Antiquities in exile: Ottoman Greek refugees’ trauma and Ionian antiquities
Authors: Papatheodorou Artemis 
Published: April 2024

AbstractThis article contributes to our understanding of the links between forced exile, refugee trauma, and antiquities. It zooms in to the case of the Ottoman Greek refugees who fled to Greece in the wake of the collapse of the Ottoman Empire and the defeat of the Greek army by the Turkish National Movement forces in 1922. It critically discusses memories of ordinary people from Lithri (ancient Erythrai, modern-day Ildırı), Nymphaio (near ancient Sardeis, modern-day Kemalpaşa), and Ayasolouk (ancient Ephesus, modern-day Selçuk). It also looks at aspects of the literary world of Smyrna-born poet and Nobel Laureate George Seferis. It is argued that, for these refugees, antiquities served as conduits, symbols, metaphors, and allegories for expressing the trauma linked to their state of uprootedness and forced exile. The refugees in question employed reverse “rescue archaeologies,” where it was for antiquities to salvage refugees rather than the other way round. The main primary material consulted consists of refugee testimonies from the Oral Tradition Archive of the Centre for Asia Minor Studies and Seferis’s diary. The approach is interdisciplinary and, besides Ottoman Greek history, draws on cultural geography, anthropology, archaeology as well as broader discussions in memory studies and critical heritage studies.
Latest Pleistocene glacial chronology and paleoclimate reconstruction for the East River watershed, Colorado, USA

Published: April 2024

AbstractReconstructing Pleistocene glaciation timing and extent is vital for understanding paleoclimate. Whereas late Pleistocene glaciation has been studied extensively in western North American mountain ranges, the glacial history of the western Elk Range in Colorado remains understudied, particularly in the East River watershed, a site of intense scientific focus. Here we use cosmogenic nuclide exposure and depth–profile dating methods to determine the timing of glaciation in the East River watershed. We use glacier modeling to reconstruct paleoglacier extents and quantify past climate conditions. Our findings indicate that the East River glacier retreated from its maximum position approximately 17–18 ka, moving to recessional positions between 13 and 15 ka, before experiencing more substantial retreat to high-elevation cirques around 13 ka. Glacier modeling suggests that the maximum ice extents at 17–18 ka could have been sustained by temperature depressions of approximately −6.5°C compared to modern conditions, assuming consistent precipitation. Additionally, the ice position at 13–15 ka could have been supported by temperature depressions of around −4.0°C. These results offer insights into the deglaciation timeline in the East River watershed and broader western Elk Range as well as paleoclimate conditions during the late Pleistocene, which may aid future research on critical zone evolution in the East River watershed.

AbstractThe ultrastructure and cytochemistry of the glycocalyx of the tegument of Opisthorchis viverrini during maturation from newly excysted juvenile to adult stages were investigated using colloidal iron, ruthenium red and lectin stainings. The results showed that the glycocalyx was intensely stained by the first two dyes, thus indicating the presence of relatively high amounts of negative charges. However, the thickness and intensity of the staining decreased during the fluke's maturation. Binding studies using lectin probes on the surface of adult parasites showed that binding sites for Canavaliaensiformis (Con A), Triticum vulgaris (WGA) and Ricinus communis I(RCA I) were present in relative large amounts on the glycocalyx of the adult tegument, whereas those for Dolichos biflorus (DBA) were relatively fewer in number, and those for Ulex europaeus I (UEA I) were absent. The binding patterns of Con A, WGA, RCA I and DBA were generally similar, and the reaction product was uniformly distributed over the dorsal and ventral surfaces of the parasite's body. These bindings, therefore, indicate the presence of D-mannose/D-glucose, N-acetyl-D-glucosamine/sialic acid, D-galactose and N-acetyl-D-galactosamine residues on the glycocalyx of the adult tegument.
Ultrastructural study of spermiogenesis and the spermatozoon in Catenotaenia pusilla, an intestinal parasite of Mus musculus
Authors: Hidalgo C. , Miquel J. , Torres J. , Marchand B. 
Published: April 2024

AbstractThe ultrastructure of spermiogenesis and the mature spermatozoon in Catenotaenia pusilla (Cestoda: Catenotaeniidae) is described. Spermiogenesis is characterized by the presence of a single axoneme which grows on the outside of a cytoplasmic extension at an angle of 45°. Flagellar rotation and proximodistal fusion are produced in this process. The centrioles lack striated roots and an intercentriolar body. In the mature spermatozoon four different regions are described. The anterior extremity is capped by an apical cone and presents two helical crest-like bodies of unequal length. The axoneme, of the 9 + ‘1’ pattern of the Trepaxonemata, presents a periaxonemal sheath. The cortical microtubules form a spiral pattern at an angle of about 40° to the hypothetical spermatozoon axis. The nucleus is kidney- to horseshoe-shaped in cross section. Granules and proteinaceus walls are not observed in the spermatozoon of C. pusilla.

