A 52-year-old female was referred for a study of a left intrahepatic bile duct dilation with an initial suspicion of Klatskin. Analytically, there was no cholestasis and tumor markers were negative. On echoendoscopy, there was dilation of the intrahepatic bile duct to the confluence at the level of the left hepatic lobe, with no evidence of a lesion that could be biopsied by fine needle aspiration (FNA).Pyroptosis is an inflammatory cell death process that is dependent on caspase. Pyroptosis is a specific form of programmed cell death with the morphological characteristics of formation of pores on the cell membrane, cell swelling, and rupture of the plasma membrane. selleck inhibitor Recent studies have demonstrated that pyroptosis plays an important role in the occurrence and development of liver diseases. Here, we focus on the mechanisms of pyroptosis, as well as on the relationship between pyroptosis and liver diseases.Œnology in its scientific dimension makes it possible to bring together a large community of researchers from various fields of expertise to share their knowledge and experience around wine. Two international meetings, the 11th International Œnology Symposium and In Vino Analytica Scientia 2019, were exceptionally held in the context of a joint organization under a common title ŒnoIVAS 2019, in Bordeaux, France, in June 2019. The conferences were attended by 350 delegates, from 24 countries, who shared different aspects of wine and spirits research, with 7 invited lectures, 71 oral communications, and over 200 posters. This special issue is a collection of full papers from a selection of contributed oral presentations and posters presented at the conference.Brunauer-Emmett-Teller (BET) surface area obtained by nitrogen adsorption is a commonly adopted value to characterize the specific surface area for porous materials. In the BET method, the widely applied cross-sectional area of nitrogen is 16.2 Å2, which has been found to be an oversimplified assumption. The adsorption isotherms of nitrogen simulated with the 2CLJ (Lennard-Jones) + 3q molecular model at 77 K was utilized to determine the cross-sectional area and its behavior as a function of pressure, pore size, and solid affinity. The cross-sectional area shows a negative relation with the pressure and varies with pore size and solid affinity. The overestimation of the BET surface area might arise from the inaccurately determined monolayer adsorption capacity and the cross-sectional area.Molecular dynamic (MD) simulations are an important tool for studying protein aggregation processes, which play a central role in a number of diseases including Alzheimer's disease. However, MD simulations produce large amounts of data, requiring advanced methods to extract mechanistic insight into the process under study. Transition networks (TNs) provide an elegant method to identify (meta)stable states and the transitions between them from MD simulations. Here, we apply two different methods to generate TNs for protein aggregation Markov state models (MSMs), which are based on kinetic clustering the state space, and TNs using conformational clustering. The similarities and differences of both methods are elucidated for the aggregation of the fragment Aβ16-22 of the Alzheimer's amyloid-β peptide. In general, both methods perform excellently in identifying the main aggregation pathways. The strength of MSMs is that they provide a rather coarse and thus simply to interpret picture of the aggregation process. Conformation-sorting TNs, on the other hand, outperform MSMs in uncovering mechanistic details. We thus recommend to apply both methods to MD data of protein aggregation in order to obtain a complete picture of this process. As part of this work, a Python script called ATRANET for automated TN generation based on a correlation analysis of the descriptors used for conformational sorting is made publicly available.Svalbardines A and B (1 and 2) and annularin K (3) were isolated from cultures of Poaceicola sp. E1PB, an endophyte isolated from the petals of Papaver dahlianum from Svalbard, Norway. Svalbardine A (1) is a pyrano[3,2-c]chromen-4-one, a new analogue of citromycetin. Svalbardine B (2) displays an unprecedented carbon skeleton based on a 5'-benzyl-spiro[chroman-3,7'-isochromene]-4,8'-dione core. Annularin K (3) is a hydroxylated derivative of annularin D. The structure of these new polyketides, along with those of known compounds 4-6, was established by spectrometric analysis, including extensive ESI-CID-MS n processing in the case of svalbardine B (2).A neural network based quasi-diabatic potential energy matrix Hd that describes the photodissociation of formaldehyde involving the two lowest singlet states S0 and S1 is constructed. It has strict complete nuclear permutation inversion symmetry encoded and can reproduce high level ab initio electronic structure data, including energies, energy gradients, and derivative couplings, with excellent accuracy. It has been fully saturated in the configuration space to cover all possible reaction pathways with a trajectory-guided point sampling approach. This Hd will not only enable the accurate full-dimensional dynamic simulations of the photodissociation of formaldehyde involving S0 and S1 but also provide a crucial ingredient for incorporating spin-orbit couplings into a diabatic framework, thus ultimately enabling the study of both internal conversion and intersystem crossing in formaldehyde on the same footing.The monitoring of the emerging contaminant, microplastics, in the environment, in water supply, and for food safety is of major interest to science, consumers, and governments. While the chemical analysis of these particles is considered mandatory, a rapid and reliable method for the determination of particle sizes, shapes, and numbers is missing, as existing methods are not fitting into current laboratory measurement routines. In this study, we present an approach for circumventing these issues through the application of quantum cascade laser-based microscopy combined with an automated data analysis. This method allows the measurement of an area of 144 mm2 in 36 min, with a pixel resolution of 4.2 μm, which is an appropriate timeframe and spatial resolution for routine measurements. The performance was compared to the existing state-of-the-art Fourier transform infrared microscopy analyses. Further, the application of the method on various environmental samples was investigated to examine its capacity to provide number and variety of present particles.
