Light for the Aging and Cancer
Cancer September 29th, 2009
They are “afraid” of the aging process, and argued cancer is an incurable disease, has found the end of the tunnel of light through the discovery that led to the passage said.
Three scientists, Elizabeth Blackburn, Carol Greider and Jack Szostak, Monday (5 / 10), received the Nobel Prize in Medicine in 2009 for discovering and identifying a key mechanism in the cell genetic operations, a discovery which has inspired new research in aging and cancer.
They are, in the late 1970s and the 1980s, has succeeded in solving major problems in biology, “How could chromosomes copy themselves perfectly as divide and how they protect themselves from degradation”, as written in sitat.
This was their second victory in three of them after they won the 2006 Lasker Prize for being able to predict and find an enzyme called telomerase that help block the cell chromosomes stay young. They found the solution at the end of chromosomes, called the telomere is often compared to the plastic at the ends of shoelaces shoelace holding it so as not to decompose (Kompas, 6 / 10). Greider says, “Our approach shows that when we do research to answer anything about the specific disease, we can only do so by following our noses (instincts).”
Deoxyribo nucleic acid molecules (DNA) is long like a thread, the bearer of human genes, collected into chromosomes. The resulting telomere telomerase is closed at the end. Telomere has actually found a few decades earlier, but Blackburn wanted to know how it was copied so they can prevent aging. “Hours do not roll back, but there is the question of how we can extend our health,” he said.
Their work is adjacent to the field of chemical work. Had alleged that they too will both receive Nobel Prize in Chemistry in 2009. “The discovery of Blackburn, Greider, and Szostak has added a new dimension to our understanding of the cell, dropping the light on the mechanisms of disease, and stimulate the development of potential new therapies,” said the Nobel Prize Committee.
Chief Executive British Medical Research Council (Britain’s Medical Research Council) Sir Leszek Borysiewicz said in a statement, “Studies on the chromosome to help lay the foundation of future research on cancer, stem cells, as well as the aging process. These areas are very important. ”
No wait
Blackburn, who was born in Australia and now holds two nationalities, the U.S. and Australia, admitted he was not waiting for a call from the Nobel Prize Committee, although his name at the top of the list of award recipients. “I woke up and needed a time before realizing it,” he added.
He said it had been in Southern California the day before to visit the mother-in-law’s birthday to-95. “The phone rang, and I was groping in the dark to take it,” he said.
Blackburn, who dared to speak bluntly, was fired in 2004 from the Council formation Bioetik U.S. President George W Bush for criticizing its policies related to research on stem cells.
Other research is now conducted Blackburn showed that chronic stress and certain lifestyle behaviors can be lethal telomere and telomerase. This one day will be the entrance of a new understanding of the impact of stress and the emergence of disease-related premature aging process, such as blindness and cardiovascular disease.
To father
Greider dedicate his victory to his father, a physicist, who has encouraged him to plunge into the world of science.
“He’ll say, ‘We can do whatever you want to do, but you have to love what you do’,” he recalled his father.
He began a study telomerase in the late 1970s by Blackburn, who pioneered the academic advisor research on chromosomes and DNA at the University of California. He added that the Nobel Prize is recognition of the value of discovery-driven pure curiosity.
Stephen Desiderio, Director of the John’s Hopkins Institute for Basic Biomedical Sciences, where Greider worked, insisting, “As a fellow scientist, mentor, and women in the scientific world, he was the inspiration for this nation and the world.” Victory Greider made a very good university.
Greider says, “Our approach shows that when we do research to answer anything about the specific disease, we also can only do so by following our noses (instincts).”
Highest
Meanwhile, Szostak at the award as the highest award. So, a lot of fun receiving such recognition, and anyway could share with his classmates, colleagues. “I think we need a balance between basic science and applied research,” he said.
Szostak had since the 1970s constantly researching telomerase. According to Berg, “He’s trying to find how he can make a proto-cells and makes copying its genetic material. This is equivalent to actually create life in test tube. ”
Some companies have tried to get the telomerase research. Geron Corp. of Menlo Park, California, has launched a clinical trial to test the telomerase to see the possibilities to fight cancer.
There is no cure or treatment is in sight. UCSF counselor Susan Desmond-Hellmann says, “Research Blackburn became very important for the biotechnology and pharmaceutical companies.” He was previously chief executive of biotechnology company Genentech.
Milk cause Acne
Acne, Skin Care September 28th, 2009
The relationship between food with skin problems has long been a spotlight on dermatology experts. One of them is the relation between consumption of milk with acne.
Alan Logan, ND, author of The Clear Skin Diet, says that milk consumption should be reduced if you want to have acne free skin. According to him, even though milk including foods with low glycemic index, but milk contains many hormones.
“Hormones in milk, together with high calcium, for many years been suspected as the cause of acne,” said Logan.
The dermatologist suspected memercepat milk synthetic androgen in the body, namely that there are male hormones in the body of women and men. Androgen hormones cause the sebaceous (oil) glands produce more oil. Acne occurs when sebum that normally come out to the skin surface is blocked.
A study published in The Journal of the American Academy of Dermatology also showed a link between milk and acne. In a study of 47,335 women surveyed had known women who drank two glasses of milk or more each day acne problems. Read the rest of this entry »
Sport VS Diet
Diet Tips September 28th, 2009
When slender with weight stayed up into your dreams, then begin to limit your calorie intake. According to Donald Hensrud, MD, of Mayo Clinic, reduce your calorie intake is more effective against the increasing frequency of obesity than exercise.
Lock against obesity is essentially the number of calories burned must be greater than that consumed. According to Hensrud, 3500 calories equals 1 pound (0.45 kg) of fat. So, if you want to down 1 pound per week, that means you have to reduce 500 calories from your diet every day (500 calories x 7 days).
Still, it does not mean exercise is not in the dictionary, because it desperately dieting without physical activity will not produce optimal results. “With exercise, the excess fat that can not be deducted from the diet can be burned,” said Hensrund. Read the rest of this entry »
The sound of buzzing in the ears is Early Alert of Deaf
Health News September 26th, 2009
gyjhszenpt.There is a myth that states that a sign buzzing in the ears of others were talking about us. But do not think is trivial first, because researchers in the United States said that the ears are buzzing early signs of going deaf person.
Got iPod and can enjoy the music each time it is nice. But be careful, the researchers predict that within 15 to 20 years, the younger generation who often listened to iPod could be a lost generation of hearing.
Researchers in the U.S. reported that most adolescents and adults now have the same hearing people aged 50 years. After investigation, it turns out they are always listening to iPod and MP3 every day. Read the rest of this entry »
Cotton is New Source of Protein
Health Care September 26th, 2009
Besides the clothing materials, cotton is now used as food ingredients. Researchers found a high protein content in cotton and can be used as a source of new proteins. Want to try to eat cotton?
Plants that have been developed 7000 years ago, now has support of about 20 million farmers in 80 countries. Nearly 40 percent of cotton is used as raw material to make clothing.
But there is one thing missing from the cotton, the cotton can also be used as nutritious food.
Seed cotton is a source of very high protein. However, seed cotton can be consumed only after going through the process of purification of gossypol, a toxic chemical which functions to protect plants from insects and microorganisms. Read the rest of this entry »
