Abstract

The electronic transition processes of α-mangostin and β-mangostin as dye compounds in DSSC and their ability to transfer electrons to semiconductors have been studied in theory. The research was carried out computationally using the NwChem application. The methods used are Density Functional Theory (DFT) for structure optimization and Time-Dependent DFT (TD-DFT) for electronic transitions. The results showed that the energy of HOMO β-mangostin was lower that it was more stable or easier to form bonds with semiconductors. Likewise, its LUMO energy is lower than α-mangostin that it is easier to inject electrons into the semiconductor. The energy difference of HOMO-LUMO β-mangostin is smaller than α-mangostin. This shows that β-mangostin is more easily excited or more efficient in exciting solar energy to convert it into electricity. This is consistent with the molecular spectra where λmaxβ-mangostin is at a higher wavelength. Orbital analysis shows electron injection of α-mangostin and β-mangostin into the semiconductor via double O atoms in each molecule. The injection is influenced by the bond length, where the bond length of α-mangostin to TiO2 is smaller than that of β-mangostin to TiO2.

Abstract

Pectinases are the group of enzymes that degrade pectin. This study was conducted with the aim of isolation of efficient pectinase producing pectinolytic fungi from the decomposing mango peels using extracted mango peels pectin as a growth substrate under submerged fermentation, determining optimum pectinase production conditions with regards to some physicochemical parameters. The organisms were screened for the production of pectinase using Pectin agar media, and the two active pectinolytic fungi (P1 and P2) were isolated. pectinase production media was later used for the Lab scale production of pectinase by inoculating p1 and p2 and incubating for 7 days. The enzyme was extracted after seven days of fermentation and every day tested for their pectinolytic activity. P2 showed relatively higher pectinolytic activity and was therefore used for further studies. P2 was inoculated into a broth containing mango pectin under submerged fermentation. Results indicate that a pectin yield of mango peel 17.75%. Different parameters optimization processes were investigated on submerged fermentation namely pH, incubation period, temperature and substrate concentration optima were found 6, 4 days, 35oC and 1.5% respectively. The result suggests that mango peels have high pectin content and can be used for the value-added synthesis of pectinase.

Abstract

Osteogenesis Imperfecta is a hereditary connective tissue disorder due to COL1A1/2 mutation causing gene defect encoding proteins to metabolize collagen. The skeletal manifestation of OI causing bone incompetence, hence the name brittle bone disease. Here we report three cases of OI type IV in adults. Skeletal conventional X-rays were performed to all patients and all of them has similar results such as bowing deformities of long bones, old union and some non-union fractures with extreme angulation and severe osteoporosis. OI are classified based on skeletal structure, sclera colorization, dentinogenesis, and functional metabolic defect genetically. OI type I and IV can live until adults; also, the same type of OI can be found in siblings. Skeletal conventional X-rays can solely make the diagnosis.

Abstract

Honey and propolis is natural food, produced by honey bees (Apis mellifera) and largely used by the local population for its medicinal properties. Our work aims to extract and evaluate the hydrogen peroxide scavenging capacity of different phenolic extracts from some bee products. Phenolic compounds from honey samples, propolis, and bee pollen were extracted by methanol and subjected to radical scavenging activity towards hydrogen peroxide. The results showed the highest values for the total phenolic and total flavonoïd contents in propolis and bee pollen, and a great hydrogen peroxide (H2O2) inhibition (IC50: 0.205 - 2.210 µg/mL) with honey extracts, while sample “multiflower” is the better antioxidant, more than ascorbic acid used as control. The less scavenging activity was observed with the extract from bee pollen (IC50: 39.383 µg/mL). To combat the harmful effects of free radicals, especially reactive oxygen species including hydrogen peroxide, it is important to use phenolic extracts instead of using honey as it is, and extracts from the honey of different types are excellent antioxidants compared to other bee products.

Abstract

Consumption of liquor such as Ciu in excessive doses can cause a decrease in hematological status. Balimo stem is an alternative treatment to improve hematological status due to excessive alcohol consumption because it contains alkaloids, flavonoids, and other secondary metabolic compounds, that have functions as antioxidant effects. This study aims to examine and analyze the effect of Balimo immersion water on the hematological status of mice with the observed variables, namely the erythrocytes count, hemoglobin levels, hematocrit value, and total count of leukocytes in rats that had been given Ciu. The study used 20 Rattus norvegicus male rats which were divided into 4 groups. The data were analyzed using one-way ANOVA. The results showed no significant differences (p <0.05) on the Balimo immersion water treatment, but if it was seen from the difference in the mean data of each variable, it could still be seen the difference from each treatment. In this study, it can be concluded that Balimo immersion water was able to improve the hematological status of rats that had been given Ciu liquor with a 0,2 mL dose.

