SCIENCE EDUCATION INSTITUTE Office of the Director

My warmest greetings to the members of the National Science Consortium and the participants of this 2nd National DOST-SEI ASTHRDP-NSC Scholars’ Conference In its 2nd serving, this conference hopes to spawn a healthier convergence among our much valued graduate scholars as we encourage them to go into research and development (R&D) that shall lead into innovations that would cater to the needs of our industries. The dynamic nature of science gives constant pressure to our industries as to how to adapt to the rapid advancements in technology and the production process. It is therefore critical that we create a sound scientific environment where R&D is at its crest in order to ensure the stable rise of the economy. We are of the firm belief that the participants of this conference, as evidenced by the kind of works presented in this conference are competent enough to influence the creation of such type of scientific environment. This conference is one of the many ways that the Science Education Institute supports to create a critical mass of scientists and engineers that will lead the country in finding S&T-based solutions to the pressing issues of this time. We hope that through this conference, we are able to do that and more. I congratulate all our participants and look forward to seeing you as active members of the science community. Thank you and mabuhay!

NATIONAL SCIENCE CONSORTIUM

February 12, 2013 On behalf of the Steering Committee of the National Science Consortium, I warmly welcome all the faculty, students and guests to the 2nd ASTHRD-NSC Student Research Conference! In 2010, the Science Education Institute convened the 10 top science universities in the country into the National Science Consortium (NSC) to assist it to implement the Accelerated Science & Technology Human Resource Development Program (ASTHRD) to fast-track the PhD and MS science scholarship programs of the country. The institutions which were invited into the NSC accepted this challenge. The NSC is a large and strategic consortium. All combined, the NSC has more than 700 PhD faculty and offers 33 PhD and 51 MS science degree programs. Currently, there are about 500 MS and 100 PhD ASTHRD scholars in the NSC. This is a heavy responsibility, and also a great opportunity to contribute to the development of the country. Beyond the management of the scholars, the NSC has taken the challenge to enhance our science programs in three ways: by improving of the training of our scholars, by promoting innovation in research, and by forming collaborative programs in strategic areas. I am pleased to announce that the DOST has responded positively by providing financial resources so that we can undertake our plans. This conference will feature two important concerns of the NSC: how to build an effective consortium and mentorship. Together, these two concerns are keys to a successful NSC. We are thankful to have with us the best resource speakers on these topics. Rev. Bienvenido F. Nebres, S.J. and Dr. Ester A. Garcia were two of the pillars of the first DOST science consortium; Dr. Lourdes Cruz, Dr. Oscar Zamora, and Dr. Florencia Claveria are exemplars of effective mentors in three areas of science. Their messages are addressed to both the faculty and scholars of the NSC. Of course, the main participants of this conference are the scholars. Unlike the usual conferences, this is an opportunity to share one’s work, test one’s ideas, and, yes, also to practice and improve. Secondly, this conference is also a unique opportunity for the NSC to meet and form shared arrangements, whether it is to teach and develop courses or to undertake collaborative research. It is our hope that this 2nd Student Research Conference, and its future editions, will become one of the foundations for a strong Filipino science community! Sincerely yours,

FABIAN M. DAYRIT, Ph.D. Chair, NSC Steering Council

QUORUM SENSING INHIBITION BY NON-POLAR FRACTIONS FROM HALYMENIA DURVILLAEI BORY DE SAINT-VINCENT FROM BOLINAO, PANGASINAN, PHILIPPINES Dang Marviluz L. Espita1,2 and Marco Nemesio E. Montaño1* 1 The Marine Science Institute, Seaweed Chemistry Laboratories and Pilot Plant Velasquez St., National Science Complex, College of Science, University of the Philippines, Diliman 1101, Quezon City 2 Institute of Chemistry ,National Science Complex, College of Science, University of the Philippines, Diliman 1101, Quezon City Email: [email protected] Various important biological functions including luminescence, antibiotic response, plasmid transfer, motility, virulence, biofilmformation and biofouling have been found to be regulated through the interference of bacterial communication mediated by signal molecules. Theprocess of signal interference, termed as quorum sensing inhibition (QSI), has brought about researches that screen for lead compounds that are able to block bacterial crosstalk. Bioassays involving the use of biosensors like the Chromobacteriumviolaceum have provided high-throughput means of screening for bioactive fractions from several samples. The pigment production of C. violaceum is elicited via a density-dependent cell-to-cell signaling system. The inhibition of pigment production indicates positive QSI. The availability of this method allows the screening of samples even at the field, which is advisable for samples of marine origin. Halymeniadurvillaei is a red marine algae belonging to the Order Cryptonemiales. It is commonly found in rocky substrates with frequent wave action, and is seldomlyinfestated by epiphytes and other biofouling organisms. This observation gives insight into its rich phytochemistry that may play an essential in the prevention ofits surface colonization. In this study, H. durvillaei samples were collected from Bolinao, Pangasinan in Northwestern Luzon, Philippines. Voucher specimens were deposited to the G.T. Velasquez Herbarium at the UP Marine Science Institute for proper identification and authentication. Samples for crude extraction were weighed, frozen, and lyophilized prior to extraction. Freeze-dried samples were homogenized, weighed, and macerated in methanol for 3-5 days. Following solvent extraction, bioassay-guided fractionation manifests quorum sensing inhibitory activities in DCM and hexane-drivedfractions of H. durvillaei. All experiments were done in at least triplicate. Current work is on the purification and characterization of the QSI compounds.

