Published: January 2024

Background: Heart rate metrics including the average heart rate, maximum heart rate, and minimum heart rate reflect the physiological condition of the heart. Clinically, determining the impact of ventricular and atrial ectopic beats on those three metrics is important because they indicate how hard the heart is working. Objective: To investigate the changes in heart rates of ventricular and atrial ectopic patients. Patients and Methods: In this study, data from 90 persons (30 with ventricular ectopic beats, 30 with atrial ectopic beats, and 30 healthy people) were gathered and analyzed to see what changes in heart rate metrics may occur in patients with ectopic beats. Results: According to our results, the three heart rate metrics in almost all three groups are statistically insignificant (p-value > 0.05). The average heart rate was significantly higher (p<0.05) in ventricular ectopic patients than in atrial ectopic patients. The effect of age and gender on heart rate metrics were statistically assessed. Conclusion: Despite the fact that no significant differences were found in all groups, there were certain differences that require further examination. One of the long-term objectives is to expand this study to incorporate electrocardiography (ECG) analysis in order to complete the comparison between the three groups. Keywords: Ventricular ectopic beats, Atrial ectopic beats, Heart rate
Relative Effects of Cluster Geometry and Density-of-States on s-Aminotetrazine Cluster Dissociation Dynamics
Authors: Quevada Nikko P.
Published: January 2024

The rates of bond breaking of the van der Waals bond in the aminotetrazine (AT)-methane, aminomethyltetrazine (AMT)-argon, and dimethyltetrazine (DMT)-argon clusters are measured and compared using fluorescence emission spectroscopy. The results suggest that the rate of breaking of the van der Waals bond depends largely on the cluster density of states and is more or less independent of the cluster geometry. Thus, the rates of bond breaking are quite similar for all three van der Waals clusters even though the AT-methane cluster has a different effective geometry compared to those of the AMT-argon and DMT-argon clusters. The relative rates of AMT-argon and DMT-argon clusters, which have similar geometries, are consistent with the differences in their cluster density of states.

Authors: Cordero Christian John , Marquez Kevinilo
Published: January 2024

This study aims to determine the effect of adding milled wood lignin (MWL) to the sun protection factor (SPF) of commercially available lotion and sunscreen. The MWL was isolated from Coffea Arabica L. husks using the BjÃ¶rkman method. FT-IR spectroscopic analysis showed two characteristic peaks located at around 1200 cm-1 and 1300 cm-1, which indicates the presence of guaiacyl and syringyl groups. UV-Vis spectroscopic analysis showed two peaks located at around 278 nm and 325 nm, which indicates the presence of guaiacyl and some conjugated phenolic groups, respectively. The isolated MWL was then added to commercially available sunscreen and lotion at various concentrations. The sun protection factor (SPF) was then determined using the Mansur method and UV-Vis Spectroscopy. Results have shown that from 0% to 40 % by mass of MWL added, there was an observable average increase from 0.90 to 13.86 SPF for lotion, while there was an increase from 26.47 to 34.00 SPF for sunscreen. Results suggest that for lotion the SPF significantly increased if MWL was added from 0% up to 40% while for sunscreen the SPF significantly increased if MWL was added from 0% up to 20%.
Redesigning an organic laboratory course for remote learning: incorporating Lab@Home kits and other techniques for teaching organic chemistry online
Authors: Muñoz Moli Mae , Guidote Armando Jr. M. , Enriquez Erwin
Published: January 2024

Many cities in the world were placed under various lockdowns to combat the spread of the COVID-19 pandemic, which also forced many schools to shift into full online mode of teaching and learning. In the Philippines, partial onsite classes only resumed after nearly 2 years of strict online classes. Of critical concern then was the teaching of laboratory courses. This necessitated the re-design of the usual laboratory experiments to a Lab@Home course to provide a semesterâ€™s worth of an organic laboratory course to college students of the Ateneo de Manila University. Here, we present a Lab@Home curriculum that covers core organic chemistry concepts, such as purification and separation of organic compounds, reactivity and qualitative tests, stereochemistry, and molecular spectroscopy (IR and NMR). This Lab@Home course involved sending boxed kits containing laboratory materials and reagents that allowed students at home to perform small-scale experiments. Aside from reinforcing key concepts in the accompanying lecture class, it also provided them with experiential learning of practical laboratory techniques such as setting up an experiment and real data collection. Safety first is maintained, and aside from providing the usual protective gear, safety is further assured with two important features: (1) the hazards classification of the reagents in the kit would not exceed the everyday life hazards of common household chemicals (e.g., kitchen cleaning reagents) and provided in very small amounts, and (2) running of experiments were done with online synchronous supervision majority of the time. The success of the course is the achievement of the CLOs, from the assessments as well as from feedback taken from surveys and interviews with students and instructors at the end of the semester. Overall student performance showed an average final grade of 85%, and student response to the curriculum was generally positive. Further improvements should be implemented to make experiments more enriching and ensure Lab@Home can become an effective tool for teaching remote laboratory classes.

