What factors contribute to parental vaccine hesitancy for children aged 0–5 years?
Authors: Ebanks Christina
Published: October 2023

A growing proportion of children in England aged 0–5 years are not being vaccinated in line with the national immunisation schedule. Evidence suggests that this is, in part, due to parents declining all or some vaccinations. A deeper understanding of the reasons behind parental ‘vaccine hesitancy’ would enable effective health promotion approaches to ensure the success of childhood vaccination programmes. With this in mind, a literature review was conducted. Analysis of the selected papers identified emerging themes that contributed to parental vaccine hesitancy for children aged 0–5 years. These included a lack of parental perception that routine vaccines are needed; safety concerns for vaccines being offered; and a belief that a child’s immune system would be ‘overloaded’ if several vaccines were given at one time. The findings suggest a collaborative approach between parents, health professionals and stakeholders is needed to tackle the problem of parental vaccine hesitancy.
The Hardness of Boride Layer on the S45C Iron (A preliminary study on surface hardening of ferrous material)
Authors: S Sutrisno , Soegijono Bambang
Published: October 2023

Abstract - The property such as microhardness of boridelayer formed on S45C iron was investigated. Boronizing was carried out in a solid medium consisting of nano size powders of 50% B4C as a donor, 45% SiC as a diluent, and 5% KBF4 as an activator treated at the temperature of 10000C for 8 hours. The phases that were formed on the substrate was found as Fe2B and FeB layer that had smooth and flate shape morphology. The hardness of boride layer on S45C was over 2000 HV, while the hardness of untreated S45C iron was about 196,39 HV. Depending on process time and temperature, the depth of boride layer ranges from 25 to 55 μm, leading to a diffusion controlled process.Keywords : Boronization, hard layer, heat treatment, B4C.KBF4.SiC powder, low carbon steel.

Utilization of Acoustic Wave Velocity for Permeability Estimation in Static Reservoir Modeling: A Field Case
Authors: Prakoso Suryo , Prakoso Suryo , Burhannudinnur Muhammad , Irano Teddy , Herdiansyah Firman
Published: October 2023

Several researches have shown that P-wave velocity carries information on the complexity of the rock's pore geometry and pore structure. Their complexity can be characterized by critical porosity. Therefore, the P-wave velocity is used to estimate permeability. This research uses data taken from the Tomori formation from Banggai-Sula basin, Central Sulawesi, which is a carbonate rock reservoir. Also, this research aims to obtain a 3D permeability model by using acoustic wave velocity cube data. The results show that permeability can be modeled well using acoustic wave velocity data. Furthermore, compared to the raw data log of permeability, the modeling results using wave velocity based on critical porosity show good results. This method is another alternative to permeability modeling if acoustic wave velocity cube data is available

Afterlives of Slavery in Early Liberia
Authors: Stango Marie
Published: October 2023

Abstract: This article examines letters written by formerly enslaved settlers in Liberia during the mid-nineteenth century to examine two aspects of the afterlives of slavery. Manumitted settlers in Liberia, as formerly enslaved people, connected to audiences in the United States in different ways from freeborn settlers, who were more likely to make multiple transatlantic voyages, or had commercial connections with the United States. In this afterlife of slavery in Liberia, the letter writers examined here relied on relationships with their former enslavers to remain connected to kin and community in the United States. In a second evocation of afterlives, these letters show how settlers' conceptualizations of home pressed beyond both the United States and Liberia. For them, "home" was reunification with family–a family that could only be made whole through a belief in a shared spiritual afterlife.
Broadband and strength-switchable circular dichroism in a Ge2Sb2Te5-based metasurface
Authors: Wang Zhihong , Zhao Songliang , Jiang Huan , Peng Kangzhun , Zhao Weiren
Published: October 2023

Circular dichroism (CD) is highly required in the applications of biological detection and analytical chemistry. In this paper, we achieved a giant, broadband, and strength-switchable CD effect in a quadruple z-shaped Ge2Sb2Te5 (GST) metasurface. At the amorphous state of GST (a-GST), the giant CD reaches 0.92 and the width of the absorption >0.80 is about 100 nm. The giant and broadband CD originates from polarization selective excitations of Mie resonances and the coupling between subunit resonators. With the transition from a-GST to crystalline GST, CD could be dynamically switched from 0.92 to 0.05. The GST-based metasurfaces with giant and wide-range switching CD will promote the development of active chiral devices.

