Dental Restorative Viability of Zinc Oxide Nanoparticle-Reinforced Zirconia and Baghdadite Ceramic Composites.

J Biomed Mater Res B Appl Biomater

March 2025

Department of Mining, Metallurgical and Materials Engineering, College of Engineering, University of the Philippines Diliman, Quezon City, Philippines.

This study explores the enhancement of properties in zirconia-based ceramic dental restorative materials through the incorporation of baghdadite (CaZrSiO) and zinc oxide (ZnO) nanoparticles. Baghdadite was synthesized via a solid-state sintering method and integrated into zirconia to form baghdadite/zirconia ceramic composites. These composites were sintered with varying concentrations of baghdadite (0%, 5%, and 10%) to enhance bioactivity and support bone tissue repair, and incorporated with 0.

The impact of political assassinations on turnout: Evidence from Colombia.

Proc Natl Acad Sci U S A

March 2025

Munk School of Global Affairs and Public Policy, University of Toronto, Toronto, ON M5S 1W7.

Although a growing literature has investigated the effects of various types of civil war violence on political behavior, no study has examined the impact of assassinations targeting politicians. This is a critical omission, as violence against local politicians is prevalent across civil war contexts and may be the most consequential form of violence for political participation by affecting both candidate supply and voter demand. Using an original dataset of nearly 2,000 killings of Colombian local politicians between 1980 and 2023, we estimate the impact of this violence on voter turnout.

Factors affecting health-seeking behavior in sports climbers in Metro Manila: a cross-sectional study.

Front Sports Act Living

February 2025

Department of Physical and Rehabilitation Medicine, Ospital ng Makati, Makati, Philippines.

Introduction: In the Philippines, studies on athletes are hard to come by when compared to those done internationally, even more so on newer Olympic sports such as Sports climbing. Furthermore, there is a lack of internationally published research on professional health-seeking behavior for the physical conditions of Filipino athletes. Thus, the objective of the study was to investigate the characteristics of sports climbers in Metro Manila that were associated with better health-seeking behavior.

Effects of vector preferential settling in the dynamics of a plant virus model with latent periods.

Department of Mathematics and Computer Science, University of the Philippines Baguio, Governor Pack Road, Baguio City, Philippines.

Insect vectors transmit many plant viruses of agricultural importance. In most cases, these viruses manipulate their vectors' behavior and movement leading to vector settling and feeding preferences that influence virus spread. The latent period within the insect vector is also crucial in virus transmission during vector feeding, however is assumed to be negligible in previous studies.

The migration of Austronesian-speaking populations through Oceania has intrigued researchers for decades. The Kiribati islands, situated along the boundaries of Micronesia and Polynesia, provide a crucial link in this migration. We analyzed the genome-wide data of the Kiritimati population of Kiribati to uncover their genetic origins and connections with other Oceanian groups.

As society ages, improving the health of the elderly through effective training programs has become a pressing issue. Virtual reality (VR) technology, with its immersive experience, is increasingly being utilized as a vital tool in rehabilitation training for the elderly. To further enhance training outcomes and improve health conditions among the elderly, this work proposes an integrated model that combines the Generative Adversarial Network (GAN), Variational Autoencoder (VAE), and Long Short-Term Memory (LSTM) network.

Background: Current guidelines for the treatment of multidrug-resistant/rifampin-resistant tuberculosis (MDR/RR-TB) are based on clinical trials evaluating fixed duration regimens. However, when a regimen succeeds, it remains unknown whether a shorter duration could yield the same results. Similarly, if a regimen fails, it is unclear whether extending the treatment could improve outcomes.

Aim: Tuberculosis (TB) remains a leading cause of death in low- and middle-income countries, and diabetes is a known risk factor for progression to active TB disease. While the Philippines national strategic plan for TB aims to screen 90 % of TB cases for diabetes, the cost-effectiveness of screening is not well known.

Methods: We constructed a decision tree model to assess the cost-effectiveness of providing diabetes testing for 90% of people with an unknown diabetes status at their TB diagnosis and subsequent routine diabetes care, compared to the scenario of providing TB treatment only.

The application of ultramicroporous materials for CO2 separation is limited by the rarity of materials exhibiting stability and rapid scale-up characteristics. In this study, we propose a rational approach to enhance the structural stability and durability of the pillared layer structure. Through the topotactic replacement of protons with metal ions in the parent 4,4'-bipyridine (bpy)-pillared zincophosphate, we observed the formation of edge-sharing dimers of ZnO4N and PO4, as well as the insertion of (VOH2O)2+ into the zinc phosphate layers.

Increasing number of deaf or hard-of-hearing individuals is a crucial problem since communication among and within the deaf population proves to be a challenge. Despite sign languages developing in various countries, there is still lack of formal implementation of programs supporting its needs, especially for the Filipino sign language (FSL). Recently, studies on FSL recognition explored deep networks.

Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis are severe mucocutaneous reactions with high morbidity and mortality, most commonly triggered by prescribed medications. Here, we report a case of a 33-year-old female who developed Stevens-Johnson/Toxic Epidermal Necrolysis after receiving an IV vitamin infusion containing glutathione, vitamin C, and vitamin D. While not commonly associated with the development of Stevens-Johnson Syndrome glutathione has been previously reported to have been the inciting agent in Stevens-Johnson Syndrome cases.