Published: April 2024

AbstractThe karyotype of glirid tapeworm Rodentolepismyoxi (Rudolphi, 1819) (Cestoda: Hymenolepididae) comprises six pairs of small bi-armed chromosomes (2n = 12). All pairs of chromosomes possess uniform morphology, i.e. metacentric, submetacentric or meta-submetacentric types of structures. The formula of the karyotype structure is n = 2m + 1m-sm + 3sm. The absolute chromosome length ranges from 3.78 to 2.00 μm. The mean total length of the haploid complement is 15.98 μm. The first pair (group A) is the largest, pairs 2 and 3 can be grouped into group B while pairs 4–6 are smaller and can be classified as group C. The number of chromosomes of R. myoxi is the same for the congeneric species, however, karyological characteristics differ from all recently known karyotypes of rodent hymenolepidids.
Strongyloides ratti: chemotactic responses of third-stage larvae to selected serum proteins and albumins
Authors: Koga M. , Tada I. 
Published: April 2024

AbstractExperiments were carried out in vitro to investigate whether the sera of several animals as well as albumins and peptides might act as attractants for larvae of Strongyloidesratti. Samples of sera from several mammal species were dialysed and the aliquots were further centrifuged using ultrafiltration cartridges to remove any remaining small molecules. Additional test substances included commercially obtained ovalbumin, rat and bovine serum albumins, polypeptides such as peptone, tryptone and tryptose, amino nitrogens, monosaccharides, and reduced glutathione (triaminopeptide). Larvae were strongly attracted to the dialysed mammalian sera, which mainly consisted of serum albumin and globulins. Ov- and serum albumins, and polypeptides also acted as attractants. On the other hand, reduced glutathione, 16 kinds of amino acids and four kinds of monosaccharides did not attract this nematode.

Published: April 2024

AbstractThe excretory/secretory (ES) metabolic products released by Gastrothylax crumenifer (Trematoda: Digenea) during in vitro incubations and the somatic extract of the adult parasite were analysed using polyacrylamide gel electrophoresis (PAGE). Immunogenicity of ES and somatic extracts were evaluated by immunoblotting and ELISA using sera raised against ES and somatic antigens in rabbits. The electropherograms of ES and somatic extracts have been resolved into 38 and 41 polypeptides, respectively. The apparent molecular weights of these polypeptides range from < 29 to > 205 kDa. A total of 14 polypeptides were found to be common to both of the samples. The analysis of immunoblot results revealed 22 and 27 antigenic polypeptides in ES and somatic extracts respectively. Only 11 and 13 antigenic polypeptides were found specific to ES and tissue extract respectively. The molecular weights of these specific polypeptides were calculated to be < 14.4, 16, 20, 25, 33, 42, 119, 125 and > 205 kDa for metabolic products and < 14.4, 25, 30, 35, 78, 84 and > 205 kDa for the tissue extracts, respectively. Analysis of ELISA results revealed that a dilution of up to 1:3200 of the test sera could react with the ES product. Further, when the ES antigens were allowed to react with antisomatic extracts in hyperimmune sera the titre of IgG increased up to a dilution of 1:12800. The potential importance of these antigens in the immunodiagnosis of amphistomiasis is discussed.
Genetic diversity among isolates of Trichinella spiralis from the Province of Buenos Aires, Argentina

Published: April 2024

AbstractRandom Amplified Polymorphic DNAs, (RAPDs) are used to study the occurrence of Trichinella britovi and T5 among domestic animals in the Province of Buenos Aires, Argentina and to assess the genetic diversity among isolates of T. spiralisfrom this area in a number of infected hosts. All the local isolates proved to be T. spiralis. Six of the eight primers used indicate that the Buenos Aires isolates are distinct from each other as they produce a considerable number of polymorphic bands. Our overall estimates are relatively higher than other intraspecific distances previously estimated within species of this genus and among T. spiralis isolates. Such high degrees of variability observed among local isolates and between isolates from Buenos Aires and Spain should be taken into account when defining isolates within this species, and considering differences in the epidemiology of T. spiralis.
Acquisition of parasites correlated with social rank and behavioural changes in a fish species
Authors: Bartoli P. , Morand S. , Riutort J.-J. , Combes C. 
Published: April 2024

