Electron microscopy using antiglucagon or antiglicentin antisera and the protein A-gold (pAg) technique revealed a population of immunoreactive cells in the gastric mucosa of human fetuses. The secretory granules of these cells showed the same ultrastructural characteristics and the same labeling pattern as pancreatic alpha-granules. These data demonstrate that the stomach of human fetuses cont...
The authors report the successful surgical and chemotherapeutic management of a malignant fibrous histiocytoma with localization in the heart. This rare malignancy has specific morphologic characteristics and is diagnosed in adults when it is already locally aggressive or metastasized. The average survival time for patients with malignant fibrous histiocytoma is < 12 months. Neither clinical no...

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...
The instability and mobility of sand dunes is a major concern of planning and management in arid coastal plains. The aim of this study is to identify morphogenetic characteristics of sand masses and their locations, as well as to identify the processes that formed and transported them in the western part of the Makran coastal plain. Research data and tools were including spatial distributions o...
PURPOSE To examine the feasibility of using sterilized, freeze-dried amniotic membrane (FD-AM) as a substrate for cultivating autologous corneal epithelial cells for ocular surface reconstruction. METHODS Human AM deprived of amniotic epithelial cells by incubation with EDTA was freeze dried, vacuum packed, and sterilized with gamma-irradiation. The resultant FD-AM was characterized for its p...
BACKGROUND Several morphologic distinctions between elderly and young patients with hypertrophic cardiomyopathy (HCM) have been reported. In particular, a crescent-shaped left ventricular (LV) cavity with reversed septal curvature, which is often seen in young patients, is rare in elderly patients. However, those studies were carried out before gene testing became available and heterogeneous ca...
A morphologic and morphosyntactic analyzer for the Italian language has been implemented in VM/Prolog 131 at the IBM Romc Scientific Center as part of a project on text understanding. Aim of this project is the development of a prototype which analyzes short narrative texts (press agency news) and gives a formal representation of their "meaning" as a set of first order logic expressions. Questi...
Background: the use of anthroposcopy in the assessment of posture and morphology of the stomatognathic system of mouth breathing children. Aim: to describe the postural and morphologic characteristics of the stomatognathic system of mouth breathing children, according to age. Method: participants were 100 children, of both genders, with ages ranging from 7 to 11 years and 11 months, leukoderms,...
