Breast cancer is the second most common cancer amongst women, in Iran comprising 21.4% of female cancers. There are several screening modalities for breast cancer including breast self-examination, clinical breast examination and mammography.

Cerebral microinfarcts associated with severe cerebral beta-amyloid angiopathy.

Cerebral amyloid angiopathy (CAA) is common in elderly individuals, especially those affected with Alzheimer's disease. Eighteen brains with severe SCAA (SCAA) were compared with 21 brains with mild CAA (MCAA) to investigate whether the presence of SCAA in the brains of demented patients was associated with a higher burden of old microinfarcts than those with MCAA. Immunohistochemistry for CD68 was employed to highlight old microinfarcts in tissue blocks from various brain regions.

In vitro evaluation of forces exerted by a new computer-assisted colonoscope (the NeoGuide Endoscopy System).

Background: The NeoGuide Endoscopy System (NES) utilizes a fully articulated, computer-controlled insertion tube that allows proximal segments of the colonoscope to follow the path taken by the tip as it is manually advanced through the colon. The system was designed to eliminate looping and scope displacement during colonoscopy.

Material And Methods: Using in vitro testing, an inanimate flexible model of the colon incorporating four force transducers located at the key flexure points was employed to measure the axial forces on the colon wall during colonoscopy.
