Nigella sativa or black cumin is one of the medicinal plants that botanically belongs to the Ranunculaceae family and is literally described as the 'seed of blessings' due to its medicinal use in Islamic historical background. Black cumin has a wide spectrum of pharmacological actions, but its stability is still a limitation. To overcome this, solid lipid nanoparticles (SLNs) was introduced as an alternative carrier system of active compounds. In this study, solid lipid nanoparticles containing black cumin seed oil were successfully prepared by the emulsification-ultrasonication method. The effects of different emulsifiers were studied in terms of particle size. The particle size decreases with increasing lecithin/emulsifier concentration. The dynamic light scattering analysis of solid lipid nanoparticles confirmed the particle diameter of the formulated SLNs stabilized with poloxamer and tween 80 was approximately 220 nm to 1.2 µm. The results obtained from scanning electron microscopy (SEM) revealed the sphere-like shape of SLNs. From the SEM analysis, the diameter of the SLNs was in the range of 250 - 900 nm. Physiochemical characterization using DSC technique demonstrated a difference in crystal structure between SLNs with and without black cumin seed oils. SLNs system has a potential to show a high stable loading capacity of active lipophilic compounds. [ABSTRACT FROM AUTHOR]

Malaria in Indonesia exceeds more than 300.000 cases in two consecutive years since 2016. Recently, a synthetic drug called chloroquine was used for the treatment. Unfortunately, the massive consumption of chloroquine gives rise to Plasmodium resistance. This research aims to determine the potency of endophytic bacteria obtained from cinchona plants root producing quinine compound and characterize its morphological properties. Quinine extraction starts with bacterial cultured in 7 mL Nutrient Broth inside vial supplemented with 140 µL (1:20) tryptophan. All bacteria cultures were incubated at 27 °C and agitated in a shaker with 120 rpm for 48 hours. The extraction process was carried out with additional 8.4 ml (1:1.2) chloroform to each sample. The qualitative measurement uses Thalleioquin test method with hydrochloric acid (HCl), Bromine-solution (KBr + KBrO3 + H2O), and ammonium chloride (NH4Cl) as the main reagent. This screening test indicator is the color in the upper phase of the sample compared with the Green-Yellow color (5GY 8/6) from Munsell Color Chart. We found all isolates could produce quinine, and isolate a11 and a13 has the highest color strength. Both isolate a11 and a13 are classified as negative Gram, non-capsulated, and bacilli shape properties. [ABSTRACT FROM AUTHOR]

Metro River is one of the rivers in Malang city that still used for bathing and washing by the local community. Waste from household activities and agricultural waste is directly discharged into waterways, triggering water pollution. This study aims to determine the water quality of the Metro River based on the diversity of macrozoobenthos. The physicochemical factors are also measured, including temperature, pH, DO, and BOD.

A coral skeleton is one of the biomonitoring agents that is useful to consider the seawater's situation pollutant. It can record contaminants' reconstruction and predict pollution history, especially of Fe3+ and F− ions as the pollutant in the seawater. We investigated Fe in the coral skeleton and added F− ions in seawater as the reconstruction of polluted F− ions. Fluoride content in coral skeleton was determined as a related Na concentration (NaF) using the Flame of Atomic Absorption Atom (FAAS) with spike method. Fe3+ and F− ions were mixed in the reactor with a coral skeleton to understand their effect on the coral growth. The coral absorbs F− ions in the coral growth with their effect on Fe's absorption rate. The addition of 1.5 g/L F− ions significantly reduces the coral growth by 25%. The coral skeleton can be used to control Fe and F− in the seawater. [ABSTRACT FROM AUTHOR]

