Abstract

Background: Alkylation of DNA can occur at various site, however alkylation of the O6-position ofguanine has the strongest mutagenic potential. O6-Methylguanine is a toxic and mutagenic lesionwhich is formed in cellular DNA by alkylating agents. Alkyl group from carbanium ion can attack DNAforms alkylated DNA especially at O6 position of guanine. O6-methylguanine mispairs with thymineduring replication, and if the adduct is not removed, this results in conversion from a guanine-cytosinepair to an adenine-thymine pair. Deficient repair of O6-methylguanine has been suggested to be acontributory factor in the etiology of some diseases such as diabetes and cancer. This study aimed todetermine O6-methylguanine DNA concentration induced by N-[H3]methyl-N-nitrosourea ([H3]MNU)in rat liver cell culture with and without (-)-epigalocatechin gallate exposure.Methods: Primary rat liver cell culture was divided into 10 groups. Five groups for [H3]MNU 32 μMexposure, and 5 groups remain for 48 μM [H3]MNU exposure. Each group of [H3]MNU exposure gotEGCG 0 (as control), 8, 17, 33 and 67 ppm. The DNA was isolated, and O6-[H3]methylguanine DNAseparated by high performance liquid chromatography (HPLC). Concentration of O6-[H3]methylguanineDNA was measured by Liquid Scintillation Counter.Results: O6-Methylguanine DNA concentration decreased significantly in liver cell culture groups withEGCG. O6-[H3]Methylguanine DNA concentration in control groups for [H3]MNU 32 μM and 48 μMwere 29.89 ± 2.01 and 32.00 ± 1.67 fmol/μg DNA, respectively, while with EGCG 67 ppm were 1.87 ± 0.94and 2.38 ± 0.36 fmol/μg DNA.Conclusion: O6-methylguanine DNA concentration in liver rat culture induced by MNU decreasessignificantly after EGCG exposure. These findings support the conclusion that EGCG plays a key role insuppressing and inhibiting cancer development.Keywords:(-)-epigalocatechin gallate, N-[H3]methyl-N-nitrosourea, O6-methylguanine DNA, LiquidScintilation Counter

Abstract

Photoaging is skin aging, caused by chronic exposure of ultraviolet radiation. Photoaging decreases patients’ quality of life because the skin was the outer organ seen by others. Ultraviolet radiation causes oxidative stress, that activated inhibitory kappa B kinase (IKK), increased nuclear factor kappa B (NF-kB), matrix metalloproteinase (MMP), and degradation of collagen. Epigallocatechin-3-gallate (EGCG) was the main green tea polyphenol and the main source of biologic activity of green tea. This study was an in silico study, aimed to obtain the effectiveness of EGCG component through molecular docking on IKK receptor (PDB ID: 5EBZ). The bioinformatics tools based on reverse docking used in this study, were Protein Data Bank, ChemDraw, Chem3D, and Molegro Virtual Docker software. Docking and binding site analysis showed, that EGCG was able to interact with IKK receptor. Rerank score of interaction between EGCG and IKK receptor was higher than that of arbutin and 5TL_701[A]. It showed that EGCG has higher potential in photoaging prevention than arbutin, as one of the agents in photoaging prevention. Pharmacokinetics and toxicity (ADMET) prediction in this in silico study were conducted using pkCSM On Line tool. The pkCSM results showed EGCG was predicted having good pharmacokinetics profile without toxicity effect.

Abstract

Climate change that we are experiencing today is triggered by global warming which causes air temperature to rise, drought-land degradation, fluctuating rainfall, floods, landslides, pollution, and rising sea levels. In the agricultural sector, this results in decreased soil fertility, decreased agricultural yields, physiological effects on plants, weed disturbances and attacks by pests. Therefore, the estimation strategy and the provision of adaptive technology include applying plant-invitro culture technology that can adapt to climate change. The problem of this paper is the decrease in productivity and the stagnation of secondary metabolite biomass production in plants. This problem can be overcome by adapting in vitro culture techniques to produce secondary metabolites and plant development. In vitro culture has advantages including it does not depend on climate, altitude, weather and environmental temperature. The aim of this study was to adapt the in vitro plant culture techniques to obtain secondary metabolites and adaptive plant development. The method used is a review of the literature related to in vitro culture techniques that can produce secondary metabolite biomass and the development of various plant varieties. The conclusion of this research is that in vitro culture techniques can produce a variety of secondary metabolites and adaptive plants. The implication of this paper is to obtain a variety of secondary metabolite biomass and various plants that are resistant to climate change.

Abstract

Latar Belakang. Iodium merupakan mikronutrien penting terutama bagi perkembangan otak janin dan anak. Iodium berperan untuk proses pertumbuhan dan perkembangan sebagian besar organ terutama otak. Konsumsi iodium yang rendah dalam jangka panjang merupakan salah satu faktor yang dapat menyebabkan gangguan akibat kekurangan iodium (GAKI). Tingkat pengetahuan mengenai GAKI dan garam beriodium berpengaruh terhadap ketersediaan dan praktik penggunaan garam beriodium. Pemerintah telah mengupayakan penanggulangan GAKI melalui fortifikasi garam dengan iodium. Tujuan. Penelitian ini bertujuan untuk menganalisis pengetahuan ibu tentang iodium dengan ketersediaan garam beriodium di rumah tangga dan faktor yang memengaruhinya. Metode. Penelitian ini merupakan penelitian cross-sectional. Data diambil dari 198 rumah tangga menggunakan teknik proportional stratified random sampling. Penilaian pengetahuan ibu dilakukan dengan menggunakan kuesioner dalam bentuk pertanyaan tertutup. Sementara itu, penilaian ketersediaan garam diperoleh dengan pengujian kandungan iodium (KIO3). Uji statistik yang digunakan adalah chi-square test/fisher’s exact test dan Mann Whitney U/Kruskal Wallis untuk mengetahui hubungan antar variabel. Hasil. Sebagian besar responden tinggal di daerah dataran tinggi (74,2%), berpendidikan SD (47,5%) dan bekerja sebagai petani (41,4%). Karakteristik lokasi geografi tempat tinggal responden berhubungan dengan pengetahuan responden mengenai GAKI serta dampak dan faktor risiko GAKI (p=0,023 dan p<0,001), sedangkan pekerjaan responden berhubungan dengan pengetahuan mengenai dampak dan faktor risiko GAKI (p=0,020). Tidak ada hubungan antara pengetahuan dengan pemenuhan syarat mutu kandungan KIO3 pada garam yang digunakan di rumah tangga. Namun ada kecenderungan responden yang mempunyai garam dengan KIO3 sesuai, lebih banyak pada responden dengan pengetahuan yang baik. Kesimpulan. Responden dengan pengetahuan baik lebih banyak yang memiliki garam dengan kadar iodium sesuai standar. Perlu adanya program edukasi mengenai GAKI, penggunaan dan penyimpanan garam beriodium, serta faktor penyebab penurunan kualitas garam di rumah tangga.
