Who should be screened for colorectal cancer and how can it be prevented more effectively?

In this editorial, we comment on the article published by Agatsuma in a recent issue of the (2024; 30: 1368-1376). We firmly concur with Agatsuma regarding the vital significance of colorectal cancer (CRC) screening as a public health strategy to diminish disease burden. Individuals exposed to risk factors for CRC, those with comorbid conditions, and those with limited health literacy should undergo screening.

Cumulative effects of excess high-normal alanine aminotransferase levels in relation to new-onset metabolic dysfunction-associated fatty liver disease in China.

Background: Within the normal range, elevated alanine aminotransferase (ALT) levels are associated with an increased risk of metabolic dysfunction-associated fatty liver disease (MAFLD).

Aim: To investigate the associations between repeated high-normal ALT measurements and the risk of new-onset MAFLD prospectively.

Methods: A cohort of 3553 participants followed for four consecutive health examinations over 4 years was selected.

Robust, Sprayable, and Multifunctional Hydrogel Coating through a Polycation Reinforced (PCR) Surface Bridging Strategy.

The sprayable hydrogel coatings that can establish robust adhesion onto diverse materials and devices hold enormous potential; however, a significant challenge persists due to monomer hydration, which impedes even coverage during spraying and induces inadequate adhesion post-gelation. Herein, a polycation-reinforced (PCR) surface bridging strategy is presented to achieve tough and sprayable hydrogel coatings onto diverse materials. The polycations offer superior wettability and instant electrostatic interactions with plasma-treated substrates, facilitating an effective spraying application.

A pDNA/rapamycin nanocomposite coating on interventional balloons for inhibiting neointimal hyperplasia.

Drug-coated balloon (DCB) is a therapeutic method that can effectively deliver antiproliferative drugs such as paclitaxel and rapamycin (RAPA) with no permanent implants left behind. However, delayed reendothelialization due to the toxicity of the delivered drugs leads to poor therapeutic effects. Here, we propose a new design of DCB coating, which incorporates both vascular endothelial growth factor (VEGF)-encoding plasmid DNA (pDNA) that can promote endothelial repair and RAPA into protamine sulfate (PrS).

Mir-22-incorporated polyelectrolyte coating prevents intima hyperplasia after balloon-induced vascular injury.

Drug-coated balloons (DCBs) offer potential to deliver drugs to treat coronary lesions but without leaving permanent implants behind. Paclitaxel and sirolimus are anti-proliferation drugs that are commonly used in commercially available DCBs. However, these drugs present significant cytotoxicity concern and low efficacy .

The substrate stiffness at physiological range significantly modulates vascular cell behavior.

Changes in the stiffness of the cellular microenvironment are involved in many pathological processes of blood vessels. Substrate stiffness has been shown to have extensive effects on vascular endothelial cells (VECs) and vascular smooth muscle cells (VSMCs). However, the material stiffness of most previously reported in-vitro models is ranging from ~100 kPa to the magnitude of MPa, which does not match the mechanical properties of natural vascular tissue (10-100 kPa).

The influence of substrate stiffness on osteogenesis of vascular smooth muscle cells.

Vascular stiffening occurs with advanced age and under pathological conditions such as vascular calcification, during which the osteogenesis of smooth muscle cells (SMCs) plays a key role. However, whether the stiffness of cellular microenvironment influences osteogenic responses in vascular SMCs is not well understood. Here, we cultured SMCs on the poly(dimethylsiloxane) (PDMS) substrates with varying stiffness from 0.

Biodegradable phosphorylcholine copolymer for cardiovascular stent coating.

Phosphorylcholine (PC) based polymer coatings with excellent biocompatibility have shown successful commercialization in drug-eluting stents. However, poor degradability represents a challenge in the application of biodegradable stents. Herein, a biodegradable phosphorylcholine copolymer is developed based on one-step radical ring-opening polymerization (RROP).

A facile approach to construct hybrid multi-shell calcium phosphate gene particles.

The calcium phosphate (CaP) particles have attracted much attention in gene therapy. How to construct stable gene particles was the determining factor. In this study, hybrid multi-shell CaP gene particles were successfully constructed.