High salt-tolerant extracellular protease is an enzyme that plays a crucial role in industries and requires high salt conditions. Some protease enzymes are not resistant to high salt conditions because they may denature under high salt concentrations. Halophilic microbes produce extracellular enzymes that are stable at high salts. This research has succeeded isolating several halophilic microbes capable of producing extracellular proteases from Bledug Kuwu, Grobogan, Central Java, Indonesia. Extracellular proteases producing bacteria screened with skim milk selective medium and purified with the quadrant streak method. Then, the pure isolate and the resulting extracellular protease were characterized BK1B isolate was a Gram-positive bacterium, while BK1D was a Gram-negative bacterium. BK1B isolate is a halotolerant bacterium and BK1D is a moderate halophilic bacterium. BK1B and BK1D had the largest proteolytic index values, capable of producing extracellular proteases with an optimal production time of three days and pH 6. Extracellular proteases from BK1B and BK1D worked optimally at pH 6 and temperatures of 45 and 42 °C with 2.541 and 3.505 U/mL activity and resistance to NaCl concentrations ranging from 3 - 13% NaCl. This suggests that extracellular proteases from BK1B and BK1D strains can be stable at high salt concentrations. [ABSTRACT FROM AUTHOR]

Environmental pollution is a complex problem because waste is generated in all areas of life. If not handled properly, laboratory waste can pollute and endanger the environment. Laboratory waste containing heavy metals such as Cadmium, Chromium, Nickel, and Zinc is hazardous if it pollutes the environment. An easy and inexpensive method of treating heavy metal waste is adsorption. This research applies silica-cellulose material as heavy metal adsorbent in laboratory waste. Variations in contact time were used to measure the adsorbent capacity and adsorbent effectiveness on heavy metals Cadmium, Chromium, Nickel, and Zinc. The results showed that the contact time affected the adsorption capacity and the adsorption effectiveness of silica-cellulose on heavy metal content in laboratory waste. For Cd and Zn metals, the highest adsorption capacity at the contact time of 1 h with adsorption effectiveness values above 90%. Whereas for Cr and Ni metals, the highest adsorption capacity was at the contact time of 3 h with different values of adsorption effectiveness. For Cr metal, almost entirely can be absorbed well, while Ni metal is only half of the total metal can be absorbed. [ABSTRACT FROM AUTHOR]

The Covid-19 pandemic, which is happening all over the world, needs serious attention. Covid-19 initiated by an RNA type virus can cause more severe problems later on due to its ability to mutate. Integrated molecular research is required to determine the characteristics and potential of various variants of Covid-19 in mutations. This study was conducted by directing phylogenetic analysis on 17 samples of Covid-19 sequences from several countries taken from the NCBI database and followed by ORF analysis of each Covid-19 sample for further characterization. Based on the study, it is known that from 17 samples of Covid-19 sequences, Covid-19 sequences from Taiwan have the lowest similarity compared to 16 other Covid-19 sequences. These results are confirmed by the ORF analysis of each sample, which shows that the longest ORF in the Covid-19 sequence from Taiwan is an ORF 20 with lengthened by 4405 amino acids, and the shortest ORF is an ORF 38 with lengthened by 50 amino acids. However, 16 other sequence samples have the longest ORF 6, ORF 6, with lengthened by 4405 amino acids and the shortest ORF 44 with lengthened by 50 amino acids. The difference in ORF variation affects the similarity level of Covid-19 sequences from several countries. It is due to variations in ORF that produce amino acid variations that determine the Covid-19 phenotype. [ABSTRACT FROM AUTHOR]

Rheumatic heart disease (RHD) is recognized as a heart disease resulting from sequelae in acute rheumatic fever (ARF), mostly manifested in mitral regurgitation. PINP and PIIINP play an important role in triggering the remodeling process. This is a cross-sectional study. Forty RHD patients underwent echocardiographic examinations to be classified into ARF without valve abnormalities, mild, moderate, and severe mitral regurgitation. PINP and PIIINP through venous blood and ELISA were examined. The result shows a significant PIIINP level and ratio PIIINP/PINP difference between the mild and severe MR groups (p = 0.020 and p = 0.026) with insignificant PINP levels. According to the correlation test, there is a correlation between the level of PIIINP and the degree of mitral regurgitation severity (p = 0.018) with (r = 0.372) while PINP dan PIIINP/PINP ratio is insignificant. According to the study, the PINP level is indicated insignificant, but PIIINP levels and PIIINP/PINP ratio show that in RHD, children with the severe form of mitral regurgitation are significantly higher than mild regurgitation group. Thus, there is a correlation between the PIIINP level and the degree of mitral regurgitation severity in children in RHD. [ABSTRACT FROM AUTHOR]

