Maternal aggression in Wistar rats: effect of 5-HT2A/2C receptor agonist and antagonist microinjected into the dorsal periaqueductal gray matter and medial septum

Field: Neuroscience (Life Sciences)

The objective of the present study was to assess the role of the 5-HT2A/2C receptor at two specific brain sites, i.e., the dorsal periaqueductal gray matter (DPAG) and the medial septal (MS) area, in maternal aggressive behavior after the microinjection of either a 5-HT2A/2C receptor agonist or antagonist. Female Wistar rats were microinjected on the 7th postpartum day with the selective agonist alpha-methyl-5-hydroxytryptamine maleate (5-HT2A/2C) or the antagonist 5-HT2A/2C, ketanserin. The agonist was injected into the DPAG at 0.2 (N = 9), 0.5 (N = 10), and 1.0 µg/0.2 µl (N = 9), and the antagonist was injected at 1.0 µg/0.2 µl (N = 9). The agonist was injected into the medial septal area (MS) at 0.2 (N = 9), 0.5 (N = 7), and 1.0 µg/0.2 µl (N = 6) and the antagonist was injected at 1.0 µg/0.2 µl (N = 5). For the control, saline was injected into the DPAG (N = 7) and the MS (N = 12). Both areas are related to aggressive behavior and contain a high density of 5-HT receptors. Non-aggressive behaviors such as horizontal locomotion (walking) and social investigation and aggressive behaviors such as lateral threat (aggressive posture), attacks (frontal and lateral), and biting the intruder were analyzed when a male intruder was placed into the female resident's cage. For each brain area studied, the frequency of the behaviors was compared among the various treatments by analysis of variance. The results showed a decrease in maternal aggressive behavior (number of bites directed at the intruder) after microinjection of the agonist at 0.2 and 1.0 µg/0.2 µl (1.6 ± 0.7 and 0.9 ± 0.3) into the DPAG compared to the saline group (5.5 ± 1.1). There was no dose-response relationship with the agonist. The present findings suggest that the 5-HT2A/2C receptor agonist has an inhibitory effect on maternal aggressive behavior when microinjected into the DPAG and no effect when microinjected into the MS. Ketanserin (1.0 µg/0.2 µl) decreased locomotion when microinjected into the DPAG and MS, but did not affect aggressive behavior. We interpret these findings as evidence for a specific role of 5-HT2A/2C receptors in the DPAG in the inhibition of female aggressive behavior, dissociated from those on motor activity.
The Nuts and Bolts of Post-conflict Capacity Building : Practicable Lessons from East Timor

Field: Social Sciences (Social Sciences)

‘Capacity building’ has become a ubiquitous term in the international peacebuilding community. While the need for capacity building in post-conflict contexts is widely accepted, discussions rarely venture into what it is in practical and operational terms, and how it ought to be done. This article examines a major capacity building project in East Timor, focusing on capacity building as it occurs day to day and on the ground. Following a brief overview of the concept of capacity building, it identifies a number of key challenges that arise in initiatives in which internationals work directly with local actors to build their capacity. It then offers a set of concrete proposals, targeted at capacity builders and their managing institutions, for improved practice.
Three-chamber electrochemical reactor for selective lithium extraction from brine

Field: Chemical Engineering (Physical Sciences)

Efficient lithium recovery from geothermal brines is crucial for the battery industry. Current electrochemical separation methods struggle with the simultaneous presence of Na + , K + , Mg 2+ , and Ca 2+ because these cations are similar to Li + , making it challenging to separate effectively. We address these challenges with a three-chamber reactor featuring a polymer porous solid electrolyte in the middle layer. This design improves the transference number of Li + (t Li + ) by 2.1 times compared to the two-chamber reactor and also reduces the chlorine evolution reaction, a common side reaction in electrochemical lithium extraction, to only 6.4% in Faradaic Efficiency. Employing a lithium-ion conductive glass ceramic (LICGC) membrane, the reactor achieved high t Li + of 97.5% in LiOH production from simulated brine, while the concentrations of Na + K + , Mg 2+ , and Ca 2+ are below the detection limit. Electrochemical experiments and surface analysis elucidated the cation transport mechanism, highlighting the impact of Na + on Li + migration at the LICGC interface.
Development of Design Methodology for Rectangular Glass Supported on Three Sides to Resist Lateral Uniformly Distributed Loads

