Head morphology in three species of tiger beetles (Coleoptera: cicindelidae): a geometric morphometric study

open access: yesThe European Zoological Journal
Tiger beetles are one of the world’s most studied groups of insects. They are similar in body shape and proportions and have a well-sclerotized head with large protruding eyes that make it wider than the pronotum.

An artificial intelligence approach to palaeogeographic studies: a case study of the Late Ordovician brachiopods of Laurentia [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches
According to the earliest hypothesis which was based on qualitative studies of the Late Ordovician brachiopod fauna, the younger and larger species of Hiscobeccus, which was one of the epicontinental brachiopod fauna of North America, evolved from the ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

open access: yesFEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

open access: yesFEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Morphometric analysis of dolines

open access: yesInternational Journal of Speleology, 1992
The doline is the most specific surface form of karst landscapes, which enables one to distinguish them from “normal†erosion landscapes shaped by surface water. From a morphodynamic point of view the doline constitutes an elementary hydrographic unit, comparable to a simple basin, which, with its system of slopes, conveys water to the absorbing ...

Sex‐Stratified Association of Regional Dopamine Transporter Binding With Disease Progression in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the clinical relevance of dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) abnormalities in amyotrophic lateral sclerosis (ALS), with a prespecified focus on sex‐stratified associations with disease progression and short‐term prognosis.
