Structures and characterization of m-nisoldipine polymorphs
CrystEngComm, 2012, Advance ArticleDOI: 10.1039/C2CE06359J, PaperCaiqin Yang, Zhenwei Zhang, Yanli Zeng, Jing Wang, Yongli Wang, Baoqing MaTwo polymorphs of m-nisoldipine were prepared and structurally characterized by X-ray diffraction. Polymorphs A and B show distinct colors, morphologies, IR, Raman, DSC, and terahertz spectroscopies. DFT calculations were conducted to correlate the terahertz absorption and the intermolecular interactions. An enantiotropic relationship between the two forms is observed with a conversion temperature of 47 [degree]C.To cite this article before page numbers are assigned, use the DOI form of citation above.The content of this RSS Feed (c) The Royal Society of Chemistry (Source: RSC - CrystEngComm latest articles)

Reconstruction After Partial Laryngectomy Improved With Donor Aortic Graft
Massachusetts General Hospital (MGH) surgeons have developed a new technique for reconstructing the larynx after surgery for advanced cancer. In the May Annals of Otology, Rhinology and Laryngology, they describe how this approach - which uses cryopreserved aortas from deceased donors to replace removed larynx tissue - allowed patients to avoid a permanent tracheotomy and maintain voice and swallowing function with no need for immunosuppressive medications...