Authors: Zhang Guozhuo , Wang Xu , Zheng Dezhi , Cui Han , Wang Yun
Published: October 2023

Aiming at the miniaturization and rapid imaging requirements of a portable confocal Raman system, a MEMS-based portable confocal Raman spectroscopy rapid imaging method is proposed in this study. This method combines the dual 2D MEMS mirror scanning method and the grid-by-grid scanning method. The dual 2D MEMS mirror scanning method is used for the miniaturization design of the system, and the grid-by-grid scanning method is used for rapid imaging of Raman spectroscopy. Finally, the rapid imaging and miniaturization design of a portable confocal Raman spectroscopy system are realized. Based on this method, a portable confocal Raman spectroscopy rapid imaging system with an optical probe size of just 98mm×70mm×40mm is constructed. The experimental results show that the imaging speed of the system is 45 times higher than that of the traditional point-scan confocal Raman system, and the imaging speed can be further improved according to the requirements. In addition, the system is used to swiftly identify agate ore, and the material composition distribution image over a 126µm2×126µm2 region is obtained in just 16 min. This method provides a new solution for the rapid imaging and miniaturization design of the confocal Raman system, as well as a new technical means for rapid detection in deep space exploration, geological exploration, and field detection.
Application of multivariate time-series model for high performance computing (HPC) fault prediction
Authors: Pei Xiangdong , Yuan Min , Mao Guo , Pang Zhengbin
Published: October 2023

Aiming at the high reliability demand of increasingly large and complex supercomputing systems, this paper proposes a multidimensional fusion CBA-net (CNN-BiLSTAM-Attention) fault prediction model based on HDBSCAN clustering preprocessing classification data, which can effectively extract and learn the spatial and temporal features in the predecessor fault log. The model can effectively extract and learn the spatial and temporal features from the predecessor fault logs, and has the advantages of high sensitivity to time series features and sufficient extraction of local features, etc. The RMSE of the model for fault occurrence time prediction is 0.031, and the prediction accuracy of node location for fault occurrence is 93% on average, as demonstrated by experiments. The model can achieve fast convergence and improve the fine-grained and accurate fault prediction of large supercomputers.
Socioeconomic, demographic and geographic determinants of food consumption in Mexico
Authors: Guibrunet Louise , Ortega-Avila Ana G. , Arnés Esperanza , Mora Ardila Francisco
Published: October 2023

What people eat affects public health and human wellbeing, agricultural production, and environmental sustainability. This paper explores the heterogeneity of food consumption patterns in an ecologically and culturally diverse country. Using a latent class approach (which creates clusters of individuals with homogeneous characteristics), we analyse a food questionnaire (from the National Health and Nutrition Survey) applied across Mexico. We identify four clusters of food consumption (staple, prudent, high meat and low fruit) and find that belonging to these clusters is determined by socioeconomic, demographic (age, sex) and geographic (region, urban/rural) characteristics. Maize and pulses tend to constitute a larger proportion of the diet of poor, rural populations living in the south, while urban populations eat more varied foods, including ingredients whose production systems tend to exert more pressure on natural resources (for instance, meat). Despite the importance given in the literature to the Mexican gastronomy and its diverse traditional regional diets, we find that only 6% of the population adopts a food consumption pattern resembling the traditional Mexican diet. Instead, most of the Mexican population has a food consumption pattern resembling a western diet, which is problematic in terms of public health and environmental sustainability.

European dry thin-soil calcareous grasslands (alvars) are species-rich semi-natural habitats. Cessation of traditional management, such as mowing and grazing, leads to shrub and tree encroachment and the local extinction of characteristic alvar species. While soil microbes are known to play a critical role in driving vegetation and ecosystem dynamics, more information is needed about their composition and function in grasslands of different dynamic stages. Here we assess the composition of soil fungal, prokaryotic, and plant communities using soil environmental DNA from restored alvar grasslands in Estonia. The study areas included grasslands that had experienced different degrees of woody encroachment prior to restoration (woody plant removal and grazing), as well as unmanaged open grasslands. We found that, in general, different taxonomic groups exhibited correlated patterns of between-community variation. Previous forest sites, which had prior to restoration experienced a high degree of woody encroachment by ectomycorrhizal Scots pine, were compositionally most distinct from managed open grasslands, which had little woody vegetation even prior to restoration. The functional structure of plant and fungal communities varied in ways that were consistent with the representation of mycorrhizal types in the ecosystems prior to restoration. Compositional differences between managed and unmanaged open grasslands reflecting the implementation of grazing without further management interventions were clearer among fungal, and to an extent prokaryotic, communities than among plant communities. While previous studies have shown that during woody encroachment of alvar grassland, plant communities change first and fungal communities follow, our DNA-based results suggest that microbial communities reacted faster than plant communities during the restoration of grazing management in alvar grassland. We conclude that while the plant community responds faster to cessation of management, the fungal community responds faster to restoration of management. This may indicate hysteresis, where the eventual pathway back to the original state (grazed ecosystem) differs from the pathway taken towards the alternative state (abandoned semi-natural grassland ecosystem).
Assessment of the functional state of the back muscles in girls with C-shaped low-grade scoliosis in a tensiomyographic image: An observational cross-sectional study
Authors: Szurmik Tomasz , Ogrodzka-Ciechanowicz Katarzyna , Kurzeja Piotr , Gąsienica-Walczak Bartłomiej , Prusak Jarosław , Bibrowicz Karol
Published: October 2023

