SIMULASI DINAMIKA MOLEKUL FENOMENA ADSORPSI DI-(2-ETILHEKSIL)FTALAT (DEHP) PADA MINERAL MONTMORILONIT

Senyawa di(2-etilheksil) ftalat (DEHP) merupakan salah satu polutan yang ditetapkan oleh European Union (EU) dan World Health Organization (WHO) ke dalam daftar polutan utama dan dianggap paling bermasalah bagi kesehatan manusia yaitu dapat menimbulkan gangguan sistem endokrin, sistem saraf, dan hepatotoksik. DEHP digunakan sebagai plasticizer terutama pada polivinil klorida (PVC) yang hampir 50% mengandung DEHP. Senyawa DEHP tidak terikat secara kovalen dengan produknya sehingga mudah terlepas dari produk dan dapat memasuki lingkungan bebas. Jumlah DEHP di lingkungan bebas perlu dikendalikan dan salah satu metode yang sederhana dan efektif adalah adsorpsi. Pada penelitian ini dilakukan adsorpsi dengan pendekatan molekuler, yaitu simulasi dinamika molekul menggunakan perangkat lunak GROMACS. Penelitian ini bertujuan untuk membandingkan adsorpsi DEHP pada montmorilonit dan montmorilonit termodifikasi BDED atau CTMA yang kemudian disebut sebagai organo-montmorilonit, serta menentukan kondisi optimum sistem adsorpsi DEHP. Berdasarkan hasil simulasi, konsentrasi awal (C0) DEHP 0,044 mol/L menghasilkan adsorpsi maksimum yaitu sebanyak 3 molekul DEHP teradsorpsi (77,5%). Saat C0 DEHP dinaikkan menjadi 0,088 mol/L, tidak ada molekul DEHP yang teradsorpsi pada permukaan MMT. Sementara itu, pada MMT (1 lapis) termodifikasi BDED dengan jumlah molekul BDED 0,24 KTK, persentase adsorpsi mengalami peningkatan menjadi 44%. Hal ini menunjukkan bahwa penambahan surfaktan kationik berhasil meningkatkan persentase adsorpsi DEHP

Perkecambahan Dan Perbanyakan Gaharu Secara in Vitro

Agarwood (Aquilaria malaccensis Lank) is one of the forest wood that are continously exploited. Currently, the Indonesian export of agarwood is decreasing because its population is endangered by excessive logging. Agarwood propagations need technology for reproduction of agarwood seedlings and their fungal inoculum. In vitro technique for germination of recalsitrant seeds and micropropagation are technologies that can be used for propagation of agarwood seedlings. An experiment was done to develop techniques for in vitro germination and micropropagation of agarwood. The in vitro germination was done using two different techniques. Firstly, sterile seeds were germinated on an MS medium + 50 mg/l PVP, 50 mg/l GA, and 1 mg/l BA or kinetin. Secondly, sterile seeds were germinated on basal medium of MS, 1/2 MS medium, MS medium without vitamins, as well as on MS medium without pyridoxine, nicotinic acid and WPM. Shoot initiations and multiplications were done on MS and 1/2 MS media containing 1, 3, or 5 mg/l BA. The explants used were cotyledone nodes, terminal shoots, single node with leaf, and sinle node without leaf. The results showed that the seed germination rate on the different media ranged from 7,14 to 50%. The seed germination rate on the MS medium without vitamis was the highest. The best explants for shoot induction and multiplication was single node with leaf which was cultured on MS + 1 mg/l BA

Interactive media for parental education on managing children chronic condition: a systematic review of the literature

