Resumo As perdas de alimentos por contaminação causada por fungos são de grande impacto negativo para a agricultura, gerando altos prejuízos econômicos. Para evitar as perdas de diversos produtos alimentícios pela contaminação fúngica são utilizados fungicidas sintéticos e naturais. As espécies do gênero Capsicum são usadas há muitos anos para auxiliar na conservação de alimentos por possuírem substâncias químicas com ação antifúngica entre outras. Neste contexto, o objetivo deste estudo foi identificar alguns compostos fenólicos por cromatografia líquida de alta eficiência acoplada à espectrometria de massas sequencial (LC-ESI-MS/MS) presentes nos extratos acetato de etila (EAE) e metanólico (ME) dos frutos maduros da pimenta biquinho (C. chinense) e avaliar atividade antifúngica de EAE e ME contra os fungos Sclerotinia sclerotiorum, Rhizopus stolonifer e Colletotrichum gloeosporioides. Os extratos foram obtidos de forma sequencial, utilizando o procedimento de maceração. A atividade antifúngica foi avaliada seguindo a metodologia de difusão em disco, nas doses de 25 µL, 50 µL, 100 µL e 200 µL de cada extrato diluído. A análise química evidenciou a presença de ácido protocatequico, ácido gentisico, ácido vanílico, kaempferol-3-O-robinobiosídeo e naringenina em ambos os extratos. EAE revelou maior poder de inibição do crescimento micelial nas doses de 100µL e 200µL contra os três fungos testados, enquanto ME exibiu fraca atividade inclusive na maior dose investigada. Entretanto, estudos mais aprofundados ainda são necessários para consolidar seu uso e aplicação prática na área agronômica.

Abstract Food loss due to contamination caused by fungi has much impact on agriculture and leads to significant economic losses. Synthetic and natural fungicides have been used for avoiding losses of several food products due to fungal contamination. As a result, species of the genus Capsicum have been used for preserving food because of their chemical compounds with antifungal activity. Therefore, this study aimed at identifying some phenolic compounds found in both ethyl acetate extract (EAE) and methanolic extract (ME) from habanero pepper (C. chinense) ripe fruit by liquid chromatography tandem mass spectrometry with electrospray ionization (LC-ESI-MS/MS) and at evaluating their antifungal activities against fungi Sclerotinia sclerotiorum, Rhizopus stolonifer and Colletotrichum gloeosporioides. Extracts resulted from a sequential process of maceration. Antifungal activity was evaluated by the disk diffusion method (DDM) at the following doses of both diluted extracts: 25 µL, 50 µL, 100 µL and 200 µL. The chemical analysis showed that there were protocatechuic acid, gentisic acid, vanillic acid, kaempferol-3-O-robinobiosideo and naringenin in both extracts. EAE showed high inhibition of mycelial growth at both doses 100µL and 200µL against the three fungi while methanolic exhibited weak activity even at the highest dose under investigation. However, further in-depth studies are needed to reinforce their uses and practical applications to the agricultural field.

RESUMEN Objetivos. Explorar la frecuencia e impacto de la violencia contra los trabajadores de salud de Argentina y compararlo con el resto de sus pares de Latinoamérica en el contexto de la pandemia por COVID-19. Materiales y métodos. Estudio de corte transversal a través de una encuesta electrónica al personal médico y no médico de Latinoamérica que desempeño tareas asistenciales desde marzo de 2020. Se utilizó una regresión de Poisson para estimar las Razones de Prevalencia crudas (RP) y ajustadas (RPa) con sus respectivos intervalos de confianza al 95%. Resultados. Un total de 3544 participantes de 19 países respondieron la encuesta; 1992 (56,0%) residían en Argentina. Entre los mismos, el 62,9% padeció al menos un hecho de violencia: 97,7% refirió violencia verbal y 11,8% violencia física. El 41,5% de los agredidos padecieron situaciones de violencia al menos una vez por semana. El personal de salud de Argentina vivenció más frecuentemente violencia que los de otros países (62,9% vs. 54,6%, p<0,001), siendo estos eventos más habituales y estresantes (p<0,05). Además, refirieron más frecuentemente haber considerado cambiar sus tareas asistenciales y/o deseos de abandonar su profesión (p<0,001). En la regresión de Poisson, los participantes de Argentina tuvieron una prevalencia de violencia mayor que los trabajadores de salud de la región (14,6%; p<0,001). Conclusiones. Existió una elevada prevalencia de violencia contra el personal de salud de Argentina durante la pandemia por COVID-19. Estos hechos tuvieron un alto impacto negativo entre quienes los padecieron. Nuestros datos sugieren que, esto podría haber sido más frecuente en Argentina respecto de otras regiones del continente.

