Published: November 2022

A rapid environmental assessment of the abandoned Palawan Quicksilver Mines, Inc. (PQMI) mined-out area and vicinities in Puerto Princesa City, Philippines was conducted from October 2018 to December 2019 to trace the pathways of mercury (Hg) concentration in different media, including groundwater. In this study, existing wells, drilled boreholes, and hand water pumps near the PQMI pit lake were used as sampling wells. Hg and other heavy metals – arsenic (As), barium (Ba), chromium (Cr), manganese (Mn), and nickel (Ni) – were analyzed to determine the concentrations and compared to the international and Philippine standard for drinking water. Results showed that As, Ba, and Hg concentrations in the entire groundwater samples collected from sampling wells have concentrations that are within the international and Philippines standards for drinking water. Groundwater samples from drilled boreholes have the measured Cr, Mn, and Ni concentrations exceed the standards for drinking water. The results further suggest that there is no mixing of groundwater and surface waters within the aquifer.
Cacao – Arbuscular Mycorrhizal Fungi Association: A Review on Its Increased Potential in Improving the Ecology of Cacao Plantations in the Philippines
Authors: Paguntalan Diana , Buot Inocencio , Aggangan Nelly
Published: November 2022

Cacao (Theobroma cacao) is both an economically and ecologically important crop worldwide especially in the Philippines, a tropical country suitable for its growth and cultivation. The association of this crop with arbuscular mycorrhizal fungi (AMF) is an understudied field but the benefits reported from this symbiosis highlights their irreplaceable role in enhancing growth conditions by facilitating the uptake of phosphorus, increasing yield through increased plant health and productivity, and in several ecological aspects such as soil biological dynamics and ecological processes that are carried out in cacao plant community. This paper proposed the different areas of improving cacao ecology that need to gain attention in the Philippines to augment the measures being undertaken to boost the country’s cacao plantations. This includes more research on areas of soil physicochemical properties, AMF genetic and functional diversity in cacao communities, and resistance to diseases of AMF-associated cacao trees. The ecology of the AMF-cacao association is an essential part of developing effective AMF inocula for the ultimate purpose of increasing the yield of cacao. Appropriate application of AMF could increase the overall yield of the country’s cacao plantations and can be translated to improving food security and many other economic gains.
On the bloch boundary conditions in sonic composites

Published: November 2022

A sonic composite is a finite size periodic array composed of scatterers embedded in a homogeneous material which has the unique property of exhibiting the band-gaps, where the sound is not allowed to propagate due to complete reflections. We propose in this paper an inverse problem to calculate the band structure of a sonic plate, based on evanescent Bloch boundary conditions between the scatterrers and the matrix, and the cnoidal superposition of waves. The sonic plate is composed of an array of acoustic scatterers embedded into an epoxy matrix. The scatterers are piezoceramic hollow spheres made from functionally graded materials with radial polarization, which support the Reddy and cosine laws. The proposed method requires the displacements registered at both sides of the plate. This allows the band structures to be determined experimentally. The Bloch boundary conditions greatly reduces the computational effort because they cancels the necessity to introduce non-reflecting boundary condition at the ends of the plate if sharp periodic boundary conditions between the scatterers and the matrix are used.

Kinematic analysis it is made, proving the ingenuity of the craftsman who has achieved a functional saw mill, whose advance motion is well correlated with the cutting motion. Different kinematic schemes and numerous charts are given, emphasizing the creativity of the craftsman, who empirically found the correct sizes for the mechanism’s elements
Achievement and expected issues in heat assisted magnetic recording
Authors:   University „Politehnica” of Bucharest, GAVRILĂ HORIA
Published: November 2022

