Sistem Informasi Pembelajaran Taman Pendidikan Al-Qur’an di Yayasan Al-Muttaqien Jadid (TPQ)

This research aims to determine the TPA academic system currently running at Al-Muttaqien Jadid. This research is descriptive research using qualitative methods. Data collection was carried out by interviews, observation and documentation, as well as using literature studies from various sources related to the questions asked in the research. It was found that there was a problem with the TPA Academic system, including regarding student registration, class division and scheduling, which still uses the bookkeeping method, it is difficult to get information regarding student data, class data, teacher data and subject data. Apart from that, the process of class division and scheduling cannot be completed quickly due to difficulties in finding data, the number of students being placed in excess of the quota often occurs, so mistakes or mistakes often occur in recording students' grades. So that registration, payment and distribution data can be processed quickly and accurately, a web-based application is needed. By implementing this application, it can help academic processing in preparing payment reports and student registration so that the management of TKA-TPA in the data collection process makes coordination and coaching easier. From the research results, it can be concluded that registration, payment, class division and scheduling using the bookkeeping method requires quite a long time in processing data and storing data.

Early-Life Exposures and Social Stratification

Adverse environmental exposures—war and violence, natural disasters, escalating heat, worsening air quality—experienced in pregnancy are consequential for multiple domains of well-being over the life course, including health, cognitive development, schooling, and earnings. Though these environmental exposures become embodied via biological processes, they are fundamentally sociological phenomena: Their emergence, allocation, and impact are structured by institutions and power. As a result, consequential early-life environmental exposures are a critical part of the sociological understanding of social stratification, intergenerational mobility, and individual and cohort life course trajectories. We review theory and evidence on prenatal exposures, describe enduring methodological issues and potential solutions for elucidating these effects, and discuss the importance of this evidence for the stratification of opportunity and outcomes in contemporary societies.

The Cartojuridism of the British East India Company

Abstract This paper will engage with the early colonial maps of the British East India Company to analyze its representative, as well as creative, functions, delineating how maps represent existing legal relations, entrench hierarchies, and visually transmit projected, and aspired, notions of legal authority and sovereignty. This paper studies the constitutive role of cartography apropos law, territory, and social order, in a specific historical context, by examining the crucial political role played by the British East India Company's cartographic practices and maps in aspiring and imagining the transplantation and establishment of English sovereignty in the Indian subcontinent. This paper will also show how British maps visually entrenched and supplemented unique forms of social hierarchy and marginalization, and legal categories and stratifications, in Indian cities. By analyzing maps, memoirs, cartouches, dedications, ornaments, plans, prospects, and historical manuscripts appertaining to the eighteenth and early nineteenth century operations of the Company, this paper will demonstrate, firstly, that cartography preceded, visually imagined, and set the stage for the coalescence of British sovereignty and the expansion of its law in the Indian subcontinent; secondly, that cartography provided the visual support for social ordering; and thirdly, that maps do not have a singular function. This paper proposes a notion of cartojuridism to capture the myriad ways in which cartography, law, sovereignty, and society intersect and relate with each other.

Using Improved Hybrid Grey Wolf Algorithm Based on Artificial Bee Colony Algorithm Onlooker and Scout Bee Operators for Solving Optimization Problems

Grey Wolf optimization (GWO) is a newly developed stochastic meta-heuristic technique motivated by nature. It shows potential in diverse optimization challenges. It replicates grey wolf hunting behaviour and social hierarchy, exploring the solution space similar to their natural process. The algorithm efficiently explores and converges to the optimal solution. However, a drawback of the standard GWO is its limited exploitation capability due to its exploration-focused iterations. This may hinder finding the optimal solution nearby, leading to lower local convergence rates and degraded solution quality. To address this, the GWO-Employed-Onlooker model suggests incorporating the onlooker and scout bee operators from the artificial bee colony algorithm (ABC) during the position-changing stage of the grey wolves. This enhances exploitation capability, resulting in improved local convergence rates and better solution quality. The proposed method’s performance is evaluated on various optimization functions and compared their convergence rate to standard GWO, Genetic Algorithm (GA), Firefly Algorithm (FA), ABC, and Ant Colony Optimization (ACO) techniques. The results demonstrate that the proposed strategy GWO-Employed-Onlooker is better, indicating that it is valuable in solving optimization problems.

AI Within Online Discussions: Rational, Civil, Privileged?

