Cellular power plant fault explains abnormal metabolism of tumours

The increased consumption of glucose that tumour cells exhibit, was thought to be a cause of the extra demand of building blocks required to keep up with an uncontrolled cell growth, but now it is more accepted that it could be the effect of a programmed metabolic change that favours this malignant growth.

Endobronchial valve improves quality of life in emphysema patients

Emphysema patients whose lungs are implanted with a pencil eraser-sized, one-way endobronchial valve experience significantly improved measures of lung function and report better quality of life, University of Pittsburgh School of Medicine researcher Frank C. Sciurba, M.D., reported today at CHEST 2007, the annual meeting of the American College of Chest Physicians.

Optical coherence tomography helps track multiple sclerosis

A five-minute eye exam might prove to be an inexpensive and effective way to gauge and track the debilitating neurological disease multiple sclerosis, potentially complementing costly magnetic resonance imaging to detect brain shrinkage - a characteristic of the disease's progression.

Eating raw fish raises potential health concerns

Two case studies from Japan presented at the 72nd Annual Meeting of the American College of Gastroenterology point to a potential health problem in the United States, as more Americans consume raw fish in the form of sushi and sashimi. Anisakiasis (round worm) is a human parasitic infection caused by the consumption of raw or undercooked seafood containing Anisakis larvae.

PET scans accurately detect a breast tumor's response to chemotherapy

Researchers in Australia have shown that positron emission tomography (PET) that uses a radioactive sugar molecule is more useful than mammography and ultrasound in predicting a breast tumour's response to chemotherapy and, therefore, the patient's ultimate likelihood of survival.

Test for lung cancer looks for discomforting quiet among protective genes

When it is quiet – "almost too quiet" – in movies, it is a sign that something is about to go wrong for the good guys.

Positron emission tomography reliably identifies dangerous cervical tumors

It doesn't matter how small or large it is, if a cervical tumor glows brightly in a PET scan, it's apt to be more dangerous than dimmer tumors.

Nuclear medicine approach can be first choice for excluding pulmonary embolism in young women

Young women at risk of having a pulmonary embolism - a potential life-threatening blockage in a lung artery - should first undergo a ventilation/perfusion lung scan (V/Q scan) rather than a CT (computed tomography) angiogram, conclude authors in a paper published in the September Journal of Nuclear Medicine.