The main goals in magnetic recording are the continuous increase of the areal recording density and the highest possible signal-to-noise ratio (SNR). The conventional magnetic recording has approached its physical limits. Further growth of the areal density is limited by the superparamagnetic effect and by the limited possibilities to further improve write heads design and pole materials in order to enhance the writing field. The perpendicular magnetic recording (PMR) with pole head and perpendicular media is the best alternative, especially to defer the superparamagnetic limit. PMR is also better situated to face the challenging design trilemma of magnetic recording: To increase the areal recording density, smaller grain volumes are needed, but to ensure the thermal stability of recorded information, the anisotropy should be increased accordingly; or, the increased anisotropy asks for higher writing fields, which are unavailable with the saturation magnetization of the magnetic materials of the current heads. Obviously, an alternative technology is needed to overcome the physical limit of conventional perpendicular recording (CPR). The most promising successor of CPR is the heat–assisted magnetic recording (HAMR), which is a multidisciplinary technology, a combination of magnetic and optical recording technology that proved experimentally areal densities of more than 1 Tb/in2 . HAMR allows the use of very smallgrain media, required for recording at ultra-high densities, with a larger magnetic anisotropy at room temperature, thus assuring a good thermal stability, while the local heating leads to a temporary magnetic softening of the medium. The realization of HAMR involved some challenges from both optical design and media properties. In the optical design the use of near-field transducers (NFT) represents an important advance. Regarding the media, a thermal design was used to produce the heating and cooling of the media within a very short time, about 1 ns, in order to achieve the desired data rate and generate a large thermal gradient for sharp bit edge definition. The structure of a HAMR system is briefly discussed, as well as the processes characterizing the writing process. A special attention is paid to the requirements for the materials needed for this type of recording: the granular L10-ordered FePt:X alloy sputtered on glass disk, the FePt-C and FePtC-Ag granular films and the bitpatterned media. Some important challenges of the HAMR technology are also summarized.
Optimization of hot-metal working of austenitic stainless steels
Authors:   University Politehnica Timisoara, Faculty of Engineering Hunedoara, ILCA IOAN
Published: November 2022

The present paper ends the series of industrial research performed by the author with regard to the heating optimization of the austenitic stainless ingots. Austenitic stainless steels possess the best thermal shock resistance properties at low temperatures and the best resistance to elevated temperatures, with versatile demands in the economy. For all stainless steel grades, the best hot workability is obtained when the structure of the steel at the hot-metal working temperature consists of a single phase. Small quantities of ferrite can be tolerated in the structure of the austenitic and martensitic steels as well as small quantities of austenite in the structure of ferritic steels, but these have to be maintained within certain limits, either through an appropriate change of the chemical composition of the steel, or through the control of the hot-metal working temperature. Therefore, the research observes the evolution of the structure during the heating of austenitic stainless steels, stating the soaking zone favourable for reducing the existing content of ferrite down to values that do not worsen the plasticity. Based on the conducted research, a new heating technology was designed, resulting in the reduction of the heating duration and a high efficiency in terms of the dissolution and spheroidization of the residual ferrite in the basic austenitic structure.

The critical state of structures simultaneous loaded with different loads is analised taking into account the principle of critical energy. The general case is considered when the material behavior is non-linear according to the power law. The critical state is correlated with the deterioration produced by cracks and with the residual stresses. General relationships have been deduced for the correlation of loads or stresses acting on a cracked structure having residual stresses. The theoretical relationships were verified against results reported in literature.

On 23 February 2009, the European Commission adopted a Communication on a Community approach on the prevention of natural and man-made disasters setting out an overall disaster prevention framework and proposing measures to minimize the impacts of disasters. All EU Member States were asked to develop national approaches and procedures to risk management including risk analyses, covering the potential major natural and manmade disasters, taking into account the future impact of climate change. Based on the European Commission guidelines, Romania is currently developing a national approach to risk assessment by taking into account nine major risk categories: floods, droughts, forest fires, earthquakes, mass displacement, Seveso industrial accidents, transport accidents involving hazardous materials, nuclear accidents, and epidemics/zoonoses. This paper will address the difficulties of hazard analyses and technological hazard mapping on a local, regional and national scale for all Seveso establishments. By using REHRA (Rapid Environment and Health Risk Assessment) as the basis for hazard analysis, all Seveso sites will receive a hazard index. By undergoing analysis for major physical effects, each site will go through a worst case scenario simulation of a major technological accident using modeling software. Using G.I.S. software, all spatial data collected from these establishments will be transferred to a WebGIS database. All spatial data will be expressed in a unitary standard according to the INSPIRE Directive which regulates natural risk zones. The resulting technological hazard map will be overlapped to the other hazard maps, thus creating a national hazard map and a starting point for the further national risk assessment
"Risk Factors Of Iron Deficiency Anaemia Among Children Admitted at Bossaso Hospital, Somalia "
Authors:   Nairobi University, Bashir Abdikani, Sadia , Adhiambo Andago Angela , Ngala Sophie
Published: November 2022

