The complexity of serum constituents and the lack of knowledge on biomarkers bring obstacles for reliable cancer screening with the limited information obtained by surface-enhanced Raman scattering (SERS) on a single substrate. We report here an extremely high-accurate approach for cancer screening by biomarker-free serum-SERS technique which employs three principal SERS substrates that are of specially designed surface properties. With three substrates rich information on serum can be obtained from SERS spectra, of which quadratic discriminant analysis (QDA) yields excellent classifications of serum samples independently.

Silk microfiber scaffolds have garnered increasing interest due to their outstanding properties, with degumming being the process used to extract the sericin from the cocoon. In the present study, an attempt to tune the biodegradation period of silk through degumming with various sodium borohydride (NaBH) concentrations and degumming times was studied. We considered the process, the number of baths used, and the salt concentration.

Rational control over the morphologies of supramolecular assemblies for asymmetric catalysis with enhanced enantioselectivity represents a pivotal challenge in the realm of synthetic chemistry and material technology. Herein, Cu(II) ion-mediated supramolecular nanostructures assembled from chiral amino acid-based amphiphiles (l/d-AlaC) are fabricated as chiral catalysts for Diels-Alder cycloaddition between aza-chalcone and cyclopentadiene. In particular, compared with the supramolecular nanosheet formed by l/d-AlaC without Cu(II) ions, we found that the l/d-alanine chiral amphiphile can form supramolecular nanotubes with a multilayer structure and with the thickness of the tubular wall about 15 nm through the transition from a nanoribbon to tubular structure in the presence of Cu(II) ions.

growth of MnO nanoparticles (NPs) onto chiral /-polyaniline (/-PANI) scaffolds efficiently regulates the supramolecular chirality, making them function as chiral nanozymes for controllable enantioselective catalysis. Compared with the loaded MnO NPs onto /-PANI scaffolds, the enantioselectivity of the growth system is significantly enhanced due to the stronger bonding between catalytic centers and supramolecular scaffolds.

The STING pathway plays a critical role in tumor immunosurveillance. However, the precise mechanisms by which STING regulates gamma delta (γδ) T cell function during tumor progression remain unclear. Herein, we find that tumor-derived cyclic GMP-AMP (cGAMP) activates a distinct STING pathway by inducing TBK1-mediated phosphorylation of Eomes in γδ T cells during the early stage of tumor development is demonstrated.

In recent years, hydrogel materials with suitable energy dissipation mechanisms and excellent mechanical properties have attracted much attention in tissue engineering due to their ability to mimic the natural cartilage structure. However, in cartilage tissue's regeneration and repair process, hydrogel materials should also possess satisfactory lubrication properties and biocompatibility. Therefore, preparing biocompatible low friction, high toughness hydrogels remain a challenge.

Chemodynamic therapy is an appealing modality in cancer treatment. However, its therapeutic effectiveness is impeded by insufficient catalytic efficiency and overexpression of glutathione (GSH) at the tumor site. In this study, a poly(-phenylenediamine) (PoPD)@copper sulfide (CuS) nanoplatform was developed as dual-level reactive oxygen species (ROS) amplifier for enhanced photothermal-chemodynamic therapy.

The aim of this study was to synthesize a quinoline-based MRI contrast agent, Gd-DOTA-FAPI04, and assess its capacity for targeting fibroblast activation protein (FAP)-positive tumors in vivo. Gd-DOTA-FAPI04 was synthesized by attaching a 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) complex of gadolinium(III) to FAP inhibitor FAPI04. The longitudinal relaxation time (T1) of the contrast agent was measured using a Siemens Prisma 3.

Against the traditional view, a recently published theory argued that isotope ratios are higher in convective precipitation but lower in stratiform precipitation and proposed that isotope ratios reflect rain type proportions. This theory has been widely cited despite some early reservations. Whether the theory represents a faithful reflection of signals of water isotope ratios remains unclear.
