Published: July 2020

Objectives: To discuss the prevention and containment of COVID-19 at a general hospital in Shenzhen China; to analyze the epidemiological and clinical characteristics of its confirmed patients, which is intended to provide a model for other hospitals in COVID-19 management.Methods: The General Hospital of Shenzhen University sets up 4 medical zones relative to the COVID-19 prevention and containment. In so doing, the suspected patients classified into different kind of ward receive different treatment (Classified and Separated Treatment). The epidemiological distribution and clinical characteristics of 28 confirmed cases in the hospital were analyzed.Results: There are no medical personnel infected cases, no cross-infection among the patients in the hospital, and no misdiagnosis or missed diagnosis of COVID-19. The majority of cases in the group is from 15 to 60 years old, 25 cases had a definite travel history or close contact history in the epidemic area, and parents and spouses of the confirmed patients are the main contact groups. Fever and respiratory symptoms have a high proportion, 4 diarrhea and 4 asymptomatic cases. Additionally, the decrease of lymphocyte is observed in 8 cases. Chest CT scan shows viral pneumonia in 14 cases，All patients were confirmed by nucleic acid tests.Conclusions: Classified and Separated Treatment facilitates management of COVID-19 in the general hospital. Relative to suspected patients in the general hospital, diagnosis matters more than treatment. Epidemiological history, lymphocyte count, and chest CT scan play an important role as the indicator in early diagnosis of COVID-19.

Background

Research landscapes and quality may change in many ways. Much research waste has been increasingly reported. Poorly conducted clinical and biomedical researches are detrimental to the health of the people and healthcare performance with misleading clinical evidence. Efforts to improve research performance will need good data on the profiles and performance of past research. This systematic review aims to describe the characteristics and examine the quality of clinical and biomedical research in Malaysia and Indonesia.
Methods

A search will be conducted in PubMed, EMBASE, CINAHL and PsycINFO to identify for published clinical and biomedical research from 1962 to 2019 from Malaysia and/or Indonesia. Additional search will also be conducted in MyMedR (Malaysian only). Studies found will be independently screened by a team of reviewers, relevant information will be extracted and the quality of articles will be assessed. In Phase 1, the characteristics of the research including the profiles of the researchers and the journals in which they are published will be reported descriptively. In Phase 2, a research quality screening tool will be validated to assess the research quality based on three domains of relevance, the credibility of the methods and usefulness of the results. Associations between the research characteristics and quality will be analysed. The independent effect of each of the determinant will be quantified in multivariable regression analysis. Longitudinal trends of the research characteristics, health conditions studied and settings, among others will be explored.
Discussion

Results of this study will serve as the 'baseline' data for future evaluation and within the country and between countries comparison. This review may also provide informative results to stakeholders of the evolution of research conduct and performance from the past until now. The longitudinal and prospective trends of the research characteristics and quality could provide suggestions on improvement initiatives. Additionally, information on health conditions, research settings, and whether they are over- or under-studied may help future prioritization of research initiatives and resources.

Developing a Water-stress Index for Potted Poinsettia Production
Authors: Nackley Lloyd L. , Fernandes de Sousa Elias , Pitton Bruno J.L. , Sisneroz Jared , Oki Lorence R.
Published: July 2020

Potted poinsettia (Euphorbia pulcherrima) is an important commercial commodity for the U.S. floriculture industry. The production of poinsettia demands intensively managed light control, heat, fertilizer, and water; inhibiting elongation with plant growth regulators, and protecting plants from diseases and pests with pesticide applications. Excessive irrigation creates pollution, promotes disease, and is expensive. Sensor-based control systems can optimize irrigation schedules. Irrigation management is crucial in nursery production of poinsettias because water is a limited resource and agricultural runoff is monitored in many states across the United States. By pairing environmental sensors with sensors that continuously monitor plant transpiration, we can determine how plant water use and water stress fluctuate with environmental and physiological demands. We hypothesized that continual measurements of sap flow could be correlated with environmental sensors to develop a new water stress index (WSI), which can deliver the benefits of detecting water stress that might affect the quality of potted poinsettias. To test this hypothesis, rooted cuttings of poinsettia (E. pulcherrima cv. Prestige Red) were individually potted into twelve 11-L black plastic nursery pots. Potted plants were grown in a naturally illuminated temperature-controlled glasshouse. The 12 plants were randomly assigned one of three watering treatments: weekly, biweekly, and triweekly irrigation. From the data collected, we were able to create a WSI that correlated available soil moisture with the difference between the expected transpiration with actual transpiration rates. Our results suggest that the plants in the weekly treatment group did not experience water stress until 0.3 m3·m–3 volume water content indicated by <0.2 WSI. These results support previous research that found 0.1 to 0.3 m3·m–3 can be stressful soil moisture conditions for greenhouse-grown crops. Results also show that for substrates with similar substrates that irrigation set points can be reduced to 0.2 m3·m–3 for improved irrigation efficiency.