This paper is a product of the authors' intellectual restlessness related to the reality that Indonesia still has a continuous problem of environmental destruction despite being a Muslim majority country. It does not align with Islamic teachings, especially knowing that Islam is a religion paying the most attention to the environment. Yūsuf Al-Qarḍāwy, through his book Ri'āyat al-Bī'ah fi Sharī'ah al-Islām, affirmed that Islam is an eco-friendly religion, using maqāṣid al-sharī'ah as the method of approach. There are three main problems discussed in this work. Firstly, Yūsuf al-Qardhawy's view on environmental ethics in Ri'āyat al-Bī'ah fi Sharī'ah al-Islām and his idea on hifdh al-bī'h as a part of maqāṣid al- sharī'ah. This research fell under the subject of normative law and thus it is categorized as library research based on the method used in gathering the data. The primary and secondary data were analyzed using the descriptive-analytic method. There are three findings highlighted in this work. Firstly, there are five basic principles of environmental ethics defined by Yūsuf Al-Qarḍāwy: the principle of respect, love and affection towards nature, responsibility, simplicity, and justice. Secondly, Yūsuf al-Qardhawy's concept of hifdh al-bī'ah is a medium to actualize kulliyāt al-khams. [ABSTRACT FROM AUTHOR]

Observation of agronomic traits is crucial in plant breeding programs to develop high yielding varieties. High yielding varieties can be a solution for the low productivity of domestic soybeans. This study aimed to determine the agronomic traits of F3 generation soybean derived from high yielding small-seeded soybean genotype (UM 6-1) with large-seeded soybean variety (Grobogan). The agronomic data were analyzed using principal component analysis and cluster analysis. The highest influential characters were the seed yield per plant and the number of seeds per plant based on the first and second main components. The number of unfilled pods was the least prominent because its contribution to the main component was smallest than other characters. Plant height, number of branches, number of productive nodes, number of filled pods, number of seeds per plant had a similar contribution to the population structure. The UM 6-1/Grobogan lines were divided into 5 clusters. Cluster 1 did not have a character with high value. Cluster 2 had a high number of unfilled pods and 100-seed weight. Cluster 3 had high 100-seed weight. Clusters 4 and 5 had high values for six characters. Every cluster is attributed to some dominant characters that developed the cluster. [ABSTRACT FROM AUTHOR]

Keratinase is a specific proteolytic enzyme that degrades keratin. Keratinase has wide applications in global industries. Bacillus sp. MD24 has been reported to produce keratinase by solid-state fermentation method using chicken feathers as a sole substrate. Furthermore, keratinase production could be elevated by adding biomass waste (sugarcane bagasse, tofu waste, or rice husk) to chicken feathers. However, the ratio of biomass waste addition was unknown. The liquid by-product of keratinase production contains both carbon and nitrogen sources, which is potential as organic fertilizer. This study aimed to determine the effect of chicken feathers and an additional carbon source ratio toward keratinase production by Bacillus sp. MD24 and potential of its liquid by-products as organic fertilizer. This research was conducted in several stages: keratinase production, enzyme assay, testing liquid by-product on the growth of caisim, and plant morphological analysis. The results showed that the addition of tofu waste produced higher keratinase compared to other carbon sources. The optimal ratio between chicken feathers and tofu waste to produce optimal keratinase was 1:0,4 on the 6th day. Growth rates, the number of leaves, and chlorophyll a and b pigments increased significantly with 20-days irrigation at 1:5 and 1:10 (v/v) dilution. [ABSTRACT FROM AUTHOR]

