In recent years, the introduction of mRNA vaccines for SARS-CoV2 and RSV has highlighted the success of the mRNA technology platform. Designing mRNA sequences involves multiple components and requires balancing several parameters, including enhancing transcriptional efficiency, boosting antigenicity, and minimizing immunogenicity. Moreover, changes in the composition and properties of delivery vehicles can also affect vaccine performance.

Deep ultraviolet (DUV) photodetection usually relies on wide-bandgap semiconductors, which however face challenges in material growth and doping processes. In this work, we proposed and validated a photodetection scheme based on tunneling barrier modulation, achieving highly sensitive DUV photodetection. Using a two-dimensional van der Waals heterostructure, the device integrates MoS as the transporting layer for its high carrier mobility and low dark current, few-layered graphene (FLG) as the photon absorption layer, and hexagonal boron nitride (hBN) as the dielectric barrier.

The increased prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and its profound implications for global health have sparked extensive research endeavors aimed at developing potential diagnostic methods for this condition. Despite the achievements in defining various environmental factors and genetic predispositions linked to MASLD, diagnosis and clinical staging of the disease remain challenging. Recently, extracellular vesicles (EVs) have garnered considerable attention owing to their roles in metabolic dysfunctions and their potential as biomarkers for various conditions.

The neuronal death and motor dysfunction resulting from CIS are primarily attributed to the induction of PARthanatos in neurons at the site of ischemia. Blocking parthanatos is a promising treatment for CIS.

Recent studies suggest that androgen receptor (AR) signaling plays a role in regulating CD8 T-cell function, implying that 5α-reductase inhibitors (5-ARIs), which lower androgen activity, could enhance antitumor immunity and improve clinical outcomes in patients receiving immunotherapy. This study retrospectively investigates the impact of a history of 5-ARI use (≥12 months) on the efficacy of ICIs in mRCC.

Titanium-based alloys, especially Ti6Al4V, are applied as artificial bone grafts due to their favorable mechanical property and biocompatibility, assisted by personalized customization of 3D-printing to completely match with the bone defect. However, their bioinert peculiarity restricts osteointegration at the interface between bone and titanium-based implants and bone growth into porous titanium-based scaffolds, for lack of bone regeneration with the aid of blood vessels and neural networks.