Методи. Обстежено 56 осіб з постіммобілізаційною контрактурою ПЗС. Їх було поділено на дві групи: порівняння (займались згідно з принципами поліклінічної реабілітації) та контрольну (займались за розробленою програмою фізичної терапії – комбінація теплого вологого компресу в поєднанні з постізометричною релаксацією м’язів; масаж; функціональне тренування із застосуванням китичних тренажерів та еспандерів; лікування положенням за допомогою динамічних ортезів; кінезіологічне тейпування). Ефективність програми оцінювали порівнянням стану здорової та травмованої рук за результатами гоніометрії, мануального м’язового тестування, а також стандартних опитувальників АBILIHAND, DASH, HADS.

Результати. Після реабілітаційного втручання виявлено нормалізацію рухів ПЗС у пацієнтів основної групи за результатами гоніометрії та за результатами мануального м’язового тестування на відміну від пацієнтів групи порівняння (р<0,05). Результати тестування за опитувальником АBILIHAND показали покращення в групі порівняння на 46,49%, в основній – на 65,88%. За опитувальником DASH пацієнти групи порівняння досягли рівня функціонування руки «хороший», основної групи – «відмінний». Інтенсивність ступеня психо-емоційної напруги за обома шкалами HADS в групі порівняння зменшились до субклінічного рівня, в основній – досягла норми.

Висновки. Розроблена комплексна програма фізичної терапії виявила статистично значуще кращий вплив на показники психо-емоційного стану та функціональних можливостей передпліччя та зап’ястка в порівнянні з поліклінічною реабілітаційною програмою.

This study was aimed at identifying the thinking error of the students in solving mathematics problems and providing the scaffolding. The study was descriptive explorative. This study was conducted in Mojokerto.The subjects were 25 students, however, only 3 were described since the scaffolding used was of level 2. Data were collected initially by asking the subjects to solve mathematic test items. Error patterns were identified from the students’ works. The students who made errors were chosen as the research subjects. Findings show that there were differences in the students’ thinking patterns before and during the provision of scaffolding. These differences occur due to the different scaffolding treatments according to the thinking errors. For students who have difficulties in understanding problems, the scaffolding is in the form of leading questions. For those who have difficulties in connecting previous concepts, the scaffolding is in the form of drawing tables and recalling previous materials. For students who have difficulties in organizing a strategy, the scaffolding is in the form of recalling the strategy that has been plannedKARAKTERISASI SCAFFOLDING BERDASARKAN KESALAHAN BERPIKIR SISWA DALAM MENYELESAIKAN MASALAH MATEMATIKA Penelitian ini bertujuan untuk mengidentifikasi kesalahan berpikir siswa dalam menyelesaikan masalah matematika dan pemberian scaffolding.

Giving Your Electronic Health Record a Checkup After COVID-19: A Practical Framework for Reviewing Clinical Decision Support in Light of the Telemedicine Expansion (Preprint)
Authors: Feldman Jonah , Szerencsy Adam , Mann Devin , Austrian Jonathan , Kothari Ulka , Heo Hye , Barzideh Sam , Hickey Maureen , Snapp Catherine , Aminian Rod , Jones Lauren , Testa Paul
Published: July 2020

BACKGROUND

The transformation of health care during COVID-19, with the rapid expansion of telemedicine visits, presents new challenges to chronic care and preventive health providers. Clinical decision support (CDS) is critically important to chronic care providers, and CDS malfunction is common during times of change. It is essential to regularly reassess an organization's ambulatory CDS program to maintain care quality. This is especially true after an immense change, like the COVID-19 telemedicine expansion.

OBJECTIVE

Our objective is to reassess the ambulatory CDS program at a large academic medical center in light of telemedicine's expansion in response to the COVID-19 pandemic.

