

Doctor said the man, 45 years in California may be the first person who recovers from AIDS. It is known of his HIV-resistant gene. Like what?

'Timothy Ray Brown' known positive HIV (human immunodeficiency virus) in 1995. Now, he entered the scientific journal as the first person who managed to 'remove' the HIV virus from his body completely. Doctors call this condition 'functional cure'.
In 2008, Brown lived in Berlin (Germany) living with HIV and leukemia. There, scientists perform bone marrow transplants to treat leukemia. Scientists say, Brown received marrow from donors are included in 1% of Caucasians are immune to HIV.
"I stopped going for treatment of HIV in the day I got the transplant," said the man well known with the 'Berlin patient'. Researcher of AIDS Dr. Jay Levy of the University of California, San Francisco (UCSF), said Brown's case opens the door 'healing research'. But , doctors emphasize, Brown radical procedures may not fit with other HIV sufferers because of the difficulty of marrow grafts and find the right donor.
"Surely you do not want to do this transplant because of the risk of death," said Paul Volberding of UCSF. Many questions unanswered about the treatment of Brown, he added. "One element of treatment appears to allow the virus out of his body," he continued. And this will be an interesting study, he concluded.

Lack of Sleep Effects & Obesity

Lack of sleep not only makes the body becomes limp. Moreover, the danger can make us eat more. In fact, the calories burned only little. That's why people who less sleep are usually more susceptible to obesity.
Although so far there has been no strong evidence regarding the mechanisms of obesity and sleep, but some studies did show that sleep should be a priority. "If you want to maintain a diet for ideal weight, do not forget to have enough sleep because sleep is enough and quality is an important part to a healthy body "(Michael Grandner - expert in sleep disorders from the University of Pennsylvania, Philadelphia, USA). Several studies of sleep and obesity has been done in a variety of methods. There are large populations surveyed and interviewed their eating and sleeping patterns and follow their health records. Another study conducted on a small group of respondents in depth. The researchers also manipulated the schedule of respondents sleep and observe whether there are effects on appetite.
In a recent study, researchers from Sweden found in younger people who lack sleep seems nothing has changed on appetite, but their bodies burn calories 50-20 percent less than the people who are quite tidur.Dalam her research, Marie-Pierre St -Onge of the New York Obesity Research Center and his team recruited 30 men and women aged in their 30s and 40s who have normal weight. The participants live and sleep in a sleep laboratory for five days in two periods berbeda.Pada the first period, the participants slept for 9 hours a night. The next period, they may only sleep four hours. In the second period, participants were given a calorie-controlled diet in the first 4 days and then released to eat anything in the last day.
The researchers wanted to know the energy you burn in daily activities and asked the participants how energetic they feel. Test results show no matter how many hours they sleep, the participants in the same amount of calories burned, about 2,600 per hari.Tetapi in the group that lack of sleep, they eat more calories on the last day, about 300 calories. The participants also said they feel less energetic after a few days less tidur.Peneliti suspect that fatigue experienced by people who sleep deprivation can cause them to make unhealthy eating choices. "When we sleep we will more easily follow the wishes of yourself," said Grandner.Di other hand, according to him, uncontrolled diet can also disrupt sleep patterns, such as the stomach so hard sleepy glut.

Efficacy of Frog Skin for Cancer Medicine

Recent research has shown positive results for drug discovery of new species of frog skin for a number of specific types of chronic and hard diseases. Because of their findings, the scientists at Queen's University, Belfast, Northern Ireland, received awards for their research results. The results showed a certain frog skin can be beneficial for the treatment of 70 main diseases. The scientists received awards for medical discoveries, the Medical Futures Innovation Awards, in London.
The study, led by Professor Chris Shaw at Queen's College of Pharmacy was found two types of proteins that can regulate how the blood vessels grow. Group of researchers are the only Northern Ireland team who participated in the race to win the award this year. They found that the protein of certain types of toads (frogs of this type of monkey frog) can inhibit the growth of blood vessels and can be used to kill cells tumor. Profesor Shaw said that most tumor cells can only grow to a certain size before it requires blood vessel cells to grow into the tumor to deliver nutrients and oxygen are very important substances.
"Stopping the growth of blood vessels will reduce the likelihood of spread of the tumor and the tumor can be will kill it," he said. "This has the potential to transform cancer from a deadly disease into a chronic condition." Team led by Professor Shaw also found that a type giant toad (firebellied) produce proteins that can stimulate blood vessel growth and can help cure the patient from injury and surgery more quickly. "This finding has the potential to treat various diseases and conditions that require blood vessels for treatment more quickly, such as treating wounds, transplantation of organs and damage due to stroke or heart disease, "said Professor Shaw.
According to professors, scientists and pharmaceutical companies around the world, despite already spending money to about U.S. $ 5 billion, has not managed to develop a drug that can be a potent hit of the blood vessels, control and manage its growth. "Aim our efforts at Queen's is to opened the door of nature's potential. In this case the substance found in the frog and toad skin is to reduce human suffering. We believe this natural solution to keep the various problems we face. We need to ask the right questions to find solutions, "said Professor Shaw." It would be very unfortunate if nature has something that could potentially be a cure for cancer and we did not try my best to make it worthwhile, "he said.
Responding to the discovery of Professor Shaw and his colleagues, the assessment team member Professor Brian Walker and Dr Chen Tianbao say that they want to encourage scientists to bring their findings to the next level. "The idea of ​​Professor Shaw is really very innovative and exciting in the area that needs not been widely met, "said the assessment team was." It is important to realize that the invention is still in early stages and much effort remains to be done before reaching the stage of clinical medicine, "he concluded
