Background

Epidemiological data of cephalosporin-resistant Enterobacterales in Sub-Saharan Africa is still restricted, and in particular in Mozambique. The aim of this study was to detect and characterize extended-spectrum β-lactamase (ESBL) - and plasmid-mediated AmpC (pAmpC)-producing clinical strains of Escherichia coli at Maputo Central Hospital (MCH), a 1,000-bed reference hospital in Maputo, Mozambique.

Methods

A total of 230 clinical isolates of E. coli (n=230) from urine (n=199) and blood cultures (n=31) were collected at MCH during August-November 2015. Antimicrobial susceptibility testing was performed by the disc diffusion method and interpreted according to EUCAST guidelines. Isolates with reduced susceptibility to 3rd generation cephalosporins were examined further; phenotypically for an ESBL-/AmpC-phenotype by combined disc methods and genetically for ESBL- and pAmpC-encoding genes by PCR and partial amplicon sequencing as well as genetic relatedness by ERIC-PCR.

Results

A total of 75 isolates with reduced susceptibility to cefotaxime and/or ceftazidime (n=75) from urine (n=58/199; 29%) and blood (n=17/31; 55%) were detected. All 75 isolates were phenotypically ESBL-positive and 25/75 (33%) of those also expressed an AmpC-phenotype. ESBL-PCR and amplicon sequencing revealed a majority of blaCTX-M (n=58/75; 77%) dominated by blaCTX-M-15. All AmpC-phenotype positive isolates (n=25/75; 33%) scored positive for one or more pAmpC-genes dominated by blaMOX/FOX. Multidrug resistance (resistance ≥ three antibiotic classes) was observed in all the 75 ESBL-positive isolates dominated by resistance to trimethoprim-sulfamethoxazole, ciprofloxacin and gentamicin. ERIC-PCR revealed genetic diversity among strains with minor clusters indicating intra-hospital spread.

Conclusion

We have observed a high prevalence of MDR pAmpC- and/or ESBL-producing clinical E. coli isolates with FOX/MOX and CTX-Ms as the major β-lactamase types, respectively. ERIC-PCR analyses revealed genetic diversity and some clusters indicating within-hospital spread. The overall findings strongly support the urgent need for accurate and rapid diagnostic services to guide antibiotic treatment and improved infection control measures.

Authors: Wang Gu Heng , Mao Tian , Xing Shu Guo , Chen Ya Lan , Zhang Yu Xuan , Xie Ren Guo
Published: July 2019

Background

To evaluate the effective and safety of reconstruction of flexor and extensor tendon in hand using allogenic tendon with 2- to 7.6-year fellow-up.

Methods

Between August 2007 and July 2014, we performed tendon allografts for 14 patients who suffered from severe hand injury with 2 or more tendon defects. 10 patients have been followed-up, 6 cases of flexor tendon rupture with defect, 3 cases of extensor tendon rupture with defect, 1 case with flexor and extensor tendon rupture with defect. Tendon allografts were used to repair tendon defects in order to reconstruct the function of flexion or extension. At the final follow-up visit, the total active motion (TAM), grip strength, pinch strength, DASH and the degree of satisfaction were measured. The WBC, C-reactive protein (CRP), Erythrocyte sedimentation rate (ESR), Total T cell and CD4+T/CD8+T were measured to evaluate the response related to immune and infection.

Results

The average follow-up period was 50.0 months (range 24-82 months). The mean motion of TAM was 129.9°(rang 12-259°), pinch strength was 0.76Kg (rang 0-4.5Kg), grip strength was 18.67Kg (rang 4-46Kg), the score of DASH was 14.25 (rang 3.3-30.8), 7 patients were satisfied and 3 patients were partially satisfied with the results. The results of WBC, CRP, ESR, Total T cell and CD4+ T/CD8+ T were mostly in normal field.

