BACKGROUND A solitary fibrous tumour (SFT) is an unusual neoplasm typically found in soft tissues. Although SFTs can arise in the bones, they very rarely arise in the vertebral arch. Here, we describe a case of a SFT that arose in the vertebral arch of the first lumbar (L1) spinal vertebrae and mimicked osteosarcoma. CASE PRESENTATION A 49-year-old woman presented with a 2-month history of lo...

Fructans are fructose polymers synthesized from sucrose in the plant vacuole. They represent short- and long-term carbohydrate reserves and have been associated with abiotic stress tolerance in graminean species. We report the isolation and characterization of a putative sucrose:fructan 6-fructosyltransferase (6-SFT) gene from a Patagonian grass species, Bromus pictus, tolerant to drought and c...

A renal solitary fibrous tumor (SFT) is an unusual and especially rare entity. Preoperative diagnosis usually difficult, but it remains of favorable prognosis. In this study, the authors report a case 33-year-old Moroccan man with history left pyelolithotomy who presented 19 cm mass associated two kidney stones in lower calyx. He underwent open radical nephrectomy, pathology revealed SFT. To be...

SFT, a stimulator of iron (Fe) transport, has been described as a transmembrane protein that facilitates the uptake of ferrous and ferric iron in mammalian cells. This study was initiated to investigate the 5' regulatory region of SFT and its role in the etiology of hereditary hemochromatosis. Sequence analyses of the putative 5' regulatory region revealed that the SFT cDNA sequence corresponds...

Independent security functional testing on a product occupies a backseat in traditional security evaluation because of the cost and stringent coverage requirements. In this paper we present the details of an approach we have developed to automate security functional testing. The underlying framework is called TAF (Test Automation Framework) and the toolkit we have developed based on TAF is the ...

Solitary fibrous tumor (SFT) of the kidney is a rare entity and usually displays a favorable prognosis. We herein report a second case of renal SFT developing local recurrence. A 50-year-old man was referred to our hospital because of a left renal mass. An abdominal CT detected a large renal tumor and radical nephrectomy was performed with a possible diagnosis of renal cell carcinoma. The resec...

Solitary fibrous tumour (SFT) is a mesenchymal neoplasm of subendothelial origin that can be found in all anatomical locations, but rarely in the lungs. A 71-year old female was referred to our hospital because of the increase in size of a solitary pulmonary mass. Chest contrast-enhanced dynamic computed tomography showed a well-circumscribed lobulated mass measuring 3.1×1.6 cm in the posterior...

Flowering of higher plants is orchestrated by complex regulatory networks through integration of various environmental signals such as photoperiod, temperature, light quality and developmental cues. In Arabidopsis, transcription of the flowering integrator gene FLOWERING LOCUS T (FT) that several flowering pathways converge to is directly regulated by more than ten transcription factors. Howeve...

Suppose S and T are shift equivalent mixing shifts of finite type, and / is a conjugacy from a subsystem of S to a subsystem of T. Then for any sufficiently large n, f extends to a conjugacy of Sn and Tn. A consequence of the proof is a fortified version of Wagoner's Stable FOG Theorem. Recall [Wi] that a nonnegative integral matrix A is the adjacency matrix of a directed graph whose arc set is...

In 1942 Stout and Murray first described hemangiopericytoma (HPC) as a vascular tumor composed of Zimmerman’s pericytes. In 1980 Wagner made the first histologic description of a solitary fibrous tumor (SFT) in the pleura, and in 1931 Klemperer and Rabin recognized it as a distinctive entity. Ultra-structurally, both the HPC and the SFT show variable characteristics of pericytic, fibroblast, an...
