AIMS Biliary intraductal tubular neoplasms that are non-mucinous and negative for MUC5AC are called intraductal tubulopapillary neoplasm (ITPNs). Intraductal tubular neoplasms with mucinous cytoplasm and MUC5AC positivity also occur, and their nature remains unclear although some pathologists may classify these as "IPNBs of gastric type". This study aimed to elucidate genetic features of biliary intraductal tubular neoplasms. METHODS Six resected cases of biliary intraductal neoplasm with >70% tubular configuration were characterized by the clinicopathological examination and whole exome sequencing, and obtained findings were compared between MUC5AC-positive (n=2) and -negative cases (n=4). RESULTS The intraductal tumours consisted of the pancreatobiliary-type epithelium with high-grade dysplasia arranged in back-to-back tubules. Both two MUC5AC-negative cases were non-invasive neoplasms developed in the liver, whereas all MUC5AC-positive cases had invasive carcinoma and were present in the intrahepatic (n=2), perihilar (n=1), and distal bile ducts (n=1). In an exome-sequencing study, MUC5AC-negative cases harboured mutations in CTNNB1, SF3B1, BAP1, and BRCA1 (one case each). KRAS mutations were observed in 3/4 MUC5AC-positive cases (75%) but none of MUC5AC-negative neoplasms. Compared to published data, known driver genes of other intraductal neoplasms of the pancreatobiliary systems (e.g., APC, CTNNB1, STK11, GNAS, and PIK3CA) were wild-type in all but one MUC5AC-negative case with CTNNB1 mutation. Chromatin modifiers (ARID1A, BAP1, and KMT2C) were also altered in MUC5AC-positive cases, similar to usual cholangiocarcinomas. CONCLUSIONS This exome-sequencing study suggested that MUC5AC-negative biliary ITPNs are genetically distinct from pancreatic ITPNs and IPNBs. They may also biologically differ from MUC5AC-positive tubular neoplasms despite morphological resemblance. This article is protected by copyright.

With regard to the main assertion of the author that the case reported by us represents a "collision tumor" and not a "sarcomatoid basal cell carcinoma"), I attach several images from the interface between the basal cell carcinoma (BCC) and the sarcomatoid area. These images prove that there is an unquestionable morphological (Figure 1) and immunohistochemical (Figure 2) transition between both components (basal cell carcinoma and the biphasic sarcomatoid tumor with myoepithelial diffferentiation). Therefore, this is not a collision tumor but a unique example of sarcomatoid BCC in which a biphasic sarcomatoid component with myoepithelial features arises from a BCC.

A large and varied Chilean adult sample (N = 1,272, 60.1% women; age M = 39.94, SD = 17.33) was recruited in face-to-face interviews and online testing. They completed self-reports of the comic styles (the Comic Style Markers) and sociodemographic variables. Overall, small, but meaningful, differences in comic styles were found for the different sociodemographic groups. Men scored higher than women in all comic styles except for benevolent humor, and six styles decreased with age. Having lower education was associated with more cynicism, while the reverse pattern was found for satire and wit. Religious people showed lower scores in four styles than non-religious people, and cynicism was higher in those identifying with left wing rather than right-wing attitudes. The present study thus provides insights into who is more likely to engage in different kinds of humor in their everyday lives. © 2020 Scandinavian Psychological Associations and John Wiley & Sons Ltd.The authors describe a synergistic system for nanoparticle based chiral separation. It is based on the use of a conventional chiral selector hydroxyproyl-β-cyclodextrin and a kind of gold nanoparticle functionalized with D-Penicillamine as an additive. This nanomaterial displays a synergistic effect on the efficiency of the enantioseparation of the chiral drugs amlodipine, tropicamide and ofloxacin. A comparative study on the enantioseparation capability of three separation systems, viz. (a) single hydroxyproyl-β-cyclodextrin system, (b) achiral citrate capped gold nanoparticle/ hydroxyproyl-β-cyclodextrin system, and (c) chiral D-Penicillamine functionalized gold nanoparticle/ hydroxyproyl-β-cyclodextrin system was performed. The results show that the D-Penicillamine functionalized gold nanoparticle/ hydroxyproyl-β-cyclodextrin synergistic system has remarkable superiority. The effects of concentrations of D-Penicillamine functionalized gold nanoparticle and hydroxyproyl-β-cyclodextrin, of buffer pH value and concentration, and of applied voltage on the performance of enantioseparation were investigated.

The aim of the study was to provide objective evidence as to which behavioural endpoint should be used in clinical trials. METHOD Cross-sectional behavioural and demographic data were pooled from four paediatric NF1 tertiary referral centres in Australia and the United States (N=122; 65 males, 57 females; mean age [SD] 9y 2mo [3y], range 3-15y). RESULTS Distributions of SRS-2 and SSIS-RS scores were unimodal and both yielded deficits, with a higher proportion of severely impaired scores on the SRS-2 (16.4%) compared to the SSIS-RS (8.2%). Pearson's product-moment correlations revealed that both questionnaires were highly related to each other (r=-0.72, p less then 0.001) and to measures of adaptive social functioning (both p less then 0.
