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.

Repeated heading of a soccer ball increases risk for brain injury, cognitive impairment

Using advanced imaging techniques and cognitive tests, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center , the University Hospital and academic medical center for Einstein, have shown that repeatedly heading a soccer ball increases the risk for brain injury and cognitive impairment.

Alzheimer’s disease progression and body weight may be linked: Study

There have been studies that show that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight. However some studies also show that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI).

Study examines link between early-stage Alzheimer's and lower BMI

Studies have shown that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight, yet researchers have also found that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI). A current study examines this relationship between Alzheimer's disease and BMI.

Kessler Foundation neuropsychologists receive National Multiple Sclerosis Society grants

Two neuropsychologists at Kessler Foundation Research Center were awarded more than $100,000 in grants by the National Multiple Sclerosis Society. Nancy Chiaravalloti, PhD, received $63,000 to conduct a pilot study, "Speed of Processing Training for Improving Processing Speed in Persons with MS".

Impulsive men have lower levels of GABA in dorsolateral prefrontal cortex

Impulsive individuals tend to display aggressive behavior and have challenges ranging from drug and alcohol abuse, to problem gambling and difficult relationships. They are less able to adapt to different social situations. Impulsivity is also a common feature of psychiatric disorders.

Potential drug therapy for Hutchinson Gilford Progeria Syndrome

Researchers have identified a potential drug therapy for a premature ageing disease that affects children causing them to age up to eight times as fast as the usual rate.

UC Davis, UCSF seek to predict and prevent osteoarthritis in young people

How people walk, jump and run and how their knees look in an MRI scanner may hold the secret to predicting years or even decades in advance whether they will develop osteoarthritis, the common degenerative joint disease that strikes half of all Americans by the time they reach the age of 70.
