More than Just Type 1 or Type 2: Radiologically and Anatomically Refined Lunate Classification Correlating Ulnar Carpal Alignment and Hamate-Lunate Osteoarthrosis

Background: Hamate-lunate impingement or osteoarthritis can be a cause of ulnar-sided wrist pain. In the literature, the lunate has commonly been classified according to the configuration of its distal articular surface into type 1 and type 2, as ...

Plasmids specifying ε{lunate}-caprolactam degradation in Pseudomonas strains [PDF]

, 1984
The large plasmid DNAs were found in several strains of Pseudomonas sp. capable of growing on ε{lunate}-caprolactam as a sole source of carbon and nitrogen.

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy

Journal of Anatomy, EarlyView.
Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...

Atlas of cortical sulcal imprints on Pan endocasts

Journal of Anatomy, EarlyView.
This comprehensive atlas documents the frequency, position, and variability of cortical sulcal imprints across 21 extant Pan endocasts, providing the first quantitative baseline for comparative paleoneurology. This atlas serves as a reference for distinguishing ancestral from derived features in hominin brain evolution.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Open perilunate injury with lunate revascularization after complete ligamentous avulsion.

, 2014
Perilunate dislocations are a devastating injury to the carpus that carry a guarded long-term prognosis. Mayfield type 4 perilunate dislocations are rare, high-energy injuries that carry a risk for avascular necrosis (AVN) of the lunate.

Neglected Isolated Lunate Dislocation in a Polytrauma Patient Presenting as Acute Carpal Tunnel Syndrome – A Case Report with Review of Literature

Introduction: Lunate dislocations are uncommon high-energy wrist injuries often missed during initial evaluation in polytrauma settings. Case Report: We present a case of a 40-year-old polytrauma patient who sustained multiple injuries following a road ...

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus

Journal of Anatomy, EarlyView.
Knuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.

Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

Journal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...