ISOLATION, CHARACTERIZATION, AND MOLECULAR CLONING OF A NOVEL SERINE PROTEASE-LIKE GENE OF THE ELASTASE SUB-CLASS FROM MORINGA OLEIFERA SEED EMBRYOS. Maini, ZA, Panes, VP*, Canlas, MKC, Garcia RN, Tolentino VS. Serine proteases are a wide variety of enzymes that hydrolize peptide bonds in proteins and thus have varied regulatory uses in several members of the plant genera (Antao & Malcata, 2005). In this study, RNA from varying developmental stages of Moringa oleifera were isolated and subjected to reverse transcription polymerase chain reaction (RT-PCR) and Random Amplification of cDNA Ends polymerase chain reaction (RACE-PCR) using designed gene-specific primers. Sequencing results of gel purified amplification products show a 734 and 544 base pair cDNA amplicons with a blastx (putative amino acid homolgy) score of 83% and 88% similarity to the Homo sapiens Neutrophil Elastase gene (GB ACC78413) over 155 and 140 translated amino acid residues respectively, both in the (+2) frame over three of nine different embryological developmental stages. DNA extraction to verify the gene identity of the amplicons is currently in progress, with a 1500 bp amplicon having been produced using the same gene specific primers. Sequencing and subsequent cloning of the PCR products will be perfomed. Preliminary data showing resemblance to the neutrophil elastase gene may show potential involvement in terms of elastin breakdown during seed germination, and may also indicate possible antibacterial and antiviral properties of the embryo.

SYNTHESIS, MORPHOLOGICAL, AND STRUCTURAL CHARACTERIZATION OF MOISTURE ABSORBER PARA-TOLUENE SULFONIC ACID-DOPED POLYANILINE Anelyn P. Bendoy,1 *Mylene M. Uy,1 and *Reynaldo M. Vequizo2 1 Chemistry Department, MSU-Iligan Institute of Technology 2 Physics Department, MSU-Iligan Institute of Technology A greenish black sample of polyaniline which is indicative of its emeraldine salt form was successfully synthesized through oxidative chemical polymerization using aniline monomer, ammonium peroxydisulfate as an oxidant and p-toluene sulfonic acid as acidic medium and dopant. The polymerization process was done inside an inert environment fabricated gloved box to ensure minimum initial interaction of water molecules to the samples.

Structural characterization of polyaniline samples via Fourier Transform-Infrared (FT-IR) Spectroscopy revealed a broad absorption peak at ~1115 cm-1 which is assigned C-H in-plane bending an indication that the sample is in an emeraldine salt form. In addition, it is validated by the calculated values of degree of oxidation (~40%). On the other hand, the sulfonated polyaniline was confirmed by an absorption peak at ~1034 cm-1 characteristic of SO3- group present in the structure. Hence, a site for water molecule accommodation is present which is supported by the hollow centred rod-like structure formation observed in the surface morphology of the sample using Scanning Electron Microscopy (SEM). This is substantiated by the new peaks observed at ~3239 cm-1 in the FT-IR spectra, indicative of intermolecular hydrogen bonding O-H stretch, which were obtained after exposure of sample to moisture. Furthermore, increase in weights of the sample was observed after exposure to moisture. Therefore, pTSA-doped polyaniline is a moisture absorber compound and can be used as a prototype for humidity sensing materials.

