COLUMBUS, Ohio – Researchers who have been working for nearly a decade to piece together the process by which an enzyme repairs sun-damaged DNA have finally witnessed the entire process in full detail in the laboratory.
What they saw contradicts fundamental notions of how key biological molecules break up during the repair of sunburn – and that knowledge could someday lead to drugs or even lotions that could heal sunburn in humans. (more…)
GAINESVILLE, Fla. — Few treatments exist for patients with advanced primary liver cancer, but University of Florida researchers have found a new way to broaden the range of options and potentially improve health outcomes by combining two treatments.
In the first study of its kind, the researchers combined sorafenib, the only Food and Drug Administration-approved pill for treating advanced liver cancer, with another routinely used therapy known as transarterial chemoembolization, which works by cutting off the blood supply to tumors. No unexpected toxic effects were seen, and the combo appears to have the potential to improve survival for certain groups of patients. (more…)
Do smarter people live longer and better lives? Are certain personality types more prone to premature death than are others? As our population continues to age in dramatic numbers, these questions become increasingly relevant. A new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, provides an overview of research on possible associations between intelligence and personality traits and various health outcomes.
Although there is not much evidence to date that links intelligence with cancer, low intelligence has been shown to be related to increased risk of hospital admission and death due to cardiovascular disease. In addition, lower intelligence is associated with a greater incidence of accidents and risk of death by homicide than is higher intelligence.(more…)
*Analysis questions U.S. Task Force recommendations for every-other-year screening starting at age 50*
ANN ARBOR, Mich. — A new study questions the controversial U.S. Preventative Service Task Force recommendations for breast cancerscreening, with data that shows starting at a younger age and screening more frequently will result in more lives saved.
The study analyzed the same data looked at by the task force, which issued its guidelines on mammography screening in November 2009. The study authors compared the task force’s recommendations for screening every other year in women 50-74 to American Cancer Society guidelines of screening every year in women 40-84.(more…)
Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.
Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body’s sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG. (more…)
A study by Newcastle University in Britain, indicates that green tea may protect the brain from diseases such as Alzheimer’s and other types of dementia. The research, published in the journal Phytomedicine, also suggests that the ancient Chinese remedy that has been popularized throughout the world may also have an important role in protecting the body against cancer.
In the study, scientists investigated whether the beneficial properties of green tea, which had already been proven in newly prepared and undigested tea, were still active once the tea was digested. (more…)
Zen meditation has many health benefits, including a reduced sensitivity to pain. According to new research from the Université de Montréal, meditators do feel pain but they simply don’t dwell on it as much. These findings, published in the month’s issue of Pain, may have implications for chronic pain sufferers, such as those with arthritis, back pain or cancer.
“Our previous research found that Zen meditators have lower pain sensitivity. The aim of the current study was to determine how they are achieving this,” says senior author Pierre Rainville, researcher at the Université de Montréal and the Institut universitaire de gériatrie de Montréal. “Using functional magnetic resonance imaging, we demonstrated that although the meditators were aware of the pain, this sensation wasn’t processed in the part of their brains responsible for appraisal, reasoning or memory formation. We think that they feel the sensations, but cut the process short, refraining from interpretation or labelling of the stimuli as painful.” (more…)
Aspirin - to fight cancer. Image credit: Volker Mintzlaff
Or does it? Fresh research from Oxford University seems to reveal that a low dose of aspirin taken over a substantial period of time produces promising results, indicating that the death rates of many types of cancer reduce greatly. In fact, the evidence presented is staggering and if true, would be a medical breakthrough of exponential proportions.
Let us be optimistic, for cancer is a disease which has cut across most families around the globe. Few of us have not lost a grandparent, parent, uncle or aunt to this disease, in some cases even brothers, or worse still, nephews or nieces…or worse still, sons or daughters, grandsons and daughters. Now it seems there is good news which does not involve chemo-therapy or radio-therapy, which create many success stories but also many victims. (more…)