FTIR characterization shows the bond -CH-(CH2) with an asymmetric vibration model that experiences a shift in the peak vibration on the magnetic fluid sample, and it is a representation presence of oleic acid as one of the substances in the VCO surfactant. Furthermore, a new peak with the -COO- bond shows carboxylic acids as evidence of the combination of symmetrical bonding with surface molecular bonds. This indicates that the addition of VCO surfactants can reduce the agglomeration of magnetite nanoparticles. To determine the Specific Absorption Rate (SAR) value we used magneto-thermal characterization. From the analysis, SAR value of magnetic fluid indicates 1.659 and 2.021 W/g for the Fe3O4/VCO ratio of 1 : 3.5 and 1 : 4.5, respectively. From these results, the magnetic fluid of Fe3O4/VCO is a potential candidate as a material for hyperthermia therapy. [ABSTRACT FROM AUTHOR]

Nicotine dependence can cause numerous adverse effects, especially cardiovascular, cancer, respiratory, and gastrointestinal diseases. In order to minimize the manifestation of nicotine, inhibition on the receptor's binding site is needed. Our previous in silico study shows the activity of several bioactive compounds from Camelia sinensis, Orthosipon aristatus, and Moringa oleifera might be potent as α-3 nicotinic acetylcholine receptor. Thus, in this present study, we extend the screening of inhibitor potency from Kaempferia pandurata, Camelia sinensis, Centella asiatica, Moringa oleifera, and Orthosipon aristatus bioactive compounds against the α-2 NAchR. In silico approach was performed to screen and predict the possibility of drug-likeness and medicinal plant properties of bioactive compounds. The 2D and 3D structures of ligands and protein were retrieved from PubChem and SWISS Model, respectively. The molecular docking strategy and optimization, also visualization were occupied as our previous study. The present findings show that the bioactive compounds from K. pandurata, C. sinensis, C. asiatica, M. oleifera, and O. aristatus have the possibility to be potential α-5 NAchR inhibitor.

Gout and COVID-19 have been of global concerns. One of the drugs for gout is allopurinol that acts as a xanthin oxidase inhibitor (XOI). However, this drug has side effects, so we need safer drugs from herbal sources such as sugar apple. Sugar apple ethanol extract can act as XOI, but the activity of steeping with hot water is not known. Besides, several sugar apple compounds are also reported to be active as anti-viruses, but their activity has not been categorized against the COVID-19. This study aimed at making powder from sugar apple, which was brew using hot water, determined the phytochemical content, including TPC and TFC, tested its activity as XOI and the profile bond of the active compounds to the S protein of COVID-19. The results showed that the extract of sugar apple powder contained alkaloids, flavonoids, polyphenols, with TPC and TFC levels of 0.048% and 0.099%, active as XOI. Furthermore, the in silico analysis has shown three compounds in sugar apple, namely quercetin-3-glucoside, rutin, and kaempferol-3-rutinoside that can bound to the RBD of S protein of COVID-19, so it is predicted that the three compounds have anti-COVID-19 activity.

Non-alcoholic fatty liver disease (NAFLD) occurs when triglycerides inside hepatocytes are swollen. A single bulb garlic extract containing allicin components, S-allyl-l-cysteine, Ajoene (E-Ajoene and Z-Ajoene) are thought to inhibit fat biosynthesis and reduce triglycerides in blood serum. This study aimed to analyze single bulb garlic extract in NAFLD due to a high-fat diet (HFD) in mice. Twenty male Balb/C mice were divided into five groups: normal, HFD, HFD + Single Bulb Garlic Extract (SBGE) 100 mg kg BW−1, HFD + SBGE 200 mg kg BW−1, and HFD + SBGE 400 mg kg BW−1. The administration of SBGE orally altogether with HFD for 30 days. On the last day of treatment, the mice were sacrificed. The liver was collected to make a micro-anatomic slide and stained by Hematoxylin Eosin. Liver microanatomy slides were observed under a light microscope and scoring to count fatty liver cells. The results of this study indicated that administration of SBGE affected the average liver weight (p < 0.05). Treating SBGE with dose of 100 mg kg BW−1, 200 mg kg BW−1, and 400 mg kg BW−1 decreased hepatic steatosis (p < 0.05). SBGE could prevent non-alcoholic fatty liver disease in mice fed with HFD.

