Publisher : Postgraduate School, Universitas Brawijaya

In this paper, optimal control of tumor growth model with dendritic cells as immunotherapy is provided. The model equation can be expressed into a nonlinear differential equation system consisting of four compartments namely, tumor cells, CTL cells, helper T cells, and dendritic cells. Dendritic cells as immunotherapy are injected to the body at time t. The aim of this optimal control is to minimize the tumor cells density as well as the cost of dendritic cells to be administered to the body.Optimal control problem is carried out based on Pontryagin's maximum principle and numerical simulation is solved by using Forward-Backward Sweep methods. Simulation results show that control strategy shrinks tumor cells density which is shown by tumor cells density graph that monotonically decreases after applying dendritic cells as immunotherapy.Keywords: immunotherapy, optimal control, Tumor cell.

In Indonesia, the prevalence of diabetes mellitus hits 6.2%, making Indonesia one of the top ten diabetes mellitus countries. Efforts to prevent and treat people with diabetes in Indonesia are required to minimize that as well. One is through treatment with local herbal products such as Moringa oleifera (MO) and Toman fish extract (Channa micropeltes), called Ifalmin. The aim of this research is to investigate the potential role of a combination of Extract Moringa oleifera and Ifalmin to reduce inflammation in diabetes conditions. Diabetic mice were done by Streptozotocin (STZ) induction with a single-dose 145 mg.kg-1.Then, diabetic mice were given an oral treatment of combination MO extract and Ifalmin for 14 days. In this experiment combinations of MO extract and Ifalmin are divide into 3 dose, There are: dose 1 (800 mg.kg-1 : 800 mg.kg-1), dose 2 (650 mg.kg-1 : 650 mg.kg-1), and dose 3 (800 mg.kg-1 : 650 mg.kg-1). Immune cells originate from the spleen are stained by immunofluorescence antibodies and analyzed by flow cytometry with BD Cellquest ProTM software. The results showed an increase of expression pro-inflammatory cytokines IL-1β and IL-6 in diabetic mice compared to normal control. Only dose 1 and dose 2 has shown the capability to reduce the expression of IL-1β in diabetic mice. But, the combination of MO and Ifalmin has an antagonist effect on the expression of IL-6. The inhibitory mechanism can be assumed by the action of antioxidant compounds (Flavonoids and Alkaloids) in MO and Albumin compound in Ifalmin. Those combination act as exogenous antioxidant that help endogenous inside the body. A combination of MO extract and Ifalmin with a certain dosage was able to decrease proinflammatory cytokines IL-1β on the cells involved in innate immunity.

The goal of this research was to evaluate the effect of colchicine on the formation and growth of shoot from explant crowns by in vitro, as well as to obtain polyploidy vetiver plant (Vetiveriazizanioides L. Nash). Induction of polyploidy vetiver plants carried out by culturing explant crowns on MS media supplemented by 2 mg.L-1 BAP and colchicine (0, 30, 60, 90, 120 mg.L-1) for three weeks. Explant and formed shoot regenerated on MS media containing 1 mg.L-1 NAA. The generated plantlets acclimatized on the growing media (cocopeat: husk charcoal: compost = 1: 1: 2). Plant ploidy level of the plants regenerated from treated explant estimated by chromosome counting in root tips. The effect of colchicine on media was able to induce polyploidy in vetiver plants. Five mixoploids were obtained from explant treated colchicine. The vetiver mixoploid plants obtained were 20% and 62.5% from colchicine 60 mg.L-1 and 90 mg.L-1, respectively. The vetiver mixoploid plants consist of diploid (2n=2x=20) and triploid cells (2n=3x=30) or diploid (2n=2x=20) and tetraploid (2n=4x=40). The addition of colchicine in concentrations above 30 mg.L-1 caused inhibition of shoot formation and growth, even a concentration of 120 mg.L-1 caused explant death. However, 30 mg.L-1 colchicine could increase the number of formed shoots, while only 60 mg.L-1 and 90 mg.L-1 could be induced the mixoploidy in the vetiver plant. The results showed that colchicine treatment could increase ploidicity in vetiver plants in vitro, but caused inhibition of shoot formation and growth. Keywords : Chromosome, colchicine, in vitro, polyploid, Vetiveria zizanioides L. Nash.

