What are the long term effects of auto-immunity (auto inflammation) on longevity?
In a new study from Brigham and Women’s Hospital, in collaboration with the National Cancer Institute, researchers have quantified how many years of life are gained by being physically active at different levels, among all individuals as well as among various groups with different body mass index.

The new research shows that tumors can in fact have their origins in several types of differentiated cells in the central nervous system, including neural stem cells, astrocytes (a sub-type of glial cell) and even neurons, when cancer-causing genes are introduced. Neurons do not divide, but when the genes were introduced they were found to transform into stem cells that could reproduce rapidly.
A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes.
The recommended daily intake is 11 mgs for adults, though aging adults don’t often absorb zinc well. Taking anything over 40 mgs each day can lead to problems.
Yes, it is true. And it is due to the pesticides and insecticides we put on our soil. Shame on us for continuing such an idiotic practice. Two alternatives are suggested:
1) cook your rice the traditional Asian way with 6 cups water to 1 cup rice. You loose nutrients to the water this way, but you also lose about 30% of the arsenic in the hull of brown rice.
2) eat quinoa
Researchers have created one drug that is 10 times more potent than current cancer-fighting drugs. The technology could be used to address other problems such as migraine headaches or Alzheimer’s.
They took an existing drug, and enhanced it. It is promising.
This study is the first-of-its-kind to show an association between insufficient sleep and biologically more aggressive tumors as well as likelihood of cancer recurrence.
via Lack of sleep found to be a new risk factor for aggressive breast cancers.
In cancer cells, normal mechanisms governing the cellular life cycle have gone haywire. Cancer cells continue to divide indefinitely, without ever dying off, thus creating rapidly growing tumors. Swiss scientists have discovered a protein complex involved this deregulated process, and hope to be able to exploit it to stop tumor formation in its tracks.
A cleaner planet equals a cleaner human.
Women who exercised either during their reproductive or postmenopausal years had a reduced risk of developing breast cancer. Women who exercised 10 to 19 hours per week experienced the greatest benefit with an approximate 30 percent reduced risk. Risk reductions were observed at all levels of intensity, and exercise seemed to reduce the risk of hormone receptor positive breast cancers, the most commonly diagnosed tumor type among American women.
“The observation of a reduced risk of breast cancer for women who engaged in exercise after menopause is particularly encouraging given the late age of onset for breast cancer,” McCullough said.
When the researchers looked at the joint effects of physical activity, weight gain and body size, they found that even active women who gained a significant amount of weight – particularly after menopause – had an increased risk of developing breast cancer, indicating that weight gain can eliminate the beneficial effects of exercise on breast cancer risk.
One in three cancers diagnosed around the world are skin cancers. In the USA, 1 in 5 Americans will get skin cancer at some point in their lives.
There are two types of skin cancers:
1) melanomas, which form deep in the cells that generate skin pigment, and
2) non-melanoma cancers, like basal cell carcinoma and squamous cell carcinoma
This patch treats basal cell carcinoma, specifically. It killed the cancer in 80% of all patients, although the sampling was pretty small (10 patients, all of whom were tested at 3 years after treatment).
In this study, a total of 10 patients between the ages of 32 and 74 years with facial basal cell carcinoma were treated with custom-made and fully sealed P-32 patches. Subjects had lesions near the eyes, the nose and the forehead, and all were treated locally with the P-32 patch for three hours on an outpatient basis. The custom patches were reapplied on the fourth and seventh days after the first treatment for another three hours each, delivering a fragmented dose of 100 Gy (a measurement of radiation exposure) to the cancerous lesions only—without harming deeper structures or other areas of healthy skin on the face. Biopsies were taken at three months and repeated within the three years that followed treatment, and eight out of 10 patients were found to be entirely cured and cancer free.
Previous studies have linked the sleep disordered breathing (SBD) problems to hypertension, cardiovascular disease, depression and earlier death, but this is the first to find a link to cancer.
Lead author Dr. F. Javier Nieto, chair of the Department of Population Health Sciences at the University of Wisconsin School of Medicine and Public Health commented that the study had subjects with severe SBD had five times higher incidence of cancer deaths, more than just a statistical anomaly. Previous studies in animals have shown similar results, while other studies have linked cancer to possible lack of oxygen or anaerobic cell activity over long periods of time, therefore, it’s possible poor breathing fails to oxygenate the cells sufficiently.
Dr. Nieto, an expert in sleep epidemiology continued:
“Clearly, there is a correlation, and we are a long way from proving that sleep apnea causes cancer or contributes to its growth … But animal studies have shown that the intermittent hypoxia (an inadequate supply of oxygen) that characterizes sleep apnea promotes angiogenesis-increased vascular growth – and tumor growth. Our results suggest that SDB is also associated with an increased risk of cancer mortality in humans.”