Purpose

The study aimed to test the feasibility of using tensiomyography to assess the functional status of the latissimus dorsi and erector spinae muscles in girls with C-shaped low back scoliosis.

Materials and methods

Twenty-five girls aged 13–15 took part in an observational (cross-sectional) study. The examination involved measurements using the tensiomyography method (TMG). Two groups of muscles were tested: latissimus dorsi and erector spinae on the concave and convex side of low-grade scoliosis. The following indicators were analyzed: Td–delay time, Tc–contraction time, and Dm–maximal muscle displacement.

Results

The analysis of Td revealed that values of this variable on the concave side were slightly lower compared to the convex side in both tested groups of muscles. Similarly, Tc values on the concave side were slightly lower than on the convex side of the curvature in both groups of muscles. In the case of Dm, lower displacement values and, consequently, greater muscle rigidity were observed on the concave side of the latissimus dorsi and the convex side of the erector spinae.

Conclusions

The TMG method can be potentially used to diagnose the functional condition of muscles in patients with low-grade scoliosis. There were differences between the functional condition of the muscles on the concave and convex sides of the curvature.

Authors: Wang Yuanyuan , Li Li , Mu Yanling , Wang Shanglong , Li Xin , Zong Jiancheng , Zou Shengcan , Liu Zimin , Gao Dehai
Published: October 2023

Aim

In vivo and in vitro toxicity tests of JointAlive® were studied in animal models to support the safe use of JointAlive® as a drug for knee osteoarthritis treatment.

Methods

The acute toxicity study in Sprague Dawley (SD) rats was conducted at a 20 g/kg bw/day dose of JointAlive®. For 13-week subchronic toxicity tests, SD rats were orally dosed daily with 0.5, 1.5 and 5 g/kg bw/day of JointAlive®. To assess the potential genotoxicity, Ames test, cellular chromosome aberration and mouse micronucleus test in vivo were carried out.

Results

Based on a lack of notable findings other than histopathology finding of co-incidental prostate inflammation at the high dose, the “No Observed Adverse Effect Level (NOAEL)” of JointAlive® was concluded as 5 g/kg bw/day in males and females. Results also indicated that JointAlive® has no risk of genotoxicity.

Conclusions

General toxicity and genotoxicity studies empirically demonstrated that JointAlive® poses a low risk of potential health risks, providing safety supports for the application of JointAlive® as a potential drug candidate to treat knee osteoarthritis.
Insights into the microbiological and virulence characteristics of bacteria in orthopaedic implant infections: A study from Pakistan

Published: October 2023

The exponential increase in the prevalence of multidrug resistant bacteria has resulted in limiting surgical treatment options globally, potentially causing biofilm-related complications, implant failure, and severe consequences. This study aims to isolate and characterize bacteria from post-surgical orthopaedic implant infections and screening for multiple antibiotic resistance. A cross-sectional study was conducted, involving isolation of forty-four dominant pathogenic bacterial isolates from 16 infected implant samples from across Islamabad and Rawalpindi. Out of forty-four, 38% cocci and 61% bacilli were obtained. Approximately 90% of isolates showed multiple antibiotic resistance (MAR) index of more than 0.2. Eleven strains were identified via 16S rRNA gene sequencing as Pseudomonas aeruginosa, Bacillus spp., Planococcus chinensis, Staphylococcus, Escherichia coli and Enterobacter cloacae. The bacterial strain E. coli MB641 showed sensitivity to Polymyxin only, and was resistant to all other antibiotics used. Maximum biofilm forming ability 0.532 ± 0.06, 0.55 ± 0.01 and 0.557 ± 0.07 was observed in Pseudomonas aeruginosa MB663, Pseudomonas aeruginosa MB664 and Bacillus spp. MB647 respectively after 24 hours of incubation. EPS production of bacterial strains was assessed, the polysaccharides and protein content of EPS were found to be in the range of 11–32 μg/ml and 2–10 μg/ml, respectively. Fourier transform infrared spectroscopic analysis of EPS showed the presence of carbohydrates, proteins, alkyl halides, and nucleic acids. X-ray diffraction analysis revealed crystalline structure of EPS extracted from biofilm forming bacteria. These findings suggest a high prevalence of antibiotic-resistant bacteria in orthopaedic implant-associated surgeries, highlighting the urgent need for ongoing monitoring and microorganism testing in infected implants.
Empowering neighbourhood music: Leveraging professional recording studio and entrepreneurial strategies in a minority Title 1 school1
Authors: DeVito Donald , Ruiz José Valentino
Published: October 2023

