Authors: Goyal Ahsas , Singh Geetanjali , Verma Aanchal
Published: June 2022

Brain disorders are currently one of the world's most serious and difficult health issues.
These brain disorders are accountable for a massive number of morbidities and mortalities around the
world. The current treatments of these disorders are frequently accompanied by severe side effects and
cause a detrimental effect on health. Recently, plant flavonoids have sparked a surge in public and scientific
attention because of their alleged health-promoting impact and almost no adverse repercussions.
Also, scientific research has shown that phytochemicals possess numerous neuroprotective
properties under in vivo and in vitro conditions. Chrysin is a therapeutic phytochemical that falls under
the class of flavonoids based on its structure. The biological activities and pharmacological effects of
chrysin include anticancer, antioxidant, and anti-inflammatory activities as well as amyloidogenic and
neurotrophic effects. These therapeutic abilities of chrysin are attributed to its structural diverseness
arising in ring-A and lack of oxygenation in B and C rings. Several studies have highlighted the rising
significance of chrysin in a variety of brain illnesses, like Alzheimer's disease, Parkinson's disease, depression,
anxiety, brain tumours, epilepsy, multiple sclerosis, traumatic brain injury, spinal cord injury,
and ischemic stroke. This study depicts the relationship of chrysin with different brain-related disorders
and discusses the mechanisms responsible for the potential role of chrysin as a pharmacological
agent for the treatment and management of different brain disorders based on the results of several
preclinical studies and taking into account the therapeutic effects of the compound.

Authors: Talib Wamidh H. , Mahmod Asma Ismail
Published: June 2022

Background:

The activity of phytochemicals has a huge impact on pharmaceutical research
and developing new drugs. Hence, numerous studies have been conducted to investigate the efficacy
of different natural products and their potential to be used in different types of therapy.

Objective:

This study was carried out to investigate the biological activity of M. autumnalis crude
extract and fractions, and the assessment included antimicrobial activity, radical scavenging potential,
and their effect on the immune system. The work also emphasizes determining the chemical constituents
and the main bioactive compounds in M. autumnalis leaves.

Methods:

Ethanol crude extract was prepared by maceration method, followed by solvents fractionation
using n-hexane, aqueous/methanol, and water. Phytochemical analysis of ethanol extract using
LC-MS and total phenolic and flavonoid content were conducted. The immunomodulatory activity
was also evaluated by measuring the effect of M. autumnalis on splenocyte proliferation in the presence
and absence of mitogens. Nitro blue tetrazolium assay and neutral red method have been used to
determine the effect of M. autumnalis on the phagocytic activity of macrophages and the function of
pinocytosis, respectively. Antibacterial assay was applied using the microtiter plate dilution method,
and DPPH assay was used to determine the antioxidant activity.

Results:

The phytochemical analysis has shown the presence of flavonoids, polyphenolic compounds,
and other organic acids like quinic and chlorogenic acids. M. autumnalis aqueous fraction exhibited
high antioxidant activity with an IC₅₀ value of 23.67±0.3 μg/ml. Ethanol extract and n-hexane fraction
inhibited the bacterial growth of P. auriginosa with an MIC value of 25 mg/ml, while n-hexane fraction
was more active against C. albicans with an MIC value of 12.5 mg/ml. On the other hand, the
immune assay revealed a slight modulation of the lymphocyte and macrophage activity compared to
the control results.

Conclusion:

The results suggested that M. autumnalis leaves are rich in polyphenolic compounds and
its crude extract and fractions exhibited antimicrobial and antioxidant potential. However, further research
is needed to understand the effect of M. autumnalis on the immune parameters.

