Mobile Medicine via iPod/iPhone/iPad Apps

Posted: April 19, 2010 at 8:14 am

NatureVideoChannel — March 31, 2010 — "You might not realize it, but with an iPhone, you also have a stethoscope and a CPR trainer within reach. These are just a few of the more than 2,000 medical applications available on the iPhone, and here we've rounded up ten for you to check out. Whether you're a researcher, doctor, or patient, get ready for your medicine to go mobile."

Smartphones and portable devices for medical education
I use an iPhone Touch to listen to lectures and watch presentations (PDF and video). Amazon Kindle works for the same purpose (PDF only, no video).
However, the external speaker of the iPhone Touch leaves much to be desired in terms of sound quality and volume, and recently, I started downloading the lectures directly to my cell phone (HTC Touch Pro2). The HTC Touch Pro interface is not as polished as the one on the iPod Touch but the device itself is not tied to iTunes and I can easily download audio files from the mobile sites of Google Reader, Bloglines and Google Docs.

Kumbh Mela 2010 – the Festival of Immortals

Posted: April 18, 2010 at 10:33 pm

I just returned from attending the 2010 Kumbh Mela celebration also known to many as the "Festival of Immortals". The celebration is said to be anywhere from 3,000 to 8,000 years old; bringing the holy people of the Hindu religion, their followers, and a few "immortals" together. The event honors the legend of when the Hindu "gods" dropped some of their "amrit" (the nectar of immoratlity) from their pot referred to as Kumbh at 4 spots in India: Allahabad (Prayag), Haridwar, Nasik and Ujjain. The Kumbh Mela in each location takes place every twelfth year; this year being held at Haridwar.

The people who attend the "Ganga Art" ceremony, or sacred bath during the Kumbh Mela, believe taking this bath will make them protected from death aka "immortal" until the next Kumbh Mela. And there are a few who believe with a continuous bathing during each Kumb Mela, they will achieve some form of immortality.

Although I am not a Hindu, I went to the Kumbh Mela, out of curiousity and because I was told that I could possibly meet some real life "immortals" who live amoung the "holy people" of India. One man was said to be somewhere between 150 to 250 years old. There was a story of a 300 year old to 900 year old man who may or may not still be alive. And there was the hope of meeting a legendary man who's age is well beyond 1,000 years of age.

Unfortunately, I did not meet any of these people. However, I did find out much more about the supposed "immortals" and a met a few known people who could easily be well beyond 100 years of age.

I will reveal a few more interesting details of my interesting trip through India in future posts.

Better Sleep, Better Learning? Obstructive sleep apnea can reduce a child’s IQ by 10 points

Posted: April 18, 2010 at 8:13 am

From Science Life Blog at the University of Chicago:

Pediatric obstructive sleep apnea, or OSA, can have long-term, detrimental effects on a child’s cardiovascular and respiratory health. But it can also create neurocognitive effects, such as a reduced ability to learn and retain information.

OSA can reduce a child’s IQ by as many as 10 points, while treatment in children with OSA can improve grades.

AGE Precursor Methylglyoxal Also an Issue?

Posted: April 18, 2010 at 8:12 am

Advanced glycation end-products (AGEs) seem to be important in aging, their buildup effectively a form of damage that harms cellular processes in a number of ways. Here, researchers suggest that an AGE precursor chemical is also problematic: “Oxidative stress is believed to be a very important factor in causing aging and age-related diseases. Oxidative stress is caused by an imbalance between oxidants such as reactive oxygen species (ROS) and antioxidants. ROS are produced from the mitochondrial electron transport chain and many oxidative reactions. Methylglyoxal (MG) is a highly reactive dicarbonyl metabolite formed during glucose, protein and fatty acid metabolism. MG levels are elevated in hyperglycemia and other conditions. An excess of MG formation can increase ROS production and cause oxidative stress. MG reacts with proteins, DNA and other biomolecules, and is a major precursor of advanced glycation end products (AGEs). AGEs are also associated with the aging process and age-related diseases such as cardiovascular complications of diabetes, neurodegenerative diseases and connective tissue disorders. AGEs also increase oxidative stress. In this review we discuss the potential role of MG in the aging process through increasing oxidative stress besides causing AGEs formation. Specific and effective scavengers and crosslink breakers of MG and AGEs are being developed and can become potential treatments to slow the aging process and prevent many diseases.”

On Calorie Restriction Research

Posted: April 18, 2010 at 8:12 am

This release via ScienceDaily summarizes the goals of present day calorie restriction research: “Organisms from yeast to rodents to humans all benefit from cutting calories. In less complex organisms, restricting calories can double or even triple lifespan. It’s not yet clear just how much longer calorie restriction might help humans live, but those who practice the strict diet hope to survive past 100 years old. … calorie restriction influences the same handful of molecular pathways related to aging in all the animals that have been studied. Aware of the profound influence of calorie restriction on animals, some people have cut their calorie intake by 25 percent or more in hopes of lengthening lifespan. [Researcher Luigi Fontana] is less interested in calorie restriction for longer life than in its ability to promote good health throughout life. … Right now, the average lifespan in Western countries is about 80, but there are too many people who are only healthy until about age 50. We want to use the discoveries about calorie restriction and other related genetic or pharmacological interventions to close that 30-year gap between lifespan and ‘healthspan.’ However, by extending healthy lifespan, average lifespan also could increase up to 100 years of age.”