To reimagine pedagogy, creativity and learning in popular music education, various interdisciplinary theories and models of culture and musical practice can be mobilized. One such approach is the ‘professional recording studio’ (PRS) pedagogical approach. This focuses on developing students’ artistic identities through culturally relevant local neighbourhood music in a school with a low socio-economic status and a 99 per cent minority population. The PRS approach incorporates a wide range of music, including traditional music from the predominantly Black community and student compositions that incorporate local rhythms, riffs and playground music. By giving a voice to the underserved community, this approach aims to empower students and connect their musical experiences with their cultural heritage. The PRS approach can be examined through the lens of facilitated teaching approaches found in the field of community music and community arts entrepreneurialism.
‘I’d castrate you and marry you in a heartbeat’: Queerness, quality and classics in Succession
Authors: Beattie Melissa
Published: October 2023

Critically acclaimed transnational (United States/United Kingdom) drama Succession (2017–23) utilizes classical references combined (arguably juxtaposed) with queerness and insecurities about masculinity/-ties and orientation within its satirical representation of corporate culture. While connecting quality television to British period dramas and queerness, especially on HBO, is relatively common, the series uses phallic discourses not only to illustrate and satirize the toxic masculinity present in its pseudo-royal corporate culture but also to show the complexities of a queer ‘will-they/won’t-they’ couple – Tom Wambsgans (Matthew Macfadyen) and Greg Hirsch (Nicholas Braun) – within this environment. This article will engage in a close reading of representative scenes from the first three series in order to analyse the variety of phallic and other gendered or sexualized discourses within the series which represent contemporary sociocultural anxieties over masculinity/-ties and power as connected with genitalia, castration and/or orientation. This will include discussion and historical contextualization of castration with regard to queerness and different modes of (non-procreative) power, the analogy made to Nero and his castrated slave/spouse Sporus in which the title quote appears in the series as a declaration of love, and discussion of transgression, power and the series’ pseudo-royal court/corporation. The article will illustrate how the series utilizes these discourses to acquire and express the distinction required for quality TV while simultaneously interrogating, satirizing and critiquing the toxicity of contemporary corporate culture with regard to gender and orientation.
Acessibilidade e inclusão na graduação em ciências contábeis: Uma discussão acerca do conhecimento e envolvimento

Barreiras diversas limitam a permanência e conclusão do ensino superior às pessoas com deficiência, e sua eliminação é essencial para a inclusão e a garantia de direitos fundamentais como a educação e justiça social. Por meio das lentes das dimensões da acessibilidade problematizamos como a acessibilidade é promovida e percebida nos cursos de Ciências Contábeis de uma universidade pública federal mineira. Na discussão qualitativa, com uso da Análise de Conteúdo, atribuiu-se significados aos termos e expressões usados por um corpus de 29 entrevistados que relataram seu conhecimento e envolvimento com o processo de inclusão na instituição e cursos. As falas revelaram o ‘fenômeno da negação’ dado o predomínio do advérbio ‘não’ sobre o conhecimento de práticas inclusivas nas diferentes dimensões da acessibilidade. Também predomina a negação quanto ao envolvimento, sobretudo em ações para promoção da acessibilidade comunicacional, metodológica e atitudinal dentro e fora de sala de aula. Confirmamos dificuldades durante o percurso formativo de discentes, em relação à acessibilidade arquitetônica [sinalização irregular, estacionamento sem calçamento, elevadores defeituosos], instrumental [necessidade de equipamentos, e material bibliográfico em língua de sinais e braile, demanda por intérpretes]; metodológica [despreparo docente, atitudes capacitistas]; e falhas de comunicação entre a direção, coordenação, Depae, docentes e discentes.
Rural district leaders and place in the shadow of the pandemic: Refining the conceptualization of leadership of place as caring
Authors: Walls Jeff , Zuckerman Sarah J.
Published: October 2023