While early optimists have seen online discussions as potential spaces for deliberation, the reality of many online spaces is characterized by incivility and irrationality. Increasingly, AI tools are considered as a solution to foster deliberative discourse. Against the backdrop of previous research, we show that AI tools for online discussions heavily focus on the deliberative norms of rationality and civility. In the operationalization of those norms for AI tools, the complex deliberative dimensions are simplified, and the focus lies on the detection of argumentative structures in argument mining or verbal markers of supposedly uncivil comments. If the fairness of such tools is considered, the focus lies on data bias and an input–output frame of the problem. We argue that looking beyond bias and analyzing such applications through a sociotechnical frame reveals how they interact with social hierarchies and inequalities, reproducing patterns of exclusion. The current focus on verbal markers of incivility and argument mining risks excluding minority voices and privileges those who have more access to education. Finally, we present a normative argument why examining AI tools for online discourses through a sociotechnical frame is ethically preferable, as ignoring the predicable negative effects we describe would present a form of objectionable indifference.

Poor air quality at school and educational inequality by family socioeconomic status in Italy

This paper investigates social stratification in the context of poor air quality's impact on educational achievement in Italy, a country characterized by high levels of air pollution and significant geographical diversity. We address two primary questions: firstly, whether students from different socio-economic backgrounds vary in their exposure to high levels of particulate matter (PM2.5) at school, and secondly, if the effect of exposure to poor air quality on academic performance differs between children from high and low socio-economic status families. Utilizing a novel dataset comprising test scores in math and reading for 456,508 8th-grade students, collected nationally in Italy in 2019, we geocode the locations of 6882 schools based on their addresses and link the level of air pollution in the surrounding areas using PM2.5 data from the Atmospheric Composition Analysis Group. To address potential confounding factors, we estimate municipality and province fixed effects and control for indicators of school neighborhood characteristics and school quality. Our analysis yields three key findings. Firstly, students from higher socio-economic backgrounds tend to attend schools with higher PM2.5 levels. However, the positive association between SES and exposure to PM2.5 disappears when adding province and municipality fixed effects, suggesting that the positive association can be explained by selection into provinces and municipalities by SES. Secondly, we identify a small yet consistent negative effect of PM2.5 on math and reading test scores. Thirdly, this adverse impact is primarily observed among students from low socio-economic backgrounds. We conclude that the relationship between environmental risks and disparities in educational achievement based on social background in Italy is nuanced and critically influenced by the country's specific context.

Rank, stress, and risk: A conjecture

A perception at the core of studies that consider the link between social rank and stress (typically measured by the so-called stress hormone cortisol) is that the link is direct. Examples of such studies are Bartolomucci (2007), Beery and Kaufer (2015), and Koolhaas et al. (2017). A recent and stark representation of this body of work is a study by Smith-Osborne et al. (2023), who state that “social hierarchies directly influence stress status” (Smith-Osborne et al. p. 1537, italics added). In the present paper, we reflect on this “direct” perspective. We conjecture that the link between social rank and stress involves an intervening variable: an indirect relationship arises when the loss of rank triggers a behavioral response in the form of risk taking aimed at regaining rank, and it is the engagement in risk-taking behavior that is the cause of an elevated level of cortisol. Smith-Osborne et al., as well as others whose papers are cited by Smith-Osborne et al. and who, like Creel (2001) and Avitsur et al. (2006), conducted comprehensive research on the association between rank (social standing) and stress, do not refer to risk taking at all. We present four strands of research that lend support to our conjecture: evidence that in response to losing rank, individuals are stressed; evidence that in response to losing rank, individuals resort to risk-taking behavior aimed at regaining their lost rank; evidence that there exists a link between engagement in risky activities or exposure to risk and elevated levels of cortisol; and an analytical perspective on incidence and intensity, namely a perspective that shows how the willingness to take risks responds to a change in rank, specifically, how a loss of rank triggers a greater willingness to take risks and how this trigger is stronger for individuals whose rank is higher.

Racist dogs and classist rats?