Anaemia is a condition where an individual has insufficient haemoglobin in the blood leading to inadequate supply of oxygen to body tissues. For children under five years, a haemoglobin level below 11.0 grams per decilitre of blood is considered anaemic. The main objective of this study was to determine the risk factors associated with iron deficiency anaemia in children aged 6 and 59 months in Bossaso, Somalia by conducting a cross-sectional study in Bossaso hospital. Mothers with children aged 6-59 months were selected purposively. Structured questionnaires were used to acquire information on socio demographic traits, morbidity and health status, sanitation practices, dietary habits and breastfeeding of the study population. Presence of anaemia in study children was determined through bio chemical test using Complete Blood Count (CBC). Chi-square, correlation and T-tests were used to relate the independent and dependent variables. The results show the study population had poor socio-economic status with high illiteracy levels. Most households relied on remittance for a monthly income which was insufficient to afford a diverse diet to improve their nutrition status. The results also indicate that iron deficiency anaemia was significantly associated with the mother/caregivers’ occupation (p=0.013), household income (p=0.007), child weight at birth (p=0.001) and the children’s DDS (p=0.012). These were therefore the main risk factors for iron-deficiency anaemia among study children. In conclusion, low child birth weight, poor dietary diversity and low household income are significant indicators contributing to the high prevalence of childhood anaemia. Interventions in health, education and agriculture that promote diversify their diets through growing iron rich foods such as spinach and beans in kitchen gardens as well as improved health are essential to reduce anaemia among these children. Keywords: Anaemia, iron deficiency, risk factors of anaemia, dietary intake, young children.

Published: November 2022

The study set out to determine maternal nutrition knowledge, infant feeding practices and nutritional status of the children aged 0-24 months in Bosaso District, Somalia. The cross sectional study used a semi structured questionnaire to interview 348 mothers with children 0-24 months of age living in Bosaso District, Somalia. Bosaso district was selected in convenience while mothers with children who met the inclusion criteria were selected randomly. The study used descriptive statistics. Chi-square and correlation used for analysis. Results obtained showed that mother’s nutrition knowledge on child feeding practices was moderate at 48.6%, poor knowledge at about 40.5% and highly knowledgeable at 11%. The percent of mothers knowledgeable in certain areas were 42.5%on exclusive breastfeeding, 31.6% on initiation of breastfeeding, 31% on frequency of breastfeeding and 42.5% of the mothers were exclusively breastfed infants 0-6months.There was a strong significant association between maternal nutrition knowledge and maternal education level (P< 0.01). There was no significant different between knowledge and mother/care giver’s marital status. There was significant correlation between maternal nutrition knowledge and breastfeeding practices (P <0.01). For all the three nutritional indicators, there was a positive correlation quite weak between Maternal nutrition knowledge and stunting (r=0.084), wasting (r=0.140), the strongest being underweight (r=0.167). There was a significant difference between maternal nutrition knowledge and underweight (P < 0.01) and wasting (P < 0.01). There was no significant different between maternal nutritional knowledge and stunting and MUAC. The mothers/care givers had moderate maternal nutrition knowledge on child Feeding practices. Most mothers and care givers were aware of the recommended breastfeeding practices but the actual practice of the recommended infant and young child feeding practices was poor. There is need for counseling among mothers and care givers on the recommended child feeding practices in order to reduce the level of malnourished children in the community.

