This study focused on the possibility of replacing silica in ceramic production with oyster shells. Powdered oyster shells were used instead of silica in the production of ceramics. The texture, color and durability of the ceramics were compared to those made with silica. Six kilograms of Vigan clay and 2.5 kg of ball clay were mixed and soaked in water overnight. The following day, the mixture was kneaded again and filtered. The mixture was placed over Plaster of Paris for the water to be absorbed.

The solidified mixture was then rolled and compressed to let the air escape from the spaces inside the solidified mixture. After this, the mixture was molded, air dried for four days and fired in a furnace. Three trials were made at different temperatures – 900 degrees Celcius, 950 degrees Celcius and 1000 degrees Celcius. The finished products were compared in terms of texture and color to those made using silica.

This research was conducted to determine the ability of “cacao” (Theobroma cacao) seed nicotinamide component to regulate angiogenesis or process of blood vessel formation in duck embryos. Abnormalities in angiogenesis are linked to the development of diseases such as cardiovascular ailments in case of insufficient blood vessel growth and cancer in case of excessive development. Varying "cacao" seed solutions were introduced into the chorion of duck embryos prior to the period of blood island formation.

The fact that 25% of prescribed pharmaceuticals are derived from plants demonstrates the enduring importance of natural products. Marine organisms may be tapped as new sources of natural substances, which can be developed to combat the new trend of acquired resistance in microbes. Because of its abundance in the Philippine coastlines, Caulerpa racemosa or "lato" was evaluated to check for affordability as substitute to commercially available treatments.
