Abstract

Red palm oil (RPO) has various bioactive and nutritional components with high potential to be developed as a source of nutraceuticals in addition to its potential as a functional food. The fermentation technology is a processing process that affects metabolite activity, increasing the durability of a product. Staphylococcus epidermidis is one of the bacteria that is generally used in the sugar and oil fermentation process. RPO fermentation by Staphylococcus epidermidis is supposed to increase nutraceutical value by adding probiotic properties to RPO products. Moreover, the instability of bioactive compounds in RPO needs to be protected with coating technology microencapsulation. So, this study aims to formulate a microencapsulation procedure for fermented RPO using Staphylococcus epidermidis ATCC 12228 as a potential nutraceutical. RPO was fermented using S. epidermidis with three variations of MRS media and RPO comparison, then microencapsulated using emulsification and extrusion methods. The physicochemical properties and bioactivity of the product, microcapsule, were then analyzed. Our data shows that RPO fermentation was able to increase the chemical components. RPO fermentation produced more 1,2-Benzenedicarboxylic acid (2-Ethylhexyl) ester. Furthermore, microencapsulation of fermented RPO has better yield, efficiency, and solubility in water than non-fermented RPO microencapsulation. Moreover, our work also shows that the microencapsulation process increased RPO stability.

Abstract

Shallot seeds are a healthier option for cultivating shallots, as they reduce seed-borne disease infections, but they have a low germination rate. This study examined the impact of matriconditioning enriched with plant growth-promoting rhizobacteria (PGPRs) and rice washing water (WRW) on increasing germination, IAA content and growth of shallot seeds. The matriconditioning treatments included P0 (control), P1 (PGPR-absent), and PGPR presence in P2 (PGPR-Rhizomax), P3 (PGPR-BenprimA), and P4 (PGPR-FloraOne). The WRW treatments included L0 (0%), L1 (50%), and L2 (100%). The shallot seeds used are deteriorated, with moisture content and germination rates below the quality standards set by the Ministry of Agriculture of the Republic of Indonesia. The research revealed that treatment with P2 was the best result on seed germination and seedling root length. The treatment with P4 was the best result on seedling dry weight. The WRW treatment with L2 exhibited the best result in seed germination, seedling root length, and seedling dry weight. The combination of P2L2 demonstrated the best result on seed germination. The treatment with matricondiitoning increased shallot sprouts IAA content in 13-day-olds compared to controls. Also, the treatment with WRW linearly increased the IAA content in 13-day-old shallot sprouts.

Abstract

Paracetamol treatment is considered one of the treatments used to relieve pain and antipyretic. Therefore, excessive doses and long-term use lead to organ toxicity. Paracetamol treatment is considered one of the treatments used to relieve pain and antipyretic. Therefore, excessive doses and long-term use lead to organ toxicity. The aim of the study was to investigate the protective effect of Oleuropein extracted from olive leaves on the physiological and histological aspects induced by Paracetamol in a rat model. The methods used 25 albino Swiss rats randomly distributed into five groups with the same number. The unit of control is given normal saline. Paracetamol (750 mg/kg) was injected into the group once. In the treatment groups (50 mg/kg, 100 mg/kg, 150 mg/kg). The Administration of Paracetamol's result significantly increased blood urea, creatinine, sodium, and potassium levels, and their blood concentrations decreased with Oleuropein (P 0.05). In addition, Oleuropein extracted from olive leaves relieved some symptoms, including acute vascular congestion caused by a dose of Paracetamol. Compared with paracetamol treatment, there is an infiltration of inflammatory cells and severe nephrotoxicity in the tubules. According to this study, the Oleuropein extracted from olive leaves can be used to prevent kidney damage, and It is not recommended to give Paracetamol, which increases kidney disorders.