Πιο συγκεκριμένα η μελέτη δεν αποσκοπεί σε μια προσπάθεια αναγνώρισης αντικειμενικών, αιτιολογικών παραγόντων της τοξικοεξάρτησης, αλλά επιχειρεί να καταδείξει πώς συμβάντα της διαδρομής του βίου υποκειμενοποιήθηκαν, διαμόρφωσαν τη δομή της προσωπικότητας των υπό μελέτη ατόμων και συνέβαλαν στην υιοθέτηση ενός «σχεδίου δράσης» προς την εξάρτηση από ψυχοτρόπες ουσίες. Πρόκειται δηλαδή για μια μελέτη της τοξικοεξαρτημένης προσωπικότητας. Σχεδιασμός: Η έρευνα αφορά εξαρτημένους από ψυχοτρόπες ουσίες που είναι σε φάση απεξάρτησης σε θεραπευτική κοινότητα. Επιλέχθηκε η βιογραφική προσέγγιση ως η καταλληλότερη μέθοδος, ενώ οι αφηγήσεις ζωής αποτέλεσαν το μεθοδολογικό εργαλείο της παρούσας έρευνας. Χώρος: Οι συνεντεύξεις πραγματοποιήθηκαν στη θεραπευτική κοινότητα του ΚΕΘΕΑ-Έξοδος στη Λάρισα. Ευρήματα: Η τοξικοεξάρτηση μοιάζει σαν ο καταλύτης μιας σειράς γεγονότων που δεν μπόρεσαν να συμβολοποιηθούν: γεγονότα όπως η απώλεια σημαντικών ανθρώπων, η μετανάστευση, οι πολλαπλές μετατοπίσεις και οι δύσκολες μεταβάσεις δεν μπόρεσαν να γίνουν αντικείμενα επεξεργασίας και παρέμειναν πλευρές ενός ψυχικού τραύματος που ενεργοποιείται και επικαιροποιείται μέσα από επαναλαμβανόμενες τραυματικές πράξεις. Σημαίνοντα ρόλο στις παραπάνω διαμεσολαβήσεις διαδραματίζει η οικογένεια. Κυρίαρχο δεδομένο στις οικογενειακές σχέσεις είναι η δυσλειτουργική διαγενεακή μεταφορά σχημάτων ζωής, οι μεταμορφώσεις των οποίων συντελούν στη διαγενεακή μεταβίβαση του ψυχικού τραύματος και οδηγούν στην εξάρτηση από ναρκωτικές ουσίες. Τέλος, στα ευρήματα καταγράφεται η πολιτισμική σύγκρουση που βιώνει το υποκείμενο-τοξικοεξαρτημένος στη μεταβατική φάση της εφηβείας, όπου και επιχειρεί να νοηματοδοτήσει τον κόσμο μέσα από την κουλτούρα της χρήσης ναρκωτικών ουσιών. Συμπεράσματα: Στα συμπεράσματα καταγράφεται το πώς μορφοποιούνται στην υποκειμενική συνείδηση των φορέων των βιογραφιών τα κυρίαρχα βιογραφικά στοιχεία της διαδρομής του βίου τους. Η σχέση του υποκειμένου με όλα αυτά τα στοιχεία είναι δυναμική και συστήνει έναν αγώνα, ο οποίος παρά την «ήττα» του υποκειμένου είναι παρών. Οι νέες μορφοποιήσεις αναδύονται κάτω από μια παροντική οπτική, η οποία διαμεσολαβείται από την αφηγηματική διαδικασία. Το παρόν της αφήγησης τοποθετείται στο ευρύτερο θεραπευτικό περιβάλλον και επιχειρεί νέες νοηματοδοτήσεις των δεδομένων της ύπαρξης των υποκειμένων.

The Czech 2021 General Election and its Impact on the Party System
Authors: Havlík Vlastimil , Lysek Jakub
Published: November 2022

The article analyses the results of the 2021 general election in the Czech Republic. The election was shaped by two major factors. First, it took place in the shadow of the Covid pandemic crisis. Second, the Czech Republic was governed by a cabinet dominated by a populist political party with unprecedented support from the communist party for most of the term. The major feature of the election campaign was the formation and eventual victory of two anti-populist coalitions. The results brought about a decrease in electoral volatility and fragmentation of the party system. However, the formation of ideologically diverse coalitions is a challenge to the increased stability of the party politics. Moreover, the electoral loss of two traditional leftist parties (the Communists and the Social Democrats) is a major change in the logic of party competition. The populist/anti-populist logic of the campaign undermined the discursive salience of left-right issues and suppressed the usual policy-based competition. Nevertheless, analysis of the electorate shows the dominant role of policy issues in the voters’ decision making.

