Analysis of glass-based artworks is important for authentication purposes. In recent years, there have been rapid advancements and improvements in the characterization of glass objects using different analytical approaches. The present study presents an interdisciplinary and multi-analytical authentication approach that provides useful tools and markers to unmask possible imitations, counterfeiting, and forgeries in Cultural Heritage glass beads by comparing the composition of historical and modern glass beads.

- - The study investigates proteolytic enzymes extracted from brewer's spent grain (BSG) sourced from various artisanal beers, assessing their ability to serve as eco-friendly coagulants in cheese-making.
- - Through optimization experiments, the researchers identified that caseinolytic activity peaked at pH 8.0, with significant variations in enzyme efficacy across different BSG samples.
- - Results suggest that certain BSG extracts possess milk-clotting activity comparable to traditional plant-based coagulants, indicating a promising sustainable connection between the brewing and dairy sectors.

Antimicrobial resistance (AMR) is positioning as one of the most relevant threats to global public health and threatens the effective treatment of an ever-growing number of bacterial infections in various healthcare settings, particularly in acute care and surgical units, as well as in the community. Among multidrug-resistant (MDR) gram-negative bacteria (MDRGNB), , and require special attention, since they account for most of the mortality associated with bacterial infections and are often MDR. It is clear that there is an important global variation in antibiotic resistance profiles among MDRGNB species.

- Sacrococcygeal teratomas (SCT) are the most frequent tumors found outside the gonads in young children, but there's limited data on their clinical features and outcomes in the Philippines, as the existing studies have mostly come from other countries.* -
- This study was retrospective and collected data over four years from medical records, focusing on demographics, delivery methods, clinical presentations, tumor classifications, and surgical outcomes, including mortality, morbidity, and recurrence rates.* -
- Out of 29 patients analyzed, most were female, and many presented with a sacral or gluteal mass, but only a small percentage received an accurate prenatal ultrasound diagnosis; imaging methods were used to further evaluate the tumors, with
This study focused on evaluating the influence of geometric dimensions on the drug release kinetics of 3D-printed tablets. An ink based on Gelucire 50/13 was prepared to print ivermectin-loaded tablets. The ink was characterized physicochemically and tablet dissolution tests were carried out.
