This provides a new insight for preparing novel perovskite nanoparticles for special applications.Surface-enhanced Raman spectroscopy (SERS) has been recognized as a promising analytical technique owing to its merit of nondestructive and fast detection capabilities. However, SERS usually suffers signal interferences from different analytes or a complicated matrix. Separation is an effective approach to solve the signal interference in the application of SERS. It was proposed that two concentric coffee rings could serve as a simple separation platform; however, there are still many questions to be answered for in-depth understanding. In this study, critical parameters during the formation of two concentric coffee rings are characterized for a better understanding of this phenomenon, including surface tension, surface morphology, and surface energy. Two arsenicals, including arsenate (AsV) and cacodylic acid (DMAV), are chosen to study the arsenicals' separation/migration mechanism due to their significant difference in chemical properties. In the typical coffee ring, these two arsenicals have signal interference and only DMAV is detected via SERS; however, they are detected along the radius of the two concentric coffee rings. The distribution of arsenicals on the two concentric coffee rings is further verified by the chromatographic method. Under this simple platform, interactions between the arsenicals and the surface of the silver nanofilm are pivotal to their migration/separation. By surface modification of silver nanofilm with small molecules, the surface polarity and surface ζ potential are manipulated. The signal dynamics of these two arsenicals are studied on these modified silver nanofilms. RO4929097 It is clear that the electrostatic interaction plays a more important role than the polarity in the arsenicals' migration. This study reveals the mechanism of small molecule migration/separation in the two concentric coffee rings and provides insights for future study of employing this simple platform.INTRODUCTION  There is no data regarding the incidence and treatment of deep infection affecting the surgical implants after rib fixation. The aim of this study is to share our experience in the management of infected material after surgical rib fixation. METHODS  The medical records of operated patients from January 2012 to December 2018 were retrospectively analyzed. RESULTS  Three patients out of 87 (3.44%) developed an infection. One patient was treated conservatively and two patients were operated for hardware removal. CONCLUSIONS  The lack of evidence prompts for the design of surgical databases to share experience and enhance available data.

METHODS  A retrospective study on 22 patients (15 thymomas, 7 thymic cancers) who underwent tumor resection with concomitant SVC reconstruction. All the patients underwent vascular conduit reconstruction by the cross-clamping technique. The corresponding data were reviewed, including clinical presentation, operation management (surgery procedure, selection of suitable graft, strategies against SVC syndrome, etc.), postoperative cares (antithrombotic agent application, treatments on brain edema, etc.), and follow-up information. RESULT  Two patients were myasthenic, well controlled by oral pyridostigmine. All resections were radical (R0). Ten patients received induction treatment. All the 15 thymoma patients were Masaoka stage III (type B1-B3). As for thymic cancer, six patients were Masaoka stage III and one was stage ieme Verlag KG Stuttgart · New York.in English, German ZIEL  Überprüfung des Wertes der Diffusionsbildgebung (DWI) bei der korrekten Identifizierung von zöliakalen (CG) und zervikothorakalen (CTG) sympathischen Ganglien in der multimodalen Ganzkörper-PSMA-Liganden-PET/MRT, angesichts ihres häufig irreführenden Uptakes im PET, was möglicherweise für bösartige Läsionen wie Lymphknotenmetastasen sprechen kann. METHODEN  Die Dicke und der Grad der Diffusionsrestriktion wurde qualitativ und quantitativ in 406 sympathischen Ganglien (189 CTG bei 101 Männern und 217 CG bei 116 Männern) auf DWI-Maps (b-Wert 0 und 800s/mm2) und ADC (“apparent diffusion coefficient”)-Maps (mittlerer ADC) des Ganzkörper-PET/MR 68Ga-PSMA-11 PET/MR bewertet. Um eine Referenzgruppe mit übereinstimmender Gangliengröße zu bilden, wurde von jedem Patienten mit Metastasen der kleinste Lymphknoten ausgewählt und dem gleichen Verfahren unterzogen. ERGEBNISSE  Bei der Mehrheit der sympathischen Ganglien (81,0 % der CTG, 67,3 % der CG und 73,6 % von allen) wurde eine sehr geringe bzw. niedrige Diffusionsrestriktion festgestellt. Bei den meisten Lymphknotenmetastasen (91,7 %) war der Grad der Diffusionsrestriktion moderat bis hoch. Die mittleren ADC-Werte in den sympathischen Ganglien waren in CTG, in CG und in allen Ganglien statistisch signifikant höher als in den Lymphknotenmetastasen (p  less then  0.001; bei großer Effektstärke). SCHLUSSFOLGERUNGEN  Sympathische zöliakale und zervikothorakale Ganglien zeigen in der visuellen DWI-Bewertung eine sehr niedrige bzw. niedrige Diffusionsrestriktion und in den meisten Fällen signifikant höhere mittlere ADC-Werte als Lymphknotenmetastasen und kann somit als zusätzliche Faktor bei der Differentialdiagnose in der multimodalen PSMA-Liganden-PET/MR-Bildgebung dienen. Daher scheint für eine korrekte Identifizierung von sympathischen Ganglien die PSMA-Liganden PET/MRT der PSMA-Liganden PET/CT potentiell überlegen zu sein.Lupinifolin, a plant flavonoid, has been reported to possess various pharmacological effects. It most likely exerts low oral bioavailability because of poor water solubility. The objective of this study was to develop lipid nanocarriers as drug delivery systems to increase the gastrointestinal absorption of lupinifolin extracted from Albizia myriophylla. Three types of nanocarriers, lupinifolin-loaded solid lipid nanoparticles, lupinifolin-loaded nanostructured lipid carriers, and lupinifolin-loaded nanoemulsions, were prepared by an emulsification-sonication technique. All three types of nanocarriers loaded with lupinifolin, lupinifolin-loaded solid lipid nanoparticles, lupinifolin-loaded nanostructured lipid carriers, and lupinifolin-loaded nanoemulsions, were successfully synthesized. The lipid components chosen to formulate nanocarriers were tripalmitin and/or medium chain triglyceride. Physicochemical characterizations along with releasing profiles of lupinifolin-loaded lipid nanocarriers were compared. It was found that the best lipid nanocarrier for lupinifolin was lupinifolin-loaded nanostructured lipid carriers, which demonstrated the particle size of 151.
