Low vitamin D linked with lower kidney function after transplantation

Vitamin D supplements may help maintain kidney function in transplant recipients

2013-03-29
(Press-News.org) Highlights Low vitamin D levels measured at three months after kidney transplantation were linked with lower kidney function and increased kidney scarring at 12 months post-transplant. Other hormones involved with mineral metabolism were not predictors of kidney function or scarring after one year.

Vitamin D deficiency is prevalent in patients with kidney failure.

Washington, DC (March 28, 2013) — Vitamin D deficiency may decrease kidney function in transplant recipients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The finding suggests that vitamin D supplementation may help improve the health of kidney transplant recipients.

Vitamin D deficiency is prevalent in patients with kidney failure. It's not clear how this affects patients after they receive a kidney transplant. To investigate, Frank Bienaimé, MD (Université Paris Descartes and INSERM and Assistance Publique Hopitaux de Paris) and his colleagues studied a group of 634 kidney recipients who underwent transplantation between January 2005 and June 2010.

The researchers found that low vitamin D levels measured at three months after transplantation were linked with lower kidney function and increased kidney scarring at 12 months post-transplant. Other hormones involved with mineral metabolism were not predictors of kidney function or scarring after one year.

"This result suggests that maintaining vitamin D concentration within the normal range would prevent renal function deterioration after renal transplantation," said Dr. Bienaimé. "Vitamin D supplementation, a simple and inexpensive treatment, may improve transplantation outcomes." He encouraged the design of randomized controlled trials to evaluate the potential of vitamin D supplements to maintain kidney function following transplantation.

Discovery opens door to efficiently storing and reusing renewable energy

2013-03-29
Two University of Calgary researchers have developed a ground-breaking way to make new affordable and efficient catalysts for converting electricity into chemical energy. Their technology opens the door to homeowners and energy companies being able to easily store and reuse solar and wind power. Such energy is clean and renewable, but it's available only when the sun is shining or the wind is blowing. The research by Curtis Berlinguette and Simon Trudel, both in the chemistry department in the Faculty of Science, has just been published in Science – one of the world's ...

Light may recast copper as chemical industry 'holy grail'

2013-03-29
ANN ARBOR—Wouldn't it be convenient if you could reverse the rusting of your car by shining a bright light on it? It turns out that this concept works for undoing oxidation on copper nanoparticles, and it could lead to an environmentally friendly production process for an important industrial chemical, University of Michigan engineers have discovered. "We report a new physical phenomenon that has potentially significant practical implications," said Suljo Linic, an associate professor of chemical engineering, who led the study, which is published in the March 29 issue ...

Biological transistor enables computing within living cells, Stanford study says

2013-03-29
STANFORD, Calif. — When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity. Today, computers use transistors made from highly engineered semiconducting materials to carry out their logical operations. And now a team of Stanford University bioengineers has taken computing beyond mechanics and electronics into the living realm of biology. In a paper to be published March 28 in Science, ...

Eating more fiber may lower risk of first-time stroke

2013-03-29
Eating more fiber may decrease your risk of first-time stroke, according to new research in the American Heart Association journal Stroke. Dietary fiber is the part of the plant that the body doesn't absorb during digestion. Fiber can be soluble, which means it dissolves in water, or insoluble. Previous research has shown that dietary fiber may help reduce risk factors for stroke, including high blood pressure and high blood levels of low-density lipoprotein (LDL) "bad" cholesterol. In the new study, researchers found that each seven-gram increase in total daily fiber ...

Innate immune system can kill HIV when a viral gene is deactivated

2013-03-29
Human cells have an intrinsic capacity to destroy HIV. However, the virus has evolved to contain a gene that blocks this ability. When this gene is removed from the virus, the innate human immune system destroys HIV by mutating it to the point where it can no longer survive. This phenomenon has been shown in test tube laboratory experiments, but now researchers at the University of North Carolina School of Medicine have demonstrated that the same phenomenon occurs in a humanized mouse model, suggesting a promising new target for tackling the virus, which has killed nearly ...

Rise in CF patient infections explained

2013-03-29
Researchers at Papworth Hospital, the University of Cambridge and the Wellcome Trust Sanger Institute have discovered why a new type of dangerous bacterial infection has become more common among people with Cystic Fibrosis around the world. Through their ground-breaking research, the team has developed new measures to protect Cystic Fibrosis patients. People with Cystic Fibrosis are prone to serious infection in part because they have sticky mucus that can clog up their lungs. In recent years doctors have seen a global increase in the number of infections caused by ...

Even graphene has weak spots

2013-03-29
HOUSTON – (March 28, 2013) – Graphene, the single-atom-thick form of carbon, has become famous for its extraordinary strength. But less-than-perfect sheets of the material show unexpected weakness, according to researchers at Rice University in Houston and Tsinghua University in Beijing. The kryptonite to this Superman of materials is in the form of a seven-atom ring that inevitably occurs at the junctions of grain boundaries in graphene, where the regular array of hexagonal units is interrupted. At these points, under tension, polycrystalline graphene has about half ...

New vaccine-design approach targets HIV and other fast-mutating viruses

2013-03-29
LA JOLLA, CA – March 28, 2013 – A team led by scientists from The Scripps Research Institute (TSRI) and the International AIDS Vaccine Initiative (IAVI) has unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses. The report, which appears March 28, 2013, in Science Express, the early online edition of the journal Science, offers a step toward solving what has been one of the central problems of modern vaccine design: how to stimulate the immune system to produce the right kind of antibody response to ...

Researchers unveil large robotic jellyfish that one day could patrol oceans

2013-03-29
Virginia Tech College of Engineering researchers have unveiled a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds. The prototype robot, nicknamed Cyro, is a larger model of a robotic jellyfish the same team – headed by Shashank Priya of Blacksburg, Va., and professor of mechanical engineering at Virginia Tech – unveiled in 2012. The earlier robot, dubbed RoboJelly, is roughly the size of a man's hand, and typical of jellyfish found along beaches. "A larger vehicle will allow for more payload, ...

Beaumont doctors call for training to reduce sudden cardiac arrest fatalities in schools

2013-03-29
One of the leading causes of death in the United States is sudden cardiac arrest, which claims the lives of more than 325,000 people each year. In a study published in the April issue of the journal Resuscitation, Beaumont doctors found that cardiac arrests in K-12 schools are extremely rare, less than 0.2 percent, but out of 47 people who experienced cardiac arrest over a six-year period at K-12 schools, only 15 survived. Survival rate was three times greater, however, when bystanders used a device called an automated external defibrillator, or AED, that helps the heart ...
