Abstract

The forest conversion into oil palm plantations in Belitung impacts the plant source for pollen and nectar to support the honey bee Apis dorsata. This study aimed to identify the plants used by A. dorsata as pollen sources in honey and bee bread in honey bee nests and to analyze the vegetation composition and structure surrounding the sunggau (artificial nesting site) in Belitung Regency. Honey from A. dorsata was collected from bee nests in sunggau on Kampak Island and Tanjung Rusa. The pollen grains from 20 ml honey were acetolysed and counted until 1,200 grains for each honey sample. In Kampak Island, we found eight pollen types in honey dominated by Rhizophora mucronate mangrove pollen and eleven pollen types in bee bread dominated by Melaleuca cajuputi. The pollen type in honey in Tanjung Rusa was similar to those in Kampak Island, and nine pollen types were found in the bee bread dominated by Elaeis guineensis. The vegetation analysis revealed that mangrove and heath forests in Kampak Island were dominated by Lumnitzera littorea and Melaleuca cajuputi, respectively. The results of this study confirm the bees' notable use of the mangrove ecosystem, which adds conservation value, especially in supporting bee management efforts in Belitung.

Abstract

This study aimed to determine the spermicidal activity of papaya seed oil (Carica papaya L) from local Bali varieties against Wistar rat spermatozoa by evaluating sperm quality and the correlation between the percentage of motility and viability spermatozoa to identify its active compounds. Papaya seed oil was obtained by extracting papaya seeds using n-hexane solvent. The study was designed as follows; group of spermatozoa Wistar rat were treated with NaCl 0.9% (control, P0), with Sodium carboxy methyl cellulose (NaCMC) 0.5% (P1), with n-hexane extract 0.1%(b/v) (P2), with n-hexane extract 0.3%(b/v) (P3), and with n-hexane extract 0.5%(b/v) (P4). Column chromatography was used to separate the n-hexane extract into two fractions, A and B. The spermicide test for fractions A and B followed the same design as the test for n-hexane extract but until the P7 group. The result showed that fraction B exhibited higher spermicidal activity, with 23.3% motility and 33.8% of viability sperm at 100 ppm. The identification of fraction B by LCMS showed at least 12 mixture compounds were venoterpine, vitamin K5, 5-phenyl-2-pyridinamine, harmalan, styrylquinoline, 1,2,3,4-tetrahydro-1-benzoyl-2-methyl-4-phenylamino-quinoline, calcitroic acid, siderol, N-benzyl-linoleamide, (3β)-3-(diisopropylamino)androst-5-en-17-one, pipereicosalidine, and 25-azacholesterol. Spermicidal activity may be a synergistic effect of several compounds that have a cytotoxic activity such as styrylquinoline, 1,2,3,4-tetrahydro-1-benzoyl-2-methyl-4-phenylamino-quinoline, siderol, and pipereicosalidine.

Abstract

Lobster Panulirus polyphagus has a fairly high economic value and is found in the estuary waters of Tarakan City. This research aims to study the growth and mortality model of Lobster P. polyphagus originating in the estuary waters of Tarakan City. The research method was carried out using a quantitative descriptive method. Sampling was conducted 14 times from December 2021-May 2022 using gill nets. The results showed that the male sex ratio was more than the female. Allometric growth of males and females is negative allometric with a thin body shape. The structure of the size obtained was mostly in males ranging from 18.3-20.6 cm, and females around 20.5-22.2 cm. The maximum length growth of P. polyphagus based on von Bertalanffy's growth model was 31.519 cm in males and 31.374 cm in females. The total mortality (Z) of P. polyphagus for males and females was 1.104 and 1.119; catch mortality (F) of 0.106 and 0.253; natural mortality (M) of 0.998 and 0.866; exploitation rate (E) of 0.096 and 0.226, respectively. The high natural mortality causes the extinction of the Lobster species, so good management is needed so that it is sustainable.