Published: June 2022

Dalam beberapa tahun terakhir dunia telah mengalami pasang naik produksi bahan bakar nabati, dari angka tahunan sebesar 9,2 juta ton pada tahun 2000 menjadi 95,4 juta ton pada tahun 2018. Kebijakan nasional tidak dibuat untuk menstabilkan sektor gula dan kelapa sawit, tetapi untuk mengembangkan industri BBN (Bahan Bakar Nabati) nasional. Tujuan dari makalah ini adalah untuk menganalisis kebijakan pengembangan bahan bakar nabati antara Kolombia dan Indonesia terkait dengan sektor gula dan kelapa sawit. Metode yang digunakan analisis deskriptif dengan cara studi pustaka, pengumpulan data, dan menganalisis kebijakan pengembangan bahan bakar nabati di Indonesia dan Kolombia. Pemerintah Kolombia memberikan mekanisme insentif untuk mempromosikan bahan bakar BBN, termasuk mandat untuk pencampuran bahan bakar nabati. Kebijakan harga ditetapkan dengan mempertimbangkan biaya peluang penggunaan bahan baku alternatif. Sedangkan di Indonesia, mandatori kebijakan BBN dalam rangka mengurangi ketergantungan atas impor minyak solar guna menghemat devisa Negara. Di Kolombia, penerapan kebijakan bahan bakar nabati memungkinkan terciptanya pasar etanol dan biodiesel yang sebagian berasal dari substitusi produksi gula dengan produksi etanol, dan interaksi dinamis antara produksi minyak sawit dan biodiesel. Di Indonesia, belum optimalnya produksi biodiesel dibandingkan dengan kapasitas terpasangnya dikarenakan oleh faktor ekonomi politik dan harga. Rendahnya serapan biodiesel yang secara tidak langsung menjadi kendala keberlanjutan program bioenergi nasional.

Authors: Endiyono Endiyono , Adhi M. Hanif Prasetya , Setiyabudi Ragil
Published: June 2022

Background: Coronary Heart Disease is one of the diseases that causes the most deaths in Indonesia. One of the causes of death from coronary heart disease is cardiac arrest. One of the help that can be given is CPR (Cardiopulmonary Resuscitation). CPR can be performed by ordinary people or trained personnel. The phenomenon that often occurs is that when compression is performed, students are often not optimal in providing compression in terms of compression depth. The impact of poor quality CPR can cause death, economic, psychological, social, and length of treatment.

Objectives: This study aims to determine the relationship between Body Mass Index (BMI) and the Quality of Cardiac and Lung Resuscitation Compression in Nursing Students.

Method: This study uses a descriptive analytic research, with an observational method using a cross sectional design using a total sampling of 46 respondents.

Result: Based on the results of Fisher's Exact test, p-value < (0.001 < 0.05) was obtained so that there was a relationship between student BMI and quality into compression. The quality of nurses' chest compressions in performing chest compressions is lacking, even though some nurses have had cardiopulmonary resuscitation training. Someone who has a high and low BMI in the hospital, it was found that when doing chest compressions the patient gets tired quickly, a high BMI is difficult to do chest compressions when getting into bed.

Conclusion: Body Mass Index can improve the quality of student compression in cardiopulmonary resuscitation. BMI indirectly plays an important role in the performance of nurses in order to provide optimal cardiopulmonary resuscitation.

Telemedicine Preparedness Among Older Adults With Chronic Illness: Survey of Primary Care Patients
Authors: Ufholz Kelsey , Sheon Amy , Bhargava Daksh , Rao Goutham
Published: June 2022

Background

Older adults are a high priority for telemedicine given their elevated COVID-19 risk and need for frequent provider contact to manage chronic illnesses. It seems that many older adults now use smartphones but few studies have examined their overall readiness for telemedicine.

Objective

The aim of this study is to survey older primary care patients about their telemedicine preparedness, including internet usage, internet-capable devices, telemedicine experiences and concerns, and perceived barriers. Results were used to inform a telemedicine preparedness training program.

Methods

Community-dwelling older adult patients (aged 65-81 years; N=30) with a chronic health condition that could be managed remotely who were present at a family medicine clinic that primarily serves an urban African American population for a prescheduled in-person appointment were asked to complete a brief survey written for this study. Data were collected February-June 2021 at a large, urban, Midwestern hospital. To minimize patient burden, the survey was limited to 10 questions, focused on the most critical topics.