In cities across the world, animals reflect, reproduce and transform urban inequalities – yet their role in mediating social hierarchies remains undertheorized. Urban scholars have begun to highlight the importance of infrastructures and technologies in configuring access to essential goods and services. While this research provides key insights into how non-human entities mediate unequal relations, it has largely overlooked how certain animals – „political animals“ – also co-produce inequalities. This article focuses on two critical urban domains, security and public health, that are often characterized by stark inequalities, and takes the role of key animals within these domains – dogs and rats, respectively – as a new analytical entry-point. Security dogs are socialized to identify threatening individuals on the basis of classed and raced markers. Rats thrive in upscale neighborhoods with historical architecture and abundant green space – yet the public health risks and the stigma associated with these rodents may disproportionately affect low-income residents. Drawing on research on security dogs in Kingston, Jamaica and rats in Amsterdam, this talk discusses the role of animals in the formation of sociospatial boundaries, and the distribution of resources and risks across urban spaces and populations. Focusing on the interactions these two types of „political animals“ have with both humans and infrastructure, it sets out a research agenda for studying how animals’ everyday encounters with their cultural and material environments combine to result in (in-)equitable social outcomes.

Simultaneous Politicization of Identities to Increase Candidates' Electability: A Case Study of the 2020 Regional Head Election of East Sumba Regency

Identity politicization became popular in areas of Indonesia after the 1998 reform. Political candidates use this practice to increase electability and acquire power in electoral political contestation. This condition also occurred at the 2020 Regional Head Election (Pilkada) in the East Sumba Regency. The study aims to investigate identity politicization in various forms and its impact on the 2020 Pilkada in the East Sumba Regency. This research used a qualitative method with a case study approach. The findings indicate politicized identities during the Pilkada, including candidates' religious and ethnic identities, areas of origin, social stratification, and government bureaucracy. An interesting finding in this study is the politicization of the various identities existing in society and was carried out simultaneously to gain voter support to increase the candidates' electability. The academic contribution of this research is to exploit the full potential of identity simultaneously, including kabihu identity, to respond to the candidates' practical political interests to gain power despite the impact on segregation and polarization in society and diluting Sumba cultural values. Furthermore, this study advises the government on how to improve the quality of future Pilkada.

Customary ‘child selling’ and the ‘untouched mother’ in Western Odisha, India: understanding the legitimatization of caste hierarchy

AbstractThe place of mothers is respected in all societies irrespective of their social, cultural, and geographical differences. The mother‐child relationship is considered one of the most sacred in the world. This article explores the age‐old customary ‘child selling’ prevalent in Western Odisha, a voluntary and non‐remunerative practice of childcare during infancy to save children from illness and Yama, the Hindu god of death, where the ‘caring mother’ belongs to the bottom of the social hierarchy, mainly from the (ex‐)untouchable castes. According to popular belief, Yama does not visit the untouchables because of their ‘filthy’ environment and their gods. Hence, it is considered a safer place for children, especially weak ones or those with the chronic illnesses of the upper castes, to conceal themselves from the evil eyes of Yama. The epistemology of this article aims to explore the hegemonic nature of the caste systems, which overwhelms the revered mother‐child relationship. Further, it tries to understand the (re)production of caste and legitimization of sociopsychological conditions for the marginalization and backwardness of ‘caring mothers’. Despite the sacred and intimate relationship between the ‘caring mother’ and child, the institution of ‘ritual selling’ reproduces caste inequalities, and again the former becomes an ‘untouchable’.

A novel intrusion detection system based on a hybrid quantum support vector machine and improved Grey Wolf optimizer

AbstractThe Internet of Things (IoT) has grown significantly in recent years, allowing devices with sensors to share data via the internet. Despite the growing popularity of IoT devices, they remain vulnerable to cyber-attacks. To address this issue, researchers have proposed the Hybrid Intrusion Detection System (HIDS) as a way to enhance the security of IoT. This paper presents a novel intrusion detection model, namely QSVM-IGWO, for improving the detection capabilities and reducing false positive alarms of HIDS. This model aims to improve the performance of the Quantum Support Vector Machine (QSVM) by incorporating parameters from the Improved Grey Wolf Optimizer (IGWO) algorithm. IGWO is introduced under the hypothesis that the social hierarchy observed in grey wolves enhances the searching procedure and overcomes the limitations of GWO. In addition, the QSVM model is employed for binary classification by selecting the kernel function to obtain an optimal solution. Experimental results show promising performance of QSVM-IGWO in terms of accuracy, Recall, Precision, F1 score, and ROC curve, when compared with recent detection models.

