Angiogenesis of cancer of the cervix. Contrast-enhanced dynamic MRT, histological quantification of capillary density and lymph system infiltration

1998

Purpose: It was the aim of this project to examine (i) the relationships between contrast-enhanced dynamic MR imaging derived characteristics and histologic microvessel density counts – a recognized surrogate of tumor angiogenesis – from tumors in patients with primary or recurrent cancer of the uterine cervix, and (ii) to correlate these parameters with lymphatic involvement (i. e. lymphatic channels) to assess tumorbiological aggressiveness in terms of lymphatic spread. Materials and methods: Pharmacokinetic MR imaging parameters (amplitude A, exchange rate constant k 21) were derived from contrast-enhanced dynamic MR imaging in thirty-three patients with biopsy proven cancer of the uteri…

Histological changes in odontogenic parakeratinized keratocysts treated with marsupialization followed by enucleation

2020

Background The purpose of this study was to evaluate whether marsupialization treatment induces changes in the histology of odontogenic keratocyst epithelium and to compare our experience with the literature. Material and Methods A retrospective revision of histological samples was performed. 5 patients with odontogenic keratocyst treated with marsupialization follow by enucleation were selected. Histologic evaluation analyzed the changes in the keratocyst epithelium after marsupialization in terms of type of keratinization, thickness of the epithelium and connective tissue, the presence of acanthosis, the presence and grade of fibrosis, the type and grade of inflammation and the presence a…

HSV hepatitis in the mouse: A light and electron microscopic study with immunohistology and in situ hybridization

1988

In order to characterize better the morphology and immune response in acute necrotizing HSV infection, murine HSV hepatitis was examined. BALB/c mice were inoculated intraperitoneally with 10(6) plaque-forming units (PFU) of HSV-1 (Lenette) and HSV-2 (D316). In both groups half the animals were pretreated with silica particles to block macrophage function. Up to 6 days after infection four mice from each group were sacrificed at daily intervals and the livers were examined by light and electron microscopy, immunohistology, in situ hybridization, combined immunohistology/in situ hybridization and titration of viral PFU. HSV-2 infected mice developed severe necrotizing hepatitis with persiste…

Low volumetric BMD is linked to upper-limb fracture in pubertal girls and persists into adulthood: A seven-year cohort study

2009

Abstract The aetiology of increased incidence of fracture during puberty is unclear. This study aimed to determine whether low volumetric bone mineral density (vBMD) in the distal radius is associated with upper-limb fractures in growing girls, and whether any such vBMD deficit persists into adulthood. Fracture history from birth to 20 years was obtained and verified by medical records in 1034 Finnish girls aged 10–13 years. Bone density and geometry at distal radius, biomarkers and lifestyle/behavioural factors were assessed in a subset of 396 girls with a 7.5-year follow-up. We found that fracture incidence peaked during puberty (relative risk 3.1 at age of 8–14 years compared to outside …

Retrospective Study of Patients Diagnosed With Sweet Syndrome in the Health Area of a Tertiary Hospital in the Autonomous Community of Valencia

2012

Sweet syndrome is the most characteristic of the neutrophilic dermatoses. We performed a retrospective study of patients with Sweet syndrome seen in our department between 2001 and 2009, inclusive; the aims were to define the patient profile and to evaluate the clinical and epidemiological differences between subgroups. There were 24 patients (13 women and 11 men). The age distribution was similar in both sexes and showed 2 peaks, one in the fourth decade and the other in the eighth decade. The etiology was predominantly infectious or inflammatory, followed by the idiopathic form. There were 4 cases of paraneoplastic disease, 2 of which involved solid-organ tumors. One case was associated w…

Quantitative measurements of magnetic stray field dynamics of Permalloy particles in a photoemission electron microscopy

2010

By example of a Permalloy particle (40 × 40 μm(2) size, 30 nm thickness) we demonstrate a procedure to quantitatively investigate the dynamics of magnetic stray fields during ultrafast magnetization reversal. The measurements have been performed in a time-resolving photoemission electron microscope using the X-ray magnetic circular dichroism. In the particle under investigation, we have observed a flux-closure-dominated magnetic ground structure, minimizing the magnetic stray field outside the sample. A fast magnetic field pulse introduced changes in the micromagnetic structure accompanied with an incomplete flux closure. As a result, stray fields arise along the edges of domains, which cau…

Clinical and Prognostic Value of 18F-FDG-PET/CT in the Restaging Process of Recurrent Cutaneous Melanoma

2020

Background: Several studies on 18F-FDG-PET/CT have investigated the prognostic role of this imaging modality in different tumors after treatment. Nevertheless, its role in restaging patients with recurrent CM still needs to be defined. Objective: The aim of this retrospective multicenter study was to evaluate the clinical and prognostic impact of 18F-FDG-PET/CT on the restaging process of cutaneous melanoma (CM) after surgery in patients with suspected distant recurrent disease or suspected metastatic progression disease. Materials and Methods: 74 patients surgically treated for CM underwent 18F-FDG-PET/CT for suspected distant recurrent disease or suspected metastatic progression disease.…

Die Beziehungen der Lipoide zu den perizellul�ren Strukturen der Ganglienzellen bei einigen Wirbellosen im Vergleich zu Wirbeltieren

1953

1. Die ektodermalen, gliosen Hullen der Ganglienzellen von Hirudo, Nephrops, Helix, Anodonta, Octopus und Eledone enthalten Lipoide und Lipoproteide. 2. In den Hullen konnten histotopochemisch Plasmal, Glykolipine und Phospholipine nachgewiesen werden. 3. Die untersuchten Scheiden gehen in die Scheiden des Fortsatzes uber. Sie zeigen Doppelbrechung, in nativem Zustand meist ein negatives Kreuz, das nach Glyzerindurchtrankung positiv wird. Diese metatrope Reaktion (Gothlin) weist auf ein geordnetes Eiweis-Lipoidsystem hin, in welchem die Lipoidmolekeln radiar, die Eiweismolekeln zirkular angeordnet sind. Ein solches polarisationsoptisches Verhalten deutet zugleich auf ungesattigte Phosphatid…
