Abstract

Paneer is a food product that is obtained by heating milk followed by acid coagulation. It is known asa diet food that is recommended for diabetic and coronary heart disease patients. A relatively shortershelf life of paneer is considered to be a major hurdle in its production. The present preliminary studywas conducted to determine antibacterial activity of Lactobacillus plantarum against Eschericia coliand Bacillus cereus, to develop it as biopreservative agent in paneer before using it for dietary food ofdiabetic and coronary heart disease patients in next clinical study. The antibacterial activities were testedthrough Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC)using microdilution well method. Biopreservative activity in paneer was tested using total plate countmethod based on time and temperature variations. Result showed that Lactobacillus plantarum inhibitedBacillus cereus and Eschericia coli with MIC of 3125 and 1562.5 μg/mL whereas MBC was in a value of>6250 and >3125 μg/mL, respectively. As a biopreservative agent, addition of Lactobacillus plantarumto paneer showed no bacterial growth until 7 days in room temperature and 9th day in cold temperature. Itis concluded that Lactobacillus plantarum could be used as a natural biopreservative agent for extendingthe shelf life of paneer. The paneer with addition of Lactobacillus plantarum as biopreservative will thenbe consumed by diabetic patient and coronary heart patients in next clinical study.

Abstract

Docosahexaenoic acid (DHA) is one of essential fatty acids that are beneficial to health. Nowadays, the source of docosahexaenoic acid (DHA) is mainly obtained from fish which are extracted into fish oil products. However, the fish oil products still have some drawbacks in term of purity, acceptable flavor for costumers, and also their not environmental friendly production process. As an alternative solution, heterotrophic microalgae can be used as a potential source for DHA due to their excellence compared to fish oil products. The aim of this study is to isolate the heterotropic microalgae that can produce DHA. The heterotrophic microalgae were isolated from mangrove fallen leaves (Rhizophora apiculata) by using direct planting method. The morphology of pure microalgae colony were observed through light microscope and subsequently fermented for 14 days. Fatty acids were extracted and methylated through direct transesterification method. Identification and quantification of DHA were conducted by using gas chromatography. The results were four isolates of heterotropic microalgae, namely MTKC1, MTKC2, MTKC3, and MTKC4. The extract of MTKC2 that only showed the content of DHA with value of 9.2 % w/w. Therefore MTKC2 is a potential source for DHA. The MTKC2 was further identified by using molecular biology method and confirmed as Thraustochytrium aureum.

Abstract

Adjustment of telomere length by telomerase is considered as a biological marker which determine the proliferation of cancer cells. The telomerase activity in cancer cells is potential to be targeted for cancer therapies. The aim of this study was QSAR studies to determine the descriptors that affect the anticancer activity of 8-substituted-7-methoxy-2H-chromen-2-one derivatives. The descriptors were calculated by using software MOE® 2009.10. to design new derivative compounds that have anticancer potency, to predict pharmacokinetic properties by using preADMET, and to predict tocixity by ADMET predictorTM and interaction predict to telomerase by using Autodock 4.2.6  The results showed QSAR equation was log IC50 = -1.358 (± 1.149) - 2.957 (± 1.019) × AM1_LUMO + 0.041 (± 0.011) × E_vdw + 2.367 (± 0.748) × glob + 0.487 (± 0.100) × log S. Fourteen of the new derivative compounds were designed based on QSAR equation revealed higher activity prediction than the lead compound and performed good absorption in the intestine. Compound (33) is predicted to have low permeability in Caco-2 cells and weakly bound to plasma proteins. Compound (50) predicted weakly bound to plasma proteins as well. Toxicity prediction showed that 9 derivatives compounds were predicted to have lower nearly equal toxicity to the toxicity of the lead compound. The study of the interaction of compounds with the receptor showed that derivatives (2), (4), (40) and (41) have the highest affinity to the receptor TERT with the binding free energy is −9.60 kcal / mol, −9.39 kcal / mol, −9.20 kcal / mol and -9.08 kcal / mol. Based on QSAR study, pharmacokinetic profile, toxicity, and the study of the interaction, four compounds have the potential to be develop as anticancer with telomerase inhibition.

