Mechanical Thrombectomy Versus Medical Management for Large Ischemic Core Stroke Identified before Inter‐Hospital Transfer: A Post Hoc Analysis of the LASTE Trial

Annals of Neurology, EarlyView.
Objective This study assessed the efficacy of thrombectomy in acute ischemic stroke because of large‐vessel occlusion (AIS‐LVO) initially admitted to primary stroke centers (PSC) and subsequently transferred to a comprehensive stroke center (CSC), with a large ischemic core identified before transfer.

Centrum Semiovale Perivascular Spaces Predict First Hemorrhagic Lesion in Asymptomatic Amyloid‐Positive Individuals

Annals of Neurology, EarlyView.
Objective Identification of cerebral amyloid angiopathy (CAA) before its hemorrhagic manifestations remains limited. We aimed to determine whether severe enlarged perivascular spaces in the centrum semiovale (EPVS‐CSO) identify a prehemorrhagic stage of sporadic CAA by predicting the first appearance of CAA‐related hemorrhagic lesions or incident ...

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Descriptive, stratigraphic, and morpho‐functional study of the myocardium and myocardial bridges in domestic pig hearts

The Anatomical Record, EarlyView.
Abstract The heart is the central organ of the cardiovascular system. The myocardium is composed of a three‐dimensional network of fibers arranged in clockwise and counterclockwise helices, which are essential for proper cardiac contraction. This study aimed to describe the stratigraphic and morpho‐functional pattern of the porcine myocardium to ...

Morphological variation of the conus arteriosus in Chondrichthyes: Implications for ecology and evolution

The Anatomical Record, EarlyView.
Abstract Cartilaginous fish have diverse morphological traits that are essential for understanding their evolutionary history and ecological adaptations. However, the conus arteriosus and its valves, key components of the heart and blood circulation, have been underexplored in phylogenetic and ecomorphological contexts.

Anatomical and histological characterization of the heart of the scarlet ibis (Eudocimus ruber)

The Anatomical Record, EarlyView.
The graphical abstract illustrates the scarlet ibis (Eudocimus ruber) and two views of its heart (ventral and dorsal), highlighting its external morphology. The study also employed complementary approaches, including morphometric analysis, radiography, histological examination, and scanning electron microscopy, to provide a comprehensive ...

Initial treatment strategies and outcomes across haemodynamic thresholds and risk stratification in incident systemic sclerosis–associated pulmonary arterial hypertension: a EUSTAR analysis

Arthritis &Rheumatology, Accepted Article.
Objective Real‐world initial treatment strategies in SSc‐PAH remain incompletely described. We aimed to characterise these strategies across haemodynamic thresholds and risk strata and evaluate outcome associations. Methods We analysed treatment‐naïve SSc‐PAH patients in EUSTAR (2000–2021) fulfilling the 2022 haemodynamic definition.

SEM investigation of the avian atrium wall

, 2004
Dilger, Ryan N./0000-0003-2538-2845In this study, the atrium wall of the chicken was investigated by Scanning Electron Microscopy (SEM) and routine histology. The wall of the left atrium was thicker and more uniform than that of the right atrium. However,

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.
