Authors: Durmuş Burcu , İşçi Güneri Öznur
Published: October 2020

In the article, it is aimed to investigate the factors affecting survival in today's legendary giant accident with different methods. The analysis aims to find the method that best determines survival. For this purpose, logit and probit models from generalized linear models and random tree algorithm from decision tree methods were used. The study was carried out in two stages. Firstly; in the analysis made with generalized linear models, variables that did not contribute significantly to the model were determined. Classification accuracy was found to be 79.89% for the logit model and 79.04% for the probit model. In the second stage; classification analysis was performed with random tree decision trees. Classification accuracy was determined to be 77.21%. In addition; according to the results obtained from the generalized linear models, the classification analysis was repeated by removing the data that made meaningless contribution to the model. The classification rate increased by 4.36% and reached 81.57%. After all; It was determined that the decision tree analysis made with the variables extracted from the model gave better results than the analysis made with the original variables. These results are thought to be useful for researchers working on classification analysis. In addition, the results can be used for purposes such as data preprocessing, data cleaning.
Classification of Emg Signals Using Convolution Neural Network
Authors: Bakırcıoğlu Kaan , Özkurt Nalan
Published: October 2020

An electrical signal is produced by the contraction of the muscles; this electrical signal contains information about the muscles, the recording of these signals called electromyography (EMG). This information is often used in studies such as prosthetic arm, muscle damage detection, and motion detection. Classifiers such as artificial neural networks, support vector machines are generally used for the classification of EMG signals. Despite successful results with such methods the extraction of the features to be given to the classifiers and the selection of the features affect the classification success. In this study, it is aimed to increase the success of the classification of the daily used hand movements using the Convolutional neural networks (CNN). The advantage of the deep learning techniques like CNN is that the relationships in big data are learned by the network. Firstly, the received EMG signals for forearms are windowed to increase the number of data and focus on the contraction points. Then, to compare the success rate, raw signals, Fourier transform of the signal, the root means square, and the Empirical mode decomposition (EMD) is applied to the signal and intrinsic mode functions are obtained. These signals are given to four different CNN. Afterward, to find the most efficient parameters, the results were obtained by splitting data set into three as 70% training set, 15% validation set, and 15% test set. 5 cross-validations have been applied to assess the system’s performance. The best results are obtained from the CNN, which receive the EMD applied signal as input. The result obtained with the cross-validation is 95.90% and the result obtained with the other separation method is 93.70%. When the results were examined, it was seen that CNN is a promising classifier even the raw signal is applied to the classifier. Also, it has been observed that EMD method creates better accuracy of classification.This is an open access article under the CC BY-SA 4.0 license.(https://creativecommons.org/licenses/by-sa/4.0/)
Usos e funções de ‘praticamente’: de advérbio de modo a angulador
Authors: Abraçado Jussara , De Castro Tainara Pinheiro
Published: October 2020

Este estudo sobre usos e funções de ‘praticamente’ baseia-se em dados contemporâneos do português brasileiro em uso, coletados em diversos sites da internet e no ‘Corpus do português’, e fundamenta-se nos pressupostos teóricos da Linguística Cognitiva, em especial, da teoria dos espaços mentais. Em análise quantitativa (em termos percentuais) e qualitativa dos dados, demonstra que ‘praticamente’: (i) constitui um recurso à disposição dos falantes, que tendem a utilizá-lo em situações em que expressam uma opinião; (ii) atribui algum grau de imprecisão aos significados e, assim sendo, afrouxa o comprometimento com o estatuto de verdade do que está sendo enunciado, atuando na preservação da face dos envolvidos no ato comunicativo; e (iii) tende a ocorrer estabelecendo relação entre entidades pertencentes a uma mesma categoria e inseridas em um mesmo “frame”.
A gramática filosófica de Bernardo de Lima e Melo Bacelar (1783)
Authors: De Melo Lívia
Published: October 2020