ABSTRACT Objectives. To explore the frequency and impact of violence against healthcare workers in Argentina and to compare it with the rest of their Latin American peers during the COVID-19 pandemic. Materials and methods. A cross-sectional study was conducted by applying an electronic survey on Latin American medical and non-medical personnel who carried out health care tasks since March 2020. We used Poisson regression to estimate crude (PR) and adjusted (aPR) Prevalence Ratios with their respective 95% confidence intervals. Results. A total of 3544 participants from 19 countries answered the survey; 1992 (56.0%) resided in Argentina. Of these, 62.9% experienced at least one act of violence; 97.7% reported verbal violence and 11.8% physical violence. Of those who were assaulted, 41.5% experienced violence at least once a week. Health personnel from Argentina experienced violence more frequently than those from other countries (62.9% vs. 54.6%, p<0.001), and these events were more frequent and stressful (p<0.05). In addition, Argentinean health personnel reported having considered changing their healthcare tasks and/or desired to leave their profession more frequently (p<0.001). In the Poisson regression, we found that participants from Argentina had a higher prevalence of violence than health workers from the region (14.6%; p<0.001). Conclusions. There was a high prevalence of violence against health personnel in Argentina during the COVID-19 pandemic. These events had a strong negative impact on those who suffered them. Our data suggest that violence against health personnel may have been more frequent in Argentina than in other regions of the continent.

Resumen Los aneurismas de arteria ilíaca solitarios son menos frecuentes que otros aneurismas de grandes vasos, siendo en la mayoría detectados junto con un aneurisma de aorta abdominal concomitante. Comparten la misma etiología aterosclerótica-degenerativa, siendo así que sus factores de riesgo son los mismos que para otros aneurismas. Generalmente son asintomáticos y se detectan incidentalmente, y cuando son sintomáticos, están en relación con la compresión de estructuras adyacentes y la ruptura del aneurisma. Los aneurismas de la arteria ilíaca común son los más comunes, seguidos de los aneurismas ilíacos internos y luego externos. Actualmente existe una variedad de opciones quirúrgicas abiertas, endovasculares e híbridas para tratar los aneurismas de la arteria ilíaca. La anatomía de la arteria ilíaca común con respecto al cuello proximal y distal, la afectación de la bifurcación ilíaca y la elección de preservar la arteria ilíaca interna ipsilateral juegan un papel en el proceso de decisión hacia el método de tratamiento preferido.

Abstract Isolated iliac artery aneurysms are less common than other large-vessel aneurysms, and most are detected together with a concomitant abdominal aortic aneurysm. It shares the same atherosclerotic-degenerative etiology since its risk factors are the same as for other aneurysms. They are generally asymptomatic, being detected incidentally and when they are symptomatic, they are related to the compression of adjacent structures and the rupture of the aneurysm. Common iliac artery aneurysms are the most common, followed by internal and then external iliac aneurysms. Currently, a variety of open, endovascular, and hybrid surgical options exist to treat iliac artery aneurysms. The anatomy of the common iliac artery with respect to the proximal and distal neck, the involvement of the iliac bifurcation, and the choice to preserve the ipsilateral internal iliac artery all play a role in the decision process towards the preferred method of treatment.

Resumen Antecedentes. La incidencia de carcinomatosis peritoneal (CP) secundaria a cáncer gastrointestinal o ginecológico ha aumentado y tiene peor pronóstico en comparación con otros sitios de metástasis. El índice de carcinomatosis peritoneal (ICP) establece la supervivencia global en pacientes con tumores gastrointestinales o ginecológicos y carcinomatosis. Objetivo. Evaluar la relación del ICP con la supervivencia global (SG) y la supervivencia libre de recurrencia (SLR) en pacientes tratados con cirugía citorreductora (CCR) más quimioterapia intraperitoneal e hipertemia (HIPEC). Método. Estudio descriptivo, retrolectivo, de 80 expedientes de pacientes con CP. Se incluyeron tumores de colon, ovario, apendicular, pseudomixomas y gástricos con CP tratados con CCR + HIPEC. Se determinaron la SG y la SLR de acuerdo con el tipo de adenocarcinoma y el grado de diferenciación, en meses, en pacientes con ICP > 15 y con ICP < 15 considerando el tumor de origen. Resultados. Los pacientes con tumores de ovario y pseudomixoma con ICP < 15 tenían una SG > 70 meses, frente a 4 meses con tumores gástricos. Conclusiones. El ICP y la histología son predictores de la SG. Las pacientes con tumores ováricos con ICP < 15 tienen mayor SG, igual que los pseudomixomas. La SLR fue mayor en los pacientes con ICP < 15.

