Abstract
Paneth cell metaplasia (PCM) typically arises in pre-existing gastrointestinal (GI) diseases; however, the mechanistic pathway that induces metaplasia and whether PCM is initiated exclusively by disorders intrinsic to the GI tract is not well known. Here, we describe the development of PCM in a murine model of chronic myelogenous leukemia (CML) that is driven by an inducible bcr-abl oncogene. Mechanistically, CML induces a proinflammatory state within the GI tract that results in the production of epithelial-derived IL-33. The binding of IL-33 to the decoy receptor ST2 leads to IL-9 production by type 2 innate lymphoid cells (ILC2) which is directly responsible for the induction of PCM in the colon and tissue remodeling in the small intestines, characterized by goblet and tuft cell hyperplasia along with expansion of mucosal mast cells. Thus, we demonstrate that an extra-intestinal disease can trigger an ILC2/IL-9 immune circuit, which induces PCM and regulates epithelial cell fate decisions in the GI tract.

Abstract
Neuroinflammation is a recognized complication of immunotherapeutic approaches such as immune checkpoint inhibitor treatment, chimeric antigen receptor therapy, and graft versus host disease (GVHD) occurring after allogeneic hematopoietic stem cell transplantation. While T cells and inflammatory cytokines play a role in this process, the precise interplay between the adaptive and innate arms of the immune system that propagates inflammation in the central nervous system remains incompletely understood. Using a murine model of GVHD, we demonstrate that type 2 cannabinoid receptor (CB2R) signaling plays a critical role in the pathophysiology of neuroinflammation. In these studies, we identify that CB2R expression on microglial cells induces an activated inflammatory phenotype which potentiates the accumulation of donor-derived proinflammatory T cells, regulates chemokine gene regulatory networks, and promotes neuronal cell death. Pharmacological targeting of this receptor with a brain penetrant CB2R inverse agonist/antagonist selectively reduces neuroinflammation without deleteriously affecting systemic GVHD severity. Thus, these findings delineate a therapeutically targetable neuroinflammatory pathway and has implications for the attenuation of neurotoxicity after GVHD and potentially other T cell-based immunotherapeutic approaches.

Abstract
Acute cholangitis is a biliary tract infection secondary to the obstruction, which causes biliary stasis and bacterial overgrowth. Typically, it presents with the Charcot triad of right upper quadrant abdominal pain, jaundice, and fever. Most acute cholangitis cases are secondary to choledocholithiasis. There are rare cases resulting from pancreatic neoplasm. We report the case of a 43-year-old Caucasian male who was found unresponsive at home with hypotension, anemia, and severe jaundice. Initial imaging studies were notable for a periampullary mass lesion causing intrahepatic biliary ductal dilation. Endoscopic retrograde cholangiopancreatography (ERCP) revealed an actively oozing periampullary fungating mass. In this case, acute cholangitis and hemorrhagic shock secondary to bleeding periampullary lesions are atypical. This case presents an effective treatment plan for this condition.

Abstract
Rho GTPases such as Rho, Rac, and Cdc42 are important regulators of the cortical cytoskeleton in processes including cell division, locomotion, and repair. In these processes, Rho GTPases assume characteristic patterns wherein the active GTPases occupy mutually exclusive "zones" in the cell cortex. During cell wound repair, for example, a Rho zone encircles the wound edge and is in turn encircled by a Cdc42 zone. Here we evaluated the contributions of cross-talk between Rho and Cdc42 to the patterning of their respective zones in wounded Xenopus oocytes using experimental manipulations in combination with mathematical modeling. The results show that the position of the Cdc42 zone relative to the Rho zone and relative to the wound edge is controlled by the level of Rho activity. In contrast, the outer boundary of the Rho zone is limited by the level of Cdc42 activity. Models based on positive feedback within zones and negative feedback from Rho to the GEF-GAP Abr to Cdc42 capture some, but not all, of the observed behaviors. We conclude that GTPase zone positioning is controlled at the level of Rho activity and we speculate that the Cdc42 zone or something associated with it limits the spread of Rho activity.

Abstract
Formation of wedge-shaped neuroepithelial cells, owing to the constriction of apical bands of microfilaments, is widely believed to play a major part in bending of the neural plate. Although cell "wedging" occurs during neurulation, its exact role in bending is unknown. Likewise, although microfilament bands occupy the apices of neuroepithelial cells, whether these structures are required for cell wedging is unknown. Finally, although it is known that cytochalasins interfere with neurulation, it is unknown whether they block shaping or furrowing of the neural plate, or elevation, convergence, or fusion of the neural folds. The purpose of this study was to reexamine the role of microfilaments in neurulation in the chick embryo. Embryos were treated with cytochalasin D (CD) to depolymerize microfilaments and were analyzed 4-24 hr later. CD did not prevent neural plate shaping, median neural plate furrowing, wedging of median neuroepithelial cells, or neural fold elevation. However, dorsolateral neural plate furrowing, wedging of dorsolateral neuroepithelial cells, and convergence of the neural folds were blocked frequently by CD. In addition, neural folds always failed to fuse across the midline in embryos treated with CD, and neural crest cell migration was prevented. These data indicate that only the later aspects of neurulation may require microfilaments, and that certain neuroepithelial cells, particularly those that normally wedge with median furrowing and elevation of the neural folds, become (and remain) wedge-shaped in the absence of apical microfilament bands. Thus, microfilament-mediated constriction of neuroepithelial cell apices is not the major force for median neuroepithelial cell wedging and elevation of the chick neural plate. Further studies are needed to localize the motor(s) for these processes.

Abstract
In a double blind study 30 male patients subjected to peroral endoscopy were given 0.5 mg glucagon (G) and 50 mg pethidine plus 0.5 mg atropine (PA) intravenously for premedication. The results showed that the PA group of patients had less discomfort, vomiting, salivary and gastric secretion during the examination than the G group. The arrestment of motility was significantly more prolonged in the G group of patients; otherwise no difference was found regarding the relaxation of the antrum, pylorus and duodenal bulb. This suggests glucagon to be superior to pethidine plus atropine when examinating these regions except in anxious patients which probably should have a sedative in addition to glucagon as premendication for peroral endoscopy.
