Assessing the impact of TiO nanomaterials on intestinal cells: new evidence for epithelial translocation and potential pro-inflammatory effects.

Understanding the potential impact of nanomaterials (NMs) on human health requires further investigation into the organ-specific nano-bio interplay at the cellular and molecular levels. We showed increased chromosomal damage in intestinal cells exposed to some of in vitro digested Titanium dioxide (TiO) NMs. The present study aimed to explore possible mechanisms linked to the uptake, epithelial barrier integrity, cellular trafficking, as well as activation of pro-inflammatory pathways, after exposure to three TiO-NMs (NM-102, NM-103, and NM-105).

Primary schools' readiness for SARS-CoV-2 preventive measures in Maputo City, Mozambique: a cross-sectional study.

Background: To reduce the spread and transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), schools implemented a series of non-pharmacological interventions such as handwashing stations and cleaning protocols. A baseline assessment of the available interventions and readiness scores for SARS-CoV-2 prevention was conducted in primary schools in Maputo City, Mozambique.

Methods: A cross-sectional study was conducted between August and October 2023.

Chitosan Nanoparticles for Enhanced Immune Response and Delivery of Multi-Epitope Vaccines in a BALB/c Mouse Model.

: is the leading cause of chronic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosal-associated lymphoma. Due to the emerging problems with antibiotic treatment against in clinical practice, vaccination has gained more interest. Oral immunization is considered a promising approach for preventing initial colonization of this bacterium in the gastrointestinal tract, establishing a first line of defense at gastric mucosal surfaces.

The Effect of Peri-Implant Therapy on the Expression of Th17-Related Cytokines in Patients with Peri-Implant Mucositis and Peri-Implantitis: A Prospective Longitudinal Study.

: Cytokines related to the Th17 response have been associated with peri-implant diseases; however, the effect of peri-implant therapy on their modulation remains underexplored. To evaluate the effect of peri-implant therapy on the expression of cytokines related to the Th17 response in the peri-implant crevicular fluid (PICF) (GM-CSF, IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12 (p70), IL-17A, IL-21, IL-23, and TNF-α) of partially edentulous patients with peri-implant disease (PID). : Thirty-seven systemically healthy individuals presenting with peri-implant mucositis (PIM) (n = 20) or peri-implantitis (PI) (n = 17) were treated and evaluated at baseline (T0) and three months after therapy (T1).

The Wildcat That Lives in Me: A Review on Free-Roaming Cats () in Brazil, Focusing on Research Priorities, Management, and Their Impacts on Cat Welfare.

Domestic cats () currently occupy the 38th place in the Global Invasive Species Database. Free-roaming cats potentially have broad-ranging impacts on wildlife, occupying most terrestrial environments globally as house pets, strays, or feral animals. In Australia, for example, cats are responsible for the decline in many vertebrate populations and extinction of several native mammals.