Ultrasonic detection is an effective method to quantify bubbles in opaque liquid, and acoustic scattering model is the key in ultrasonic inversion technique. Classical scattering models are usually based on the spherical assumption, and ka is much less than 1. However, these conditions are not always satisfied in practical applications. In this study, a quantitative strategy of ultrasonic inversion is proposed for non-spherical bubbles and ka deviation assumption. A series of solution models for a spherical gas bubble is established without considering the ka constraint, and it is compared with the classical Medwin (\begin{document}$ka\ll1 $\end{document}) and Anderson (ka ≈ 1) models. The difference in scattering cross section σbs betweem them is only at the higher order formants of scattering, so the fitted line can be used to solve the multi-valued problem between σbs and ka. For a non-spherical bubble, σbs is determined by the frequency domain backscattering signal, the size is characterized by the equivalent radius a*, and the inversion is performed by fitted curve from series solution model. Ultrasonic quantitative results are examined by high-speed photography. Results show that during the bubbles rising along a zigzag path, they develop non-spherical bubbles, their scattering cross sections are measured by the frequency domain scattering signal obtained at a position of ultrasonic measurement, and the equivalent radius is inverted by the series solution fitting curve. The deviation of the result from the actual result r0 is about 1mm (relative error less than 45%) when 9≤kr0≤35. This method can be used for implementing the acoustic inversion of non-spherical bubbles in a certain range of measurement accuracy.

The first comprehensive introduction to the origins, aspirations, and evolution of live coding.

Performative, improvised, on the fly: live coding is about how people interact with the world and each other via code. In the last few decades, live coding has emerged as a dynamic creative practice, gaining attention across cultural and technical fields—from music and the visual arts to computer science. Live Coding: A User's Manual is the first comprehensive introduction to the practice and a broader cultural commentary on the potential for live coding to open up deeper questions about contemporary cultural production and computational culture. This multiauthored book—by artists and musicians, software designers, and researchers—provides a practice-focused account of the origins, aspirations, and evolution of live coding, including expositions from a wide range of live coding practitioners. In a more conceptual register, the authors consider liveness, temporality, and knowledge in relation to live coding, alongside speculating on the practice's future forms.

Art for Coexistence
Authors: Ross Christine
Published: November 2022

An exploration of how contemporary art reframes and humanizes migration, calling for coexistence—the recognition of the interdependence of beings.

In Art for Coexistence, art historian Christine Ross examines contemporary art's response to migration, showing that art invites us to abandon our preconceptions about the current “crisis”—to unlearn them—and to see migration more critically, more disobediently. Viewers in Europe and North America must come to see migration in terms of coexistence: the interdependence of beings. The artworks explored by Ross reveal, contest, rethink, delink, and relink more reciprocally the interdependencies shaping migration today—connecting citizens-on-the-move from some of the poorest countries and acknowledged citizens of some of the wealthiest countries and democracies worldwide.

Alejandro González Iñárritu, Laura Waddington, Tania Bruguera, and others, demonstrate art's power to mediate experiences of migration. Ross argues that art invents a set of interconnected calls for more mutual forms of coexistence: to historicize, to become responsible, to empathize, and to story-tell. Art history, Ross tells us, must discard the legacy of imperialist museology—which dissocializes, dehistoricizes, and depoliticizes art. It must reinvent itself, engaging with political philosophy; postcolonial, decolonial, Black, and Indigenous studies; and critical refugee and migrant studies.

If you are reading this, you have done something that only our species has evolved to do. You have acquired a natural language. This book asks, How has this changed us?

Where scholars have long wondered what it is about humans that makes language possible, N. J. Enfield and Jack Sidnell ask instead, What is it about humans that is made possible by language? In Consequences of Language, their objective is to understand what modern language really is and to identify its logical and conceptual consequences for social life. Central to this undertaking is the concept of intersubjectivity, the open sharing of subjective experience. There is, Enfield and Sidnell contend, a uniquely human form of intersubjectivity, and it is essentially intertwined with language in two ways: a primary form of intersubjectivity was necessary for language to have begun evolving in our species in the first place and then language, through its defining reflexive properties, transformed the nature of our intersubjectivity. In the authors' analysis, social accountability—the bedrock of society—is grounded in this linguistically transformed, enhanced kind of intersubjectivity.

