Morphologic variation in the P1 element of Mississippian species of the conodont genus Pseudognathodus

2018

A revision of the Austin Conodont Collection at the Natural History Museum, London, has revealed a diverse assemblage of P1 elements of Pseudognathodus . Pseudognathodus homopunctatus, Ps. lineatus, Ps. mermaidus and Ps. symmutatus are di?erentiated and a new species, Ps. posadachaconae , is de?ned from material from North Wales. The systematic of these species is updated. A revised diagnosis is provided for the genus Pseudognathodus , as well as for the species Ps. lineatus and Ps. symmutatus . The types of Ps. symmutatus cannot be differentiated from immature specimens of Ps. homopunctatus . The evolutionary relationships of Pseudognathodus species are discussed. Stratigraphic distributio…

Computer-Aided Diagnosis System with Backpropagation Artificial Neural Network—Improving Human Readers Performance

2016

This article presents the results of a study into possibility of artificial neural networks (ANNs) to classify cancer changes in mammographic images. Today’s Computer-Aided Detection (CAD) systems cannot detect 100 % of pathological changes. One of the properties of an ANN is generalized information —it can identify not only learned data but also data that is similar to training set. The combination of CAD and ANN could give better result and help radiologists to take the right decision.

Cryobiopsy as a New Tool for Complications Diagnosis During Follow-up After Lung Transplantation: Single Institution Case Series

2020

ABSTRACT Background The first description of performing a new diagnostic procedure, cryobiopsy, in lung transplant recipients in Poland. Methods Three cases of patients after lung transplantation were analyzed in context of the procedure of cryobiopsy, which was performed in a hybrid room with a bronchoscopic video track and C-arm radiograph. Patients were subjected to complete anesthesia and intubated. Two or three sections with an average diameter of 5 mm were collected. Results The sections were large and fully diagnostic. In all 3 described cases they brought a decisive element into diagnosis. Conclusions Cryobiopsy is a useful tool in the differential diagnosis of lesions and complicat…

Complex regional pain syndrome - phenotypic characteristics and potential biomarkers

2018

Complex regional pain syndrome (CRPS) is a pain condition that usually affects a single limb, often following an injury. The underlying pathophysiology seems to be complex and probably varies between patients. Clinical diagnosis is based on internationally agreed-upon criteria, which consider the reported symptoms, presence of signs and exclusion of alternative causes. Research into CRPS biomarkers to support patient stratification and improve diagnostic certainty is an important scientific focus, and recent progress in this area provides an opportunity for an up-to-date topical review of measurable disease-predictive, diagnostic and prognostic parameters. Clinical and biochemical attribute…

Twenty-year trends in the prevalence of Down syndrome and other trisomies in Europe : impact of maternal age and prenatal screening

2013

This study examines trends and geographical differences in total and live birth prevalence of trisomies 21, 18 and 13 with regard to increasing maternal age and prenatal diagnosis in Europe. Twenty-one population-based EUROCAT registries covering 6.1 million births between 1990 and 2009 participated. Trisomy cases included live births, fetal deaths from 20 weeks gestational age and terminations of pregnancy for fetal anomaly. We present correction to 20 weeks gestational age (ie, correcting early terminations for the probability of fetal survival to 20 weeks) to allow for artefactual screening-related differences in total prevalence. Poisson regression was used. The proportion of births in …

MMP-10/stromelysin-2 promotes invasion of head and neck cancer.

2011

BackgroundPeriostin, IFN-induced transmembrane protein 1 (IFITM1) and Wingless-type MMTV integration site family, member 5B (Wnt-5b) were previously identified as the invasion promoted genes of head and neck squamous cell carcinoma (HNSCC) by comparing the gene expression profiles between parent and a highly invasive clone. We have previously reported that Periostin and IFITM1 promoted the invasion of HNSCC cells. Here we demonstrated that Wnt-5b overexpression promoted the invasion of HNSCC cells. Moreover, stromelysin-2 (matrix metalloproteinase-10; MMP-10) was identified as a common up-regulated gene among Periostin, IFITM1 and Wnt-5b overexpressing HNSCC cells by using microarray data s…

New Insights into the Anterior Complex

2020

<b><i>Objective:</i></b> To introduce visualization of the germinal matrix (GM), external angle of the frontal horn, and periventricular white matter while evaluating the anterior complex (AC) during basic ultrasound assessment of the fetal brain. <b><i>Case Presentations:</i></b> This is a retrospective observational study of healthy women with singleton pregnancies, with no increased risk of fetal central nervous system anomalies, attending routine ultrasound screening at 20–32 weeks’ gestation. Seventeen cases are presented in which an abnormal aspect of the GM or external angle of the frontal horn or periventricular white matter on AC eval…

Uncommon evolutions and complications of common benign liver lesions

2018

International audience; Frequently encountered on abdominal imaging studies, the majority of common benign liver lesions are asymptomatic, confidently diagnosed by imaging, and do not require further workup, follow-up, or treatment. The increasing use of multimodality liver imaging, has allowed the recognition of uncommon evolutions of common benign liver lesions such as size changes, fibrotic regression, and content and vascularization changes, and their complications such as rupture, hemorrhage, thrombosis, extrinsic compression, and malignancy. The purpose of this pictorial review is to describe and illustrate the incidence and diagnostic features of these uncommon evolutions and complic…

Histological features and ki-67 index in cervical atypical lesions

2008

One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are really HPV-associated. We studied 52 AL cases to evaluate whether the morphological features and the proliferation index, assessed by Mib1 (Ki67) immunostaining, would be useful to better understand the real nature of AL, with relation to the HPV presence and to the proliferati…