A proposta deste artigo é demonstrar as ideias linguísticas e pedagógicas presentes na "Grammatica Philosophica da Língua Portugueza" (1783), de Bernardo de Lima e Melo Bacelar (ca.1736-post.1787), a partir de uma leitura crítica desta obra e da análise de outros estudiosos que já se empenharam em estudá-la. A "Grammatica" é dividida em três partes, de acordo com as partes da oração, conforme suas funções na frase. Estas partes são subdivididas em capítulos. O autor utiliza a nomenclatura casual para descrever os termos da oração. Sua preocupação ao compor a gramática era oferecer aos leitores um material inédito que pudesse apresentar de maneira inovadora as leis que regem a língua portuguesa, pois acreditava que uma comunicação clara, precisa e sem erros somente seria possível através do conhecimento dessas leis. Atento seguidor das ideias racionalistas de "Port-Royal" e do movimento iluminista, acreditava também na existência de uma gramática universal. Embora tenha sido um grande erudito das línguas clássicas e da língua materna, teve sua obra menosprezada pelos estudiosos de sua época, não atingindo, portanto, seus ideais de proporcionar clareza na comunicação.
O estatuto categorial das preposições acidentais/atípicas: a proposição dos “relatores circunstanciais” como classe gramatical
Authors: Wiedemer Marcos Luiz , Pinto de Oliveira Myllena Paiva
Published: October 2020

O objeto de investigação, neste artigo, são as preposições acidentais/atípicas. Analisamos seus usos e, com isso, explicitamos a fluidez dessa classe gramatical, uma espécie de gradualidade, na medida em que podem ser inseridas em diferentes categorizações gramaticais a depender do contexto comunicativo. Como referencial teórico-metodológico, adotamos os pressupostos dos Modelos Baseados no Uso, que coadunam com o princípio de que o estabelecimento de convenções gramaticais é influenciado tanto por estrutura linguística, contexto social e pragmático quanto por aspectos cognitivos. O Iboruna é o Banco de Dados utilizado como amostra para a pesquisa, que reúne dados orais da comunidade de fala do interior paulista. Os resultados apontam seis padrões de usos, em que temos: de um lado, a função relatora caracterizada pela presença de Sintagma Nominal na estrutura subsequente; e de outro, a evidência do aspecto semântico-pragmático comum que todos provocam na estruturam a que se ligam, a função circunstancial. Diferentemente de análises de cunho gramatical, descritivistas e de estudos linguísticos, a partir das evidências aqui apresentadas, denominamos as preposições acidentais/atípicas de “relatores circunstanciais”, “relatores” porque relacionam termos/orações, desempenhando sua função de nexo gramatical, e “adverbiais/circunstanciais” porque, como transpositores, originam construções dessa natureza.

Authors: Aini Fitratul , Maritsa Hasnaul , Riany Hesti
Published: October 2020

Nypa is a mangrove plant that acts as a food source, such as nata. Research has shown that nipah plant waste, such as frond fibers and nipah fruit skin fibers, can be used as a raw material in making nata fruticans. The purpose of this study was to determine the potential of nipah fiber (Nypa fruticans Wurmb.) in nata production using soybean sprouts as a nitrogen source. The samples of nipah fiber (Nypa fruticans) used were leaves (DN), midrib (PN) and fruit skin (KB), taken in the Kuala Tungkal area, West Tanjung Jabung Regency, Jambi Province. This research method includes making the mother solution, making nata starter, and producing nata sheet by using soybean as a source of nitrogen with a concentration of 5%, 10% and 15% and ZA as a control. The results of this study indicate that the best volume and thickness of nata fruticans can be seen from the midrib substrate with a concentration of 10% soybean sprouts. The yields produced for all treatments were still lower compared to controls. Meanwhile, the water content of all treatments was better than the control. The best quality of Nata Fruticans based on thickness, yield and average moisture content was generally obtained from the substrate from the leaf midrib fibers with a concentration of 10% soybean sprouts