BackgroundAlthough some research has examined the use of games for the education of pediatric patients, the use of technology for parental education seems like an appropriate application as it has been a part of the popular culture for at least 30years. The main objective of this systematic review is to examine the literature for research evaluating the use of interactive media in the education of parents of children with chronic conditions.MethodsWe searched the MEDLINE, PSYCHINFO, CINAHL, Cochrane database of systematic reviews and EMBASE databases from 1986 to 2014 seeking original investigations on the use of interactive media and video games to educate parents of children with chronic conditions. Cohort studies, randomized control trials, and observational studies were included in our search of the literature.Two investigators reviewed abstracts and full texts as necessary. The quality of the studies was assessed using the GRADE guidelines.Overall trend in the results and the degree of certainty in the results were considered when assessing the body of literature pertaining to our focused questions.ResultsOur initial search identified 4367 papers, but only 12 fulfilled the criterion established for final analysis, with the majority of the studies having flaws that reduced their quality. These papers reported mostly positive results supporting the idea that parent education is possible through interactive media.ConclusionWe found limited evidence of the effectiveness of using serious games and or interactive media to educate parents of children with chronic conditions.Electronic supplementary materialThe online version of this article (doi:10.1186/s12887-015-0517-2) contains supplementary material, which is available to authorized users

Metabolomic profiling of submaximal exercise at a standardised relative intensity in healthy adults

Ten physically active subjects underwent two cycling exercise trials. In the first, aerobic capacity (VO2max) was determined and the second was a 45 min submaximal exercise test. Urine samples were collected separately the day before (day 1) , the day of (day 2), and the day after (day 3) the submaximal exercise test (12 samples per subject). Metabolomic profiling of the samples was carried out using hydrophilic interaction chromatography (HILIC) coupled to an Orbitrap Exactive mass spectrometer. Data were extracted, database searched and then subjected to principle components (PCA) and orthogonal partial least squares (OPLSDA) modelling. The best results were obtained from pre-treating the data by normalising the metabolites to their mean output on days 1 and 2 of the trial. This allowed PCA to separate the day 2 first void samples (D2S1) from the day 2 post-exercise samples (D2S3) PCA also separated the equivalent samples obtained on day 1 (D1S1 and D1S3). OPLSDA modelling separated both the D2S1 and D2S3 samples and D1S1 and D1S3 samples. The metabolites affected by the exercise samples included a range of purine metabolites and several acyl carnitines. Some metabolites were subject to diurnal variation these included bile acids and several amino acids, the variation of these metabolites was similar on day 1 and day 2 despite the exercise intervention on day 2. Using OPLS modelling it proved possible to identify a single abundant urinary metabolite provisionally identified as oxo-aminohexanoic acid (OHA) as being strongly correlated with VO2max when the levels in the D2S3 samples were considered

Peningkatan Toleransi Alumunium Pada Jeruk Batang Bawah Dengan Teknik Seleksi in Vitro Berulang

Aluminum Tolerance Improvement of Rootstock Citrusthrough Repeated In Vitro Selection. Mia Kosmiatin,Rosa Yunita, and Ali Husni. National orange productivitywas trend to decrease because of pathogen attack andreducing of planting area. One of alternative ways topreserve and increase orange productivity was usingmarginal soil mainly acid soil. This matter pushed thebreeder to prepare tolerant rootstock and stable in the acidsoil. In vitro culture technique was effective and efficientmethods to produce tolerant and stable rootstock in acid soilthrough simulation of acid soil with addition of highaluminum and low pH in the medium. By the simulation theselection could be done in cell level, so cell was selectedafter induction of variation. A rootstock which highcompatibility with scion, useful rooting, and aluminumtolerance could be increased orange productivity throughacid soil development. The research was conducted in 3phase: (1) induction of embryogenic calli, (2) improvementof genetic variation through mutation, and (3) In vitroselection with AlCl3.6H2O for aluminum and low pH tolerant.Immature embryos of rootstock were use as explant. Theresult showed that the best embryogenic calli were inducedon MS basal medium with MW vitamin + NAA 7,5 mg/l +kinetin 0,5 mg/l. Before selection, 1.000 rad dosage was themost tolerant dosage to growth embryogenic calli. Afterselection, 2.000 rad dosage was the best dosage to produceshoots which stable tolerant to aluminum. Selected 88mutant shoots were produced after three times selection onthe same medium which AlCl3.6H2O added at low pH