ISOLATION OF HIGH MOLECULAR WEIGHT COMMUNITY DNA FROM RUMEN DIGESTA FORMETAGENOMIC STUDIES Stephen G. Sabinay1, Antonio C. Laurena2*, Cesar C. Sevilla3, and Medino Gedeun N. Yebron, Jr.3 1 Physical Sciences Department, West Visayas State University, Iloilo City; 2Biochemistry Laboratory, 2 Institute of Plant Breeding, University of the Philippines Los Baños, Laguna; 3Animal Science Cluster, University of the Philippines Los Baños, Laguna Microorganisms in rumen digesta provide a rich source of genes for biotechnological applications. However, these microbes are difficult to grow in vitro, thus understanding their roles in rumen fermentation remains a challenge. In order to overcome the limitations of culture-based techniques, metagenomic analysis can be applied. In this study an indirect DNA extraction method was developed and evaluated by comparing it against four routinely used method designed for soil, bacteria and plant samples. The modified method facilitates the concentration of microorganims from rumen digesta and employs the use of bead-beating in the presence of high concentrations of sodium dodecyl sulfate (SDS), salt, and EDTA, with subsequent purifcation of ammonium acetate and isopropanol. This method resulted in a 2.2- to 4.4-fold increase in DNA yield when compared to four other widely used method. The community DNA recovered has an estimated maximum size of 9.4- to 23 kb and was pure enough for restriction digestion and PCR amplification making it ideal for metagenomic library construction and microbial diversity studies. In addition, the method developed in this study does not use hazardous substances such as phenol and chloroform nor does it utilize expensive spin columns for purification.

CYCLIC DIARYLHEPTANOID GARUGAMBLIN-I ISOLATED FROM THE BARK OF GARUGA FLORIBUNDA (“BOGO”) Mylene M. Uy* and Putlih Adzra T. Pautong Air-dried bark sample of Garuga floribunda (“Bogo”) was extracted with 95% ethanol and sequentially partitioned with chloroform. The concentrated chloroform extract (GFC) was fractionated employing gravity column chromatography (gcc) using gradient mixtures of hexane-ethyl acetate through ethyl acetate-methanol at 10% increment. The eluates were pooled based on their tlc profiles, resulting to a total of eight fractions which were subjected to brine shrimp lethality test, with GFC4 showing the highest toxicity (LC50=47.8 ppm). Purification of GFC4 afforded five sub-fractions (GFC4.1 to GFC4.5), among which GFC4.1 exhibited the highest toxicity (87.1% mortality) against A. salina. It was then purified, resulting to seven sub-fractions, three of which (GFC4.1.1GFC4.1.3) were sent for NMR spectroscopic analysis. Among the remaining sub-fractions, GFC4.1.5 was further purified through gcc on the bases of relative purity and weight. This in turn afforded six sub-fractions, with GFC4.1.5.2, GFC4.1.5.5, and GFC4.1.5.6 subjected to NMR spectral analyses. On the other hand, formation of crystals in GFC3, indicative of high purity, was the basis for purifying the said fraction. This was done by simply repeatedly washing the crystals with methanol since they were found to be insoluble in it. The filtrate (dark-green in color) was labeled GFC3.1. Total purification was then performed by washing the white crystals with hexane, with the filtrate labeled as GFC3.2. The isolated crystals (GFC3.3) were then submitted for NMR, MS, and X-ray Crystallographic analyses. Out of the eight sub-fractions sent, only GFC3.3 was completely characterized. Based on spectroscopic analyses, the identity of the isolate (crystals) was deduced to be garugamblin-I (C21H22O4).

