Control of pH gradient profile at the electrode-electrolyte interfaces allows the control of the enzymatic PEG-hydrogel polymerization. By tuning the solution pH, buffer capacity, and the applied current, the extent of the local inhibition and confinement of the Factor XIII-mediated polymerization of PEG are controlled. This technology opens new perspectives for the production of 3D-structured biological microenvironments.

We aimed to assess the impact of splicing variants reported in our laboratory to gain insight into their clinical relevance. A total of 108 consecutive individuals, for whom 113 splicing variants had been reported, were selected for RNA-sequencing (RNA-seq), considering the gene expression in blood. A protocol was developed to perform RNA extraction and sequencing using the same sample (dried blood spots, DBS) provided for the DNA analysis, including library preparation and bioinformatic pipeline analysis.

Today, weed control in agricultural systems is largely based on the use of synthetic pesticides. However, the use of these compounds is increasingly controversial among farmers and consumers, who point to their harmful properties for human health and the environment. In this context, the development of eco-friendly agricultural approaches and practices is becoming essential, and allelopathy represents a promising solution.

This study investigates the effect of 100 mg L thymol treatment on the quality of post-harvest peppers stored at 10 °C. The results showed that thymol treatment significantly reduced decay rate, reactive oxygen species (ROS) accumulation, and saturated fatty acid levels in peppers. Moreover, unsaturated fatty acids, non-enzymatic antioxidants, and antioxidant enzyme levels increased after treatment.

Background: Rho GTPases are essential regulators for cellular movement and intracellular membrane trafficking. Their enzymatic activities fluctuate between active GTP-bound and inactive GDP-bound states regulated by GTPase activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs). Arhgap39/Vilse/Porf-2 is a newly identified GAP.

The process of regenerating bone injuries in diabetic presents significant challenges because lysine oxidase (LOX), a key catalytic enzyme for collagen cross-linking, is inhibited in hyperglycemia. The supplementation of LOX is constrained by inadequate sources and diminished enzymatic activity, necessitating the development of effective alternatives for enhancing bone regeneration in diabetes. Herein, we reported a lysyl oxidase nanozyme (LON), derived from the catalytic domain of LOX.
