Successful aneurysm treatment may not improve quality of life

Patients with unruptured brain aneurysms have significant reductions in several areas of quality of life—especially physical functioning, reports a study in the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Number of kidney cancer cases rises over 9,000 in Great Britain

The number of cases of kidney cancer diagnosed each year in Great Britain has risen over 9,000 for the first time, new figures from Cancer Research UK show today.

Western University develops DeskCAT- Multi-slice CT Scanner

Biophysics professors at Western University, in London, Canada, have developed a CT (Computed Tomography) scanner small enough to sit on a desk. Jerry Battista, Chair of the Department of Medical Biophysics at the Schulich School of Medicine & Dentistry and Kevin Jordan of the London Regional Cancer Program at London Health Sciences Centre invented the DeskCAT- Multi-slice CT Scanner as a novel and interactive way to teach CT imaging techniques to a wide range of students.

New ultrasound technique for rapid and accurate assessment of osteoporosis

Laser-based measurements are proving to be a promising method for the assessment of osteoporosis. The team led by Professor Jussi Timonen has developed an ultrasound technique that use laser beams for a rapid and accurate assessment of osteoporosis.

Concussion in kids may lead to memory and cognitive problems at school later in life

The researchers from Nationwide Children’s Hospital and The Ohio State University looked at 186 children aged 8 to 15 who experienced concussion - most commonly in a fall or while playing sports - or other brain injury from a car accident or other causes. The children’s parents were asked to fill out a standard questionnaire to assess their child’s cognitive and physical status before the concussion, and again two weeks, three months and a year later. These responses were compared to those from parents of 99 similar children who came into the emergency room with orthopedic injuries.

New tool to map extent of traumatic brain injury

Traumatic brain injury among soldiers, sportsmen and women and accident survivors are common but may go undetected at the time of the event and manifest later in life. Now scientists are testing a tool that lights up the breaks these injuries leave deep in the brain's wiring, much like X-rays show broken bones.

Researchers refute widely accepted hypothesis about causative step in ALS

In science, refuting a hypothesis can be as significant as proving one, all the more so in research aimed at elucidating how diseases proceed with a view toward preventing, treating, or curing them. Such a discovery can save scientists from spending precious years of effort exploring a dead end. In a study published in the Proceedings of the National Academy of Sciences, Munich-based researchers refute a widely accepted hypothesis about a causative step in neurodegenerative conditions.

Helmholtz Association grant for research on diseases caused by protein misfolding

Professor Erich Wanker of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch and of the Excellence Cluster Neurocure is to receive EUR 675 000 in funding from the Helmholtz Association over the next two years. The grant shall be used to accelerate the search for active agents to treat diseases that are caused by protein misfolding. These include Alzheimer's and Parkinson's.

Major discovery for visual cognition using diffusion spectrum imaging

If you are looking for a particular object - say a yellow pencil - on a cluttered desk, how does your brain work to visually locate it?

Deep brain stimulation can also affect respiratory function

Deep brain stimulation (DBS) has become a common treatment for patients with chronic pain or movement disorders. Now a unique set of experiments shows that electrical stimulation in some of the same brain areas can also affect respiratory function, according to a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Diffusion-weighted MRI may effectively indicate response to ovarian cancer treatment

Cancer Research UK-funded scientists have determined that a magnetic resonance imaging (MRI) technique, which measures the movement of water molecules within the tumour, may be the best way to monitor how women with late-stage ovarian cancer are responding to treatment. The study is published in the journal Radiology today.

Researchers reveal how molecular imaging can solve breast cancer mysteries

In two new studies featured in the February issue of the Journal of Nuclear Medicine, researchers are revealing how molecular imaging can be used to solve mysteries about difficult cases of breast cancer.

Treatment with clot-busting drugs safe for patients with wake-up stroke

Clot-busting drugs may be safe for patients who wake up experiencing stroke symptoms, according to preliminary research presented at the American Stroke Association's International Stroke Conference 2012.

Size of a man's prostate gland may determine severity of cancer

The size of a man's prostate gland may help predict the severity of cancer, with a smaller prostate being more likely to harbor serious disease.

UH vision scientist hopes techniques lead to earlier diagnoses in glaucoma

A University of Houston (UH) vision scientist has received a $1.85 million grant from the National Institutes of Health (NIH) to investigate whether his techniques are more effective than others in understanding the earliest changes of glaucoma, which could lead to developing a way to earlier diagnose this potentially blinding disease.

New initiative to detect cancers in earliest stages inside cells

A team of cancer imaging experts at Johns Hopkins has embarked on a five-year research initiative to speed development of early diagnostic tests and new treatments for breast, prostate and other common cancers.

Handheld near-infrared imaging device enables quick detection of hematomas

When accidents that involve traumatic brain injuries occur, a speedy diagnosis followed by the proper treatment can mean the difference between life and death. A research team, led by Jason D. Riley in the Section on Analytical and Functional Biophotonics at the U.S. National Institutes of Health, has created a handheld device capable of quickly detecting brain injuries such as hematomas, which occur when blood vessels become damaged and blood seeps out into surrounding tissues where it can cause significant and dangerous swelling.

Modern humans have a better sense of smell than Neanderthals

Compared to Neanderthals, modern humans have a better sense of smell. Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain organization.

Synthetic human tissue aids in testing photoacoustic and ultrasonic imaging technologies

The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies.

Study finds structure-function impairments in people addicted to cocaine

The more gray matter you have in the decision-making, thought-processing part of your brain, the better your ability to evaluate rewards and consequences. That may seem like an obvious conclusion, but a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory is the first to show this link between structure and function in healthy people - and the impairment of both structure and function in people addicted to cocaine.
