A Systematic Method to Detect Next-Generation Sequencing-Based Microsatellite Instability in Plasma Cell-Free DNA: plasmaMSI.

Microsatellite instability (MSI) detection using tumor tissue is a well-established prognostic and predictive biomarker for certain types of cancers. However, tumor tissue samples are less convenient to obtain than blood plasma samples. The main challenge facing next-generation sequencing-based MSI detection in blood plasma samples is the ultralow signal/noise ratio in plasma cell-free DNA (cfDNA).

Hydrated Calcium Silicate Erosion in Sulfate Environments a Molecular Dynamics Simulation Study.

To investigate the micro-mechanism of the erosion of hydrated calcium silicate (C-S-H gel) in a sulfate environment, a solid-liquid molecular dynamics model of C-S-H gel/sodium sulfate was developed. This model employs molecular dynamics methods to simulate the transport processes between C-S-H gel and corrosive ions at concentrations of 5%, 8%, and 10% sodium sulfate (NaSO), aiming to elucidate the interaction mechanism between sulfate and C-S-H gel. The micro-morphology of the eroded samples was also investigated using scanning electron microscopy (SEM).

Advances in Molecular Dynamics-Based Characterization of Water and Ion Adsorption and Transport in C-S-H Gels.

A general system for targeting MHC class II-antigen complex via a single adaptable loop.

Major histocompatibility complex class II (MHCII) bound to a peptide antigen mediates interactions between CD4 T cells and antigen-presenting cells. Targeting peptide-MHCII with T cell antigen receptors (TCRs) and TCR-like antibodies has shown promise for autoimmune diseases and microbiome tolerance. To develop a general targeting approach, we introduce targeted recognition of antigen-MHC complex reporter for MHCII (TRACeR-II) for the rapid development of peptide-specific MHCII binders.

Durability of a Metakaolin-Incorporated Cement-Based Grouting Material in High Geothermal Tunnels.

To improve the durability of cement-based grout in high geothermal tunnel grouting projects, metakaolin was incorporated to replace 8% of the cement. The permeability, chloride penetration, and sulfate and carbonate erosion tests were carried out on the grout cured at varying temperatures (20, 30, 40, 50, and 60 °C). It was shown that with the increase in curing temperature, the impermeability and resistance to chloride penetration initially increased and then decreased, reaching the highest values at 40 °C.