Field: Engineering (Physical Sciences)

The forthcoming version of Practice to Determine the Load Resistance of Glass in Buildings (E 1300-02) will contain several new features. These include new procedures to determine load resistance of laminated glass, revised procedures to determine load resistance of insulating glass, and procedures to determine load resistance of rectangular glass supported on 1, 2, and 3 sides. This paper discusses the development of load resistance charts for rectangular glass supported on three sides with one side free. It presents the nonlinear finite element model used to determine stresses and deflections. The load resistance charts use maximum edge stress as the criterion for determining load resistance. The value of maximum edge stress derives from a failure prediction approach for glass edges rather than surface stresses. The paper describes load-induced stresses along the edge of an unsupported side and over the glass surface for glass supported along three sides. It compares probability of breakage based upon surface stresses with that derived from the maximum edge stress criterion.
Short-term functional outcome after fast-track primary total knee arthroplasty: analysis of 623 patients

Field: Medicine (Health Sciences)

Background and purpose - Early functional outcome after total knee arthroplasty (TKA) has been described before, but without focus on the presence of certain functional recovery patterns. We investigated patterns of functional recovery during the first 3 months after TKA and determined characteristics for non-responders in functional outcome.Patients and methods - All primary TKA in a fast-track setting with complete patient-reported outcome measures (PROMs) preoperatively, at 6 weeks, and 3 months postoperatively were included. Included PROMs were Oxford Knee Score (OKS), Knee disability and Osteoarthritis Outcome Score Physical Function Short-Form (KOOS-PS), and EuroQol 5 dimensions (EQ-5D) including the self-rated health Visual Analogue Scale (VAS). Patients with improvement on OKS less than the minimal clinically important difference (MCID) were determined as non-responders at that time point. Characteristics between groups of responders and non-responders in functional recovery were tested for differences: we defined 4 groups a priori, based on the responder status at each time point.Results - 623 patients were included. At 6 weeks OKS, KOOS-PS, and EQ-5D self-rated health VAS were statistically significant improved compared with preoperative scores. The mean improvement was clinically relevant at 6 weeks for KOOS-PS and at 3 months for OKS. Patient characteristics in non-responders were higher BMI and worse scores on EQ-5D items: mobility, self-care, usual activities, and anxiety/depression.Interpretation - Both statistically significant and clinically relevant functional improvement were found in most patients during the first 3 months after primary TKA. Presumed modifiable patient characteristics in non-responders on early functional outcome were BMI and anxiety/depression.
Ubiquitination of gasdermin D N-terminal domain directs its membrane translocation and pore formation during pyroptosis

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract

Gasdermin D (GSDMD) is a critical mediator of pyroptosis, which consists of a N-terminal pore-forming domain and a C-terminal autoinhibitory domain. The free N-terminal domain (GD-NT), which is released through caspase-1/11 cleavage, exhibits distinct features from the full-length GSDMD (GD-FL), including oligomerization, membrane translocation and pore-formation. However, the underlying mechanisms are not well clarified. Here, we found that GD-NT, but GD-FL, was massively ubiquitinated in cells. The K63-linked polyubiquitination of GD-NT at Lys236/237 (human/mouse), catalyzed by TRAF1, directly its membrane translocation and pore-formation during pyroptosis. Inhibition of GD-NT ubiquitination via site mutation or the UBA1 inhibitor PYR-41 suppressed cell death in several pyroptosis cell models. Additionally, the application of PYR-41 in septic mice efficiently suppressed the release of IL-18 and TNF-⍺. Thus, GD-NT ubiquitination is a key regulatory mechanism controlling its membrane localization and activation, which may provide a novel target for modulating immune activity in pyroptosis-related diseases.
Novel Dual-Bed Reactors:  Utilization of Hydrogen Spillover in Reactor Design

Field: Chemical Engineering (Physical Sciences)

