Nostos, nostalgia y el mundo como teatro en la narrativa de Luisa Josefina Hernández
Authors: Gutiérrez Hibler Jonathan 
Published: July 2023

La obra narrativa de Luisa Josefina Hernández tiene marcas de su otro proceso artístico: el teatro. El presente trabajo analiza fragmentos de tres novelas de la autora donde la influencia del teatro dialoga con los temas del nostos y la nostalgia. En La plaza de Puerto Santo (1961), Nostalgia de Troja (1970) y Apocalipsis cum figuris (1981), están presentes dichos temas, pero se usan recursos dramáticos desde la perspectiva de los narradores y de los personajes. Además, el teatro está presente como parte de la vida y esto se extiende a un tercer tema presente desde los clásicos grecolatinos: Theatrum mundi. Los seres humanos somos como personajes dentro de una obra teatral.
Durante el análisis se encontró el uso de diálogos, monólogos y elementos metaliterarios en diferentes situaciones. Así mismo, la autora noveliza géneros propios del teatro dentro de la novela, como sucede con la comedia de enredos, las pastorelas y el teatro alegórico. La distancia temporal que hay entre las tres novelas permite observar una evolución en la narrativa de la autora mediante el uso de los elementos teatrales. Los regresos o viajes de los personajes ocurren en dos dimensiones: una física y la otra psicológica. Además de esto, el nostos como tema no implica un éxito como sucede en la Odisea y la nostalgia puede variar en lo temporal: pasado, presente, futuro y en lo Absoluto.
The Notion of Urban Cultural Landscape Concept From Landscape Architecture Perspective
Authors: Rosmalia Dini , Martokusumo Widjaja 
Published: July 2023

Urban cultural landscape is a concept considered as new and still raises many arguments among scholars. This concept comes from terms of cultural landscape and first was revealed in 1925 by Sauer, a Geographer. Then this term has evolved to be a concept of urban cultural landscape after finding many countries in the world are interesting to propose their historic cities as a World Heritage Cultural Landscape. Currently, some researchers from geography, anthropolo-gy, economics, architecture and landscape architecture have tried to reveal the concept. However, generally the description of their concept is more in processing or exploring the establishment elements of urban cultural landscape, so as can be seen that the concept is not comprehensive yet and still partial in accordance with the scientific background. Therefore, this paper aims to reveal the concept of urban cultural landscape from different disci-plines to gain a comprehensive one. And to support the establishment of the concept, the paper uses a case study, which is Cirebon city as it is one of the unique and historic cities in Indonesia. The city has been established since 15th century. The establishment has been affected by social, cultural, political and economic impacts from various periods of rules (Sultanate Cerbon, Dutch Colonial and the Republic of Indonesia).of rule (Sultanate Cerbon, Dutch Colonial and the Republic of Indonesia).

Published: July 2023

Background: A systemic metabolic disorder by insulin resistance, type-2 diabetes mellitus (T2DM), is characterised by an increased level of reactive oxygen species (ROS) and decreased superoxide dismutase (SOD), which is associated with the activation of proinflammatory cytokine pathways such as tumor necrosis (TNF)-α. This condition usually stimulates inflammation of the periodontal tissue (periodontitis). Vitamin-D3 can inhibit the release of inflammatory mediator and reduce the risk of chronic periodontitis. Purpose this study to determine the effect of the secretome-hypoxia mesenchymal-stem-cells (SH-MSCs)-Vitamin-D3 combination on the expression of SOD, IL-10, and TNF-α genes in T2DM periodontitis-induced rats.
Method: 30 rats were randomly divided into five groups; normal sham condition, positive control, SH-MSCs group, vitamin-D3 group, and combination of SH-MSCs and vitamin D3 group. SH-MSCs were injected at doses of 150 uL in the gingival. In addition, vitamin D3 5000 IU 2.25 mcg were administrated orally. After 35 days, all rats were sacrificed, and qRT-PCR from gingival tissue was performed to identify the expression of SOD, IL-10 and TNF-α genes

Published: July 2023

Background: Most of dental implants are accompanied by guided bone regeneration (GBR) procedures. Collagen membrane which is the most widely used type of membrane in the GBR procedure has the disadvantage of not having antimicrobial properties, old bone formation, easy to tear, and soft so that it does not maintain the dimensions of the augmentation area. Bombyx mori L. fibroin has good mechanical properties and has the potential to be used as a pharmaceutical material that is biocompatible, antimicrobial, and stimulates bone growth. The aim of this study was to analyze the effect of Bombyx mori L. fibroin coating on the mechanical properties of collagen membranes.
Method: The samples consisted of the control group (group A) and the treatment group, the collagen membrane was coated using the Bombyx mori L dip-coating fibroin technique, namely group B (1 time coating process), group C (2 times coating process) and group D (3 times the coating process).

Published: July 2023

Background: Median Rhomboid Glossitis (MRG) is included in the group of nodular-plaque-like candidiasis, a subtype of chronic hyperplastic candidiasis. A lot of literature suggests that MRG is a manifestation of Diabetes Mellitus (DM), but the association between DM and MRG is unclear until now. This article reports an MRG found in an undiagnosed diabetes mellitus patient.
Case: In October 2019, A 71-year-old man came to RSGM Universitas Jember to fix his loose denture. In the oral examination, we found a well-bordering, atrophic oval area surrounded by thick- soft white plaque. In his leg, we found itchy papule, ulcer, and crust multiple lesions. The microscopic examination of the white plaque swab showed that the spore and hyphae were found to fill all fields of view. The direct sugar blood level test showed that the sugar blood level was 390 mg/dL. We diagnosed the patient as having an MRG associated with suspected DM.
Case Management: The patient was given miconazole oral gel and recommended to use it after cleaning the tongue three times a day. For diabetes management, the patient was referred to the Unit Medical Center University of Jember. The patient was diagnosed with diabetes mellitus and given oral-antidiabetics. After two weeks, the atrophic area had improved, and the white plaque had disappeared.
Conclusion: General practitioners must be aware if they find the MRG in their patients caused a probability of underlying undiagnosed systemic disease, particularly diabetes mellitus on them.

Published: July 2023

Background: Orthodontic treatment is performed to correct the malocclusion, and after treatment is complete. The position of the teeth must be maintained because the teeth can move back to their original position, commonly known as relapse. Various attempts have been made, such as using retainers, and various studies have used pharmacological agents such as bisphosphonate risedronate to inhibit relapse, but these studies still used the injection method, which is inconvenient to apply and has a systemic effect. For this reason, changing the bisphosphonate preparation to an emulgel will facilitate its application and have a local effect, but it is necessary to test and determine its effectiveness in inhibiting the relapse.
Method: An experimental laboratory study was conducted on 18 guinea pigs, which were divided into three groups: I (control), II (emulgel without risedronate), and III (emulgel with risedronate). The teeth were moved with open coil springs on both lower incisors for seven days, stabilized for seven days, and emulgel applied in groups II and III. The coil spring was removed, and the distance between the two incisors was measured on the third and seventh days.
Result: Using One-Way ANOVA and Post Hoc LSD, the data analysis results showed significant differences between the control and the risedronate emulgel groups on the third and seventh days. The largest relapse occurred in the control group, while the smallest was in the emulgel group with risedronate.
Conclusion: These results indicate that risedronate bisphosphonate in the form of emulgel influences inhibiting the movement of tooth relapse