Abstract Background. The peritoneal carcinomatosis (PC) secondary to gastrointestinal or gynecological cancer has increased its incidence. It has a worse prognosis compared to other sites of metastasis. The peritoneal carcinomatosis index (PCI) establishes overall survival in patients with gastrointestinal or gynecological tumors and carcinomatosis. Objective. To evaluate the relationship of PCI to overall survival (OS) and recurrence-free survival (RFS) in patients treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC). Method. A descriptive, retrolective study of 80 charts of patients with CP was conducted. We included patients with colon, ovarian, appendicular, pseudomyxoma and gastric tumors with CP treated with CRS plus HIPEC. The OS and RFS were determined according to the type of adenocarcinoma and the degree of differentiation. The OS and RFS were determined in months in patients with PCI > 15 PCI as well as in patients with PCI < 15 considering the tumor of origin. Results. Patients with ovarian tumors and pseudomyxoma with PCI < 15 presented OS > 70 months, compared to patients with gastric tumors (4 months). Conclusions. The PCI and histology are predictors of OS. Patients with ovarian tumors and PCI < 15 have higher OS, similar to pseudomyxomas. RFS was also higher in patients with PCI < 15.

Resumo Persea lingue Ness é uma árvore que vive principalmente na floresta temperada do centro-sul do Chile. As folhas são usadas na etnomedicina. O fruto é uma drupa similar ao abacate e que nunca foi pesquisada anteriormente. O objetivo deste estudo foi o de avaliar a citotoxicidade em células leucêmicas e as atividades antibacterianas, assim como algumas características químicas do extrato de fruto e da folha do P. lingue. As atividades antibacterianas foram determinadas pelo método da inibição do crescimento bacteriano em meio líquido empregando-se bactérias Gram-positivas e Gram-negativas. As linhagens celulares leucêmicas, Kasumi-1 e Jurkat foram usadas para avaliar a atividade citotóxica em ensaios empregando-se iodeto de propídio e AlamarBlue. Foram avaliados os teores totais de fenóis, flavonóides, taninos condensados, alcalóides e lipídeos presentes nos extratos das folhas e dos frutos. As atividades antioxidantes de ambos os extratos também foram avaliadas. O extrato das folhas foi o que apresentou o maior conteúdo de fenóis, taninos condensados e flavonóides totais e a maior atividade antioxidante. Já o extrato de fruto apresentou a maior quantidade de lipídios e alcaloides e a melhor atividade antibacteriana contra Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus megaterium e Micrococcus luteus. Já o extrato das folhas apresentou apenas atividade contra M. luteus. Em relação à atividade citotóxica, apenas o extrato do fruto apresentou citotoxicidade contra as linhagens celulares Jurkat e Kasumi-1. Em resumo, o extrato do fruto de P. lingue é uma potencial fonte de moléculas com atividade biológica para o desenvolvimento de novos fármacos a serem utilizados em alguns tipos de leucemia, bem como agente antibacteriano.

Abstract Persea lingue Ness is a tree species that lives mainly in temperate forests of south-central Chile. Its leaves are used in ethnomedicine, the fruit is a drupe similar to that of the avocado and has not been studied. The aim of this study was to determine the cytotoxicity in leukemia cell and antibacterial activity, along with some chemical content characteristics of P. lingue fruit and leaf extracts. The antibacterial activity was determined by the inhibition of bacterial growth in liquid medium assay against Gram-positive and Gram-negative bacteria. The leukemia cell lines Kasumi-1 and Jurkat were used to evaluate the cytotoxic activity by using propidium iodide and AlamarBlue assays. Total phenolic, flavonoid, condensed tannin, alkaloid and lipid contents were evaluated in the fruit and in the leaf extracts. The antioxidant activity of both extracts were also elavaluated. Leaf extract presented the highest content of total phenols, condensed tannins and flavonoids, and also the highest antioxidant activity. While the fruit extract has a higher amount of lipids and alkaloids and the high antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus megaterium and Micrococcus luteus. The leaf extract only showed activity against M. luteus. Concerning the cytotoxic activity, only the fruit extract showed cytotoxicity against the cell lines Jurkat and Kasumi-1. P. lingue fruit extract is a potential source of biologically active molecules for the development of new drugs to be used in some types of leukemia, as well as antibacterial agent.

