Clinical characteristics, management, and malignancy rate of oral lichen planus: a European multicenter study.

Introduction: Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous condition that includes a spectrum of oral clinical manifestations ranging from mild painless white lesions to painful erosions and ulcers. The purpose of this European multicenter study is to describe the general characteristics of OLP lesions, the clinical and histopathological diagnosis, and the management of OLP at different European Oral Medicine and Maxillofacial Surgery centers, in order to minimize selections biases and provide information about the current trends in the treatment of OLP across Europe.

Materials And Methods: Data and histopathological records of patients with OLP were retrospectives revised and only those patients that fulfilled the diagnostic criteria from the 2016 position paper by American Academy of Oral and Maxillofacial Pathology were included.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Fracture-related infections of the lower extremity - Analysis of costs and their drivers.

Objectives: Fracture-related infection (FRI) is a feared complication in orthopaedic trauma surgery. They are associated with multiple surgical interventions and prolonged antibiotic treatment duration, and hence, increased costs. The objective of this study was to assess the costs of FRI treatment in a Tertiary Swiss Trauma Center and to identify the variables associated with increased costs.

A2B adenosine receptor-triggered intracellular calcium mobilization: Cell type-dependent involvement of Gi, Gq, Gs proteins and protein kinase C.

Activation of PLCβ enzymes by G and G proteins is a common mechanism to trigger cytosolic Ca increase. We and others reported that G inhibitor FR900358 (FR) can inhibit both and G- and, surprisingly, G-mediated intracellular Ca mobilization. Thus, the G-G-PLCβ-Ca signaling axis depends entirely on the presence of active G, which reasonably explained FR-inhibited G-induced Ca release.