Results

Most participants (21/30, 70%) reported having a device that could be used for telemedicine and using the internet. However, about half had only a single connected device, and messaging and video calling were the most commonly used applications. Few used email and none used online shopping or banking. Only 7 patients had had telemedicine appointments. Telemedicine users were younger than nonusers and used more internet functions than nonusers. Only 2 people reported problems with their telemedicine visits (technology and privacy). Nearly all respondents recognized avoiding travel and COVID-19 exposure as telemedicine benefits. The most common concerns were loss of the doctor-patient connection and inability to be examined.

Conclusions

Most older adults reported having devices that could be used for telemedicine, but their internet use patterns did not confirm the adequacy of their devices or skills for telemedicine. Doctor-patient conversations could be helpful in addressing telemedicine concerns but device and skill gaps must be addressed as well.
Javanese Royal Kingdom Addressing System in Kethoprak
Authors: Hanum Icha Latifa
Published: June 2022

Javanese language in the context of the royal kingdom has a complex system. This hierarchy-based speech slowly disappears as this system is declined nowadays in order to national and international politics (Blust, 2013). However, the pure form of Javanese language system, especially in the term of kingship, remains and is reflected in folk art as the society's response to its existence. Kings, as Weber (1978:294) argues, have to rely on the basis of legitimacy believed by their subordinates or followers as a way that explains their kingships in order to legitimize their rule as kings or leaders over their realms. Thus, this paper tries to briefly reveal the language and power relations in Javanese kingship by examining the system of addressing terms in kethoprak. Through critical sociolinguistics study of kethoprak discourse, the complex Javanese language system that is influenced by the royal kingdom and its structure are revealed. Overall, the use of addressing terms in the royal kingdom context was found to be dynamic, break and complement the related previous studies.

Buncis Kenya adalah kultivar introduksi dari Kenya, Afrika, memiliki tipe tumbuh tegak (bush type), sedangkan buncis lokal diartikan sebagai buncis yang lazim ditanam di Indonesia, memiliki karakter tipe tumbuh merambat (climbing type). Persilangan antara buncis Kenya dan buncis lokal dapat memperluas latar belakang genetik buncis yang ditanam di Indonesia. Penelitian ini bertujuan untuk menghasilkan buncis dengan tipe tumbuh tegak dan mengevaluasi keragaman genetik generasi F2 hasil persilangan tanaman buncis lokal Temanggung dan buncis Kenya. Penelitian dilaksanakan di greenhouse, rumah kasa, dan Laboratorium Pemuliaan Tanaman Fakultas Pertanian Universitas Gadjah Mada pada bulan November 2018 hingga Juli 2019. Bahan yang digunakan dalam penelitian ini adalah satu jenis benih buncis lokal Temanggung dan satu jenis buncis Kenya hasil introduksi sebagai tetua, generasi F1 sebagai hasil persilangan kedua tetua, dan generasi F2. Generasi F1 memiliki sifat-sifat kombinasi kedua tetua. Karakter-karakter yang terekspresi pada generasi F1 dan F2 lebih banyak dipengaruhi oleh tetua lokal, sehingga karakter yang terdapat pada tetua Kenya, terutama pada karakter tinggi tanaman dan tipe pertumbuhan belum terlihat pada generasi F2. Nilai heritabilitas arti luas pada karakter kuantitatif tergolong sedang hingga tinggi, namun karakter-karakter tersebut belum dapat dijadikan sebagai acuan di dalam tahap seleksi. Pada karakter kualitatif tipe pertumbuhan, posisi polong, dan warna biji dapat diduga dikendalikan oleh beberapa gen pada dua lokus.

