Authors: Widyatami Afifatul Ilma , Suryawan Dwi Ari
Published: July 2021

AbstractIndonesia is the country with the highest cases of dengue fever in Southeast Asia, according to The World Health Organization (WHO) from 1968 to 2009. DKI Jakarta with high population density and flood intensity being cautioned for being aware of cases of dengue fever, because it may make growth in dengue mosquitoes spreading. Data show that almost every year DKI Jakarta is in the top 10 provinces with the highest cases of dengue fever. By using the clustering method, it is possible to make groups of data with similar characteristics into specific classes. Data used is secondary data from 2016 which is collected from the website https://data.jakarta.go.id/. The result from clustering can be used to decide which zone needs special treatment based on numbers of dengue fever cases, prone to flood, areas wide, total population, temporary landfills, and green space numbers variables. From the analysis, we can conclude that DKI Jakarta has 19 sub-districts with high risk, 10 sub-districts with medium risk, and 15 sub-districts with low risk.Keyword: dengue fever, cluster analysis, DKI Jakarta AbstrakIndonesia merupakan negara dengan kasus demam berdarah dengue tertinggi di Asia Tenggara sejak tahun 1968 hingga tahun 2009 berdasarkan data World Health Organization (WHO).

Authors: Sudhakar Dr.K. , Amalraj Leo , Tejaswini V. Lakshmi , Sree N. Mourya , Harshitha P. Divya , Julie M. Rubika
Published: July 2021

A polymer is a material which consists of very large molecules, or macromolecules, composed of many repeating subunits. They are classified as synthetic and natural polymers both play essential roles in everyday life due to their broad spectrum of properties. The foremost important class of polymers is superabsorbent polymer (SAP) materials. They are hydrophilic networks which absorb and retain large amounts of water. SAPs are originally divided into two main classes. They are Synthetic (Petrochemical based) and Natural (e.g.; Polysaccharide and Polypeptide based). Most of the present superabsorbent polymers are frequently produced from acrylic acid and acrylamide solution or inverse-suspension polymerization techniques. These are not biodegradable and are harmful to the environment that causes pollution. So, we sought to make biodegradable SAP that can act as a fertilizer to improve the soil quality and water conservation in agricultural land.

PENDIDIKAN ISLAM MENGHADAPI REVOLUSI INDUSTRI 4.0
Authors: Pera Afrizal Ambo
Published: July 2021

Pendidikan Islam masih sangat jauh tertinggal dengan Barat disebabkan beberapa hal, di antaranya adalah: pertama, orientasi pendidikannya masih harus diperjelas arahnya pada tujuan yang semestinya sesuai dengan orientasi Islam. Pendidikan Islam hanya concern pada transfer pengetahuan keagamaan saja. Kedua, praktek pendidikan Islam masih memelihara warisan lama, sehingga ilmu yang dipelajari adalah ilmu klasik dan ilmu modern tidak tersentuh. Ketiga, umat Islam masih sibuk terbuai dengan romantisme masa lalu. Kebesaran umat Islam masa lampau sampai dengan saat ini masih mempengaruhi mindset umat Islam. Mereka masih berbangga dengan kejayaan masa silam, tapi tidak sadar bahwa kebanggan tersebut justru yang menyebabkan ketertinggalan. Keempat, model pembelajaran pendidikan Islam masih menekankan pada pendekatan intelektual verbalistik dan menegasi interaksi edukatif dan komunikasi humanistik antara pendidik dan peserta didik. Transformasi digital manufaktur dan pemanfaatan teknologi platform ketiga menjadi identitas revolusi industri 4.0. Teknologi informasi menjadi basis dalam kehidupan manusia. Semuanya tanpa batas dengan penggunaan daya dan data komputasi tak terbatas, karena dipengaruhi oleh perkembangan internet dan teknologi digital masif sebagai tulang punggung gerakan manusia dan mesin serta konektivitasnya. Revolusi ini akhirnya mengubah perspektif seseorang dalam menjalani kehidupan modern dan canggih. Klaus Schwab sebagai pendiri sekaligus ketua forum ekonomi dunia mempertegas kondisi di atas, masuknya era revolusi industri 4.0 ditandai dengan kemunculan superkomputer, robotika, kendaraan tanpa pengemudi, editing genetik dan perkembangan neuroteknologi yang memungkinkan manusia untuk lebih mengoptimalkan fungsi otak, kecerdasan buatan (artificial intelligence), big data, nano teknologi, robotik, internet, mobil tanpa pengendara, drone, pencetakan 3-D, nanoteknologi, bioteknologi, ilmu material, penyimpanan energi serta komputasi kuantum, seluruhnya ditujukan bagi kesejahteraan umat manusia.

