ORLANDO, FL (April 4, 2011) – Prostate cancer is the second leading cause of cancer-related death among American men. Yet population-wide screening programs have not reduced the number of deaths from the disease. By focusing screening programs on the men who are at greatest risk for aggressive disease or diagnosis at a young age, researchers think they could improve mortality rates and personalize the screening approach. For that reason, scientists have been looking for genetic markers to help them identify exactly which men are at high risk and require regular screening.

Reston, VA (March 29, 2011) — Medicare coverage and nationwide utilization of computed tomographic colonography (CTC), commonly referred to as virtual colonoscopy, has tripled in recent years, according to a study in the April issue of the Journal of the American College of Radiology (www.jacr.org). CTC employs virtual reality technology to produce a three-dimensional visualization that permits a thorough and minimally invasive evaluation of the entire colon and rectum.
ORLANDO, Fla. — Results of the NIH-AARP Diet and Health Study revealed that diabetes is associated with lower risk of prostate cancer in men but with higher risk of other cancers in both men and women. The data, to be presented at the AACR 102nd Annual Meeting 2011, held here April 2-6, also showed an association between diabetes and higher cancer mortality rates.
A new way of understanding the structure of proteins, polymers, minerals, and engineered materials will be published in the May 2011 issue of the journal Nature Materials. The discovery by two Penn State University researchers is a new type of symmetry in the structure of materials, which the researchers say greatly expands the possibilities for discovering or designing materials with desired properties.
LA JOLLA, CA – April 3, 2011 – In the constantly morphing field of protein structure, scientists at The Scripps Research Institute offer yet another surprise: a common "chaperone" protein in cells thought to help other proteins fold has been shown instead to loosen them.
The study was published in the April 3 issue of Nature Structural & Molecular Biology.
CHICAGO — In the largest study of its kind, researchers from a consortium of 44 universities and research institutions in the United States, including Rush University Medical Center, identified four new genes linked to Alzheimer's disease.
Each gene individually adds to the risk of having this common form of dementia later in life.
The findings, published in the April issue of Nature Genetics, offer new insight into the underlying causes of Alzheimer's disease.
PHILADELPHIA – In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.
Promising new research reveals a potentially highly effective treatment for heterotopic ossification (HO), a painful and often debilitating abnormal buildup of bone tissue. HO comes in two main forms—one that appears in children and is congenital, another that strikes wounded military personnel and surgery patients and is triggered by severe injuries and wounds.
An animal study by developmental biologists shows that a drug that interrupts a signaling-nuclear protein pathway can prevent HO. The study appeared online today in Nature Medicine.
Young adult patients with genetic heart diseases, such as hypertrophic cardiomyopathy (HCM), substantially benefitted from therapeutic hypothermia, which could further extend the role for this treatment strategy in new patient populations, according to a scientific presentation at the American College of Cardiology (ACC) Scientific Sessions in New Orleans, April 1-3.
In patients with HCM, despite rapid cardiopulmonary resuscitation (CPR) with defibrillation, survival following out-of-hospital cardiac arrest has been particularly unfavorable, explained the study authors.
Murray, UT (4/03/11) – Fasting has long been associated with religious rituals, diets, and political protests. Now new evidence from cardiac researchers at the Intermountain Medical Center Heart Institute demonstrates that routine periodic fasting is also good for your health, and your heart.
The sickle cell trait could be a cause—albeit rare—of sudden death in young African-American competitive athletes, most commonly during football training, according to a scientific poster that will be presented at the American College of Cardiology (ACC) Scientific Sessions, April 1-3, in New Orleans.
The Heart of New Ulm Project, which is merging environmental, peer leadership and individual interventions across an entire rural Minnesota community with the assistance of a healthcare system, worksites and the general community to prevent coronary heart disease, has shown a 24 percent reduction in the number of acute heart attacks in a five-quarter period, compared with the previous five-quarter period of evaluation.
This study will be presented at the 60th annual American College of Cardiology (ACC) Scientific Sessions in New Orleans on April 3.
ORLANDO, Fla. — Scientists have uncovered a genetic characteristic of metastatic prostate cancer that defines a rare sub-type of this disease. These findings are published in Cancer Discovery, the newest journal of the American Association for Cancer Research, which will debut at the AACR 102nd Annual Meeting 2011, held April 2-6.
ORLANDO, Fla. — Scientists at the Dana Farber Cancer Institute have identified a mutation in the DDR2 gene that may indicate which patients with squamous cell lung cancer will respond to dasatinib.
The findings are published in Cancer Discovery, the newest journal of the American Association for Cancer Research, debuting here at the AACR 102nd Annual Meeting 2011, from April 2-6.
ORLANDO, Fla. — A study published in Cancer Discovery, the newest journal of the American Association for Cancer Research, debuting here at the AACR 102nd Annual Meeting 2011, held April 2-6, showed how evaluating the immune response in the tumor microenvironment may help researchers better target therapy in breast cancer.
