We report the crystal structures of two new coordination polymers that have similar composition but, despite having the same circuit symbol and Schläfli notation, different topologies: a novel 3D topology (USF-1) and a CdSO4-like topology.

Pancreatic cancer is the 4th leading cause of cancer death annually. Recent technological advances in imaging have led to non-uniformity in the evaluation of pancreatic neoplasms. The following article describes the history behind various biopsy techniques and the rationale for obtaining a biopsy of a pancreatic neoplasm and discusses the benefits and disadvantages of the various pancreatic biopsy techniques, including fine needle aspiration biopsy, Tru-cut needle biopsy, endoscopic brushings/cytology, and endoscopic ultrasound guided biopsies. A treatment algorithm for pancreatic neoplasms is then presented.

The role of mechanical circulatory support for cardiopulmonary failure is expanding. Anticoagulation in the setting of static blood, hypercoagulable states, extracorporeal circuits, and surgery presents an intricate and delicate balance. We present a patient with large, biventricular thrombi during and succeeding biventricular mechanical support. Management of the thrombi and device selection in this patient are discussed.
