Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...

The Therapeutic Potential of Farm Dust Extracts in a Mouse Model of Eosinophilic Inflammation

open access: yesAllergy, EarlyView.
Farm dust extract (FDE) treatment reduces airway eosinophilia, mucus overproduction, and MHC‐II expression on DCs, limiting antigen presentation and Th2 inflammation. It increases PD‐L1 on DCs, promoting T cell deactivation. Additionally, FDE enhances Tregs and upregulates CTLA‐4, reinforcing suppression.

Tau‐targeting active immunotherapy slows progression and reduces pathology in mouse models of tauopathy

open access: yesBrain Pathology, EarlyView.
The efficacy of the novel anti‐tau active immunotherapy, p5555kb, was tested using two mouse models of tau pathology. p5555kb inoculation increased the survival rate and reduced tau pathology in tau‐overexpressing P301L mice and decreased tau seeding in the brains of C57BL/6 mice injected with human‐purified Alzheimer's disease tau.

New Hydrophilic Helixone Dialyzers as an Alternative for Hemodialysis Patients With Membrane Hypersensitivity Reactions: A Retrospective Single‐Cohort Study

open access: yesHemodialysis International, EarlyView.
ABSTRACT Background Synthetic dialysis membranes, particularly those composed of polysulfone blended with polyvinylpyrrolidone, are commonly used in hemodialysis due to their efficiency. However, hypersensitivity reactions—often atypical and not fitting traditional type A and B classifications—have increasingly been reported.

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

open access: yesJournal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...

Polyethersulfone Polymer for Biomedical Applications and Biotechnology

open access: yesInternational Journal of Molecular Sciences
Polymers stand out as promising materials extensively employed in biomedicine and biotechnology. Their versatile applications owe much to the field of tissue engineering, which seamlessly integrates materials engineering with medical science. In medicine, biomaterials serve as prototypes for organ development and as implants or scaffolds to facilitate ...

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Amazonian drought of 2023: Environmental conditions relevant to fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract This paper provides a platform for the following studies within this Special Issue. ‘Ecophysiology of fishes in the two great tributaries of the Amazon in the Anthropocene’. It documents the water quality conditions and accompanying zooplankton community structure and biomass relative to fish health in the Rio Negro and Rio Solimões during the