The COVID-19 pandemic heightened the tensions between rural community needs and politicized state-level school closure mandates. District leaders faced competing demands of meeting the basic needs of vulnerable families, supporting the mental health of students and teachers, protecting the health of all community members, and creating new opportunities for learning. This study examines how rural district leaders responded to these challenges through the lens of caring. This lens highlights how district leaders responded to their contexts, as well as their perceptions of student, family, and staff needs in ethically grounded and politically savvy ways. We draw on semi-structured interviews with 12 rural district leaders in eight districts. District leaders in this study described caring as something that is intentionally enacted and identified several aspects that contributed to a caring district: a welcoming culture, taking an interest in individuals, prioritizing wellbeing, developing relationships, extending empathy and grace for people, and helping individuals see themselves as part of a larger community. Leaders made efforts to set the tone for and model care, build relationships with students, teachers, parents, and community members, and enact servant leadership to support others. We conclude by examining the ways that applying an ethic of care illustrates how leaders identify needs and the strategies they use to respond to those needs in a responsive, place-attuned way.
Contesting Religious Truth
Authors: Drews Wolfram
Published: October 2023

Abstract

Christian theologians were involved in anti-Jewish arguments almost since the ‘parting of the ways’ of the two religions. In late antiquity and the early middle ages, anti-Jewish arguments were based almost exclusively on Biblical quotations, which were adduced as evidence meant to substantiate the Christian interpretation of scripture. It was only in the scholastic period that new forms of evidence were included in the traditional argument Adversus Iudaeos, which were derived from the recourse to reason. The Jewish figures presented by Christian authors within their writings are constructed entirely according to Christian assumptions and prejudices; only rarely do we get any real Jewish voices representing points of view close to any kind of Jewish reality. This only changed when growing numbers of Jews converted to Christianity in the high middle ages; Jewish converts drew the attention of Christian authorities to rabbinic literature. At first, the Talmud was targeted as a sinister text allegedly undermining theological truth, but later it was appropriated by Christian propagandists, who tried to base their anti-Jewish arguments on the post-biblical canon of Rabbinic Judaism. The article analyses the gradual expansion of anti-Jewish evidence; in particular, it highlights turning points when anti-Jewish strategies tried to include new methods and media to substantiate the credibility of Christian claims to monopolise religious truth. The Jewish side reacted against such attempts by reinterpreting and rewriting the history of anti-Christian Jewish arguments, notably on the occasion of the Paris Talmud trial. The redirection of Christian-Jewish arguments in the high middle ages provides ample evidence for the study of contesting truths, the substantiation and subversion of validity claims, as well as the rewriting of history in order to further political aims.
Wirtschaftssanktionen im 13. Jahrhundert
Authors: Berger Maximiliane
Published: October 2023

Abstract

The history of medieval economic sanctions is currently both known and unknown. Many instances of their deployment have been acknowledged or analysed in the context of the conflicts they were part of, like the 1205/1206 blockade of the Rhine as an element in the struggle between Philipp of Swabia and Otto of Brunswick. On the other hand, research in Medieval Studies that puts economic sanctions centre stage is still an emerging field. This paper argues that a broader investigation of episodes of economic sanctioning in the narrative sources is a sensible next step to develop this field, since it would bring the triple advantages of expanding its current geographical and prosopographical scope beyond the ecclesiastic Mediterranean ( 1 ), of putting its currently prevailing focus on normative texts into context ( 2 ), and of obviating the more unnecessary pessimisms currently characterising evaluations of medieval economic sanctions ( 3 ). To show the potential of narrated medieval sanctions episodes to inform our understanding of economic thinking around medieval economic sanctions, three examples from 13th-century historiography are analysed: the above-mentioned blockade of the Rhine, a smugglers’ tale in Matthew Paris’s ‘Cronica Majora’ against the backdrop of papal embargo legislation, and Salimbene of Parma’s report on third-party participation in a Venetian blockade of the river Po.
New and Old Letter Types in the Corpus of Julian the Apostate ( 361–363 )
Authors: Neil Bronwen
Published: October 2023

