Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

open access: yesVIEW, EarlyView.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

Aniridia‐associated keratopathy: Clinical and molecular mechanisms of disease progression and emerging therapeutic targets

open access: yesActa Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare genetic disorder primarily caused by pathogenic variants of the PAX6 gene. It leads to various panocular anomalies, including aniridia‐associated keratopathy (AAK). This review highlights recent insights into its pathogenesis, focusing on clinical staging, microstructural changes in the cornea and molecular ...

An Archaeometallurgical Investigation on Some Archaeological Metal Finds From the Sasanian Site of Jahāngir, Western Iran

open access: yesArchaeometry, EarlyView.
ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and

Enhancing antitumour response to proteasome inhibitors with inhibitors of insulin‐degrading enzyme, a new molecular vulnerability in multiple myeloma

open access: yesBritish Journal of Pharmacology, EarlyView.
Inhibitors of insulin‐degrading enzyme boost PI cytotoxicity through an increased sensitivity of proteasome to PI inhibitors, induction of ISR, DNA damage and Myc down‐regulation. They overcome PI resistance in vitro and induce tumour regression in vivo.

A Common Reference Material for Mass‐Dependent Sn Isotope Compositions: An Inter‐Laboratory Calibration Approach

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points We recommend using the notation δ122/118SnNIST SRM 3161a for mass‐dependent Sn isotope data. We derived conversion factors relative to NIST SRM 3161a for Puri Sn CEZA (0.132 ± 0.011‰), Sn Lyon (0.229 ± 0.016‰), Sn IPGP (0.162 ± 0.018‰). Tin isotope compositions are presented for SPEX CertiPrep Sn and nine USGS reference materials.

Influence of Airborne‐Particle Abrasion and Thermal Cycling on Enamel Bond Strength and Roughness of Lithium Disilicate Treated With a Self‐Etching Ceramic Primer

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study investigated the effect of a self‐etching ceramic primer (Monobond Etch & Prime [MEP]), with or without aluminum oxide airborne‐particle abrasion, on the surface roughness, and microtensile bond strength (μTBS) of lithium disilicate bonded to enamel, compared with the conventional hydrofluoric acid plus silane (HF

Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...
