Studies and Analyses

Lycopene, an antioxidant commonly found in tomatoes and tomato-based products, is commonly perceived to reduce the risk of developing prostate cancer.

A new study at Northwestern University seeks to determine whether natural tomato oil with a high concentration of lycopene may reverse or delay progression of high-grade prostatic intraepithelial neoplasia (HGPIN), a condition in which abnormal cells form within the prostate and which is the strongest risk factor yet identified fo

Scientists for the first time have identified a fault in the brain waves of schizophrenics that may explain their hallucinations and disturbed thinking. The study, by a team at the Veterans Affairs (VA) Boston Healthcare System and Harvard Medical School, appears in the Nov. 8 Proceedings of the National Academy of Sciences.

The researchers studied the brain waves of normal and schizophrenic patients as they responded to images. Those with the disorder showed no electrical activ

University of Minnesota cancer researcher says shedding excess pounds may be key in preventing often fatal disease

A study from the University of Minnesota Cancer Center indicates that overweight and obesity could more than double an older woman’s risk of acute myelogenous leukemia (AML), an often fatal cancer of the bone marrow and blood. The results of the study are published in the November issue of Cancer Epidemiology, Biomarkers and Prevention journal.

First-Ever Genetic Study of Late-Onset Alzheimer’s Disease in Hispanic Families

Researchers at Columbia University Medical Center have found two locations in the human genome that may harbor genes that increase the risk of Alzheimer’s disease. If confirmed, they will be the first genes linked to Alzheimer’s disease since ApoE4 was discovered in 1993. The findings are published in the November issue of Molecular Psychiatry, a journal of the Nature Publishing Group. “We feel confid

Air pollution may trigger and accelerate narrowing of carotid arteries, according to a study presented at the American Heart Association’s Scientific Sessions 2004.

Researchers found an association between long-term air pollution exposure and the early stages of atherosclerosis (hardening of the arteries). “We knew that people in more polluted areas die earlier from cardiovascular disease, but it was not clear how early in the disease process air pollution contributes. Our stu

A new study finds surgery to transplant an ovary to the upper arm is feasible and preserves hormonal function in women undergoing treatment for cervical cancer. The report details the technical procedure and outcome of only the second successful human ovarian autotransplantation in the world. The study will be published in the December 15, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this study will be available via the CANCER News Room upon o
