using the commercial tanning lotion on three human test subjects of different phototypes. All three test subjects were directly exposed to sunlight from 3:00 PM to 4:00 daily for 15 days. The initial testing did not show any allergic reaction or skin irritation for any of the three test subjects. Quantitative results of the comparative testing were obtained by taking twenty random pixels from each digital picture and assessing their value using the CIE L*a*b. The commercial tanning lotion had the most change in color for all of the three subjects, while the celery seed tanning lotion had the darkest color change for all three subjects. The experiment showed that celery seed extract may be used an active ingredient in tanning lotions which may serve as a cheaper and safer alternative to commercial tanning lotions. #23 Pluronic Lecithin Organogel as an Electrophoretic Medium for Gel Electrophoresis Albert John C. Bromeo, Mariel Ann D.G. Lepaña, Lorenz Rhuel P. Ragasa ABSTRACT Gel electrophoresis is a technique used to separate DNA, RNA, or proteins through a gelatinous matrix into which an electric field is applied. This process is used in numerous fields of science, particularly in molecular biology, genetics, and forensics. Although widely needed, the use of gel electrophoresis is very limited, and one of the limiting factors is the gel itself. Lecithin share many properties with agarose, the common electrophoretic gel used nowadays, and organogels, lipids made into gels, show promising results in the field of gel electrophoresis. This study aimed to determine if pluronic lecithin organogel was a feasible alternative for agarose gel in gel electrophoresis. Lecithin was procured from two sources: commercially-available soy lecithin, and extracted egg lecithin. Through a series of gel-forming tests, it was determined that the best method for lecithin gelation was through the aid of a substance called Pluronic F127, hence Pluronic lecithin organogel. Three gels were made: bought soy lecithin organogel, extracted egg lecithin organogel, and agarose gel. The gels were run in vertical capillary tube gel electrophoresis with coloring dyes as the sample being run. The distances moved by the dyes through the organogels was measured and was then statistically compared to the distances moved by that of agarose. The t-tests yielded positive results as it was determined that there was no significant difference between the distances moved by the dyes in agarose gel and in the two organogels, making Pluronic lecithin organogel a viable electrophoretic medium.
#24 Different Concentrations Of Coconut Meal Decoction as a Component of Culture Media for Cultivating Trichoderma harzianum Mark Daniel S. Broñozo, Erick John C. Carlos, Raymond S. Mejia ABSTRACT Coconut meal, also known as sapal, is the coconut meat from which milk and water have been extracted. It contains organic matters like oils, proteins, and sugars. It also contains inorganic nutrients like potassium, magnesium, calcium, and nitrogen. Coconut meal is usually just thrown away since it has no known uses. Trichoderma harzianum is a fungus that degrades the cell walls of pathogenic fungi. It can also speed up decomposition of organic materials. Farmers may utilize Trichoderma harzianum to speed up the decay of organic matter for making their own fertilizers. This in turn will make agricultural products cheaper. The aim of the study was to device a cheap alternative culture medium for cultivating Trichoderma harzianum using coconut meal decoction as a component of agar and to find the best ratio between sucrose and coconut meal decoction. The study was composed of six setups, five setups with different ratios of coconut meal decoction and sucrose while the other setup is the control setup. The control setup is composed of Czapek Agar. Data was gathered by terms of biomass gained. The samples were weighed before and after the experiment. Data was then analyzed. The results showed that coconut meal decoction was more effective than commercial Czapek Agar. #25 Terpene Extract from Pittosporum resiniferum (Hanga) as an Alternative Paint Thinner Christiane Bernice A. Carrillo, Kimberly Vielle J. Santiago, Hannah Camille D. Velasco ABSTRACT Petroleum nut is abundantly present in areas whose elevation ranges from 600–2,400 m. These include Benguet, Mountain Province, etc. It can also be found in the Bicol Provinces, Palawan, Mindoro, Nueva Ecija, and Laguna Provinces. Turpentine can be extracted from various coniferous trees. In the plant Pittosporum resiniferum or hanga, it comprises up to 50% of its essential oil.