METHODS

Our clinical informatics team devised a practical framework for an intrapandemic ambulatory CDS assessment focused on the impact of the telemedicine expansion. This assessment began with a quantitative analysis comparing CDS alert performance in the context of in-person and telemedicine visits. Board-certified physician informaticists then completed a formal workflow review of alerts with inferior performance in telemedicine visits. Informaticists then reported on themes and optimization opportunities through the existing CDS governance structure.

RESULTS

Our assessment revealed that 10 of our top 40 alerts by volume were not firing as expected in telemedicine visits. In 3 of the top 5 alerts, providers were significantly less likely to take action in telemedicine when compared to office visits. Cumulatively, alerts in telemedicine encounters had an action taken rate of 5.3% (3257/64,938) compared to 8.3% (19,427/233,636) for office visits. Observations from a clinical informaticist workflow review included the following: (1) Telemedicine visits have different workflows than office visits. Some alerts developed for the office were not appearing at the optimal time in the telemedicine workflow. (2) Missing clinical data is a common reason for the decreased alert firing seen in telemedicine visits. (3) Remote patient monitoring and patient-reported clinical data entered through the portal could replace data collection usually completed in the office by a medical assistant or registered nurse.

CONCLUSIONS

In a large academic medical center at the pandemic epicenter, an intrapandemic ambulatory CDS assessment revealed clinically significant CDS malfunctions that highlight the importance of reassessing ambulatory CDS performance after the telemedicine expansion.
Bubble study as a medium of contrast for computerized tomography coronary angiography. (Preprint)
Authors: Shah Vijay , Huang Justyn
Published: July 2020

BACKGROUND

Computed tomographic coronary angiogram (CTCA) is a non-invasive test with a negative predictive value of nearly 100% for the detection of coronary artery study. While diagnostic yield of a dedicated CTCA with bubble contrast is not yet evaluated

OBJECTIVE

To assess the diagnostic performance of injected bubble contrast and ability to measure difference in hounsfield units and use it as a "negative contrast" in computed tomographic

METHODS

This is a single center, single patient study. Baseline acquisition of a non-contrast CT scan was acquired to get hounsfield unit count in the aorta and pulmonary artery- (Calcium scan protocol) 1.4 mGy (19.5 mGy/cm). Secondly, Echo contrasts (Definity) - 5mls was injected and an echocardiogram confirmed filling in the aortic region. Finally, bubble contrast (1ml air, 8mls water and 1mls blood was drawn up and agitated through a 3 way tap) - was injected, a timing run was initiated to calculate for the bubbles to opacity the pulmonary artery. The same scan protocol was used– 1.4 mGy (19.5 mGy/cm).

RESULTS

Hounsfield units’ difference in the aorta and pulmonary artery from baseline compared to echo contrast and bubble contrast were not significant.

CONCLUSIONS

We believe this is the first ever recorded case to use bubbles as CT contrast. While results were not significant, secondary to small volume of bubbles injected. Further research needs to be implemented to assess clinical difference with amount of bubbles and volume required.

Kami Bali-Lampung: Politik Identitas Etnik Bali Migran dalam Masyarakat Multikultural Way Kanan, Lampung
Authors: Arifin Zainal
Published: July 2020

Artikel ini menjelaskan bagaimana politik identitas etnik yang dipraktikkan komunitas Bali migran di wilayah Lampung yang multikultural, dimana berbagai etnik di Indonesia bisa ditemukan dan bermukim di wilayah ini. Komunitas Bali bermigrasi ke Lampung melalui proses transmigrasi pada tahun 1963 akibat meletusnya gunung Agung. Salah satu pemukiman komunitas Bali migran tersebut ada di desa Bali Sadhar di Kabupaten Way Kanan Provinsi Lampung. Dalam beberapa kasus, komunitas Bali dengan sentimen identitas budaya Hinduisme Bali yang kuat acapkali mengalami konflik sosial dengan etnis lain disekitarnya terutama di wilayah pemukiman baru. Tetapi komunitas Bali (Sadhar) di Way Kanan Lampung justru hidup dengan harmonis dengan komunitas lain di sekitarnya. Temuan penelitian menunjukkan bahwa keberhasilan penyesuaian budaya dalam praktik politik identitas di kalangan komunitas Bali (Sadhar) ini dilakukan dengan meredefinisi nilai-nilai budaya (Hindu) yang mereka miliki sesuai dengan kondisi lingkungannya.
Faktor yang Mempengaruhi Niat Mengadopsi Usahatani Sayuran Organik di Kecamatan Getasan Semarang