Oxidative stress is a state of imbalance of free radicals in the cells and is one of the causes of various diseases in humans. One method that is thought to reduce oxidative stress is calorie restriction or fasting. However, its effects remain unclear. This study was conducted to determine the effect of intermittent fasting and prolonged fasting on the levels of malondialdehyde (MDA) as an oxidative stress marker in the liver and plasma of New Zealand White rabbits. Fifteen of New Zealand White rabbits were divided into three groups (intermittent fasting (IF), prolonged fasting (PF), and control). MDA was measured in plasma and liver homogenate using spectrophotometry. The results were analyzed using One-way ANOVA test. The liver MDA level was decreased in the IF group, but not significant. However, there was a significant increase in plasma MDA levels both in the IF and PF groups. Moreover, liver MDA level was increased in PF group, although it was not significant. In conclusion, intermittent and prolonged fasting could increase plasma MDA levels significantly. [ABSTRACT FROM AUTHOR]

We considered a mathematical model of the spread of the HIV-AIDS (Human Immunodeficiency Virus - Acquired Immunodeficiency Syndromedisease). The model is of the type of SIA (Susceptible, Infected, AIDS cases). The total population was subdivided into three compartments, that is, S (Susceptible group), I (Infected group) and A (AIDS cases group), as the name suggests, in order to form the SIA model. We used the fourth order Runge-Kutta method for solving the model. We took secondary data available in the literature for parameters and initial conditions that we used in our simulations. The resulting Runge-Kutta solutions provided behaviour and prediction of the spread of the HIV-AIDS disease. [ABSTRACT FROM AUTHOR]

Ladybugs "Oteng-oteng" (Epilachna sparsa) are often found in eggplant fields and eat eggplant leaves. This condition causes stunted growth of eggplants and material loss for farmers. Although quite effective, synthetic pesticides can pollute the environment, be resistant to the pest, and harm human health. To overcome it, natural pesticides or biopesticides are used. Citrus hystrix leaves is one of plants used as antifeedant. This preliminary study aims to determine effectiveness of Citrus hystrix leaves extract as antifeedant against Epilachna sparsa. GC-MS analysis showed the presence of farnesol, caryophyllene oxide, nerodilol, citronellol, and citronellal as known insect repellents. The chloroform extract of C. hystrix leaves was smeared on the eggplant leaves, observed for 3 days, and analyzed to know the effectiveness of the treatment. As a result, the C. hystrix leaves extract was less effective of being used as an antifeedant against E. sparsa with eating inhibition value (%PM) of 32.35% based on the weight of the leaves eaten by E. sparsa.

Foraging behaviour of snake can be distinguished by their environments to be an aquatic, semi-aquatic, terrestrial, or fossorial snakes. Here, we recorded not only a foraging behaviour of water snake but also other snakes that have habits to be near the water sources. Snakes at seven water sources in Malang are identified and grouped into Colubridae Family and Elapidae Family. Water snakes are usually found hang on branches and wide leaves over the slowly-flowed stream. We found a Fowlea melanzostus that active during the day, and eating Fejervarya limnocharis. The most common species was Fowlea melanzostus piscator and it is active during the day and night. Two of the four species found are arboreal snake, they are Dendrelaphis pictus and Ahaetulla prasina. Both arboreal snakes are found not only during the night but also during the day. We found one individual of Ahaetulla prasina that was hanging on a bamboo stick while eating Chalcorana chalconota during the day. Most of the water sources in Malang have been dominated by Chalcorana chalconota. It makes Bungarus candidus and Coelognathus flavolineatus also found within this ecosystem. Besides preying on the frog, this snake also preys other's snake and mouse which are also found in nocturnals. [ABSTRACT FROM AUTHOR]

