Augments and reinforcing constructs made of titanium with a porous coating have been used for bone defect management in addition to osteoplastic materials. Additive technologies in traumatology and orthopedics for extensive defects in bones and joints have been applied when it is impossible to use standard designs. The purpose of the study was to evaluate short-term results and perspectives of using additive technologies for bone defects after failed joint arthroplasties and osteosynthesis. Materials and methods In 2018 to November 2019, seven patients with lower extremity bone defects underwent treatment at the Department of Traumatology and Orthopedics of the Moscow Regional Research and Clinical Institute with custom-made implants fabricated with additive technologies. The operations were carefully planned using CT scans, 3D modeling, and implant printing. Particular attention was paid to clean the implant from residual metal powder. Patients were distributed depending on the type of defect and the operation performed (arthroplasty, revision arthroplasty). Results The short-term results of using customized implants were analyzed in this study. The average Harris hip score before surgery was 37.8 points, and after the surgery it was 80.2 points. Pain after surgery in all patients was also evaluated by Harris scale and was 37.1 points; the functionality of patients after surgery was 38.4 points. The custom-made designs have a number of distinguishing advantages against the standard ones. A customized anatomical design provides easier fixation; ergonomic design allows implant retention without removing metal fixators if exist; there is less soft tissue injury during surgery (allinside principle); and convenient bone grafting around the implant. Conclusions The use of additive technologies for bone defects improves the functional results and life quality of the patient. At the moment, practical application of 3D designs has a number of limitations in financial and legal support in practical health care. Further implementation of additive technologies in traumatology and orthopedics will be supported by the grant from the President of the Russian Federation.

Introduction The paper presents a comparative analysis of one-stage treatment of chronic osteomyelitis using tobramycin-impregnated calcium sulfate and β-tricalcium phosphate mixed with antibiotics impregnated hydroxyapatite to fill in the cavitary defect of long bones. Material and methods The retrospective group (group 1, n = 34) was treated with tobramycin-impregnated calcium sulfate (Osteoset T), and the prospective group (group 2, n = 25) received β-tricalcium phosphate mixed with antibiotics impregnated hydroxyapatite (ReproBone). Results and discussion There were no significant differences between the groups of patients by gender, age, type of osteomyelitis and duration of the disease. The differences in the operating time, intraoperative blood loss and the size of the cavitary bone defect post debridement were not significant between the groups. There were no significant differences in preoperative level of CRP between the groups, with CRP being higher (p = 0.02) in group 1 than in group 2, prior to the discharge from the hospital. Recurrence was seen in 35 % (n = 12) of group 1 and in 16 % (n = 4) of group 2 at a 21/2-year follow-up. The risk of recurrence was found to be 2.2 times greater with use of commercially available biocomposite loaded with tobramycin that that with β-tricalcium phosphate mixed with hydroxyapatite (HR 2.206; CI 0.806-6.038) impregnated with antibiotics administered with preoperative microbiological findings. Conclusion Combined β-tricalcium phosphate based biocomposites mixed with hydroxyapatite impregnated with broad-spectrum antibiotics showed greater efficacy for methicillin-resistant staphylococcus aureus in the treatment of chronic osteomyelitis filling cavitary bone defect of long bones as comp ared to tobramycin-impregnated calcium sulfate.

Introduction Herniated disks are very common. Percutaneous endoscopic lumbar spine surgery for the lumbar disc herniation facilitates minimalized access ports to the operating site with decreased risk of infection, reduced blood loss and less tissue dissection and muscle trauma. The goal was to compare the results of standard transforaminal endoscopic discectomy for lumbosacral herniation and outcomes of the procedure added by nucleoplasty. Material and methods Percutaneous transforaminal endoscopic discectomy was performed for 92 patients and added by nucleoplasty in 43 patients of group I. Preoperative and postoperative evaluation was produced with the Visual Analog Pain Scale (VAS), the Oswestry Low Back Pain Disability Questionnaire (ODI) and the MacNab clinical outcome score. Complication and recurrence rate was reviewed. Microsoft Office Excell and Statistica 8.0 were used to complete data analysis reports. Results VAS scores decreased from 7.9 to 3.1 showing 2.5-fold decrease (p < 0.05), and ODI scores decreased from 71.09 to 18.58) (p < 0.001) demonstrating fourfold decrease at one-year follow-up. There were no significant differences in VAS and ODI scores between the groups preoperatively and postoperatively (p > 0.05). The majority of patients of group I (41.86 %) rated their health status as excellent on the MacNab scale, and the majority of patients of group II (53.06 %) rated their health status as good. Postoperative complication rate was 11.63% in group I and 12.24% in group II (p > 0.05). There was no recurrence in group I with the recurrence rate of 6.1% (p < 0.001) in group II. Conclusion Endoscopic discectomy for lumbosacral herniation supplemented with nucleoplasty can reduce the recurrence rate.

