Background: Solitary fibrous tumor (SFT) is a mesenchymal tumor which is most commonly seen in the pleura; however it can be seen in other organs such as the meninge, gastrointestinal tract, soft tissue, bone, and skin. SFT should be differentiated from other mesenchymal tumors in these organs. Immunohistochemistry plays a pivotal role for the histopathologic diagnosis...

introduction: desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   case report: the patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. his ct-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. biopsy was compatible with desmoid fib...

Introduction: Solitary fibrous tumor is a rare, mesenchymal neoplasm that has been reported in numerous sites. Occurrence in the parotid gland is exceedingly rare.   Case Report: A 53-year-old man with a 2 cm solitary fibrous tumor of the left parotid gland, that was observed clinically and operatively and thought to be a neoplasm arising from Stensen's duct, is described. A pre-operative CT sc...

Three-dimensional (3D) fibrous hydrogels were fabricated by blending two photoactive polymers, poly(ethylene glycol) diacrylate (PEGDA) and poly(vinyl alcohol) (PVA), and the resulting solution was electrospun. PEGDA is a commonly used hydrogel material for tissue engineering applications since its interaction with cells can be tuned by crosslinking in a variety of bioactive molecules including...

REPPER (REPeats and their PERiodicities) is an integrated server that detects and analyzes regions with short gapless repeats in protein sequences or alignments. It finds periodicities by Fourier Transform (FTwin) and internal similarity analysis (REPwin). FTwin assigns numerical values to amino acids that reflect certain properties, for instance hydrophobicity, and gives information on corresp...

Collagens are the most abundant proteins in mammals, especially found in flesh and fibrous tissues. In total, 28 types of collagen are known of which type I is the most common. Structurally, a single type I collagen consists of three intertwined chiral -helixes coiled together, which self-assemble to form microfibrils and even larger fibril aggregates. Due to this supramolecular ordering, fibr...

We propose, as an alternative to conventional spectroscopic assays, a simple method for discriminating fibrous amyloid proteins by using a label-free semiconductor-based biosensor. The highly sensitive assay is expected to be useful for accelerating amyloid related research.
