Abstract

Present investigation shows that the extract of C. aeruginosa attenuates DMBA-induced spleen carcinogenesis in Wistar rats. Three-week female Wistar rats were treated with three different C. aeruginosa extract doses (CA1: 40 mg/200 g body weight, BW; CA2: 80 mg/200 g BW; CA3: 160 mg/200 g BW) and were induced with DMBA after one-week administration of these doses. A commercial immunostimulant, and DMBA only were also given to each group as positive and negative control, respectively. The development of tumors was evaluated by investigating the incidence of tumor and tumor multiplicity during the experiment. Spleen mass index and histological parameters such as white pulp, centrum germinativum, and marginalis zone were also examined. Based on our study, the administration of C. aeruginosa extract during and after carcinogen induction gave several impacts on rat carcinogenesis. At the extract dose of 80 mg/200 g BW, tumor incidence of animals were least (P<0.05). However, all doses did not show any effect to the spleen mass index, though the highest dose (160 mg/200 g BW) was found to cause changes in white pulp and marginalis zone boards. This trend indicates that it takes higher dose to cause an immune response effect reaching the organs.

Abstract

The current interest in exploring white-rot fungi has been concentrated in increasing their ligninolityc enzyme production such as laccase and manganese peroxidase (MnP) due to the great value in industrial application. The presence of appropiate inducers can enhance the enzyme production. Hence, the aim of the study was to investigate the activity of laccase and MnP in response to various aromatic compounds. The fungus Trametes hirsuta was cultured in Glucose Yeast Peptone (GYP) broth (pH 5.0) with the addition of 0.5% of sorghum biomass as substrate. The cultures were then incubated on rotary shaker at 150 rpm at 27oC. The 7-day-old cultures were then supplemented with different aromatic compounds, namely caffeic acid, gallic acid, syringic acid, trans-cinnamic acid, vanillin, and veratryl alcohol. Our results demonstrated that veratryl alcohol, gallic acid and vanillin gave an inductive effect on the value of laccase and MnP activities, with vanillin showing the highest induction. On the contrary, the level of laccase and MnP activities remained low in the presence of aromatic compound such as syringic acid, trans-cinnamic acid and caffeic acid. To conclude, our study reveals that aromatic compounds can be potential as inducers and may contribute to the improvement of laccase and MnP productivity by T. hirsuta.

Abstract

The objective of our present experiment was to investigate the effects of closed pulled straw (CPS) vitrification on the viability and development of mouse embryo. The experiment was arranged according to completely randomized design (CRD) consisting of 4 treatments, namely not vitrification (NV) is control, CPS 1 (mCZB Hepes + 20% Bovine Serum Albumin (BSA) +0.5 M sucrose + 10% EG + 10% DMSO), CPS 2 (mCZB Hepes + 20% BSA + 0.5 M sucrose + 15% EG + 15% DMSO), and CPS 3 (mCZB Hepes + 20% BSA +0.5 M sucrose + 20% EG + 20% DMSO) with 6 replications. The viability of embryos (%) was determined after 24 - 72 h of the culture period, while we also observed the percentage of embryos reaching the blastocyst stage (early blastocyst, expanded, hatching, and hatched). As a result, the treatments did not give a significant difference in the viability of embryos (P<0,05) but showed significant effects on embryo development (P<0,05). Furthermore, this present work conclusively found that CPS vitrification in CZB medium with cryoprotectants ethylene glycol (EG) and dimethyl sulfoxide (DMSO) noticeably influenced the development of mice embryo to reach the blastocyst stage, but showed no remarkable difference in the viability of embryo after culture for 24 – 72 h.

Abstract

Tetrameles nudliflora is one of the endemic plants in Wallace region, especially in Mekongga Forest, Southeast Sulawesi, Indonesia. As part of our project in the field of natural drug discovery based on local bioresources, this study aimed to isolate secondary metabolite compounds from the ethyl acetate fractions of the leaves of T. nudiflora and evaluate their cytotoxic activities against breast carcinoma cancer lines, MCF-7. The methods used were various chromatography techniques such as vacuum column chromatography, gravitation column chromatography, thin layer chromatography, preparative thin layer chromatography, and re-crystallization using two different organic solvents. In the present study, two flavonoid compounds, kaempferol (1) and quercetin (2) were identified. The structures of 1-2 were determined using serial spectroscopic techniques, including mass spectrometry, one- and two-dimensional nuclear magnetic resonance. Moreover, using 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assay method, both compounds showed in vitro cytotoxic activity IC50 of 34.162 and 133.148 μg mL-1, respectively against MCF-7 cell lines.

Abstract

Heading date is one of key traits in rice adaptation to different environments. Rice with early maturity is very useful for increasing rice production extensively especially in Indonesia. The improvement of rice variety Conde for heading date and resistance to bacterial leaf blight (BLB) was developed through Marker Assisted Backcrossing approach (MAB). Xa7 derived from Conde as recipient parents for resistance to BLB and Hd2 gene derived from Nipponbare as a donor parent for heading date. The aim of this research was to evaluate the performance of heading date and agronomic traits of 85 BC2F4 lines in two field stations, Sukamandi (West Java) and Maros (South Sulawesi). Molecular analysis of Xa7 on chromosome 6 and Hd2 gene on chromosome 7 and agronomic performance was evaluated. Foreground analysis resulted 41% for Xa7 and 66.7% for Hd2 gene in homozygous condition. The majority of lines have similar heading date and yield with Conde and more resistance to bacterial leaf blight (BLB) than Conde. Six lines flowered earlier 5 days than Conde in Sukamandi and three lines flowered earlier 3 days in Maros. Twelve lines with flowered earlier than Conde, resistance to BLB and similar yield with Conde were selected for background analysis resulted 93% genome recovery. These lines would be further evaluated in preliminary yield trail for their stability.
