The Nobel Prize 2009

The highly coveted Nobel Prize has just been announced for 2009. Since 1901, it has been highlighting extraordinary achievements in physics, chemistry, physiology or medicine, literature and peace.

This year’s award for Physiology or Medicine goes to Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak for their work with Chromosomes. Their powerful research examines the telomeres, the “shoelace tip” like end caps of a strand of DNA. As cells in our bodies reproduce and age, fragments of nucleotides are lost from the ends of each strand of DNA. The telomeres slow or prevent the fission of that genetic information. This has powerful ramifications for functional Medicine with applications towards the normal aging process and degenerative diseases like Parkinson’s and Alzheimer’s.

Likewise, this year’s Nobel Prize for Chemistry delves into the inner depths of a cell to explore its Ribosome. Using X ray Christalography, Venkatraman Ramakrishnan, Thomas A. Steitz, and Ada E. Yonath mapped every individual atom in a Ribosome to determine how its form leads to its little understood functions. The Ribosome is the “chef” of a cell, reading the “recipe” of DNA to “cook up” proteins essential for life. The Medical application of this research is limitless, the most forefront of which is in developing new antibiotics. By targeting the Ribosome of a virus, antibiotics can be developed to attack the newer drug-resistant infections by destroying it’s Ribosome.

Brain scans gauge horror flick fear factor

How frightened are you really?!?
To find out what exact moment in a horror movie truly makes you frightened has so far been fairly undiscovered. The only method to measure the degree of fright up to now was relying on “focus group testing that involves viewers filling out questionnaires after watching a test screening. The problem with this approach is that often audiences find it difficult to accurately remember and articulate how they felt about certain sequences.” But this imprecise approach is unacceptable for film producer Peter Katz,…

“Pop Skull” producer Katz wants to identify precisely how frightened his audience is down to an exact moment in a scene! "I wanted to understand how we can make a horror film quantifiable," Katz told CNN, explaining the inspiration behind the experiment. "On the timing, I wanted to see just how precise we can get." To do that, Katz decided to start working together with researchers using MRI scans of brain function, providing filmmakers with a perfectly accurate picture of how their audience really feels. This should help spotting movie scenes that don’t work and turn them into true entertainment.

For a start, Katz and his team scanned the brain’s activity of one woman while she was watching a sequence of Katz’s movie. More precisely, the researchers analyzed to what degree the woman’s amygfala – the part of the brain linked to several emotions including fear – was activated. This is how they were able to pinpoint the exact moment she was thrilled with fear the most. Even though, at this point the method needs to be developed and improved; to a great extent it is currently too expensive and time-consuming. Some even argue that by scanning people’s brains, the true art of making a movie isn’t what it used to be. Katz believes that in today’s social networking world, people have more influence on success/flop of a movie than ever before and this is why filmmakers should take advantage of this new opportunity to collect real, honest audience opinions

"Now more than ever you want to make sure that people are satisfied. You can kill a film over Twitter."

Let Peter Katz himself explain to you:

Study: Age at Time of Stroke Decreasing, Discharges Taking Place Without Participation Consideration

Experiencing a stroke is just an ‘old people’s issue’!? If you agree, then you should definitely reconsider your point of view. “According to new research at Washington University School of Medicine in St. Louis published in the September/October 2009 issue of the American Journal of Occupational Therapy, 45% of the 7,740 study patients who had been hospitalized at Barnes-Jewish Hospital with a diagnosis of stroke were less than 65 years old and nearly 27% were less than 55. Compare this to the statistic provided by the National Institutes of Health: two-thirds (66%) of all strokes occur in people over age 65”, obviously implying the other third of people suffering from Stroke are under 65 years old!

Stroke Strikes Fast: How to Respond The National Stroke Association wants you to know the symptoms of a stroke so you can act fast and possibly save your own or a loved one’s life. The F.A.S.T. method for recognizing and responding to stroke symptoms: F = FACE Ask the person to smile. Does one side of the face droop? A = ARMS Ask the person to raise both arms. Does one arm drift downward? S = SPEECH Ask the person to repeat a simple sentence. Does the speech sound slurred or strange? T = TIME If you observe any of these signs, it’s time to call 9-1-1 or get to the nearest stroke center or hospital (National Stroke Association, 2009).