Published: April 2021

This scientometric analysis of 393 original papers published from January 2000 to June 2019 describes the development and use of bioinks for 3D bioprinting. The main trends for bioink applications and the primary considerations guiding the selection and design of current bioink components (i.e., cell types, hydrogels, and additives) were reviewed. The cost, availability, practicality, and basic biological considerations (e.g., cytocompatibility and cell attachment) are the most popular parameters guiding bioink use and development. Today, extrusion bioprinting is the most widely used bioprinting technique. The most reported use of bioinks is the generic characterization of bioink formulations or bioprinting technologies (32%), followed by cartilage bioprinting applications (16%). Similarly, the cell-type choice is mostly generic, as cells are typically used as models to assess bioink formulations or new bioprinting methodologies rather than to fabricate specific tissues. The cell-binding motif arginine-glycine-aspartate is the most common bioink additive. Many articles reported the development of advanced functional bioinks for specific biomedical applications; however, most bioinks remain the basic compositions that meet the simple criteria: Manufacturability and essential biological performance. Alginate and gelatin methacryloyl are the most popular hydrogels that meet these criteria. Our analysis suggests that present-day bioinks still represent a stage of emergence of bioprinting technology.
Ageism in the context of healthcare in Canada
Authors: Mistry Neel
Published: April 2021

Ageism is prevalent in Canadian healthcare settings. On average, Canadian seniors spend less time talking to their healthcare professionals (HCPs) than any other age group. However, even when seniors are allowed to see a HCP, they are subjected to discrimination based on age. This can lead to blunders in care such as undertreatment and/or overtreatment, misinterpretation of cognitive impairment as functional impairment, and ineffective communication that is, ultimately, patronizing. Combating ageism will require implementing a strategy that entails training HCPs, revising institutional procedures, and addressing ageist attitudes amongst care providers and elderly patients.

Authors: Esmail Kaisra , Nanji Keean , Ziai Setareh
Published: April 2021

Objective: To evaluate the effectiveness of a novel patient intake form in an emergency ophthalmology clinic at a Canadian academic center. Despite the popularity of intake forms, they have not been previously reported in the literature in an emergency ophthalmology clinic setting.

Methods: All new patients at the University of Ottawa emergency ophthalmology clinic were provided with a patient intake form to complete while waiting to be seen. Ophthalmology residents and nurses at the University of Ottawa completed an effectiveness survey evaluating the benefits of these forms after 24 months of use. Emergency ophthalmology clinics at other Canadian academic institutions were questioned regarding their use of patient intake forms. 

Results: Nine residents and two nurses completed the effectiveness survey. The mean (SD) score assessing the use of the form (1=never, 5=every patient encounter) was 3.90 (1.20). The greatest perceived benefit involved improved clinic efficiency (91%). All (100%) of responses indicated that the form should continue to be used in practice. Of the other 14 ophthalmology residency programs in Canada, nine currently do not use an intake form, two have forms completed by nurses and three utilize a form but are dissatisfied with their results.

Conclusions: Our results suggest that there are benefits with respect to clinic efficiency, accuracy of medical information, collaboration between healthcare professionals, and patient satisfaction when utilizing patient intake forms in an emergency ophthalmology setting. The use of similar forms may provide an opportunity to improve clinical practice at other academic institutions within Canada.
Supporting the Development of Physician-scientists
Authors: Deng Mimi Xiaoming
Published: April 2021

In the last decade, there has been a discrepancy between the increasing recognition for research involvement in medical training and the stagnation in the number physician-scientists. Health research funding cutbacks, inadequate mentorship, heavy schedules, and unfamiliarity with scientific methodology are obstacles that limit research interest amongst junior medical learners and cause attrition of promising physician-scientist in training. This article outlines five strategies to promote and facilitate the development of physician-scientists with the understanding that research is integral to clinical excellence. Some of the ways the undergraduate and postgraduate medical curricula can better lend themselves to producing clinicians with the skillset to address clinical uncertainties through an evidence-based approach are: partnerships between healthcare and academia, increasing admission to MD/PhD and Clinical Investigator programs, establishing fundamentals of scientific thinking, long-term research mentorship, facilitating knowledge translation.

