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).

Bacterial Multiresistance and Microbial Diversity of Milk Received by a University Hospital Milk Bank.

Breastfeeding is fundamental for the development and protection of the newborn, and microorganisms present in breast milk are associated with the development of the infant's intestinal microbiota. However, there are factors that interfere with breastfeeding, resulting in the need to supply donated milk to milk banks for these children. Even though there is a restriction on medications prescribed for pregnant and breastfeeding women, some antimicrobials are accepted, as long as they are used correctly and as they can increase the selection pressure for resistant bacteria.

Cytogenomics of (Hymenoptera: Apidae) and the Sharing of a Satellite DNA Family in Several Neotropical Meliponini Genera.

Background/objectives: A striking feature of the karyotypes of stingless bees is the large amount of heterochromatin present in most species. Cytogenomic studies performed in some Meliponini species have suggested that evolutionary events related to the diversification and amplification of satellite DNA families in the heterochromatin may reflect the structuring of phylogenetic clades in this tribe. In this study, we performed a genomic analysis in to characterize different satDNA families in its genome.

Emerging diseases in poultry: The role of Apolonia tigipioensis Torres and Braga, 1938 (Trombidiformes: Leeuwenhoekiidae) in avian parasitism, including the first record of parasitism in the greater rhea, Rhea americana (L., 1758) (Struthioniformes: Rheidae).

The larval chigger mite Apolonia tigipioensis Torres and Braga is an obligatory hypodermic parasite found in South America. Its parasitism can significantly affect the host's health, leading to nodular lesions that consequently result in the host's death. This species has been identified in Venezuela and northeastern Brazil (Pernambuco State), primarily infesting birds, but it can affect mammals, including humans.

Safety of two-dose schedule of COVID-19 adsorbed inactivated vaccine (CoronaVac; Sinovac/Butantan) and heterologous additional doses of mRNA BNT162b2 (Pfizer/BioNTech) in immunocompromised and immunocompetent individuals.

Immunocompromised individuals were considered high-risk for severe disease due to SARS COV-2 infection. This study aimed to describe the safety of two doses of COVID-19 adsorbed inactivated vaccine (CoronaVac; Sinovac/Butantan), followed by additional doses of mRNA BNT162b2 (Pfizer/BioNTech) in immunocompromised (IC) adults, compared to immunocompetent/healthy (H) individuals. This phase 4, multicenter, open label study included solid organ transplant and hematopoietic stem cell transplant recipients, cancer patients and people with inborn errors of immunity with defects in antibody production, rheumatic, end-stage chronic kidney or liver disease, who were enrolled in the IC group.