Los sitios prehispánicos de la costa oriental de Quintana Roo han tenido siempre un lugar especial en la arqueología maya; se localizan a lo largo de la costa y en las cercanías de la misma; son tan abundantes que no dejan la menor duda que la región estuvo densamente poblada en tiempos prehispánicos (Andrews 1976: 10) (Fig. 1). Quintana Roo se puede dividir en tres provincias geográficas: la sur, cubierta por el bosque tropical y que se extiende un poco a la región central, la cual se caracteriza por el bosque tropical seco, y por ultimo la zona del norte que se localiza en la costa oriental y toda la parte norte.
Informe del reconocimiento arqueológico realizado en la cuenca del Río Candelaria, Campeche
Authors: Ochoa Lorenzo , Vargas Pacheco Ernesto
Published: October 2020

En el año de 1983, durante los meses de octubre y noviembre, los que suscriben, con la asistencia de Sofía Pincemin, estudiante de la Universidad de Paris, llevamos a cabo un reconocimiento arqueológico en las cuencas del río Candelaria y dos menores que dan lugar a este: el San Pedro y el Caribe. El propósito de tal reconocimiento estuvo encaminado a obtener una visión general de la distribución de los asentamientos prehispánicos y la relación que guardan con el paisaje; la localización de los puntos estratégicos utilizados en el tráfico comercial y la corroboración de la posible existencia de sistemas de camellones utilizados en la práctica de la agricultura intensiva. Aunque se dio prioridad al estudio de las cuencas mencionadas, procuramos incluir algunos asentamientos del interior con el objeto de obtener una visión más amplia de la arqueología de esta área tan poco conocida. Nuestra intención, en cuanto al trabajo de campo toca, ha sido seguir un tanto el enfoque de lo que Armillas (1971) ha denominado "arqueología del paisaje", en tanto que no se limita solamente al estudio de la distribución de los sitios en el paisaje, sino a la comprensión de los esfuerzos que hizo y hace el hombre por modificarlo para su explotación y provecho.
Trabajos recientes en Xcaret, Quintana Roo
Authors: Con María José
Published: October 2020

Hace ya más de dos décadas que el ahora estado de Quintana Roo, como parte de la política económica del país, ha venido desarrollándose turísticamente en forma acelerada, especialmente en la franja costera norte y centro del estado, convirtiendo a1 Caribe mexicano en uno de los principales polos turísticos a nivel nacional e internacional. Este crecimiento se tradujo en la construcción masiva de obras de infraestructura turística, principalmente, que generaron cambios significativos en la estructura económica, social y cultural de la comunidad lugareña. Asimismo, la alteración a1 medio natural tanto terrestre como marino es en muchos casos irreversible. Este proyecto arque1ógico, como la mayoría de los realizados por arqueólogos mexicanos en los últimos años, responde a estas transformaciones y a la inminente necesidad de recuperar la mayor cantidad de datos arqueo1ógicos que desaparecen día con día. Si bien es cierto que por una parte estas obras permiten en algunos casos la obtención de fondos para la investigación, por otra, las zonas arqueológicas quedan en su mayoría "cautivas" dentro de las instalaciones turísticas como son los jardines de un hotel o un campo de golf. Esto lleva en ocasiones a pensar si en lugar de que un adoratorio maya quede en el hoyo 10 de un campo de golf, no sería mas digno que sucumbiera bajo el peso de un trascabo.

Son las doce del día del Viernes Santo, en el pueblo Tzotzil de Nabenchauk, "La Laguna del Rayo; en los Altos de Chiapas. Un sol brillante ilumina las paredes de la iglesia de Jch'ul-me'tik Valalupa -la Virgen de Guadalupe- donde el pueblo se ha reunido para acompañar a los ch' ul moletik -los Ancianos Sagrados quc cumplen con sus deberes tradicionales. El pueblo canta en la oscuridad de la iglesia, impregnada de olor a incienso, juncia, rosas, geranios, orquídeas del bosque, y a humo de cientos de velas; y los moletik lavan la figura de Cristo con agua de flores, lo visten con su ropa nueva, lo suben a la Cruz de cuatro metros, donde lo fijan con clavos decorados con listones de colores. Mientras el pueblo llora, arrodillado frente al Cristo crucificado, los moletik salen al sol para compartir sus botellas de pox, y pronunciar las despedidas rituales que marcan el fin de la Semana Santa. Empezando con el menor, y siguiendo hombre por hombre hasta el mayor, los Ancianos Sagrados se saludan, presentando la mano o la frente, y entonando coplas en lenguaje ritual. Las frases de despedida y gratitud se entremezclan en una corriente de palabras.

