Multidetector CT (MDCT) cystography (diagnostic procedure used to examine the bladder) can be used to detect vesicourethral leaks (a common problem) after prostatectomy according to a study that was performed at the Seoul National University College of Medicine in the Republic of Korea.

A stunning discovery based on epigenetics (the inheritance of propensities acquired in the womb) reveals that consuming choline—a nutrient found in eggs and other foods—during pregnancy may significantly affect breast cancer outcomes for a mother's offspring. This finding by a team of biologists at Boston University is the first to link choline consumption during pregnancy to breast cancer. It also is the first to identify possible choline-related genetic changes that affect breast cancer survival rates.
Coronary CTA offers a low cost, non-invasive alternative to conventional angiography for evaluating patients who are suspected of having coronary artery disease; true even if the patients have calcified coronary artery plaques, according to a study performed at the Thomas Jefferson University Hospital, Philadelphia, PA.
A dual-headed dedicated gamma camera used during molecular breast imaging (MBI) can accurately detect small breast tumors less than 2 cm in size, according to a study performed at the Mayo Clinic in Rochester, MN.
One-hundred fifty patients who had suspicious lesions smaller than 2 cm in size were imaged using dual-head molecular breast imaging. "There were 128 cancers confirmed in 88 patients," according to Carrie B. Hruska, MD, lead author of the study. "The sensitivity rate of dual-head MBI during the study was 90% (115/128)", she said.
In developing a model to explain the motion of atoms in a magnetic field, scientists have overcome a decades-old obstacle to understanding a key component of magnetic resonance.
The new understanding may eventually lead to better control of magnetic resonance imaging (MRI) and higher resolution MRI diagnoses.
Rockville, MD – Researchers used a new imaging technique to take high quality color photographs of the clinical stages of ocular inflammation in mice, and the technology could help in the monitoring and treatment of diseases of the eye that may cause blindness.
In the age of the petabyte, we all need help digesting and understanding massive amounts of information. In this month's Physics World, a series of features celebrates the ascendance of visual methods that are being used to make meaning of the mountains of scientific data.
Scientific visualizations can play a key role in fundamental physics, particularly when it comes to depicting the outcome of particle collisions at CERN's massive new Large Hadron Collider, but they can also shed light on much more everyday research.
Our immune system plays an essential role in protecting us from diseases, but how does it do this exactly? Dutch biologist Suzanne van Helden discovered that before dendritic cells move to the lymph nodes they lose their sticky feet. This helps them to move much faster. Immature dendritic cells patrol the tissues in search of antigens. After exposure to such antigens they undergo a rigorous maturation process. During this maturation the dendritic cells migrate to the lymph nodes to activate T cells.
MAPUTO, Mozambique (1 December 2008)—Concerned that the global financial crisis will lead to cuts in funding for projects in developing countries, leaders of the world's largest agricultural research group today told a conference that relatively modest, well-targeted investments could greatly boost the livelihoods of hundreds of millions of people living on less than $1 a day.
CHICAGO – The December issue of the Journal of the American Dietetic Association features research studies focusing on the everyday eating habits of consumers. Researchers look at why fast foods continue to be a popular meal choice and methods for adding healthier foods to a person's diet.
Studies published in the December 2008 Journal of the American Dietetic Association include:
The first comprehensive "inventory" of sea and land animals around a group of Antarctic islands reveals a region that is rich in biodiversity and has more species than the Galapagos. The study provides an important benchmark to monitor how they will respond to future environmental change.
Scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN) have uncovered new properties of imidazolium salts (IMSs), which suggest that they could play a vital role in disease prevention and treatment.
The report on the redox properties of IMSs was published in the Journal of the American Chemical Society.
In a separate study published in Angewandte Chemie International Edition, IBN researchers reported the first use of these salts to convert carbohydrates into versatile chemical compounds for biofuel production.
NYU Langone Medical Center released today the findings of a study on the New York University/Bellevue Primary Care Internal Medicine Residency Program (Bellevue/NYU PC Program), published in the November 2008 issue of Academic Medicine. This 23 year assessment of an extraordinary educational approach to residency training outcomes documents a unique educational approach, which has resulted in high personal and career satisfaction of residents and lower burnout rates – close to one third of that of their peers.
ROCHESTER, Minn. -- A new study from Mayo Clinic finds the use of the drug therapy etanercept ineffective in treating alcoholic hepatitis, an acute inflammation of the liver caused by excessive consumption of alcohol. The results of the study are published in the December issue of Gastroenterology (http://www.gastrojournal.org/).
