UJI's current research study on early detection of Alzheimer's Disease using fMRI

The Universitat Jaume I (UJI) of Castelló is working on the early detection of Alzheimer's Disease by using functional magnetic resonance imaging (fMRI) techniques. The study is being carried out within the framework of a national project called MIND, which approaches Alzheimer's disease from a multidisciplinary perspective and involves twelve biomedicine companies and the corresponding public research organisations associated with them.

Cardiac MRI exams gain prominence in the medical imaging market

Developments in imaging technology and software continue to help cardiac MRI exams gain prominence in the medical imaging market by meeting the demand for faster scan times and the ability to view areas of the body that were previously deemed impossible to image, according to "Medical Imaging Markets: MRI (Magnetic Resonance Imaging) and Ultrasound" by healthcare market research firm Kalorama Information.

Mechanism during sleep responsible for memory formation identified

A Rutgers University, Newark and Coll-ge de France, Paris research team has pinpointed for the first time the mechanism that takes place during sleep that causes learning and memory formation to occur.

Carotid and cardiac procedures result in higher incidence of post-operative strokes

Among patients undergoing cardiac surgery, post-operative stroke occurred in approximately 2 percent, was not correlated with significant carotid artery narrowing, but was more common among patients who had combined cardiac and carotid procedures, according to a report in the September issue of Archives of Neurology, one of the JAMA/Archives journals.

Clinical study paper on TMR therapy with autologous stem cells presented

PLC Systems Inc., a company focused on innovative cardiac and vascular medical device-based technologies, today announced that a paper on a clinical study utilizing its Transmyocardial Laser Revascularization (TMR) therapy in conjunction with autologous stem cells was presented at ESC Congress 2009, the annual meeting of the European Society of Cardiology, in Barcelona, Spain.

Monoamine oxidases responsible for personality and behaviour

Antisocial and aggressive behaviours represent a widespread and expensive social problem. Recent research has convincingly shown that there is a strong interaction between genetic inheritance and environment for development of personality and behaviour.

Human neural stem cells to treat Pelizaeus-Merzbacher Disease

StemCells, Inc. (NASDAQ:STEM) announced today that it will soon initiate with the University of California, San Francisco (UCSF) Children’s Hospital a Phase I clinical trial to evaluate the therapeutic potential of StemCells’ proprietary HuCNS-SC® product candidate (purified human neural stem cells) to treat Pelizaeus-Merzbacher Disease (PMD), a myelination disorder that primarily affects infants and young children.

Researchers study the brain activity using magnetic resonance imaging

A woman looks familiar, but you can't remember her name or where you met her. New research by UC Irvine neuroscientists suggests the memory exists - you simply can't retrieve it.

Early schizophrenia symptoms include unusually high CA1 subfield activity

In the first functional magnetic resonance imaging (fMRI) study of its kind, neurologists and psychiatrists at Columbia University have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders.

Specific targeting of brain tumors with an optical/magnetic resonance imaging nanoprobe across the blood-brain barrier

Earlier this year, researchers at the University of Washington reported that they had developed a toxin-nanoparticle combination that inhibits brain cancer invasion when added to tumor cells growing in culture.

Brain profiling tool to detect at-risk combat soldiers

According to a recent Washington Post study, approximately 20% of U.S. soldiers returning from Iraq and Afghanistan are psychologically damaged. Among them are a substantial number with post-traumatic stress disorder (PTSD), and the high rate of suicide among PTSD sufferers has become unacceptable to Army commanders and the soldiers' families.

Rapid progression of multiple sclerosis linked to smoking

Patients with multiple sclerosis who smoke appear to experience a more rapid progression of their disease, according to a report in the July issue of Archives of Neurology, one of the JAMA/Archives journals.

New findings on molecular imaging and prostate cancer

A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed.

New method found for the diagnosis of cartilage disease

In its quest to find new strategies to treat osteoarthritis and other diseases, a Boston University-led research team has reported finding a new computer tomography contrast agent for visualizing the special distributions of glycosaminoglycans (GAGs) - the anionic sugars that account for the strength of joint cartilage.

Caltech neuroscientists emphasize on the neural mechanisms involved in social behaviour

In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space.

Astrocytes play a key role in the generation of fMRI signals

Functional magnetic resonance imaging (fMRI) is a technique widely used in studying the human brain. However, it has long been unclear exactly how fMRI signals are generated at brain cell level. This information is crucially important to interpreting these imaging signals. Scientists from the Academy of Finland's Neuroscience Research Programme (NEURO) have discovered that astrocytes, support cells in brain tissue, play a key role in the generation of fMRI signals.

Research finds that people with psoriasis are less likely to react to looks of disgust by others

People with psoriasis - an often distressing dermatological condition that causes lesions and red scaly patches on the skin - are less likely to react to looks of disgust by others than people without the condition, new research has found.

Adolescents engaged in dangerous activities are associated with increased brain maturity

A new study using brain imaging to study teen behavior indicates that adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.

Toshiba America Medical Systems installs its 800th Vantage 1.5T MR system

Toshiba America Medical Systems, Inc., an industry leader in magnetic resonance (MR) technology, reached a significant achievement in installing its 800th Vantage 1.5T MR system at Elkview General Hospital in Hobart, Okla. Elkview is using the Vantage system for orthopedic, neuro and abdominal imaging.

New minimally invasive surgery techniques and instruments reduce tissue damage and infection

New, delicate surgery techniques to hunt for tumours could benefit from a lighter touch - but from a robot, rather than from a human hand. Canadian researchers have created a touchy-feely robot that detects tougher tumour tissue in half the time, and with 40% more accuracy than a human. The technique also minimises tissue damage.