Los numerales son las palabras que usamos para referimos a los números. Hoy día m tojolabal se están usando poco los numerales para contar y hacer cálculos. Por los contactos comerciales con la sociedad dominante se suelen usar los numerales m castellano, sobre todo de 11 en adelante. Al contar mazorcas sí se siguen usando los numerales en tojolabal. El empleo de los números cubre un campo amplio que, por supuesto, va mucho más allá de contar mazorcas. Al hablar de los numerales nos metemos en algo muy complicado. Es decir, e1 sistema tojolabal de los números, tan distinto de aquel que encontramos en la sociedad dominante.

Lo que Dickens narra para Europa a fines del siglo XIX, ¿son hechos históricos o forman parte de una leyenda? A menudo la información de las fuentes nos plantea esta inquietud, amén de lo escrito sobre las ciudades prehispánica y colonial de Campeche. Por mas que leemos y revisamos los relatos de cronistas españoles al llegar a esta tierra, no nos despejan la duda, ni separan la leyenda de lo que realmente vieron aquellos hombres al desembarcar en ese lugar mítico: Ah Kin Pech.

La preocupación mundial sobre la agricultura de roza, tumba y quema (RTQ) se refleja en la gran cantidad de estudios efectuados en las ultimas cuatro décadas. Una gama de aspectos se ha abordado: por una parte, la configuración topológica y la diversidad de cultivos, las practicas agrícolas, las limitantes y la productividad del sistema y, por otra parte, las condiciones socioeconómicas y las instituciones socioculturales de las comunidades que practican este sistema. Hasta hace pocos años, la mayor parte de los estudios consideraban a la agricultura de RTQ como una adaptación "armónica" al medio, marcando su tendencia a mantener la diversidad y la estructura vegetal de una selva tropical.
Attitudes towards sharing housework in couple context: An empirical, factorial survey approach
Authors: Schulz Florian
Published: October 2020

Objective: This study measured and compared the attitudes of German women and men towards sharing total housework, routine housework and non-routine housework in couples.

Background: Although attitudes towards gender roles and the notion of separate spheres are important for understanding many aspects of family life, knowledge about situational variations of women’s and men’s attitudes towards housework sharing is limited.

Method: Original data from a factorial survey of 1,120 German women and men from 2016 were used to describe variations in the attitudes of women and men towards three sets of housework using multilevel regression models.

Results: Women and men expressed their attitudes towards equal sharing of total and routine housework, but non-routine housework was assigned to male partners in couples. Attitudes differed widely according to the context of the couple: In couples with similar economic resources, respondents favored equal sharing of housework, and in couples with unequal arrangements, the partner with fewer resources was tied to more housework and vice versa.

Conclusion: When evaluating housework responsibilities, women and men in this study seemed to follow the principles of equity and balanced exchange.