Hydrogen spillover over macroscopic distances was demonstrated and exploited in the design of two novel catalytic reactors for 1-butene isomerization. A dual-bed reactor containing separate zones of noble metal and bimetallic catalysts yielded activities up to 2.7 times greater than that of the noble metal alone. The noble metal catalyst contained palladium supported on graphitic carbon. The bimetallic catalyst contained a base metal, either iron or cobalt, and a lanthanide metal, either cerium or praseodymium, also supported on graphitic carbon. The bimetallic catalysts by themselves had no measurable activity at the current experimental conditions. Results from a dual-bed, dual-feed reactor using the same catalysts showed dramatic activity increases relative to controls. In this reactor, the hydrocarbon never contacted the noble metal catalyst, yet substantial hydrocarbon conversion was measured. No hydrocarbon conversion was detected when blank support replaced the bimetallic catalyst or when no material at all was placed above the noble metal catalyst. In both reactors, the activity increase was attributed to hydrogen spillover. That is, molecular hydrogen adsorbed and dissociated on the noble metal catalyst. The adsorbed atomic hydrogen was then transported via surface diffusion to the bimetallic catalyst, activating those sites. The results also demonstrated that a catalytic reaction may occur at distinctly different reactive sites and that catalysts may be selected to promote specific steps within the reaction.
Myasthenia gravis in pregnancy: a rare disorder with multidisciplinary management

Field: Medicine (Health Sciences)

Myasthenia gravis is a rare autoimmune disorder characterized by nicotinic acetylcholine receptor autoantibodies, affecting the neuromuscular transmission leading to progressive weakness. As this disease is seen in the reproductive age group, clinicians need to be aware of this condition and its multidisciplinary management which is the key to successful outcome. Myasthenia gravis especially when associated with pregnancy is a high-risk condition, that may affect both the mother and the fetus and may result in adverse outcome. The pregnancy course is unpredictable with MG.
Using a nanohybrid composite and diode laser to achieve minimally invasive esthetic anterior restorations.

Field: Dentistry (Health Sciences)

Developments in material science have contributed greatly to the evolution of composites during the past several decades. Most recently, nanohybrids and nanofilled direct composites have demonstrated the advantages of previous composite generations, such as strength, low wear, and polishability, but without many of the limitations. Concurrently, soft-tissue diode lasers also are among evolving dental products that can enable clinicians to offer less invasive restorative and esthetic treatments to patients.
Being a retailer: narratives not on display

Field: Business, Management and Accounting (Social Sciences)

Purpose The purpose of this paper is to explore the everyday tasks and activities undertaken by retailer entrepreneurs and owner/managers when they strategize. Specifically, it interrogates the nature of the intuitive, idiosyncratic strategic agency of a retail owner/manager. Design/methodology/approach Through adopting a combination of phenomenological and narrative approaches, focussing on illuminating the everyday operational and strategic practices of one retail entrepreneur and owner/manager, a richly contextualized, ideographic account of the procedures and outcomes of their strategizing is provided. Findings By revealing narratives that are seldom obvious – often kept behind the counter, and not on display – the authors are able to unravel the social reality of the retailer's decision-making, and the influences of identity, connections with customers and community, emotions and the spirit, and love and family. This study also illuminates how entrepreneurs retrospectively make sense out of the messiness of everyday life particularly when juggling the melding of personal and business realities. Research limitations/implications This paper explores the experiences and reflections of the decision-making of one retail entrepreneur manager within a particular business setting. However, the use of an ideographic approach allowed for an in depth investigation of the realities of strategic practices undertaken by a retail owner that may be extrapolated beyond this immediate context. Originality/value This paper develops original insights into the retailer as an individual, vis-à-vis an organization, as well as nuanced understanding of the actual nature of work undertaken by retail entrepreneurs and owner/managers. To this end, this paper contributes to the “strategy-as-practice” debate in the strategic management literature, and to narrative analysis and advances insights to the perennial question: “what is a retailer?”.
Research Article Association between host genetic polymorphisms and susceptibility to <i>Helicobacter</i> <i>pylori</i> infection: a systematic review protocol

Field: Medicine (Health Sciences)