REMOVAL OF ORGANIC AND INORGANIC POLLUTANTS FROM AQUEOUS SYSTEM BY CHITOSAN MOLECULARLY IMPRINTED POLYMER IN MODIFIED AND UNMODIFIED FORM Xyza Jane Templonuevo and Soma Chakraborty, Ph.D.* Department of Chemistry, School of Science and Engineering, Ateneo de Manila University, Loyola Heights, Quezon City Water availability and the ecological and toxicological effects of both organic and inorganic pollutants render water pollution a major global concern. The target organic pollutant selected for this study is a triacylglyceride (a lipid type) which can be found in wastewater from slaughterhouses and meat processing facilities. When present in significant amount, lipids can deplete the amount of dissolved oxygen available for aquatic organisms causing disruption of the aquatic ecosystem such as loss of aquatic communities by death or migration. An economically attractive mode of water remediation is the use of chitosan, a biopolymer derived from deacetylation of the structural polysaccharide chitin. Chitin is the second most abundant natural polymer and can further be obtained by recycling discarded crustacean shell wastes from canning industries. In this study, molecular imprinting was performed on chitosan to increase its selectivity for the target pollutant. Chitosan was molecularly imprinted by crosslinking with glutaraldehyde in the presence of triolein (a triacylglyceride) as the template. Crosslinking was found to be complete after 2h reaction time at 50°C. To increase the interaction of chitosan with the template, hydrophobic modification was also done by N-acylation using octanoyl chloride. Characterization by FTIR of the molecularly imprinted and acylated chitosan are currently being performed. Template rebinding will also be investigated as a function of initial template concentration and contact time. Furthermore, since numerous studies have shown that chitosan sequesters heavy metal ion pollutants by chelation through its amino groups, the efficiency of the molecularly imprinted chitosan in simultaneous removal of an organic pollutant (triolein) and an inorganic pollutant (a heavy metal ion) in aqueous system will also be studied. FUNCTIONAL ELUCIDATION OF THREE CONTIGS OF MARSUPENAEUS JAPONICUS TO WHITE SPOT SYNDROME VIRUS (WSSV) BY dsRNA INTERFERENCE Maria Violeta Tarea, Mary Beth Maningasa,b*, Aiko Shitarac, Hidehiro Kondoc, Ikuo Hironoc a Graduate School, University of Santo Tomas, España Manila, Philippines, b Department of Biological Science, College of Science, University of Santo Tomas, España, Manila, Philippines, c Laboratory of Genome Science, Tokyo University of Marine Science and Technology, Konan 4-5-7, Minato-ku, Tokyo 108-8477, Japan White spot syndrome virus remains to be the main threat in shrimp farming due to its high mortality rate of up to 100% upon infection in 3 to 7 days. To develop strategies to combat the virus, studies on different genes involved in the host-virus interactions are done to reveal their functions. In this study, contigs 17, 31 and 34 expressed in the genome of kuruma shrimp was silenced using RNA interference to elucidate its role in the shrimp immune system challenged with WSSV. Genomic DNA of the shrimp expressed all three contigs, followed by DNA sequencing. Blast analysis revealed that all three are homologous to the WSSV genome. Mortality data showed that contig 34 provided the highest protection at 25% survival at day 7 p.i. with the samples in the controls groups PBS and GFP all dead on the same sampling date. TAXONOMY AND NEW DISTRIBUTIONS OF INVASIVE SUCKERMOUTH ARMORED CATFISHES (PISCES: Pterygoplichthys) Joel M. Chavez Department of Biology, College of Science, De La Salle University The invasion of suckermouth armoured catfishes (SACs) is one of the more dramatic and traumatic events in Philippine ecology in recent times. The effects of this invasion have rippled through socio-economic dimensions as reported in local media that it has left an imprint in the consciousness of many Filipinos on the ill-effects of a lowly aquarium fish fondly called as “janitor fish.” In this paper, the complications of the mis-identities of the fish are discussed. Discussed as well are the new areas of distribution for SACs and assessments of their invasion threat levels in these areas. IDENTIFICATION OF MANGROVES, SEAGRASSES AND SEAWEEDS OF NOGAS ISLAND, ANINI-Y, ANTIQUE Laureen Morillo-Manalo and Armi May Torrechilia-Guzman* Institute of Marine Fisheries and Oceanography, College of Fisheries and Ocean Sciences, University of the Philippines Visayas Miagao, Iloilo A field survey was conducted in Nogas Island Fish Sanctuary, one of the hundreds of marine protected areas in the Philippines to identify the species of mangroves, seagrasses and seaweeds present in the area. This survey was conducted on July 2012 and participated by UP Visayas Fisheries students. Samples of mangroves were collected from the seaward to landward area while the seagrasses and seaweeds were collected on seagrass beds stretching along the front side of the island.

