Activation of endogenous tolerance to bleaching stress by high salinity in cloned endosymbiotic dinoflagellates from corals.

Background: Large-scale coral bleaching events have become increasingly frequent in recent years. This process occurs when corals are exposed to high temperatures and intense light stress, leading to an overproduction of reactive oxygen species (ROS) by their endosymbiotic dinoflagellates. The ROS buildup prompts corals to expel these symbiotic microalgae, resulting in the corals' discoloration.

Tumor-Repopulating Cell-Derived Microparticle-Based Therapeutics Amplify the Antitumor Effect through Synergistic Inhibition of Chemoresistance and Immune Evasion.

Traditional chemotherapy often encounters failure attributed to drug resistance mediated by tumor-repopulating cells (TRCs) and chemotherapy-triggered immune suppression. The effective inhibition of TRCs and the mitigation of drug-induced immune suppression are pivotal for the successful chemotherapy. Here, TRC-derived microparticles (3D-MPs), characterized by excellent tumor-targeting and high TRC uptake properties, are utilized to deliver metformin and the chemotherapeutic drug doxorubicin ((DOX+Met)@3D-MPs).

AMP-dependent protein kinase alpha 1 predicts cancer prognosis and immunotherapy response: from pan-cancer analysis to experimental validation.

Pancreatic cancer (PC) has poor prognosis. PRKAA1 (AMPK-α1) is the catalytic subunit of 5'-adenylate-activated protein kinase (AMPK), which plays a critical role in multiple stages of tumorigenesis and development. However, the biological mechanisms of PRKAA1 in the tumor microenvironment have not been well studied.

Simulation of Defoliation Effects on Relay Strip Intercropping Soybean: Elucidating Foliar Shedding and Leaf-to-Nodule Growth Plasticity.

Extensive foliar shedding in monoculture soybeans post-anthesis negatively impacts yield, whereas relay strip intercropping prolongs leaf area duration, enhancing productivity. However, little is known about the causes of leaf shedding in monoculture and its impact on physiological functions and plasticity of source and sink organs, we conducted a 4-year field experiment and leaf-removal simulations in relay intercropped soybeans. Results revealed that monoculture soybeans experienced severe self-shading and defoliation, while relay intercropping maintained better light conditions, supporting higher leaf area, nodule numbers, and carbon allocation.

In-situ nanoplatform with synergistic neutrophil intervention and chemotherapy to prevent postoperative tumor recurrence and metastasis.

In addition to residual tumor cells, surgery-induced inflammation significantly contributes to tumor recurrence and metastasis by recruiting polymorphonuclear neutrophils (PMNs) and promoting their involvement in tumor cell proliferation, invasion and immune evasion. Efficiently eliminating residual tumor cells while concurrently intervening in PMN function represents a promising approach for enhanced postoperative cancer treatment. Here, a chitosan/polyethylene oxide electrospun fibrous scaffold co-delivering celecoxib (CEL) and doxorubicin-loaded tumor cell-derived microparticles (DOX-MPs) is developed for postoperative in-situ treatment in breast cancer.

The modulation of temporal predictability on attentional boost effect.

Introduction: The attentional boost effect, characterized by better memory for background scenes coinciding with a detection target than a nontarget, is believed to stem from a temporary increase in attentional capacity at the time of an acute behavior-related event occurring. Sisk and Jiang's study found that the attentional boost effect also occurs when the target's appearance was predictable. Unfortunately, the duration of the predictive interval in Sisk and Jiang's study was fixed.

The storage mite Tyrophagus putrescentiae induces greater lung inflammation than house dust mites in mice.

Exposure to storage mite (SM) and house dust mite (HDM) allergens is a risk factor for sensitization and asthma development; however, the related immune responses and their pathology have not been fully investigated. The HDMs Dermatophagoides farinae and Dermatophagoides pteronyssinus and SM Tyrophagus putrescentiae are potent allergens that induce asthma. Most SM-related studies have focused on the allergic reactions of individuals by measuring their immunoglobulin (Ig)E expression.

Alterations in immunized antigens of Anisakis pegreffii by ampicillin-induced gut microbiome changes in mice.

The gut microbiome plays an essential role in host immune responses, including allergic reactions. However, commensal gut microbiota is extremely sensitive to antibiotics and excessive usage can cause microbial dysbiosis. Herein, we investigated how changes in the gut microbiome induced by ampicillin affected the production of IgG1 and IgG2a antibodies in mice subsequently exposed to Anisakis pegreffii antigens.

Intelligent drugs based on notch protein remodeling: a defensive targeting strategy for tumor therapy.

In the process of tumor treatment, systemic drug administration is hindered by biological barriers, leading to the retention of a large number of drug molecules in healthy tissues and causing unavoidable side effects. The precise deployment of drugs at the tumor site is expected to alleviate this phenomenon. Here, we take endostatin and Her2 (+) tumors as examples and develop an intelligent drug with simple "wisdom" by endowing mesenchymal stem cells (MSCs) with an intelligent response program (iMSC).
