In this paper, the concept of (λ, μ)-hesitant fuzzy subalgebras is introduced in Boolean algebra. Some properties of (λ, μ)-hesitant fuzzy subalgebras are discussed. Finally, we proved that the intersection and direct product of two (λ, μ)-hesitant fuzzy subalgebras are also (λ, μ)-hesitant fuzzy subalgebras in Boolean algebra.

In this paper, we introduce the notion of hesitant fuzzy( correlation) MP filters, some properties and equivalent conditions are investigated. The relationships between hesitant fuzzy MP filter and hesitant fuzzy correlation MP filter is disscussed. Finally, we prove the invariance between the image and the original image of hesitant fuzzy correlation filter is studied under the premise of homomorphism.

The re-emergence of Zika virus (ZIKV) in the Western Hemisphere has resulted in global public health crisis since 2015. ZIKV preferentially infects and targets human neural progenitor cells (hNPCs) and causes fetal microcephaly upon maternal infection. hNPCs not only play critical roles during fetal brain development, but also persist in adult brain throughout life. Yet the mechanism of innate antiviral immunity in hNPCs remains largely unknown. Here, we show that ZIKV infection triggers the abundant production of virus-derived small interfering RNAs in hNPCs, but not in the more differentiated progenies or somatic cells. Ablation of key RNAi machinery components significantly enhances ZIKV replication in hNPCs. Furthermore, enoxacin, a broad-spectrum antibiotic that is known as an RNAi enhancer, exerts potent anti-ZIKV activity in hNPCs and other RNAi-competent cells. Strikingly, enoxacin treatment completely prevents ZIKV infection and circumvents ZIKV-induced microcephalic phenotypes in brain organoid models that recapitulate human fetal brain development. Our findings highlight the physiological importance of RNAi-mediated antiviral immunity during the early stage of human brain development, uncovering a novel strategy to combat human congenital viral infections through enhancing RNAi.

Autophagy is induced in renal tubular cells during acute kidney injury; however, whether this is protective or injurious remains controversial. We address this question by pharmacologic and genetic blockade of autophagy using mouse models of cisplatin- and ischemia–reperfusion-induced acute kidney injury. Chloroquine, a pharmacological inhibitor of autophagy, blocked autophagic flux and enhanced acute kidney injury in both models. Rapamycin, however, activated autophagy and protected against cisplatin-induced acute kidney injury. We also established a renal proximal tubule–specific autophagy-related gene 7–knockout mouse model shown to be defective in both basal and cisplatin-induced autophagy in kidneys. Compared with wild-type littermates, these knockout mice were markedly more sensitive to cisplatin-induced acute kidney injury as indicated by renal functional loss, tissue damage, and apoptosis. Mechanistically, these knockout mice had heightened activation of p53 and c-Jun N terminal kinase, the signaling pathways contributing to cisplatin acute kidney injury. Proximal tubular cells isolated from the knockout mice were more sensitive to cisplatin-induced apoptosis than cells from wild-type mice. In addition, the knockout mice were more sensitive to renal ischemia–reperfusion injury than their wild-type littermates. Thus, our results establish a renoprotective role of tubular cell autophagy in acute kidney injury where it may interfere with cell killing mechanisms.

AimTo observe the therapeutic effect of low-dose amitriptyline (AMT) on epigastric pain syndrome (EPS) in patients with functional dyspepsia.MethodsSixty patients with EPS were randomly divided into the following two groups for a four-week clinical trial: routine treatment with pantoprazole (RT group) and the AMT group. The RT group was treated with 40 mg of pantoprazole once daily. The AMT group received 25 mg of AMT once daily before bedtime. The Nepean Dyspepsia Index (NDI) checklist, Hamilton Rating Scale of Anxiety/Depression (HAMA/HAMD), and Pittsburgh Sleep Quality Index (PSQI) were employed to evaluate dyspepsia symptoms, psychological distress, and sleep, respectively.ResultsAll items were similar between the two groups before treatment (0 week). After 4 weeks of treatment, the NDI–symptom checklist score as well as the severity and bothersomeness of EPS in the AMT group was significantly decreased compared with those in the RT group (p < 0.05). However, no differences were found in the frequency of NDI checklist, psychological status (HAMD/HAMA scores) of EPS, or sleep quality (PSQI score) between the two groups after treatment. In addition, the time to fall asleep was shorter in the AMT group compared with the RT group after 4 weeks of treatment (p < 0.05).ConclusionLow-dose AMT effectively improved the dyspepsia symptoms and the time to fall asleep in the EPS patients, compared with pantoprazole, although it did not reduce the psychological distress. Therefore, AMT could be considered as a good candidate for EPS treatment in the clinic.