Perkembangan ilmu pengetahuan dan teknologi semakin mendorong upaya-upaya pembaharuan dalam pemanfaatan hasil-hasil teknologi dalam proses belajar, dan tidak tertutup kemungkinan bahwa media harus disesuaikan dengan perkembangan dan tuntutan zaman. Karena dukungan media yang tepat, tujuan pembelajaran dapat tercapai dengan baik pula. Oleh karena itu, sebuah media pembelajaran akan mempengaruhi sampai tidaknya suatu informasi secara lengkap dan tepat sasaran, serta mempengaruhi hasil akhir dari proses pembelajaran tersebut. Pada zaman Nabi SAW sudah dikenal kegiatan belajar mengajar, sehingga kalau dilihat kembali pada zaman Nabi SAW, sebenarnya media pembelajaran itu sendiri sudah ada dan sudah diaplikasikan oleh Rasulullah SAW. Beliau dalam mengajarkan ilmu pengetahuan kepada sahabat-sahabatnya tidak lepas dari adanya media sebagai sarana penyampaian materi ajaran agama Islam.

Identification of Adaptive Capacity’s Drivers in an Urban River Neighbourhood based on Community Experiences
Authors: Mohd Firdaus Rohana , Rasidi Mohd Hisyam , Said Ismail
Published: July 2021

Urban river neighbourhood communities have been swiftly adapting to rapid urbanisation despite the unsolved issues with their rivers. These issues indicate that there are gaps that need to be addressed, particularly the ones related to social aspects. In an attempt to fill in those gaps, this study aimed to identify the drivers of the adaptive capacity of an urban river neighbourhood community in Kg. Pertanian, Kulai, Johor. Data were elicited through focus group discussions with 27 residents followed by subsequent personal interviews. The obtained transcriptions were analysed by Nvivo12. From the results, it was found that there were three dominant drivers, namely ‘community identity’, ‘community response’, and ‘stakeholder agency’. ‘Community identity’ refers to the community’s contentment with life and its essential neighbourly relationships. ‘Community response’ reflects the community’s process of learning from experience and how its residents used the knowledge to benefit the community’s well-being. Finally, ‘stakeholder agency’ encompasses the community’s engagement and communication with stakeholders to avoid conflict during upcoming planning for its urban river and neighbourhood. These drivers were based on the community’ experiences or social memory. Interactions during floods and community events became the foundation for social memory. The interactions also bonded the people in the community, which was evident from the residents’ participation. All in all, the adaptive capacity and consequently the resilience of the urban river neighbourhood community can be attributed to three drivers: ‘community identity’, ‘community response’, and ‘stakeholder agency’.

Published: July 2021

In recent years, Digital Leadership (DL) has been recognised as an important practice for school principals. DL focuses on Information and Communication Technology (ICT) in support of school principals’ leadership practice. This qualitative study was undertaken with the aim of understanding DL among principals from four High Performing Schools (HPS) in Malaysia, particularly from the perspective of public relations. Semi-structured interviews were employed involving four exemplar school principals as the main respondents and 12 school staff as the secondary respondents of the study. The findings indicate that social media has become the contemporary public relations conduit among exemplar Malaysian school principals. The findings also suggest that third parties, such as students, parents, and alumni, enhance school principals’ public relations practices via their social media accounts. The aforesaid findings have meaningful implications for other school principals in similar school settings and contexts to better integrate social media in their public relations practice, especially by leveraging third-party social media accounts.
Relationship between Online Interethnic Interactions on Interethnic Bridging Social Capital: A Study of Academic Staff in Malaysian Private Universities
Authors: Luan Ng Miew , Wan Halim Wan Puspa Melati , M Hafifi Ayesha Aqilah
Published: July 2021

