Transcutaneous Electrical Nerve Stimulato

by

A Transcutaneous Electrical Nerve Stimulator, more commonly referred to as a TENS unit is an electronic device that produces electrical signals used to stimulate nerves. he current may be delivered intermittently. The mild electrical current generates heat that serves to relieve stiffness, improve mobility, and relieve pain. The treatment is believed to stimulate the body’s production of endorphins or natural pain killers. TENS units are sometimes used in an attempt to alleviate neuropathic pain. Although results are modest, some patients benefit from this approach. However, a study published in the New England Journal of Medicine found that TENS therapy was no more effective against chronic lower back pain than a placebo.

New Treatment Suitable For All Patients With Least Treatable Brain Tumors, Study Suggests

by

New research at Wake Forest University Baptist Medical Center suggests that a three-drug cocktail may one day improve outcomes in patients with glioblastoma multiforme (GBM), a type of brain tumor with a dismal prognosis. Two of the drug candidates have been developed, and the team is working on the third — all targeted to kill or impair cancer cells and spare healthy brain.Waldemar Debinski, M.D., Ph.D., senior researcher and director of the Wake Forest Brain Tumor Center of Excellence, predicts that the cocktail could be tested in patients within five years. The treatment would be based on the first-ever documented “molecular signature” of GBM tumors. The researchers had previously reported that three different proteins are found in high levels individually in these cancers. In the current study, reported in Clinical Cancer Research, they examined 76 specimens of brain tumor, including … Read more

Growing Artificial Skin From Hair Roots

by

here is new hope for patients with chronic wounds: euroderm GmbH and the Fraunhofer Institute for Cell Therapy and Immunology IZI in Leipzig have been granted approval to produce artificial skin from patients’ own cells.It sounds like something from a science fiction novel: Pluck a few of someone’s hairs, and four to six weeks later they have grown into a piece of skin. Of course, what researchers at the Fraunhofer Institute for Cell Therapy and Immunology IZI in Leipzig have recently started doing in their new cleanrooms isn’t quite as simple as that. “We and euroderm GmbH have been given permission to grow dermal tissue for grafting onto chronic wounds such as open leg ulcers on diabetics patients,” says IZI team leader Dr. Gerno Schmiedeknecht. At present, chronic wounds are treated by grafting on the patients’ own skin, which is … Read more

Sublimenal Messages

by

Flag waving is a metaphor for stirring up the public towards adopting a more nationalistic, generally hard-line stance. Indeed, “rally ’round the flag” is a venerable expression of this phenomenon. It comes as some surprise, then, that studies conducted by researchers at the Hebrew University of Jerusalem have shown that exposing people to a subliminal image of the national flag had just the opposite fact — moderating their political attitudes. Further, the researchers say that their studies indicate that, in general, subliminal messages — that is, messages that are processed by our brains but never reach our consciousness — do indeed influence explicit attitudes and real-life political behavior, a significant extension to what we know about the effects of non-conscious processes. The studies, led by cognitive scientist Dr. Ran Hassin of the Hebrew University of Jerusalem Psychology Department, show that … Read more

Is ESP Real?

by

Psychologists at Harvard University have developed a new method to study extrasensory perception that, they argue, can resolve the century-old debate over its existence. According to the authors, their study not only illustrates a new method for studying such phenomena, but also provides the strongest evidence yet obtained against the existence of extrasensory perception, or ESP. The research was led by Samuel Moulton, a graduate student in the department of psychology in the Faculty of Arts and Sciences at Harvard University with Stephen Kosslyn, John Lindsley Professor of Psychology at Harvard and was published in the Jan. 2008 issue of the Journal of Cognitive Neuroscience. The scientists used brain scanning to test whether individuals have knowledge that cannot be explained through normal perceptual processing. “If any ESP processes exist, then participants’ brains should respond differently to ESP and non-ESP stimuli,” … Read more
