Cristina Sanchez, a young biologist at Complutense University in Madrid, was studying cell metabolism when she noticed something peculiar. She had been screening brain cancer cells because they grow faster than normal cell lines and thus are useful for research purposes. But the cancer cells died each time they were exposed to tetrahydrocannabinol (THC), the principal psychoactive ingredient of marijuana. Instead of gaining insight into how cells function, Sanchez had stumbled upon the anti-cancer properties of THC. In 1998, she reported in a European biochemistry journal that THC “induces apoptosis [cell death] in C6 glioma cells,” an aggressive form of...

As the political season heats up this Fall, a new television ad campaign has been released to the airwaves by Americans For Prosperity. If you’re like me, you’ve heard the stories over the years of Canadian citizens coming in droves across our northern border for decent health care (legally, I might add). In the latest Americans For Prosperity video ad, we hear the story of one Shona Holmes, a Canadian citizen who relied on American healthcare for her own wellbeing. “The American system was there for me when I needed it,” said Shona. “It’s time for American’s to get engaged...

Scientists have discovered a chemical extract in green tea that can treat two types of skin cancer, without producing the harmful side effects associated with chemotherapy.While the epigallocatechin gallate (EGCg) compound is too weak to make an impact when consumed in tea, scientists were able to kill or shrink two-thirds of cancer cells within a month when they applied the extract to tumor cells in the lab. What's more, the chemical compound did not appear to affect any other healthy cells or tissues in the body.Researchers from the universities of Strathclyde and Glasgow believe that their study is the first...

The prepper can take many lessons from the situation that developed in New Orleans following Hurricane Katrina. One lesson is that when the social order breaks down for a period of days or weeks, adequate medical care will disappear. So preparedness requires a medical kit. And no medical survival kit is complete without a good book or two on emergency medicine, anatomy, drug reference and medical terminology. Some good ones to choose from are:

There are 600,000 physicians in America who care for the 48 million seniors on Medicare. Of the $716 billion that the Affordable Care Act cuts from the program over the next ten years, the largest chunk—$415 billion—comes from slashing Medicare’s reimbursement rates to doctors, hospitals, and nursing homes. This significant reduction in fees is driving many doctors to stop accepting new Medicare patients, making it harder for seniors to gain access to needed care. Here are a few of their stories. Paul Wertsch is a primary physician in Madison, Wisconsin. In 1977, he and his two partners invested $500,000 of...

(CBS News) An ingredient used in artificial butter flavoring for popcorn may worsen the effects of an abnormal brain protein that's been linked to Alzheimer's disease. A new study in Chemical Research in Toxicology examined diacetyl (DA), an ingredient used to produce the buttery flavor and smell in microwave popcorn, margarine, candy, baked goods, and even pet food. It is also created naturally in fermented drinks like beer, and gives some chardonnay wines its buttery taste, according to the study. Scientists at the University of Minnesota in Minneapolis conducted an analysis of DA, a chemical which previously has been linked...

One of the world's oldest vaccines now has a new use. Bacillus Calmette-Guerin, or BCG, is an 80-year-old vaccine designed to tread tuberculosis. Bit it has now been found effective in treating long-term type 1 diabetes, which is on the rise worldwide. BCG has long been administered to children in developing countries to guard against tuberculosis. But in a recent clinical trial, researchers at Harvard Medical School found the vaccine was also able to increase insulin production in patients with type 1 diabetes. Dr. Denise Faustman, the lead researcher, says the team was able to cure type 1 diabetes in...

Researchers at Case Western Reserve University School of Medicine have discovered a mutant form of the gene, Chk1, that when expressed in cancer cells, permanently stopped their proliferation and caused cell death without the addition of any chemotherapeutic drugs. This study illustrates an unprecedented finding, that artificially activating Chk1 alone is sufficient to kill cancer cells. "We have identified a new direction for cancer therapy and the new direction is leading us to a reduction in toxicity in cancer therapy, compared with chemotherapy or radiation therapy," said Dr. Zhang, assistant professor, Department of Pharmacology at the School of Medicine, and...

Medical care is going to get worse under Obamacare. Robert S. Dotson, M.D. tells us why: As income reductions are being imposed on private practice, costs are being driven up by exploding regulations. In addition, the plethora of new mandates and laws have increasingly criminalized every aspect of the practice of medicine and created vast new armies of armed bureaucrats whose sole aim is to impose civil and criminal penalties on any provider unlucky enough to be singled out for attention... New restrictions, rules, and regulations on healthcare – on providers and patients alike – have imposed legal constraints with...