The account of the language-mind-society connection put forward in Consequences of Language is one of unprecedented reach, suggesting new connections across disciplines centrally concerned with language—from anthropology and philosophy to sociology and cognitive science—and among those who would understand the foundational role of language in making us human.
Whole brain correlates of individual differences in skin conductance responses during discriminative fear conditioning to social cues

Understanding the neural basis for individual differences in the skin conductance response (SCR) during discriminative fear conditioning may inform on our understanding of autonomic regulation in fear-related psychopathology. Previous region-of-interest (ROI) analyses have implicated the amygdala in regulating conditioned SCR, but whole brain analyses are lacking. This study examined correlations between individual differences in SCR during discriminative fear conditioning to social stimuli and neural activity throughout the brain, by using data from a large functional magnetic resonance imaging study of twins (N= 285 individuals). Results show that conditioned SCR correlates with activity in the dorsal anterior cingulate cortex/anterior midcingulate cortex, anterior insula, bilateral temporoparietal junction, right frontal operculum, bilateral dorsal premotor cortex, right superior parietal lobe, and midbrain. A ROI analysis additionally showed a positive correlation between amygdala activity and conditioned SCR in line with previous reports. We suggest that the observed whole brain correlates of SCR belong to a large-scale midcingulo-insular network related to salience detection and autonomic-interoceptive processing. Altered activity within this network may underlie individual differences in conditioned SCR and autonomic aspects of psychopathology.

Non-structural protein 1 (Nsp1) is a main pathogenicity factor of α- and β-coronaviruses. Nsp1 of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) suppresses the host gene expression by sterically blocking 40S host ribosomal subunits and promoting host mRNA degradation. This mechanism leads to the downregulation of the translation-mediated innate immune response in host cells, ultimately mediating the observed immune evasion capabilities of SARS-CoV-2. Here, by combining extensive molecular dynamics simulations, fragment screening and crystallography, we reveal druggable pockets in Nsp1. Structural and computational solvent mapping analyses indicate the partial crypticity of these newly discovered and druggable binding sites. The results of fragment-based screening via X-ray crystallography confirm the druggability of the major pocket of Nsp1. Finally, we show how the targeting of this pocket could disrupt the Nsp1-mRNA complex and open a novel avenue to design new inhibitors for other Nsp1s present in homologous β-coronaviruses.

“Double whammy”: a rapid review of rural vs urban psychosocial cancer experiences and telehealth service in five countries during the COVID-19 pandemic
Authors: Barnes Marisa , Rice Kylie , Murray Clara , Thorsteinsson Einar
Published: November 2022

Background

Cancer is a long-term condition with biopsychosocial components. People with cancer living in rural areas can have poorer treatment outcomes and higher rates of unmet psychosocial needs than those in urban areas. Cancer, as opposed to other chronic conditions, poses a unique challenge in this current COVID-19 pandemic context, given immunocompromised states of patients and long-term survivor treatment effects. The disaggregated impact of psychosocial issues potentiated by the pandemic on rural vs. urban cancer populations is yet to be quantified. This rapid review investigates whether (i) people with cancer are experiencing pandemic-related psychosocial impacts, (ii) these impacts are equivalent in urban and rural locations, and (iii) whether the rapid uptake of telehealth mitigates or reinforces any identified impacts.

Method

A rapid review was conducted for literature published between December 2019 and 13 August 2021.

Results

Fifteen papers were included, incorporating evidence from five countries. The available literature suggests people affected by cancer living in rural areas are evidencing disproportionate psychosocial impacts of COVID-19, compounding cancer experiences. Despite its widespread and necessary use during the pandemic, telehealth was identified as an additional challenge for rural people with cancer.

Conclusions

Clinicians working with rural people affected by cancer should ensure recognition of the greater risks of psychosocial concerns in their rural patients, and reduced access to health services. Whilst telehealth and other remote technologies are useful and necessary in this pandemic era, clinicians should consider whether its use benefits their rural clients or reinforces existing disparities.
The effects of Saccharomyces boulardii on rat colonic hypermotility induced by repeated water avoidance stress and the potential mechanism

Background

Saccharomyces boulardii (Sb) has been reported to have the potential to regulate gut motility. The aim of this experiment was to explore the possible function of Sb in gut hypermotility elicited by repeated water avoidance stress (WAS).

Methods

Adult male Wistar rats (N = 24) were divided into one of the following three groups: control (C), NS (normal saline) + WAS group (N), and Sb + WAS group (S). A diarrhea-predominant irritable bowel syndrome (IBS-D) model in rats was induced using the WAS method. Gut motility was evaluated by stool pellet expulsion per hour. The contractile activity of the colonic muscle strips was measured using an RM6240 multichannel physiological signal instrument. qRT-PCR and immunohistochemistry were used to assess Toll-like receptor 4 (TLR4) expression in colon tissue. ELISA was used to measure the level of cytokines in the serum and colonic tissue. Also, the microbiota composition was determined using high-throughput 16S rRNA sequencing.