Senyawa metabolit sekunder merupakan produk yang terbentuk dari proses metabolisme secara insidental dan umumnya tidak terlalu berpengaruh penting terhadap kehidupan organisme. Mentimun mengandung senyawa metabolit sekunder diantaranya alkaloid, glikosida, steroid, saponin, tannin, flavonoid, terpenoid, resin, polifenol, fenol, glikosida sianogenik, dan antosianin. Kandungan senyawa metabolit sekunder pada mentimun dipengaruhi oleh faktor internal (genetik dan fisiologis) dan lingkungan (suhu, salinitas, kekeringan, radiasi sinar UV). Senyawa metabolit sekunder pada mentimun berperan penting bagi kehidupan tanaman atau untuk kesehatan manusia. Senyawa metabolit sekunder pada mentimun berperan sebagai antraktan serta pertahanan tanaman terhadap herbivora, hama, dan patogen. Senyawa metabolit sekunder pada mentimun dalam dunia medis dapat mencegah berbagai macam penyakit seperti peradangan, infeksi bakteri, kanker, demam, diabetes, maupun gangguan pencernaan. Kandungan senyawa metabolit sekunder dapat ditentukan melalui analisis kualitatif (uji warna) dan kuantitatif (kromatografi dan spektrometri). Secara kuantitatif, kandungan senyawa metabolit sekunder harus melalui proses pemisahan melalui kromatografi (paper chromatography, thin layer chromatography, gas liquid chromatography, high performance liquid chromatography) dan diidentifikasi menggunakan detektor (spektrofotometer UV-vis, spektrofotometer IR, NMR spectroscopy, dan mass spectroscopy). Rasa pahit pada mentimun dapat diatasi dengan menggunakan varietas yang menghasilkan buah tidak pahit, menjaga suhu dan kelembaban tanah dengan menentukan periode tanam yang tepat disesuaikan data suhu bulanan, pengairan teratur, serta penggunaan mulsa organik

Published: June 2022

This study aims to analyze the structural model of the increase productivity and sustainability of rice farming in West Tanjung Jabung District. The data used are primary data obtained directly from farmers. The sample size used was 90 farmers. Sampling using simple random sampling method. The data analysis used the SEM Partial Least Square structural model. The results of the analysis show that the description of internal factors, external factors of farmers and the adoption of farming technology are in the medium category. The productivity and farming sustainability factors are in a low category. The determinant factor that greatly influences the productivity and sustainability of rice farming is farm income. Farm productivity and sustainability are significantly influenced by farmers 'access to credit, farmers' access to technology, and access to input procurement. The main determinant of productivity is the use of production inputs. The sustainability of farming is mainly determined by economic aspects, especially income. Models for increasing productivity and agricultural sustainability must pay attention to efforts to improve farmers' access to credit, access to technology and access to input procurement. Efforts are needed to handle the input output price for rice so that it can increase farmers' income.

Five respondents from two regions of Visayas were chosen using convenience and purposive sampling techniques. The researchers of this study used Descriptive Qualitative research design following Colaizzi’s method in thematic analysis. An online interview questionnaire was distributed to the respondents through Google forms and thematic analysis was used to analyze the data. The results indicated that teacher classroom management strategies undeniably played a vital role to maximize students’ engagement in an inclusive virtual classroom. On this basis, it is recommended that teacher classroom management practices should also investigate the variables that limit students' willingness to participate, as well as the importance of the entire class population in students’ engagement. And since our study solely identifies best practices and strategies to maximize student engagement, further study is needed to emphasize assessing teachers’ ICT skills, the parental factors, and appropriate assessment methods to give a greater understanding of the nature of why student engagement is declining in this new mode of learning.
Fincas, poder y cultura en Simojovel, Chiapas
Authors:   UNACH, Toledo Tello Sonia
Published: June 2022

El propósito de esta obra es mostrar cómo en estas relaciones sociales entre los finqueros, y entre éstos y los trabajadores indígenas se configuró el grupo propietario de las fincas, que mantuvo el poder en la región durante aproximadamente cien años. Esto no implica hacer a un lado a la población indígena, de ella se hará necesariamente alusión, pues una de las propuestas fundamentales que aquí se sostiene es que no es posible entender a ninguno de los dos grupos sin considerar su relación con el otro; ambos se configuraron mutuamente. Es también propósito del trabajo mostrar que la cultura de finca que se creó y reprodujo en la región de Simojovel era compartida por cada uno de los sujetos y grupos sociales desde la posición que ocupaban en el sistema de finca. Es decir, que a pesar de las diferencias por la posición social, económica, lingüística y cultural había concepciones y prácticas asumidas y aceptadas por todos los participantes del sistema. De esta manera en esta obra se presenta aquí algunas de las prácticas y formas de representación que sobre las relaciones sociales y laborales construyeron los sujetos sociales para entender la configuración por cierto heterogénea y desigual del grupo finquero de Simojovel.
Could You Make That Less Sweet?
Authors: Lai Ashley
Published: June 2022

