Abstract
The permeability of the blood-brain barrier (BBB) is increased in Alzheimer's disease (AD). This plays a key role in the instigation and maintenance of chronic inflammation during AD. Experiments using AD models showed that the increased permeability of the BBB was mainly caused by the decreased expression of tight junction-related proteins occludin and claudin-5. In this study, we found that ZNF787 and HDAC1 were upregulated in β-amyloid (Aβ)1-42-incubated endothelial cells, resulting in increased BBB permeability. Conversely, the silencing of ZNF787 and HDAC1 by RNAi led to reduced BBB permeability. The silencing of ZNF787 and HDAC1 enhanced the expression of occludin and claudin-5. Mechanistically, ZNF787 binds to promoter regions for occludin and claudin-5 and functions as a transcriptional regulator. Furthermore, we demonstrate that ZNF787 interacts with HDAC1, and this resulted in the downregulation of the expression of genes encoding tight junction-related proteins to increase in BBB permeability. Taken together, our study identifies critical roles for the interaction between ZNF787 and HDAC1 in regulating BBB permeability and the pathogenesis of AD.

Abstract
Three-dimensional (3D) printing technology with enhanced fidelity can achieve multiple functionalities and boost electrochemical performance of customizable planar micro-supercapacitors (MSCs), however, precise structural control of additive-free graphene-based macro-assembly electrode for monolithic integrated MSCs (MIMSCs) remains challenging. Here, the large-scale 3D printing fabrication of customizable planar MIMSCs is reported utilizing additive-free, high-quality electrochemically exfoliated graphene inks, which is not required the conventional cryogenic assistance during the printing process and any post-processing reduction. The resulting MSCs reveal an extremely small engineering footprint of 0.025 cm2 , exceptionally high areal capacitance of 4900 mF cm-2 , volumetric capacitance of 195.6 F cm-3 , areal energy density of 2.1 mWh cm-2 , and unprecedented volumetric energy density of 23 mWh cm-3 for a single cell, surpassing most previously reported 3D printed MSCs. The 3D printed MIMSC pack is further demonstrated, with the maximum areal cell count density of 16 cell cm-2 , the highest output voltage of 192.5 V and the largest output voltage per unit area of 56 V cm-2 up to date are achieved. This work presents an innovative solution for processing high-performance additive-free graphene ink and realizing the large-scale production of 3D printed MIMSCs for planar energy storage.

Abstract
Sepsis is defined as "a life-threatening organ dysfunction caused by a dysregulated host response to infection". Although the treatment of sepsis has evolved rapidly in the last few years, the morbidity and mortality of sepsis in clinical treatment are still climbing. Sirtuins (SIRTs) are a highly conserved family of histone deacetylation involved in energy metabolism. There are many mechanisms of sepsis-induced myocardial damage, and more and more evidence show that SIRTs play a vital role in the occurrence and development of sepsis-induced myocardial damage, including the regulation of sepsis inflammation, oxidative stress and metabolic signals. This review describes our understanding of the molecular mechanisms and pathophysiology of sepsis-induced myocardial damage, with a focus on disrupted SIRTs regulation. In addition, this review also describes the research status of related therapeutic drugs, so as to provide reference for the treatment of sepsis.

Abstract
Fermentation is considered an effective tool for improving the functional characteristics of food. In this study, Lacticaseibacillus casei YQ336 was used to ferment yellow whey, and physical and chemical analysis was performed to identify the changes in the nutritional components and antioxidant activity of the fermented yellow whey. Non-targeted metabolomics was used to study the transformation of small molecular substances in the fermented yellow whey. After 48 h of pure culture fermentation with L. casei YQ336, the pH of yellow whey decreased significantly (p < 0.05). Meanwhile, the content of total acids, organic acids, sugars, total phenols, and total flavonoids and the antioxidant activity showed a significant increase (p < 0.05). A total of 628 differential metabolites were identified between fermented and unfermented yellow whey samples, of which 293 were upregulated and 335 were downregulated. After fermentation, due to the growth and metabolic activity of L. casei YQ336, meaningful metabolites such as homovanillic acid, lactic acid, oxalic acid, L-glutamic acid, and phenylalanine, as well as phenyllactic acid, gallic acid, and genistein were produced. This increased the organic acid content and antioxidant activity of yellow whey. The findings provide a theoretical and practical basis for further research on the bio-functional activity of yellow whey and the recycling and utilization of food by-products.