Published: July 2020

Organic farming has attracted increasing attention in recent decades. Many believe this is necessary to maintain agricultural production while addressing environmental damages caused by conventional farming methods. However, the adoption of organic vegetable farming in Indonesia is still fairly slow. The fact that only a small number of farmers adopt organic farming begs explanation. Studies have shown that intention determines human behaviors. The problem is that intention to choose organic farming does not always manifest in behavior. To address this problem it is helpful to consider three factors affect how intention manifest in behavior, namely attitudes, subjective norms, and behavioral control. Based on in the case study on the central vegetable farming area of Kopeng village where conventional farming is still dominant, this paper analyzes the intention organic farmers in the light of the theory of planned behavior. Applying the SEM-PLS model of analysis, it identifies the key-driver organic farmers. This study found that farmers’ positive attitude toward organic farming is not the main drive in their shift from non-organic to organic farming. Rather than subjective norms, behavior control has the greater influence on the farmers’ choice to adopt organic vegetable farming. Famers view organic agriculture positively; but  the main obstacle is the access to information about organics, certification capabilities and other aspects of behavioral control  which make adoption rate for organic vegetable farming is still low.
DEVELOPMENT AND VALIDATION OF NEW SPECTROPHOTOMETRIC METHODS FOR ESTIMATION OF ANTIPSYCHOTIC DRUG ASENAPINE MALEATE IN PURE AND DOSAGE FORMS
Authors: EL-SHEIKH RAGAA , ELLATEIF AHLAM E. ABD , AKMAL ESRAA , GOUDA AYMAN A.
Published: July 2020

Objective: Three sensitive, simple, precise, reproducible, and validated spectrophotometric methods have been developed for the determination of anti-psychotic drug (asenapine maleate) in pure and pharmaceutical dosage forms.

Methods: The methods are based on the formation of yellow-colored ion-pair complex between asenapine maleate and three acid dyes, namely, bromocresol purple (BCP), bromophenol blue (BPB) and bromothymol blue (BTB) with absorption maxima at 410, 414 and 416 nm, respectively. Several parameters such as pH, buffer type and volume, reagent volume, the sequence of addition and effect of extracting solvent were optimized.

Results: Under the optimum experimental conditions, beer’s law is obeyed over the concentration ranges of 1.0–20, 1.0–14, and 1.0-16 μg/ml for BCP, BPB and BTB, respectively, with good correlation coefficients (0.9994-0.9998). The apparent molar absorptivity and Sandell’s sensitivity values are reported for all methods. The limit of detection (LOD) and the limit of quantification (LOQ) values are found to be 0.27, 0.30, and 0.25 μg/ml and 0.90, 1.0, and 0.83 μg/ml for BCP, BPB and BTB, respectively. The stoichiometric ratio of the formed ion-pair complexes was found to be 1:1 (drug: reagent) for all methods, as deduced by Job's method of continuous variation.

Conclusion: The proposed methods were successfully applied for the determination of asenapine maleate in pharmaceutical formulations with good accuracy and precision. Statistical comparison of the results was performed using Student's t-test and variance ratio F-test at the 95% confidence level and there was no significant difference between the reported and proposed methods regarding accuracy and precision. Further, the validity of the proposed methods was confirmed by recovery studies via standard addition technique in accordance with ICH guidelines.
Perceptual learning, talker specificity, and sound change
Authors: Tamminga Meredith , Wilder Robert , Lai Wei , Wade Lacey
Published: July 2020

Perceptual learning is when listeners hear novel speech input and shift their subsequent perceptual behavior. In this paper we consider the relationship between sound change and perceptual learning. We spell out the connections we see between perceptual learning and different approaches to sound change and explain how a deeper empirical understanding of the properties of perceptual learning might benefit sound change models. We propose that questions about when listeners generalize their perceptual learning to new talkers might be of of particular interest to theories of sound change. We review the relevant literature, noting that studies of perceptual learning generalization across talkers of the same gender are lacking. Finally, we present new experimental data aimed at filling that gap by comparing cross-talker generalization of fricative boundary perceptual learning in same-gender and different-gender pairs. We find that listeners are much more likely to generalize what they have learned across same-gender pairs, even when the different-gender pairs have more similar fricatives. We discuss implications for sound change.
Preparados para un virus nocturno: coronavirus, decisiones de política pública y vulneración de derechos en cinco municipios de Sonora, México
Authors: Peña Víctor S.
Published: July 2020

