Bone loss can occur in one bone or spread to soft tissue and adjacent bones. Although the disease may strike any of the bones of the body, it is more often recognized earlier when the calvarium and/or the mandible are involved. Because of its rarity, the disorder often goes unrecognized, and lack of agreement on how best to treat Gorham-Stout GANT61 datasheet syndrome can delay the provision of treatment. We report the case of a 58-year-old man whose left body and ramus of mandible had disappeared as a result of massive osteolysis. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 109: e41-e48)”
“The phase morphology
developing in immiscible poly(styrene-co-acrylonitrile) (SAN)/ethylene-propylene-diene monomer (EPDM) blends was studied with an in situ reactively generated SAN-g-EPDM compatibilizer through the introduction of BEZ235 research buy a suitably chosen polymer additive (maleic anhydride) and 2,5-dimethyl-2,5-di-(t-butyl peroxy) hexane (Luperox) and dicumyl peroxide as initiators during melt blending. Special attention was paid to the experimental conditions required for changing the droplet morphology for the dispersed phase. Two different mixing sequences (simple and two-step) were used. The product of two-step blending was a major phase surrounded by rubber particles; these rubber particles contained the occluded matrix phase.
Depending on the mixing sequence, this particular phase morphology could be forced or could occur spontaneously. The composition was stabilized by the formation of the SAN-g-EPDM copolymer between the elastomer and addition polymer, which was characterized with Fourier transform infrared. As for the two initiators, the blends with Luperox showed better mechanical Bindarit in vitro properties. Scanning electron microscopy studies
revealed good compatibility for the SAN/EPDM blends produced by two-step blending with this initiator. Dynamic mechanical thermal analysis studies showed that the two-step-prepared blend with Luperox had the best compatibility. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 1417-1425, 2011″
“Structural, magnetic, and electronic transport properties of Bi0.6-xLaxCa0.4MnO3 (0 <= x <= 0.6) manganites have been studied systematically. The parent compound exhibits robust charge ordered antiferrromagnetic (COAFM) phase with T-CO similar to 293 K and AFM Neel temperature T-N similar to 149 K. The sample with x = 0.1 show a M (T) curve of “”arch bridge”" form between 142 and 253 K, which is attributed to the AFM peak embedded in the broad transition of the CO. For the middle doping samples (0.2 <= x <= 0.4), although the CO peaks disappear as a result of the suppression of the long range CO state, AFM superexchange coupling has been strengthened with the increasing of La doping level. The Bi0.1La0.5Ca0.4MnO3 sample shows interesting phenomena such as magnetization steps and magnetic memory effect.
