Lack of oxygen in body tissues creates a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung

What's more, the team demonstrated through studies in people and animals that inhalation of a 'souped up' form of nitric oxide, which targets red blood cells, reverses the blood abnormality to restore normal lung pressure.

Combining optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer

A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions--and potentially reduce the number of breast biopsies performed. The study appears in the October issue of the journal Radiology.
