Synthetic molecule helps detect heart attack in the making

A new bright spot in heart disease research may soon allow physicians to peer directly into patients' blood vessels and find dangerous cholesterol-filled plaques before they rupture and cause a heart attack.

Optical biopsy finds cancers in first tests on human tissue

In its first laboratory tests on human tissue, a light-based probe built by researchers at Duke University's Pratt School of Engineering almost instantly detected the earliest signs of cancer in cells that line internal organs.

African Americans may be at higher risk of heart failure because of racial variations in heart muscle's pumping ability

Scientists have known for nearly a decade that African Americans have higher rates of hospitalization for heart failure than other major U.S. racial or ethnic groups, but until now they have had limited information other than socio-economic and demographic characteristics to explain why this is so.

More women with family breast cancer history inquiring about MRI screening following ACS guidelines

More women with a family history of breast cancer are asking their physicians whether they should undergo breast magnetic resonance imaging scans after American Cancer Society guidelines released on Wednesday recommended the screening for women at high risk of developing the disease, the Baltimore Sun reports.

Precise region in the frontal cortex may be specialised for learning social information

Is there a specific memory for events involving people Researchers in the Vulnerability, Adaptation and Psychopathology Laboratory (CNRS/University Paris VI France ) and a Canadian team at Douglas Hospital, McGill University (Montreal), have identified the internal part of the prefrontal cortex as being the key structure for memorising social information.

Iron nanoparticles exhibit toxic effects on neuronal cells

Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions.

Radiofrequency (RF) ablation effective for treating inoperable lung cancer

A minimally invasive procedure known as radiofrequency (RF) ablation is effective for treating lung cancer in patients who are not candidates for surgery, according to a Rhode Island Hospital study published in the April issue of the journal Radiology.

RF ablation used to treat early-stage, inoperable cancer

Lung cancer patients who are not candidates for surgery now have another safe and effective treatment option: radiofrequency (RF) ablation, according to a new study published in the April issue of the journal Radiology.

Women with a recent diagnosis of cancer in one breast should have MRI screening of the opposite breast

The international research team found that MRI, or magnetic resonance imaging, detected cancer in the opposite breast in 30 of 969 women (3.1 percent) who had recently been diagnosed with cancer in one breast only. The cancers in the opposite breast were missed by previous mammography and clinical exam.

MRI as a key component of the diagnostic workup for women with breast cancer

Up to 10 percent of women newly diagnosed with cancer in one breast develop cancer in the opposite breast.

Annual computed tomography screening identifies a high proportion of patients with early-stage lung cancer

Lung cancer remains the leading cause of cancer death in both men and women, killing more people than breast, prostate and colon cancers combined, according to the American Cancer Society (ACS). According to the study, the estimated cure rate for lung cancer in the absence of screening is approximately 5 percent, but increases significantly when the cancer is diagnosed and treated at its earliest stage.

Arthritis pain processed in parts of brain concerned with emotions and fear

Researchers at The University of Manchester have discovered that arthritis pain, unlike that induced as part of an experiment, is processed in the parts of the brain concerned with emotions and fear.

Research agreement to advance new imaging technology

The University of Rochester Medical Center (URMC) and T.I.E.S., LLC, a Rochester-based start-up company, have entered into a research partnership to evaluate a new technology that could ultimately represent a major advance in medical imaging.

CT screening regimen finds early-stage lung cancer

Annual computed tomography (CT) screening identifies a high proportion of patients with early-stage lung cancer, according to the latest findings of the NewYork-Presbyterian Hospital/Weill Cornell Medical Center -- led New York Early Lung Cancer Action Project (NY-ELCAP) published in the April issue of the journal Radiology.

Autistic children can interpret the mental state of others by looking at their eyes

In findings that contradict previous studies, psychologists found that autistic children can 'read' a stranger's mental state based on that person's eyes. Autistic children have long been thought to be poor at interpreting people's mental states based on facial expressions, especially expressions around the eyes.

American Cancer Society issues recommendation on MRI for breast cancer screening

An expert panel convened by the American Cancer Society has developed new recommendations for the use of magnetic resonance imaging (MRI) for women at increased risk for breast cancer, and recommends annual screening using MRI in addition to mammography for women with a 20-25 percent or greater lifetime risk of the disease.

MRI evaluation of the contralateral breast in women recently diagnosed with breast cancer

Magnetic Resonance Imaging (MRI) scans of women who were diagnosed with cancer in one breast detected over 90 percent of cancers in the other breast that were missed by mammography and clinical breast exam at initial diagnosis, according to a new study.

28 Mar 2007

MRI improves breast cancer diagnosis

Women who have been diagnosed with breast cancer in one breast have a higher risk of contracting the disease in their opposite breast as well. A thorough examination of the opposite breast using mammography and ultrasound is therefore common practice. However, many tumours still remain undetected when using mammography.

Treating sleep apnea with continuous positive airway pressure reduces incidence of stroke

Patients with moderate to severe sleep apnea who have significantly higher serum levels of inflammatory markers that serve as precursors to coronary artery disease, as well as lesions associated with silent brain infarction, have an elevated risk of stroke, according to a group of Japanese medical researchers.

Clinical and imaging evidence of Zolpidem effect in hypoxic encephalopathy

A new study reported that zolpidem, a drug normally used to treat insomnia, temporarily improved brain function in a patient suffering from akinetic mutism, a condition in which the person is alert but cannot speak or move.