Social hierarchy differentially influences the anxiety-like behaviors and dendritic spine density in prefrontal cortex and limbic areas in male rats

Social hierarchy is a fundamental feature of social organization that can influence brain and emotional processing regarding social ranks. Several areas, including the medial prefrontal cortex (mPFC), the hippocampus, and the basolateral nucleus of the amygdala (BLA), are recognized to be involved in the regulation of emotional processing. However, its delicate structural correlates in brain regions are poorly understood. To address this issue, social hierarchy in home-caged sibling Wistar rats (three male rats/cage) was determined by employing a social confrontation tube test (postnatal weeks 9-12). Then, locomotor activity and anxiety-like behaviors were evaluated using an open-field test (OFT) and elevated plus-maze (EPM) at 13 weeks of age. The rapid Golgi impregnation method was conducted to quantify the spine density of the first secondary branch of the primary dendrite in 20µm length. The results indicated that dominant rats had significantly higher anxiety-like behaviors compared to subordinates, as was evident by lower open-arm entries and time spent in the EPM and lower entries and time spent in the center of OFT. The spine density analysis revealed a significantly higher number of spines in subordinates compared to the dominant rats in dmPFC pyramidal neurons and the apical and basal dendrites of hippocampal CA1 pyramidal neurons. However, the spine density of pyramidal-like neurons in the BLA was higher in dominant rats. Our findings suggest that dominant social rank is associated with higher anxiety and differential density of the dendritic spine in the prefrontal cortex and limbic regions of the brain in male rats.

Modern Utopia: Yuval Noah Harari

The article is devoted to the analysis of the current state of utopia, in particular, attention is paid to the problem of the crisis of utopian thought that arose at the end of the twentieth century and continues to the present. The author examines the features of philosophical criticism of modernity by the ideologist of the future and futurist Yuval Noah Harari. The purpose of this study is to find out whether Yuval Noah Harari is a utopian of our time, and the model of the near future proposed by Y. Harari, which represents a natural reaction of society to the global value and ideological crisis, is a modern utopia by signs. In the course of researching issues related to the crisis of utopian thought of our time, the author proceeds from the postulate that utopia is a special type of predictive reflection, a worldview built in orientation towards the probable future. The research is based on the concept of K. Manheim, according to which utopia is an attitude of consciousness oriented towards the future, as well as from the definition of utopia as an idealized social construct, fundamentally unrealizable as a whole. The scientific novelty of this study is as follows: the main concepts of understanding modern utopia are identified, the specifics of describing the realities of modernity are substantiated, characteristics relevant to the worldview of the XXI century are identified, proceeding from the categories of philosophizing of a new kind, the features of Yuval Noah Harari's criticism of the utopia of a new formation are revealed. The result of the study shows that Yuval Noah Harari is a modern utopian, and his project is considered an escapist-type utopia of modernity, based on social stratification. This utopia is escapist, because for one part of humanity it is unrealizable and is only a means of escape from reality, while for another part of it it can serve as a full-fledged project of the future, claiming to be realized. It also has such an ontological property as temporality, since it corresponds to the realities of its time in terms of content.

Social rank affects the endocrine response to frequent regroupings in grazing dairy heifers