Abstract

Hypothyroidism is a popular endocrine disorder caused by a thyroid hormone deficit. Changes in the state of the thyroid gland significantly affect many organs, including the heart. This study examined the cardioprotective effects of an artificially induced hypothyroidism in female rats using an ethanol extract from the root plant Saussurea lappa (Costus). For the current study, 25 adult female albino rats were employed. They were split into five equal groups, including control, hypothyroid group, post-treatment group with costus extract, co-administered hypothyroid group with costus extract, and post-treatment group with levothyroxine. Thyroid hormones (T3, T4, and TSH), lipid profile, and oxidative stress indicators (catalase, superoxide dismutase, reduced glutathione, and lipid peroxidation levels) were also measured in the serum. The heart muscle was the subject of a histological research. The findings suggested that Costus root ethanol extract improved hypothyroidism in female rats, as proven by the reversal of many biochemical abnormalities and improvements in the heart's histology. Our study indicates that the root of Costus exhibited cardioprotection efficiency against hypothyroidism-induced serious effects on the heart, The antioxidant and radical-scavenging properties of its components may be responsible for this promising effect.

Abstract

Cultivated potato varieties are tetraploid and vegetatively propagated. Therefore genetic improvement for new traits is less effective through hybridization. The mutation is considered an alternative method for crop improvement of those varieties. This study aimed to evaluate the effects of gamma-ray irradiation on increasing genetic diversity among the somaclones and the changes in population structure. Forty-four somaclones were used as observed materials. The population was grown in a screen house using a completely randomized design with genotype (somaclone) as a single factor. Thirteen qualitatively and quantitatively morphological characters were observed. Six SSR markers were used for analyzing the population structure. The selection process was based on a weighting method divided into quartiles. Selected numbers were taken from quartile 3. Morphological analysis of stems and leaves resulted in five different somaclones, with significant differences in anthocyanin appearance and intensity of the green color of the leaflets. Diversity criteria based on quantitative characteristics showed a high level of diversity with a high heritability for tuber weight, length, and diameter and a moderate heritability for tuber number. Analyzing the population structure has offered insight into how gamma irradiation affected the somaclones. As a result of the selection, 12 somaclones met the requirements to serve as seed sources for field testing. It is expected that the results of this study will provide information about the diversity caused by gamma-ray irradiation treatment on potato somaclones and a method for improving the efficiency of the initial selection of potato populations.

Abstract

RNA-ligand docking is a part of computational biology, which is currently lowly recognized compared to the protein-ligand docking procedure commonly applied for drug discovery. This in silico study aims to create a simplified protocol for RNA-ligand docking, which is applicable to RNA-targeting small molecular drug screening. Four alkaloids (berberine, colchicine, nicotine, and tomatine) were subjected to this study and contended against the SARS-CoV-2 genomic RNA -1 PRF component targeting control drug, merafloxacin, including two known intercalator berberine and colchicine, a small alkaloid nicotine and a large alkaloid tomatine. The alkaloids were screened for drug-likeness properties (Lipinski’s Rules of 5 or LRo5), bioavailability indexes, and synthetic accessibility values using SwissADME before docking. The docking used PyRx – Autodock Vina and re-scored for RNA-ligand scoring using AnnapuRNA. The docking results have the interactions mapped using fingeRNAt and visualized using Discovery Studio. Molecular dynamics using CHARMM36 and AMBER forcefields were simulated in NAMD. The molecular dynamics 1 ns simulation results showed that the ligand interaction over time did not cause much interference with the RNA, indicated by the low number of RMSD changes between RNA itself and the RNA-ligand complex. Additionally, CHARMM36 forcefield provided more stable fluctuation compared to AMBER. The results indicated that tomatine disobeyed LRo5 and had a low bioavailability index and bad synthetic accessibility value, while the rest alkaloids passed. In the end, berberine has an even higher docking score than the control drug. The study also shows that this protocol can be useful for future RNA-ligand computational studies.

