Water toxicity to living organisms is of great concern as today’s potable water levels are rapidly decreasing. Decreasing the concentrations of heavy metals in water through biosorption was explored. Saccharomyces cerevisiae was used as a biosorption agent to remediate different heavy metal ions in simulated heavy-metal polluted ground water. Briefly, 20 mL of aqueous solutions with critical concentrations of heavy metal ions namely 0.025 ppm Ni(NO3)2, 1.3 ppm Cu(NO3)2 and 0.5 ppm FeCl3 were added with 5 mL of S. cerevisiae solutions in PDB (McFarland Standard 10) at different concentrations (1 mL, 2 mL, and 3 ml S. cerevisiae in 4 mL, 3 mL and 2 mL distilled H2O, respectively). All treatments were conducted under constant conditions such as temperature and agitation period. After a week, results showed that S. cerevisiae had a significant remediating capability for Ni (II), Cu (II), and Fe (III). The average percentage of removal are as follows: 41.89%, 74.51%, and 29.30% for Ni (II), Cu (II), and Fe (III) ions, respectively. It is found that S. cerevisiae is highly effective in reducing the concentrations of the said metal ions based on the Analysis of Variance at 0.05 alpha.

The study was conducted to evaluate the antimicrobial effect of the Acid Solubilized Collagen (ASC) of Oreochromis niloticus (Nile Tilapia) scales against Staphylococcus aureus. Air dried tilapia fish scales were extracted for collagen initially with 0.1 M of NaOH to remove the base soluble substances then with 10% (v/v) butyl alcohol to remove the fat tissues finally with 0.5 M acetic acid to acquire the solubilized collagen with a yield of 22.40%. Antimicrobial assay was then carried out through Agar diffusion.

The antimicrobial effect was based on the zone of inhibition measured in mm and the result were analyzed and compared using One-Way ANOVA of the Statistical Packages for Social Science 16 (SPSS) at a 0.05 level of significance. The mean zone of inhibition of the Acid Solubilized Collagen (ASC) falls in the 13mm-19mm range. This indicates that Nile tilapia scale collagen is active against S. aureus. Also, the positive control exceeding having the mean zone of inhibition of 39.97mm which exceeds 19 mm is very active against S. aureus. The positive control is significantly more active than the Nile tilapia collagen. The blank setup and negative control, water and acetic acid respectively, had no activity at all. These results prove that Nile tilapia scales are potential source of collagen and Acid Solubilized Collagen (ASC) of Nile tilapia scale is a potential antimicrobial agent.

Pleurotus ostreatus, commonly known as Oyster Mushroom, contains nutrients that are essential in increasing blood platelet count. This study aims to determine the effect of varying concentrations of Pleurotus ostreatus on the blood platelet count of Mus musculus. The Pleurotus ostreatus extract was administered to the mice through intraperitoneal administration then blood samples were collected in different time interventions. Statistics showed significant effect on the blood platelet count of Mus musculus per treatment using paired-samples t-test and no significant effect (at p<0.05) using one-way ANOVA, thus, this study concludes that Pleurotus ostreatus possesses no anti–thrombocytopenic potential.

The research entitled “Development of a Semi-Social Networking Site for the S.C.A.L.E. Program of the Philippine Science High School – Cagayan Valley Campus” dealt with the integration of technology to the documentations and the S.C.A.L.E. achievements of the student included in the program. The program extends the services from the processing the research document to the presentation of the achievement. The program was built and developed through the adaptation of the System Development Cycle. It was proven to provide efficient service to the clienteles of the S.C.A.L.E program.