Abstract

The emperor Julian’s career as a letter writer began long before his brief term as sole ruler of the united Roman empire from 361 to 363. In the surviving collection of 82 letters, only 73 were deemed authentic by their editor Emily Wilmer Cave Wright in the 1923 Loeb edition. The remaining nine she deemed apocryphal. This paper looks at two methodological issues associated with Julian’s letter collections. What grounds should the modern scholar use to discern authentic from forged letters; and were Julian’s letters of the same types as Christian letters of Late Antiquity or were they closer to Classical models? A third question arises from a survey of Julian’s epistolary addressees. These reveal a diverse network of people of various levels of status, including Basil, bishop of Caesarea, the Jews of Alexandria, and a priestess of Demeter and Cybele. How does this diversity compare with the correspondence of ( Christian ) emperors and bishops of the fourth century? I aim to answer these questions by considering those letter types in Julian’s letter corpus that were new in the fourth century, such as letters of recommendation for travellers and letters to religious groups, and others more familiar, that is, letters of friendship and letters of consolation. The overarching hypothesis is that Julian was inspired to write and have collected his public and personal letters in the same way as the Christian bishops whom he knew and with whom he corresponded, notably Bishop Basil of Caesarea.
Tithes in the Long 10th Century
Authors: Patzold Steffen
Published: October 2023

Abstract

This article explores the question of how tithing rights in the dioceses of Freising and Mâcon developed between the ninth and eleventh centuries. I argue contrary to previous research that in these two dioceses, the tithes at local churches did not fall into the hands of the laity already in the Carolingian period, based on ideas of ‘Eigenkirchenrecht’. Instead, we can observe how, from the later ninth century onwards, bishops themselves detached tithing rights from baptismal churches and allocated them to other, minor churches, to foster them economically. In the course of the tenth century, bishops then also gave tithing rights – without any church – to laymen, in Freising at first usually in the context of exchanges. In the second half of the eleventh century, in documents from the diocese of Mâcon, tithes in lay hands were usually presented as a sinful result of alienation; they were ‘returned’ to the cathedral ( or bought back by the bishops ). In the course of this, however, tithing rights that actually had been allocated to baptismal churches in the ninth century, now passed into the hands of the cathedral chapter or the bishop.
The Earliest Form and Function of the ‘Admonitio synodalis’ *
Authors: West Charles
Published: October 2023

Abstract

This article examines a text known as the ‘Admonitio synodalis’ as evidence for episcopal expectations of local priests in the tenth and eleventh centuries. The ‘Admonitio’ is generally considered a stable text that represented and fostered continuity within the Church, but this article highlights instead its early development. It begins by identifying a previously unedited version of the text found in some tenth-century manuscripts, arguing that this long recension is the closest to the original form. It then turns to how the text was adapted in the tenth century, notably by Bishop Rather of Verona. It finally examines the changes made to the text when it was incorporated into the liturgy of synodal ordines in the early eleventh century. A transcription of the tenth-century recension, based on a Brussels manuscript, is provided as an appendix.
Study on the influence of surface roughness on tensile and low-cycle fatigue behavior of electron beam melted Ti‐6Al‐4V
Authors: Yang Dongye , Si Ke , Tian Wenqi , Zhang Xinqi
Published: October 2023

Surface quality is a key factor in determining the mechanical performance of metallic materials. In this study, the influence of surface roughness on quasi-static mode tensile and low fatigue behavior of electron beam melted (EBMed) Ti‐6Al‐4V was studied. The results showed that the microstructure of the EBMed Ti‐6Al‐4V is mainly composed of α and β phases. It was found that the yield strength of the as-polished EBMed sample was about 200 MPa higher than the original EBMed sample, and the fatigue life was three times that. The fatigue crack initiation and propagation were explored, and it was found that the fatigue life was reduced on account of the thermal stress concentration that was generated as a result of the solidification shrinkage and the local stress concentration.
Malignant hyperthermia: Report on a successful rescue of a case with the highest temperature of 44.2°C
Authors: Lan Haiyan , Duan Gongchen , Zuo Yunxia , Lou Tianzheng , Xu Junlong , Shao Chuxiao , Wu Jimin
Published: October 2023

Malignant hyperthermia (MH) is an inherited skeletal muscle disorder caused primarily by a genetic mutation, usually in the calcium channel gene of the muscle. This mutation can lead to muscle hypersensitivity to volatile anesthetics (such as sevoflurane) and the depolarizing muscle relaxant succinylcholine, resulting in hyperthermia, muscle stiffness, metabolic disturbances, and other severe physiological reactions. This condition may prove fatal unless it is recognized in its early stages and treatment is administered promptly and aggressively. We report a 13-year-old adolescent who underwent laparoscopic appendectomy and developed MH after the use of inhalational anesthetics, manifested by unremitting hyperthermia with a maximum temperature of 44.2°C, muscle rigidity, tachycardia, hypercapnia; and malignant arrhythmias, cardiogenic shock, hyperkalemia, metabolic, and respiratory acidosis. After early and timely recognition, multidisciplinary management and administration of dantrolene, the case was successfully treated. Exome sequencing revealed a point mutation (amino acid change) on the RYR1 gene: c.12700G>C(p.Val4234Leu). Due to the lack of ready-made dantrolene in our hospital, the patient in this case received dantrolene treatment only 6 h after the first observation of high body temperature. We review the development of the disease and summarize the success of treatment and what can be done to improve the chances of saving the patient’s life if dantrolene is not available in time.