Samples were packed in plastic bags and brought to the Fish Biology lab of the University of the Philippines VisayasCollege of Fisheries and Ocean Sciences for identification using field guides and identification keys. Eight mangrove species were found such as Avicennia marina, Bruguiera cylindrica, Ceriops tagal, Osbornia octodonta, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa and Sonneratia alba. Five species of seagrasses were also identified which include Cymodocea rotundata, Halodule pinifolia, Halophila ovalis, Syringodium isoetifolium and Thalassia hemprichii while there were seven species of seaweeds such as Enteromorpha sp., Gracilaria sp., Halimeda sp., Padina sp., Sargassum sp. and Turbinaria sp. The number of species found in the mangrove and seagrass beds implies that the island has a diverse and rich habitat which is beneficial for aquatic organisms like fish, molluscs and crustaceans as these areas are considered as spawning and nursery grounds where these organisms can seek refuge. DIVERSITY OF SOME ENDEMIC Nepenthes SPECIES OF THE PHILIPPINES BASED ON MORPHOLOGY, rbcL, matK, AND 18S rDNA SEQUENCES Rachel Y. Acil1, Ma. Genaleen Q. Diaz2*, Victor B. Amoroso3*, Rita P. Laude2*, Merlyn S. Mendioro2*, and Antonio C. Laurena4* 1 Graduate School, University of the Philippines, Los Baños, Laguna, 4031; 2 Genetics and Molecular Biology Division, Institute of Biological Sciences, CAS, UP Los Baños, 4031, Laguna; 3 Department of Biology, Central Mindanao University, Musuan, 8710 Bukidnon; 4 Institute of Plant Breeding, Crop Science Cluster, College of Agriculture, UP Los Baños, 4031, Laguna The form of resemblance using morphological characters were determined using numerical phenetic analysis; and the rbcL, matK, and 18s rDNA genes from the thirteen Philippine endemic Nepenthes species were partially sequenced to determine the extent of diversity of the thirteen endemic Nepenthes species. Numerical phenetic analysis partitioned the thirteen endemic species into seven distinct groupings. Molecular analysis and DNA barcoding was done using three genes: ribulose-1,5biphosphate carboxylase large sub-unit gene (rbcL), maturase-K (matK), and 18s ribosomal DNA, which were amplified and sequenced. The samples were all correctly identified up to genus level based on the three genes using nucleotide BLAST. Genetic distances were computed using Kimura 2-Parameter model and Jukes-Cantor method. The 18s rDNA gene sequences had the highest genetic divergence, followed by matK and rbcL. The phylogenetic tree based on the concatenated rbcL and matK sequences formed distinctive clades of the three individuals for each Nepenthes species. Thus, there is morphological and genetic variation among the thirteen endemic Nepenthes species. This study further proved that the two recommended barcodes, rbcL and matK, are not powerful enough to discriminate the thirteen Nepenthes species. IMMUNOMODULATORY AND CHEMOPREVENTIVE PROPERTIES OF SULFATED POLYSACCHARIDES FROM SARGASSUM SILIQUOSUM J. G. Agardh Ross D. Vasquez1,4, John Donnie A. Ramos 2,3,4 1 Department of Pharmacy, Faculty of Pharmacy 2 Department of Biology, College of Science 3 Research Center for the Natural and Applied Sciences 4 The Graduate School, University of Santo Tomas, España, Manila Sulfated polysaccharides from brown seaweeds attracted extensive interest due to their numerous biological activities and structural diversity. Sulfated polysaccharides isolated from Sargassum siliquosum J. G. Agardh were investigated for their immunomodulatory and chemopreventive potentials using peripheral blood mononuclear cells (PBMC), hepatocarcinoma cells (HepG2), renal carcinoma cells (RCC), colon carcinoma cells (HCT) and promyelocytic leukemic cells (PML) and analyzed using HPLC, Ashing-Acid Digestion Ion Chromatography and FT- IR. Chemical analysis showed that polysaccharides contain fucose (.35 mM) and mannose (37.762 mM) for AQ; fucose (.363 mM) and mannose (37.762 mM) for F1 and mannose (1.69 mM) for A1; with IR spectra comparable to standard alginate and fucoidan with sulfate with peaks at 1450-1350 cm-1, O-H stretch with strong signals between 3400-3200 cm-1, C-H stretch at 3000-2850 cm-1 ; C-O at 1300-1000 cm-1, C=O at around 1630-1695 cm-1; degree of sulfation were 11% (AQ), 3.5% (A1) and .21% (A1). AQ, F1 and A1 significantly induced proliferation of PBMCs and displayed significant antiproliferative activity in both HepG2 and renal carcinoma cells in vitro in dose-dependent manner and cytostatic effect in human colon cancer cells (p 2.5 mg/mL) radical scavenging assay (p
