Sonohysterography is an alternative diagnostic tool for women with adenomyosis

Sonohysterography (SHG), a simple ultrasound technique commonly used to evaluate the uterine cavity, improves the diagnostic capability of transvaginal ultrasound in detecting adenomyosis (a common benign condition of the uterus that causes dysmenorrhea, abnormal vaginal bleeding and pelvic pain), according to a study performed at the Thomas Jefferson University Hospital in Philadelphia, PA.

Pretreatment MRI and PET/CT for cervical cancer improves chances for optimal treatment

Pretreatment MRI and PET/CT for cervical cancer may direct more women to optimal therapy choices and spare many women potential long-term morbidity and complications of trimodality therapy (surgery followed by chemoradiation), according to a study performed at the Institute for Technology Assessment in Boston, MA.

Study sheds light on underlying neural mechanism behind macular degeneration

In macular degeneration, the most common form of adult blindness, patients progressively lose vision in the center of their visual field, thereby depriving the corresponding part of the visual cortex of input.

Colonoscopy and virtual colonoscopy, either way get screened!

Today, patients have a wide selection of colorectal cancer screening exams from which to choose, unlike with other types of cancers.

Angiogenesis inhibitors, study points to limitations, solutions

A new generation of cancer drugs designed to starve tumors of their blood supply - called "angiogenesis inhibitors"-succeeds at first, but then promotes more invasive cancer growth-sometimes with a higher incidence of metastases, according to a new study in animals.

What role does the brain play in some women's lack of sexual desire?

More than 40 percent of women ages 18-59 experience sexual dysfunction, with lack of sexual interest - hypoactive sexual desire disorder, or HSDD - being the most commonly reported complaint, according to medical researchers.

Treatment for knee ligament damage

Injuries to the knee's medial cruciate ligament (MCL) may be treated successfully without surgery, according to a literature review published in the March 2009 issue of The Journal of the American Academy of Orthopaedic Surgeons (JAAOS). The key, the review's authors found, is properly diagnosing and understanding the extent of the injury to determine the best course of treatment.

fMRI captures wave of brain activity linked to anticipation

Neuroscientists at Georgetown University Medical Center have, for the first time, shown what brain activity looks like when someone anticipates an action or sensory input which soon follows.

Amyloid plaques may increase the activity of astrocytes

The impact of the amyloid plaques that appear in the brains of patients with Alzheimer's disease may extend beyond the deposits' effects on neurons – the cells that transmit electrochemical signals throughout the nervous system.

Scientists measure impact of high-fat diet on the spread of cancer

Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.

Ethnic differences found for fatty liver disease and insulin resistance

A new study suggests that the metabolic response to obesity and insulin resistance, particularly as it pertains to the liver, differs among ethnic groups in the U.S. African-Americans are more resistant to the buildup of fat in the abdominal adipose tissue and liver, and to high triglyceride levels associated with insulin resistance.

New insights into addiction

A new comprehensive review by researchers at the Montreal Neurological Institute (MNI), McGill University and the University of Cambridge, England provides vital insights into the neurological basis of addiction by investigating Parkinson's disease patients, who in some instances develop various addictions when undergoing medical treatment.

Targeted nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light. When heated with lasers, the actively targeted hollow gold nanospheres did eight times more damage to melanoma tumors in mice than did the same nanospheres that gathered less directly in the tumors.

Radiolabeled nanoparticles boost PET-CT combination imaging

In an attempt to decrease the amount of cancer-targeting nanoparticle needed to image tumors, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has developed a simple method for creating iron oxide nanoparticles labeled with 18F, a radioisotope that is easily detected using positron emission tomography (PET). The result is a nanoparticle that can be imaged using PET, computerized tomography (CT), and fluorescence imaging.