Authors: Vallejo Mauro Sebastián
Published: October 2020

En las últimas dos décadas del siglo XIX las neurosis y otras enfermedades nerviosas (como la neurastenia, la histeria o la debilidad nerviosa) tuvieron una marcada presencia en la cultura sanitaria de la ciudad de Buenos Aires. Esas afecciones aparecieron no sólo en la literatura médica, sino también en las publicidades de objetos y servicios destinados a combatirlas. El objetivo de este artículo es analizar, poniendo el foco en tópicos ligados al mercado, el consumo y las estrategias de publicidad, dos dimensiones de esas ofertas curativas. Por un lado, la proliferación de sustancias (tónicos, aceites y específicos) vendidas en farmacias, boticas y otros puntos de distribución. Por otro lado, el desarrollo de emprendimientos terapéuticos dirigidos por médicos y equipados con diversos implementos técnicos (centros de hidroterapia, electroterapia, gimnasia mecánica, entre otros). Los doctores se sumaron al mercado de ofertas contra las enfermedades nerviosas mediante la fundación de centros cuyos servicios también fueron promocionados como objetos de consumo a través de avisos y otros medios de difusión. El artículo intenta localizar los rasgos esenciales de ese complejo mercado, atendiendo a los actores sociales que allí intervinieron y a las tensiones y negociaciones entabladas entre ellos.

Published: October 2020

As the SARS-CoV-2 (COVID-19) pandemic spreads rapidly, there is need for a diagnostic test with high accuracy to detect infected individuals especially those without symptoms. Real-time polymerase chain reaction (RT-PCR) is a common molecular test for diagnosing SARS-CoV-2. If some factors are not taken into consideration when performing this test, it can have a relatively large number of false negative results. In this article, we discuss important considerations that could lead to false negative test reduction.

Key words: • SARS-CoV-2 • COVID-19 • Real time polymerase chain reaction • RT-PCR test • Diagnosis • False negatives • Genetics • Emerging disease

Ratings of Performance in Multisource Feedback: Comparing Performance Theories of Residents and Nurses
Authors: Tariq Muhammad , Govaerts Marjan , Afzal Azam , Ali Syed Ahsan , Zehra Tabassum
Published: October 2020

Background Multisource feedback (MSF) is increasingly being used to assess trainee performance, with different assessor groups fulfilling a crucial role in utility of assessment data. However, in health professions education, research on assessor behaviors in MSF is limited. When assessing trainee performance in work settings, assessors use multidimensional conceptualizations of what constitutes effective performance, also called personal performance theories, to distinguish between various behaviors and sub competencies., This may not only explain assessor variability in Multi Source Feedback, but also result in differing acceptance (and use) of assessment data for developmental purposes. The purpose of this study was to explore performance theories of various assessor groups (residents and nurses) when assessing performance of residents. Methods A constructivist, inductive qualitative research approach and semi-structured interviews following MSF were used to explore performance theories of 14 nurses and 15 residents in the department of internal medicine at Aga Khan University (AKU).Inductive thematic content analysis of interview transcripts was used to identify and compare key dimensions in residents’ and nurses’ performance theories used in evaluation of resident performance.Results Seven major themes, reflecting key dimensions of assessors’ performance theories, emerged from the qualitative data, namely; communication skills, patient care, accessibility, teamwork skills, responsibility, medical knowledge and professional attitude. There were considerable overlaps, but also meaningful differences in the performance theories of residents and the nurses, especially with respect to accessibility, teamwork and medical knowledge.Conclusion Residents’ and nurses’ performance theories for assessing resident performance overlap to some extent, yet also show meaningful differences with respect to the performance dimensions they pay attention to or consider most important. In MSF, different assessor groups may therefore hold different performance theories, depending on their role. Our results further our understanding of assessor source effects in MSF. Implications of our findings are related to implementation of MSF, design of rating scales as well as interpretation and use of MSF data for selection and performance improvement.

Background

Financial incentives have been used to increase physical activity. However, the benefit of financial incentives is lost when an intervention ends. Thus, for this study, we combined social network incentives that leverage the power of peer pressure with financial incentives. Few reports have examined the impact of physical activity on social capital. Therefore, the main goal of this study was to ascertain whether a combination of two incentives could lead to more significant changes in physical activity and social capital during and after an intervention.