Abstract

The objective was to assess a range of stress indices to discern wheat genotypes resilient to drought stress, so forty-nine genotypes underwent scrutiny in both drought stress in rainfed conditions and non-stress settings (with supplementary irrigation), employing a 7 × 7 lattice layout with two replicates across years 2019 and 2020. The evaluation incorporated twenty stress indices anchored in yield under water stress (YS) and potential (YP) circumstances. Primary analysis indicated that eight indices (RDI, YSI, YI, K2STI, MRP, REI, RR and SSPI) did not give any new information, so they were eliminated in further analysis. Genotypes G33 (4234 kg ha-1) and G9 (2227 kg ha-1) were the best genotypes based on YP in 2019 and 2020, respectively. A positive association was observed between ATI and YP and between YS with DI and K1STI in the year 2019, while in the second year, such positive associations were not seen. We found some wheat genotypes G6, G9, G10 and G11 demonstrated high performance in both potential and rainfed conditions across two years, showing yield higher than 1,800 and 2,700 kg ha-1 for YS and YP, respectively, across both years. These genotypes were detected as the most tolerant genotypes by mean-based indices (TOL, HM, GMP, and MP) as well as SSI and ATI indices, so it can be concluded that these indices are more useful than other indices for identifying the most tolerant as well as the high yielding genotypes.

Abstract

The pelagic thresher shark (Alopias pelagicus) and bigeye thresher shark (Alopias superciliosus) are important shark species for Indonesia's consumption and finning industry. Both Alopias species are included in the CITES appendix II, thus requiring certain documents for trading. Regarding species identification for on-site application, the DNA isolation method is a crucial step. In this study, we developed a DNA isolation method suitable for on-site application based on isothermal amplification (LAMP) and species-specific COI gene markers. Three different extraction methods were applied, namely modified spin column kits and dipsticks. The quality of DNA was evaluated and tested for isothermal amplification using a reference sample, fresh fillet, and ethanol-preserved sample. The extracted sample concentration was in the range of 135.35-0.65 ng/μL. The LAMP test showed that three different DNA extraction methods successfully amplified the DNA fragments through the color changes at the end point of the LAMP reaction. The LAMP test was also sufficient to detect less than 10 ng of DNA from A. pelagicus and A. superciliosus within 30-50 min. The DNA from the modified spin column and dipstick extraction method combined with LAMP can potentially be used to detect Alopias pelagicus and Alopias superciliosus species on-site.

Abstract

The selection of tree species suitable for restoration in diverse site conditions is still a challenge. Therefore, this study aimed to analyze the phenotypic and genetic characteristics of Dryobalanops aromatica seedlings growing in mineral soil media and peat media. Phenotypic characteristics were evaluated by analyzing the growth performance, leaf morphological characteristics, leaf color, and chlorophyll content, while genetic characteristics were evaluated by using microsatellite markers. The study revealed that seedlings planted in peat media exhibited greater height and shoot length growth, although the difference was not statistically significant compared to those in mineral soil media. However, seedlings in mineral soil media displayed a significantly higher survival rate than those in peat media. Peat-grown seedlings had higher chlorophyll content in their leaves, while mineral soil-grown seedlings displayed a lighter green leaf color based on digital analysis. Genetic analysis indicated a high genetic diversity of overall D. aromatica seedlings (He = 0.635) and unclear genetic structure between the two media. Overall, these findings demonstrate the successful adaptation of D. aromatica seedlings to peat media, positioning them as a promising choice for peatland restoration.

