Assessing the severity of diatom deformities using geometric morphometry

, 2017
Le pourcentage de déformations des diatomées est de plus en plus utilisé comme un indicateur de stress toxique dans les cours d'eau. Cependant, ce pourcentage ne permet pas de quantifier directement l'importance de ce stress, et certains auteurs suggèrent que la quantification de la « sévérité » des déformations pourrait améliorer les relations de ...

Investigating the influence of climate and volcanic surface aging on fluvial erosion: A case study of Réunion Island, Indian Ocean

Earth Surface Processes and Landforms, Volume 51, Issue 4, April 2026.
Réunion Island is marked by gradients in both precipitation and surface age. Analyzing correlations between metrics related to precipitation, age, and drainage basin morphology, we demonstrate how volcanic surface age impacts the effects of average precipitation and precipitation variability on fluvial erosion.

Shape and Size Variations of Distal Phalanges in Cattle

Animals
Studies on the structure of the distal phalanx help explain the development of laminitis. Additionally, examining the structure of the distal phalanx from a taxonomic perspective also contributes to veterinary anatomy.

Revealing The True Mechanical Behavior Of Porous Tendon Scaffolds Via In Situ Morphometry

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Strain‐dependent morphology is measured in electrospun porous polymeric tendon/ligament scaffolds. This dependence significantly affects the scaffolds’ mechanical characteristics. Analysis of both morphological and mechanical changes helps to correlate them. More physiological characteristics are obtained by considering morphological changes.

Global Hydroclimatic Controls on Multithread River Dynamics

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.

Imaging and 3D Analysis Based on Two or More Three-Dimensional CBCT Recordings before and after Orthodontic Treatment and Maxillofacial Therapy

Applied Sciences
Cone beam computed tomography (CBCT) has emerged as a crucial radiographic technique for orthodontic diagnosis and treatment planning, particularly for cases requiring the assessment of complex anatomical relationships. In the first part of the study, we

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.

Angiotensin‐(1–7) Alleviates Isoproterenol‐Induced Cardiac Hypertrophy by Suppressing Autophagy and Apoptosis Through the Synergistic Action of Mas Receptor and Angiotensin II Type 2 Receptor

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim The aim of this study is to determine whether Angiotensin‐(1–7) [Ang‐(1–7)] alleviates isoproterenol (ISO)–induced cardiac hypertrophy by suppressing excessive autophagy and apoptosis through coordinated Mas receptor (MasR) and angiotensin II type‐2 receptor (AT2R) signaling, and to elucidate the underlying mechanisms.