Published: January 2024

Objective: To analyze the clinical effects of the combined application of self-made Lixin Granule and natriuretic peptide in treating refractory heart failure. Methods: From January 2022 to June 2023, 40 patients with refractory heart failure were randomly divided into groups using the envelope method. A reference group (n = 20) received conventional Western medicine treatment, while an observation group (n = 20) received self-made Lixin Granules and natriuretic peptide. Clinical efficacy, heart failure scores, traditional Chinese medicine (TCM syndrome scores, inspection indicators, and adverse reactions of the two groups were compared. Results: The effective treatment rate in the observation group was significantly higher than that in the reference group (P < 0.05). There were no significant differences in heart failure scores and traditional Chinese medicine (TCM) syndrome scores between the two groups before treatment (P > 0.05). However, both scores in the observation group were lower than those in the reference group after treatment (P < 0.05). Before treatment, there were no significant differences in the inspection indicators between the two groups (P > 0.05). After treatment, the left ventricular ejection fraction (LVEF) of the observation group was higher than that of the reference group, while the N-terminal pro b-type natriuretic peptide (NT-proBNP) level and fractional shortening (FS) of the observation group were lower than those of the reference group (P < 0.05). There were no apparent adverse reactions in either group during treatment. Conclusion: The combined application of self-made Lixin Granules and natriuretic peptide in treating refractory heart failure improved clinical efficacy, alleviation of clinical symptoms, and enhanced cardiac function. This approach is deemed safe and holds high application value.

The subjects of the study are the national currencies of the EAEU and CIS countries and the main areas of their application in modern conditions. The purpose of the work is to analyze the current state of the use of national currencies, including mutual trade, distribution and transfer of customs duties, organization of currency and commodity markets. The acceleration of the de-dollarization of the economies of individual countries and regions of the world has been established, depending on a credible plan to reduce inflation and specific microeconomic measures. It is revealed that the processes taking place in the CIS and the EAEU are in line with this global trend. Priorities and prospects for expanding the use of national currencies by the EAEU member states have been identified. It was noted that such an important instrument of economic cooperation of the EAEU member states as the mechanism for crediting and distributing the amounts of import customs duties is gradually being transferred to the use of national currencies, and the possibility of using the Russian ruble in it is being discussed. The important role of the Bank of Russia's Financial Message Transmission System, which guarantees the transfer of financial information between banking institutions and acts as a domestic analogue of SWIFT, is emphasized. The decree of the Government of the Russian Federation No. 20 dated 08/26/2022 on expanding the use of national currencies of the EAEU member states is considered in detail.

The main problem in this study is students' ability to think mathematically in solving mathematical problems in learning social arithmetic in their class through minimum guidance-based learning (PBL and DL). This research uses a mixed method to look at the description of students' mathematical thinking abilities and the tendency of these abilities based on students' self-efficacy levels. The results showed that the increase in students' mathematical thinking skills at each level of low self-efficacy based on n-gain calculations. In addition, there is no significant difference in the scores for improving students' mathematical thinking skills based on the learning model and the level of self-efficacy. There is no significant interaction between the Learning Model and the Level of Self-efficacy in determining the increase in the average score of students' mathematical thinking abilities. Other findings show that students with low self-efficacy tend to have limitations in the ability to think mathematically in the process of conjecture and convincing. On the other hand, students with moderate and high self-efficacy have more complete mathematical thinking abilities, including specialization, generalization, conjecture, and convincing. However, in the process of conjecture and convincing, two sub-processes are found, namely knowledge modification using factual knowledge, contextual tools, or substantive thinking, as well as the process of selecting relevant information in solving problems. Therefore, the two groups are divided into four groups based on the way students use conjecture and convincing mathematical thinking abilities, namely: (1) students use specialization mathematical thinking skills based on the knowledge learned from the teacher, (2) students use specialization mathematical thinking abilities based on knowledge acquired in everyday life, (3) students use convincing mathematical thinking abilities by examining the formula used or based on knowledge learned from the teacher, and (4) students use convincing mathematical thinking abilities based on the knowledge obtained in everyday life (factual knowledge).

Changes in Cuban socialist development strategy and sustainable development: Connection and limitations between PNDES 2030 and SDGs
Authors:   The Korean Association Of Area Studies, Kim You Kyoung
Published: January 2024

This article examines how PNDES 2030, based on the Cuban socialist development model, corresponds to the SDGs, and through this, assesses whether Cuba's socialist development model can realize sustainable development. Furthermore, we reviewed the limitations of Cuban-style sustainable development and examined the conditions for the Cuban-style sustainable economic development model to be compatible with the SDGs, the dominant development paradigm in the international community. Since 1990, Cuba has made efforts to transform its development model and establish a sustainable development model in order to break away from external dependence in its economic structure and at the same time actively respond to changes in the global economy. The Cuban government established the 'Cuban National Strategic Plan 2030 (PNDES 2030)' for sustainable development goals centered on six strategic axes, with 17 Sustainable Development Goals (SDGs), the mainstream paradigm, in each strategic axis. Detailed items were placed. These strategic axes were planned to coexist with the 17 sub-goals of the SDGs without significantly departing from the post-revolutionary socialist development perspective. However, in reality, the U.S. economic sanctions that have continued since the revolution are acting as an obstacle to PNDES 2030, which can be considered a Cuban-style sustainable development model, achieving certain economic results. Additionally, overcoming the inefficiencies and low productivity that occur within the framework of a planned economy can also be said to be an important condition for realizing sustainable development in Cuba.