Growing up, I loved sugary snacks and drinks and would often tag along with my parents to the grocery store so that I could get something for myself. Unfortunately, due to a family history of diabetes and a rather high sugar diet, I eventually became pre-diabetic at the age of nine. Luckily enough, I had early intervention and my doctor recommended a strict diet along with exercise; I was soon able to lower my blood sugar within the normal range. However, that didn't mean I wasn't devastated by lack of sweets and would stare with envy at my friends as they often had desserts with their meals. As I grew older and studied biology in college, I gained a better understanding of how the human body realized how important diet was to preventing disease. I now am much more health-conscious, being careful about what I eat and making time out of my day to exercise for at least thirty minutes.
I created this art piece to capture the distinct ‘sugar rush’ that you get from consuming something sweet. I wanted to showcase how sweets made me feel and why it was so hard for me to accept that I couldn’t eat sweets as I wanted anymore. In turn, I hope this art piece encourages others to reflect on their own diets.

El periodismo se está replanteando debido a la transformación de los medios y al impacto de las nuevas tecnologías en cada una de las fases del proceso periodístico. Estos cambios también han impactado al periodismo deportivo. Por tales razones, se traza el objetivo general de analizar cuatro diarios deportivos digitales colombianos de mayor consulta en el país: FutbolRed, Marca, AS y El Periódico Deportivo. Para ello se realiza una investigación cualitativa y cuantitativa descriptiva, analítica, correlacional y prospectiva mediante entrevistas, grupos focales, observación y encuestas.

Los hallazgos identifican que la actualización de información de estos diarios deportivos digitales la realizan en promedio cada tres horas, la interactividad con el usuario es esporádica, la producción de contenidos es por agregación con tinte de espectacularidad y poca profundidad, la agenda noticiosa es repetida, no distinguen lo significativo con lo irrelevante, priman la noticia y opinión, la gestión informativa es similar a la competencia, la suscripción es abierta y la distribución es automatizada en plataformas, redes sociales y correos electrónicos.

Se concluye que estos diarios han modificado la participación con las audiencias, las rutinas periodísticas en las redacciones, el consumo de nuevos contenidos, la circulación y el rating. Por consiguiente, estos medios digitales están implementando una ecología informativa novedosa que está impactando los estilos y prácticas del periodismo deportivo.

La necrológica como género periodístico cobra especial relevancia dentro del actual panorama de las narrativas que coadyuvarían a tejer la inseparabilidad de la historia individual y social, en la fundación de los géneros de vida y en el tratamiento de la actualidad, afirmación que obliga a explorar el origen de las representaciones que convergen en los “géneros de vida”, e inferir esa relación de manera particular en la necrológica. Este artículo explora aspectos de ese orden individual y social que circunscribe la conciencia de la finitud, en la vida y obra del sociólogo Alfredo Molano (1944-2019), Comisionado de la Verdad para el esclarecimiento de los hechos de guerra en Colombia y la construcción de la verdad (Comisión de la Verdad, 2020), quien en vida contribuyó a la construcción de una cultura de paz.Los “géneros de vida” se han desarrollado en diversos ámbitos, y las historias de la muerte que aparecen en el género necrológico no son intemporales y tienen su lugar en la historia. Está entre los orígenes fúnebres como “cierta mirada sobre la vida”. Revela las formas poco conocidas de un acontecimiento y entendido, muchas veces, como un proceso cuyo transcurso y cambio transforma también a la obra y al individuo.Las diversas representaciones periodísticas analizadas desde las realizaciones del género (tipificación, retratos en serie/individualizados, personalización de la información, tratamiento de la realidad a través de sus actores, efecto descriptivo, la aspectualización, la evocación, la aparición en género informativo o de opinión, interpretación o narrativo y la sección), están enfocadas en la finitud (obituarios, necrológicas, homenajes, biografías) y han sido recolectadas con la técnica cualitativa de la saturación.