It has been known that the immunoglobulin levels were altered in diabetes mellitus (DM) conditions. This study aimed to evaluate the levels of immunoglobulins in DM mice after the administration of Moringa oleifera-Ifalmin® formulation (MI). Streptozotocin, at a dose of 145 mg.kg-1, was injected intraperitoneally to experimental mice to obtain diabetic mice. The groups were divided into normal mice, diabetic mice without treatment, diabetic mice with metformin treatment (307.5 mg.kg-1 BW), and diabetic mice with MI treatment at dose 1 (M:I= 800 mg.kg-1 BW: 800 mg.kg-1 BW), dose 2 (M:I= 615 mg.kg-1 BW: 615 mg.kg-1 BW), and dose 3 (M:I= 800 mg.kg-1 BW: 615 mg.kg-1 BW). Mice were orally treated by MI for 14 days. Subsequently, the levels of immunoglobulin IgM and IgG were evaluated using flow cytometry analysis. IgM and IgG levels were significantly lower in the DM group than the normal group. These results indicated that DM altered immunoglobulin levels. MI treatment for 14 days significantly increased the number of IgM and IgG at the level equivalent to the normal group and significantly different as compared to the DM group. Based on the results, MI can be used as an immunomodulatory agent in humoral immunity through the precise regulation of IgM and IgG.

This study had purpose to determine the glucomannan and calcium oxalate content in 7 variants of A. variabilis and their genetic relationships based on RAPD markers. Amorphophallus variabilis Tuber samples were taken from Karangdowo village, Sumberrejo Sub-district, Bojonegoro District, East Java. Each variant was analyzed for its glucomannan content by the spectrophotometric method using 3,5-DNS reagents and calcium oxalate by the 0.1N KMnO4 titration method. Leaf DNA extraction was carried out using the CTAB method. Relationship analysis used RAPD markers with 5 primers (OPA-11, OPC-04, OPU-06, OPC-07, and OPN-1). The obtained data were analyzed using the Numerical Taxonomy and Multivariate System (NTSYS-pc) version 2.1. The grouping of glucomannan content or oxalium oxalate used hierarchical clustering analysis (SPSS 16.0). This research found that the calcium oxalate content in seven variants of A. variabilis ranged from 0.01 to 0.03 g, where the variant with the lowest calcium oxalate is V6 with a value of 0.01 g and the highest is the V7 variant with a value of 0.03 g, while the glucomannan content ranges from 9 - 38%. The highest glucomannan content is V3, while the lowest is V6. Phenograms formed based on RAPD markers showed the formation of two groups of A. variabilis. Group one has two subgroups. Subgroup one consists of variants V1 and V4, while subgroup two consists of V6 and V7. Meanwhile, the second group consists of variants V2, V3, and V5. The seven variant grouping pattern of A. variabilis based on RAPD markers has no similarity to the grouping pattern based on the results of glucomannan or calcium oxalate analysis.

Geranium plant (Pelargonium graveolens L'Her) is one of the geranium oil producing plants that has many benefits. Callus culture is a technique that can be used to plant multiplication and increase production of secondary metabolites. This study aims to determine the effect of the concentration of Benzyl Adenine on the formation of geranium callus from petiole and leaf explants. Callus induction was carried out by culturing petiole and leaf explants on MS medium + 0.1 mg.L-1 NAA + Benzyl Adenine (0; 0.5; 1; 1.5 and 2 mg.L-1). Callus morphological parameters, percentage of callus formation, and time of first callus formation were observed. The formation of geranium callus influenced by the explant type and the concentration of Benzyl Adenine. In the 2nd week, the geranium callus was initiated, light green colored with a compact callus texture. At 4th week, the percentage of callus formation containing NAA 0.1 mg.L-1 of petiole and leaf explants was 20% and 8%, whereas the percentage of callus formation on medium containing 0.1 mg.L-1 NAA combined with 0.5-2 mg.L-1 Benzyl Adenine of petiole and leaf explants was 52-80% and 24-52%. The best percentage of callus formation was found on the culture medium containing 1 mg.L-1 Benzyl Adenine, equaled 80% of petiole explants, and 52% of leaf explants. Keywords: BA, Callus, Leaf, Petiole, Pelargonium graveolens L'Her.
