Background: Prosthetic socket is a key component of the prosthesis for clinical application; its performance directly affects the adaptation of the residual limb to the prosthetic socket. There are long-term and short-term volume fluctuation of the residual limb. The volume fluctuation of the residual limb will lead to the pressure mismatch at the interface of the residual limb and the prosthetic socket, which will cause a series of skin and fit problems.

It requires intermolecular interaction patterns to be correctly described and, more importantly, the dynamic behaviors of macrocyclic hosts to be accurately modeled. Pillar[]arenes as a crucial family of macrocycles play a critical role in host-guest chemistry and biomedical applications.

Nanoscale air channel transistors (NACTs) present a promising alternative, leveraging their vacuum-like channel and Fowler-Nordheim tunneling characteristics. In this study, a novel circular gate NACT (CG-NACT) is purposed, fabricated on a 4-inch silicon-based wafer using a CMOS-compatible process.

Nevertheless, PD-L1 positive senescent tumor cells resist immune clearance and possess the ability to secret various cytokines and inflammatory factors that stimulate the growth of tumor cells. Consequently, drugs capable of both triggering senescence in tumor cells and concurrently diminishing the expression of PD-L1 to counteract immune evasion are urgently needed.

Despite its immense potential in resolving the cell fate determination and genealogy within an organism, existing implementations of this technology suffer from limitations in recording capabilities and considerable barcode dropout. Here, we introduce DuTracer, a versatile tool that utilizes two orthogonal gene editing systems to record cell lineage history at single-cell resolution in an inducible manner.

This study addresses the challenge of controlling Cas12a activity, especially in the context of nucleic acid detection where the inherent incompatibility between isothermal amplification and CRISPR reactions complicates accurate diagnostics. An RNA G-quadruplex (RG4) structure at the 5' end of crRNA is introduced to modulate Cas12a activity accurately without the need for chemical modifications.

Metabolic reprogramming is a crucial mechanism for fibrosis. However, how the metabolic rewiring shifts the ECM homeostasis toward overaccumulation remains unclear.
View Article and Find Full Text PDFType-I photosensitizers (PSs) are among the most potential candidates for photodynamic therapy (PDT), as their low dependence on oxygen endow them with many advantages for treating hypoxic tumor. However, most of the reported type-I PSs have a contingency of molecular design, because electron transfer (ET) reaction is more difficult to achieve than energy transfer (EET) process. Therefore, it is urgent to understand molecular design mechanisms for type-I PSs.
View Article and Find Full Text PDFBurn injuries often cause prolonged oxidative stress and inflammatory pain due to an initial increase in inflammatory responses, consequently exacerbating depressive disorders and severely impairing patients' quality of life. The primary function of traditional burn dressings is to prevent infection and facilitate tissue repair. However, these dressings are not intended for the inflammatory pain and depression that often occur during recovery.

Despite new developments in nanotechnology in the treatment of PD, in-depth exploration of their biological effects, in particular, the specific mechanisms of inflammation inhibition are lacking. Herein, using the stable cascade catalysis channel formed by polydopamine (PDA), imidazole groups, and Cu ions, a microgel system comprising functional monomers [superoxide dismutase (SOD) with double bonds, PDA, 2-methacryloyloxy ethyl phosphorylcholine (MPC), and Cu ions] is proposed for managing PD.
View Article and Find Full Text PDFAneuploidy eggs are a common cause of human infertility, spontaneous abortion, or trisomy syndromes. The spindle assembly checkpoint (SAC) plays a crucial role in preventing aneuploidy in oocytes, yet it is unclear if additional mechanisms exist to ensure oocyte adherence to this checkpoint. It is now revealed that the microtubule-associated protein NUSAP can prevent oocytes from evading the SAC and regulate the speed of the cell cycle.

However, current methods for loading drugs into exosomes are inefficient and cost-prohibitive for practical application. In this study, boron clusters are mixed with doxorubicin (DOX) and exosomes, enabling the efficient encapsulation of DOX into exosomes through a superchaotropic effect.

Self-renewal and strong tumourigenic capacity of glioblastoma stem cells (GSCs) at the narrow margin of the incision are essential factors driving tumor secondary strikes. Currently, the challenges in treating postoperative residual GSCs are mainly due to the lack of materials for incision and GSCs targeting.

Herein, unique Ru-B-Cr moieties have been constructed in RuO nanofibers (NFs) to activate Ru sites for water electrolysis, which overcomes the bottleneck of RuO-based catalysts usually possessing low activity for the hydrogen evolution reaction (HER) and poor stability for the oxygen evolution reaction (OER). The fabricated Cr, B-doped RuO NFs exhibit low overpotentials of 205 and 379 mV for acidic HER and OER at 1 A cm with outstanding stability lasting 1000 and 188 h, respectively.
