Abstract

Microalgae are microscopic photosynthetic organisms found in marine and freshwater environments. This organism is a eukaryotic group of polyphyletic and very diverse. This study investigated the biochemical composition and sub-chronic test of Chlorella Sp. and Spirulina Sp. isolated from Glagah coastal water (Yogyakarta, Indonesia) as a preclinical study to create potential nutritional supplement for human health. Microalgae culture was analyzed for biochemical composition using several methods: AAS for metal analysis (Pb, Cu, Fe, Mg, Zn, and Hg), GC-MS and UV spectrophotometer for fatty acid profiles analysis (lenolenic acid, eicosatrienoic acid, arachidonic acid, linoleic acid, oleic acid, eicosenoic acid, EPA, DHA, omega 6 and 9), Alkaloids, Steroids, Tanin and Saponin. The next step is to do a sub-chronic test of microalgae biomass using experimental animals. The result shows that Spirulina sp. and Chlorella sp. contain 16 and 10 different biochemical compounds respectively. Furthermore, organic nutritional properties in both of microalgae are relatively high with a rich biochemical profile of Fe and nutritious poly-unsaturated fats (such as linolenic acid, arachidonic acid , omega 6, and 9). Regarding sub-chronic toxicity test, it was clear that Spirulina and Chlorella did not affect the blood profile. These findings suggest that both of Glagah strain microalgae are considered to have great potential as a multi-nutritional human health supplement.

Abstract

The current high demand for Yellow rasbora (Rasbora lateristriata) is not supported by the availability of captured Yellow rasbora in nature. Aquaculture is the most rational way of utilizing biological natural resources. In intensive aquaculture, it is necessary to optimize all processes that occur in aquaculture, including hatchery. However, the common problem that often happens in hatchery activities is spawning which depends on the season. The hormonal manipulation technique is an appropriate way to stimulate gonadal maturation. Oodev is a hormonal combination of pregnant mare serum gonadotropin and anti-dopamine to stimulate gonadal maturation. The purpose of this study was to determine the effectiveness of using the Oodev with different doses in feed to accelerate gonad maturation of female Yellow rasbora. The study was carried out with four treatments and three replications in 21 days with different doses of Oodev, such as; A (Feed without Oodev), B (0.5 mL/kg feed), C (1 mL/kg feed) and D (2 mL/kg feed). The parameters observed in this study were gonad maturity level, histological structure of ovary, gonadosomatic index, fecundity, and diameter of eggs. The results showed that the dose of Oodev at 1.0 mL/kg feed was an effective dose to optimize the gonad maturity of female Yellow rasbora. This is proven by the highest results shown on all parameters, such as; the maturity level in the IV phase, histological structure of the ovary which showed the dominance of the oocyte maturation phase, gonadosomatic index of 14.014%, the fecundity of 721 eggs, and egg diameter of 0.865 mm. In conclusion, using Oodev in feed at a dose of 1.0 ml/kg of feed for 21 days is an effective dose to optimize the maturation of female Yellow rasbora.

Abstract

Memory formation in mammals involves complex stages, from initial learning to long-term storage. This review highlights key memory-related genes and proteins such as SYNGAP1, Arc/Arg3.1, BDNF, FOXP2, COMT, NR3C1, KIBRA, H-Ras, ERK1/2, and other genes. Mammals serve as important models in memory research due to their evolutionary proximity to humans, providing insights into brain structures such as the hippocampus and prefrontal cortex, which are crucial in memory processes. Molecular mechanisms such as transcription, translation, synaptic plasticity, long-term potentiation (LTP), and long-term depression (LTD), as well as neurotransmitters like glutamate, GABA, acetylcholine, dopamine, and serotonin, are comprehensively discussed with a focus on small, large mammals, and humans. Neurotransmitters affect various functions, including emotion, cognition, memory, learning, and motor functions in test animals. Disruptions in neurotransmitter homeostasis have been linked to numerous neurological and neurodegenerative disorders, highlighting the need to understand the complex mechanisms behind memory in mammals. A brief overview of genes and neurotransmitters related to memory and learning will provide insights and considerations in basic neurobiology and biomedical research.

Abstract

Mangosteen (Garcinia mangostana L.) peel contains bioactive compounds known for their health benefits, yet potential toxicity at certain doses remains a concern. This study evaluates the histopathological effects of mangosteen peel decoction on the liver of Betta fish (Betta sp.), a sensitive model organism. Mangosteen peel decoction was prepared and administered to Betta fish at concentrations of 5, 25, and 50 ppm, with a control group receiving no treatment. Fish were observed for changes in swimming activity and appetite over five days. Liver tissues were collected, processed, and analyzed histologically to assess tissue damage including vacuolization, pyknosis, hemorrhage, and necrosis. Data were analyzed using the Kruskal-Wallis and Mann-Whitney tests. Behavioral analysis indicated a dose-dependent reduction in swimming activity and appetite in treated groups. Histopathological examination revealed significant liver damage across all treatment groups, with higher concentrations of decoction correlating with increased hemorrhage, pyknosis, and necrosis. Vacuolization was highest in the control group and lowest in the 50-ppm group. The overall hepatic damage was categorized as moderate, with the control group showing the least damage. Mangosteen peel decoction induced significant hepatic damage in Betta fish, highlighting the cytotoxic effects at higher doses. The observed behavioral and histopathological changes underscore the need for careful consideration of decoction concentrations to avoid adverse effects in aquatic organisms. This study provides crucial insights into the toxicological impacts of mangosteen peel decoction on fish liver health, emphasizing the importance of dose regulation in practical applications. Further research is recommended to explore protective measures and alternative treatments to mitigate liver damage.

Abstract

Background: Cucumis melo a melon species, typically has a sweet taste. Some cultivars are known for their distinctive bitter flesh due to its higher levels of cucurbitacin. Cucurbitacin is semipolar compound that has anticancer properties. However, the anticancer effects of cucurbitacin from gama melon parfum (GMP) have not been widely studied. The use of n-Hexane as a non-polar solvent in GMP melon fractionation is to dissolve the non-polar parts of the plant. However, Cucurbitacin was found in the n-hexane fraction of Cucurbita pepo L. Therefore, this study will investigate the presence of Cucurbitacin in the n-Hexane fraction and its effects on breast cancer cells T47D and MCF7.Materials and methods: Dry simplicia of GMP melon fruit were macerated using methanol and fractionated using n-hexane. The presence of cucurbitacin was detected using the high-performance liquid chromatography (HPLC) method. Cell cytotoxicity tests were assessed using the MTT assay, with concentrations of 7.8125, 15.625, 31.25, 62.5, and 125 µg/mLResults: Cucurbitacin compounds were detected in the n-hexane fraction at a concentration of 7.6 µg/mL per 10 mg of n-hexane fraction. MCF7 cell viability was lower than that of T47D cells across all concentrations tested. MCF7 cell viability was below 50% at a concentration of 62.5 µg/mL. In contrast, T47D cell viability remained at 100% even at the highest concentration of 125 µg/mL. The IC50 value of MCF7 cells was 43.5 µg/mL.Conclusion: The cucurbitacin content in the n-Hexane fraction was 7.6 µg/mL per 10mg fraction. At this concentration, it moderately inhibits the proliferation of MCF7 cells.Keywords: gama melon parfum, cucurbitacin, HPLC, T47D, MCF7