Abstract In this work, a thermal plasma-based ablation test system was used to evaluate the ablative performance of the EPDM composite. The system produces a high enthalpy plasma jet generated by a plasma (DC) torch, operating at atmospheric pressure using compressed air as working gas, enabling the variation of the thermal flux concerned with the studied EPDM composites. The samples were characterized using Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Fourier-Transform Infrared spectroscopy (FTIR), and Thermogravimetric Analysis (TGA) to investigate the morphology, mass-loss rate, the reaction layer (char formation), and chemical changes of the samples for each thermal flux. For a complete evaluation, the thermal fluxes were varied in 0.30, 0.45, 0.60, 0.75, and 0.90 MW/m2 and for each thermal flux, disk-shape samples remained exposed to the plasma jet for 10s. During the plasma jet exposure time, the temperatures of the surface and the back of the samples were collected to verify the formed char layer's insulator capacity and the samples' thermal diffusivity for each experimental condition. The mass loss is continuous under the thermal fluxes of 0.30 and 0.45 MW/m2, stabilizing at 60% until 0.75 MW/m2. The formed char layer begins to lose its protective capacity, evidenced by the size decrease (from 800 µm to 700 µm), due to the ablation process of the reaction layer from the thermal flux of 0.90 MW/m2.

Abstract Venous aneurysms are rare and have a prevalence of 0.1 to 0.2% in the reported series. Typically, patients do not present any symptoms, but are prone to develop deep venous thrombosis (DVT) and the most feared complication, pulmonary embolism (PE). We present the case of a previously healthy 36-year-old man who presented at the emergency department with tachycardia, dyspnea, and pleuritic pain. A thoracic computed tomography angiography (CTA) confirmed the diagnosis of acute pulmonary embolism. He was treated with systemic thrombolysis and anticoagulation. In the further workup of the cause of the embolism, computed tomography revealed a fusiform dilation of the left popliteal vein measuring 3 by 3 centimeters (cm) with an incomplete filling defect because of thrombus presence. The patient underwent open surgical repair. At one month follow-up, he was asymptomatic, and an ultrasound revealed complete patency of the popliteal vein without dilatation or thrombus.

Resumo Aneurismas venosos são raros, tendo uma prevalência de 0,1 a 0,2% nas séries relatadas. Os pacientes não costumam manifestar sintomas; entretanto, são propensos a desenvolver trombose venosa profunda e a complicação mais temida, embolia pulmonar. Apresentamos o caso de um homem de 36 anos previamente hígido que chegou ao serviço de emergência queixando-se de taquicardia, dispneia e dor pleurítica. Uma angiotomografia computadorizada confirmou o diagnóstico de embolia pulmonar aguda. O paciente foi tratado com trombólise sistêmica e anticoagulantes. Em exames posteriores para investigar a causa da embolia, uma tomografia computadorizada revelou dilatação fusiforme da veia poplítea esquerda medindo 3x3 cm, com enchimento incompleto devido à presença de um trombo. O paciente foi submetido a reparo cirúrgico aberto. No seguimento de 1 mês, ele estava assintomático, e uma ultrassonografia revelou a patência completa da veia poplítea, sem dilatação ou trombo.

