Every year tens of millions reconstruction surgeries were performed to repair tissue defects caused by trauma or malignant tumor. As the composite tissues are very difficult to be preserved for a long time in vitro, "organ bank" was proposed. In addition to immune rejection, tissue cryopreservation is the key step of the "Organ Bank". In this study, two severed fingers were cryopreserved because the patients' conditions were not allowed to undergo the replantation immediately. The fingers were perfused with the cryopreservation solution through the digital artery at a speed of 1 ml/min, they were frozen following a control rate freezing procedure and stored in the liquid nitrogen. One finger was cryopreserved for 10 days and the other for 30 days. Both fingers were successfully replanted when the patient get better. After 1 year follow-up, the replanted fingers achieved satisfactory appearance and function. Our result demonstrate small composite tissues such as severed fingers can be cryopreserved and replanted successfully, which will help the patients who cannot receive the replantation immediately. This method will have important application value in cryobiology and clinical medicine. Beauveria pseudobassiana has great potential for use in the management of various insect pests. In the present study, we aimed to explore the the virulence of B. pseudobassiana isolated from a diversity of hosts to Bombyx mori and Tenebrio molitor larvae. To this end, 15 B. pseudobassiana isolates from 10 different geographical locations were identified based on morphological characteristics and molecular data. The phylogenetic positions of the isolates were evaluated according to morphological features and phylogenetic inferences based on six loci (nrSSU, nrLSU, TEF, RPB1, RPB2 and Bloc). In addition to growth in soil, the B. pseudobassiana isolates in our study were isolated from a wide host range that extended to 5 orders, 11 families, and 14 species. Moreover, anamorphically typified B. pseudobassiana was grown for the first time from teleomorph stromata. Pathogenicity of the B. pseudobassiana isolates from the different hosts was determined with two bioassays using B. mori and T. molitor larvae. The results indicated that mortality of B. mori caused by the lepidopteran isolates was significantly higher than that of isolates from other hosts, and virulence of the coleopteran isolates to T. molitor was significantly higher than that of isolates from other hosts. The host specificity of B. pseudobassiana should be studied in more detail before future consideration of isolates for use in biological control of pests. BACKGROUND No indication are available for transcatheter aortic valve implantation (TAVI) sizing in bicuspid aortic valve (BAV). Aim of the study is to develop and validate a Multi-Slice Computed Tomography (MSCT)-based algorithm for transcatheter heart valve (THV) sizing in patients with stenotic BAV under evaluation for TAVI. METHODS A two steps method was applied 1)evaluation of a cohort of 19 consecutive patients with type I BAV stenosis undergoing TAVI through pre and post-procedural MSCT, and development of an algorithm for THV sizing; 2)validation of the algorithm on a new cohort of 21 patients. RESULTS In the first cohort, a high correlation was found between the raphe-level area measured at pre-procedural MSCT and the smallest THV area measured at post-procedural MSCT (p  less then  0.001). Moreover, reduced THV expansion was observed among patients with higher calcium burden (p = 0.048). Then, a new algorithm for TAVI sizing in BAV was develop (CASPER Calcium Algorithm Sizing for bicusPid Evaluation with Raphe). This algorithm is based on the reassessment of the perimeter/area derived annulus diameter, according to three main anatomical features 1) the ratio between raphe length and annulus diameter; 2)calcium burden; 3)calcium distribution in relation to the raphe. The algorithm was then validated in a new cohort of 21 patients, achieving 100% of procedural success and excellent TAVI performance. CONCLUSION MSCT assessment of raphe length, calcium burden and its distribution is of crucial relevance in the pre-procedural evaluation of patients with BAV. These anatomical features can be combined in a new and simple algorithm for TAVI sizing. Crenolanib Idiopathic pulmonary fibrosis (IPF) is a chronic disease characterized by an abnormal healing response to injury of the alveolar epithelium. Tight junctions provide a physical barrier at the apical intercellular space between epithelial cells and regulate paracellular flux. While tight junction alterations are known to contribute to barrier dysfunction in a number of disease states, the role of tight junction proteins in IPF is poorly defined. To determine a potential role for tight junction protein alterations in IPF, we performed immunohistochemical staining for tight junction proteins ZO-1, occludin, claudin-2, claudin-3, claudin-4, claudin-5, and claudin-18. Staining intensity and localization were compared between IPF and control lung tissues. IPF was associated with type II pneumocyte hyperplasia and altered tight junction protein expression. While there was no difference in the expression of ZO-1, claudin-3, or claudin-5, between IPF and normal control, there was an overall increase in claudin-2 expression in bronchiolar and alveolar epithelium and a decrease in claudin-4 expression in type II pneumocytes. There was also increased occludin and decreased claudin-18 expression in pneumocytes overlying fibroblastic foci. These findings suggest that epithelial barrier alterations may be important to the pathogenesis of IPF. Animals in the wild must balance food intake with vigilance for predators in order to survive. The optic tectum plays an important role in the integration of external (predators) and internal (energy status) cues related to predator defense and prey capture. However, the role of neuromodulators involved in tectal sensorimotor processing is poorly studied. Recently we showed that tectal CRFR1 receptor activation decreases food intake in the South African clawed frog, Xenopus laevis, suggesting that CRF may modulate food intake/predator avoidance tradeoffs. Here we use a behavioral assay modeling food intake and predator avoidance to test the role of CRFR1 receptors and energy status in this tradeoff. We tested the predictions that 1) administering the CRFR1 antagonist NBI-27914 via the optic tecta will increase food intake and feeding-related behaviors in the presence of a predator, and 2) that prior food deprivation, which lowers tectal CRF content, will increase food intake and feeding-related behaviors in the presence of a predator.