Published: April 2021

Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive species in the United States representing a great threat to crops of economic importance, such as soybean and corn. Due to the lack of information about its damage to early vegetative-stage corn, this study was conducted to provide information about H. halys damage to sweet corn seedlings. In the field experiment, caged sweet corn seedlings were exposed to sexed H. halys adults of densities of 0, 1, or 2 insects per plant for 7 d. In a complementary greenhouse experiment, caged sweet corn seedlings were exposed to 0 or 2 nonsexed H. halys at different stages (second to fifth instars and adult) per plant for 14 d. In both experiments, we evaluated plant fresh and dry weights, plant height, stalk diameter and plant injury (using a rating scale, 0 to 5). In the field experiment, plant injury based on the rating scale was greater in plants exposed to insects compared with the control. In the greenhouse experiment, fresh and dry weights, height and diameter of seedlings were lower for those exposed to fourth instars. This stage also caused greater injury based on the rating scale. In general, our results indicate that H. halys can feed on sweet corn seedlings, and that fourth instars cause more injury. The rating scale adapted here can be used for early identification of H. halys occurrence and to assess its injury in the field.

Containment of pandemic infections mainly depends on prompt identification of carriers, achievable through strict surveillance and truthful diagnostic testing. Although molecular identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the gold standard method, its low sensitivity and long turnaround time are among major concerns. In this retrospective single-center study, we reviewed the results of the lymphocyte and neutrophil counts of 1450 Iranian patients with coronavirus disease 2019 (COVID-19) recruited at Baqiyatallah Hospital, Tehran, Iran. Of 1450 patients, 439 cases (30.3%) were polymerase chain reaction (PCR) negative; further emphasizing that getting negative molecular testing is not as reliable as a positive result. While the lymphocyte count in cases with less than 50 years old was 1.8×103/µL (1.2-2.5), it was 1.47×103/µL (0.84-2.16) in the older group (p<0.001). Also, men experienced lower lymphocytes as compared to women (1.53×103/µL vs 1.76×103/µL; p=0.002). Of particular interest, the lymphocyte count in the PCR-negative cases was 1.77×103/µL (0.98-2.45) which was significantly higher than its count in their positive counterparts (1.53×103/µL; p=0.004). Unlike lymphocytes, sex and PCR did not significantly affect the number of neutrophils. The odds ratio for neutrophilia in patients aged older than 50, either with a negative or a positive PCR, was 2.46 and 2.23, suggesting old age as the most significant associated factor.

Exosomes are extracellular vesicles that are involved in intracellular communication and different biological processes. Recently, the importance of microRNAs (miRNAs) in exosomes has been considered as biomarkers in asthma diagnosis. This study aimed to determine the expression of selective miRNAs from plasma-derived exosomes in moderate and severe asthmatic patients compared with healthy controls. Forty-six subjects including 22 patients with severe and mild to moderate allergic asthma and 24 healthy controls have entered this study. MiRNAs were extracted from the plasma exosomes and selective miRNAs (miR-21, miR-16, miR-Let7, miR-148a, miR-155, miR-125, miR-150, miR146a, miR-223, miR-126) expressions levels were determined; using quantitative polymerase chain reaction (qPCR). In this study, we found a significant up-regulation of miR-223 and miR-21 in moderate asthmatic patients compared to the healthy controls (p=0.002, p=0.006). MiR-223 and miR-21 had the probability of 83% and 76% diagnosis estimation in moderate asthmatic patients respectively. Therefore, they could be used as biomarkers in these patients. No expression of miR-125, miR-126, and miR-155 was found in plasma exosomes by qPCR in this study. The other miRNAs had no significant expression between different groups. Based on our findings, miR-223 and miR-21 may be considered biomarkers or used for targeted immunotherapies in asthma.