Social and Emotional Learning: Integrating a Catholic Christian Framework
Authors: Piteo Sister Elena Marie
Published: October 2023

This article develops an enriched framework for social and emotional learning that integrates the philosophy and theology of Saint Thomas Aquinas and current findings of psychological, developmental, and educational theories and empirical studies. The framework demonstrates that there are three key areas of social and emotional learning: (1) self-reflection, (2) virtue development, and (3) relational development. Furthermore, it explains that in order to achieve a fully integrated vision, these areas need to include biophysical, psychosocial, and spiritual elements of cognition, emotion, and social development. This framework has implications for education and psychotherapy. The article argues that a Thomistic-inspired framework has significant advantages for understanding social and emotional development because of its holistic treatment of the human person. Formation of the student is approached through a distinct Catholic Christian focus on the dignity of the human person as one made in the image and likeness of God and called to share in eternal beatitude with God. This framework of social and emotional development integrates science and philosophy and offers a Catholic Christian perspective on the need for divine revelation and Christ's gift of grace.

TheDrosophilamushroom body (MB) is an important model system for studying the synaptic mechanisms of associative learning. In this system, coincidence of odor-evoked calcium influx and dopaminergic input in the presynaptic terminals of Kenyon cells (KCs), the principal neurons of the MB, triggers long-term depression (LTD), which plays a critical role in olfactory learning. However, it is controversial whether such synaptic plasticity is accompanied by a corresponding decrease in odor-evoked calcium activity in the KC presynaptic terminals. Here, we address this question by inducing LTD by pairing odor presentation with optogenetic activation of dopaminergic neurons (DANs). This allows us to rigorously compare the changes at the presynaptic and postsynaptic sites in the same conditions. By imaging presynaptic acetylcholine release in the condition where LTD is reliably observed in the postsynaptic calcium signals, we show that neurotransmitter release from KCs is depressed selectively in the MB compartments innervated by activated DANs, demonstrating the presynaptic nature of LTD. However, total odor-evoked calcium activity of the KC axon bundles does not show concurrent depression. We further conduct calcium imaging in individual presynaptic boutons and uncover the highly heterogeneous nature of calcium plasticity. Namely, only a subset of boutons, which are strongly activated by associated odors, undergo calcium activity depression, while weakly responding boutons show potentiation. Thus, our results suggest an unexpected nonlinear relationship between presynaptic calcium influx and the results of plasticity, challenging the simple view of cooperative actions of presynaptic calcium and dopaminergic input.

HACE1 is a HECT family E3 ubiquitin–protein ligase with broad but incompletely understood tumor suppressor activity. Here, we report a previously unrecognized link between HACE1 and signaling complexes containing mammalian target of rapamycin (mTOR). HACE1 blocks mTORC1 and mTORC2 activities by reducing mTOR stability in an E3 ligase‐dependent manner. Mechanistically, HACE1 binds to and ubiquitylates Ras‐related C3 botulinum toxin substrate 1 (RAC1) when RAC1 is associated with mTOR complexes, including at focal adhesions, leading to proteasomal degradation of RAC1. This in turn decreases the stability of mTOR to reduce mTORC1 and mTORC2 activity. HACE1 deficient cells show enhanced mTORC1/2 activity, which is reversed by chemical or genetic RAC1 inactivation but not in cells expressing the HACE1‐insensitive mutant, RAC1K147R. In vivo, Rac1 deletion reverses enhanced mTOR expression in KRasG12D‐driven lung tumors of Hace1−/− mice. HACE1 co‐localizes with mTOR and RAC1, resulting in RAC1‐dependent loss of mTOR protein stability. Together, our data demonstrate that HACE1 destabilizes mTOR by targeting RAC1 within mTOR‐associated complexes, revealing a unique ubiquitin‐dependent process to control the activity of mTOR signaling complexes.