For decades, the uniqueness of Malaysia’s multiethnic, multilingual, and multicultural characteristics have been the focus of thinkers and policymakers in their effort towards nation-building. Such effort has been complemented by the contribution of researchers who provide relevant data and findings. Though the area of interethnic relations and interactions in Malaysia has been well researched, there is a gap in the literature regarding online interethnic relations and its role in bridging social capital. Hence, this study examined the relationship between online interethnic interactions and bridging social capital as well as the moderating effect of ethnicity among academics in Malaysian private universities. Quantitative data was collected through online self-administered questionnaires with 118 respondents and analyzed using SmartPLs software. The findings revealed that online interethnic interactions were vital in bridging social capital between academic members in private universities. The predictors of online ethic interaction (β = 0.718, t = 15.158, f2 = 1.062) were found to have a positive relationship with bridging social capital. The R of 0.515 suggesting there is 51.5% of the variation in bridging social capital was explained by online ethnic interaction. However, there is no evidence of ethnicity as a mediating role in bridging social capital. The authors argued that the role of private universities in Malaysia as a catalyst towards nation-building should be recognized and leveraged.
Hydrological Modelling Studies of Paravar River Basin, a Tributary of River Godavari using HEC-HMS Model
Authors: Matli Chandra Sekhar , Hunashal Vinay S.
Published: July 2021

The Hydrologic Engineering Center’s Hydrologic Modeling System (HEC-HMS) is designed to simulate the complete hydrologic processes of dendritic watershed systems. The software includes many traditional hydrologic analysis procedures such as event infiltration, unit hydrographs, and hydrologic routing. The model is applied to the Pravara River Basin, which is a tributary of the Godavari River in the Ahmednagar district of Maharashtra (India). For the simulation of runoff, the daily precipitation data and daily observed streamflow data from 1999 to 2012 was collected and ten years of data from 1999 to 2008 was used for the calibration of the model and 4 years of data from 2009 to 2012 was used for the validation of the model. The calibration of the HEC-HMS 4.0 model for the study area is carried out by comparing the simulated daily streamflow with the observed flow at the outlet of the basin. For this particular study, the deficit and constant loss model is used to compute the losses from the watershed. Under prediction of high flows is an inherent problem seen in hydrological modeling of the basin in the present study. This is due to the lack of extreme event modeling capability of the hydrological model. The daily flows except extreme flows are better simulated. The ability of HEC–HMS to simulate the magnitude of the peaks in extreme floods in the river basin underscores the significance of the model application as a flood prediction tool. The HEC–HMS successfully reproduced low flows and thus the model is a useful tool to estimate low flows in advance based on drought forecasts.
Structural Pruning Effects on Stem and Trunk Strain in Wind
Authors: Gilman Edward , Miesbauer Jason , Masters F.J.
Published: July 2021

Pruning removes mass and reduces bending in the wind on the pruned stem. However, little is known about the impacts of structural pruning, which leaves some parts of the tree not pruned. This study was designed to measure change in stem and trunk strain (ε) in turbulent wind from reducing the length of one side of a codominant stem pair. Trees were placed in front of a storm simulator with airfoils directing 22 m/s wind at four frequencies f(a) = 0.3, 0.5, 0.7, and 0.9 Hz. Trees were subjected to 30 cycles at each f(a) at each of four pruning doses—0%, 33%, 66%, and 100% foliage (and associated branch mass) removed from the smaller codominant stem. This resulted in 16 trials on each of five trees. The nonpruned stem of a codominant pair experienced no ε change in wind following reduction or removal of the competing codominant stem. Strain (ε) on the pruned codominant stem and on the trunk below the union where stems join decreased linearly with pruning dose and increased with f(a).
Impacts of Wire Basket Retention and Removal on Planting Time, Root-Ball Condition, and Early Growth of Acer platanoides and Gleditsia triacanthos var. inermis