Gluten sensitivity contributes to various degrees of neurological manifestations and neurodegenerative immunological changes. We investigated the experimental features of antigliadin immune responses in the central nervous system (CNS) of mice. Female C57BL6 mice were divided into three groups. Mice immunized with complete Freund's adjuvant (CFA) or gliadin emulsified in CFA, and the control group received phosphate-buffered saline (PBS). Immunohistochemistry, hematoxylin-eosin, and Luxol fast blue staining were performed on the sections. The serum levels of interleukin (IL)-17 and interferongamma (IFN-γ) were measured using enzyme-linked immunosorbent assay (ELISA). Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to assess the mRNA levels of chemokine (C-X-C motif) ligand-2 (CXCL-2), C-C motif chemokine ligand-2 (CCL-2), and CXCL-10. In gliadin+CFA immunized mice, the microscopic lesions included perivascular edema, focalmicrogliosis, and acute neuronal necrosis in the cortex, subcortical, Purkinje cell layer, and ventral horn of the spinal cord. While extravasation of anti-IgG antibodies and selective targeting of Purkinje cells were observed in gliadin+CFA immunized mice. A significant increase in serum IL17 and IFN-γ levels (p<0.05), as well as expression of CXCL-2, CCL-2, and CXCL-10 in mice immunized with gliadin+CFA, were monitored versus controls. Our findings indicated that the immune responses directed against gliadin peptides might contribute to blood-brain barrier breakdown, extravasation of serum anti-IgG, gliosis, and acute neuronal necrosis in the cortex and cerebellar Purkinje cells. Anti-IgG antibodies may cause extravasation of blood-born anti-gliadin antibodies and selective targeting of Purkinje cells observed in mice immunized with peptide tryptic (pt) -gliadin in CFA.

Background: The role of pharmacists has evolved from drug provision to patient care. Considering the Doctor of Pharmacy curriculum in Iran and the small number of programs on pharmaceutical care, Iranian pharmacy graduates may not be able to adjust to their new roles.
Methods: A comprehensive online modular course was prepared by a group of well-experienced faculty members of eight universities of medical sciences in Iran. The course included 12 practical and challenging submodules on commonly encountered disorders and commonly used medications in the community pharmacy. Each submodule was followed by an online forum in which the teachers and participants discussed the educational questions. The increase in participants’ knowledge was evaluated using pre-and post-test. The usefulness of submodules and acceptance of the entire course were also evaluated by two specifically designed questionnaires.
Results: After the announcement, 154 participants registered in the course. The knowledge of the participants increased significantly in all the 12 submodules. The majority of participants stated that all the submodules were useful. Moreover, the majority of respondents to questionnaires declared that the course has increased their confidence in providing patient counseling in the pharmacy.
Conclusion: The comprehensive online course on patient counseling in the community pharmacy increased participants’ knowledge. Besides, the course was useful and well accepted by the participants.

Published: April 2021

Este artigo propõe uma análise comparativa em termos da potência ativa e não-ativa processada entre dois conversores CC–CC H-bridge/push–pull configurados como reguladores série abaixadores/elevadores de tensão em sistemas fotovoltaicos (FV), os quais possibilitam a realização do processamento parcial de potência (PPP). Estes reguladores são o full-bridge phase-shift/push–pull alimentado em corrente (FBPS/CFPP) e o conversor proposto, o half-bridge simétrico/push–pull alimentado em corrente (SHB/CFPP). Para avaliar o processamento de potência, utiliza-se um procedimento baseado na teoria de Fryze das potências. Com base na faixa de regulação de tensão e na análise da potência processada, demonstra-se que o FBPS/CFPP e o SHB/CFPP adquirem a capacidade de realizar o PPP mediante a otimização da relação de espiras dos transformadores, sendo que o SHB/CFPP alcança o menor processamento ponderado de potência não-ativa, em razão de a modulação phase-shift utilizada pelo FBPS/CFPP produzir uma potência processada maior nesta aplicação FV. Para validar as abordagens, três protótipos de 2200 W foram construídos e ensaiados. Os resultados experimentais comprovam que a redução da potência ativa e não-ativa processada resulta em maiores eficiências.
Cmentarz ewangelicko-augsburski w Ozorkowie i pomniki rodziny Schlösserów
Authors: Stefański Krzysztof
Published: April 2021