Chemotherapy can undermine itself by causing a rogue response in healthy cells, which could explain why people become resistant, a study suggests. The treatment loses effectiveness for a significant number of patients with secondary cancers. Writing in Nature Medicine, US experts said chemo causes wound-healing cells around tumours to make a protein that helps the cancer resist treatment. A UK expert said the next step would be to find a way to block this effect. Around 90% of patients with solid cancers, such as breast, prostate, lung and colon, that spread - metastatic disease - develop resistance to chemotherapy. Treatment...

Cancer-busting chemotherapy can cause damage to healthy cells which triggers them to secrete a protein that sustains tumour growth and resistance to further treatment, a study said Sunday. Researchers in the United States made the "completely unexpected" finding while seeking to explain why cancer cells are so resilient inside the human body when they are easy to kill in the lab. They tested the effects of a type of chemotherapy on tissue collected from men with prostate cancer, and found "evidence of DNA damage" in healthy cells after treatment, the scientists wrote in Nature Medicine. http://ca.news.yahoo.com/chemotherapy-backfire-boost-cancer-growth-study-164516832.html

The two-step method to detect cyanide. (A) Adding a chemosensor to a blood sample, followed by extracting the purple chemosensor–cyano complex from the sample. (B) Washing the column with water The colour of cyanide poisoning is purple, according to researchers in Switzerland who have developed a method that enables them to quickly detect blood cyanide levels through a simple colour change. Cyanide poisoning as a result of smoke inhalation can have serious or fatal consequences unless an antidote is rapidly administered. Current methods for determining cyanide poisoning, including microdiffusion, microdistillation and liquid chromatography-mass spectrometry detection, can take up to an...

Results from a study conducted at Georgia State University suggest that a "fight" between bacteria normally living in the intestines and the immune system, kicked off by another type of bacteria, may be linked to two types of chronic disease. The study suggests that the "fight" continues after the instigator bacteria have been cleared by the body, according to Andrew Gewirtz, professor of biology at the GSU Center for Inflammation, Immunity and Infection. That fight can result in metabolic syndrome, an important factor in obesity, or inflammatory bowel disease (IBD). The results were published in the journal Cell Host &...

A seemingly small mistake in a paper in The New England Journal of Medicine (NEJM) landed a Danish physician-researcher in hot water last month after a German company threatened to sue him for potential losses that could run in the millions of dollars. The exchange prompted media consternation in Denmark over whether academic freedom was being censored, but the researcher, Anders Perner of Copenhagen University Hospital has corrected the error, which occurred in the publication of a study of a widely used drug to prevent shock, and thereby averted legal action. Still, the episode has shone a light on a...

While scientists hotly debate the existence of cancer stem cells, three related new studies, all conducted on mice, provide some supporting evidence. Stem cells are the foundation for healthy cell growth in the body. Some researchers believe that malignant stem cells also exist—so-called cancer stem cells that generate tumors and resist treatment by simply re-growing afterward. "Cancer stem cells are still controversial, but with progress in studies like these, it's less about whether they exist and more about 'what does this mean?'" said Dr. Max Wicha, director of the University of Michigan Comprehensive Cancer Center, who is familiar with the...

When I was a young doctor working in poor countries, I made a casual observation that old people in them did not seem to suffer very often from dementia. It occurred to me that properly conducted surveys, of the kind that I was not suited to performing, might be valuable, because a difference in the incidence and prevalence of dementia in various countries might offer a clue to the cause of the disease. As populations throughout the world age, this is a matter of increasing importance.But was my initial casual observation true? And, if true, might the explanation not be...

CNSNews.com) – Sixteen states have set a limit on the number of prescription drugs they will cover for Medicaid patients, according to Kaiser Health News. Seven of those states, according to Kaiser Health News, have enacted or tightened those limits in just the last two years. Medicaid is a federal program that is carried out in partnership with state governments. It forms an important element of President Barack Obama's health-care plan because under the Patient Protection and Affordable Care Act--AKA Obamcare--a larger number of people will be covered by Medicaid, as the income cap is raised for the program. With...

The International Olympic Committee decided not to include in the opening ceremony a moment of silence to honor the eleven Israeli athletes killed by Palestinian gunmen during the 1972 games in Munich. That move drew the ire of NBC’s Bob Costas. During Friday’s ceremony, he commented that, although a private moment of silence was held before a mere 100 people this week at the Athlete’s Village, “for many, tonight, with the world watching, is the true time and place to remember those who were lost and how and why they died.” Instead, the Olympic ceremony featured a weird, politically correct...
