The progression and metastasis of pancreatic ductal adenocarcinoma (PDAC) is highly dependent on the tumour microenvironment. Most tumour-associated macrophages (TAMs) are M2 phenotype macrophages, which normally show anti-inflammatory functions in numerous disorders. Previously, we found that alternatively activated showed pro-inflammatory characteristics upon stimulation with hepatoma cell-derived debris; however, molecular mechanism was unclear.In vitro vivo experiments were employed to...

Abstract The amygdala, one of the most studied brain structures, integrates brain-wide heterogeneous inputs and governs multidimensional outputs to control diverse behaviors central survival, yet how amygdalar input-output neuronal circuits are organized remains unclear. Using a simplified cell-type- projection-specific retrograde transsynaptic tracing technique, we scrutinized afferent four major output groups in basolateral complex (BLA) that project bed nucleus stria terminals (BNST),...

Early life stress is thought to be a risk factor for emotional disorders, particularly depression and anxiety. Although the excitation/inhibition (E/I) imbalance has been implicated in neuropsychiatric whether early affects E/I balance medial prefrontal cortex at various developmental stages unclear. In this study, rats exposed maternal separation (MS) that exhibited well-established paradigm were used evaluate adolescence (postnatal day P43-60) adulthood (P82-100) by behavior tests,...

Recently, applying computational models developed in cognitive science to psychiatric disorders has been recognized as an essential approach for understanding mechanisms underlying symptoms. Autism spectrum disorder is a neurodevelopmental that hypothesized affect information processes the brain involving estimation of sensory precision (uncertainty), but mechanism by which observed symptoms are generated from such abnormalities not thoroughly investigated. Using humanoid robot controlled...

FOLFIRINOX (FFX) or abraxane plus gemcitabine (AG)-based chemotherapy is used widely as firstline treatment for patients with pancreatic cancer. However, their use in the elderly discouraged because of adverse events. More clinical data about therapeutic response and tolerability to FFX AG patents (over 70 years old) are required.Patients advanced cancer (n = 203; 131 metastatic (MPC) 72 locally (LAPC)) were treated using modified-FFX (mFFX) mFFX sequentially. The grouped according age,...

ABSTRACT Introduction Standard treatments provide limited benefits for patients with intermediate‐ or advanced‐stage hepatocellular carcinoma (HCC). This retrospective observational study aimed to assess the potential improvements in outcomes associated systemic therapies receiving transarterial chemoembolization (TACE) initially unresectable HCC. Methods Between February 2019 and March 2023, we reviewed diagnosed intermediate‐to‐advanced HCC who were treated either TACE combined...

Context: Immune checkpoint blockades (ICBs) have been approved widely to treat various malignancies. Autoimmune diabetes mellitus, which can be caused by programmed cell death protein 1 (PD-1) inhibitors, is rare. Sintilimab, a monoclonal anti-PD-1 antibody, has in China for the treatment of Hodgkin's lymphoma and was used our clinical trial patients with unresectable hepatocellular carcinoma (HCC). Case Presentation: We present first case autoimmune during Sintilimab patient HCC,...

However, prognosis still remains poor, novel options are urgently need. Sintilimab, a human IgG4 monoclonal antibody that binds to programmed cell death receptor-1(PD-1), has shown remarkable efficacy in various cancers. We designed CISPD3-trial China, aimed determine and safety combination Sintilimab mFFX recurrent PDAC. Methods: In this single center,...

The pathogenesis of autism spectrum disorder (ASD) is not well understood, especially in terms immunity and inflammation, there are currently no early diagnostic or treatment methods. In this study, we obtained six existing Gene Expression Omnibus transcriptome datasets from the blood ASD patients. We performed functional enrichment analysis, PPI CIBERSORT algorithm, Spearman correlation with a focus on expression profiling hub genes immune cells. validated that monocytes nonclassical were...

This study demonstrates that the prediction error minimization (PEM) mechanism can account for emergence of reciprocal interaction between two cognitive agents. During interactive processes, alternation forming and deforming interactions may be triggered by various internal external causes. We focus in particular on causes derived from a dynamic uncertain environment. Two small humanoid robots controlled an identical neural network model using PEM were trained to achieve set coherent...