Ozorków to jedno z kilku przemysłowych miast otaczających Łódź, które powstało w ciągu XIX wieku. Główną rolę w rozwoju miasta odegrała działalność rodziny Schlösserów. Pozostałością znaczenia rodziny jest ich pole grobowe na cmentarzu ewangelicko-augsburskim w Ozorkowie, zajmujące znaczną przestrzeń i wypełnione kilkunastoma nagrobkami członków rodziny oraz blisko z nimi spokrewnionych Wernerów. Powstawały one w ciągu stu lat i prezentują różne formy artystyczne oraz różne techniki, dobrze ilustrujące przemiany w sztuce sepulkralnej przełomu XIX i XX wieku. Do najciekawszych należy wykonany z żeliwa grobowiec Fryderyka (Friedricha) Schlössera oraz granitowy sarkofag Henrietty Wilhelminy Schlösser z Wernerów. Na uwagę zasługuje także marmurowy grobowiec Karola Jana Wernera oraz jego żony Emilii z domu Schlösser, sygnowany jako jedyny z omawianego zespołu – autorstwa łódzkiego rzeźbiarza Ludomira Wąsowskiego. Najważniejszym elementem pola grobowego jest kaplica-mauzoleum Henryka (Heinricha) i Karola (Carla) Schlösserów. Kamienna budowla nie jest ściśle datowana i nie jest znany jej autor. Prezentuje formy klasyczno-renesansowe, a jej oryginalnym elementem jest portal wejściowy z motywami egipskimi.

Omawiany zespół sepulkralny w Ozorkowie nie był do tej pory tematem bardziej dogłębnych badań, a zasługuje na wyeksponowanie ze względu na swoje znaczenie historyczne, związane z dziejami przemysłowymi regionu, oraz artystyczne, prezentując ciekawe formy i wysoki poziom wykonawstwa.
Ochrona niezamożnych konsumentów na rynku usług finansowych
Authors: Ćwieląg Krzysztof , Maciejasz-Świątkiewicz Marta
Published: April 2021

Opracowanie stanowi próbę odpowiedzi na pytanie, czy ochrona osób niezamożnych na rynku usług finansowych powinna być realizowana odrębnie w stosunku do powszechnie obowiązujących zasad oraz jakie elementy powinna obejmować ta ochrona? Ponadto – jakie podmioty powinny jej udzielać – czy te, które już istnieją na rynku, czy inne, nowe? Problem ochrony osób niezamożnych wynika stąd, że w dużej mierze osoby te są wykluczone z rynku podstawowego (mainstream market), objętego ochroną prawną. Część osób korzysta z oferty rynku alternatywnego, czy wręcz nieformalnego. Wydaje się więc, że dodatkowa ochrona osób niezamożnych powinna być ukierunkowana na te właśnie obszary rynku usług finansowych.

alianza arquitectónica
Authors: Köncke Florencia
Published: April 2021

El presente artículo indaga en la relevancia que presenta la arquitectura del museo como escenario del encuentro entre la cultura y la ciudad. Siendo la institución museística la principal encargada de adquirir, conservar, estudiar y exponer aquellos objetos que presentan valor cultural y, entendiendo a la ciudad como un conjunto urbano que comprende diversas edificaciones, complejos sistemas viales y un grupo relevante de individuos, se concibe al museo como espacio imprescindible y vínculo trascendente en la reunión de ambos conceptos. Como pieza esencial y articuladora entre el museo y la trama urbana, el vestíbulo condiciona la relación del museo tanto con la ciudad como con la sociedad. A partir de su forma, implantación, escala e incubación de espacios de tránsito o permanencia la arquitectura estipula, condiciona, mejora o rechaza ciertos intercambios. Si bien es evidente que son decisiones morfológicas, espaciales, volumétricas y temporales, también lo son urbanas, políticas y sociales. En ese marco, interesa resaltar que, a fin de cuentas, la arquitectura es el medio a través del cual el arquitecto opina y decide, para bien o para mal, cómo será esa relación.