Methods

The participants were 39 older women over 65 years of age in Kumamoto, Japan. The participants were randomly divided into a financial incentive group (FI group) and a social network incentive plus financial incentive group (SNI+FI group). Both groups underwent a three-month intervention. Measurements of physical activity and social capital were performed before and after the intervention. Additionally, the effects of the incentives on physical activity and social capital maintenance were measured six months postintervention. The financial incentive group received a payment ranging from US$4.40 to US$6.20 per month, depending on the number of steps taken during the intervention. For the other group, we provided a social network incentive in addition to the financial incentive. The SNI+FI group walked in groups of three people to use the power of peer pressure.

Results

A two-way ANOVA revealed that in terms of physical activity, there was a statistically significant interaction between group and time (p=0.017). The FI group showed no statistically significant improvement in physical activity during the observation period. In terms of social capital, the change in trust approached significance ( p =0.08).

Conclusion

Our results suggest that social network incentives, in combination with financial incentives, are more effective for promoting physical activity than financial incentives alone among older women and that these effects can continue after an intervention. In the meantime, further studies should be conducted on the effect of physical activity on social capital.

Background: To determine the carrier frequency and pathogenic variants of common genetic disorders in the north Indian population by using next generation sequencing (NGS).Methods: After pre-test counselling, 200 unrelated individuals (including 88 couples) were screened for pathogenic variants in 88 genes by NGS technology. The variants were classified as per American College of Medical Genetics criteria. Pathogenic and likely pathogenic variants were subjected to thorough literature-based curation in addition to the regular filters. Variants of unknown significance were not reported. Individuals were counselled explaining the implications of the results, and cascade screening was advised when necessary.Results: Of the 200 participants, 52 (26 %) were found to be carrier of one or more disorders. Twelve individuals were identified to be carriers for congenital deafness, giving a carrier frequency of one in 17 for one of the four genes tested (SLC26A4, GJB2, TMPRSS3 and TMC1 in decreasing order). Nine individuals were observed to be carriers for cystic fibrosis, with a frequency of one in 22. Three individuals were detected to be carriers for Pompe disease (frequency one in 67). None of the 88 couples screened were found to be carriers for the same disorder. The pathogenic variants observed in many disorders (such as deafness, cystic fibrosis, Pompe disease, Canavan disease, primary hyperoxaluria, junctional epidermolysis bullosa, galactosemia, medium chain acyl CoA deficiency etc.) were different from those commonly observed in the West. Conclusion: A higher carrier frequency for genetic deafness, cystic fibrosis and Pompe disease was unexpected, and contrary to the generally held view about their prevalence in Asian Indians. In spite of the small sample size, this study would suggest that population-based carrier screening panels for India would differ from those in the West, and need to be selected with due care. Testing should comprise the study of all the coding exons with its boundaries in the genes through NGS, as all the variants are not well characterized. Only study of entire coding regions in the genes will detect carriers with adequate efficiency, in order to reduce the burden of genetic disorders in India and other resource poor countries.

Background Long intergenic non-protein coding RNA 00342 (LINC00342) has been identified as a novel oncogene. However, the functional role of LINC00342 in colorectal cancer (CRC) remains unclear. Methods The expression of LINC00342 is detected by real-time PCR (RT-PCR) analysis. Cell proliferation, migration and invasion and xenograft model are examined to analyze the biological functions of LINC00342 in vitro and in vivo using colony formation, would healing and transwell analyses. Dual-luciferase reporter and RNA immunoprecipitation (RIP) assays are used to identify the target interactions between LINC00342, miR-19a-3p and aminopeptidase like 1 (NPEPL1). Results LINC00342 was highly expressed in CRC. Down-regulation of LINC00342 inhibited cell proliferation and metastasis of CRC cells. Moreover, knocking down LINC00342 inhibited the tumor growth in vivo. Mechanistic investigation revealed that LINC00342 might sponge miR-19a-3p to regulate NPEPL1 expression. Further investigation indicated that the ontogenesis facilitated by LINC00342 was inhibited due to the depletion of NPEPL1.Conclusion LINC00342 promotes CRC progression by competitively binding miR-19a-3p with NPEPL1.