Conclusion

In severe hand injuries with multiple tendon defects, reconstruction of flexor and extensor tendon in hand using allogenic tendon is an effective and safe treatment.
Histological, radiological and clinical outcomes of sinus floor elevation using lateral approach pre-/post- extraction of the severe periodontally compromised maxillary molars: a split-mouth randomized clinical trial
Authors: Yue Zhaoguo , Liu Qi , Zhang Haidong , Yang Jingwen , Zhan Yalin , Han Ye , Yan Yue , Miao Lili , Huang Wenxue , Zhang Churen , Hou Jianxia
Published: July 2019

Background

Residual alveolar bone volume is a critical factor for the dental implants’ survival [1]. When the volume of alveolar bone in the posterior maxillary region is less than 4mm, the maxillary sinus floor elevation (MSFE) with lateral approach is an effective way to solve this problem [2]. Traditionally, this standard approach is usually delivered 4 months after the extraction of the tooth. However, the defective dentition due to the extraction would cause impaired masticatory function during the long period of the bone regeneration, especially when molars on both sides are severely periodontal compromised and need to be extracted. So, as periodontists, we start to wonder if we can maintain a compromised tooth so that we perform the sinus floor elevation before the extraction (the modified MSFE) to take fully advantage of residual strength of the teeth.

Methods/Design

The proposed study is designed as a prospective single-center, split-mouth design, randomized controlled trial. We plan to recruit 10 patients whose molars on both sides are severely periodontal compromised and in need of dental implant treatment in the atrophied posterior maxilla. The two sides of each patients will be divided into two groups randomly using Randomizer for Clinical Trials (Institute for Medical Informatics, Statistics and Documentation, Medical Univ. Graz). Test group: sinus floor augmentation before tooth extraction (the modified MSFE); Control group: sinus floor augmentation after tooth extraction (the standard MSFE). Implant survival rates, mucosal conditions around the implants, complications, treatment time and postoperative discomfort (visual analogue scale for intraoperative pain and postoperative pain/discomfort) will be recorded. The volume of the alveolar bone will be measured 6, 12, 18, and 24 months after the MSFE surgery by means of CBCT. Histological and histomorphometic analysis will be performed on biopsies retrieved from both side of grafting sites.

Discussion

The current study will explore the effectiveness of the modified MSFE on minimizing the discomfort period caused by defected dentition. To determine whether the modified MSFE will promote the grafting outcomes, the quality and the quantity of the osteogenesis on the sinus floor will also be compared. Depending on the result of the current study, we will determine all the protocols and details about the modified MSFE, including indications, detailed methods, post-operational complications and managements.

Published: July 2019

Background

We present a study of the etiological factors and clinical features of classic fever of unknown origins (FUO) to provide evidence for related clinical diagnosis and treatment.

Methods

We analyzed 1,641 cases of patients with classic FUO hospitalized in West China Hospital of Sichuan University during January 1, 2011 and December 31, 2017, analyzed the etiological factors of classic FUO, explored and screened the laboratory indicators related to infectious diseases, and compared the above data with the clinical features of tuberculosis and lymphoma, which are difficult to diagnose.

Results

1,504 patients were diagnosed through various examination or diagnostic treatment methods, and the diagnosis rate was 91.65%. 48.69% (799) were infectious diseases, of which tuberculosis was the most common, accounting for 19.50% (320) . 19.26% (316) were connective tissue diseases, among which adult-onset Still’s disease (AOSD) was the most common, accounting for 5.42%(89). 16.94% (278) were neoplastic diseases, and lymphoma was the most common malignant tumor, accounting for 8.71%(143). 6.76% (111) were other diseases; and 8.35% (137) were unclear. We found that there were no significant differences between the symptoms, signs, and non-specific routine examination results of tuberculosis and lymphoma. Tuberculosis-related examinations and pathological examinations used more frequently.

