Pulmonary arteriovenous malformation causing lung sequestration and media infarction: a case report by Raffaella Griffo, Laura V. Klotz, Laura V. Klotz, Lena Brendel, Romina Rösch, Benedikt Niedermaier, Kai Schlamp, Mark Kriegsmann, Mark Kriegsmann, Martin M. Eichhorn, Martin M. Eichhorn, Hauke Winter, Hauke Winter

“…Direct communication of pulmonary arteries to pulmonary veins is the defining characteristic allowing venous blood to bypass the pulmonary capillary system and avoiding an efficient oxygenation process. The complexity of the pathology lies not only in the variety of its manifestations, but also in the choice of the most appropriate and effective treatment. …”

Synthesis, Adsorption, and Recognition Properties of a Solid Symmetric Tetramethylcucurbit[6]uril-Based Porous Supramolecular Framework by Fei-Yang Tian, Rui-Xue Cheng, Yun-Qian Zhang, Zhu Tao, Qian-Jiang Zhu

“…In this work, we reported a porous supramolecular framework (A) constructed of a symmetric tetramethylcucurbit[6]uril (TMeQ[6]) in aqueous HCl solutions; the driving force was the outer surface interaction of cucurbit[n]urils, as well as hydrogen bonding between latticed water molecules and portal carbonyl oxygens of TMeQ[6]. Adsorption experimental results revealed that the porous supramolecular framework can absorb certain fluorophore guests (FGs) to form luminescent assemblies (FG@As) by fluorescence enhancement or colour change, and some of them can respond to certain volatile organic compounds. …”

Different Angiogenic Potential in Low and High Grade Sporadic Clear Cell Renal Cell Carcinoma Is Not Related to Alterations in the von Hippel–Lindau Gene by Marcella M. Baldewijns, Iris J. H. van Vlodrop, Kim M. Smits, Peter B. Vermeulen, Gert G. Van den Eynden, Fiona Schot, Tania Roskams, Hein van Poppel, Manon van Engeland, Adriaan P. de Bruïne

“…Background: von Hippel–Lindau (VHL) inactivation is common in sporadic clear cell renal cell carcinomas (ccRCC). pVHL is part of the ubiquitin ligase complex that targets the alpha subunits of hypoxia-inducible transcription factor (HIF) for degradation under well-oxygenated conditions. In the absence of wild-type pVHL, as observed in VHL patients and most sporadic ccRCCs, constitutive upregulation of HIF results in transcriptional activation of angiogenesis-related genes, such as VEGF. …”