Streptococcus agalactiae is a gram-positive bacterium which has pili protein on its cell surface. It can cause pathogenic infections in the reproductive tract of women and newborns, resulting in premature births, meningitis, and pneumonia. Streptococcus agalactiae samples obtained from patients treated at Saiful Anwar Hospital Malang, East Java, Indonesia. Streptococcus agalactiae were cultured using biphasic brain heart infusion (BHI). The subjects were divided into 4 samples namely, the first pili cut sample, the second pili cut sample, the third pili cut sample and the whole Streptococcus agalactiae cells sample. Each group was tested for hemagglutination and SDS-PAGE electrophoresis. The analysis test result was seen based on the agglutination and the dominant color of the protein band using the EZ Gel-Biorad Gel Documentation System tool. The hemagglutination test showed that the second cut of Streptococcus agalactiae pili had the highest positive hemagglutination test at dilution of titer 64 (1/64). The SDS-PAGE electrophoresis test showed that the dominant bands were in the second pili cut sample at 35 and 53 kDa molecular weights. The pili Streptococcus agalactiae has high hemagglutination activity and dominant molecular weight, which can be used as vaccine candidates. [ABSTRACT FROM AUTHOR]

Bacterial Leaf Blight (BLB) is a severe disease that reduces rice crop yields. It is caused by Xanthomonas oryzae pv oryzae (Xoo). The BLB disease can be manage through some ways, such as the adoption of BLB resistant varieties. It is necessary to investigate this disease because of the BLB outbreak cases in several regions in Indonesia, especially in West Java as the center of rice production. This study aimed to identify the Xoo from ten districts in West Java by applying diagnostic molecular markers for Xoo (XO, Xoo4009, and Xoo2976) using colony PCR and assess the virulence level of in vivo pathogenicity test using resistant varieties (IRBB7 and Conde) and susceptible varieties (IR64 and TN 1). The bacterial isolation resulted 50 isolates and detected four positive Xoo isolates i.e. Xoo-6 (Cicalengka, Bandung), Xoo-17 (Sindang Karya, Karawang), Xoo-19 (Rawamerta, Karawang), and Xoo-21 (Teluk Jambe, Karawang) and showed 98% similarities. The highest level of virulence of isolates was found in Xoo-6 and the lowest level was found in Xoo-21 isolates. The BLB disease intensity in the vegetative phased plants was higher than generative phased. [ABSTRACT FROM AUTHOR]

The consumption of LCS in Indonesia was recorded at 1,100,000 million tons in 2018. The decrease in the corrosion rate is inhibited by the lignin-inhibition method. This study was conducted on the effectiveness of Borassus flabellifer fiber lignin extract as a green inhibitor of corrosion in LCS. Literature review using relevant articles based on bibliometric and molecular designs simulation method omits was used. The molecular design simulation shows that inhibition of LCS by lignin occurs through an electron exchange reaction between oxygen atoms in aromatic rings of lignin and the d-orbitals of Fe atoms on the LCS surface in acidic media. The lignin coats LCS and blocks oxygen atom from direct contact, so the corrosion rate decreases by up to 37.5% compared with untreated LCS. Borassus flabellifer fiber is widely distributed in Indonesia that is not utilized and rich in lignin content. It is estimated that 93,000-186,000 tons of Borassus flabellifer fiber are produced 17,670-35,340 tons of lignin every day, which can coat 476.16-952.32 million m2 LCS. This is high to be developed as a prevention method of LCS corrosion in the future because of (1) high raw material reduction, (2) high lignin extraction product from Borassus flabellifer fiber, (3) inhibitor application in LCS, and (4) its inhibitory power against high corrosion rates.

