Mercury News | 03/12/2004 | As stem cell research faces attacks, regenerative medicine grows: "Ultimately, these discoveries could usher in regenerative medicine. The idea is to turn a patients' skin cells into embryo-like cells that could be coaxed into growing into replacement tissue for failing organs.
The biggest game being stalked in this hunt is finding the still theoretical genes that launch creation of the human body from a single cell.
Scottish and Japanese researchers last year isolated an ``immortality gene'' in mice that allowed stem cells to grow indefinitely in the laboratory. They dubbed it Nanog, from the Celtic mythical land called Tir nan Og, where everyone stays young. The discovery hastened the race to find a similar human gene and prompted serious scientists to publicly discuss for the first time what they've been quietly pursuing for years.
``We are dreaming of finding that master gene in the egg,'' said Michigan State University researcher Jose Cibelli, a pioneer in cloning and stem cell science. ``The fountain of youth is in the egg.''
The goal of Cibelli and others is to reprogram cells to reverse the aging process -- until stem cells appear.
Embryonic stem cells are the most sought after stem cells. Created in the first days after conception, they give rise to the human body.
Scientists hope to harness this powerful ability of so-called undifferentiated cells to grow into replacements for lost or damaged cells in treating a wide range of ailments, from Alzheimer's disease to spinal cord injuries."

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking ...

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the...

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
