Two-photon absorption imaging of hemoglobin

In an advance that can potentially assist cancer diagnosis, a new optical technique provides high-resolution, three-dimensional images of blood vessels by taking advantage of the natural multiple-photon-absorbing properties of hemoglobin, the red-blood-cell molecule that carries oxygen throughout the bloodstream.

Gold nanoparticles for early detection of cancer

By attaching gold nanoparticles - like tiny balls or rods- to cancer cells, earlier detection will be possible.

New combined imaging promises insights into multiple sclerosis

Researchers have developed a way to use three types of microscopic imaging techniques simultaneously to analyze living tissue and learn more about the molecular mechanisms of multiple sclerosis, information that could help lead to earlier detection and new treatments.

Autistic children can interpret the mental state of others by looking at their eyes

In findings that contradict previous studies, psychologists found that autistic children can 'read' a stranger's mental state based on that person's eyes. Autistic children have long been thought to be poor at interpreting people's mental states based on facial expressions, especially expressions around the eyes.

Targeted nanoparticles image early tumors

A well-established fact in cancer therapy is that early tumor detection improves the odds that a patient will survive the disease. Now, using nanoparticles targeted to the tiny blood vessels that surround even the smallest tumors, researchers at the Siteman Center for Cancer Nanotechnology Excellence (CCNE) have developed a radioactive imaging agent that was able to identify human tumors in rabbits.

Hope for pancreatic cancer survivors

A new study shows that pancreatic cancer patients 65 or older who live at least five years after surgery have nearly as good a chance as anyone else to live another five years.

High dopamine transporter levels not linked to attention-deficit hyperactivity disorder

Results from a brain-imaging study conducted at the U.S. Department of Energy's Brookhaven National Laboratory in collaboration with Mount Sinai School of Medicine in New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease.

Shaped-beam radiosurgery treats tiniest lung tumors

Patients with metastatic cancer tumors in their lungs are much more likely to live disease-free if they have an experimental treatment involving shaped-beam radiosurgery rather that conventional treatment, according to a University of Rochester Medical Center study.

MRI technology breaks new ground in molecular imaging

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for magnetic resonance imaging (MRI) that allows for detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques.

Remote-control software that enables off-site MRI imaging via the Internet

UCLA radiologists and Siemens Medical Solutions have developed remote-control software that enables an off-site imaging expert to operate a magnetic resonance imaging (MRI) machine via the Internet.

Gene called Kibra plays an important role in memory

Researchers at the Translational Genomics Research Institute (TGen) have announced the discovery of a gene that plays a significant role in memory performance in humans.

Cocaine addicts have an altered perception of reward

People addicted to cocaine have an impaired ability to perceive rewards and exercise control due to disruptions in the brain's reward and control circuits, according to a series of brain-mapping studies and neuropsychological tests conducted at the U.S. Department of Energy's Brookhaven National Laboratory.

Research implicates brain circuits involved in drug craving and emotional response to food

Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have found new clues to how the brain and the stomach interact with emotions to cause overeating and obesity.

Dual-mode nanoscale imaging yields new details of cellular events

To create drugs capable of targeting malignancies, scientists must first decode exactly how a cell or a group of cells communicates with other cells and reacts to a broad spectrum of complex biomolecules surrounding it.

Boston Life Sciences announces issuance of U.S. patent for methods to diagnose ADHD

Boston Life Sciences has announced that the U.S. Patent and Trademark Office has issued a patent to the President and Fellows of Harvard College, the General Hospital Corporation and Organix that covers methods of diagnosing and monitoring attention deficit hyperactivity disorder (ADHD) by assessing the level of dopamine transporter (DAT) in at least one region of a patient's central nervous system.