Conclusion

The causes of classic FUO are mostly infectious diseases, in which tuberculosis accounts for a large proportion. Non-infectious diseases that cause FUO are mainly connective tissue diseases and malignant tumors. Tuberculosis and lymphoma are relatively difficult to diagnose. The causes of most cases of classic FUO could be ascertained.
Intestinal DCs global gene expression dynamics affected by recombinant baker’s yeasts saccharomyces cerevisiae
Authors: Han Baoquan , Zhang Tingting , Li Xinyi , Zhao Rui , Ge Wei , Mu Lu , Xu Kun , Zhang Zhiying
Published: July 2019

Background

The baker’s yeast, saccharomyces cerevisiae, has been widely used throughout our daily life in diverse aspects for thousands of years. The saccharomyces cerevisiae was found to specifically target the dendritic cells (DCs) in mammalian with a manner of antigen-receptor interaction as described previously. It is necessary to investigate the effect of the baker’s yeasts on global gene expression dynamics of intestinal DCs and explore the possibilities of using baker’s yeast as gene delivery vehicle to modulate animal’s immune functions

Results

with a murine oral delivery model in vivo, we confirmed the feasibility of using budding yeast as gene delivery vehicle to the intestinal DCs using the Western blots. We then examined the transcriptome profile of the mouse intestinal DCs upon yeast stimulus. The enrichment analysis of unique transcripts indicated the beneficial role of yeast in modulating the DC-mediated adaptive immunity. Compared with previous study, we also found that a large fraction of the regulated genes is coincident with the response induced by other fungus, suggesting that the budding yeast induces a similar tailored unique genetic re-programming of DCs. Another analysis of transcriptome profile indicated that expression of β-catenin gene significantly changes DCs gene expression related to inflammatory response and cell adhesion.

Conclusions

Here, we defined the role of budding yeast on global gene expression of intestinal DCs, and confirmed the important role of β-catenin gene on the DCs-related inflammatory response, which provides a framework for the development of mucosa yeast-based DNA vaccine.

Authors: Gracia Granados Marlon Efraín
Published: July 2019

El lavado de activos es un delito que trae consigo un gran número de consecuencias negativas a la sociedad en general. Para mitigar este problema en las entidades financieras, que es donde principalmente se presenta, se han desarrollado sistemas anti lavado de dinero. Lo anterior origina un nuevo problema: los falsos positivos que se obtienen a partir de dichos sistemas, los cuales representan para las entidades financieras pérdidas de dinero, tiempo y foco, al no tratar las verdaderas operaciones inusuales. Se evalúan los principales métodos de detección de operaciones inusuales de lavado de activos que se encuentran en la literatura, para determinar cuáles técnicas ofrecen los mejores resultados y a partir de estas generar un nuevo modelo que mejore los indicadores registrados. A partir de un proceso de revisión y replicación de metodologías de detección de anomalías encontradas en la literatura, se pudo generar un nuevo modelo que presenta mejores métricas a la hora de clasificar operaciones como normales e inusuales, lo cual puede representar para las entidades financieras una manera de disminuir las tasas de falsos positivos en sus sistemas anti lavado.

Clinical urine test with the correct interpretation can help the clinician in the diagnosis of the urinary system diseases, as well as other organs and systems. Most laboratories in medical institutions are currently switching to an automated urinary sediment test, but microscopy appears relevant. Unfortunately, clinicians often interpret only three or four (most often proteinuria, leukocyturia and erythrocyturia) of all the numerous indicators of urine test, unfairly ignoring the others. The urinary cylinders are one of these important elements of the urinary sediment. The article presents the characteristics of the main types of urinary cylinders, their origin, composition, morphology and clinical significance.

Photodynamic diagnosis is a promising method in the treatment of laryngeal papillomatosis, which includes an assessment of the increased visual and spectrometric contrast of papillomatosis masses against the background of the introduction of the photosensitizer. We have developed a method of treatment of laryngeal papillomatosis in two stages: intraoperative diagnosis using the domestic preparation of 5-aminolevulinic acid hydrochloride and subsequent surgical treatment using a carbon dioxide laser. Using the new method, we treated 21 patients, of which 13 (61.9%) had the inter-recurrent period longer than 12 months.

Interventions to Structural System of Masonry Buildings and their Effects to their Seismic Response
Authors: Karantoni Fillitsa V. , Sarantitis Dimitris N.
Published: July 2019

Background:

Preservation of listed buildings, depending on the importance of each one, requires the conservation of the whole structure or of only the external walls, often called shell of the building, or even only of the façade. In the latter cases, although the new structure is studied to undergo the applied loads according to the codes in force, less research is made to study the response of the remaining structure under seismic loads.

