We’ve heard of surgeons using a SpectroPen
during the tumor removal surgeries, but now Californian scientists are shedding light on cancer, literally, in the hopes to find a new cure for skin cancer
. The team of scientists from the University of California, Irvine are currently developing new techniques to image cancerous lesions using LEDs
(light emitting diodes) with the hope of then being able to treat skin cancer using photodynamic therapy (PDT).
The cloning of human viruses may sound like the stuff of biological warfare, but breakthroughs in the area are helping in the development of antivirals and vaccines for life-threatening diseases. Now Welsh scientists have made the first complete copy of the virus Human cytomegalovirus (HCMV) – a common infectious disease that is responsible for congenital malformations and potentially deadly to transplant patients or HIV/AIDS carriers.
As recent scares with the avian and swine flu have so vividly reminded us, influenza can involve a lot more than just feeling lousy and throwing up. In fact, according to the World Health Organization, 250,000 to 500,000 people die annually from the virus. We should be glad to hear, therefore, that researchers believe they are closing in on a cure for the flu. Scientists at Mount Sinai School of Medicine have discovered a component of the virus that may hold the secret to keeping it from being able to self-replicate.
An Italian doctor has been getting dramatic results with a new type of treatment for Multiple Sclerosis, or MS, which affects up to 2.5 million people worldwide. In an initial study, Dr. Paolo Zamboni took 65 patients with relapsing-remitting MS, performed a simple operation to unblock restricted bloodflow out of the brain - and two years after the surgery, 73% of the patients had no symptoms. Dr. Zamboni's thinking could turn the current understanding of MS on its head, and offer many sufferers a complete cure.
When English chemist John Dalton first wrote about color blindness in 1798, he must have wondered how science would improve the quality of life for people living with the condition. Today, spectacles, contact lenses and revolutionary corrective eye surgery combat the effects of a myriad of vision disorders, yet people with color blindness still live in quiet acceptance of this common genetic disorder. Now researchers have delivered promising results by successfully treating two squirrel moneys with defective color perception using a gene therapy that could also safely eradicate color blindness in humans.
Peanut allergies are very common - something like one in every 200 children will suffer from some sort of reaction, and while roughly 100 people per year die as a result, peanuts are still thought to be the most prevalent food-related cause of death. Certainly, for those afflicted, it's a huge annoyance to be constantly checking labels and asking at restaurants just to make sure. So it's good to hear that Duke University researchers are making progress on a cure - or at least a therapy for reducing the effects of peanut exposure.
According to a report in the Israeli newspaper, Yediot Ahronoth, US and Israeli researchers have developed a drug that offers protection from the damaging effects of radiation sickness. The medication could not only provide effective protection in the event of a nuclear or “dirty bomb” attack, but it could also enable cancer patients to be treated with more powerful doses of radiation.
May 22, 2007 Sitting still at a desk all day - like you're probably doing right now - is making the average office worker fatter and less healthy than we've ever been before. Gym workouts and regular exercise are not the key to breaking out of this cycle - a new study suggests that it's the sitting down that's killing us, and that a simple change to spending 2-3 hours a day gently walking at around 1mph while we work could help obese office workers lose up to 30kg a year. Dr. James Levine devised the walk-at-work treadmill to test the effectiveness of getting office workers off their butts - with fantastic results.
May 22, 2006 The production, trade and consumption of alcohol dates beyond 10,000BC
. The Sumerians, Egyptians and Babylonians produced and traded alcohol and the Romans and Ancient Greeks had wine Gods. Across the centuries, almost every culture has used alcohol medicinally, ritualistically and socially and in so doing, woven it inextricably into global society. We now consume more alcohol per person than ever before and at least 2.0 billion people drink it regularly. Which means the number of hangovers faced each day is also on the increase and why an effective hangover cure is the holy grail of “killer apps” – it is a “must have” product that no old wives tale has yet tackled successfully. As the word intoxication suggests, alcohol is actually a poison. That’s why we sometimes vomit when we drink it (to expel the poison), and why, if you drink enough of it, you will die. This new breed of hangover cure addresses the toxicity. The cure we tested and found to be remarkably effective is called Kampai
, which is the Japanese equivalent to slainte, salute, prost, googy wawa (Zulu)
, which is also the name for another clinically proven hangover cure we reported on but didn’t try. We tried Kampai and it works. We tried it every which way and it significantly reduces the after effects of a night on the town more than anything we’ve previously tried, though we invite any hangover cure peddlers to send us a box and we’ll report on them too. We think Cheerz and Kampai, or any other cures as good as they clearly are, should be stocked wherever customers are asked to “name their poison”, because now there’s an antidote, too.
February 9, 2006 Vanderbilt University
, Brigham Young University
and Ceragenix Pharmaceuticals
have announced that one of a family of compounds, called Ceragenins (or CSAs) shows potent virucidal activity in in vitro laboratory tests against multiple strains of Human Immunodeficiency Virus (HIV), the virus that causes AIDS. CSAs were invented by Dr. Paul D. Savage
of Brigham Young University's Department of Chemistry and Biochemistry and exclusively licensed to Ceragenix. In data previously presented by Dr. Savage and other researchers, CSAs have been shown to have broad spectrum antibacterial activity. Dr. Derya Unutmaz
, Associate Professor of Microbiology and Immunology at the Vanderbilt University School of Medicine, tested several CSAs in his laboratory for their ability to kill HIV directly and whilst cautious, acknowledged that CSAs could be the breakthrough technology to combat HIV/AIDS researchers the world has been waiting for.
