Abstract

Various diseases including cancer and cardiovascular diseasesare induced by free radicals via lipid peroxidation, protein peroxidation, DNA damage, and cellular degeneration in thecells.Piper betle L.,commonly called betel,belongs to thePiperaceae family.It originated from South and South Eas tAsia,and has been used as a traditional medicine by people theredue to its medicinal properties.In the present study, free radicalscavenging activity of ethanolic leaves extract of Piper betle L.together with its different solvent fractions(hexane,ethylacetate,butanol,and water)were evaluated by DPPH freeradical scavenging assay.The ethanolic extract and the ethylacetate fraction had shown very significant DPPH (1,1)diphenyl)2)picryl)hydrazyl) radical scavenging activitycompared to the other fractions.In DPPH free radical scavengingassay,the IC50 value of the ethanolic extract and the ethyl acetate fraction were found to be 17.431g/mL and 11.53 1g/mL, respectively. The free radical scavenging activity was assumed due to the total phenolic content.The total phenoliccontent was found to be highest in the ethanol extract(277.68µgEGCG/mg)and the ethyl acetate fraction(559.38µgEGCG/mg).The results concluded that the ethanolic leaves extract of Piper  betle L. and its ethyl acetate fraction have a consider ably freeradical scavenging activity.

Abstract

Breast cancer (BC) is the number one cause of deaths from cancer in women. Metastasis in BC is caused by immunosurveillance deficiency, including impairment of Natural Killer (NK) cell maturation, low NK activity, and decreasing cytotoxicity. This study was performed to improve activating receptors and cytotoxicity of NK cells using interleukin 15 (IL15) against BC cells. Human recombinant IL15 was used to induce NK cells. To evaluate the potential of IL15 in inducing NK cells, we measured the activating and inhibiting receptors (NKG2D, NKG2A), apoptotic potency of NK cells on BC cells (MCF7) using transwell assay. The IL15 inducer on the NK cell were measured NKG2D, NKG2A gene expression with quantitative polymerase chain reaction (qPCR), (GzmB) secretion using ELISA, apoptotic gene expression of MCF7 using qPCR. IL15 increased NKG2D expression 4.01-9.13%, but IL15 could not affect toward NKG2A expression on NK cells. IL15-activated NK cells, inhibited BC cells proliferation, induced apoptotic BC cells 25.89-32.19%, induced apoptotic genes of BC cells bax, p53. IL15 increase NK activating receptor (NKG2D), inhibit BC cells proliferation, induce apoptotic percentage and induce apoptotic gene expression.

Abstract

Pelatihan pencegahan dan penanggulangan Demam Berdarah Dengue telah dilakukan oleh tim pengabdi Universitas Kristen Maranatha di Kelurahan Sukagalih Bandung pada tanggal 4 Desember 2018. Tujuan pengabdian kepada masyarakat berupa pelatihan tersebut adalah agar masyarakat dapat mempunyai perilaku yang baik untuk mencegah peningkatan jumlah nyamuk penyebab Demam Berdarah Dengue. Hal ini disebabkan Indonesia termasuk negara beriklim tropis yang hampir pada setiap tahun dan di beberapa kota ditemukan banyak penderita yang terinfeksi penyakit Demam Berdarah Dengue akibat cucukan nyamuk Aedes aegypti betina. Para peneliti merumuskan bahwa iklim dapat mempengaruhi perkembangan nyamuk Aedes aegypti, sementara peneliti lain menyimpulkan bahwa iklim tidak mempengaruhi hal tersebut. Terlepas dari polemik tersebut, pada kenyataannya yang terpenting untuk mengurangi bertambahnya jumlah nyamuk adalah perilaku masyarakat sehingga diperlukan pelatihan kepada masyarakat untuk pencegahan dan penganggulangan penyakit Demam Berdarah Dengue. Metode yang digunakan adalah ceramah, diskusi, dan peran aktif masyarakat. Hasil yang diperoleh sampai makalah ini dibuat adalah meningkatnya pengetahuan masyarakat terhadap pencegahan dan penanggulangan penyakit Demam Berdarah Dengue yang diperoleh dari kuesioner yang disebarkan. Simpulan yang diperoleh adalah pemahaman masyarakat tentang hal-hal mengenai penyakit Demam Berdarah Dengue telah meningkat dengan rata-rata pemahaman sebesar 85,6%.

Abstract

Many people around the world believed that herbal tea had a lot of antioxidants contained in it, thus it was widely drunk all over the world. However, the antioxidant capacities of herbal tea may be various because it is affected by the usage of different plants as its primary ingredient. As a result, this study examines the antioxidant activity of herbal tea made from dried Citrus sp. and Clitoria ternatea flower petals. The antioxidant potential was assessed by performing a DPPH and H2O2 scavenging activity assay on 2,2-diphenyl-1picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2) scavenging activity assay, total phenolic, and flavonoid content assay, ABTS reduction, and FRAP assay. This study showed that pure telang (Clitoria ternatea) herbal tea has antioxidant properties. Dried Telang (Clitoria ternatea) tea had the highest activity of antioxidants as we refer to the results of it had the highest activity value in DPPH, ABTS, and FRAP assay and also had the lowest IC-50 value. Followed by TEMON infusion which showed the second-highest antioxidant activity after pure telang infusion. The decrease in antioxidant activity in the mixture of telang and lemon was due to the mixture of lemons which tended to have the lowest antioxidant activity among the three types of infusions tested. The addition of dried lemon has the aim of enhancing the flavor of the tea infusion.

Abstract

Various diseases including cancer and cardiovascular diseases are induced by free radicals via lipid peroxidation, protein peroxidation, DNA damage, and cellular degeneration in the cells. Piper betle L., commonly called betel, belongs to the Piperaceae family. It originated from South and South East Asia, and has been used as a traditional medicine by people there due to its medicinal properties. In the present study, free radical scavenging activity of ethanolic leaves extract of Piper betle L. together with its different solvent fractions (hexane, ethyl acetate, butanol, and water) were evaluated by DPPH free radical scavenging assay. The ethanolic extract and the ethyl acetate fraction had shown very significant DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activity compared to the other fractions. In DPPH free radical scavenging assay, the IC50 value of the ethanolic extract and the ethyl acetate fraction were found to be 17.43µg/mL and 11.53 µg/mL, respectively. The free radical scavenging activity was assumed due to the total phenolic content. The total phenolic content was found to be highest in the ethanol extract (277.68 μg EGCG/mg) and the ethyl acetate fraction (559.38μg EGCG/mg). The results concluded that the ethanolic leaves extract of Piper betle L. and its ethyl acetate fraction have a considerably free radical scavenging activity.Keywords: Piper betle L., Piperaceae, free radical scavenging, DPPH
