... and below (structural overlap). "CBCT eliminates structural
overlap for a clearer view of early tumors," Ning said. "At the same time, the prototype machine captures images by rotating around the breast, not by flattening, or compressing, it in the painful way required in conventional mammography." CBCT cons...
Neuroimaging confirms the greater vulnerability of women's brains to alcohol
...hronic alcohol consumption may have on the brain's structural
and functional systems in women. "Epidemiological studies have demonstrated gender differences in alcohol-consumption behavior and the course of alcohol dependence," said Mann. "Women typically start to drink later in life, consume less per occasion...
New class of drugs may treat lung tumors resistant to Iressa and Tarceva
...these "irreversible inhibitors" overcomes both the structural
change resulting from the secondary EGFR mutation and the changes in receptor processing. Not only are Iressa-resistant NSCLC cells still sensitive to these irreversible inhibitors, but very few NSCLC cells treated with these new drugs ever become r...
High blood pressure causes pathological scars in the heart
... the heart in high blood pressure cases may suffer structural
changes thus producing massive scarring (myocardial fibrosis). Method for diagnosis and treatments 20 years ago it was thought that a progressive substitution of the heart muscle cells by inert fibres played a critical role in the deterioration of...
Penn study points to how COX-2 inhibitors can eventually lead to heart disease
...blood vessel was not changed, through a process of structural
reorganization of the blood vessel called vascular remodeling. In the second model, they reduced blood flow in arteries in the neck and looked at the downstream effects in the blood vessel. This time, instead of suppressing prostacyclin receptor sign...

map of the rat spinal cord, (b) make relevant comparisons with the human spinal cord and demonstrat...
Study explains why up to eight percent of cancers go undetected
...nges related to metabolism that often occur before structural
damage is evident. PET is the leading diagnostic tool for oncology patients because of its high sensitivity to detect malignancies. It also can identify recurrent disease before it spreads through the body. CT imaging is used to identify anatomic, or...

Non-invasive MRI technique distinguishes between Alzheimer's and frontotemporal dementia
... They also found that the perfusion data, added to structural
information about the brain obtained with conventional MRI, significantly improved the classification of FTD from normal aging. Thus, "we gained specificity and sensitivity," said Schuff. Schuff emphasized that because this was a research study, the ...
Genomics researchers discover protein deficit that causes drug toxicity
...yo Clinic researchers have discovered an inherited structural
mechanism that can make drugs for some diseases toxic for some patients. The mechanism decreases a protein and in turn causes certain individuals to metabolize thiopurine drugs differently. Thiopurine therapies are used to treat patients with childho...
Size of brain structure could signal vulnerability to anxiety disorders
...er that part of the experiment, the volunteers had structural
magnetic resonance (MR) images taken of their entire brains. The MR studies showed that those participants who appeared to have less anxiety response upon viewing the blue lights the second day, as measured by skin conductance, also had a thicker vm...
