Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]

open access: yes, 2014
The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

Morphological variability of Bembidion varium (Coleoptera, Carabidae) in gradient of soil salinity

open access: yesFolia Oecologica, 2020
This article discusses the effect of soil salinity on the variability of Bembidion (Notaphus) varium (Oliver, 1795). The authors of the article collected imagoes of this species in five ecosystems that differed in soil salinity; 13 linear characteristics,

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.

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.