El objetivo es analizar las decisiones municipales tomadas bajo el argumento de que se realizan por causa de una situación excepcional: la Fase 1 del contagio de COVID-19 en México. La aproximación metodológica fue inductiva y focalizada en los cinco primeros municipios que decretaron toque de queda en Sonora (Nacozari de García, Caborca, Naco, Santa Ana y Moctezuma). Se emplearon entrevistas semiestructuradas y solicitudes de información pública. El resultado describe la racionalidad al decidir en contextos excepcionales. Las limitaciones del estudio son el corto tiempo en que las entrevistas se realizaron y la carencia de información pública. La originalidad de la investigación es el contexto en que se realizó, así como la exploración de las decisiones públicas en situación excepcional. Los hallazgos se presentan en cuatro categorías: racionalidad política, ilegalidad y aceptación; empleo de recursos conocidos; desvinculación, argumento de urgencia y comunicación simbólica; y falta de evidencia y el uso del respaldo legítimo.
Generating Fault-Tolerant Cluster States from Crystal Structures
Authors: Newman Michael , de Castro Leonardo Andreta , Brown Kenneth R.
Published: July 2020

Measurement-based quantum computing (MBQC) is a promising alternative to traditional circuit-based quantum computing predicated on the construction and measurement of cluster states. Recent work has demonstrated that MBQC provides a more general framework for fault-tolerance that extends beyond foliated quantum error-correcting codes. We systematically expand on that paradigm, and use combinatorial tiling theory to study and construct new examples of fault-tolerant cluster states derived from crystal structures. Included among these is a robust self-dual cluster state requiring only degree-3connectivity. We benchmark several of these cluster states in the presence of circuit-level noise, and find a variety of promising candidates whose performance depends on the specifics of the noise model. By eschewing the distinction between data and ancilla, this malleable framework lays a foundation for the development of creative and competitive fault-tolerance schemes beyond conventional error-correcting codes.

Authors: Vicher Diana
Published: July 2020

Este trabajo versa sobre la trayectoria que la noción calidad, en su acepción actual, ha seguido dentro de la administración pública. Se revisa su origen y los cambios que ha presentado el concepto. Particularmente, se hace énfasis en los hechos y el contexto que facilitaron que la calidad se erigiera como un eje de transformación que auguraba un mejoramiento sustancial en la forma de prestar servicios, desde la realización de cambios en los procesos internos de la administración pública, siguiendo con la aplicación de los procedimientos que las organizaciones lucrati- vas utilizaron para eficientar el desempeño, y terminando con las cartas de calidad en el servicio. En este tenor también se resalta la tarea que han desempeñado las organizaciones internacionales que han fomentado los modelos y estándares de calidad, con énfasis particular en la Organización Internacional de Estandariza- ción (ISO), para conocer su naturaleza y sus fuentes de legitimidad y autoridad para certificar a la administración pública. Finalmente, se revisa la aplicación de la calidad y las normas de calidad en la administración pública mexicana.

El artículo plantea la conexión entre el impacto organizativo del gobierno electrónico y el concepto de transversalidad, enfatizando en su definición los componentes de integración, coordinación y comunicación interdepartamental, así como la idea de proponer unos objetivos compartidos que no son propios de ningún ámbito de la organización sino generales del conjunto. A continuación se discuten, en clave neoinstitucionalista, su concreción en el campo de la organización, los roles directivos y los estilos de relación. La cultura de la transversalidad se plantea como un referente para el impulso de estrategias de gobierno electrónico en las administraciones públicas.
¿Qué ha salido mal?: hallazgos sobre la implementación de políticas públicas para la transparencia a partir de un caso instrumental
Authors: Peña Víctor S.
Published: July 2020