Authors: López Domínguez Jaime , Ramos Ligonio Angel , Cessa Mendoza Alicia , Mora Díaz Miriam del Carmen , Romero Cruz Víctor Adolfo , López Monteon Aracely
Published: April 2021

La enfermedad de Chagas es una infección causada por el parásito 'Trypanosoma cruzi'. En el mundo, existen millones de personas infectadas, causando entre 10 y 50 mil defunciones anualmente. El diagnóstico de esta enfermedad se realizó por métodos indirectos y moleculares. La selección del método se basa en la fase clínica por la cual cursa la enfermedad. Sin embargo, existe una gran cantidad de resultados falsos positivos o negativos, debido principalmente a tres posibles causas: variabilidad genética entre cepas, reactividad cruzada con antígenos de parásitos de la misma familia y la fase de la enfermedad en la que se realiza el diagnóstico. El objetivo de este trabajo es dar a conocer de manera general los métodos de diagnóstico, ventajas y desventajas y las perspectivas del diagnóstico para la enfermedad de Chagas.

Published: April 2021

La gale du porc, due à Sarcoptes scabiei var. suis, est l’une des principales dermatoses porcines, présente dans de nombreux élevages. Elle provoque d’importantes pertes économiques dans plusieurs pays et son éradication passe par une amélioration des conditions d’hygiène. En l’absence de données récentes sur la prévalence de cette infestation au Cameroun, la recherche des parasites par raclages cutanés a été réalisée dans 52 élevages de la région de l’Ouest (département de la Mifi). En avril-août 2015, puis en avril-août 2016, 359 raclages cutanés sur 103 truies, 39 verrats et 217 porcelets sevrés ont permis d’identifier S. scabiei var. suis dans 23,1 % des élevages (12/52 ; soit 40 porcheries exemptes de gale) avec une prévalence moyenne de 19,5 % (70/359), sans différence de sexe ni d’âge. Les porcheries les plus infestées étaient celles où l’hygiène était la plus défectueuse. Des programmes d’éducation sanitaire doivent être mis en place pour sensibiliser les éleveurs à l’importance du respect des règles d’hygiène dans la lutte contre la gale porcine.
A gyümölcsültetvények hatékonysági elemzése
Authors: Horváth Diána , Regős Gábor , Molnár Dániel
Published: April 2021

A tanulmány a 2017-re vonatkozó, 2018. évi magyarországi gyümölcsültetvény-összeírás adatait elemzi. Célja az ültetvények fő jellemzőinek ismertetése mellett annak vizsgálata, hogy milyen homogén ültetvénycsoportok képezhetők e jellemzők alapján, illetve mely tényezők befolyásolják a gyümölcsfajok terméshozamát. Az eredmények szerint az ágazatban fejlesztésre szorul a felszereltség (például öntözés, támrendszer), valamint hosszabb távon nehézséget jelenthet a generációváltás. A becsült regressziók magyarázóereje a felmérésbe be nem vont változók miatt alacsony, ezért megállapítható, hogy az ültetvények jellemzői és a gazdaságok irányítóinak szociodemográfiai sajátosságai csak kismértékben magyarázzák a terméshozamok alakulását. Továbbá kimutatható néhány változó (különböző védelmi eljárások, az ültetvények jobb kondíciója, a gazdaságok irányítóinak magasabb szintű mezőgazdasági végzettsége) hatékonyságra gyakorolt pozitív vagy (például bioültetvények) negatív hatása is. A szerzők által végzett klaszteranalízis alátámasztja, hogy minden gyümölcsfaj esetében van néhány kiemelkedő, az átlagnál jobban teljesítő ültetvény, de a többség terméshozama csak kevéssé tér el az átlagtól.
Quand le corps(s') énonce
Authors: Georges Hani
Published: April 2021

Dans Le Journal d'une femme de chambre, Célestine nourrit un projet de démystification de la morale bourgeoise mais en même temps elle nous  rapporte ses expériences et ses relations amoureuses. Son corps s'avère donc l'opérateur principal autour duquel le journal se construit car la diariste tend à y enregistrer ses expériences les plus marquantes. A étudier sémiotiquement les empreintes qui ont affecté le corps de la femme de chambre tout au long de son parcours discursif , nous pourrions alors explorer à fond le processus énonciatif qui a donné naissance au journal conçu alors comme l'itinéraire de ces empreintes corporelles.
"Encontré tres palabras para jugar hoy: exacto, excéntrico, extremo": el efecto performático en los cuentos de Nadine Alemán
Authors: Basso Benelli Cristián
Published: April 2021