Published: July 2021

The use of wire baskets to maintain root-ball integrity has greatly increased the efficiency of balled-and-burlapped harvesting practices. Despite the advantages offered by these products, there is notable disagreement among green industry groups and practitioners regarding the effects of wire basket retention or removal at the time of planting. For this experiment, 30 Norway maple (Acer platanoides) and 30 honeylocust (Gleditsia triacanthos var. inermis ‘Skycole’) shade trees were evenly planted at two sites in the midwestern U.S. after random assignment of a wire-basket removal treatment (i.e., no removal/intact, partial removal, and full removal). Planting time and initial root-ball condition were assessed at the time of installation. Short-term growth and plant stress were assessed each season as trees became established in the research plots. Results indicate that treatment impacted both planting time (P < 0.0001; both sites) and root-ball condition (P = 0.0360 or P = 0.0049; depending on site). In contrast, treatment had limited impact on tree caliper, twig elongation, or chlorophyll fluorescence in the first two to three years after planting.
Pruning Severity and Crown Position Influence Aspect Ratio Change
Authors: Gilman Edward
Published: July 2021

Growth on one branch is suppressed in proportion to pruning severity, resulting in a predictable reduction in branch:trunk diameter (aspect) ratio. However, little is known about response to pruning multiple branches. Several of the largest branches on live oak (15.3 cm trunk diameter) were pruned with four severities (0%, 25%, 50%, and 75%), then branch, nearby stem, and trunk diameter were measured for five subsequent years. Rate of trunk diameter increase five years after pruning was greatest for trees pruned with the 25% severity. Aspect ratio on all three pruned and measured branches decreased with time after pruning, pruning severity, and increasing height in the crown. Mean aspect ratio ceased declining between three and five years after pruning. The decrease in aspect ratio over time and with increasing severity on pruned branches was less pronounced in the lower crown than in the upper crown. Smaller change in aspect ratio on pruned branches in the lower crown suggests that when structurally pruning trees, branches in the lower crown may require a higher pruning severity to effect the same change in aspect ratio as upper branches.
Two Hundred Years of Forest Change: Effects of Urbanization on Tree Species Composition and Structure
Authors: Dolan Rebecca
Published: July 2021

Despite their importance, the dynamics of urban floras are not well understood, and quantitative historical data are rare. The current study used three data sets for trees in Indianapolis/Marion County, Indiana, U.S., to document change over 200 years to the original beechmaple forest and to examine future implications of contemporary tree planting efforts in light of these changes. Data on tree composition and size collected before significant settlement in the early 1800s are compared with recent surveys of trees in remnant natural areas and with trees found on city streets and rights-of-way. All the species recorded in historical surveys are still present in either remnant natural area forests or among city street trees, but frequencies and sizes have changed, and many additional species are now present. Comparison of the composition of the original forest with current remnants shows a 95% decline of American beech (Fagus grandifolia), the most common species in presettlement forests. Sugar maple (Acer saccharum) has more than doubled in number. Silver maple (Acer saccharinum) is the most important street tree, with eight species of non-native broadleaf trees among the most common on city streets, along with evergreen gymnosperms that are not documented in the presettlement flora. Data for contemporary tree planting efforts in the city show a focus on native species that targets replacement of species that have declined in frequency, especially oaks, in proportions that should be sustainable. Patterns reported here are likely representative of those in many forested areas undergoing land conversion and development, so the findings apply to many cities.
Container Wall Porosity and Root Pruning Influence on Swietenia mahogani Root Ball Architecture and Anchorage After Planting
Authors: Gilman Edward , Paz Maria , Harchick Chris
Published: July 2021