Desmanthus virgatus is a perennial forage legume used as a livestock feed source. Seeds of this species are physically dormant and thus, propagation is difficult. The dormancy also impacts the routine viability monitoring of genebank accessions. The present study investigated
different methods to break dormancy in seeds collected from various locations at different times. The result showed that most pre-treatments significantly increased germination percentage. Accessions treated with concentrated sulphuric acid (25 or 30 minutes) followed by sandpaper scarification
showed the highest proportion of normal seedlings (94.6 and 96%). Boiling water (2.3 or 3 minutes) was also effective in all accessions except for accession 331. However, accessions treated with hot water (3, 5 or 8 minutes) had a considerable proportion of hard seeds. The proportion of dead/abnormal
seedlings was high in seeds treated with a hot wire in all accessions, ranging from 27.5 (accession 15489) to 75.5% (accession 16). The untreated seeds remained hard at the final germination count. We conclude that it is important to use concentrated sulphuric acid and mechanical scarification
with sandpaper to break the dormancy for the species to enhance germination, obtain uniform field stands and make wise decisions during storage.
HERMENÉUTICA BÍBLICA EN CONTEXTOS DE CONFLICTO ARMADO. EL CASO COLOMBIANO
Authors: Casas Ramírez Juan Alberto
Published: October 2023

La matriz religiosa, de corte cristiana y mayoritariamente católica, con la creciente emergencia de grupos evangélicos de tradición pentecostal y neopentecostal, ha jugado un papel fundamental en el desarrollo del conflicto armado en Colombia. Por una parte, llegó a propiciar discursos de inspiración bíblica que legitimaban o toleraban la violencia con el fin de defender y mantener estructuras sociales y culturales tradicionalistas; de otra, ha sido impulsora o mediadora de acciones que buscan la paz, la reconciliación y la reparación de las víctimas. En este último sentido, los procesos de lectura bíblica realizados con comunidades afectadas y victimizadas, en contextos de conflicto armado, han sido fuente para la construcción colectiva de la memoria histórica de los acontecimientos, medio de resignificación sanadora del propio trauma, lugar existencial de acogida y apertura a la diversidad y a la pluralidad, generadores de estrategias de reparación, no repetición y rehabilitación personal y comunitaria.

Introducción: La fractura de cadera es un factor independiente que aumenta la morbimortalidad. El objetivo de este estudio retrospectivo fue determinar la morbimortalidad en ancianos con fracturas intertrocantéricas de cadera tratadas con clavos cefalomedulares.

Materiales y Métodos: Se analizó a pacientes tratados con clavo cefalomedular por fractura intertrocantérica de cadera, entre 2018 y 2021, y un seguimiento mínimo de 12 meses. Se registraron: datos demográficos, comorbilidades, capacidad funcional con el Índice de Movilidad de Parker, complicaciones y tasa de mortalidad a los 12 meses y al final del seguimiento. Se identificaron las variables independientes relacionadas con complicaciones o muerte.

Resultados: Se incluyó a 68 pacientes (seguimiento medio 23 meses). La tasa de complicaciones fue del 8,8%: infección urinaria, neumonía, trombosis venosa profunda y tres pérdidas de fijación del tornillo cefálico. Al comparar pacientes con complicaciones o sin ellas, hubo diferencias significativas en la edad cuando se produjo la fractura. Las tasas de mortalidad anual y al concluir el estudio fueron del 2,9% y29,4%, respectivamente. Las diferencias fueron significativas en la incidencia de comorbilidades renales, demencia, el Índice de Comorbilidad de Charlson >4 y el puntaje de Parker <5 en quienes fallecieron. El puntaje de Parker <5 fue la variable independiente relacionada con muerte.

Conclusiones: Las tasas de complicaciones y de mortalidad a los 12 meses del tratamiento de las fracturas intertrocantéricas inestables de cadera con clavos cefalomedulares es aceptable en ancianos. El riesgo de muerte aumenta significativamente si el puntaje de Parker es <5 antes de la fractura.

Published: October 2023

Introducción: Los implantes semiconstreñidos en la artroplastia total de rodilla están indicados cuando hay compromiso de la estabilidad de la rodilla, ya sea en cirugías primarias o de revisión. Materiales y Métodos: Se evaluó a 43 pacientes tratados con implantes de constricción condilar varo-valgo, en una misma institución, por el mismo equipo quirúrgico, entre 2015 y 2022. Resultados: Los resultados en las escalas de función WOMAC, KSS y Oxford fueron buenos/muy buenos. Los puntajes fueron menores en pacientes >75 años, si utilizaban asistencia para caminar y si tenían enfermedades previas (estadísticamente significativo). El 86% no tuvo dolor, el 91% estaba satisfecho y el 11% sufrió complicaciones. No hubo infecciones, ni cirugías de revisión. Conclusiones: Respetando las indicaciones y la técnica quirúrgica, las artroplastias totales de rodilla semiconstreñidas con constricción condilar varo-valgo logran buenos resultados a corto y mediano plazo, con una tasa baja de complicaciones, sin diferencias estadísticas en la función entre las cirugías primarias y de revisión.
