A study conducted in Kansas University suggests that Vitamin D deficiency can cause a range of illnesses such as diabetes, blood pressure and cardiomyopathy.
In people with low blood levels of vitamin D, boosting them with supplements more than halved a person’s risk of dying from any cause compared to someone who remained deficient, in a large new study.
Analyzing data on more than 10,000 patients, University of Kansas researchers found that 70 per cent were deficient in vitamin D and they were at significantly higher risk for a variety of heart diseases.
D-deficiency also nearly doubled a person’s likelihood of dying, whereas correcting the deficiency with supplements lowered their risk of death by 60 per cent. Continue reading →
I have had a debilitating parasitic disease in Africa, nearly 2,000 cases of Guinea worm eradication of last year.The Carter Center has been led by shock – since 1986 – Former U.S. President, Jimmy Carter set up by.
International Development (DfID) for the Department to £ 20m drive.It ‘s to think this will help fill a financing gap of about a third. Cabinet and other donors are now calling for a significant contribution.
Although generally it is not murder, grievous hurt, as Guinea worm, and leaves some sufferers to bed-ridden after they drink contaminated water, it contracts.
Months of water after the patient’s body to a meter – long spaghetti-like worm through the skin of a blister emerges.
Endless cycle
Many thousands of insect larva ejects into the water to contact me – the disease is a cycle perpetuating.
There is no cure or vaccine, so the Carter Centre UK aid money tracking outbreaks by using cloths to filter drinking water to help train people and get weight.
Last year, 1,797 Guinea worm in southern Sudan, ithiopiya, Mali and Chad were the case.
Nigeria, Niger and Ghana in recent efforts to wipe out the disease have been followed.
When the Carter Center’s Guinea worm was started 25 years ago in Africa and Asia, there are about 3.5m in 21 countries.
Mr. Carter said: “Guinea worm for the dreadful consequences of their immediate health of the sufferers, and their education and employment.
“I started
President Carter’s commitment to Guinea worm eradication has been edging up. ”
International Development Minister, Stephen O’Brien
“This is to prevent people escaping poverty.
“I laid down a challenge to the British government. I have to match their efforts and call on other donors.”
Rather than a vaccine or drug use – if the campaign succeeds, the first time a disease has been eliminated through the education.
International Development Minister, Stephen O’Brien said: “President Carter’s commitment to Guinea worm eradication has been edging up. “It’s been a question if we can not rid the world of this ancient disease – but when.”
New rules for abortion in Mexico court.
Mexico supreme court has address new law for abortion.
Anti-abortion campaigners now want a similar ruling for San Luis Potosi state
Mexico’s Supreme Court has upheld an amendment to Baja California’s state constitution that stipulates life begins at conception, in a move hailed by anti-abortion campaigners.
Although seven of the 11 justices deemed the measure unconstitutional, eight votes were needed to overturn it.
More than half Mexico’s 31 states have enacted right-to-life amendments that severely restrict abortions.
However, Mexico City allows abortions in the first 12 weeks of pregnancy.
Anti-abortion campaigners cheered after hearing the Supreme Court ruling.
“We have to continue working so that life may triumph,” Jorge Serrano, leader of an anti-abortion organization Pro-Life, told Reuters.
The Supreme Court is due to consider a similar amendment in the state of San Luis Potosi, where the law also says that life begins at conception.
Justice Fernando Franco proposed the motion to declare Baja California’s law unconstitutional but the opposition of four judges sank the measure.
Giving their ruling, the justices said they based their analysis “strictly on constitutional issues. That is, the issue under debate was the power of states to legislate on topics that are not expressly determined by the federal constitution”.
However, some women’s rights activists fear that allowing individual states to decide their own rules may create a divide between those able to go to Mexico City for a legal abortion and those living in states where it is largely restricted.
Mexico City government’s Human Rights Commission said the court’s stance would worsen the serious public health problem of clandestine abortions.
The ruling highlights the difference between policies pursued by Mexico City’s authorities and more conservative administrations in other states, correspondents say.
All Mexican states allow abortion when pregnancy results from rape and most permit it when the woman’s life is in danger.
But pro-choice campaigners say that in practice this does not always happen.

The Nobel Prize in Physiology or Medicine 2011
shall be divided, with one half jointly to
Bruce A. Beutler and Jules A. Hoffmann
for their discoveries concerning the activation of innate immunity
and the other half to
Ralph M. Steinman
for his discovery of the dendritic cell and its role in adaptive immunity
Summary
This year’s Nobel Laureates have revolutionized our understanding of the immune system by discovering key principles for its activation.
Scientists have long been searching for the gatekeepers of the immune response by which man and other animals defend themselves against attack by bacteria and other microorganisms. Bruce Beutler and Jules Hoffmann discovered receptor proteins that can recognize such microorganisms and activate innate immunity, the first step in the body’s immune response. Ralph Steinman discovered the dendritic cells of the immune system and their unique capacity to activate and regulate adaptive immunity, the later stage of the immune response during which microorganisms are cleared from the body.
The discoveries of the three Nobel Laureates have revealed how the innate and adaptive phases of the immune response are activated and thereby provided novel insights into disease mechanisms. Their work has opened up new avenues for the development of prevention and therapy against infections, cancer, and inflammatory diseases.