The objectives of this study were to determine the social behavior response to repeated social regrouping (SR), and if social rank and the changes of social rank affect the growth rate and some metabolites and hormones linked to energy status, in “resident” replacement dairy heifers subjected to SR for 205 d. Fourteen dairy heifers (153.3 ± 16.1 kg; 9 to 11 mo-old), maintained under grazing conditions, were regrouped every 21 d with 5 new animals (total = 10 SR). Two days after each SR, heifers were weighed and their withers heigh was measured, average daily gains for each period was calculated, and blood samples for nonesterified fatty acids, glucose and insulin-like growth factor type 1 (IGF-1) were taken. Concentrations of NEFA and glucose were determined in every SR, while IGF-1 concentrations were determined only at SR 1, 3, 4, 7, and 9. Social behavior was registered by continuous sampling 2 d before SR, the day of SR, and 7 d later. Social status was calculated by the ETlog software, considering the total number of agonistic interactions on 2 d before and 7 d after each SR. A dominance scale was constructed in each SR, and heifers were categorized as high-ranked heifers (HRA), medium-ranked heifers (MRA), and low-ranked heifers (LRA). In addition, the social rank in the first and the last 5 SRs were compared, resulting in 3 categories: heifers that remained in the same social rank (Mai), and heifers that lowered (Low) and raised (Rai) their social ranks. Variables were analyzed by repeated measures using a generalized lineal mixed model, considering the social rank in each SR or the change in social rank, the number of SR and their interaction as main effects, and the farm of origin and animal as random effects. Heifers performed more agonistic (2.6 vs 1.8 ± 0.6, day of SR and 7 d later, respectively) and total (3.8 ± 1.2 vs 2.5 ± 0.7, day of SR and 7 d later, respectively) interactions on the day of each SR than 7 d after, while the number of interactions decreased after the first 2 SRs. Medium-ranked heifers presented greater IGF-1 concentrations than HRA-ranked heifers at SR1, SR4, and SR9, and than LRA heifers at SR3 and SR4, while IGF concentrations were greater in HRA heifers than MRA- heifers at SR3 and SR7. In addition, LRA heifers had greater IGF-1 concentrations than MRA ones at SR3 and compared with HRA heifers at SR9. Heifers that lowered their social had greater IGF-1 concentrations than Mai heifers along the SR (132.5 ± 17.1 vs 97.8 ± 11.2 ng/mL, Low and Mai heifers, respectively) and at SR1, SR3, and SR9. In conclusion, although regrouping animals according to their characteristics can facilitate farm handling, it should be considered that endocrine profile may be affected according to heifers' position in the social hierarchy.

Revisiting Aristotle’s Master-Slave Relationship: A Casual Evaluation in the Context of Human-AI Dynamics

This paper sought to explore Aristotle's handling of the notion of natural slavery and its relevance in ongoing discussions concerning the ethics of artificial intelligence. Using an extensive literature review covering his discussions on slavery in the Politics and the Nicomachean Ethics, this study delved into the philosophical underpinnings of slavery within Aristotle's political theory and examines its ramifications within the domain of ethical technology. Consequently, while Aristotle's theory of natural slavery suggests that certain individuals are predisposed to service due to deficiencies in rational capacity, this concept was analysed in the context of modern AI technology, raising ethical concerns about autonomy, control and social hierarchy in human AI interactions. By relating Aristotle's philosophical framework to contemporary AI ethics, this study offered an understanding of the ethical implications of advancing technology and encouraged interdisciplinary dialogue between philosophy, ethics and AI research.

Sexual violence against children and adolescents in Paraná State: geospatial analysis and main socioeconomic indicators

ObjectiveChild sexual violence is a multidimensional problem of many contemporary societies, affecting people of all sexes, social stratum and age groups. Offenses involving children and adolescents are more serious, given their total or partial dependence on parents and caregivers. Information on child sexual violence in Brazil is found in raw form and without detail. The objective was to compare the information with social and economic data in the state of Paraná. MethodsThe authors conducted a retrospective study of secondary data from the Notifiable Diseases Information System (SINAN) on cases of sexual violence involving victims aged 0 to 19 years. Results are presented according to notification characteristics. The authors applied exploratory spatial data analysis to assess spatial autocorrelations and investigated relationships by the ordinary least squares regression model. ResultsBetween 2017 and 2021, there were 13,403 reports of child sexual violence in Paraná State, Brazil. Most victims (82.8%) were female and aged between 10 and 14 years. The majority of sexual violence cases (67.8%) occurred in the home environment. The highest rates on a population basis were observed in the North Central and Greater Curitiba regions, mainly in cities with higher population density and with higher rates of other types of violence. ConclusionThe results provide data that can promote a broader understanding of the distribution of sexual violence and the state and associated variations. It is expected to improve the provision of care for victims of child sexual violence and assist in strategic planning to prevent future offenses.

Increased cardiovascular risks and mortality in prurigo nodularis: a global cohort study