AbstractA survey of parasites was conducted on 258 Symphodus ocellatus (Teleostei: Labridae) collected in Corsica National Park (west Mediterranean). In addition, the total length, sex and social status were recorded for each individual fish. Three species of trematodes were found in the digestive tract. One of the parasites, Genitocotyle mediterranea, was only present, with one exception, in males of large size, and principally in the individuals that had the highest status and that were involved in nest construction. Two hypotheses are suggested to explain this particular distribution of a parasite: the immunocompetence handicap and the changing trophic behaviour as the fish grows.
Larval anisakids parasitizing the blue whiting, Micromesistius poutassou, from Motril Bay in the Mediterranean region of southern Spain

Published: April 2024

AbstractA total of 301 blue whiting, Micromesistius poutassou Risso, 1826, ranging in length from 17 to 28 cm, from Motril Bay (Mediterranean coast, south Spain) were examined for anisakid nematodes, as these fish are common items in the Spanish Mediterranean diet. Three anisakid species were morphologically identified with a total prevalence of 10.63%. Anisakis simplex s.l. Rudolphi, 1809 had a prevalence value of 6.65%, compared with 2.66% for A. physeteris Baylis, 1923 and 2.33% for Hysterothylacium aduncum Rudolphi, 1802. Variations in prevalence values with season and host size are discussed. Allozyme markers (leucine aminopeptidase-1) were used to identify anisakid nematodes assigned to the A. simplex complex and all examined larvae were found to correspond genetically to A. pegreffii Nascetti et al., 1986.
The spectre of Ma Phyu? Loyalty, competence, and the spatial dynamics of imperial administration in colonial Burma
Authors: Ren Chao 
Published: April 2024

AbstractThis article explores the spatial dynamics of imperial administration in colonial Burma through the lens of gender, bureaucracy, and frontier. Focusing on the story of Hugh Ernest McColl, a British administrative officer in Burma who struggled for promotion as a result of his marriage to a Burmese woman, the article sheds light on the spatial dynamics regarding loyalty, competence, and political priorities in the imperial administration of frontiers. Such spatial dynamics were most clearly manifested in the diverging attitudes between central authorities and local governments towards McColl’s case. Drawing on archival sources and secondary literature that contextualize McColl’s case within the broader textures of colonial governance, this article argues that McColl’s case reveals the internal contradiction of the imperial administration, which saw a constant tension between the ideological imperatives of control and the practical demands of how to control. McColl’s story is therefore a story of broader significance—of the inherent structural contradiction of colonial rule and its inability to overcome it.
Missing millions: Java’s 1944–45 famine in Indonesia’s historiography
Authors: van der Eng Pierre 
Published: April 2024

AbstractThis article asks why the victims of the 1944–45 famine in Indonesia’s main island of Java are largely missing from Indonesia’s public memory and historiography. It surveys relevant studies, to conclude that there is no consensus on the human toll of the famine. The article then traces the origins of an initial estimate of four million mentioned by Indonesia’s authorities to data on mortality and births uncovered in late 1945. It discusses the outcomes of a recent study that analysed these data to re-estimate excess deaths of, respectively, 0.7 and 1.2 million during 1944 and 1945. The difference with the initial estimate is that it also included unborn children and an unsubstantiated approximation of victims in 1946. The article analyses the likely reasons why the millions of victims of the famine went missing from Indonesia’s public memory and historiography during the 1950s and 1960s.

Abstract
Rectal swabs of 104 patients who underwent abdominal surgery were screened for ESBL producers. Sequence types (STs) and resistance genes were identified by whole-genome sequencing of 46 isolates from 17 patients. All but seven isolates were assigned to recognized STs. While 18 ESBL-producing E. coli (EPEC) strains were of unique STs, ESBL-producing K. pneumoniae (EPKP) strains were mainly ST14 or ST15. Eight patients harboured strains of the same ST before and after abdominal surgery. The most prevalent resistant genes in E. coli were blaEC (69.57%), blaCTX-M (65.22%), and blaTEM (36.95%), while blaSHV was present in only K. pneumoniae (41.30%). Overall, genes encoding β-lactamases of classes A (blaCTX-M, blaTEM, blaZ), C (blaSHV, blaMIR, and blaDHA), and D (blaOXA) were identified, the most prevalent variants being blaCTX-M-15, blaTEM-1B, blaSHV-28, and blaOXA-1. Interestingly, blaCMY-2, the most common pAmpC β-lactamase genes reported worldwide, and mobile colistin resistance genes, mcr-10-1, were also identified. The presence of blaCMY-2 and mcr-10-1 is concerning as they may constitute a potentially high risk of pan-resistant post-surgical infections. It is imperative that healthcare professionals monitor intra-abdominal surgical site infections rigorously to prevent transmission of faecal ESBL carriage in high-risk patients.