Manual dish preparation for IVF in human fertility clinics or animal laboratories heavily relies on embryologists' experience, which can lead to occupational illness due to long-term and monotonous operation. Therefore, introducing an automated technique to replace traditional methods is crucial for improving working efficiency and reducing work burden for embryologists. In the current study in the mouse, both manual and automated methods were used to prepare IVF or embryo culture dishes. A one-way analysis of variance was conducted to compare several factors, including preparation time, qualified rates, media osmolality of dishes, fertilization rates, and embryonic development to assess the efficiency and potential of automated preparation. The results showed that automation system significantly reduced the required time and increased the efficiencies and qualified rates of dish preparation, especially for embryo culture dishes, without significantly altering medium osmolalities. There were no significant differences between two preparations in fertilization rates and embryo development in mice. Thus, automated dish preparation can improve working efficiency and qualified rates while maintaining fertilization rates and subsequent embryonic development without compromising osmolality stability of medium. It presents a superior alternative to manual preparation, reducing the workload of embryologists and facilitating the standardization of operational procedures.

This study aims to investigate the relationship between emotional labor and the impact of work–family conflict (WFC) on teachers’ intention to resign. A survey was conducted among 420 teachers from higher vocational colleges in 11 cities in Jiangsu Province, China. Reliability and validity tests, along with structural equation modeling, indicate that WFC positively affects teachers’ turnover intention. Moreover, emotional labor partially mediates the relationship between WFC and turnover intention. This study enriches the understanding of the relationship between WFC and turnover intention, highlights the mediating role of emotional labor, further expands the applicability of emotional labor theory, provides a theoretical basis for subsequent research and offers substantive teacher management suggestions for school managers. By reducing WFCs and optimizing teacher emotional management, the turnover rate of teachers can be reduced.

The emergence of tyrosine kinase inhibitors (TKIs) has changed the current treatment paradigm and achieved good results in recent decades. However, an increasing number of studies have indicated that the complex network of receptor tyrosine kinase (RTK) co-activation could influence the characteristic phenotypes of cancer and the tumor response to targeted treatments. One of strategies to blocking RTK co-activation is targeting the downstream factors of RTK, such as PI3K-AKT-mTOR pathway. RICTOR, a core component of mTORC2, acts as a key effector molecule of the PI3K-AKT pathway; its amplification is often associated with poor clinical outcomes and resistance to TKIs. Here, we discuss the biology of RICTOR in tumor and the prospects of targeting RICTOR as a complementary therapy to inhibit RTK co-activation.

With the global popularity of the concept of green and sustainable development, bamboo fiber technology has made great advances and found its way into several important materials applications. This study attempts to analyze the bamboo fiber technology from a patent perspective, hoping to help enterprises and R&D personnels better grasp the technology development trend and evolution path. Because the current patent analysis methods can not achieve the above objectives well, this paper proposes a new method of clustering and identifying sub-clusters by constructing bamboo fiber patent citation network and patent-international patent classification two mode network. Moreover, this paper uses natural language processing and main path analysis to perform subject word analysis and key technology identification on these technological sub-clusters, respectively. The analysis process and method in this study also have implications for patent analysis in technological fields such as graphene or carbon fiber.

Oxidative stress plays a critical role in postmenopausal osteoporosis, yet its impact on osteoblasts remains underexplored, limiting therapeutic advances. Our study identifies phospholipid peroxidation in osteoblasts as a key feature of postmenopausal osteoporosis. Estrogen regulates the transcription of glutathione peroxidase 4 (GPX4), an enzyme crucial for reducing phospholipid peroxides in osteoblasts. The deficiency of estrogen reduces GPX4 expression and increases phospholipid peroxidation in osteoblasts. Inhibition or knockout of GPX4 impairs osteoblastogenesis, while the elimination of phospholipid peroxides rescues bone formation and mitigates osteoporosis. Mechanistically, 4-hydroxynonenal, an end-product of phospholipid peroxidation, binds to integrin-linked kinase and triggers its protein degradation, disrupting RUNX2 signaling and inhibiting osteoblastogenesis. Importantly, we identified two natural allosteric activators of GPX4, 6- and 8-Gingerols, which promote osteoblastogenesis and demonstrate anti-osteoporotic effects. Our findings highlight the detrimental role of phospholipid peroxidation in osteoblastogenesis and underscore GPX4 as a promising therapeutic target for osteoporosis treatment. Oxidative stress contributes significantly to postmenopausal osteoporosis by impairing osteoblast function, but its precise mechanisms remain unclear. Here, the authors show that estrogen deficiency reduces GPX4 expression, leading to phospholipid peroxidation that impairs osteoblastogenesis, while GPX4 activators including 6- and 8-Gingerols can mitigate these effects.
