Rare earth-doped upconversion nanomaterials are one of the luminescent materials that have received extensive attention in recent years and have important applications in fields such as biomedicine, optoelectronic devices, and security inspection. In this study, for NaYF:Yb,Er upconversion nanoparticles, the effects of experimental parameters such as reaction temperature, reaction time, and the content of surfactants on their crystal phase, size, and morphology were systematically investigated. By adjusting the experimental parameters, the size of the hexagonal phase upconversion nanoparticles can be effectively controlled within the range of 18-71 nm.

Neuroinflammation plays important roles in the pathogenesis and development of autism spectrum disorder (ASD). However, the mechanism by which peripheral organ inflammation affects neuroinflammation is still unclear. This study aimed to investigate that the interaction between the lungs and the brain as a potential mechanism underlying this effect.

Autologous tumor cells demonstrate considerable promise as individualized therapeutic vaccines owing to their endogenous neoantigen repertoire. Nevertheless, their suboptimal immunogenicity substantially impedes clinical translation. Herein, we engineered an innovative whole tumor cell vaccine platform utilizing photothermal CuSe nanoparticles, which encapsulate comprehensive tumor-associated antigens and intrinsic immunostimulatory molecules to elicit a polyvalent antitumor immune response.

As a chronic inflammatory illness of the respiratory system, asthma occurs due to various factors and is characterized by a T helper 2 (Th2)-skewed immune response, airway hyperresponsiveness, and reversible airflow obstruction. Toll-like receptors (TLRs) perform a "double-edged sword" function in asthma-related immunological dysregulation by recognizing damage-associated molecular patterns and pathogen-associated molecular patterns. In turn, the activation of some TLRs stimulates epithelial cells to release inflammatory cytokines, exacerbating Th2-driven inflammation and contributing to airway remodeling.

Epithelial-mesenchymal transition (EMT) is a key step in initiating tumor metastasis. Commonly, researchers focus on inhibiting EMT to prevent tumor metastasis. However, they ignore that tumor cells undergoing EMT are more vulnerable to disturbance from the external environment.

Toll-like receptors (TLRs) represent a critical class of protein molecules integral to nonspecific immunity (innate immunity), and serve as key mediators bridging between nonspecific and specific immune responses. As an important member of the TLR multigene family, toll-like receptor 4 (TLR4) holds particular significance due to its broad expression across various animal tissues and its pivotal roles in pathogen recognition, signal transduction, and the modulation of inflammatory responses. In aquaculture, Tlr4 has emerged as a promising target for the development of vaccines, immune enhancers, and adjuvants aimed at bolstering the health and disease resistance of aquatic animals, thereby reducing the reliance on antibiotics.

Achieving multiple antitumor efficacy in a single nanostructure is important for the development of photo-functional nanomedicines. In this paper, we report a direct triplet state energy converter (NCPRB) based on lanthanide nanocrystals, which can reduce the loss of near-infrared (NIR) light and improve the efficiency of generating reactive oxygen species (ROS) to induce ferroptosis through the process of direct energy transfer from rare earth ions (Nd) to the triplet state of the photosensitive molecule (chlorin e6, Ce6). Experimental results showed that the generated ROS combined with loaded resveratrol (RES) inhibited oxidative phosphorylation (OXPHOS) and electron transport chain (ETC) processes in the mitochondria of tumor cells and induced the onset of mitochondrial autophagy.

Early neurological deterioration is associated with poor functional outcomes in stroke patients, but the underlying mechanisms remain unclear. This study aims to understand the progression of stroke-related brain damage using a rhesus monkey model with ischemic occlusion. Multiparameter MRI was used to monitor the progressive evolution of the brain lesion following stroke.

Multi-angle polarization characteristics of water-leaving radiation are crucial for the retrieval of the oceanic constituents and the inherent optical properties (IOPs). However, the feasibility of using the polarization spectrum to retrieve the oceanic constituents and IOPs in global oceans remains unclear. In this study, global radiative transfer (RT) simulations for the Stokes vectors of water-leaving radiance () were performed, and a global polarization-based algorithm using the fully connected U-Net (FCUN) for retrieving the oceanic components and IOPs was developed.

Chronic psychosocial stress is associated with increased risk of psychiatric disorders. Magnetic resonance spectroscopy (MRS) in humans has been used to show that glutamate levels in medial prefrontal cortex (mPFC) following acute stress exposure adapt to recent chronic stress levels. Here, we sought to determine the presence of this glutamate stress response adaptation in rhesus macaques, whose societies are maintained by dominance relationships that are enforced by agonistic interactions and result in chronic stress phenotypes seen in humans.

As one of the key tools of biocatalysis, natural enzymes have received extensive attention due to their unique activity. However, the non-selective catalysis and early leakage induced by delivery dependency of natural enzymes can cause side effects on normal tissues. Moreover, although cuproptosis is an emerging tumor-inhibiting programmed cell death, the occurrence of cuproptosis leads to high expression of Cu-dependent lysyl oxidase-like 2 (LOXL2), which promotes tumor metastasis.

Hyperlipidemia has become a major global health challenge and one of the leading causes of mortality. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a circulating plasma protein, promotes the lysosomal degradation of hepatic low-density lipoprotein receptors (LDLR), thereby reducing the clearance of low-density lipoprotein (LDL) from blood plasma. PCSK9 has increasingly become a prominent therapeutic target for the development of lipid-lowering agents.
