Abstract Background Some COVID-19 patients with similar quantitative CT measurements had variable clinical presentation and outcome. The absence of reasonable explanations, such as pre-existing comorbidities or vascular complications, adds to the confusion. authors believed that neglecting impact certain severe morphologic features could be an alternative radiological explanation. This study ai...

The present experiment was designed to test whether specific recordable changes in the neuromuscular system could be associated with specific alterations in soft- and hard-tissue morphology in the craniofacial region. The effect of experimentally induced neuromuscular changes on the craniofacial skeleton and dentition of eight rhesus monkeys was studied. The neuromuscular changes were triggered...

Meningiomas are classified into three groups (benign, atypical, and anaplastic) based on morphologic characteristics. Atypical meningiomas, which are WHO grade 2 tumors, and anaplastic meningiomas, which are WHO grade 3 tumors, exhibit an increased risk of recurrence and premature death compared with benign WHO grade 1 tumors. Although atypical and anaplastic meningiomas account for <10% of all...

PURPOSE Results from this and other laboratories strongly suggest that differences in the properties of the ocular media that bathe cells in the anterior and posterior regions of the lens contribute to its normal growth patterns and polarity. The aim of this study was to compare the effects of aqueous and vitreous on the morphology of lens epithelial explants, with particular attention to chang...

PURPOSE The aim of this study was to investigate the expression changes of epithelial mesenchymal transition (EMT)-related molecules induced by TGF-β signaling in a human corneal epithelial cell line (HCECs). METHODS The cellular response to TGF-β was evaluated by immunoblotting, quantitative real-time RT-PCR, and immunofluorescence microscopy in HCECs. RESULTS TGF-β significantly increased...

PURPOSE The present study hypothesized that different bone healing patterns through initial stages of osseointegration would be observed when three distinct commercially available implant systems (Nobel Groovy, Implacil, and Zimmer TSV) were used, leading to significant variations in histometric levels of total bone and new bone formation during the osseointegration process. MATERIALS AND MET...

On wave-influenced river deltas, wave-driven sediment redistribution affects progradation, and therefore avulsions, while avulsions change where is delivered to the coastline, affecting coastline shape. Coastline shape, in turn, rates patterns. Here we use a numerical model investigate how asymmetry of wave climates delta avulsion behaviors, which are coupled with shape evolution. Increasing wa...

Follicular helper T-cell (TFH) lymphomas comprise a unique group of that represent neoplastic proliferations follicular T-cells and share genetic, immunophenotypic, morphologic, clinical features. Angioimmunoblastic lymphoma (AITL) is the prototypical TFH lymphoma; in addition, 2017 revised World Health Organization (WHO) 4th edition recognizes two other subtypes: (FTCL) nodal peripheral with T...

Myxoid changes have been rarely reported both in adrenocortical adenomas and carcinomas. The recent observation by our group of an adrenal myxoid tumor with morphologically borderline features, but aggressive clinical behavior prompted us to review a series of 196 adrenocortical lesions, comprising 122 carcinomas and 74 adenomas, to define the morphologic, phenotypical and clinical characterist...