Tuberculosis (TB) caused by infection of Mycobacterium tuberculosis (MTb) has a complex immunological response that leading to a variety of lung pathology, as reflected on Chest X-ray (CXR) imaging. Tumor Necrosis Factor- a (TNF-α) and Interleukin-17 (IL-17) are also pro-inflammatory cytokines secreted as a response of MTb infection. Both have pleiotropic effects and excessive expressions are associated with lung damage. This study aims to determine the correlation between levels of TNF-α and IL-17 based on lung damage from CXR in paediatric TB. This is a cross-sectional study. The subjects include 38 TB patients divided into 3 groups; mild, moderate, and severe lung damage based on CXR, from January 2019 to July 2020. Plasma TNF-α and IL-17 levels measured using ELISA then compared to each group. There is a significant difference in TNF-α levels between mild vs moderate (p = 0.002), mild vs severe (p = 0.000), and moderate vs severe lung damage (p = 0.001). A positive correlation was also found between TNF-α levels and lung damage (p = 0.000, r = 0.796), whereas IL-17 shows no significant difference (p = 0.538). Increasing TNF-α level, but not IL-17, is associated with severity of lung damage in paediatric TB. [ABSTRACT FROM AUTHOR]

The result shows that from 50 calluses infected sprout up 42 calluses in hygromycin selection, 35 calluses regenerate into shoots and 20 plantlets. The calculation of transformation efficiency is 84%, while regeneration efficiency is 83%. Confirmation of Beag ganggas OsMADS18 is used hptII primer and OL13/14 primer, which produces 500 and 742 bp DNA fragment constitutively. So that, OsMADS18 has been successfully inserted in Beak Ganggas genome using Agrobacterium-mediated transformation. [ABSTRACT FROM AUTHOR]

Hyperglycemia is the main hallmark of DM, which is caused by elevated levels of Advanced Glycation-End Products (AGE) and Receptor for AGE (RAGE) interaction. AGE-RAGE interaction further develops a progressive diabetic complication due to excessive free radical production. Hydrogen-rich water (HW) are known to have a beneficial effect on health as an antioxidant and anti-inflammation. The objective of the study was to investigate the effect of HW on the AGE-RAGE expression in streptozotocin (STZ)-induced diabetic rats. Rats divided randomly into five groups: N (healthy rats); DM (STZ + High-fat diet (HFD)) without additional treatment); DM + Met (DM + metformin dose 45 mg/kg BW); DM + HW (DM + Hydrogen-rich water); and DM + MH (DM + combination metformin and hydrogen-rich water). Rats were treated with HW or metformin for fourteen days and given per orally per day. At the end of treatment, rats were sacrificed and the pancreas was collected. AGE-RAGE expression was determined using the immunohistochemistry method. Our result suggested that either HW or HW combined with metformin declines AGE-RAGE expression significantly (p < 0.05) compared to DM rats. HW is expected to delayed organ damage by improves AGE-RAGE expression in STZ-induced diabetic rats. [ABSTRACT FROM AUTHOR]

Lipase is an industrially important enzyme and is usually obtained from microorganisms, especially filamentous fungi, producing it in a high amount. The method commonly used to produce lipase from filamentous fungi is Submerged Fermentation (SmF) with agitation. However, agitation requires energy and high production cost. Hence, reducing the use of agitation is needed. This research aims to observe the influence of agitation speed toward colony growth, lipase productivity, and nutrient absorption from Indonesian Aspergillus aculeatus Ms.11 in broth medium. Aspergillus aculeatus Ms.11 was inoculated into 50 mL fermentation medium, which contains 1% of olive oil and glucose mixture with 1:1 comparison. Incubation was done using varied agitation speed (0, 50, 100, 150, and 200 rpm) at 30 °C for 96 h. Relative activity lipase productivity, enzyme-specific activity, and glucose and nitrogen consumption were determined after the incubation. The results show that the highest lipase activity (6.33 U/mL) and lipase specific activity (0.10 U/mg) are observed at 0 rpm, while the highest lipase productivity (0.43 U/mg) is observed at 50 rpm. We concluded that maximum lipase production from Ms. 11 can be obtained using low agitation speed. Further study to optimize carbon and nitrogen sources is suggested. [ABSTRACT FROM AUTHOR]

