Published: November 2022

Background: Numerous types of research on malaria were done over a long period of time but there are still some unknowns. However, it is globally known that malaria is caused by the Plasmodium parasite, mainly and most lethally by Plasmodium falciparum. The purpose of this research is to understand the structure and function of three uncharacterized P. falciparum proteins (PF3D7_1468000, PF3D7_1147400, PF3D7_1351100) using bioinformatic methods in hopes to learn more about malaria.  Methods: The three uncharacterized P. falciparum proteins were inserted into Phyre2 for knowing the protein homology, InterPro, and SUPERFAMILY hidden Markov models for understanding the domain annotation, scanprosite for knowing the post-translational modification, Ramachandran plot for protein validation, and Yasara for visualizing the protein. Results: According to the Phyre2 results, the third protein showed the highest confidence and coverage level of 100%, followed by the second protein, and the lowest was the first protein. Interpro and SUPERFAMILY results identified the first protein as WD40 repeat superfamily, the second protein as Cytochrome C subunit II-like, and the third protein as CXXC motif. Scanprosite revealed all sequences possessing protein domains in which the first protein has three protein domains, the second protein has one protein domain, and the third protein has two protein domains. According to the Ramachandran plot, the first and second protein generally has an Î±-helix structure while the third protein has an overall Î²-sheet structure, which differs to some extent from the protein structure visualization. The three protein visualizations exhibited secondary structures and more than 50 amino acid residues for each protein. Conclusion: This research concluded that the second and third uncharacterized proteins (PF3D7_1147400, PF3D7_1351100) could be promising antimalarial drug targets leading to the P. falciparum parasite death.

Methods A survey of 240 mothers with infants aged 4-5 living in Seoul and Gyeonggi Province was conducted to collect information on variables of interest. Parent-child interaction, infant's self-regulation, and infant's caring behavior were scored using valid and reliable scales. Descriptive statistics were analyzed, and t-test and ANOVA were performed to see the difference in the respondent's caring behavior according to sociology-demographic characteristics. Pearson's correlation analysis was performed to analyze the relationship between the variables. Lastly, a multiple regression analysis was conducted to investigate the influence of infants' self-regulation and parent-child interaction on infant's caring behavior. Results The average of infant caring behavior, self-regulation, and parent-child interaction was higher than average. Girls’ score of the considerate behavior, a sub-factor of caring behavior was significantly higher than that of boys. There were also significant differences in the total scores of caring behavior and the sub-factors of the caring behavior (consideration of others, respect for diversity) between high-income group and others. A positive correlation was found between children's caring behavior, children's self-regulation, and parent-child interaction. Multiple regression analysis showed that infant's self-regulation was positively and significantly associated with infant's caring behavior, controlling for other variables. Conclusions We found that children's self-regulation is an important factor influencing children's caring behavior. To improve children's self-regulation, it is necessary to adopt a social relationship-centered paradigm in infant education fields. A future study is needed to examine the reason for not showing a significant relationship with infant caring behavior and parent-child interaction under the COVID-19 pandemic.

Hal ini dapat menyebabkan dampak fisik dan psikis bagi korban terutama pada anak-anak dan remaja. Para korban membutuhkan perawatan psikologis untuk membantu menyembuhkan Post Traumatic Stress Disorder dan untuk kembali ke kehidupan mereka secara adil seperti sebelum momen traumatis itu terjadi. Metode penelitian ini menggunakan rancangan penelitian kualitatif dengan pendekatan studi kasus. Hasil wawancara dan observasi terhadap  3 penyintas pelecehan seksual Fisik didapatkan gambaran bahwa subjek masih merasakan  trauma seperti mudah teringat peristiwa pelecehan seksual yang dialami, memberikan tanda stress melalui kode fisik, dan masih merasakan cemas. Sehingga kejadian  traumatis  tersebut dapat  mengakibatkan  gangguan  secara  mental,  yaitu  PTSD

