Hochauflösende Dünnschicht-CT zum präoperativen Staging beim Rektumtumor: Vergleich mit der endo-luminalen Sonographie und der Histologie
1990
Rectal carcinomas are amongst the most common malignant tumours. The aim of this work was to determine whether high resolution CT with thin sections (1 mm) can provide satisfactory delineation of perirectal tumour infiltration. Correct determination of local tumour spread was possible in four out of nine patients and distinction between those tumours confined to the rectal wall and those infiltrating the perirectal tissues was possible in four out of eight patients.
Intravaskuläre Sonographie: Erste klinische Ergebnisse
1991
Intravascular ultrasound is a new diagnostic modality which, for the first time, provides high resolution images of the vessel wall. 91 intraluminal ultrasound studies were performed in 50 patients during the course of 55 diagnostic and therapeutic catheterizations. A F-6 ultrasound catheter (20 MHz) was used. The method is an easily and rapidly performed addition to angiography. Changes in vessel walls (arteriosclerosis, dissection, tumour infiltration) can be readily diagnosed and their extent can be accurately described. The ability to determine luminal cross sectional area is particularly helpful for planning and performing therapeutic interventions.
Prevalence and Risk Factors for Anal Human Papillomavirus Infection in Human Immunodeficiency Virus–Positive Men Who Have Sex with Men
2018
A correction has been published:The Journal of Infectious Diseases, Volume 218, Issue 8, 15 October 2018, Page 1350, https://doi.org/10.1093/infdis/jiy315; International audience; Background:We assessed prevalence and risk factors for anal human papillomavirus (HPV) in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM), who are at high-risk of HPV-related anal cancer.Methods:APACHES is a multicentric, prospective study of anal HPV infection and lesions in HIV-positive MSM aged ≥35 years. At baseline, participants underwent anal swabs for HPV and cytology, plus high-resolution anoscopy. High-risk HPV (HR-HPV) was tested by Cobas4800, with genotyping of HR-HPV positiv…
HIGH-RESOLUTION ULTRASONOGRAPHY (HRUS) OF THE MENISCAL CYST OF THE KNEE : OUR EXPERIENCE
2007
Purpose. This study was undertaken to assess the diagnostic accuracy of high-resolution ultrasonography (HRUS) in the detection of meniscal cysts. Materials and methods. Over a 2-year period, 1,857 patients underwent magnetic resonance imaging (MRI) of the knee for traumatic or degenerative disorders. All patients with MRI evidence of a meniscal cyst were studied by HRUS. HRUS was also performed on an equal number of patients without MRI evidence of meniscal cyst who were used as a control group. All HRUS examinations were conducted by a radiologist blinded to the MRI findings. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of HRUS were assesse…
Mitochondrial function and sirtuin expression in hippocampus of young and old high- and low-capacity runner rats
2016
Introduction: Exercise and aerobic capacity are associated with improved learning in animals and humans. The hippocampus is a brain structure involved in learning and memory. High rates of neurogenesis have been shown to take place in the dental gyrus of hippocampus in response to physical exercise. It is not known whether mitochondrial dysfunction in the hippocampus is responsible for decline in cognitive function associated with low fitness level and aging, and whether intrinsic aerobic capacity is a risk factor for it. Methods: Mitochondrial function was investigated in the hippocampi of young and old highcapacity runner (HCR) and low-capacity runner (LCR) rats using high-performance res…
Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory
2017
We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional informa…
Legal nature of the Supreme Court resolutions
2020
Przedmiotem opracowania jest charakter prawny uchwał Sądu Najwyższego. Charakter ten jest sporny w doktrynie. W tym zakresie występują trzy odmienne stanowiska. Według jednego z nich „uchwały Sądu Najwyższego są orzeczeniami”. Drugie stanowisko przyjmuje, iż „uchwały Sądu Najwyższego stanowią odrębną grupę orzeczeń, nie są jednak orzeczeniami sądu, które dotyczą przedmiotu procesu, ponieważ nie rozstrzygają wprost o jego przedmiocie”. Trzeci kierunek głosi, że „uchwały Sądu Najwyższego, wydawane na podstawie art. 441 § 1 k.p.k., rozstrzygające zagadnienia prawne, nie należą do kategorii orzeczeń”. Przeprowadzone rozważania w niniejszym artykule prowadzą zatem do konkluzji, że uchwały Sądu N…
Modification of a commercial atomic force microscopy for low-noise, high-resolution frequency-modulation imaging in liquid environment.
2011
A key issue for high-resolution frequency-modulation atomic force microscopy imaging in liquids is minimizing the frequency noise, which requires a detailed analysis of the corresponding noise contributions. In this paper, we present a detailed description for modifying a commercial atomic force microscope (Bruker MultiMode V with Nanoscope V controller), aiming at atomic-resolution frequency-modulation imaging in ambient and in liquid environment. Care was taken to maintain the AFMs original stability and ease of operation. The new system builds upon an optimized light source, a new photodiode and an entirely new amplifier. Moreover, we introduce a home-built liquid cell and sample holder …
Il risarcimento sostituivo tra adempimento in natura e risoluzione del contratto
2019
The essay deals with the problem of the so called damages in lieu of the performance and its relations with the specific performance and the resolution. The author attempts to demonstrate that the issue of the damages in lieu of the performance is central to the debate on the priority of the specific performance and on the extent of compensation for damages from resolution.
Justicia digital para el consumidor.
2020
En este libro nos adentraremos en un tópico que se encuentra en pleno desarrollo, tanto en la doctrina como en las legislaciones procesales comparadas. Hemos definido esta obra como una de carácter marcadamente monográfica, la idea es encontrar los elementos centrales del sistema ODR en la literatura más reputada y reciente, y verificar a través de una análisis doctrinario legal las posibilidades de las normas chilenas de protección al consumidor que permitan dar vida a un sistema multi door en un contexto ODR en Chile, mirando siempre la legislación comunitaria más relevante en la materia. El derecho de consumo es un sector del derecho privado con un constante cambio y expansión en las leg…