BackgroundPrurigo nodularis (PN) presents with intensely itchy hard nodules. Despite being limited to the skin, PN was noted to be associated with systemic diseases including diabetes and chronic renal failure. In previous smaller retrospective studies, several cardiac and vascular diseases were found more frequently in patients with PN. However, small cohort sizes, partially discrepant outcomes, missing data, and incomplete risk assessment limit these findings. MethodsElectronic health records (EHR)s of 64,801 patients (59.44% females) with PN and an equal sized propensity-matched control group were retrieved. In these cohorts, the risks to develop cardiac and vascular diseases and mortality following diagnosis of PN were determined. Sub-analyses included stratification for sex, ethnicity, and treatments. FindingsPN was associated with a higher risk for a broad range of acute cardiac events including heart failure and myocardial infarction. For example, the hazard ratio of myocardial infarction was 1.11 (95%-CI: 1.041-1.184, p=0.0015) following PN diagnosis. Also, all-cause mortality was higher in patients with PN. Further, chronic vascular as well as structural heart diseases, e.g., peripheral arterial disease, chronic ischaemic heart disease and valval disorders were found more frequently following a PN diagnosis. Risks were more pronounced in white and female patients. Having established an increased risk for death and cardiovascular disease, we next addressed if dupilumab that has been recently licenced for use in this indication can modulate these risks. The risk of death but not of any cardiovascular disease was slightly reduced in patients with PN treated with dupilumab as opposed to those treated with systemic therapies other than dupilumab. The study is limited by retrospective data collection and reliance on ICD10-disease classification. InterpretationPN is associated with higher mortality and an increased risk for the development of a wide range of cardiac and vascular diseases. Health care professionals should take this into account when managing patients with PN. FundingThis work was supported by the University of Lübeck, the Deutsche Forschungsgemeinschaft and the State of Schleswig-Holstein.

Organizational Demography and Gender Authority Gaps in Dutch Workplaces

Social stratification research increasingly draws attention to the role of workplaces for the (re)production of categorical inequalities. This article studies the relationship between differences between men’s and women’s chances of having a position of workplace authority – the gender authority gap – and the demographic characteristics of the organization they work in. Using unique linked employer-employee data representative of large workplaces in the Netherlands and individuals working in these organizations, I document larger gender authority gaps in organizations with larger shares of men and organizations where men have higher status than women in terms of other categorical distinctions, for example where their percentage of non-migrants is higher relative to women’s. Crucially, these findings are net of women’s and men’s individual status characteristics and human capital and related organizational characteristics. This article contributes to the literature on the gender authority gap by showing that women may be unable to reach desired jobs partially because of working in an organization with a particular demographic composition or intersection of status distinctions even when they have the qualifications to do so. In addition, the study contributes to the emerging relational inequalities literature that has thus far focused on earnings inequality by showing that predictions from this literature are consistent with the unequal distribution of desirable jobs.

Biogeography of intestinal mucus-associated microbiome: Depletion of genus Pseudomonas is associated with depressive-like behaviors in female cynomolgus macaques

IntroductionDepression is a debilitating and poorly understood mental disorder. There is an urgency to explore new potential biological mechanisms of depression and the gut microbiota is a promising research area. ObjectivesOur study was aim to understand regional heterogeneity and potential molecular mechanisms underlying depression induced by dysbiosis of mucus-associated microbiota. MethodsHere, we only selected female macaques because they are more likely to form a natural social hierarchy in a harem-like environment. Because high-ranking macaques rarely displayed depressive-like behaviors, we selected seven monkeys from high-ranking individuals as control group (HC) and the same number of low-ranking ones as depressive-like group (DL), which displayed significant depressive-like behaviors. Then, we collected mucus from the duodenum, jejunum, ileum, cecum and colon of DL and HC monkeys for shotgun metagenomic sequencing, to profile the biogeography of mucus-associated microbiota along duodenum to colon. ResultsCompared with HC, DL macaques displayed noticeable depressive-like behaviors such as longer duration of huddle and sit alone behaviors (negative emotion behaviors), and fewer duration of locomotion, amicable and ingestion activities (positive emotion behaviors). Moreover, the alpha diversity index (Chao) could predict aforementioned depressive-like behaviors along duodenum to colon. Further, we identified that genus Pseudomonas was consistently decreased in DL group throughout the entire intestinal tract except for the jejunum. Specifically, there were 10, 18 and 28 decreased Pseudomonas species identified in ileum, cecum and colon, respectively. Moreover, a bacterial module mainly composed of Pseudomonas species was positively associated with three positive emotion behaviors. Functionally, Pseudomonas was mainly involved in microbiota derived lipid metabolisms such as PPAR signaling pathway, cholesterol metabolism, and fat digestion and absorption. ConclusionDifferent regions of intestinal mucus-associated microbiota revealed that depletion of genus Pseudomonas is associated with depressive-like behaviors in female macaques, which might induce depressive phenotypes through regulating lipid metabolism.