Hypertension is a high risk of heart disease and stroke, which is caused by vasoconstrictive arteries due to angiotensin II binds to angiotensin II type 1 receptor (AT1R). Treatment of hypertension using the drugs angiotensin receptor blockers (ARBs) causes side effects of headaches, constipation, and diuretics. Phenolic compounds (10-gingerol, 8-gingerol, 6-gingerol) from red ginger (Zingiber officinale var. rubrum) were used for hypertensive herbal medicines. This study aims to predict the potency of 10-gingerol, 8-gingerol, 6-gingerol as AT1R antagonist by bioinformatics approach. This research was conducted using physicochemical properties, Pa test, pharmacokinetic test, and molecular docking of the three gingerol compounds and Losartan as drug control. The results show that 10-gingerol, 8-gingerol, 6-gingerol have good oral bioavailability, good vasodilator potential (Pa >7), hepatoprotective potential, vasoprotective potential, and antioxidant potential. Based on pharmacokinetic absorption, distribution, and excretion test, the three gingerol compounds showed higher results compared to the Losartan. The toxicity of the gingerol compounds is low, not hepatotoxic, whereas Losartan is hepatotoxic. Molecular docking showed that the three gingerol compounds and the Losartan were on one side of the binding to AT1R. The conclusion of this study is red ginger has potency as a candidate for oral drug hypertension. [ABSTRACT FROM AUTHOR]

Recently, no anti-fibrotic agents work effectively to suppress fibrosis process because of its complex pathophysiology. Moringa oleifera (MO) has been shown to function as anti-inflammatory and anti-fibrotic agent through inhibition of NFĸB cascade pathway. This study was conducted to prove the anti-inflammatory and anti-fibrotic effects of MO for inhibit liver fibrosis process through an expression of TNF-α and p38-MAPK.

Diabetes Mellitus (DM) and COVID-19 diseases are still global problems. One of the causes of DM, mainly type 2 is unhealthy eating habits, including white sugar, which contains almost no active compounds except sucrose. The active compounds in sugarcane juice such as ferulic acid, gallic acid, 4-Hydroxy benzoate acid, and vanillic acid, which are suspected besides alpha-amylase inhibitors, also have potential as anti COVID-19. The purpose of this research is to extract secondary metabolites from sugarcane juice, determine TPC and TFC, and to know in silico activity of the active compounds in sugarcane juice as an alpha-amylase inhibitor and binding position to the active site of the spike protein. The results have shown that TPC and TFC in sugarcane juice are 0.5501% and 0.4480%. The in silico analysis has proven that the ferulic acid compound is bonded to the alpha-amylase binding site as acarbose did. Gallic acid, 4-hydroxy benzoic acid, and vanillic acid compounds are bonded to RBD of S protein COVID-19 as chloroquine did, with various binding affinity. These results indicate that phenolic and flavonoids in sugarcane juice have the potential as an alpha-amylase inhibitor and anti COVID-19. [ABSTRACT FROM AUTHOR]

The characteristics of yogurt are influenced by the concentration of the starter and incubation time. This study aims to determine the effect of variations in starter concentration and incubation time on the characteristics of yogurt. To achieve this objective, the study was carried out through several stages, namely sample preparation (pasteurization of cow's milk); incubation of cow's milk yogurt with variations in starter concentration and incubation time; characterization of the physical and chemical properties of yogurt. The physical properties were investigated through organoleptic tests of color, aroma, taste, and texture, along with pH and viscosity tests. In contrast, the chemical properties were analyzed from the total acid levels and protein levels. The results show that the variation in the treatment of yogurt production significantly affects the physical and chemical characteristics of the yogurt produced. The produced yogurt's pH is in the range of the standard value set by Food Standards Australia New Zealand (FSANZ). Besides, the amount of produced yogurt's total acid and protein concentration in this study are also met in the standard value set by the Indonesian national standard of yogurt. Moreover, the Mann-Whitney test results show excellent characteristics of yogurt produced. It has a soft texture, a distinctive aroma of yogurt, sour flavor, and white color. [ABSTRACT FROM AUTHOR]
