Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of advanced chronic (ACLD). Portal hypertension drives hepatic decompensation and best diagnosed by venous pressure gradient (HVPG) measurement. Here, we investigate the prognostic value HVPG in MASLD-related compensated ACLD (MASLD-cACLD).
Abstract Electrografting is a powerful and versatile technique for modifying decorating conducting surfaces with organic matter. Mainly based on the electro‐induced polymerization of dissolved electro‐active monomers metallic or semiconducting surfaces, it finds applications in various fields including biocompatibility, protection against corrosion, lubrication, soldering, functionalization, adhesion, template chemistry. Starting from experimental observations, this Review highlights...
A central paradigm that underpins our understanding of the interaction proteins with solid surfaces is protein adsorption leads to changes in secondary structure. The bound tend denature, and these non-native, adsorbed structures are likely stabilized through loss α-helices concomitant formation intermolecular β-sheets. goal this work critically assess impact behavior has on desorption, where irreversible conformational might lead aggregation or result other forms instability. adsorption,...
Epidemiologic parameters, virologic characteristics and frequency of HLA class II DR DQ antigens were compared between 63 subjects with spontaneous hepatitis C virus clearance (group 1) 282 patients chronic active infection 2). DRB1*1101 moreover DQB1*0301 alleles more frequent in group 1 than 2 (33.8% vs. 14.7% 64.4% 28.6%; P=0.012 P=0.003, respectively). The DQB1*02 was lower (25.4% 49%; P=0.04). No difference observed viral genotype distribution 2. Univariate analysis showed that female...
The aim of this work is to present an interaction reactor which allows us build very thin organic coatings on metallic substrates. This coupled analytic device further enables investigation the interfacial region by very-surface-sensitive analytical means. use such integrated installation makes it possible follow growth step and focus nature chemical structure that identified in between a well-defined polymer phase atomically clean substrate. As illustration we compare behavior PA-6,6 copper...
Self-assembled monolayers of 1,4-diisocyanobenzene on gold were used to bind ruthenium phthalocyanines the surface by axial ligation macrocycle with isocyanide groups pointing out from SAM. The SAM and RuPc-1,4-diisocyanobenzene bilayer characterized ellipsometry, IRRAS, XPS, SPM. grafting RuPc is stable. thickness film increases 10 15 Å upon ligation. IRRAS reveals that both ends are affected N⋮C metal interaction occurring at other end. XPS indicates each covers ∼12 molecules in bilayer.
Polyimides have been extensively studied in view of their wide industrial applications. Adhesion to a substrate is essential for normal operation devices. This problem often solved by the use an adhesion promoter on surface interest. A surface-sensitive technique such as XPS has proved be powerful analytical tool analysis polymer/substrate interface. In present paper, interfaces SiO2/γ-aminopropyltriethoxysilane (γ-APS)/Pyralin system investigated at precured stage. detailed molecular...
Although an efficient DFT method using the generalized transition-state model to calculate core−electron binding energies had been successfully applied over 200 cases, with average absolute deviation of only 0.21 eV from experiment, a new ΔEKS(PW86−PW91)/cc-pCVTZ based on total Kohn−Sham energy difference was recently developed. Not error-free, but also for 32 cases studied found be 0.15 eV. In this study, we first confirm excellent performance such ΔEKS approach 46 result that experiment 78...
The possibility of chemically grafting polyacrylonitrile onto transition metal electrodes via electropolymerization leads to promising applications in the fields corrosion protection or surface functionalization. initial step electrografting mechanism is adsorption acrylonitrile monomer on from solution.

We present a quantum chemical investigation of core−electron binding energies (CEBEs) for small hydrogen-bonded clusters involving water, carboxylic acids, and formamide. Our DFT ΔEKS method well reproduces scarce experimental CEBEs available in the literature, especially recent ones on gas phase water clusters. This shows that hydrogen bonds are actually detectable using XPS, even though it is core level probing technique. may be major interest bonding detection very thin layers, which few...

The application of single step or multiple anodic potential steps to highly concentrated solutions N-vinyl-2-pyrrolidone leads the formation poly(N-vinyl-2-pyrrolidone) (or PVP) films on platinum electrodes. These are insoluble in a good solvent commercial polymer. Multiple yield thicker than step. Moreover, PVP film thickness is maximum for working amplitude 1.7 V. Above this potential, polymer deteriorates by oxidation. In situ quartz crystal microbalance measurements show that mechanism...