Gender empowerment is one of the components of gender development achievement measures that is an important agenda at the global level in realizing the Sustainable Development Goals. The Gender Empowerment Index (GEI) of Indonesia has been continuously improving since 2010, indicating an increasing involvement of women in various areas of life. However, behind this upward trend in GEI, there is still inequality at the provincial level. Therefore, there is a need to formulate development strategies, one of which is gender-based. One possible step is to categorize regions in Indonesia based on their gender empowerment characteristics, so that government interventions can be targeted effectively.  This research utilizes two clustering approaches, namely Hierarchical Methods and Partitioning Methods, with data consisting of three variables representing the components of GEI for 34 provinces in Indonesia in 2022. The selection of the best method and number of clusters is based on internal validity and stability validity, followed by the determination of the smallest within and between standard deviation ratios. From the cluster analysis results, the best method is found to be K-means with a total of 5 clusters.

Aktivitas dan latihan fisik yang teratur dapat membantu untuk tetap sehat Namun demikian di sisi lain, latihan fisik sendiri berperan sebagai pemicu stres oksidatif. Jika pertahanan antioksidan kurang maka kerusakan dapat terjadi pada berbagai jaringan. Produksi oksidan yang berkaitan dengan latihan fisik dapat terjadi melalui beberapa jalur, yaitu: Kebocoran elektron dari rantai transfer elektron mitokondria, xanthine oxidase  mengubah hypoxanthine menjadi asam urat, namun dengan menggunakan oksigen sebagai akseptor elektron untuk membentuk superoksida selama reperfusi, produksi radikal bebas oleh NADPH oxidase, pembentukan superoksida pada mitokondria otot akibat peningkatan temperatur dan autooksidasi oksihemoglobin menjadi methemoglobin, menyebabkan produksi superoksida

Anemia hemolitik autoimun (Autoimmune Hemolytic Anemia = AIHA / AHA) adalah sebuah kelainan pada eritrosit yang ditandai dengan kerusakan eritrosit oleh autoantibodi dalam tubuh seseorang. AIHA dapat terjadi pada semua kalangan usia, namun paling sering menyerang usia di atas 40 tahun. Angka kejadiannya sebesar 17:100.000 orang per tahun dengan angka kematian hingga 11%. Secara umum AIHA terjadi secara intravaskuler dan ekstravaskuler dengan aktivasi komplemen atau tanpa aktivasi komplemen. Pada pasien AIHA biasanya mengalami pucat, lemas, dispnea, hipotensi, takikardi, ikterus pada mukosa kulit, splenomegali, dan hepatomegali. Untuk menegakkan diagnosis AIHA selain dari anamnesis dan pemeriksaan fisik, juga didapatkan dari pemeriksaan laboratorium yaitu berupa pemeriksaan darah lengkap, indeks eritrosit, LDH, bilirubin indirek, retikulosis, serta morfologi darah tepi. Selain itu perlu dilakukan juga pemeriksaan untuk mendeteksi autoantibodi pada eritrosit. Pemeriksaan ini biasa dikenal sebagai Coombs test yaitu berupa direct Coombs test (Direct Antiglobulin Test/DAT) dan indirect Coombs test (Indirect Antiglobulin Test/IAT).
Neglected Open Fracture Distal Phalanx of The Right Hand in Hemophilic Patient

Fraktur phalanx tercatat sebagai fraktur terbanyak pada ekstremitas atas yang memiliki komplikasi pasca trauma yang lama serta dapat menyebabkan gangguan pada fungsi jari tangan. Pada populasi anak, cedera ujung jari terhitung pada dua pertiga dari semua cedera pada tangan, dengan mekanisme cedera yang paling umum adalah benturan. Salah satu kondisi yang dapat mempengaruhi manajemen dan luaran dari fraktur phalanx ialah kondisi gangguan pembekuan darah seperti hemofilia. Pada jurnal ini dilaporkan kasus neglected fracture digiti III manus sinistra pada pasien laki-laki berusia 5 tahun dengan hemofilia tipe A yang telah mendapatkan tindakan amputasi namun tetap mengalami perdarahan di stump pasca operasi. Fraktur adalah kondisi yang cukup menantang pada pasien dengan hemofilia terutama pada kasus fraktur dengan displacement yang berat atau fraktur terbuka. Pada kondisi tersebut terdapat kecenderungan yang tinggi untuk mengalami perdarahan dan komplikasi signifikan lainnya. Pasien dengan hemofilia lebih mudah untuk mengalami neglected fracture apabila kondisinya tidak ditangani dengan baik karena cenderung lebih mudah mengalami sindrom kompartemen bahkan hanya dengan trauma ortopedik minimal.
