Introduction: Despite extensive research on Alzheimer’s Dementia (AD), a proper treatment for this disease is still largely undetermined. Thus, an effective, simple, cheap, and minimally invasive animal model for hippocampal-related AD is highly needed. This study compares the influence of trimethyltin (TMT), scopolamine, and D-galactose-AlCl3 (DgalAl) on the rat’s hippocampus spatial memory,...
This research examines the development of the P5 Worksheet (Projek Penguatan Profil Pelajar Pancasila) at SMAN 1 Terara to shape student character. The results show that the majority of training participants strongly agreed that the material was well-delivered, interesting, and easy to understand. The presenters were also considered capable of fostering creativity among the participants. No...
Peat soil is found abundantly on the surface of the Central Sumatra basin. In fact, for coastal areas, peat dominates at depths of up to several meters. In the dry season, fires are the most frequent natural disasters in peatlands, especially in Riau Province. Several significant problems have developed in the process of extinguishing peatland fires, so that peatland fires are difficult to...