¿Qué sucede una vez que una decisión pública se lleva a la práctica? La respuesta a esta interrogante se encuentra en el campo de la implementación de la política pública, área estudiada de manera discontinua a lo largo del tiempo. Posterior a un recuento teórico, el presente artículo explora, a partir de un caso instrumental ubicado en un gobierno subnacional mexicano, que ha implicado llevar a la realidad una decisión legislativa relacionada con la transparencia. Entre los hallazgos destacan las situaciones de carácter político, los acuerdos entre grupos y por la concentración del poder en pocos actores por ejemplo, como elementos coadyuvantes en la disparidad entre lo planeado y lo ejecutado.
Colaboración público-privada para la revitalización de espacios urbanos: la introducción de los Business Improvement Districts en el ordenamiento jurídico español
Authors: Villarejo Galende Helena
Published: July 2020

Los Business Improvement Districts (BIDs) son organizaciones de carácter privado, o consorciado con las autoridades locales, creadas para ofrecer una mayor oferta de servicios adicionales dirigidos a la promoción económica y regeneración del área. Desde que nacieran en Canadá, hace más de cuatro décadas, esta nueva forma de colaboración público-privada en el ámbito del gobierno local ha proliferado en distintas ciudades de diferentes países. Este artículo tiene como principal objetivo analizar las experiencias comparadas del modelo BID y examinar, desde un punto de vista jurídico, qué medidas y reformas legislativas serían necesarias para trasladar esta fórmula de colaboración público-privada al ordenamiento jurídico español, así como la problemática que las acompaña.
¿Gestión de la violencia en el fútbol?: perspectivas críticas sobre Inglaterra y Bélgica
Authors: Segura M. Trejo Fernando , Murzi Diego
Published: July 2020

El artículo surge de la necesidad de revisar y pensar esquemas de regulación y gestión de la violencia en el espéctaculo del fútbol frente a la postura instalada de reclamo de mano dura. A partir de los contextos mexicano y argentino es posbible observar como los medios de comunicación, así como otros actores ligados al negocio citan con reiteración al éxito de Inglaterra con respecto a los hooligans. Frente a esta postura que se ha ido traduciendo también en dispositivos de seguridad, se busca aquí comparar dos enfoques de gestión: las transformaciones mercantiles en el fútbol británico y la experiencia belga de sanciones combinadas con esquemas de prevención social. El objetivo es así contribuir a generar debates de política pública a fin de encontrar herramientas útiles y discernibles para otros contextos.

Los organizadores de la Copa del Mundo de 2014 prometieron que ella generaría beneficios para Brasil. Sin embargo, esta promesa generó incredulidad y protestas por parte de la sociedad brasileña. A partir de una comprensión del endurecimiento de estas diferentes posiciones como un conflicto de interés en torno a las prácticas y sistemas de control de la vida, este artículo analiza la guerra biopolítica desarrollada lo largo de la organización de la Copa del Mundo de Brasil. Basado en la teoría política de Hardt y Negri y el Análisis del Discurso de Foucault como un método, el trabajo analiza un conjunto de 776 documentos. Ellos revelan, por un lado, un intento del gobierno por controlar la opinión pública. Por otra parte, el artículo muestra el desarrollo de una resistencia de la sociedad a esa acción gubernamental. Esta dinámica revela cómo la Copa del Mundo de 2014 ha jugado un papel en la crisis democrática brasileña actual.Guerra biopolítica e crise de representação democrática na copa do mundo 2014

Effect of Ethanol Extract of Jamblang Aceh (Syzygium cumini) in Diabetic Mice (Mus musculus) and Its Potential As Anti-Diabetic Agent
Authors: Sari Ayu  Nirmala , Januardi Januardi , Diningrat Diky Setya
Published: July 2020