Objective:

The response of unreinforced masonry (URM) structures with alterations of the original load bearing system to strong ground motions is studied in the present paper. Commonly used radical interventions comprise the addition of a steel or reinforced concrete frame in the interior of the structure after removal of interior load bearing or/and dividing walls. The embedded substructure is designed to support the functional loads of the building and commensurate seismic design forces associated with its mass. In this setting, perimeter walls are relieved of any bearing action apart from resisting the state of stress associated with their self-weight. An important design decision is the extent of contact and interaction that is allowed to occur between the perimeter URM walls and the interior structural system; both options present advantages and disadvantages.

Methods:

The effect that this design option has on the seismic response of the composite system is studied in this paper using linear elastic finite element analysis. The effect of each intervention is estimated by comparing the principal tensile stresses (pts) developed on the walls before and after each intervention as well as the percentage of the wall areas in elevation where the pts are higher than tensile strength of masonry.

Results:

It is found that connection of the frame to the masonry walls at several points around the floor and roof perimeters creates a diaphragm action that effectively reduces the out-of-plane bending of the self-standing perimeter URM walls without excessive local stress intensities and increases the shear strength of the building. Lack of contact between the old and new load bearing elements leads to higher intensity stresses due to bending and only the addition of a reinforced concrete tie belt at the top of the walls may mitigate serious damage.

Conclusions:

The cooperation of the Moment Resisting Frames, irrespective of the material of the frame (reinforced concrete or structural steel) and the walls by connecting the perimeter structural walls with it at floor and roof levels, is more efficient to the stress state of the walls transforming the critical out-of-plane bending of later to shear one, preventing them from out-of-plane collapse.
Artificial Intelligence Versus Clinicians in Disease Diagnosis: Systematic Review
Authors: Shen Jiayi , Zhang Casper J P , Jiang Bangsheng , Chen Jiebin , Song Jian , Liu Zherui , He Zonglin , Wong Sum Yi , Fang Po-Han , Ming Wai-Kit
Published: July 2019

Background

Artificial intelligence (AI) has been extensively used in a range of medical fields to promote therapeutic development. The development of diverse AI techniques has also contributed to early detections, disease diagnoses, and referral management. However, concerns about the value of advanced AI in disease diagnosis have been raised by health care professionals, medical service providers, and health policy decision makers.

Objective

This review aimed to systematically examine the literature, in particular, focusing on the performance comparison between advanced AI and human clinicians to provide an up-to-date summary regarding the extent of the application of AI to disease diagnoses. By doing so, this review discussed the relationship between the current advanced AI development and clinicians with respect to disease diagnosis and thus therapeutic development in the long run.

Methods

We systematically searched articles published between January 2000 and March 2019 following the Preferred Reporting Items for Systematic reviews and Meta-Analysis in the following databases: Scopus, PubMed, CINAHL, Web of Science, and the Cochrane Library. According to the preset inclusion and exclusion criteria, only articles comparing the medical performance between advanced AI and human experts were considered.

Results

A total of 9 articles were identified. A convolutional neural network was the commonly applied advanced AI technology. Owing to the variation in medical fields, there is a distinction between individual studies in terms of classification, labeling, training process, dataset size, and algorithm validation of AI. Performance indices reported in articles included diagnostic accuracy, weighted errors, false-positive rate, sensitivity, specificity, and the area under the receiver operating characteristic curve. The results showed that the performance of AI was at par with that of clinicians and exceeded that of clinicians with less experience.

Conclusions

Current AI development has a diagnostic performance that is comparable with medical experts, especially in image recognition-related fields. Further studies can be extended to other types of medical imaging such as magnetic resonance imaging and other medical practices unrelated to images. With the continued development of AI-assisted technologies, the clinical implications underpinned by clinicians’ experience and guided by patient-centered health care principle should be constantly considered in future AI-related and other technology-based medical research.
Media Use Among Students From Different Health Curricula: Survey Study
Authors: Zupanic Michaela , Rebacz Patrick , Ehlers Jan P
Published: July 2019

Background

Mobile devices such as smartphones, tablets, and laptop computers enable users to search for information and communicate with others at any place and any time. Such devices are increasingly being used at universities for teaching and learning. The use of mobile devices by students depends, among others, on the individual media literacy level and the curricular framework.