Two lines of defense in the immune system
We live in a dangerous world. Pathogenic microorganisms (bacteria, virus, fungi, and parasites) threaten us continuously but we are equipped with powerful defense mechanisms (please see image below). The first line of defense, innate immunity, can destroy invading microorganisms and trigger inflammation that contributes to blocking their assault. If microorganisms break through this defense line, adaptive immunity is called into action. With its T and B cells, it produces antibodies and killer cells that destroy infected cells. After successfully combating the infectious assault, our adaptive immune system maintains an immunologic memory that allows a more rapid and powerful mobilization of defense forces next time the same microorganism attacks. These two defense lines of the immune system provide good protection against infections but they also pose a risk. If the activation threshold is too low, or if endogenous molecules can activate the system, inflammatory disease may follow.
The components of the immune system have been identified step by step during the 20th century. Thanks to a series of discoveries awarded the Nobel Prize, we know, for instance, how antibodies are constructed and how T cells recognize foreign substances. However, until the work of Beutler, Hoffmann and Steinman, the mechanisms triggering the activation of innate immunity and mediating the communication between innate and adaptive immunity remained enigmatic.
Discovering the sensors of innate immunity
Jules Hoffmann made his pioneering discovery in 1996, when he and his co-workers investigated how fruit flies combat infections. They had access to flies with mutations in several different genes including Toll, a gene previously found to be involved in embryonal development by Christiane Nüsslein-Volhard (Nobel Prize 1995). When Hoffmann infected his fruit flies with bacteria or fungi, he discovered that Toll mutants died because they could not mount an effective defense. He was also able to conclude that the product of the Toll gene was involved in sensing pathogenic microorganisms and Toll activation was needed for successful defense against them.
Bruce Beutler was searching for a receptor that could bind the bacterial product, lipopolysaccharide (LPS), which can cause septic shock, a life threatening condition that involves overstimulation of the immune system. In 1998, Beutler and his colleagues discovered that mice resistant to LPS had a mutation in a gene that was quite similar to the Toll gene of the fruit fly. This Toll-like receptor (TLR) turned out to be the elusive LPS receptor. When it binds LPS, signals are activated that cause inflammation and, when LPS doses are excessive, septic shock. These findings showed that mammals and fruit flies use similar molecules to activate innate immunity when encountering pathogenic microorganisms. The sensors of innate immunity had finally been discovered.
The discoveries of Hoffmann and Beutler triggered an explosion of research in innate immunity. Around a dozen different TLRs have now been identified in humans and mice. Each one of them recognizes certain types of molecules common in microorganisms. Individuals with certain mutations in these receptors carry an increased risk of infections while other genetic variants of TLR are associated with an increased risk for chronic inflammatory diseases.
A new cell type that controls adaptive immunity
Ralph Steinman discovered, in 1973, a new cell type that he called the dendritic cell. He speculated that it could be important in the immune system and went on to test whether dendritic cells could activate T cells, a cell type that has a key role in adaptive immunity and develops an immunologic memory against many different substances. In cell culture experiments, he showed that the presence of dendritic cells resulted in vivid responses of T cells to such substances. These findings were initially met with skepticism but subsequent work by Steinman demonstrated that dendritic cells have a unique capacity to activate T cells.
Further studies by Steinman and other scientists went on to address the question of how the adaptive immune system decides whether or not it should be activated when encountering various substances. Signals arising from the innate immune response and sensed by dendritic cells were shown to control T cell activation. This makes it possible for the immune system to react towards pathogenic microorganisms while avoiding an attack on the body’s own endogenous molecules.
From fundamental research to medical use
The discoveries that are awarded the 2011 Nobel Prize have provided novel insights into the activation and regulation of our immune system. They have made possible the development of new methods for preventing and treating disease, for instance with improved vaccines against infections and in attempts to stimulate the immune system to attack tumors. These discoveries also help us understand why the immune system can attack our own tissues, thus providing clues for novel treatment of inflammatory diseases.
Bruce A. Beutler was born in 1957 in Chicago, USA. He received his MD from the University of Chicago in 1981 and has worked as a scientist at Rockefeller University in New York, at UT Southwestern Medical Center in Dallas, where he discovered the LPS receptor, and the Scripps Research Institute in La Jolla, CA. Very recently, he rejoined the University of Texas Southwestern Medical Center in Dallas as professor in its Center for the Genetics of Host Defense.
Jules A. Hoffmann was born in Echternach, Luxembourg in 1941. He studied at the University of Strasbourg in France, where he obtained his PhD in 1969. After postdoctoral training at the University of Marburg, Germany, he returned to Strasbourg, where he headed a research laboratory from 1974 to 2009. He has also served as director of the Institute for Molecular Cell Biology in Strasbourg and during 2007-2008 as President of the French National Academy of Sciences.
Ralph M. Steinman was born in 1943 in Montreal, Canada, where he studied biology and chemistry at McGill University. After studying medicine at Harvard Medical School in Boston, MA, USA, he received his MD in 1968. He was affiliated with Rockefeller University in New York since 1970, where he was professor of immunology from 1988. Sadly, Ralph Steinman passed away before the news of his Nobel Prize reached him.
