Impact of Collagenated and Non-Collagenated Deproteinized Bovine Bone Mineral on Schneiderian Membrane Integrity in Rabbits.

This investigation focused on the influence of collagen on the integrity of the Schneiderian membrane during maxillary sinus augmentation in a rabbit model. The aim of this study was to elucidate the relationship between membrane integrity and bone regeneration in augmented maxillary sinuses using collagenated and non-collagenated grafts, through detailed histological and histomorphometric analyses. In this forward-looking, randomized, split-mouth design, bilateral maxillary sinus augmentation was conducted on 12 rabbits.

When two signals cross paths: cGAS-STING and ER stress in kidney disease progression.

Previous reports have suggested that both the endoplasmic reticulum (ER) stress and cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes pathways contribute to the progression of chronic kidney disease; however, the relationship between these 2 pathways in kidney injury has not been fully elucidated. Andrade-Silva et al. revealed that the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes pathway can enhance ER stress through the protein kinase R-like ER kinase (PERK)-mediated signaling cascade in kidney tubular epithelial cells and sequentially augment fibrosis during kidney injury.

C57BL/6J and C57BL/6N mice show distinct aging-associated behavioral alterations.

Aging affects emotional, cognitive, and social functions, increasing susceptibility to neuropsychiatric conditions. C57BL/6 mice are commonly used to study aging mechanisms, yet differences between C57BL/6J and C57BL/6N substrains remain underexplored. This study compared aging-related behavioral changes in these substrains.

Retrospective evaluation of a novel ultrasound-based imaging analysis software for predicting radiofrequency ablation areas.

Objective: This study aimed to introduce and evaluate a novel software-based system, BioTrace, designed for real-time monitoring of thermal ablation tissue damage during image-guided radiofrequency ablation for hepatocellular carcinoma (HCC).

Methods: BioTrace utilizes a proprietary algorithm to analyze the temporo-spatial behavior of thermal gas bubble activity during ablation, as seen in conventional B-mode ultrasound imaging. Its predictive accuracy was assessed by comparing the ablation zones it predicted with those annotated by radiologists using contrast-enhanced computed tomography (CECT) 24 hours post-treatment, considered the gold standard.