Kesehatan mental merupakan kondisi mental yang ditandai dengan tidak adanya gangguan atau kecacatan mental. Permasalahan kesehatan mental yang sering dialami individu diantaranya adalah mengalami kegelisahan, tidak merasa adanya ketentraman, hingga mengalami gangguan kejiwaan. Maka dari itu, individu perlu memiliki kemampuan menjaga dan memelihara kesehatan mental yang baik agar terhindar dari gangguan kejiwaan. Kesehatan mental dapat diperoleh individu dengan memenuhi kebutuhan lahiriah maupun kebutuhan batiniah. Salah satunya pemenuhan kebutuhan batiniah dapat diperoleh dari kegiatan suluk yang merupakan metode pembinaan spiritual dan bertujuan untuk membentuk individu yang bertaqwa. Penelitian ini menggunakan teknik kuantitatif dengan jumlah responden sebanyak 58 jamaah, metode yang digunakan adalah purposive sampling. Metode analisis data yang digunakan yaitu berdasarkan uji t (t-test) menggunakan paired samples T-test. Hasil uji t (t-test) pre test ke post test menunjukkan nilai t = -17.400 dengan taraf signifikansi 0,000 (p<0,05) hal ini menunjukkan bahwa ada perbedaan yang sangat signifikan antara hasil kesehatan mental sebelum dan sesudah melakukan suluk dari pre test ke post test dengan skor rerata pre test 51,41 menjadi skor rerata post test 81,17.Mental health is a mental condition characterized by the absence of mental disorders or disabilities.

One of the most often evoked episodes of 20th century Russian-Indian interrelations is a short correspondence between Mohandas Karamchand Gandhi (1869 –1948) and Leo Tolstoy (1828 –1910). The correspondence lasted from October of 1909 up to November of 1910, that is during the very last year of Tolstoy’s life. The “corpus” of this correspondence consists of seven letters: four from Gandhi to Tolstoy and three from Tolstoy to Gandhi. Those letters have been published more than once and translated into various languages. But the circumstances of this correspondence, the history of its study, and the contents of the letters themselves — all this has been researched rather little. This paper is a preliminary study of several friends and associates of Gandhi during his stay in South Africa (1893 –1914). Those people were connected, one way or another, with the correspondence between Gandhi and Tolstoy. Here are their names: 1. Joseph John Doke (1861 –1913), a Baptist priest; he wrote the first biography of Gandhi; 2. Henry Solomon Leon Polak (1882 –1959), a journalist; Gandhi called him “a blood brother;” 3. Pranjivandas Jagjivandas Mehta (1864 –1932), a commersant; he financed a number of Gandhi's “projects;” 4. Louis (or Lewis) Walter Ritch (1868 –1952), a businessman; he corresponded with Leo Tolstoy before Gandhi; 5. Hermann Haim Kallenbach (1871 –1945), an architect; he built a house for Gandhi in Johannesburg; 6. Sonja (Sophia) Schlesin (1888 –1956), Gandhi's secretary and, sometimes, deputy; in his letters Gandhi addressed her as “my dear daughter;” 7. Pauline Podlashuk (1881 –1971), an immigrant from Lithuania; in 1910, she translated for Gandhi from Russian into English the last letter of Tolstoy. The personalities and legacies of these people, including their more or less voluminous correspondences with Gandhi, have been studied rather little. In this paper, problematic issues are defined and perspectives of further research are suggested.

Cell transplants in therapeutic studies are not preserving their long
term functional inside the donor body. In mesenchymal stem cells
transplants, transplanted cells disperse through body and easily
degraded by immune cells after transplant process. Various strategies
such as usage of the immunosuppressive drug to eliminate allograft
rejection are designed to increase efficiency of the cell therapy. The
other hand strategy is the construction of biomimetic encapsulates via
using polymeric materials which preserve of stem cells from
environmental effect. In this study, we hypothesize that L929 cell lines
and mesenchymal stem cell (MSCs) might continue their viability and
functionality inside the alginate microbeads during the 12 days of in
vitro conditions. For that purpose, uniform, and injectable size
(<200 µm) of cell-loaded microbeads were constructed by
electrostatically assisted spraying techniques. Our results showed that
both L929 and MSCs cell lines continue their metabolic activity inside
the microbeads and cells during the incubation periods. Glucose
consumption and lactic acid production level of both groups of the cell
lines were consistently observed. Released cell number at day 12 was
increased compared to day 0. Protein expression of both groups of the
cells was increased day by day with doubling of the cell number. In this
work, we illustrate that mesenchymal stem cells and L929 cells might be
used in 3D cell culture models.
