Abstract

Yogurt merupakan salah satu makanan fermentasi dari susu dengan penambahan Bakteri Asam Laktat (BAL). Tujuan dari penelitian ini untuk mengetahui karakter biokimia dan profil protein yogurt kambing PE difermentasi BAL. Susu kambing dan sapi di perah pada pagi hari dan dibagi menjadi 5 golongan: susu segar (sapi dan kambing), susu fermentasi kultur tunggal dengan starter bakteri L. acidophilus, kultur ganda dengan starter bakteri L. acidophilus+S. thermophilus, dan kultur campuran dengan starter komersial (yogurt mix). Protein susu dan yogurt diisolasi dan dimurnikan dengan 5x volume ekstrak buffer lisis (4mM PMSF, 1x PBS, 0,05 % Tween 20) dan diekstraksi dengan sonikasi amplitudo 20%. Separasi pita protein dengan SDS-PAGE discontinous separating gel 15% dan analisis hasil elektroforesis dihitung berat molekulnya berdasarkan protein standar menggunakan Rf. Analisis densitas profil protein menggunakan software Quantity One dan SPSS 15.0. Hasil menunjukkan bahwa pada susu sapi dan kambing segar, kultur tunggal dan ganda, serta yogurt mix ditemukan Κ-casein, β-casein, dan α-S1 casein pada berat molekul antara 30-38 kDa. Sedangkan pada susu kambing segar dan yogurt mix pada berat molekul 36 kDa yaitu α-S2 casein. Secara umum komposisi protein antara susu sapi dan susu kambing adalah sama, tetapi masing-masing memiliki pita protein yang berbeda, sehingga diduga memiliki fungsi yang berbeda pula. Kata kunci: BAL, kasein, SDS-PAGE, susu kambing Etawah

Abstract

The python of Indonesian Sundaland has been traded for its distinct skin colour and patterns. The need for rapid method in cross-species amplification for Indonesian Sundaland python is useful to contribute in management of sustainability harvesting system. In this research, we screened 10 microsatellite primers which are previously used for Australian, New Guinean, Chinese and Burmese pythons and 7 potentially amplifiable primers for African and Asian reptiles. Python breitensteini showed a greater number of alleles (2-8 alleles) than Python bivittatus (1-3 alleles) and Python brongersmai (1-2 alleles). The observed and expected heterozygosity for all species were ranged from 0 to 1.00 and 0 to 0.79, respectively. According to the high cross-species amplification rates, 15 out of 17 primers were useful in assessing the genetic diversity and conservation genetic of Indonesian Sundaland python. Among the 15 primers, MS3 generated the highest number of allele for P. breitensteini (8 alleles), P. bivittatus (3 alleles), and P. brongersmai (2 alleles). We proposed MS3 locus as a suitable marker for Indonesian Sundaland python.Keywords: microsatellite, Python, Sundaland.

Abstract

We aimed to analyze the effect of CSN1S2 protein in Etawah crossbred goat milk and yogurt on the histopathology of the jejunum and the amount of cell damage in Complete Freund's adjuvant (CFA)-induced rheumatoid arthritis (RA) rats. The rats were divided into six groups: the untreated control rats (C), control rats were given CSN1S2 protein from Etawah crossbred goat milk (CM) or yogurt (CY), RA rats, RA rats given CSN1S2 protein from Etawah crossbred goat milk (RAM) or yogurt (RAY). Hematoxylin-eosin staining was conducted for the histopathological analysis of jejunum. Statistical analysis was done using one-way ANOVA (a significance value of p ≤ 0.05) followed by the Tukey test. Our study observed that the control, CM, and CY group have a normal histological structure of jejunum. The damage to the jejunum structure was reported in the RA group. The milk CSN1S2 protein was able to improve the structure of jejunum villi and increase the normal cell number in the jejunum of the RA group, similar to control. The RAY group showed an impaired jejunum structure and a high number of necrotic cells as in the RA group.

Abstract

Rheumatoid arthritis (RA) is an autoimmune disease that can cause progressive damage to the joints of patients. The number of patients is expected to increase, along with the exact cause of this disease remains unknown. However, there are several risk factors associated with RA, including dysbiosis. The purpose of this study was to characterize the composition of intestinal microbiota in the RA and control groups through fecal analysis and reveal the association of microbiota composition with RA disease in Indonesia, especially Malang. Fecal samples were obtained from RA patients and controls. Fecal analysis was carried out through several stages, namely the calculation of total bacterial colonies, isolation and characterization of anaerobic bacteria, calculation of the Simpson diversity index, and DNA isolation. Analysis of bacterial composition profiles in fecal was carried out using 6 specific primer sets through PCR analysis. The results of the 16S rRNA PCR analysis showed different microbiota compositions between RA patients and controls. The number of Enterococcus bacterial group was lower in the control patients than the RA group, whereas the Lactobacillus bacteria decreased in RA patients. In addition, our study found that the existence of bacterial isolate 11 changed the composition of microbiota in RA patients, and the DNA band only appeared in Universal primers. The diversity of bacterial species can provide symbiotic and pathogenetic effects in RA patients.Keywords: Dysbiosis, intestinal microbiota, PCR, rheumatoid arthritis.

Abstract

Aging is caused by an imbalance between antioxidants and ROS. Nuclear Factor Erythroid 2-related factor 2 (Nrf2) is a transcription factor that regulates antioxidant genes. Under normal conditions, Nrf2 will bind keap1 and cause degradation of Nrf2. Nrf2 activation can be stimulated by secondary metabolites, such as glucosinolate (glucoraphanin and sulforaphane) and phenolic (kaempferol and quercetin) groups found in broccoli (Brassica oleracea). The purposes of this study were to analyze the interaction of the four compounds with Keap1 through molecular docking, to identify interactions that inhibit Keap1, and also to know the bioactivity scores, drug-likeness, and bioactivity prediction of each compound. The Nrf2-Keap1 protein (ID: 2FLU) structure was retrieved from the protein database, whereas the quercetin (CID: 5280343); kaempferol (CID: 5280863), sulforaphane (CID: 5350), and glucoraphanin (CID: 656556) were obtained from the PubChem Database. Molecular docking was done with HEX 8.0. The docking results were visualized with Discovery Studio 2020. Drug-likeness and bioactivity scores of the compounds were identified using mollinspiration. Prediction of bioactivity was carried out with PASS Online. The results showed that the binding energy of quercetin with Keap1 was -268.72 kcal.mol-1, and glucoraphanin with Keap1 was -318.01 kcal.mol-1. We found that quercetin from the phenolic group and glucoraphanin from the glucosinolate group had a strong interaction with Keap1, indicated by the number of interactions occurred and the smaller energy needed. Hence both compounds could inhibit the interaction of Keap1-Nrf2. Consequently, Nrf2 could transcribe antioxidant genes. The interaction between Keap1 and quercetin may play a role related to ROS reduction activities, such as enhancing HMOXI expression. This study indicates that quercetin has more potential in drug development as peroxidase inhibitors.Keyword: Aging, bioinformatic, glucoraphanin, keap1, quercetin