Helicobacter pylori is a gram-negative, microaerophilic bacterium and an etiological agent of gastroduodenal diseases, including gastritis, peptic ulcers, mucosa-associated lymphoid tissue lymphoma, and gastric cancer.H. pylori affects approximately half of the global population.Most infected patients remain asymptomatic or exhibit non-severe gastric diseases.The clinical outcome of the infection is intricately associated with a delicate host-parasite relationship.Infected individuals may present a variety of immune and inflammatory responses influenced by genes that either attenuate or exacerbate the infection.Characterizing potential molecular biomarkers of the host could provide a significant contribution to precision medicine, assisting in the diagnosis, prognosis, and personalized therapeutic approaches for H. pylori infected patients.This systematic review protocol aims to provide a comprehensive and critical synthesis of the scientific evidence regarding genetic polymorphisms and their association with host H.C.O.Santos et al. 2susceptibility to H. pylori infection.This protocol has been registered in the International Prospective Register of Systematic Reviews with number CRD42023409085.It was prepared in accordance with the guidelines of the Joanna Briggs Institute for systematic review protocols concerning etiology and risk.The literature searches will be conducted in electronic bibliographic databases.The selection process will be conducted in pairs, using a double-blind format, and any discrepancies will be resolved by a third reviewer.After selection, the relevant data will be extracted and recorded in a designated form.This is designed to find genetic polymorphisms associated with specific clinical outcomes, potentially helping provide valuable insights for precision medicine, allowing the development of personalized and effective therapeutic approaches in patient treatment.
Mineral Composition and Monthly Variations of Dactyloctenium aegypticum (l.) beauv. in a Semi arid Grass Community

Field: Agricultural and Biological Sciences (Life Sciences)

Ecological study of Dactyloctenium aegypticum in semi arid grassland is described with a view to utilize it for the regional wasteland development. Dactyloctenium aegypticum is a dominant species. Maximum individual density was found nearly 40% of the total density in the community. Biomass was also found nearly 44% of the total biomass. The species was rich in Ca + content, less in P content. D. aegypticum owes its significance in the region as it forms a species for bioreclamation of salt affected soils. The soil in the region requires special management practices and areas unfit for agriculture can be utilized for pasture development.
The influence of behavioral biases on the trading decisions of equity fund investors: A case of British American (britam) Kenya Equity fund

Field: Economics, Econometrics and Finance (Social Sciences)

This paper set out to study behavioral biases of investors in the equity fund market and how they apply in our local situation. The objective of this study was to identify behavioral biases and phenomena present amongst investors in the equity fund market in Kenya and determine how these behavioral biases influence their trading decisions in terms of buying and selling of equity fund scheme shares. This study sought to identify if investors’ selling behavior is influenced by the disposition effect and loss aversion and if investors are irrational in their purchasing decisions by irrationally buying shares with high prices or buying shares based on how old the fund is rather than the fund’s performance. \nThe study was an exploratory study. It focused on the British American equity fund scheme as it has been and it still is, the largest equity fund scheme in Kenya, with the most investors. The British American equity fund scheme has a current market share of 54%. Secondary data was collected from British American’s equity fund data base and from their publicly available financial statements for the years 2008 to 2011. The data was analyzed using statistical tools such as charts and graphs and using regression analysis. \nThe study found that investors exhibited both rational behavior and irrational behavior in their trading decisions. It was found that there were a number of investors who were influenced by the disposition effect and by loss aversion in their selling/redemption decisions in that they sold fund shares quickly when prices increased slightly and held on to shares slightly longer when prices declined below the original fund share price of Kshs. 100. However, there were also a number of investors who retained their shares longer when prices were on an upward trend and sold them when prices had increased even further to higher levels, hence realizing more gains on redemption. With regard to purchasing decisions, the study found that investors were mostly rational, buying shares when prices declined. The study also found that investors purchased more shares in the fund when the performance of the fund improved i.e. when the fund made increased return/profits, which is also rational. It was noted however, that the number of fund shares issued decreased as the fund got older. This is in keeping with other studies that found that there is an irrational tendency of investors to purchase more shares from newer and younger equity fund schemes.
Mindfully Scrolling: Rethinking Facebook After Time Deactivated

Field: Social Sciences (Social Sciences)

Many people express concern that Facebook’s users are overly connected. This article examines responses to survey questions asked after a large random sample of American Facebook users had been paid to deactivate Facebook. We find a recurring discourse of mind including, for example, references to mindfulness. Using iterative qualitative coding, we ask what meanings and practices are invoked in this discourse. Furthermore, we critically assess the potential of what respondents describe to address the problems of overconnection. We find explicit awareness of the automaticity of use, the value and content of Facebook, and how it makes users feel. We find that users came to practice disconnection at many nested levels of vernacular affordances. Ultimately, we argue that Facebook has become a landscape trap, altering daily life such that individual practices, such as mindful scrolling, cannot overcome the overconnection problems it may create. Mindfulness in this discourse may be power, but it is power to avoid elements of Facebook, not power to transform it.