The emerald ash borer (EAB), first discovered in North America in Michigan in 2002, continues to expand its distributional range. Early detection of EAB remains a major caveat in efforts to implement proactive management strategies. Past reports have shown that ash trees infested with EAB have an increased risk of branch failure and other symptoms associated with tree decline. Therefore, early detection efforts could be improved if a suite of tree symptoms—prior to visible signs of EAB infestation—can be identified. Researchers initiated a four-year study in Ohio, U.S. (2009– 2012) to investigate and document symptoms associated with the EAB–ash tree complex in urban sites. The prior history of EAB at the study sites ranged from ash trees with no visible evidence of infestation to those that were infested for more than two years. In trees shown to be recently colonized by EAB, visible signs of infestation, such as adult emergence holes, presence of EAB galleries, bark loss, and canopy loss were not always apparent. However, in EAB-positive trees, there was a significant tendency for the presence of cracks in scaffold branches, branch fractures within the upper canopy, and branch fractures specifically located closer to the union with the stem as opposed to at the branch tip or at the branch’s center of gravity. This study highlights tree symptoms associated with the initial colonization of EAB when host trees are still apparently healthy, which could greatly facilitate future detection efforts for EAB.
The Use of Ground-Penetrating Radar to Locate Tree Roots
Authors: Moore G.M. , Ryder C.M.
Published: July 2021

Until recently the only way to investigate tree root architecture and distribution involved the physical removal of soil. However, in the past decade, ground-penetrating radar (GPR), which has been used in many other industries for about 30 years, has been used to study tree roots. GPR is relatively new to Australia and the aim of this research was to assess its spatial accuracy and ability to detect tree roots. Three experiments were conducted using a 900 MHz GPR device (Tree Radar®). The first experiment tested the ability of GPR to detect roots of sizes 10 mm, 20 mm, and 40 mm in diameter at depths of 200 mm, 400 mm, and 800 mm, while the second experiment tested its capacity to resolve two roots placed close together. Roots of 20–30 mm in diameter were placed in pairs at 20 mm, 40 mm, and 80 mm apart at depths of 200 mm, 400 mm, and 800 mm. The final experiment used GPR to analyze the in situ root system of a small Pistacia chinensis (Chinese pistachio) after which the root system was excavated using an AirSpade® and counts of root numbers were undertaken and compared with the predicted results. GPR detected and discriminated tree roots accurately at 200 mm depth, but as the depth increased to 400 mm and then to 800 mm, the levels of error increased, probably due to the choice of antenna available for the experiments, leading to the presence of phantom roots in some results and the misdetection of true roots in others. Confounding of the signal with unexpected interference or inadequate signal processing was most likely the cause. In the final experiment, GPR missed many small roots in the trenches close to the tree and appeared to detect multiple roots as one. In the outer trenches, GPR predicted 52 roots in total but excavation revealed only one in these disturbed urban soils.
The Influence of Biochar, Slow-Release Molasses, and an Organic N:P:K Fertilizer on Transplant Survival of Pyrus communis ‘Williams’ Bon Chrétien’
Authors: Schaffert Emma , Percival Glynn

High mortality rates result from transplanting bare-rooted plants into urban landscapes where unsuitable soil conditions, such as low fertility and poor structure, often exist. Coupled with little aftercare, these losses can cause high economic losses to the industry. Previous studies have shown lowered transplant stress and higher survival rates through the addition of soil amendments at the time of planting to improve soil conditions. The efficacy of three soil amendments applied singly and in combination—biochar, slow-release molasses, and an organic N:P:K fertilizer—were investigated for their potential to reduce transplant losses of Pyrus communis ‘Williams’ Bon Chrétien. Results of this investigation showed that use of these soil amendments in virtually all cases had significant positive effects on tree growth and vitality across two growing seasons. For example, all amendments reduced mortality of Pyrus communis ‘Williams’ Bon Chrétien’ by 20% compared to none in treated controls, while increases in fruit yield and crown canopy coverage per tree ranged from 19.3% to 46.7% and 14.4% to 31.1% over non-amended soils when averaged over two growing seasons. Amendments of biochar with an organic N:P:K fertilizer and an organic N:P:K fertilizer alone showed, on average, the highest improvements in vitality and growth. Results indicate use of biochar, slow-release molasses, and organic N:P:K fertilizer amendments offer potential for increasing bare-root transplant survival and establishment of Pyrus communis ‘Williams’ Bon Chrétien.
Impact of Landscape Tree Stabilization System and Nursery Production Method on Anchorage and Growth