Abstract

The global increase in multidrug-resistant (MDR) bacterial infection has rapidly gained concern globally. This study aimed to investigate antibacterial and antibiofilm potential of 25 soil actinomycete strains against MDR strains including Escherichia coli strain M4, Pseudomonas aeruginosa strain M19, Klebsiella pneumoniae strain M19, Bacillus subtilis strain M18, and Methicillin Resistant Staphylococcus aureus (MRSA). In this study, three actinomycete isolates encoded APM-7, APM-11, and APM-21 showed a strong and broad antibacterial spectrum. The minimum inhibitory concentration (MIC) of extracts derived from these isolates was ranged from 78 μg/ml to 10,000 μg/ml. In addition, The extracts also displayed significant biofilm inhibition values ranging from 6.06 to 72.4%. Based on the results, APM-21 extract had the best antibacterial and antibiofilm activities with the strongest values against MRSA. According to the nucleotide sequencing of the 16S rRNA gene, APM-7, APM-11, and APM-21 strains possessed similar identities with Streptomyces cyaneus, Streptomyces coerulescens, and Streptomyces panayensis, respectively. Based on Liquid Chromatography Tandem-Mass Spectrometry (LC-MS/MS) analysis, two antibacterial compounds, namely rancimanycin III, and enteromycin were detected in all those three extracts. Interestingly, APM-21 extract also contained two prominent antibacterial substances including paramagnetoquinone C, and caerulomycin I, suggesting their contribution to the most potential activities. Moreover, new insights were provided into a promising candidate for use in an active compound combating strategy to control MDR bacterial strain infection.

Abstract

The hyper-androgen and huritism in face and body in women is important diseases. It can be used as a possible marker in patients with ovary polycystic syndrome (PCOS). This study was carried out to evaluate DHEA and Testosterone levels associated with huritism and PCOS was studied in serum samples from pregnant, and non-pregnant patients and controls attending clinic Specialized. The study included 38 samples divided into three groups: 21 patients subjects, 6 pregnant women, 15 non-pregnant women with PCOS syndrome, and 17 normal subjects as control of the same age group. The target was selecting pregnant women due to changes in hormonal levels and physiological changes, as well as comparing them with non-pregnant women and control samples. The level of DHEAS was considerably higher in the median among pregnant women than in the control group and between non-pregnant and control groups without statistically significant differences between pregnant and non-pregnant values. Similarly, testosterone shows a statistically significant higher median among pregnant than control and also between non-pregnant and control groups without statistically significant difference between pregnant and non-pregnant values. In conclusion, this study detected a significant increase in testosterone and DHEA in non-pregnant women and then followed by pregnant women compared to the control, and age and the rise of these hormones are factors that cause the appearance of thick hair and thus cause polycystic ovary, which may lead to infertility.

Abstract

Black cumin (Nigella sativa) is a herbal plant that has been cultivated locally in Indonesia and is traditionally used for various diseases. Thymoquinone, one of the main components, is rich in biological activity. In several countries, topical application of its oil on human skin with vitiligo can stimulate skin repigmentation with minimal side effects. This study aims to determine the viability of B16F10 melanoma mouse cells against ethanol and n-hexane extracts of black cumin seeds through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The ethanol extract (EE) yield was 14.306%, and the n-hexane extract (NHE) was 7.442%. Phytochemical screening of EE detected flavonoids, alkaloids, saponins, and steroids, and High-performance liquid chromatography (HPLC) detected 0.040% thymoquinone. The MTT test showed cell viability was >100% from EE at all treatment concentrations, namely 0.75-100 ppm and only 0.75-6.25 ppm for NHE. In conclusion, this study indicates that 96% EE of Nigella sativa is less toxic than NHE on B16F10 mouse melanoma cells and has potential as an alternative treatment for vitiligo, which needs to be proven in further research.

Abstract

Mirah chickens are Indonesian indigenous chickens that originate from Simalungun Regency, North Sumatera Province of Indonesia. The study aimed to determine the genetic characterization of Mirah chicken based on the mitochondrial D-loop region (838 bp). Twenty Mirah cocks from Simalungun Regency of Indonesia were used in the present study. The results showed that fourteen haplotypes were found in the studies of birds based on sixteen mutation sites. Therefore, these haplotype and nucleotide diversities in the partial D-loop region of the Mirah chicken were classified as high. The Median-joining tree revealed that the Mirah chickens were classified in a similar cluster with the Red jungle fowl (Gallus gallus). Ten haplotypes of birds were close to G. g. bankiva, and four haplotypes of birds were close to G. g. gallus. In conclusion, Mirah chickens had the genetic introgression from two sub-species of Red junglefowl, i.e., G.g. gallus and G.g. bankiva. Hence, the pure breeding program for Mirah chickens is important to conserve their genetic resources from extinction.
