Segmentation of 3D images of granular materials obtained by microtomography is not an easy task. Because of the conditions of acquisition and the nature of the media, the available images are not exploitable without a reliable method of extraction of the grains. The high connectivity in the medium, the disparity of the object's shape and the presence of image imperfections make classical segmentation methods (using image gradient and watershed constrained by markers) extremely difficult to perform efficiently. In this paper, we propose a non-parametric method using the stochastic watershed, allowing to estimate a 3D probability map of contours. Procedures allowing to extract final segmentation from this function are then presented.

Comparative evaluation of allograft particulate bone and cortical bone blocks combined with xenograft bone for labial bone defects in the aesthetic zone: a prospective cohort study.
BMC Oral Health
January 2025
State Key Laboratory of Oral Diseases & National Clinical Research Center for Oral Diseases & Department of Implant Dentistry, West China Hospital of Stomatology, Sichuan University, Chengdu, 610041, China.
Purpose: This study aimed to evaluate the osteogenic performance of allograft particulate bone and cortical bone blocks combined with xenograft under bovine pericardium membranes, for treating different degrees of labial bone defects in the aesthetic zone.
Materials And Methods: Twenty-four patients with bone defects were divided into two groups based on defect severity (Terheyden 1/4 and 2/4 groups). The Terheyden 1/4 group received granular bone grafts alone, while the Terheyden 2/4 group received cortical bone blocks combined with granular bone grafts.
In Vivo Confocal Microscopy Findings in Corneal Stromal Dystrophies.

Department of Ophthalmology, Faculty of Medicine, Selcuk University, Konya 42130, Türkiye.
In this study, we aim to evaluate in vivo confocal microscopy (IVCM) findings of corneal stromal dystrophies (CSDs) including granular, macular and lattice corneal dystrophy that can be used for differential diagnosis and monitoring recurrences after surgical interventions. : Patients diagnosed with CSD who were followed-up in the cornea and ocular surface unit were included in this study. IVCM was performed using the Heidelberg Retina Tomograph 3, Rostock Cornea Module (Heidelberg Engineering, Germany) and anterior segment optical coherence tomography (AS-OCT) imaging was performed using the Spectralis OCT (Heidelberg Engineering, Germany).

The objective of this study was to understand the microstructure, textural properties, and in-vitro starch digestibility of instant fried noodle enriched with cross-linked phosphorylated type 4 resistant wheat starch (CLWRS4). Pasting viscosity results showed that CLWRS4 granule had low swelling and high resistance to rupture during high-temperature steaming and frying. Scanning electron microscopic images showed that instant fried noodles prepared using wheat flours containing 20% and 40% CLWRS4 exhibited denser structure and lower porosity than their respective counterparts.

Background: Reports of autoimmune diseases coexisting with autoimmune pulmonary alveolar proteinosis (autoimmune PAP; APAP) are extremely rare. APAP coexisting with autoimmune diseases may often be misdiagnosed as connective tissue disease-associated interstitial lung disease (ILD). Here, we describe a rare case of a patient with systemic sclerosis who was diagnosed with APAP after the exacerbation of lung opacities during treatment with immunosuppressive agents.