Abstract

Poisoning is an event of human exposure to poisonous substances that are harmful to the body at certain doses. Lead is a heavy metal that can cause toxicity, including neurotoxic effects, hypertension, digestive system disorders, bone and tooth growth disorders, immune system disorders, infertility, and fetal disorders. Fish is a source of nutrients that are often consumed by people, however can also accumulate lead. This study aimed to analyze the lead level in fish and identify the community knowledge level regarding lead contamination in fish. Identification of community knowledge levels regarding lead. Identification of community knowledge levels regarding lead contamination in fish was conducted on three hundred respondents consisting of School of Pharmacy (SF) Institut Teknologi Bandung (ITB) one hundred students, one hundred community, and one hundred housewives. This study also analyzed lead levels in six fish samples using Graphite Furnace Atomic Absorption Spectroscopy (GFAAS). As the result, SF ITB students had the highest level of knowledge in the definition of lead (97%), lead poisoning (98%), fish lead accumulation (75%), the poisoning effects of lead, and sources of lead. However, all of the respondents had a low level of knowledge regarding regulations about lead levels in fish. The lead levels analysis on fish showed that three out of six samples had lead levels that exceeded the limit of lead contamination (>0.2 g/kg). The study indicated that respondents’ knowledge regarding lead contamination in fish is still low and lead-contaminated fish is still being sold on the market.

Abstract

A selective separation techniques with Molecularly Imprinted Polymer (MIP) for High-Performance Liquid Chromatography (HPLC) has been developed for the assay of Dimethylamylamine (DMAA) doping compounds. Molecular imprinted polymer (MIP) is a technique to produce a polymer having the cavity due to the disposal of the templates, in which the cavity serves to recognize the molecules of the same size, structure, chemical and physical properties. The selectivity and affinity of the templates itself will increase, while the concentration value is increasing. MIP is made by DMAA as template, acrylamide as functional monomer, ethylene glycol dimethacrylate (EGDMA) as cross linking, azobisisobutyronitrile (AIBN) as the initiator and chloroform as a porogen solvent; using bulk method. The aim of research are conduct the MIP for the DMAA compound analysis, then the formed MIP is characterized by using Fourier Transform Infra Red (FTIR) and Scanning Electron Microscopy (SEM) to find out the polymer complexes formed and the morphological form of the MIP. The MIP formed then was analyzed by using High-Performance Liquid Chromatography (HPLC) to know the amount of the DMAA, the adsorption capacity, and the adsorption condition found in the MIP. The result of analysis on the content of DMAA in the MIP by using UV-Vis Spectrophotometer is 1.957 mg. Scanning Electron Microscopy (SEM) shows that the MIP has irregular and rough morphological structure; while the NIP has irregular morphology structures and smooth surfaces shape

Abstract

Zebrafish serve as a pivotal model for bioimaging and toxicity assessments; however, the toxicity of banana peel-derived carbon dots in zebrafish has not been previously reported. The aim of this study was to assess the toxicity of carbon dots derived from banana peel in zebrafish, focusing on two types prepared through hydrothermal and pyrolysis methods. Banana peels were synthesized using hydrothermal and pyrolysis techniques and then compared for characteristics, bioimaging ability, and toxicity in zebrafish as an animal model. Pyrolysis-derived banana peel and hydrothermal-derived banana peel showed blue emission under ultraviolet light, indicating excitation-dependent behavior. To test their potential application for bioimaging, a soaking method was used using zebrafish that showed fluorescence intensity in the eyes, abdomen, and tail of zebrafish. Toxicity comparison showed that pyrolysis-derived banana peel had lower toxicity with 50% lethal concentrations (LC50) of 1707.3 ppm than hydrothermal-derived banana peel (LC50 993 ppm) in zebrafish. Both types of carbon dots showed significant differences (p<0.05) in hatching rates at 96 and 120 hours of exposure. Of the two methods for carbon dot synthesis from banana peel, the pyrolysis method had a higher toxicity threshold than the hydrothermal method, as indicated by the LC50 value and the number of zebrafish embryos that died, hatched delayed, and experienced malformation during their development.
