Summary: The study reveals the important role of surfactant protein D (SP-D) in regulating inflammation and immune response in osteoarthritis (OA). SP-D exhibits chondroprotective properties by downregulating inflammation-related genes, suppressing cytokine production, and reducing infiltration of inflammatory cells. The binding of SP-D to the TLR4/MD-2 complex further inhibits TLR4-mediated signaling activation. These findings suggest that SP-D has a beneficial effect in attenuating inflammation and preserving cartilage integrity in OA.

Summary: Nucleic-acid-sensing Toll-like receptors (TLRs) are synthesized in the endoplasmic reticulum and mature through specific processes in the endosomal compartment, where they are activated to initiate immune responses. In the endosomal compartment, DNA and RNA are degraded into ligands that activate corresponding TLRs, controlling immune responses in the endosomal compartment. NA-sensing TLRs and the endosomal compartment work together to monitor environmental cues and decide whether to launch innate immune responses.

Summary: Outbreaks of infectious disease in shrimp pose a serious threat to shrimp agriculture worldwide. Shrimp lack adaptive immunity and rely solely on innate immunity for defense against infectious disease. Toll-like receptors play a critical role in the shrimp innate immune system, with the identification of a new Toll-like receptor gene (MnToll) in Macrobrachium nipponense potentially involved in defense against WSSV.

Summary: Severely ill children in low- and middle-income countries experience high mortality rates from infectious diseases, and the risk of infection-related death is compounded by undernutrition. This study found that T cell function is impaired and innate immune responses are exaggerated in acutely ill children. Nutritional status is associated with the magnitude of cytokine responses. Further research is needed to understand the mechanisms of innate immune dysregulation in this population.

Summary: Toll-like receptors (TLRs) respond to pathogen constituents by recognizing and degrading nucleic acids with the help of nucleases. However, these nucleases also negatively regulate TLR responses by degrading ligands. Dysregulation of nucleic acid metabolism in endosomal compartments drives TLR-dependent pathologies in human diseases.

Summary: Chronic hepatitis B virus (HBV) infection is a significant global burden, and Toll-like receptors (TLRs) play a crucial role in immune response. However, HBV has developed strategies to inhibit TLR responses, limiting host immune response and promoting viral persistence. Recent studies indicate that stimulation of TLR signaling pathway enhances host immune response and suppresses HBV replication. These findings provide important insights for the use of TLR agonists as immunomodulators in the functional cure of HBV.

Summary: HyLine Hens are known for their excellent laying performance, while ZhenNing Hens are known for their unique flavor. The unique intestinal mucosa morphology in ZhenNing Hens is characterized by higher abundance of intestinal Lactobacillus, which contributes to increased villus wrinkles and improved intestinal absorption. Transplanting these Lactobacilli to HyLine Hens could potentially increase their intestinal probiotics abundance, adjust the intestinal stem cell function, promote epithelial proliferation, and increase villus winkles and mucosal absorption area.

Summary: This article addresses the stability and stabilization of almost periodic piecewise linear systems (APPLSs) with uncertain dwell time of subsystems. A novel mixed-mode time-varying Lyapunov function is constructed, considering the uncertainty in dwell time for the first time. A sufficient condition is proposed to guarantee the exponential stability of the system, where the switching instants over each period are unknown and inaccessible except their bounds. Additionally, a periodic time-scheduled state-feedback control approach is developed to stabilize the APPLS affected by dwell time uncertainty and possibly unstabilizable subsystem dynamics. The effectiveness of the proposed approach is demonstrated through a numerical example involving comparative case studies.

Summary: In this study, a new Argonaute protein called TsAgo was identified from Tepiditoga spiralis. TsAgo, similar to other reported proteins, prefers 5'OH-gRNA. It has been shown that TsAgo has DNA and RNA cleavage activity, can tolerate mismatches in certain regions of guides, and exhibits a stronger binding affinity for 5'OH-gRNA. Importantly, TsAgo can function as an RNA-guided programmable nuclease to cut plasmid DNA at high temperatures.

Summary: In this study, we propose a domain adaptive graph infomax method that computes node representations through neighborhood aggregation and maximizes mutual information between node representations and global summaries to encode global structural information. Conditional adversarial networks are used to reduce the domain discrepancy by aligning the multimodal distributions of node representations. Experimental results on real-world datasets validate the performance of our method in comparison with state-of-the-art baselines.

Summary: The high cost of data labeling results in node label shortage. To address this, a graph-based semi-supervised learning method is proposed, which leverages unlabeled nodes to train together with scarce labeled nodes. An attention-based aggregator is designed to generate node representations by aggregating information from neighboring nodes, and adversarial training is employed to improve robustness and generalization.

Summary: This study compared pregnancy outcomes of patients with gestational transient thyrotoxicosis (GTT) and Graves' disease (GD) in the first trimester. The results showed that the incidence of gestational diabetes mellitus (GDM) was higher in the GTT group compared to the normal thyroid function (NTF) group. The untreated and treated GD groups had a higher risk of premature delivery, gestational hypertension, and miscarriage compared to the NTF group. Early diagnosis of GTT and GD, as well as appropriate treatment for GD, may improve pregnancy outcomes.

Summary: We examine the impact of uncertainty of uncertainty (UOU) on corporate accounting conservatism and find a positive association. Mechanism analysis reveals that under UOU, creditors' demand for real information drives an increase in accounting conservatism. Further analysis shows that the effect of UOU is more pronounced in non-SOEs and firms with weak external monitoring mechanisms. Our study highlights the significant role of contract demand in corporate governance under uncertainty about levels of uncertainty.