Abstract
We have previously shown that Liang-Yan-Yi-Zhen-San (LYYZS), an ancient Chinese herbal formula, can promote the browning of white adipose tissue. In this study, we sought to determine which active ingredients of LYYZS mediated its effects on the browning of white adipose tissue. Employing ultra-high performance liquid chromatography-Q-Exactive HF mass spectrometry, a total of 52 LYYZS ingredients were identified. On this basis, 1,560 ingredient-related targets of LYYZS were screened using the HERB databases. Meanwhile, RNA sequencing analysis of the inguinal white adipose tissue of mice produced a total of 3148 genes that were significantly differentially expressed following LYYZS treatment and differentially expressed genes regarded as browning-related targets. Through the network pharmacological analysis, a total of 136 intersection targets were obtained and an ingredient-target-pathway network was established. According to network pharmacology analysis, 10 ingredients containing trans-cinnamaldehyde, genistein, daidzein, calycosin, arginine, coumarin, oleic acid, isoleucine, palmitic acid and tyrosine were regarded as active ingredients of browning of white adipose tissue. Integrated evaluation using chemical analysis, transcriptomics and network pharmacology provides an efficient strategy for discovering the active ingredients involved in how LYYZS promotes the browning of white adipose tissue.

Abstract
AIMS The present study aimed to explore the effects of a guided self-help mindfulness intervention on psychological resilience and job burnout among psychiatric nurses. BACKGROUND Psychiatric nurses work in challenging and potentially high stress settings. Mindfulness interventions can improve psychological resilience and reduce job burnout of nurses. However, face-to-face delivery of mindfulness interventions may be inconvenient for individuals. Guided self-help interventions may be more accessible. METHODS This randomized controlled trial was conducted from January to August 2022. One hundred and eighteen psychiatric nurses were randomized into the intervention and control groups. The individuals in the intervention group received an 8-week guided self-help mindfulness intervention, while the individuals in the control group received a psycho-educational brochure. The Five Facet Mindfulness Questionnaire, the Connor-Davidson Resilience Scale and the Maslach Burnout Inventory-Human Services Survey were used to evaluate the levels of mindfulness, psychological resilience and job burnout, respectively. RESULTS After an 8-week intervention, compared with the control group, the levels of mindfulness and psychological resilience were higher, while the level of job burnout was lower in the intervention group. CONCLUSIONS The guided self-help mindfulness intervention can improve psychological resilience and reduce job burnout among psychiatric nurses.

Abstract
Polyphagous insects could affect agricultural production, which leads to serious economic losses. Due to the negative effects of synthesized insecticides, finding eco-friendly and new biopesticides is emergent. To develop natural origin insecticides, an integrative approach combining antifeedant activity screening, genome mining, and molecular networking has been applied to discover antifeedant secondary metabolites from Streptomyces sp. NA13, which leads to the isolation of a novel antimycin Q (1) and six known antimycin analogs (antimycins A1a, A2a, A3a, A4a, A7a, and N-formylantimycic acid methyl ester, 2-7). Their structures were identified by high-resolution mass spectrometry (HR-MS) and nuclear magnetic resonance (NMR) spectroscopic. The absolute configuration of 1 was elucidated by the comparison of coupling constant, electronic circular dichroism (ECD) analysis, and NMR calculations. 1-6 exhibited different levels of antifeedant activities against Helicoverpa armigera, especially 1-4. At the same time, the antifeedant activity of antimycin was reported firstly.
