Alveolar ridge preservation with autogenous tooth graft: A histomorphometric analysis of 36 consecutive procedures.

Background: The aim of this study was to analyze the histomorphometric findings of autogenous tooth grafting (ATG) for alveolar ridge preservation (ARP), using graft material from extracted teeth. Variations by sex, age and location of extracted teeth, as well as any associated complications, were also assessed.

Materials And Methods: This prospective, single-cohort study was conducted using ATG placed in extraction sockets.

Rescue stenting after failed mechanical thrombectomy: The RES-CAT study.

Introduction: The efficacy of intracranial rescue stenting (RS) following failed mechanical thrombectomy (MT) in large-vessel occlusion (LVO) stroke remains uncertain. We aimed to evaluate clinical outcomes of RS in patients with anterior circulation LVO stroke following unsuccessful MT.

Patients And Methods: We conducted a retrospective analysis using the Stroke Code Registry of Catalonia (January 2016-March 2022), a prospective, population-based registry including patients treated at 10 comprehensive stroke centers.

Pattern detection in the vehicular activity of bus rapid transit systems.

In this paper, we explore different methods to detect patterns in the activity of bus rapid transit (BRT) systems focusing on two aspects of transit: infrastructure and the movement of vehicles. To this end, we analyze records of velocity and position of each active vehicle in nine BRT systems located in the Americas. We detect collective patterns that characterize each BRT system obtained from the statistical analysis of velocities in the entire system (global scale) and at specific zones (local scale).

NADPH Oxidase 5 (NOX5) Upregulates MMP-10 Production and Cell Migration in Human Endothelial Cells.

NADPH oxidases (NOXs) have been described as critical players in vascular remodeling, a mechanism modulated by matrix metalloproteinases. In this study, we describe for the first time the upregulation of MMP-10 through the activation of NOX5 in endothelial cells. In a chronic NOX5 overexpression model in human endothelial cells, MMP-10 production was measured at different levels: extracellular secretion, gene expression (mRNA and protein levels), and promoter activity.

Geometrical impacts of platonic particles on nematic liquid crystal dynamics.

Platonic-solid-like particles in liquid crystals offer intriguing opportunities for engineering complex materials with tailored properties. Inspired by platonic solids' geometric simplicity and symmetry, these particles possess well-defined shapes such as cubes, tetrahedra, octahedra, dodecahedra, and icosahedra. When dispersed within nematic liquid-crystalline media, these particles interact with the surrounding medium in intricate ways, influencing the local orientational order of liquid crystal molecules.