The purpose of this study was to evaluate growth and anchorage one year after landscape planting of red maple (Acer rubrum L. ‘Florida Flame’) from both a field and container nursery that were stabilized with above- or belowground systems. Trunk diameter increased more for trees planted from containers with soilless substrate (17 mm) than trees with a soil root ball from a field nursery (14 mm); however, there was no impact of nursery production method on tree height. Trees secured with a guying system grew less in trunk diameter than trees secured with a belowground system, with a tall wood stake system, or the non-staked control. Guyed trees were taller than trees secured with a root-ball stabilization system. More bending stress was required to winch trees transplanted from the field nursery than trees from containers immediately after releasing stakes one year after planting. There was no difference among stabilization systems in bending stress to winch to any trunk tilt angle, indicating similar anchorage across systems. Moreover, trees stabilized for one year required the same bending stress to winch as controls, indicating that stabilizing trees for one year with any of the systems tested did not reduce anchorage compared to non-stabilized trees.

Summary Objective: A case report of a 23-year-old pregnant woman diagnosed with Guillain-Barré syndrome in the 31st week of pregnancy. Case report: We present a case study of a patient in the 31st week of pregnancy hospitalized at the University Hospital in Brno for expressed bulbar syndrome, neck muscle weakness, paresthesia of the arms and medical history of diarrhea in the previous week. During hospitalization, there was a rapid progression of symptoms and respiratory failure, requiring orotracheal intubation. The diagnosis of Guillain-Barré syndrome was determined and intravenous immunoglobulin therapy was initiated. The pregnancy was terminated in the 32nd week of gestation based on the maternal indication after a completed lung maturation of the fetus. Conclusion: Guillain-Barré syndrome is a neurological disease that can rarely occur during pregnancy and puerperium. The syndrome presents a serious pregnancy complication with an uncertain prognosis and risk for both mother and fetus. If the syndrome is diagnosed in time and treated correctly, the prognosis is favorable despite the complicated course.

Presentamos un estudio de la escritura poética de Claudio Bertoni a partir del examen de la significación de las cosas, que nos permite identificar una poética que actualiza, entre otros aspectos, la fragilidad de la existencia humana. Recurrimos al comentario de textos de El tamaño de la verdad, libro publicado en 2011, donde se advierte el despliegue de afectos e intensidades que orbitan la relación entre el sujeto y los objetos precarios.
De crímenes de familia a crímenes de Estado
Authors: Paz- Mackay Maria Soledad , Gonzalez Hurtado Argelia
Published: July 2021

El problema acuciante de violencia de género que vive Latinoamérica ha sido abordado recientemente por el cine de Argentina y México. En este artículo analizamos dos importantes representaciones, Las tres muertes de Maricela Escobedo de Carlos Pérez Osorio y Crímenes de familia de Sebastián Schindel. Basándose en historias reales, los directores recurren a diferentes estrategias para visibilizar y fomentar la discusión sobre la violencia contra mujeres y sus secuelas. En Crímenes de familia Schindel atrapa al espectador proponiendo un rompecabezas narrativo en el que poco a poco va introduciendo el tema por medio del suspenso. En Las tres muertes de Marisela Escobedo expone a través del documental el calvario de una madre en búsqueda de justicia para su hija, víctima de feminicidio. A través del documental emocional y de denuncia, Pérez Osorio vigoriza el debate en torno a la justicia y la violencia de género. En este trabajo analizamos las estrategias narrativas elegidas por los directores para visibilizar y agudizar el debate alrededor de temas complejos como la violación, homicidio agravado por el vinculo y el feminicidio. En segundo lugar, nos centraremos en la perspectiva de la madre que reformula en su devenir temas cruciales como la toma de conciencia, la falta de justicia, la sororidad y el activismo. Por último, analizamos la elección de ambas películas de ser co-producidos y distribuidos por Netflix. Argüimos que estos estos tres elementos se combinan para conformar lo que Rita Segato llama una “contra-pedagogía de la crueldad”.
Deseo y Archivo. Apología por una literatura menor de las ciencias sociales
Authors: Juárez-Salazar Edgar Miguel
Published: July 2021