Objective

The objective of this study was to explore whether there were differences in media use in students from various curricula at the Faculty of Health, Witten/Herdecke University.

Methods

During the 2015-16 winter term, a survey was conducted at the Faculty of Health, Witten/Herdecke University, in which a total of 705 students (out of 1091 students; response rate: 705/1091, 64.61%) from 4 schools participated voluntarily: medicine (346/598), dentistry (171/204), psychology (142/243), and nursing science (46/46). The questionnaire developed for the study included 132 questions on 4 topics: (1) electronic and mobile devices (19 questions), (2) communication and organization of learning (45 questions), (3) apps/programs/websites/media (34 questions), and (4) media literacy (34 questions). The questionnaire was distributed and anonymously completed during in-class courses.

Results

Students from all 4 schools had at least two electronic devices, with smartphones (97.4%, 687/705) and laptops (94.8%, 669/705) being the most common ones. Students agreed that electronic devices enabled them to effectively structure the learning process (mean 3.16, SD 0.62) and shared the opinion that university teaching should include imparting media literacy (mean 2.84, SD 0.84). Electronic device ownership was the highest among medical students (mean 2.68, SD 0.86) and medical students were the only ones to use a tutorial (36.1%, 125/346). Dental students most widely used text messages (mean 3.41, SD 0.49) and social media (mean 2.57, SD 1.10) to organize learning. Psychology students considered mobile devices to be most ineffective (mean 2.81, SD 0.83). Nursing science students used emails (mean 3.47, SD 0.73) and desktop computers (39%, 18/46) most widely.

Conclusions

The results show that almost all students use electronic learning (e-learning) tools. At the same time, different profiles for different degree programs become apparent, which are to be attributed to not only the varying curricula and courses but also to the life circumstances of different age groups. Universities should, therefore, pay attention to the diverse user patterns and media literacy levels of students when planning courses to enable successful use of e-learning methods.

As produções originais Netflix têm seu espaço demarcado na indústria audiovisual. Nesta pesquisa damos destaque aos produtos que trazem elementos ou estórias já apresentados ao público anteriormente, os remakes, as adaptações e/ou as continuações. A empresa explora nessas produções a memória, a nostalgia e a história a partir de um “público base”, ou seja, um telespectador que já conhece e tem interesse no produto. Nesse cenário, compreendemos essa prática a partir do conceito de safe returns (HOLDSWORTH, 2011), o retorno seguro, para pensar as produções audiovisuais dentro da condição de valor econômico da nostalgia. Trazemos, então, o revival da série Gilmore Girls, que foi lançado na plataforma de streaming em 2016, como exemplo de um investimento safe returns da Netflix. Palavras-chave: Séries. Netflix.

Published: July 2019

A questão do processo judicial de adoção de crianças por casais homossexuais perpassa por diversas questões sociais. Envolve aspectos legais, culturais, que ultrapassam os limites simbólicos, e que transcorrem sobre questões jurídicas e étnicas, envolvendo questionamentos e enfrentamentos. Tem-se, explicitamente ou implicitamente, fronteiras étnicas que marcam o lugar de cada sujeito na sociedade, especificamente, por envolver a sexualidade, a homossexualidade, os “novos” conceitos de família, os questionamentos sociais, religiosos, filosóficos e jurídicos quanto à questão. Os “novos” arranjos familiares, posto à etnicidade, a sociedade, em razão de diversas transformações, reorganiza-se e recria-se a família. Destarte, o presente trabalho investigou como e em que medida os marcadores étnicos e sociossexuais de casais homossexuais interferem, influenciam ou se apoiam nas decisões judiciais para a adoção de crianças em Jequié, Ilhéus e Vitória da Conquista, no Estado da Bahia, tendo como colaboradores juízes que acompanharam os mencionados pedidos de adoção e os casais que pretenderam realizar a adoção de crianças. Pensar como os discursos funcionam é colocar-se na encruzilhada de um duplo jogo da memória: o da memória institucional que estabiliza, cristaliza, e, ao mesmo tempo, o da memória constituída pelo esquecimento que é o que torna possível o diferente, a ruptura, o outro. Com a análise de dados sociológicos dos grupos envolvidos, a pesquisa apresentou alguns marcadores étnicos e sociossexuais de casais homossexuais como possíveis razões das decisões judiciais para a adoção de crianças pelos casais gays.