Current Argentinean Patagonian narrative possesses Nadine Alemán (Esquel, 1977) as one of its most suggestive and creative voices. This assertion is based on her capacity to construct a narrative imaginary that produces performance effects, derived from the confluence and evocation of other languages that can be found in the literary reception of 17 simples cuentos (2006) and of El cura y la sucia (2012). The traditional boundaries that tend to restrict literature to a specific field of critical action seem, in consequence, to become fuzzy. Thus, performance ―as a “methodological lense”, according to Diana Taylor― is made into a certain possibility that widens perspectives to approach this Spanish American writing proposal.
Sappho, Hegel and Michael Field: Paradox and desire in lyric III
Authors: Cantillo-Lucuara Mayron Estefan
Published: April 2021

This article offers a close reading of Katharine Bradley and Edith Cooper’s lyric III in Long Ago, a Sapphic volume of verse published in 1889 under the collaborative nom de plume of Michael Field. This collection articulates a dramatic inquiry into the tragedy of unrequited love in a long cycle of lyrics whose third piece most effectively encapsulates the kernel of what the Fields reconstruct as Sappho’s ambivalent eroticism. The outcome of this reconstruction, as analysed in light of lyric III, is a consistent Hegelian view of desire that subsumes a complex system of tropes, myths, paradoxes and imaginative strategies under an overarching ideology of desire as a radical experience of appropriation, violence and self-destruction.
Of gods and men: Monsters in Mary Shelley’s Frankenstein and Ridley Scott’s Prometheus
Authors: Pekşen Seda
Published: April 2021

This article is a comparison between Mary Shelley’s Frankenstein and the 2012 Ridley Scott movie Prometheus focusing on the destructive consequences of the conflict between the creators and the created each deeming the other as monstrous. Both the novel and the movie are about finding answers to fundamental questions as to one’s nature of existence motivated by a human curiosity and desire for immortality leading to a conflict with one’s creator. The main concern here is to lay bare the blurriness of the lines allegedly separating the monsters from their creators, elucidating the monstrosity of the creators themselves as a product of hubris which eventually leads to a transgression of the boundaries between God/man, man/monster, good/evil and so forth.

Published: April 2021

This study aimed to examine the quality of broiler carcasses in the Banyuwangi traditional market with carcass quality examination based on SNI number 3924-2009 and tetracycline antibiotic residues test based on SNI number 7424:2008. A total of ten broiler chicken sellers as representative of almost all broiler chicken sellers in the Banyuwangi market, with each seller was taken for one carcass in this research. Carcass quality examination used a standart carcasses weight 1,0-1,3 kg. Carcass quality examination was carried out with descriptive analysis with reference to the physical characteristics of SNI (Standarisasi Nasional Indonesia). The bioassay method is used to test for tetracycline antibiotic residue. The result of the carcass quality examination showed that from the whole sample consisting of conformation, disjointed or broken bones and missing parts, discolorations, and cleanliness of broiler carcasses are good enough. The percentage quality of broiler carcasses quality I is 60%, quality II is 30% and quality III is 10%. The examination of antibiotic tetracycline residues in broiler meat showed negative results indicating that no feeds containing additional antibiotics made carcasses in the traditional Banyuwangi market safe for consumption.

Published: April 2021

This study aimed to determine the duration of the process of spermatogenesis in adult Javan langurs (Trachypithecus auratus) by measuring levels of the hormone testosterone and luteinizing hormone (LH), as one of the efforts to increase the success of mating this endemic animals. Two Javan langurs aged 3-5-year-old, named Luki and Moses were taken their feces for 30 days. Feces extraction process used PBS with a ratio of 1: 9, while the measurement of hormone levels used Monkey Luteinizing Hormone ELISA BT Lab brand with Cat.No E0052MK for LH and Cat No E0008MK for testosterone. Hormone consentration data was a graph with fluctuating patterns which are then analyzed descriptively. The results of this study were the concentration of the hormone testosterone is in the range of 4.81 ng / gram of feces to 15.08 ng / gram of feces. While LH level is in the range of 12.59 mIU/gram to 26.24 mIU/gram. In conclusion, we could estimated that the duration of the spermatogenesis cycle every month in langur Luki occurs for 14 days, while Langur Moses for 10 days.
