Q :
I was diagnosed with MS in 2001, I go through episodes when breathing becomes difficult and will have to focus on getting a deep breath by yawning. I feel like I am suffocating but I know that I am not. Eating definitely aggravates the feeling. Any ideas on the cause and why I feel like this?
A :
Excessive yawning has been reported with a number of different neurologic conditions, including MS. In MS, it is believed to be due to involvement of the brainstem by MS plaques, yet it occurs only in a very small number of people with MS with brainstem involvement. Excessive yawning can also occur as a prodrome before migraine and this is actually fairly common so if you have headaches (migraine affects about 18 % of women and 6% of men in the population), watch for this connection. Excessive yawning can also occur with certain medications, including certain commonly used anti-depressants that work on serotonin (the SSRIs or selective serontonin reuptake inhibitors). The feeling of suffocating can sometimes be a symptom of anxiety. I am not sure why eating would aggravate the symptoms. It might be helpful to discuss these episodes in greater detail with your physician to determine if your MS, anxiety, medication side effects or some other medical condition is causing your symptoms.9/9/2008 9:09:15 PM

1. Salary survey shows big hike in scientists' pay

By John Carroll

U.S. life scientists are feeling somewhat flush these days. The Scientists' fifth annual salary survey shows that median compensation in the U.S. jumped 15 percent since 2006, rising from $74,000 to $85,000. As usual, industry scientists set the pace, at $107,000 a year compared to $77,900 for academics and private institutions. And a growing slice of the annual take-home is coming in the form of bonuses. Close to 12 percent of company pay is provided for bonuses now, compared to only 3.8 percent in 1991.

The salary survey also shows some big gaps between women and men in science. Female professors with 15 to 19 years experience earned a median salary of $126,000 compared to $164,000 for men. And the coasts offered more than anyplace in between. Tenured faculty earned $150,000 in California while the younger set of assistant professors can often earn more than $100,000 in Massachusetts.

2. New genetic map used to advance drug research

By John Carroll

Using what we know already about genomics and genetic variations, researchers can pinpoint a person's geographic origins in Europe within a range of just a few hundred kilometers. And the increasing clarity of that genetic map can help researchers better understand the role genes play in the development of diseases.

Focusing entirely on genetic variations, researchers developed algorithms that could predict geographic origin--even the origination of specific ethnic groups inside Switzerland. GlaxoSmithKline participated in the study so it could gain a clearer understanding of the role pharmacogenetics could play in understanding the genetic risks posed by drugs.

"They are interested in pharmacogenetic purposes to do case control studies of adverse drug reactions," said John Novembre, a co-author of the study published in Nature.

"The idea is to save money in these large-scale genetic epidemiological studies," said Michael Krawczak, who took part in a similar study published in the Current Biology. "It's very costly to genotype people."

But if you establish genetic control groups you can test a drug against populations to understand where the greatest benefits lie, added Krawczak.

3. ESCs provide a key to new blood supply

By John Carroll

When scientists talk about the potential embryonic stem cells have in treating disease, they often focus on a relatively distant horizon when new therapies can be developed to cure some of the world's most complex diseases. But the New York Times points to a not-so-distant time when ESCs may be used to create a virtually unlimited supply of blood free from the risk of disease presented by donors.

To get there, the Defense Advanced Research Projects Agency--a key player in biomedical research--has begun a blood pharming project that will explore just how feasible that can be. The work has been advanced by Advanced Cell Technology, a stem cell company that has a troubled financial record, but a history of high-profile breakthroughs. They recently reported making 10 billion to 100 billion red cells after starting with a platelet of ESCs.

"It's the first time to my knowledge that anyone has been able to produce these on a sufficient scale to talk of using them for transfusion purposes," the co-author of the paper, Dr. George Honig of the University of Illinois at Chicago, tells the NYT.

4. Researchers map the cancer genome

By John Carroll

Several studies published this week suggest that new ways of approaching the treatment of cancer is on the horizon. Scientists are attempting to use gene sequencing machines to identify the mutations that cause cancer, which they hope will allow for differentiated treatment to patients based on the genetic profile of their tumor. In addition, gene sequencing could also lead to developments in the way doctors test for cancer. A catalog of mutations for different tumors could allow doctors to test patients for the presence of DNA or dislodged cells from tumors much earlier.

The studies bring to light a number of barriers to identifying successful targeted treatments. They have found that the number of key genes that frequently mutate is much larger--and that the machinery of cancerous tumors is much more complicated---than expected.

Researchers working on the cancer-genome project at Johns Hopkins University published two separate papers in Science on pancreatic and brain cancer. A third study on brain cancer--funded by the NIH and published in Nature--is part of a $100 million, three-year pilot project called the Cancer Genome Atlas Research Network. They are currently attempting to map ovarian, lung and brain cancer, but if all goes well, the project may be expanded to include up to 50 common human cancers.

Last year, the Atlas project drew criticism from a number of prominent scientists who argued that it is a waste of money to catalog the mutations of primary tumors as they are not the chief threat. According to those researchers, the more serious threat are the malignant cells that cause the rapid spread of cancer throughout the body.

5. Bioprospecting finds fertile grounds in frozen Arctic

By John Carroll

The extreme Arctic climate has given rise to a new era of bioprospecting in the frigid region. The arctic squirrel, for example, can lower its body temperature below freezing--the only mammal known to do so. And that has led researchers to set out and determine if proteins from the animal can be used to repair stroke damage.  There are a total of 31 known patents for Arctic organisms, and fully two thirds of them are held by U.S. companies. Only three Canadian companies have taken up the hunt, though, while tiny Iceland has 10.

"Bioprospecting is not just for the tropical countries," says international attorney David Leary. And Norway has the world's most advanced Arctic marine biotechnology facilities.
