Accurate prediction of bleeding risk after coronary artery bypass grafting with dual antiplatelet therapy: A machine learning model vs. the PRECISE-DAPT score.

Background: Dual antiplatelet therapy (DAPT) after coronary artery bypass grafting (CABG), although might be protective for ischemic events, can lead to varying degrees of bleeding, resulting in serious clinical events, including death. This study aims to develop accurate and scalable predictive tools for early identification of bleeding risks during the DAPT period post-CABG, comparing them with the PRECISE-DAPT score..

Uniform anchoring of MoS nanosheets on MOFs-derived CoFeO porous nanolayers to construct heterogeneous structural configurations for efficient and stable overall water splitting.

Rational interfacial engineering and morphology modulation are recognized as effective strategies to modulate the electronic structure and improving the activity of spinel materials. In this paper, we report a strategy of Fe-induced creation of porous nanolayers of CoFeO with unique morphology derived from MOFs by introducing ferrocene, and then constructed CoFeO/MoS heterostructures were fabricated by homogeneously anchoring MoS nanosheets onto the surface of CoFeO. The triple synergistic effect of heterogeneous interfaces, highly active Mo(IV) sites, and unsaturated S effectively accelerates the cycling process between Fe(III)/Fe(II) and Co(III)/Co(II), which in turn enhances the adsorption of reactive intermediates on the active sites, as further corroborates by density functional theory (DFT) calculations.

Enzymolysis Modes Trigger Diversity in Inhibitor-α-Amylase Aggregating Behaviors and Activity Inhibition: A New Insight Into Enzyme Inhibition.

Inhibitors of α-amylase have been developed to regulate postprandial blood glucose fluctuation. The enzyme inhibition arises from direct or indirect inhibitor-enzyme interactions, depending on inhibitor structures. However, an ignored factor, substrate, may also influence or even decide the enzyme inhibition.

Inconsistency between polyphenol-enzyme binding interactions and enzyme inhibition: Galloyl moiety decreases amyloglucosidase inhibition of catechins.

Inhibiting carbohydrate-hydrolyzing enzymes has been considered as an effective approach for controlling starch digestion and postprandial blood glucose level. α-Amylase and amyloglucosidase (AMG) are commonly applied in analysis of starch digestion behaviour. Catechins have been shown with the inhibiting effects on α-amylase.

Soluble dietary fibres decrease α-glucosidase inhibition of epigallocatechin gallate through affecting polyphenol-enzyme binding interactions.

The effects of soluble dietary fibres (SDFs) on α-glucosidase inhibition of EGCG were studied. Three arabinoxylans and polygalacturonic acid (PGA) significantly decreased inhibitory activity of EGCG against α-glucosidase, while two β-glucans hardly affected the inhibition. Although arabinoxylans and PGA weakened the competitive inhibition character of EGCG, they maintained the fluorescence quenching effect of EGCG.

Accurate extraction of the +1 term spectrum with spurious spectrum elimination in off-axis digital holography.

In off-axis digital holography, spatial filtering is a key problem limiting the quality of reconstructed image, especially in the case of spurious spectrum generated by coherent noise in the hologram spectrum. In this paper, a new spatial filtering method with spurious spectrum elimination is proposed. Side band centering judgment is firstly implemented to locate the center point of the +1 term in the hologram spectrum.

α-Amylase inhibition of a certain dietary polyphenol is predominantly affected by the concentration of α-1, 4-glucosidic bonds in starchy and artificial substrates.

To elucidate why the inhibitory activity of one same polyphenol against α-amylase varies in different works. Seven starchy and three artificial substrates, and a polyphenolic competitive inhibitor, tannic acid (TA) were applied to study the enzyme inhibition in different digestion systems. The results showed that the IC values of TA were similar for all starches at the same starch concentration, although there existed difference in starch physiochemical properties, like branching degree, amylose chain distribution, viscosity, and digestion rate.

A Strategy to Design CuMoS@MXene Composite With High Photothermal Conversion Efficiency Based on Electron Transfer Regulatory Effect.

Using photothermal therapy to treat cancer has become an effective method, and the design of photothermal agents determines their performance. However, due to the major radiative recombination of a photogenerated electron in photothermal materials, the photothermal performance is weak which hinders their applications. In order to solve this issue, preventing radiative recombination and accelerating nonradiative recombination, which can generate heat, has been proved as a reasonable way.

RNA-Seq Based Toxicity Analysis of Mesoporous Polydopamine Nanoparticles in Mice Following Different Exposure Routes.

Mesoporous polydopamine nanoparticles (MPDA NPs) are promising nanomaterials that have the prospect of clinical application for multi-strategy antitumor therapy, while the biosecurity of MPDA NPs remains indistinct. Here, transcriptome sequencing (RNA-Seq) was performed to systematically reveal the toxicity of MPDA NPs to five categories of organs after three different exposure routes, including intravenous injection, intramuscular injection, and intragastric administration. Our results uncovered that MPDA NPs could be deposited in various organs in small amounts after intravenous administration, not for the other two exposure routes.

SAIL: a new conserved anti-fibrotic lncRNA in the heart.

Long non-coding RNAs (lncRNAs) account for a large proportion of genomic transcripts and are critical regulators in various cardiac diseases. Though lncRNAs have been reported to participate in the process of diverse cardiac diseases, the contribution of lncRNAs in cardiac fibrosis remains to be fully elucidated. Here, we identified a novel anti-fibrotic lncRNA, SAIL (scaffold attachment factor B interacting lncRNA).

LncRNA ACART protects cardiomyocytes from apoptosis by activating PPAR-γ/Bcl-2 pathway.

Cardiomyocyte apoptosis is an important process occurred during cardiac ischaemia-reperfusion injury. Long non-coding RNAs (lncRNA) participate in the regulation of various cardiac diseases including ischaemic reperfusion (I/R) injury. In this study, we explored the potential role of lncRNA ACART (anti-cardiomyocyte apoptosis-related transcript) in cardiomyocyte injury and the underlying mechanism for the first time.

lncRNA H19 Alleviated Myocardial I/RI via Suppressing miR-877-3p/Bcl-2-Mediated Mitochondrial Apoptosis.

Ischemic cardiac disease is the leading cause of morbidity and mortality in the world. Despite the great efforts and progress in cardiac research, the current treatment of cardiac ischemia reperfusion injury (I/RI) is still far from being satisfactory. This study was performed to investigate the role of long non-coding RNA (lncRNA) H19 in regulating myocardial I/RI.

LncRNA PCFL promotes cardiac fibrosis via miR-378/GRB2 pathway following myocardial infarction.

Long noncoding RNAs (lncRNAs) are a class of novel molecular regulators in cardiac development and diseases. However, the role of specific lncRNAs in cardiac fibrosis remains to be fully explored. The aim of the present study was to investigate the effects and underlying mechanisms of lncRNA PCFL (pro-cardiac fibrotic lncRNA) on cardiac fibrosis after myocardial infarction (MI).
