UC Irvine geneticist Doug Wallace, one of the world’s leading authorities on mitochondria, the so-called “power plant” of cells, has been elected a member of the Institute of Medicine (IOM), the elite health branch of the National Academy of Sciences.

Wallace, 62, becomes only the second person on the current UCI faculty who is a member of three of the most renowned societies in U.S. science — the IOM, the NAS and the American Association for the Advancement of Science. The other professor is F. Sherwood Rowland, winner of the Nobel Prize in chemistry.

UCI spent more than three years recruiting Wallace from Emory University, where he built a reputation not only for his insights into the basic nature of mitochondria but how these so-called “organelles” might be involved in disease, especially diabetes and cancer.

“I am honored and grateful that the work of our UCI team on mitochondrial diseases has been recognized by the Institute of Medicine,” Wallace said by email.  “The mitochondria provide the energy for our cells and systemic energy defects cause symptoms in those organs in our body which require the most energy:  the brain, heart, muscle, kidney, pancreas, etc.  These are the same organs  that are affected by degenerative and metabolic diseases, cancer and aging.  Therefore, the concepts developed by our Center on mitochondrial medicine promise to revolutionize our understanding of the causes of common diseases and to prove new approaches for their treatment.”

Creationists may hand out famed evolution book at UCI

A Bellflower-based Christian ministry that promotes creationism says UC Irvine may be among the campuses where its followers hand out copies of Charles Darwin’s “On the Origin of Species” that includes a 50-page insert disputing the scientific foundation of evolution.

“We’re not saying which campuses we’re going to ahead of time because atheists have threatened to burn the books or take them away,” said Tony Miano, outreach director for Living Waters.

But Miano said UCI “likely” or “could be” one of the campuses because it is a “good-sized school that’s well-known around the country in the sciences.”

Ray Comfort, Living Waters’ founder, also expressed interest in UCI, saying “I like Irvine. If we don’t cover them this time, it’ll  happen eventually. We’re going to give away the books at every university in the country.”

Comfort wrote the 50-page section that’s been inserted into “Origins.” The intro is partly aimed at atheists, whom he says “believe that nothing created everything, which is a scientific impossibility.”

Living Waters plans to distribute up to 175,000 copies of Darwin’s book, with the “special introduction,” during the week before Thanksgiving. The distribution comes 150 years to the month after Darwin’s “On the Origin of Species” was first published. The program is privately funded.

UCI is heavily involved in the study of evolution, and it is the only campus in the country that currently has five evolutionary biologists who are members of the National Academy of Sciences, the honors and research society founded during the Lincoln administration. The campus will open a Darwin exhibit in its main library later this month, featuring material both supporting and opposing evolution. And in December, the NAS center in Irvine will hold a major international conference on Darwin.

The UCI biologists include National Medal of Science winner Francisco Ayala, who said by email this afternoon that he didn’t think atheists would turn out to burn books, and that the insert is, “Typical of the sneaky and somewhat dishonest ways followed by some creationists.”

Cathy Lawhon, director of media relations at UCI, said that any individual or group is permitted to hand out materials on campus “as long as the material isn’t pornographic or an incitement to riot. And they can’t block people’s path.”

Do you think that atheists would destroy copies of the book and special introduction that Living Waters plans to distribute?

UCI will stop using rats in 2 biology classes

UC Irvine says it will stop using rats in two biology classes because the university can meet the “educational objectives of the lab” with the use of computer simulations and other aids.

People for the Ethical Treatment of Animals (PETA) claimed credit for the change, saying in a news release that, “After evaluating PETA’s information about non-animal alternatives to damaging the brains of rats for a neuroscience course experiment, the University of California, Irvine, has announced that it has replaced the use of rats with sophisticated computer simulations.”

But Tom Vasich, a UCI spokesman, said in an email that, “PETA had no involvement with UCI’s decision to evaluate the lab course
or with the ultimate decision to replace some of the live animal
components, but the information on alternatives provided by PETA was
used during the evaluation process …

“The Institutional Animal Care and Use Committee (IACUC) on campus
reviews animal-use protocols for classes every three years.