A Comparative Study of Rural Entrepreneurial Challenges: Towards Rural Economic Development and a Policy Framework
Authors: Agbenyegah Albert Tchey
Published: July 2019

The primary purpose of this rural study was to compare the challenges that impede successful operations of entrepreneurial activities and small businesses. Through quantitative design, a seven-point Likert-scale questionnaire was utilized to gather primary data. Two sampling techniques, namely simple random and purposive, were applied to select the research participants. Based on a Likert spectrum, 267 questionnaires were administered to SME owners by the researcher, assisted by two research trainees. These questionnaires were ranked from (1) strongly disagree to (7) strongly agree. Two main questions, which provided guidance to this study, were certified reliable by the Cronbach alpha coefficient of 0.768 and 0.976. Data analysis was possible through the descriptive and inferential tools supported by the independent t-test, Pearsonâ€™s chi-square test, and cross-tabulation. The final outcomes demonstrate higher levels of challenges in the Frances Baard (FB) District than in the John Taolo Gaetsewe (JTG) District. This implies that owner-managers of small businesses in the FB District experienced more challenges in operating their businesses. The study recommends SME Policy Framework (SPF) training and intensifying the existing processes of monitoring after training to justify the owner-managersâ€™ moral commitments.

Effects of drying methods on the vitamin and provitamin compositions of
selected vegetables during storage were assessed in this study. Telfaria
occidentalis, Celosia argentea (green), Vernonia amygdalina, Moringa
oleifera, Launaea taraxacifolia, Curcubita maxima and Celosia argentea (red)
were subjected to air drying (AD), oven drying (OD) and freeze drying (FD).
The experiment was a 3x7 factorial arrangement in a completely randomized
design. Dried leaves were milled and assayed for vitamins (pyridoxine,
riboflavin, ascorbic acid and tocopherol) and provitamins (total carotene
and ergocalciferol). Samples were stored in opaque airtight containers after
drying and assayed periodically at weeks 0, 3, 6, 9, 12, 15 and 18 of
storage. Air-dried samples had significantly higher (P<0.05) total carotene
(1177.49 ?g/100g), pyridoxine (0.59 mg/100g), riboflavin (0.46 mg/100g),
ascorbic acid (39.11 mg/100g), ergocalciferol (46.55 ?g/100g) and tocopherol
(57.52 ?g/100g) compared with samples dried by other methods. Moringa
oleifera leaf type had significantly higher (P<0.05) total carotene (1079.48
?g/100g), riboflavin (0.41 mg/100g), ergocalciferol (46.40 ?g/100g) and
?-tocopherol (58.45 ?g/100g) while Cucurbita maxima had significantly higher
(P<0.05) pyridoxine (0.73 mg/100g). Effects of the interaction of drying
methods and leaf type were significant (P<0.05) on the vitamin and
provitamin compositions of samples. The effect of the interaction of the
oven drying method and leaf type was highly significant (P<0.05) on inherent
vitamin and provitamin of samples. Vitamin and provitamin compositions of
samples were stable until week six. Air-dried samples contained more
vitamins and provitamins which were also more retained in storage.