ABSTRACT Entomopathogenic fungi stand out in the biological control of several agriculturally important insects. Six isolates of Metarhizium anisopliae, Cordyceps javanica, Beauveria sp. and B. bassiana were screened to control Anthonomus grandis, Euschistus heros, Oebalus poecilus, O. ypsilongriseus and Thyanta perditor, important insect pests of soybean, cotton and rice. The bioassays were conducted in a completely randomized design, with four replications (10 insects/replication). Significant differences for virulence were observed between the tested fungal species and isolates. For A. grandis, the most virulent isolate was M. anisopliae BRM 2335, followed by Beauveria BRM 14527 and BRM 67744 [82.5 to 97.5 % of mortality; average lethal time (LT50) of 5.9 to 7.8 days]. M. anisopliae BRM 2335 was also highly virulent to the four stink bug species (75 to 97.5 % of mortality; LT50 of 5.2 to 9.7 days). For the stink bugs, Beauveria sp. BRM 67744 was infectious to O. poecilus (75 % of mortality), but failed to control E. heros (16.9 % of mortality). C. javanica BRM 27666 and BRM 14526 showed average virulence to the stink bugs and A. grandis (17.5 to 57.3 % of mortality; LT50 of 6.0 to 9.7 days). M. anisopliae was consistently more virulent to the stink bugs than the other fungi. Therefore, M. anisopliae BRM 2335 was selected for further studies under screenhouse and field conditions to control A. grandis and other stink bug species, especially E. heros.

RESUMO Os fungos entomopatogênicos destacam-se no controle biológico de diversos insetos de importância agrícola. Seis isolados de Metarhizium anisopliae, Cordyceps javanica, Beauveria sp. e B. bassiana foram selecionados para o controle de Anthonomus grandis, Euschistus heros, Oebalus poecilus, O. ypsilongriseus e Thyanta perditor, importantes insetos-pragas da soja, algodão e arroz. Os bioensaios foram conduzidos em delineamento inteiramente casualizado, com quatro repetições (10 insetos/repetição). Foram observadas diferenças significativas, em termos de virulência, entre as espécies fúngicas e isolados testados. Para A. grandis, M. anisopliae BRM 2335 foi o isolado mais virulento, seguido por Beauveria BRM 14527 e BRM 67744 [82,5 a 97,5 % de mortalidade; tempo letal médio (TL50) de 5,9 a 7,8 dias]. M. anisopliae BRM 2335 também foi altamente virulento para as quatro espécies de percevejo (75 a 97,5 % de mortalidade; TL50 de 5,2 a 9,7 dias). Para os percevejos, Beauveria sp. BRM 67744 foi infeccioso para O. poecilus (75 % de mortalidade), mas falhou no controle de E. heros (16,9 % de mortalidade). C. javanica BRM 27666 e BRM 14526 apresentaram virulência mediana para os percevejos e A. grandis (17,5 a 57,3 % de mortalidade; TL50 de 6,0 a 9,7 dias). M. anisopliae foi consistentemente mais virulento aos percevejos do que os outros fungos. Portanto, M. anisopliae BRM 2335 foi selecionado para estudos posteriores em casa telada e campo para o controle de A. grandis e outras espécies de percevejo, principalmente E. heros.

ABSTRACT Background: The biodiversity of the Peruvian Amazon tropical forests is one of the most expressive in the world, with 2500 forest species, although restricted to about 250 tree species used commercially. This species diversity indicates the challenge magnitude for research in taxonomy and timber species identification. Likewise, it implies the complexity of biodiversity conservation and restoration measures, which are directly related to the control of deforestation, cutting and transport of illegal wood. With this objective, the present study describes the macroscopic wood anatomical features in order to identify 20 tree species from Peruvian Amazon Forest, “Selva Central”, including an identification key and tree species botanical validation. Results: The wood species are included in 12 families commonly found in the tropical forests of Peru, highlighting the Fabaceae (25%), Moraceae (15%), Podocarpaceae and Lauraceae (10%) families and are sold as timber for several uses and applications in the internal market and for export. The wood species presented common anatomical features, such as diffuse porosity, visible axial parenchyma mainly distinct, and, eventually, with ray storied, e. g: A. cearensis, M. balsamum and M. peruiferum. Conclusion: The tropical tree species identification is possible by analyzing their wood macroscopic anatomical structure. The results can be also applied in the wood trade traceability by controlling deforestation and illegal wood commerce and in proposing policies for biodiversity conservation and sustainable use of natural resources. They constitute, likewise, a database for the recent wood identification methodologies presented in the specialized literature.