Abstract

Availability of quality seeds in production of krisan (Chrysanthemum morifolium Ramat cv Dewi ratih) cultivation is still rare, therefore research on seed multiplication through tissue culture is needed. The media used in tissue culture is relatively expensive for home industry. This study aims to determine the respond of leaf and stem explants using foliar fertilizers (Growmore, Gandasil D and Mutiara) as an alternative media for callus inductions. This study used a Completely Randomized Design (CRD) consisted of 4 treatments: P0: ½ MS + 0,25 mg/l BAP, P1 (Growmore + 0,25 mg/l BAP), P2 (Gandasil D + 0,25 mg/l BAP), P3 (Mutiara + 0,25 mg/l BAP). The variables observed in this study included callus appearance time, callus color and callus texture. The result of this study indicated that the use of BAP (6-Benzyl Amino Purine) affected the time of callus formation and callus morphology. Callus was formed on leaf explants 13 days after planting while on stem explants 7 days after planting and compact texture. Growmore + 0,25 mg/l BAP treatment yields the best callus on leaf explant, while Gandasil D + 0,25 mg/l BAP treatment yields the best callus on stem explant.

Abstract

The low productivity of cocoa plantations in Indonesia is partly due to the low quality of seeds, which refers to the impeded growth of cultivated cocoa nurseries. Seed is the initial growth of plants so the importance of giving special treatment to seeds will refer to better seed growth. Provision of Plant Growth Promoting Rhizobacteria (PGPR) microbes can produce indoleacetic acid (IAA) in plants to improve the quality of plant growth. This study aims to determine the effectiveness of the provision of Plant Growth Promoting Rhizobacteria bamboo rhizosphere against cocoa seed germination. The study was carried out in the farmer group garden, Gantarangkeke District, Bantaeng. This study was arranged in the form of a two-factor factorial design (F2F) in a randomized block design (RBD). The use of cocoa seed type as the first factor consisted of GTB (Gantarangkeke Bantaeng) local cocoa seed and MCC 01 cocoa seed and seed immersion treatment at PGPR rhizosphere bamboo concentration as the second factor consisting of 0% (control) concentration, 5%, 10 % and 15%. The results obtained indicate that administration of seeds with bamboo rhizosphere PGPR affects the germination (100.00%), the speed of seed growth (7.14%/etmal), as well as on abnormal seeds (10.00%). So that the provision of bamboo rhizosphere PGPR on cocoa seeds has an effective influence on seed germination and cocoa seedling development.

Abstract

According to traditional medicine, Hibiscus is used to treat hypertension, heart diseases and many other ailments. Commercially available Hibiscus tea is prepared with H. sabdariffa and is expensive. H. rosasinensis is the common variety which is abundant in tropical home-gardens, however the scientific data are lacking on the effects. The present review focuses on the available scientific data on the effects of H. rosasinensis on controlling diabetes and hypercholesterolemia. The endeavour was to identify whether H. rosasinensis flower petals as a ‘tea’ is effective for diabetic and hypercholesterolemic patients. Medical databases such as MEDLINE, BMC, BMJ, research gate, Mendelay literature search database, Google scholar and the general engine Google were searched from November 2018 to April 2019. Search was carried out using keywords such as “Hibiscus rosasinensis”, “antidiabetic effects”, “antihyperlipidemic effects”, “toxic effects”, “anti-inflammatory effects”, “phytochemicals in Hibiscus” etc. Data were critically analyzed to assess whether the effective doses of the research studies on a par with the doses present in H. rosasinensis teas. We found thirty-nine journal articles fulfilled the criteria. The data were categorized and extracted on uses of H. rosasinensis, anti-diabetic effects, anti-inflammatory effects, anti-hypercholesterolemic effects and its phytochemicals. The review revealed that the dose of H. rosasinensis petals present in a home-made Hibiscus tea is theoretically sufficient to elicit anti-hyperglycemic and anti-hyperlipidemic effects. Home-made Hibiscus tea is effective in controlling diabetes and hypercholesterolemia without causing acute toxicity.
