Enalomics: A Mass Spectrometry-Based Approach for Profiling, Identifying, and Semiquantifying Enals in Biological Samples.

Human cells generate a bulk of aldehydes during lipid peroxidation (LPO), influencing critical cellular processes, such as oxidative stress, protein modification, and DNA damage. Enals, highly reactive α,β-unsaturated aldehydic metabolites, are implicated in various human pathologies, especially neurodegenerative disorders, cancer, and cardiovascular diseases. Despite their importance, endogenous enals remain poorly characterized, primarily due to their instability and low abundance.

Construction of Loop Polyzwitterion Brushes on PET Sheets via the Chain-End Closure Strategy To Improve Antifouling and Hemocompatible Properties.

Steric stabilization and lubrication give loop polymer brushes enhanced antifouling properties. In the study, linear zwitterionic poly(NMASMCMS) brushes were first constructed on a poly(ethylene terephthalate) (PET) surface through surface-initiated reversible addition-fragmentation chain-transfer (SI-RAFT) polymerization. The tethered linear brushes on sheets were then thiolated with ethanolamine, followed by oxidation to form loop brushes.

The catalytic hairpin assembly (CHA) strategy was integrated with superparamagnetic FeO nanoparticle clusters (NCs) to enhance sensitivity.

Early activity after strong sutures helps to tendon healing in a rat tendon rupture model.

The purpose of this study was to investigate the effect of different times return to activity on tendon healing after Double Kessler method suture in rats with Achilles tendon rupture.

A feeding-induced myokine modulates glucose homeostasis.

Maintaining blood glucose homeostasis during fasting and feeding is crucial for the prevention of dysregulation that can lead to either hypo- or hyperglycaemia. Here we identified feimin, encoded by a gene with a previously unknown function (B230219D22Rik in mice, C5orf24 in humans), as a key modulator of glucose homeostasis. Feimin is secreted from skeletal muscle during feeding and binds to its receptor, receptor protein tyrosine kinase Mer (MERTK), promoting glucose uptake and inhibiting glucose production by activation of AKT.

Serum inflammation-related proteins in a acute compartment syndrome rat model.

We aim to explore variations of serum inflammation-related proteins in an acute compartment syndrome (ACS) rat model. We collected serum from 25 healthy Sprague-Dawley rats (control group, CG) and 50 rats with tibial fractures, including 25 rats with ACS (ACS group, AG), and 25 rats without ACS (fracture group, FG). Ten samples per group were randomly chosen for proximity extension assay analysis of 92 inflammation-related proteins, and all samples were verified by enzyme-linked immunosorbent assays.

Herein, we introduce an in situ growth strategy for fabricating two-dimensional heterojunctions between indium porphyrin metal-organic framework (In-MOF) and single-layer graphene oxide (GO). Upon illumination, the In-MOF/GO heterostructure facilitates a tandem CO capture and photocatalytic reduction on its hydroxylated In-node, prioritizing the reduction of dilute CO even in the presence of air-level O.

General synthesis of neighboring dual-atomic sites with a specific pre-designed distance via an interfacial-fixing strategy.

A potential non-precious metal catalyst for oxygen reduction reaction should contain metal-N moieties. However, most of the current strategies to regulate the distances between neighboring metal sites are not pre-designed but depend on the probability by tuning the metal loading or the support. Herein, we report a general method for the synthesis of neighboring metal-N moieties (metal = Fe, Cu, Co, Ni, Zn, and Mn) via an interfacial-fixing strategy.