El manuscrito aborda la relación entre el deseo del investigador y los alcances de éste en el momento de investigar en las ciencias sociales. En un principio, se desarrolla la implicación y los afectos del investigador como elementos centrales en la investigación y como posibilidad de habitar un archivo. Tomando como punto de partida la noción de archivo propuesta por Jacques Derrida, el escrito problematiza los pasos políticos y económicos que sigue una investigación hasta quedar indexada y validada por los mecanismos de vigilancia de los archivos. Se propone, en paralelo, hacer una lectura negativa del deseo del investigador y de su escritura que busca destrabar las lógicas mercantilistas del saber y su relación con el capitalismo contemporáneo.
Alpinetin: anti-human gastric cancer potential and urease inhibition activity in vitro
Authors: Zhang Hui , Jiang Qian , Gong Guojin , Li Mingzhen , Alotaibi Saad H.
Published: July 2021

Introduction

Alpinetin is the bioactive component of a traditional Chinese medicine. This compound, one of the main constituents of the seeds of Alpinia katsumadai Hayata, is a member of the flavonoids, with anti-inflammatory, antibacterial, and other significant therapeutic activities of important potency and low systemic toxicity.

Material and methods

In our study, the inhibitory effect of isoliquiritigenin on HMG-CoA reductase showed a lower value of IC50 = 21.86 ±1.44 µg/ml. A molecular docking study was performed as a complementary study to provide additional data about the biological activities of alpinetin in the presence of urease. The docking calculations revealed that alpinetin with a docking score of –5.097 (kcal/mol) has an acceptable binding affinity to the enzyme, and because of various hydrophobic contacts and hydrogen bonds created by this chemical compound, alpinetin could be considered as an adequate inhibitor of urease.

Results

In the cellular and molecular part of the study, the cells treated with alpinetin were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay for 48 h as regards the cytotoxicity and anti-human gastric carcinoma properties towards normal (human umbilical vein endothelial cells (HUVECs)) and gastric carcinoma cell lines, i.e. SNU-1, Hs 746T, and KATO III. The IC50 values of alpinetin were 426, 586, and 424 µg/ml against SNU-1, Hs 746T, and KATO III cell lines, respectively. The viability of the malignant gastric cell line decreased dose-dependently in the presence of alpinetin.

Conclusions

It seems that the anti-human gastric carcinoma effect of the investigated molecule is due to its antioxidant effects.

Limfedema pada kanker payudara adalah terganggunya sistem limfatik sehingga menimbulkan akumulasi cairan yang kaya dengan protein di ruang interstisial yang menyebebkan terjadi pembengkakan lengan, bahu, leher, atau daerah thorak. Tujuan penelitian ini untuk mengetahui  risiko terjadinya limfedema pada pasien kanker payudara yang mengalami  infeksi setelah menjalani operasi terkait usia. Metode penelitian ini merupakan analisis lanjut berdasarkan penelitian induk sebelumnya yang menggunakan desain case-control pendekatan multicenter dengan total 110 subjek. Wawancara dan pengukuran telah dilakukan menggunakan kuesioner. Hasil dari penelitian menunjukan bahwa pasien kanker payudara yang mengalami infeksi setelah operasi 3,5 kali lebih berisiko terjadi limfedema dibandingkan yang tidak mengalami infeksi setelah operasi. Pasien yang berusia ≥ 50 tahun yang mengalami limfedema 1,4 kali lebih berisiko terjadi limfedema dibanding < 50 tahun. Kesimpulan, pasien yang mengalami infeksi setelah operasi dengan usia ≥ 50 tahun terhadap kejadian limfedema ditemukan 75,0% dengan aOR 1, ini berarti cOR ≠ aOR, sehingga ada indikasi sebagai faktor pengganggu, namun secara statistik tidak ada perbedaan yang bermakna dengan p value > 0,05.
