Sodium metabisulfite is widely used as a preservative in many food and beverage products, yet its potential effects on cognitive and motor functions at low concentrations remain poorly understood. Evaluating learning, short-term memory, and motor activity is essential, as these functions are critical indicators of neurological health and could be impacted by low-level exposure to sodium metabisulfite. The aim of this study was to investigate the effects of sublethal concentrations of sodium metabisulfite on cognitive and motor functions using (fruit flies) as the model organism.

Chronic exposure to inhalants, like toluene, can have long-lasting effects on behavior. However, most animal studies lack the incorporation of both sexes and do not focus on the abstinence period.

Introduction: Folkloric claims have surrounded essential oils, including their enhancement of learning and memory through inhalational exposure. Few studies in humans have shown a benefit in cognition, albeit incremental. However, this benefit may not be entirely attributable to the essential oil aroma but may be confounded by psychological associations.

To reduce the accumulation of microplastic and nanoplastic pollution, bioplastics made from biodegradable materials are promoted as a more sustainable alternative because it can degrade faster than plastics. However, plastics also leach out chemicals as they degrade and disintegrate, but the potential toxicity of these chemicals leaching out from plastics and especially bioplastics is poorly explored.

The pleiotropic actions of the Farnesoid X Receptor (FXR) are required for gut health, and reciprocally, reduced intestinal FXR signaling is seen in inflammatory bowel diseases (IBDs). Here, we show that activation of FXR selectively in the intestine is protective in inflammation-driven models of IBD. Prophylactic activation of FXR restored homeostatic levels of pro-inflammatory cytokines, most notably IL17.

Genital mycoplasmas can break the cervical barrier and cause intraamniotic infection and preterm birth. This study developed a six-chamber vagina-cervix-decidua-organ-on-a-chip (VCD-OOC) that recapitulates the female reproductive tract during pregnancy with culture chambers populated by vaginal epithelial cells, cervical epithelial and stromal cells, and decidual cells. Cells cultured in VCD-OOC were characterized by morphology and immunostaining for cell-specific markers.

Exosomes from -infected ECTO cells were characterized using cryo-electron microscopy, nanoparticle tracking analysis, Western blot, and Exoview analysis. The antigenicity of the exosomes from -infected ECTO cells was also tested using THP-1 cells and our newly developed vagina-cervix-decidua organ-on-a-chip (VCD-OOC) having six microchannel-interconnected cell culture chambers containing cells from the vagina, ectocervical, endocervical, transformation zone epithelia, cervical stroma, and decidua.

Schistosomiasis remains to ha/ve a significant public health impact in the Philippines. The Kato-Katz (K-K) technique is the reference standard and most used technique for definitive diagnosis of intestinal schistosomiasis for control programs in endemic regions. However, this has a very low sensitivity when applied in areas of low endemicity and patients with light infection.

The factors contributing to behavioral differences in variants remain elusive despite associations with several Spike protein mutations. Exploring accessory proteins may provide a wider understanding of these differences since these proteins may affect viral processes that occur beyond infection.

Background: Lung, liver, and colorectal cancers are among the leading causes of cancer-related deaths in the Philippines. As chemotherapeutic treatments remain expensive, native plants are being studied as alternative treatments for use in primary care. In this study, Alpinia elegans leaf ethanolic extract ("tagbak," TGK) was screened for potential anti-cancer activity against lung (A549), colorectal (HCT116) and liver (HEPG2) cancer cells.

Along with structural and non-structural proteins, SARS-CoV-2, SARS-CoV, and MERS-CoV can also express accessory proteins. During the past few years, there have been only a few studies focusing on this set of proteins. Despite available data on these proteins, there are still a lot of questions on the functions of these proteins during infection that must be answered.
