The cytoplasm exhibits viscoelastic properties, displaying both solid and liquid-like behavior, and can actively regulate its mechanical attributes. The cytoskeleton is a major regulator among the numerous factors influencing cytoplasmic mechanics. We explore the interdependence of various cytoskeletal filaments and the impact of their density on cytoplasmic viscoelasticity.

Sepsis-associated encephalopathy (SAE) is a severe and frequent septic complication, characterized by neuronal damage as key pathological features. The astrocyte-microglia crosstalk in the central nervous system (CNS) plays important roles in various neurological diseases. However, how astrocytes interact with microglia to regulate neuronal injury in SAE is poorly defined.

During the implantation process of cardiovascular implants, vascular damage caused by inflammation occurs, and the inflammatory process is accompanied by oxidative stress. Currently, carbon monoxide (CO) has been demonstrated to exhibit various biological effects including vasodilatation, antithrombotic, anti-inflammatory, apoptosis-inducing and antiproliferative properties. In this study, hemoglobin/epigallocatechin-3-gallate (EGCG) core-shell nanoparticle-containing coating on stainless steel was prepared for CO loading and inflammation modulation.

Human citrate synthase (hCS) was kinetically characterized through full progress curve kinetic modelling using kinetic simulation, global fitting of the direct AcCoA to CoA transition, and a coupled thiol probe reaction to better determine the kinetics with low substrate concentration. Our analysis provides one of the most rigorous kinetic analyses of any citrate synthase ruling out the need to invoke complex cooperative mechanisms to explain progress curve data. Furthermore, we collected and modeled stopped-flow pH-dependent kinetic data with CoA and popular thiol probes such as Ellman's reagent (DTNB) and 4,4'-Dithiodipyridine (DPS), providing the opportunity for detailed kinetic simulations using these thiol probes with CoA producing enzymes.
