“Metastatic paranasal sinuses and orbital cancer is very rare. The patient with sinusitis and orbital symptoms warrants a detailed history, complete physical examination and serial radiological tests (sinus radiographs and CT scan) to rule out any metastatic disease and prompt treatment. We present a case of 65 HIF activation years old patient with metastatic prostate cancer who presented
to us with left ethmoid sinuses and orbital metastasis causing ipsilateral proptosis.”
“Room temperature imidazolium-based ionic liquids such as 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF(6)) have been used as effective liquid media for the synthesis of pure Au and bimetallic PdAu nanoparticles by direct synthesis and phase-transfer methods. The mode-of-stability, long-term stability, and long lifetimes of these ionic-liquid supported nanoparticle catalysts, all of which are important factors in determining the overall “greenness” of such materials, were investigated. Four different stabilizing systems in BMIMPF(6) ILs were investigated: poly(vinylpyrrolidone) (PVP), 1-methylimidazole, 1-(2′-aminoethyl)-3-methylimidazolium hexafluorophosphate, and pure BMIMPF(6) IL with the absence of a secondary stabilizer.
The stability of pure Au nanoparticles synthesized by the above four stabilizers was studied using selleck chemicals UV-vis spectroscopy and transmission 17DMAG electron microscopy (TEM). It was found that PVP-stabilized nanoparticles were the most stable to aggregation. The catalytic activity of the resulting PdAu nanoparticles
was examined for the hydrogenation of 1,3-cyclooctadiene and 3-buten-1-ol across all of the systems to understand which stabilizer(s) are most optimal for nanoparticle catalyst synthesis and usage; particularly which systems have high catalytic activity and selectivity as well as long catalyst lifetimes. In agreement with Au nanoparticle stability results, PVP-stabilized PdAu nanoparticles were the most catalytically active due to improved nanoparticle stability, followed by nanoparticles stabilized by 1-methylimidazole, amine-functionalized IL and the pure BMIMPF(6) IL (C) 2010 Elsevier B.V.

“This study examined the potential biochemical and mechanical structures that may contribute to egg adhesion in European whitefish Coregonus lavaretus. Experiments showed that eggs from a population of C. lavaretus from Loch Eck remained non-adhesive in a solution chemically similar to ovarian fluid but became adhesive seconds after contact with water. Examination of the ultrastructure of the chorion showed that the morphology changed significantly after contact with water, with nodule-like protuberances attached to connective filaments on the surface present in water-hardened but not non-water hardened eggs.
