Morphological, immunohistochemical and molecular analysis of follicular dendritic cell sarcomas: L1CAM as a new diagnostic marker

open access: yesHistopathology, EarlyView.
Pathohistological analysis of FDCS revealed a morphological spectrum and led to the identification of the adhesion molecule L1CAM as a novel diagnostic immunomarker for FDCS. Sequencing identified NFKBIA as the most frequently altered gene, of note, exclusively in cases with a predominant epithelioid cytomorphology.

Clinicopathological Challenge: Five Males Presenting With Progressive Skin Thickening and Hoarse Voices

open access: yesInternational Journal of Dermatology, EarlyView.
ABSTRACT Five male patients, including four siblings and one unrelated child, presented with progressive hoarseness, waxy eyelid papules, mucosal thickening, and skin plaques. Histopathologic analysis revealed PAS‐positive perivascular hyaline deposition, and genetic testing confirmed a homozygous ECM1 mutation in all patients, consistent with lipoid ...

Genomic Signatures of Ancient Vicariance in Host‐Specific Fungal Endophytes Across the Soltis Line in the Pacific Northwest

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Foliar fungal endophytes are a highly diverse component of most plants, both in terms of taxonomic composition and function. Investigating the biogeography of these microbial symbionts in well‐studied regions complements our understanding of the patterns and processes already inferred for animals and plants.

A new species of Characidium (Characiformes: Crenuchidae) from the Iguaçu National Park, Rio Iguaçu basin, Paraná, Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from the Iguaçu National Park, Brazil. The new species can be diagnosed from the congeners by the absence of conspicuous vertical bars, blotches and spots along the sides of the body, the presence of a scaled isthmus and adipose fin, a series of scales below lateral line and the presence of a thin dark

Multiple exostoses and an osteochondroma in a Pliocene canid from Langebaanweg ‘E’ Quarry (South Africa)

open access: yesJournal of Anatomy, EarlyView.
Overview of XS of pathological radius. Using anatomical descriptions, CT scanning and bone histology, we investigate several skeletal overgrowths of bone (exostoses) in the skeleton of a jackal‐like canid from the world famous Langebaanweg, a Mio‐Pliocene locality in South Africa.

Diaphragmatic Ultrasonography in Preterm Newborns With Respiratory Distress Syndrome on Invasive Mechanical Ventilation: An Observational Study

open access: yesJournal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim In preterm newborns, Respiratory Distress Syndrome (RDS) is one of the leading causes of mortality. Treatment often requires invasive mechanical ventilation (IMV), which can cause diaphragmatic dysfunction. Ultrasonography is a promising tool for assessing diaphragmatic function in neonates.

Unprecedented Combination of Rare Degenerative Pathologies in an Octogenarian Ex‐Football Player

open access: yesNeuropathology, EarlyView.
ABSTRACT A 79‐year‐old former professional football player presented with language deficits and cognitive changes. A year later, he had difficulty completing sentences, and 3 years after onset, was reduced to one‐word answers. He developed severe apathy and agitation, and became more impulsive.

An upgraded key for identifying all native species, subspecies and varieties of the genus Carex (Cyperaceae) in Europe and the Caucasus

open access: yesNordic Journal of Botany, EarlyView.
The last pan‐European key to Carex taxa was published in 1980 by Chater. Since that time several new species have been described, and numerous nomenclatural changes, including the recognition that the former genus Kobresia should be incorporated into Carex as C. subg. Euthyceras, have been made. This article provides a comprehensive key to identify all