Instagram Fenomenlerinin Paylaşımları Üzerinden Göstergebilimsel Bir İnceleme
Authors: Birol Murat , Bakır Zeynep Nihan
Published: July 2019

Bugün insanlar
sosyal medya hesaplarından genellikle sosyal yaşantılarına dair görseller
paylaşmaktadırlar. Bu görsellerin yoğun olarak paylaşıldığı Instagram
uygulaması ise insanların mobil taşınabilir cihazlarında (Akıllı telefon,
tablet bilgisayar vb.) günlük yaşam pratiklerinden örnekler sergilemektedir.
Diğer sosyal ağlardan farklı olarak kişiler kimliklerine yakın hissettikleri ya
da takip ettiğinde yaşantısından haz duyabileceği kişileri takip ederek
popülerleşme yoluna gitmektedir. Böylelikle popüler hale gelen internetteki
sosyal ağ öncüleri ya da fenomenler, belirli bir kitleye kendi kullandıkları
ürünler ya da birtakım yaşam tarzlarına dayalı uygulamalarla yol göstermekte,
onları etkisi altına almaktadır. Karşılıklı etkileşimin de kurulduğu bir
hayran-aktör/aktris oyununa dayalı bu sanal mecrada diğer ağlarda pek
rastlanılmayan ya da bu denli belirginleşmeyen belirli bir Instagram kültürü
yaratılmıştır. Kullanıcı bireyler, paylaşılan görsellere kodlanan anlamlar ile
fenomenler aracılığıyla iletişim kurarak kendi kimliklerini ya da sanal
kimliklerini bu kişilerin belirledikleri yöntemlerle –tarz geliştirerek-
yeniden dönüşüme sokmaktadır. Bu da kimliğin sanallaşması ya da sanal bir
gerçeklik yaratılması kavramlarını gündeme taşımaktadır. Buradan hareketle
çalışmada, sosyal medya üzerinden Instagram uygulamasındaki fenomenler
incelenerek paylaşımda bulundukları görseller analiz edilmeye çalışılmıştır.
Çalışmada ele alınan görseller Roland Barthes’ın göstergebilimsel çözümleme
metoduyla kaleme alınmıştır. Çalışmanın sonucunda, fenomenlerin çeşitli
paylaşımları üzerinden insanları görsel unsurlar kullanarak nasıl etkilediği ve
görsellerine kodlanan anlamların da birbiriyle nasıl etkileşimde bulunduğu
karşılaştırılarak tespit edilmiştir.
Intersticios de la posmodernidad en el manga mexicano Drem
Authors: Castelli Olvera Sarahi Isuki
Published: July 2019

Introducción. En este artículo se analiza el manga[1] mexicano Drem, creado y publicado en México en 2008 por la diseñadora Lorena Velasco Terán. Se parte del supuesto de que Drem es una historieta mexicana en cuyo argumento se ve presente la posmodernidad como dominante cultural, aun cuando conserva rasgos de la narrativa moderna. Objetivo. Analizar la iconografía y gráfica del manga mexicano Drem para identificar los elementos propios de la modernidad y posmodernidad presentes en la narrativa visual y escrita. Método. Análisis de la imagen basado en el paradigma de inferencias indiciales de Carlo Ginzburg, por medio del cual se identificaron detalles en la gráfica de la fuente primaria para después rastrear sus referentes históricos y culturales. Finalmente, se analizan dichos referentes por medio de las propuestas de Jameson y García Canclini. Resultados. La narración retoma elementos del cuento fantástico moderno y del posmoderno, los cuales se entremezclan y separan por momentos. Del cuento fantástico moderno, la narración retoma el sueño y el psicoanálisis para ubicar lo sobrenatural en el interior del sujeto. Del cuento fantástico posmoderno, la narración emplea la multiplicidad del yo del sujeto, el fenómeno religioso intercalado con lo psicoanalítico, la ruptura espacial y temporal. Conclusiones. En este manga mexicano la posmodernidad se presenta como dominante cultural en los primeros seis volúmenes; en el último predomina la modernidad. Drem es un producto creado en un contexto en el que el diálogo entre los diferentes productos gráficos de culturas lejanas y distantes se acentúa y da paso a creaciones nuevas donde la fragmentación y las mezclas espaciales-temporales son constantes en narrativas que se traslapan y rompen como reflejo del mundo posmoderno creado por las borrosas fronteras actuales.
