In addition, a marginally significant association between questionnaire scores (PSWQ, ASI) in healthy participants and DNMT3B rs2424932 was detected, again with the minor allele conveying a protective effect. The present results suggest a possible minor role of DNMT3A and DNMT3B gene variation in conveying resilience towards anxiety disorders. As the observed associations indicated a protective effect of two SNPs particularly with pathological worry, future studies are proposed to explore these variants in generalized anxiety disorder rather than panic disorder.There are contradictory publications and reports regarding the dependence liability of the 3-hydroxy-benzo-1,4-diazepine derivative lormetazepam, one of the most often prescribed hypnotic benzodiazepines which is now also available as an intravenous (i.v.) product for anesthetists. The author was involved in the preclinical and subsequently in the clinical development and post-marketing surveillance of lormetazepam. Here, he reviews the published and unpublished data about lormetazepam dependence and proposes explanations for contradictory views from other authors. On this basis and in contrast to class labeling from regulatory bodies and WHO, the author comes to the conclusion that use of lormetazepam definitely carries a lower risk of inducing dependence and causing abuse than most other benzodiazepines. This applies as well to Sedalam®, the new i.v. application form of lormetazepam, which is much better tolerated than propofol. Because of its pharmacokinetic properties and because all its effects can be fully antagonized with the benzodiazepine antagonist flumazenil, this innovative intravenous application form of lormetazepam provides an excellent method for premedication, symptomatic treatment of excitation and anxiety in the context of surgical or diagnostic procedures including outpatient interventions and for basic sedation during anesthesia.Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, and most patients die within one year after diagnosis. This cancer is resistant to almost all current therapies, so there is an urgent need to identify novel druggable targets. Ubiquitin-specific protease 7 (USP7) is a deubiquitinase that functions in carcinogenesis, but its role in PDAC is unknown. Our experiments indicated that several subtypes of PDAC cells are sensitive to USP7 inhibition. In particular, pharmaceutical inhibition of USP7 by the small molecule P22077 attenuated PDAC cell growth and induced cell death in vitro and in vivo. Pharmaceutical inhibition of USP7 in P22077-resistant PDAC cells allowed them to overcome chemoresistance. Genetic silencing experiments supported the importance of USP7 in the pathogenesis of PDAC. In particular, genetic disruption of USP7 greatly reduced cell proliferation and chemoresistance in vitro and prevented PDAC growth in vivo. Protein profiling by mass spectrometry (MS) indicated USP7 was associated 4 ontology terms translation, localization and protein transporting, nucleotide or ribonucleotide binding, and ubiquitin-dependent catabolic processes. Puromycin labeling indicated that P22077 greatly reduced protein synthesis, and transcriptional analysis indicated that P22077 significantly altered the extracellular space matrix. In summary, we provided multiple lines of evidence which indicate that USP7 plays a critical role in PDAC, and may therefore be a suitable target for treatment of this cancer.Background Metastatic pancreatic tumors from lung cancer (MPTLC) constitute 3% of all metastatic pancreatic tumors. We present an extremely rare case of cystic MPTLC that was difficult to distinguish from intraductal papillary mucinous neoplasm (IPMN). Case presentation The patient was a 74-year-old woman who underwent lobectomy of lung cancer 2 years before presentation to our hospital. She was referred to our department for resection of cystic pancreatic tumors, which were diagnosed as IPMN with high-risk stigmata. selleck chemicals Abdominal computed tomography (CT) showed a 37-mm-wide cystic tumor with a contrasted solid nodule in the pancreatic head and a 17-mm-wide cystic tumor in the pancreatic tail. We performed a total pancreatectomy for these lesions. According to histopathological and immunohistochemical findings, the tumors were diagnosed as metastatic pancreatic tumors from lung cancer. Conclusion In this case, the cystic morphology was formed by eosinophilic secretions from tumor cells, and it was difficult to distinguish from IPMN with high-risk stigmata. We consider this case, based on the variable clinical findings, an extremely rare variant of MPTLC.Purpose Pancreatic neuroendocrine neoplasms (PNENs) are a group of clinically rare and heterogeneous tumors of the pancreas. Currently there are no studies investigating the gender difference in PNEN susceptibility. Thus, the purpose of this study was aimed at examining how gender shapes risk factors, clinicopathological features, and comorbidities in PNENs. Methods The study design consisted of an Italian multicenter, retrospective study. The study included all consecutive patients with PNENs followed at the participating centers. Two hundred and twenty-nine patients (105 males,124 females, age 54 ± 0.98 years) with PNENs were enrolled at the participating centers. The clinicopathological features (age, gender, BMI, histology, tumor size, tumor grade, distant metastasis, hormonal function, and diagnostic circumstances), comorbidities (cardiovascular diseases (CVD), pancreatitis, type 2 diabetes (T2DM), and potential risk factors (smoking and drinking) were included in the analysis. Results Females were slightly prevalent (54.15%). PNENs were diagnosed at younger age in females compared to males (p = 0.04). The prevalence of CVD was significantly higher in males than in females (p = 0.006). In the female group, the presence of T2DM was significantly associated with higher tumor grade (p = 0.04) and metastatic disease (p = 0.02). The proportion of smokers and alcohol drinkers was significantly higher in the male group (p less then 0.001). No significant gender differences were detected regarding the other parameters included in the analysis. Conclusions This study has identified gender differences of PNENs in terms of age at diagnosis, associated comorbidities, and potential risk factors. A gender-tailored approach could become a potential strategy to better understand the natural history of PNENs and improve the effectiveness of PNENs clinical management.