“The needs of a younger person with stroke go far beyond those of the older population,” said study co- author Timothy J. Wolf, OTD, MSCI, OTR/L, instructor of occupational therapy and neurology and investigator for the Cognitive Rehabilitation Research Group (CRRG) at Washington University. “This includes family issues, work, driving, marriage responsibilities and community participation. US rehabilitation programs are not organized to serve these needs. In fact, this study demonstrated that many of these people get minimal or no services after stroke. Study patients who had a mild to moderate stroke — approximately 82% — were usually discharged directly home (71%), discharged with home services only, or discharged with outpatient services only.”

However, these services do not provide all the necessary support which is urgently needed to integrate people back into their usual life after stroke. “Specifically, 46% reported working slower, 42% reported not being able to do the job as well, 31% reported not being able to keep organized and 52% reported not being able to concentrate.”

As a matter of fact, one has to consider other solutions enabling stroke patients to finally get back to their old lives. Stephanie Yamkovenko, AOTA’s (American Occupational Therapy Association) staff writer, suggests occupational therapy as one possibility. Occupational therapy practitioners work with stroke patients in depth; considering their needs, desires, activities, environment and new limitations. Furthermore, occupational therapy practitioners can help make the process of rehabilitation more productive and effective for the individual’s needs. They address the physical, cognitive, and mental challenges brought on by a stroke, and can help stroke survivors regain their ability to engage in daily activities through a variety of evidence-based methods.

“Research shows that occupational therapy should be a part of the rehabilitation process because it effectively improves a client’s occupational performance, allowing him or her to live life to its fullest”, says Stephanie Yamkovenko.

3B BONElike™ Youth Vertebral Column

This true-to-life model of the vertebral column of a five-year-old child is especially interesting for those working in the areas of anatomy, pediatrics, orthopedics and pediatric radiology. Cast in unique BONElike™ material the model is almost visually indistinguishable from a real human spine.

The flexible vertebral column including occipital plate, pelvis and sacroccyx is mounted on a removable stand. Within the spinal canal, the spinal cord with cauda equina and exiting nerve roots are represented in flexible material.

This youth vertebral column is particularly useful to study the phases of bone growth. This includes:

• Vertebrae - partially incomplete development of vertebral bodies and vertebral arches
• Sacrum - as yet incomplete fusion of individual sacral vertebraem which being at around the age of 15.
• Pelvis - still open Y cartilage as main growth plate of the acetabulum. The hip, pubic and ischial bone parts are not yet connected (didactically fixed with brackets in the model). These fuse around the age of 14-16.

Here's what 3B customers are saying about 3B BONElike™:
“… A unique reproduction of a bone that cannot be distinguished from a real one. One of my staff members, a world-wide renowned bone specialist, was not able to distinguish the vertebra from a real one. I wish your company much success with your excellent artificial preparations.” -Prof. Dr. Dr. h.c. Horst Erich König, Director, Institute for Anatomy, University of Veterinary Medicine, Vienna

“… I am convinced that you have developed the best bone ever created by man.” -Prof. Vladimire Ovcharov, MD, DSc, Rector Medical University - Sofia

“Thank you very much for sending a vertebral body model. It was a pleasant surprise for me as a keen anatomist. In the first moment, I actually believed it was real bone! My compliments, the material has excellent tactile feel.” -Yvonne Kammerer, MD Institute of Anatomy, University of Regensburg, Germany

“This model has an “aged” look that makes it appear like a real specimen. All the teeth are present and fine structures like the styloid process, sphenoidal spine and pterygoid hamulus are all pristine. These fragile structures usually break shortly after students get their hands on a skull. However, in their plastic state they are stronger and likely to withstand the rigors of use better than the original. This is also true of thin areas such as the lamina papyracea and other parts of the orbital wall, which, though recognizable on the model, are unlikely to break as readily as a natural specimen would. One could say that the model has gained strength and durability at, perhaps, some small trade-off with realism, but this is exchange is well worth making for primarily a teaching tool.” -David Rapaport, Ph.D., Division of Anatomy, Department of Surgery, University of California, San Diego