Abstract

Extracellular vesicles including exosomes, are produced by cells for intracellular communication. Preconditioning of parental cells influences exosome properties. The purpose of this study was to examine the effects of L-ascorbic acid (LAA) and cobalt (II) chloride (CoCl2) on human Wharton’s jelly mesenchymal stem cell (hWJ-MSC)-derived exosomes and their ability to promote stem cell differentiation into chondrocytes. The cells were isolated from the umbilical cord and characterized according to the criteria for mesenchymal stem cell. The cells were cultured in a serum-free medium containing LAA and CoCl2. Cell-produced exosomes were isolated and characterized. hWJ-MSCs can grow in serum-free medium containing LAA and CoCl2. Exosomes derived from hWJ-MSCs had a round morphology, particle size within the exosome range, CD 63 expression, and the capacity to be internalized by cells. The production of exosomes by hWJ-MSCs was enhanced by LAA treatment. LAA and CoCl2 promoted stem cell differentiation into chondrocytes, as indicated by the production of collagen type II and glycosaminoglycans. LAA and CoCl2 affect the properties of MSC-derived exosomes. LAA induces cells to produce exosomes in greater quantities, which have the potential to promote chondrogenic differentiation of stem cells.

Abstract

Pandeglang is one of the banana producer regencies of Banten, Indonesia, that produce 924 tons per year. However, information regarding the diversity of banana germplasm in this region is unavailable. This study explored districts Cadasari, Banjar, Jiput, Labuan, and Menes. Morphological characters were noted and used to identify the cultivars, subspecies, or varieties. In total, 22 accessions were collected from 22 collection sites. Based on morphological characters, we described 14 banana accessions of 10 cultivars, three accessions of wild Musa acuminata and one of Musa balbisiana. Considering its genome composition, five genome types we described among these banana cultivars, i.e., AA (divided into AA and AA wild), BB, AAA, AAB, and ABB. In this study, we did a principal component analysis and saw that AA wild and AAB were clearly separated, but the other genome types were clustered partially or included in one cluster. Our study expands the information on banana diversity in Indonesia. Further study on the potential of this banana germplasm to be used as a genetic resource to find resistance to banana diseases is needed.

Abstract

Social networking sites (SNSs) have increased in number and popularity for more than a decade especially for adolescents. Previous studies conducted in western countries have stated that using SNSs could exert positive and negative effects on various aspects of psychosocial development, one of which is empathy. The relationship between SNSs use and empathy has remained unclear, especially in Indonesia. Therefore, the present study aims to determine the relationship between SNSs and empathy on adolescents in Indonesia. This study recruited 1,638 students from junior and senior high school with ages ranging from 12 to 19 years randomly across several provinces in Indonesia. Data collection was carried out by administering online questionnaires to participants consists of informed consent, demographic data, intensity of SNSs use during the past week with the Social Networking Time Use Scale (SONTUS) method, and questions about empathy with the Adolescent Measure of Empathy and Sympathy (AMES) method. Our result showed that higher frequency of using SNSs significantly positive correlated with cognitive empathy, affective empathy, and sympathy among adolescents in Indonesia, which is similar to previous studies, so this may be a general pattern in adolescence. The connections made by SNSs is believed to increase feelings of humanity (sympathy) and also empathy to other humans.

Abstract

The association of type-2 diabetes mellitus (T2DM) and cataract with mtDNA mutation has been reported before. Despite the high prevalence of DM and cataract in Indonesia, a study of the mtDNA variants in Indonesia in correlation with the two diseases is still limited. MT.3243A>G is one of the hotspots mutations for mitochondrial diseases, but the explanation for its occurrence in patients with pure cataract is still elusive. Therefore, the objective of this study was to analyze the mitochondrial genome variants from T2DM and cataract patients in Indonesia using the direct sequencing method. The homology analysis of the genome to the Cambridge reference sequence resulted in 86 variants, including 20 variants that cause amino acid substitutions. Based on the Mitomap data, 17 of the 20 variants were novel. Upon comparison with the 12 normal variant genomes, 11 of 17 variants were suggested to be associated with T2DM and cataract diseases since they code the protein in complex-I (ND4L, ND5, and ND6), complex-III (cytb), and complex-V (ATP6) of the respiratory complex. Interestingly, MT.3316G>A, for the first time, is shown in a pure cataract patient. In addition, the novel phenotype of MT.5460G>A and MT.10398A>G were revealed, which are T2DM and cataract in one patient. Based on our study, these diseases might be related to the disruption of the ATP metabolism due to the structure and function changes of proteins involved in the respiratory complex. This discovery is expected to offer an understanding of the origins of gene-level clinical differences, particularly in Indonesia.