Background: Autotetraploid rice, which is developed through chromosome set doubling using diploid rice, produces high-quality kernels that are rich in storage proteins. However, little information is available about the content of different proteins in autotetraploid rice and their proteomic analysis. Results: The dynamic changes in four storage proteins, albumin, globulin, prolamin, and glutelin, were analyzed in the endosperm of autotetraploid rice (AJNT-4x) and in that of its diploid counterpart (AJNT-2x) for comparison. The contents of the four proteins were all higher during endosperm development in AJNT-4x than in AJNT-2x, but their change and composition were almost the same in the two materials. Then, iTRAQ was employed to analyze the glutelin profiles of AJNT-4x and AJNT-2x at 10 DAF, 15 DAF, and 20 DAF. A total of 1,326 proteins were identified in AJNT-4x and AJNT-2 x using high-throughput LC-MS/MS. Among the 1,326 identified proteins, there were 362 DEPs in AJNT-4x compared with those in AJNT-2x and 372 DEPs between different development stages in AJNT-4x. Eight important upregulated proteins were identified by qRT-PCR, including B8AM24, B8ARJ0, B8AQM6, A2ZCE6, and Q40689. Among them, B8AM24 and B8ARJ0 were related to the lysine biosynthesis process. GO enrichment analysis revealed that the critical functions of DEPs exhibited little overlap between the 10, 15, and 20 DAF groups. Endosperm glutelin accumulation was regulated mainly by different DEPs during the late stage, and 15 DAF was a critical regulating point for glutelin accumulation. KEGG pathway analysis showed that ribosomal proteins were significantly higher in AJNT-4x than in AJNT-2x at 10 DAF, and the protein processing, biosynthesis, and metabolism of amino acids were higher and more active in AJNT-4x at 15 DAF, while the peroxisome was richer in AJNT-4x at 20 DAF. The PPI network showed that ribosomal proteins gradually decreased with increasing endosperm development. Conclusions: These results provide new insights into dynamic glutelin expression differences during endosperm development in autotetraploid rice, which will help in developing rice cultivars with increased yield and improved grain nutritional quality.

Background Peritoneal metastasis (PM) in gastric cancer (GC) is characterized by diffusely infiltrating and proliferating cancer cells accompanied by extensive stromal fibrosis in the peritoneal space. The prognosis of GC with PM is still poor regardless of the various current treatments. In order to elucidate the cause of difficulties in PM treatment, we compared the tumor immune microenvironment (TME) in primary and PM lesions in GC. In addition, a PM model with fibrous stroma was constructed using immunocompetent mice to determine whether its TME was similar to that in patients. MethodsImmuno-histochemical analyses of infiltrating immune cells were performed in paired primary and PM lesions from 28 patients with GC. A C57BL/6J mouse model with PM was established using the mouse GC cell line YTN16 either with or without co-inoculation of mouse myofibroblast cell line LmcMF with a-SMA expression. The resected PM from each mouse model was analyzed the immunocompetent cells using immunohistochemistry.ResultsThe number of CD8+ cells was significantly lower in PM lesions than in primary lesions (P<0.01). Conversely, the number of CD163+ cells (M2 macrophages) was significantly higher in PM lesions than in primary lesions (P=0.016). Azan staining revealed that YTN16 and LmcMF co-inoculated tumors were more fibrous than tumor with YTN16 alone (P<0.05). Co-inoculated fibrous tumor also showed an invasive growth pattern and higher progression than tumor with YTN16 alone (P=0.045). Additionally, YTN16 and LmcMF co-inoculated tumors showed lower infiltration of CD8+ cells and higher infiltration of M2 macrophages than tumors with YTN16 alone (P<0.05, P<0.05). These results indicate that LmcMF plays as cancer-associated fibroblasts (CAFs) by crosstalk with YTN16 and CAFs contribute tumor progression, invasion, fibrosis, and immune suppression.ConclusionsThis model is the first immunocompetent mouse model similar to TME of human clinical PM with fibrosis. By using this model, new treatment strategies for PM, such as anti-CAFs therapies, may be developed.
