Biological behavior of these tumors is not completely known, and their natural history is not predictable. This case report presents a patient with a sinonasal hemangiopericytoma. Diagnosis and management of these uncommon tumors is discussed.

alumina-supported cs3[re(c2o4)3] precursor has been synthesized  for preparation of re-cs/g-al2o3 catalyst. cs3[re(c2o4)3]  has been prepared from the reaction of recl3 with  h2c2o4.2h2o and cscl in water. the complex has been characterized by elemental analysis and various spectroscopy techniques such as ft-ir, uv-vis and 13c-nmr. the complex was supported on γ-al2o3 by column chromatography. ...

background: the rosemary extract (re) possesses various antioxidant, cytoprotective and cognition-improving bioactivities. in this study, we postulated which doses of re have a more effect on the hippocampus of middle-aged rats.   methods : in this experimental study, thirty-two middle-aged male wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of re (containing 40% carnosic ac...

Ginseng is now used worldwide as a traditional Oriental medicine. Ginsenosides, alsoknown as ginseng saponins, are responsible for most pharmacological efficacies of ginseng.This work aimed to assess the novel skin anti-photoaging potential of ginsenoside Re (Re), aprotopanaxatriol-type ginsenoside, by analyzing reactive oxygen species (ROS), pro-matrixmetalloproteinase-2 (proMMP-2) and -9 (pro...
