Whole-body-vibration does not effectively boost bone density

Whole-body-vibration, a popular exercise which uses a vibrating platform, is sometimes advertised as being able to boost bone density. However, a one-year-study on healthy postmenopausal women has shown that it has no such effect.

New project to identify what gives biosonar the edge over human-made technologies

Sonar and ultrasound, which use sound as a navigational device and to paint accurate pictures of an environment, are the basis of countless technologies, including medical ultrasound machines and submarine navigation systems. But when it comes to more accurate sonar and ultrasound, animals' "biosonar" capabilities still have the human race beat.

Functional MRI illuminates brain networks activated by motion

An estimated 300,000 people in North America are afflicted with dystonia, a disorder characterized by a progressive loss of motor control. Patients with generalized dystonia grapple with involuntary muscle spasms that lead to uncontrolled twisting and turning in awkward, sometimes painful postures.

Harrison Medical Center installs three Toshiba Infinix-i vascular X-ray systems

Performing cardiac catheterizations through the radial artery is proven to make exams safer for patients while frequently reducing post-procedure hospital stay times. To conduct radial interventions from both the right and left side, Harrison Medical Center in Bremerton, Wash., installed three Infinix™-i vascular X-ray systems from Toshiba America Medical Systems, Inc.

Luminescent upconversion nanocrystals can detect cancer cells

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Opaque tissues can be turned into glassy, transparent substances by using these biomarkers which rely on near-infrared excitation.

Study uses fMRI to assess changes in brain after exercise intervention

Areas of the brain responsible for pain processing and cognitive performance changed in fibromyalgia patients who exercised following a medication holiday, say researchers from Georgetown University Medical Center. They say the changes indicate brain functioning is more streamlined after an exercise intervention because less of the brain-s resources is devoted to processing bothersome fibromyalgia perceptions such as pain.

Study: Primary visual cortex is modulated only by attention

In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the rinumber of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally different processes and not necessarily connected.ght side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors.

Vegetative patients could be contacted using simple, cheap and portable technique – EEG

Scientists from the UK and Belgium have found a way to communicate with brain damaged patients who appear to be in a vegetative state. Writing in The Lancet medical journal they describe how they measured electrical activity in the brain to detect consciousness. The technique, known as EEG or electroencephalogram, is painless and involves attaching electrodes to the head.

Simple portable test can diagnose 'vegetative' patients with consciousness

The Coma Science Group, led by Dr Steven Laureys, has developed, along with its partners in London, Ontario, (Canada) and Cambridge (England), a portable test which will permit a simpler and less expensive diagnosis of 'vegetative' patients who still have consciousness, despite the fact that they do not have the means to express it.
