Background and Objective: Different mechanisms may lead to the development of soft tissue tumor-like lesions in the oral cavity. Many of these lesions can be identified as specific entities on the basis of their histopathological features and are divided into fibrous, vascular, and giant cell types. The purpose of this study was to establish the relative prevalence of the different histopath...

BACKGROUND AND PURPOSE Previous studies demonstrated that carotid plaques analyzed by CTA can show contrast plaque enhancement. The purpose of this preliminary work was to evaluate the possible association between the fissured fibrous cap and contrast plaque enhancement. MATERIALS AND METHODS Forty-seven consecutive (men = 25; average age = 66.8 ± 9 years) symptomatic patients studied by use ...

Stimuli-responsive materials are promising as smart materials for a range of applications. In this work, a photo-crosslinkable, thermoresponsive macromer was electrospun into fibrous scaffolds containing gold nanorods (AuNRs). The resulting fibrous nanocomposites composed of poly(N-isopropylacrylamide-co-polyethylene glycol acrylate) (PNPA) and PEGylated AuNRs were crosslinked and swollen in wa...

Cell surface changes that accompany the complex life cycle of Streptomyces coelicolor were monitored by atomic force microscopy (AFM) of living cells. Images were obtained using tapping mode to reveal that young, branching vegetative hyphae have a relatively smooth surface and are attached to an inert silica surface by means of a secreted extracellular matrix. Older hyphae, representing a trans...

One percent of infants are born with congenital heart disease (CHD), which commonly involves outflow tract (OFT) defects. These infants often require complex surgeries, which are associated with long term adverse remodeling effects, and receive replacement valves with limited strength, biocompatibility, and growth capability. To address these problematic issues, researchers have carried out inv...

Solitary fibrous tumor is a rare mesenchymal neoplasm, characterized by peculiar histological features composed by the proliferation of spindle cells in "patternless pattern". Although it has been known to sometimes be accompanied by epithelioid cells, the presence of a well-formed epithelial structure is far more rare. We describe herein the case of a 60-year-old female with the radiological f...

Fibrous cap smooth muscle cells (SMCs) protect atherosclerotic lesions from rupturing and causing thrombosis, while other plaque SMCs may have detrimental roles in plaque development. To gain insight into recruitment of different plaque SMCs, we mapped their clonal architecture in aggregation chimeras of eGFP+Apoe-/- and Apoe-/- mouse embryos and in mice with a mosaic expression of fluorescent ...

The localization of ubiquitin (UB) signals in the acrosomes of rat spermiogenic cells was investigated by immunoelectron microscopy using two anti-UB antibodies: UB1, reacting with ubiquitinated proteins and free UB; and FK1, recognizing polyubiquitinated proteins but not monoubiquitinated proteins or free UB. Labeling of UB by UB1 (UB1 signal) was detected in the acrosomes at any stage of diff...