“In this case, the labs for two Bio Sci classes were undergoing the
regular IACUC protocol renewal process, and based on IACUC input, the
faculty took the opportunity to revisit the lab and to see if the
laboratory could be improved, meet the education objectives and use
alternatives. This evaluation included faculty and student input and
also involved a detailed analysis of computer software and the
educational objectives of the lab. It was concluded that the rats could
be eliminated from the lab and substituted with computer simulations,
histology slides and video.

“This evaluation is part of what IACUC does at UCI — asking laboratories
to think about ways of reducing the number of animals being used while
still meeting the research and/or educational objectives of the project
or class.”

Kathy Guillermo, vice president of laboratory investigations for PETA, said in the news release, “UC Irvine’s decision has given animals who are locked away in its laboratories some newfound hope. At least 200 rats every year will now be spared the fear and pain that resulted from these experiments, and students will be better prepared to pursue careers in modern science.”

Like other large  research institutions, UCI uses thousands of mice and rats in experiments involving everything from the study of cancer to obesity to diabetes.

Legendary UCI researcher van den Noort dies

UC Irvine neuroscientist Stanley van den Noort, who built a nationally-renowned clinic for the treatment of Multiple Sclerosis (MS) while also serving as dean of the university’s medical school, died at his home in Tustin on Wednesday. He was 79.

Van den Noort’s death was announced by his family, who said in a statement that he died “as a result of complications from
a brain injury he suffered over two years ago.”

Van den Noort had been a member of the UCI faculty for almost 30 years, joining the university in 1970 as chair of neurology after 10 years of service at Case Western Reserve in Cleveland.

“From the standpoint of our medical school and the field of neurology, Stanley was truly a giant,” said Ralph V.  Clayman, interim dean of the UCI School of Medicine.

“He was dean for 12 years, he helped open the original (UCI) hospital, a tremendous amount of building went on under his direction, and he created a first class faculty. He also was a super-generous man who focused on researching and treating MS. He was a physician’s physician, not only because many of his patients were doctors but because he exemplified what you want to be as a physician. He gave tremendously of his time and compassion, and practiced until he was in his mid-70s. His patients loved him.”

Van den Noort earned his medical degree from Harvard in 1954 and went to work at Boston City Hospital, the South End medical center that was the basis for the hit television show, “St. Elsewhere.” His family says he later served as a senior resident in neurology, then serving in the US Navy for two years.

After joining UCI, van den Noort emerged as a major researcher and clinician in MS and went on to become chief medical officer and chair of the medical advisory board for the National MS Society, his family says.

In a statement, Dr. John Richert, executive vice president of research and clinical programs. “In his role as chief medical officer of the Society
and chair of the Medical Advisory Board, Stan helped to build awareness, understanding and support for speeding us towards a world free of multiple sclerosis. He will be much missed by all who knew him.”

Van den Noort’s tenure as medical school dean was not without controversy. He was a key figure in an eventually unsuccessful effort to get a hospital built on the main campus. Many people at the university didn’t like the fact that UCI was running an old county hospital (now UCI Medical Center) in Orange.

The battle over the hospital cost van den Noort some political support. But he apparently didn’t care. He told a campus historian,  “I never really took the Deanship very seriously. I was popular and they wanted me to do it. I said I know I’m a good neurologist, but I don’t know if I’m a good Dean or not. I told people that neurologists make very good Deans because they deal with chaos and confusion and don’t expect things to get better; they usually tend to get worse. So, I said we are used to that.”

The university says, “Dr. van den Noort is survived by his wife June; his children Susanne, Eric, Peter, Kathy and Betsy; his grandchildren Aren, John, Jennifer, Melissa, Stephanie, Riley, Tory and Will; and his great grandchild Alex.

“His family has asked that donations be made in his honor to the
following : The van den Noort Multiple Sclerosis Clinical Program, Fund
No. 3042; the van den Noort Neurology Chair’s Research Endowment, Fund No. 7152; and to the National MS Society.”