Published: April 2024

AbstractHeart University [https://www.heartuniversity.org/] is a free educational website providing structured training curricula with knowledge-based testing and access to webinars and conference recordings for practicing and in-training providers of paediatric and congenital cardiac care. To date, there are over 15,000 registered website users from over 140 countries on Heart University, with over 2,000 training modules and/or recorded educational videos. Heart University has developed an “asynchronous” educational lecture series entitled “Pediatric and Congenital Cardiac Care in Resource-Limited Settings.” This recorded lecture series is specifically focused on topics relevant to practicing paediatric and/or congenital cardiac care in low-resource settings.A relatively new initiative, “Cardiology Across Continents,” supplements the existing educational resources for providers of paediatric and/or congenital cardiac care in low-income countries and lower-middle-income countries by providing an additional live, interactive, case-based forum. Sessions occur every 1–2 months and focus on challenging cases from diagnostic or management perspective with a view to promote collaboration between partnered institutions. “Cardiology Across Continents” is an expanding initiative that facilitates learning and collaboration between clinicians across varied practice settings via interactive case discussions. We welcome trainees and providers of paediatric and congenital cardiac care to join the sessions and invite any insight that can enhance learning for clinicians around the world. This manuscript describes “Cardiology Across Continents” and discusses the development, history, current status, and future plans of Heart University.
Developing a Critical Understanding of Environmental Activism through Active Learning
Authors: Moulton Jeremy F. G. 
Published: April 2024

ABSTRACTThis article presents a short simulation active-learning exercise that can be used in political science undergraduate and postgraduate environmental politics courses to introduce and teach the subject of environmental activism. The exercise, which asks students to role play as determined environmental activists, draws on an analytical framework from Diani and Donati (1999) that provides a typology of nonpartisan political organizations. This “learning through typology” allows students to prioritize critical analysis while engaging with the subject matter in a creative and enjoyable way. The article provides the full process of the exercise, from the grounding in the framework and provision of contextual examples, to the running of the simulation, and finally to the presentation of students’ work and a group debriefing session. This exercise therefore adds to the growing use of simulations and active learning in the increasingly prominent field of environmental politics.
The Global Distribution of Grazing Dynamics Estimated From Inverse Modeling
Authors: Rohr Tyler , Richardson Anthony , Lenton Andrew , Chamberlain Matthew A. , Shadwick Elizabeth H. 
Published: April 2024

AbstractGrazing dynamics are one of the most poorly constrained components of the marine carbon cycle. We use inverse modeling to infer the distribution of community‐integrated zooplankton grazing dynamics based on the ability of different grazing formulations to recreate the satellite‐observed seasonal cycle in phytoplankton biomass after controlling for physical and bottom‐up controls. We find large spatial variability in the optimal community‐integrated half saturation concentration for grazing (K1/2), with lower (higher) values required in more oligotrophic (eutrophic) biomes. This leads to a strong sigmoidal relationship between observed mean‐annual phytoplankton biomass and the optimally inferred grazing parameterization. This relationship can be used to help constrain, validate and/or parameterize next‐generation biogeochemical models.
The Combined Effects of Ocean Acidification and Respiration on Habitat Suitability for Marine Calcifiers Along the West Coast of North America

Published: April 2024

AbstractThe California Current Ecosystem (CCE) is a natural laboratory for studying the chemical and ecological impacts of ocean acidification. Biogeochemical variability in the region is due primarily to wind‐driven near‐shore upwelling of cold waters that are rich in re‐mineralized carbon and poor in oxygen. The coastal regions are exposed to surface waters with increasing concentrations of anthropogenic CO2 (Canth) from exchanges with the atmosphere and the shoreward transport and mixing of upwelled water. The upwelling drives intense cycling of organic matter that is created through photosynthesis in the surface ocean and degraded through biological respiration in subsurface habitats. We used an extended multiple linear‐regression approach to determine the spatial and temporal concentrations of Canth and respired carbon (Cbio) in the CCE based on cruise data from 2007, 2011, 2012, 2013, 2016, and 2021. Over the region, the Canth accumulation rate increased from 0.8 ± 0.1 μmol kg−1 yr−1 in the northern latitudes to 1.1 ± 0.1 μmol kg−1 yr−1 further south. The rates decreased to values of about ∼0.3 μmol kg−1 yr−1 at depths near 300 m. These accumulation rates at the surface correspond to total pH decreases that averaged about 0.002 yr‐1; whereas, decreases in aragonite saturation state ranged from 0.006 to 0.011 yr‐1. The impact of the Canth uptake was to decrease the amount of oxygen consumption required to cross critical biological thresholds (i.e., calcification, dissolution) for marine calcifiers and are significantly lower in the recent cruises than in the pre‐industrial period because of the addition of Canth.
