Due to the emergence of multidrug resistant bacteria, researchers are on search for a new source of antimicrobial agents such as plants. This study reports the antibacterial activities of the leaves and rhizomes of E. philippinensis and E. elatior against Gram-positive (M. luteus, S. aureus and S. marcescens) and Gram-negative bacteria (E. coli and P. aeruginosa, B. cereus). Disc diffusion method was employed in determining the antibacterial activity of the plant ethanolic extracts with concentrations of 3000 ppm and 10000 ppm. Highest antibacterial activity was exhibited by the leaves and rhizomes of the Philippine endemic E. philippinensis (10000 ppm) against M. luteus (12.00 ± 0.56) and P. aeruginosa (11.50 ± 0.45), respectively. Of all extracts, only the leaves E. elatior (10,000 ppm) showed antibacterial activity against S. marcescens which is 6.57 ± 0.49. Less

In this paper, the quantum mechanical dynamics of a particle subjected to a damped coupled harmonic oscillator potential was investigated by solving its quantum propagator using the Hida-Streit formulation—also known as the White-Noise analysis. A coordinate transformation to decouple the system was also performed. After the decoupling process, the authors obtained a separate expression of the Lagrangian for a one-dimensional damped harmonic oscillator. Then, the obtained Lagrangian was cast to the classical action and evaluated their propagator using the white noise path integration. The full form of the propagator was solved by taking the product of the individual propagator, and from that, the wave function, particularly the ground state wave function was extracted by symmetrization and setting the quantum number n¬_1=n_2=0. The result agrees with the propagator of a coupled harmonic oscillator without damping (Pabalay et.al, 2007) as the damping factor ? is turned off. Less

Around 2,000 cases of animal bites are reported every year in animal bite centers in Maramag, Bukidnon. The study aimed to determine the prevalence and risk factors associated with dog bite victims in selected barangays of Maramag, Bukidnon, Philippines. A face-to-face interview was carried out using a pre-tested questionnaire among 402 residents in Maramag, Bukidnon, to determine the prevalence and risk factors of dog bite victims of the municipality. Ten barangays were grouped into the rural and urban type of community. The results showed that the apparent prevalence of dog bite victims among residents of Maramag, Bukidnon was 23.6% (95/402). The urban barangays had a prevalence of 26.2% compared to rural barangays with 21%. The gender of victims, civil status, educational attainment, and dogownership are the risk factors that are statistically significant in dog bites. The study revealed that dog bite victims of Maramag, Bukidnon are prevalent with 23.6%, and this result does not depend on the type of community. Furthermore, the study shows that being male, single, have low educational attainment, and dog-ownership increases the risks of being bitten by dogs. Less

Synthesis of zinc oxide nanoparticles on their antimicrobial activity utilizing banana peelings could be a potential candidate to develop nano-formulated natural products as an alternative, efficient, inexpensive, and environmentally safe method with specified properties. The study aimed to investigate the biological synthesis, characterization, and antimicrobial study of zinc oxide nanoparticles (ZnONps) against clinical pathogens Pseudomonas aeruginosa and Staphylococcus aureus using Musa acuminata × balbisiana peelings. Data revealed that varying concentration, temperature, and pH level can significantly influence the antimicrobial activity and plays crucial steps in the preparation of ZnONps. Research on nanoparticles as antibacterial agents can have an essential application in the food industry as antibacterial agents in food packaging and towards foodborne pathogens. Since this study deals with the preliminary investigation on banana peelings locally grown in the Philippines as capping and reducing agent through green chemistry, it can promote potential application in the Philippine food industry. By proper incorporation of nanoparticles into packaging materials it may inhibit or cause foodborne pathogens bacterial death. Less

Cogon grass, a weed occasionally used as livestock feed has a limited nutritive value. Improving the utilization of low quality roughages could be by treatment with nitrogen sources, chemical and physical treatment .Thus an experiment was conducted to assess the voluntary intake and digestibility in vivo of cogon silage and urea-treated corn stover as affected by varying ratios of concentrate: Ipil-Ipil leaf meal (ILM) supplementation in goats. The experiment was setup in a Randomized Complete Block Design (RCBD) with four (4) blocks based on sex-period combination with a 2x3 factorial treatment design: factor A with two types of base forage (cogon silage, urea-treated corn stover), and factor B with three (3) ratios of concentrate: ILM as supplement (1.25:0; 0.75:0.50 and 0.50: 0.75 %BW, DM basis). Results revealed a comparable voluntary intake and in vivo digestibility of cogon grass silage and urea-treated corn stover across three types of supplements, and among supplements across types of basal diet. Interaction between kind of basal diet and type of supplement was not significant. It is, therefore advantageous to mix ILM with concentrate at 0.75%:0.50% BW or 0.50:0.75% BW ratio, DM basis, as supplement to either cogon silage or urea treated corn stover rather than given an all-concentrate supplement at 1.25% BW, DM basis, to save on feed cost.
