SPECT imaging may lead to early diagnosis of Alzheimer's

Alzheimer's disease (AD) currently afflicts approximately 4.5 million Americans. One of the most feared diseases of old age, AD robs its victims of their memories and personalities long before it takes their lives.

Gene therapy helps alcoholic rats

As a follow up to previous work showing that gene therapy can reduce drinking in rats trained to prefer alcohol, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have used the same technique to cut drinking in rats with a genetic predisposition for heavy alcohol consumption.

Chemical thumbprint can help determine if tumor is returning or dying

Brain tumor survivors live with the constant worry that their cancer might come back. And even if they have a brain scan every few months to check, doctors often can't tell the difference between new cancer growth and tissue changes related to their treatment with radiation or chemotherapy.

New electromagnetic imaging techniques to help detect breast abnormalities

Researchers are testing three promising new electromagnetic imaging techniques to help detect breast abnormalities, including cancer. The findings of the benchmark study will be published in the May issue of the journal Radiology.

Combination of real-time PET and CT is a highly sensitive tool for identifying non-small cell lung cancer

The combination of real-time PET and CT is a highly sensitive tool for identifying non-small cell lung cancer (NSCLC) and can assist in identifying patients whose cancer has not yet spread to lymph nodes, according to results of a study by researchers at Johns Hopkins.

First imaging-based diagnostic test for living Alzheimer’s

Mayo Clinic researchers have devised a way to produce enhanced MRI (magnetic resonance imaging) pictures of the destructive brain lesions that cause Alzheimer’s disease. This advance using laboratory mice lays the foundation for the first imaging-based diagnostic test for living Alzheimer’s disease patients.

Gene therapy may delay Alzheimer progression

Results from a preliminary eight-patient study of gene therapy for Alzheimer’s disease are positive enough to justify a larger clinical trial, Mark H. Tuszynski, M.D., Ph.D., reported April 27 at the 56th Annual Meeting of the American Academy of Neurology. Dr. Tuszynski says that a larger trial is being planned at a major medical center in Chicago.

A burst of brain energy depends more on a unique molecular cycle than on blood flow variation

A century old mystery is taking place in your head as you read these words. Blood vessels in regions of your brain are widening, bathing cells in an increased blood flow.

PET imaging has recently been shown to aid in the diagnosis of particular neurological syndromes associated with cancer

PET imaging has been shown to improve detection of a variety of cancers, and earlier tests have suggested this technique may be useful in identifying small tumors in patients with paraneoplastic neurological disorders. But PET imaging is not yet widely available, and clear indicators of clinically meaningful outcomes using PET are essential to warrant use with this patient population.

Results look promising in Alzheimer’s gene therapy trial

Surgical placement of genetically modified tissue directly into the brains of patients with Alzheimer’s disease, an experimental approach to delaying brain cell loss associated with the disease, leads to increased metabolic activity in the brain, with cells apparently responding to the insertion of growth factor-producing grafts

Serono says Rebif an effective treatment for brain lesions

New long-term data support the importance of early treatment with high dose, high frequency Rebif® (interferon beta-1a) 44 mcg in reducing the long-term accumulation of brain lesion volume in patients with relapsing remitting multiple sclerosis (MS).

Improvement of Parkinson’s disease symptoms when neurorestorative molecule pumped to the center of the brain

A recent study has shown clinical improvement of Parkinson’s disease symptoms after long-term infusion of a neurorestorative molecule, pumped directly to the center of the brain. The study will be presented at the American Academy of Neurology 56th Annual Meeting in San Francisco, Calif., April 24 – May 1, 2004.

Researchers show that language “center” of brain shifts with age

Along with left- or right-handedness, the hemisphere of the brain where language capacity resides is likely predetermined. Researchers have now shown that with age, language capacity in the brain becomes more evenly distributed between hemispheres.

Injections of adult stem cells could repair hearts

Injections of adult stem cells into damaged heart tissue significantly improved heart function in patients with severe congestive heart failure, according to results of the first prospective randomized trial of the experimental therapy presented today at the American Association for Thoracic Surgery.

Severe Acute Respiratory Syndrome (SARS) overview

Severe Acute Respiratory Syndrome (SARS) is an atypical form of pneumonia that first appeared in November 2002 in Guangdong Province, China.

The April 2004 issue of Otolaryngology focuses on head and neck surgery

The efficacy of a new cancer-fighting virus is tested in the study, “Treatment of Solid Sarcomas in Immunocompetent Mice with Novel Oncolytic Herpes Simplex Viruses.” A team of multi-disciplinary Japanese researchers found that a weakened version of herpes simplex virus (HSV) effectively eradicated neck and flank tumors in mice.

Marker predicts patients who are seven times more likely to die after suffering a heart attack

Researchers at Brigham and Women’s Hospital (BWH) have found a protein in the blood that may one day produce a simple and inexpensive test to help determine who is at high risk for problems following a heart attack.

FDA recommends approval of stenting to prevent stroke

Cordis Endovascular today reported the Circulatory System Devices Panel of the U.S. Food and Drug Administration (FDA) recommended approval of the company's new Cordis Carotid System. Cordis Endovascular is a division of Cordis Corporation, a Johnson & Johnson company.

Scientist discovers why skin turns leathery

“The reason our skin becomes more leathery and thick as we age might be due to a loss of elasticity in the cells,” says Igor Sokolov of Clarkson University, who presented his latest research findings during a session on bio-imaging techniques at the Annual American Physical Society (APS) March meeting in Montreal.

GE Introduces new imaging solution for diagnosing certain diseases

Patients can now experience increased peace-of-mind and enhanced expert care during cardiac and vascular treatment, thanks to a first-of-its-kind imaging system from GE Healthcare.