Result

The results showed that oral Sb decreased the WAS-induced increased defecation and colonic hypermotility in vivo. Furthermore, Sb also decreased the contractile amplitude of colonic circular muscle (CM) and longitudinal muscle (LM) strips in a dose-dependent manner in vitro. Repeated WAS increased TLR4 expression, but Sb reversed it. Sb also reduced interleukin-6 (IL-6), IL-1β, and interferon-γ (IFN-γ) levels in serum and colonic tissue, while increasing IL-10 levels in colonic tissue. Meanwhile, the rats from the NS + WAS group had decreased microbiota diversity and had lower relative abundances of Patescibacteria, Epsilonbacteraeota, Cyanobacteria, and Turicibacter compared with controls. The rats in the Sb + WAS group showed a tendency to increase the relative abundance of Blautia when compared to control rats and had lower relative abundances of Acidobacteria and Anaerostipes compared with the NS + WAS group.

Conclusion

Our findings demonstrated that Sb improved colonic hypermotility in rats, reversed the high-expression of TLR4 in the colon caused by repeated WAS, modulated cytokines in the colon and serum, and altered the gut microbiota, indicating that Sb may be useful for IBS-D.
Para una edición de la Historia general del reino de Chile, Flandes Indiano (1674), de Diego de Rosales. Notas bien sueltas

La edición y anotación de la Historia general del reino de Chile, Flandes Indiano (1674), del jesuita Diego de Rosales, plantea enormes desafíos para el investigador. A su gran extensión, que alcanza los 840 folios distribuidos en diez libros, se suma una historia editorial azarosa del manuscrito y la multiplicidad de temas que aborda la crónica: además de ser una relación minuciosa de la historia de Chile a lo largo de los siglos XVI y XVII, esta incluye un repertorio de viajes magallánicos, un tratado etnográfico y un completo tratado natural del territorio. Asimismo, el texto incorpora más de 6600 apostillas marginales que hay que desentrañar. La singular erudición de que hace gala el autor, acompañada de su larga experiencia personal acerca de lo que escribe, hacen que el editor tenga que realizar importantes esfuerzos para un correcto desciframiento e interpretación del texto.
El virus de la parisitis en tres novelas chilenas: un viaje al ideal de Baudelaire
Authors:   Pontificia Universidad Católica de Chile (Chile), Folch Francisca
Published: November 2022

El mundo de placer ofrecido por la Belle Époque europea, como se la imaginaba la elite latinoamericana, creó una visión romántica de París que chocaba con el ennui del país nativo. Este conflicto puede compararse productivamente con la tensión entre ideal y spleen explorado décadas antes por Baudelaire en Las flores del mal (1857). Un ejemplo chileno de este fenómeno aparece en dos novelas chilenas emblemáticas, Los trasplantados (1904) de Alberto Blest Gana y Criollos en París (1933) de Joaquín Edwards Bello, que muestra personajes infectados por la parisitis, una adicción a los placeres corruptos de la ciudad. La novela de Edwards Bello incluye al personaje de Jorge Dueñas, un retrato apenas disimulado del extraordinario personaje de sociedad Jorge Cuevas, quien, en su novela corta El amigo Jacques (1912), basa a su vez su personaje principal en su amigo Edwards Bello y contribuye una respuesta similarmente ambivalente a la construcción de una identidad latinoamericana moderna.
Peer Counsellor Training for Sex Workers: A Pilot Program in Lekwungen Territory (Victoria, BC)
Authors: Reeves Allison , Saunders Kathryn , Phillips Rachel

Sex workers face significant stigma when accessing mental health services, due to the history of criminalization of sex work and the resulting negative biases in the healthcare sector. Peers Victoria Resources Society is a sex worker advocacy organization who partnered with the researchers to develop and implement a pilot program on peer-counsellor skills development for sex workers incorporating trauma informed practice. The course sought to build on leadership, capacity and strengthen solidarity while acknowledging societal stigma, in hopes that this pilot could result in supplementary care to mainstream mental health services for this underserved community. Interviews were conducted with eight participants prior to and following the 10-week course. Participants reported increased competency in basic counselling skills such as reflective listening, and all noted the applicability of these skills in their personal and working lives. Suggestions were made to scaffold future course content to manage both academic and emotional learning.
