Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

open access: yesIntegrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Impact of Chelators on FAC Following Interaction With NaOCl: A Focused Evidence Synthesis Based on a Systematic Search

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This systematic review following PRISMA guidelines evaluated the effects of endodontic chelators on free available chlorine (FAC) in sodium hypochlorite (NaOCl), with emphasis on the influence of concentration, contact time, temperature, and pH. Risk of bias was assessed using the Quality Assessment Tool for In Vitro Studies (QUIN).

Tongue and Glottis Morphology of Cathartes aura and the Secret of Its Functional Adaptation

open access: yesActa Zoologica, EarlyView.
ABSTRACT Cathartes aura, commonly known as the Turkey vulture, is a scavenger bird belonging to the family Cathartidae that is widely distributed throughout the Americas and classified as a New World vulture. Its diet primarily consists of small‐sized carcasses, predominantly of wild animals.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Chromatin Remodeller BRD9 Orchestrates Odontoblastic Differentiation via Coordinating RUNX2‐KLF4

open access: yesCell Proliferation, EarlyView.
During odontoblast lineage commitment, the chromatin remodeller BRD9 acts as a critical epigenetic coordinator, orchestrating the chromatin landscape to facilitate synergistic binding of key transcription factors RUNX2 and KLF4 to target loci for odontogenesis.

Olfactory Tuft Cells Are Critical to Basal Inflammation, Innate Immune Response to Viral Infection, and Modulation of Quiescent Stem Cell Activation, Proliferation and Differentiation

open access: yesCell Proliferation, EarlyView.
Olfactory tuft cells communicate with other mucosal cells in maintaining olfactory epithelial immunity and sensory function. Disruption of tuft cell signalling pathways causes a skewed immune response, leading to heightened inflammation and increased activation of the quiescent stem cells, which are further exacerbated by viral infection.

Preliminary study : microwave decalcification of animal bone tissue

open access: yes, 2014
A análise histopatológica de tecido ósseo exige uma etapa de descalcificação. O método usual consiste na imersão das amostras em ácidos, mas para além de provocarem danos tecidulares, o processo é prolongado.

Alterations of bone proteins in medication‐related osteonecrosis of the jaw

open access: yesEuropean Journal of Oral Sciences, Volume 133, Issue 2, April 2025.
Abstract Changes in the protein expression pattern of osteoblastic lineage cells from the alveolar bone (OLAB) during medication‐related osteonecrosis of the jaw (MRONJ) have rarely been investigated. This lack of information is partly because of the limited availability of healthy samples and the lack of human alveolar bone cell lines for research ...