RESUMEN: Este artículo analiza cómo se aborda la enseñanza del golpe de Estado y la dictadura civil-militar entendida como un tema controversial, y cómo se vincula con las expectativas del profesorado sobre su enseñanza. Surge a partir de un proyecto en el que participan tres carreras de formación del profesorado de una universidad pública y cinco establecimientos educacionales de Santiago, desarrollado con el propósito de fortalecer una ciudadanía crítica en los espacios escolares a partir de la enseñanza del golpe de Estado y la creación de artefactos de memoria. Se optó por una metodología cualitativa con utilización de técnicas provenientes del análisis del discurso y documental. Como principales hallazgos se revela que el diseño de la enseñanza del golpe de Estado se aborda desde las múltiples dimensiones de su controversialidad (experiencia y memoria histórica, relevancia en el presente, vulneración de derechos humanos) materializadas en los artefactos de memoria construidos. Dicho abordaje se relaciona directamente con las expectativas del profesorado manifestadas como oportunidades, complejidades, tensiones y posicionamiento teórico y expresadas en estrecha relación a través de los distintos componentes de la planificación de la enseñanza. En conclusión, la controversialidad posibilita y desafía el ejercicio de la problematización curricular y se resuelve en el plano didáctico a partir de actividades y experiencias de memoria.

ABSTRACT: This article analyses how the teaching of the military coup and the civil-military dictatorship in Chile is approached, understood as a controversial issue, and how it is linked to teachers’ expectations about their own instruction. The article arises from a project developed by three initial teacher training programs at a public university and five educational establishments in Santiago, with the purpose of strengthening critical citizenship in school spaces based on the teaching of the military coup and the creation of memory artifacts. A qualitative methodology was chosen with the use of techniques from discourse and documentary analysis. The main findings reveal that the design of the teaching of the military coup is approached from the multiple dimensions of its controversy (experience and historical memory, relevance in the present, violation of human rights) materialised in the constructed memory artifacts. This approach is directly related to the teachers’ expectations expressed as opportunities, complexities, tensions and theoretical positioning and expressed in close relationship through the different components of teaching planning. In conclusion, controversy enables and challenges the exercise of curricular problematization and is resolved on a didactic level based on activities and memory experiences.

Abstract Eagle syndrome is a rare disease responsible for multiple head and neck symptoms, resulting from an elongation of the styloid process or ossification of the stylohyoid ligament compressing adjacent neurovascular structures. There are two variants, the classic one characterized mainly by pain and dysphagia and the carotid variant distinguished with pain and sometimes cerebral ischemia. We describe a clinical case report of a 45-year-old female patient, who experienced left cervical pain, performing the complete myofascial pain protocol of the Regional Hospital "General Ignacio Zaragoza" ISSSTE in Mexico City, resulting in a 50mm elongation of the styloid process in the CT scan, confirming the diagnosis, and focusing the article on the anatomical-surgical description.

Resumen El síndrome de Eagle es una enfermedad rara responsable de múltiples síntomas de cabeza y cuello, resultado de un alargamiento del proceso estiloideo u osificación del ligamento estilohioideo comprimiendo estructuras neurovasculares adyacentes, hay dos variantes, el clásico caracterizado principalmente por dolor y disfagia y la variante carotídea distinguido con dolor y en ocasiones isquemia cerebral. Describimos un reporte de caso clínico de un paciente femenino de 45 años, quien experimentaba dolor cervical de lado izquierdo, realizando el protocolo completo de dolor miofascial del Hospital Regional General Ignacio Zaragoza ISSSTE de la Ciudad de México, el estudio de tomografía computada evidenció una elongación de 50mm del proceso estiloideo, confirmando el diagnóstico, enfocando el artículo en la descripción anatómico-quirúrgica.

Abstract: In type-based program synthesis, the search of inhabitants in typed calculi can be seen as a process where a specification, given by a type A, is considered to be fulfilled if we can construct a λ-term M such that M : A, or more precisely if Γ ⊢ M : A holds, that is, if under some suitable assumptions Γ the term M inhabits the type A. In this paper, we tackle this inhabitation/synthesis problem for the case of modal types in the necessity fragment of the constructive logic S 4. Our approach is human-driven in the sense of the usual reasoning procedures of modern theorem provers. To this purpose we employ a so-called dual-context sequent calculus, where the sequents have two contexts, originally proposed to capture the notions of global and local truths without resorting to any formal semantics. The use of dual-contexts allows us to define a sequent calculus which, in comparison to other related systems for the same modal logic, exhibits simpler typing inference rules for the □ operator. In several cases, the task of searching for a term having subterms with modal types is reduced to the quest for a term containing only subterms typed by non modal propositions.
