Gene for AMD has now been identified by researchers

Age-related macular degeneration (AMD) is a debilitating eye disease affecting about 15 million people in the United States.

Evidence for a self-reinforcing "memory loop" - brain emotional center triggers the memory center

Researchers exploring the brain structures involved in recalling an emotional memory a year later have found evidence for a self-reinforcing "memory loop" - in which the brain's emotional center triggers the memory center, which in turn further enhances activity in the emotional center.

Pet scanning could cut use of angiograms and bypass surgery, as well as patient costs

Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves dollars, a study by a University at Buffalo team has shown.

Study finds potential link to help find blocked heart arteries

A blood test in combination with a stress test can help better determine if someone is likely to have a blocked heart artery, according to a study by doctors at Providence Hospital in Southfield, Mich.

Combining PET and CT scans leads to more accurate radiation therapy for lung cancer patients

Using Positron Emission Tomography in addition to Computed Tomography can reduce the amount of radiation exposure to normal tissue in some lung cancer patients

Confocal imaging promises early detection of skin cancer

Detecting skin cancer early saves lives, but is a job for specialists. A new European system based on confocal imaging promises to improve detection and diagnosis rates by 20 per cent and to speed up the whole process considerably.

PET and CT scans provides accurate detection and localization of foot infection in diabetic patients

Pioneering research with combined positron emission tomography (PET) and computed tomography (CT) scans provides accurate detection and localization of foot infection in diabetic patients, according to an article in the March issue of the Journal of Nuclear Medicine.

Beta-blockers can benefit patients with certain serious heart problems such as diastolic heart failure

Beta-blockers, medications that block the action of certain hormones on the heart, can benefit patients with certain serious heart problems such as diastolic heart failure, according to cardiologists at the Keck School of Medicine of the University of Southern California and Loma Linda University Medical Center.

Two important brain systems can influence an individual's behavior and emotional expression in times of need

The willingness to call out in distress to get help from others appears to be regulated by two brain systems with very different responsibilities, according to a study at the University of Wisconsin-Madison.

Autistic children shy from eye contact because they perceive even the most familiar face as an uncomfortable threat

The work deepens understanding of an autistic brain's function and may one day inform new treatment approaches and augment how teachers interact with their autistic students.

Freezing tumors is an effective way to treat a cancer patient's pain

The study, which appears in the March 2005 issue of the American Journal of Roentgenology, found that cryoablation relieved the pain of four patients who had very advanced disease.

Visual cortex contains neurons that are sensitive to viewing angle

Mistakes made by human subjects in identifying the facing direction of faces, cars or meaningless objects have yielded evidence that the brain contains nerve cells, or neurons, whose job is to encode the viewing angle of objects. It is well known that certain neurons respond to color, motion, edges and other aspects of our environment.

Abnormal brain structure tied to spatial, numerical thinking problems when children lack part of chromosome

Certain genetic diseases affect children's educational abilities in a distinctive pattern: impairing their numerical abilities more than their verbal skills. New research sheds light on this split in abilities by investigating how differences in brain structures may influence how the mind works.

CAD can effectively detect breast cancers

A computer-aided detection system (CAD) can effectively detect breast cancers a radiologist is more apt to initially miss, a new study shows.

Expected revolution in medicine, telemedicine, has simply not happened

Despite high expectations, telemedicine and telehealthcare systems, which enable doctors to interact with patients many miles away via video, digital imaging and electronic data transmission, have had only limited impact on the National Health Service, according to a study sponsored by the ESRC.

MRI better than current standard of practice in assessing neoadjuvant chemotherapy in breast cancer patients

More breast cancer patients with large palpable tumors are now undergoing chemotherapy before surgery in an effort to reduce the size of their tumor, and MRI is the best way to predict if the chemotherapy is working, preliminary results of a study show. If the chemotherapy is successful, then the woman may be able to undergo breast-conservation surgery rather than a mastectomy.

The impact of cruciate ligament rupture on osteoarthritis of the knee

Study links tears of anterior cruciate ligament to increased risk and severity of disease even among patients with no recall of significant knee injury.

Radiopharmaceuticals and lasers produce sound to treat and detect cancerous moles

When treating skin cancer, differentiating between melanoma and healthy moles can be difficult. Doctors must know the shape of the cancer and how deep it is before treating the problem. Now, a skin care specialist at the University of Missouri-Columbia has teamed with MU engineering and internal medicine professors to develop a better identification and treatment process.

Exercise tolerance, good screening test for chest pain patients

Mayo Clinic researchers studying patients in the emergency department with acute chest pain report in the current issue of Mayo Clinic Proceedings that exercise treadmill testing (ETT) was often sufficient for evaluation.

Children can benefit from surgery for sleep apnea

Times have changed. Within the last ten years, the primary reason that children have had surgery to remove their tonsils and adenoids is not because of infection. Instead, up to 90 percent of the adenotonsillectomy surgeries are to correct obstructive sleep apnea (OSA).