Abstract : This study was designed to evaluate the anti-diabetic activity of the ethanol extract of Syzygium cumini leaves in alloxan-induced diabetes mice. The anti-diabetic activity of EDS was investigated in mice (Mus musculus SW.) Alloxan-induced diabetes. The effect of ethanol extract of Syzygium cumini leaves on normal blood glucose levels and oral glucose tolerance tests were studied in normoglycemic mice while the anti-diabetic effect was evaluated in alloxan-induced hyperglycemic mice. Ethanol extract of Syzygium cumini leaves (200 and 400 mg/kg) is given orally for 21 days. Glibenclamide (5 mg/kg, oral for 21 days) is used as a reference standard. Giving ethanol extract of Syzygium leaves causes a significant decrease in blood glucose levels in normoglycemic and hyperglycemic mice and also increases glucose tolerance test. Ethanol extract of Syzygium leaves reduces glycosylated hemoglobin levels, lactate dehydrogenase, and creatinine kinase in alloxan-treated mice. Ethanol extract of Syzygium leaves also improves TBARS oxidative stress parameters, catalase and superoxide dismutase activity and glutathione levels. The ethanol extract of Syzygium cumini leaves shows anti-diabetic activity through increased insulin secretion and this effect can be attributed to the content of flavonoids and phenolic compounds present in the ethanol extract of Syzygium cumini leaves.Abstrak : Penelitian ini dirancang untuk mengevaluasi aktivitas anti-diabetes dari ekstrak etanol daun Syzygium cumini (L) Skeels (EDS) pada mencit diabetes yang diinduksi aloksan. Aktivitas anti-diabetes EDS diselidiki pada mencit (Mus musculus SW.) diabetes yang diinduksi aloksan. Pengaruh ekstrak etanol daun Syzygium cumini (EDS) pada kadar glukosa darah normal dan uji toleransi glukosa oral dipelajari pada mencit normoglikemik sedangkan efek antidiabetik dievaluasi pada mencit hiperglikemik yang diinduksi aloksan. EDS (200 dan 400 mg/kg) diberikan secara oral selama 21 hari. Glibenclamide (5mg/kg, oral selama 21 hari) digunakan sebagai standar referensi. Pemberian EDS menyebabkan penurunan signifikan dalam kadar glukosa darah pada mencit normoglikemik dan hiperglikemik dan juga meningkatkan uji toleransi glukosa. EDS mengurangi kadar hemoglobin glikosilasi, laktat dehidrogenase, dan kreatinin kinase pada mencit yang diberi aloksan. EDS juga memperbaiki parameter stres oksidatif TBARS, aktivitas katalase dan superoksida dismutase dan kadar glutathione. Ekstrak etanol daun Syzygium cumini (EDS) menunjukkan aktivitas antidiabetik melalui peningkatan sekresi insulin dan efek ini dapat dikaitkan dengan kandungan flavonoid dan senyawa fenolik yang ada dalam ekstrak daun.

Abstract : This study aims to determine the antidiabetic activity and toxicity of the acetone extract of Tristaniopsis merguensis Griff leaf. The antidiabetic test was the α-glucosidase inhibition method, while the toxicity test used the Brine Shrimp Lethality Test (BSLT) method. The acetone extract possessed antidiabetic activity with an IC50 value of 8.83 ± 0.31 (μg/mL). This value is not much different from the positive control of quercetin which has an IC50 value of 6.04 ± 0.14 (μg/mL). The characteristics of the FT-IR spectrum of acetone extract showed that Tristaniopsis merguensis leaf has the groups Ar-OH (phenolic), -OH (hydroxyl), C=O (ketone) and C=C (aromatic). Based on the toxicity test, the Tristaniopsis merguensis leaf acetone extract has an LC50 value of 959.25 ppm which means that the acetone extract is toxic. Therefore, the acetone extract of Tristaniopsis merguensis might be the potential agent of antidiabetic.Abstrak : Penelitian ini bertujuan untuk mengetahui aktivitas antidiabetes dan toksisitas dari ekstrak aseton daun Tristaniopsis merguensis Griff. Uji aktivitas antidiabetes ditentukan berdasarkan metode inhibisi enzim α-glucosidase, sedangkan toksisitas ditentukan berdasarkan metode Brine Shrimp Lethality Test (BSLT). Ekstrak aseton memiliki aktivitas antidiabetes dengan nilai IC50 8,83 ± 0,31 (μg/mL). Nilai ini tidak jauh berbeda dengan kontrol positif quersetin yang memiliki nilai IC50 6,04 ± 0,14 (μg/mL). Karakteristik spektrum FT-IR ekstrak aseton menunjukkan bahwa daun Tristaniopsis merguensis memiliki gugus fungsi Ar-OH (fenolik), -OH (hidroksil), C=O (keton) dan C=C (aromatik). Berdasarkan uji toksisitas, ekstrak aseton daun Tristaniopsis merguensis memiliki nilai LC50 sebesar 959,25 ppm yang berarti bahwa ekstrak aseton bersifat toksik. Oleh karena itu, ekstrak aseton dari Tristaniopsis merguensis berpotensi untuk dijadikan agen antidiabetes.
