Lactococcal 949 group phages recognize a carbohydrate receptor on the host cell surface
2015
ABSTRACT Lactococcal bacteriophages represent one of the leading causes of dairy fermentation failure and product inconsistencies. A new member of the lactococcal 949 phage group, named WRP3, was isolated from cheese whey from a Sicilian factory in 2011. The genome sequence of this phage was determined, and it constitutes the largest lactococcal phage genome currently known, at 130,008 bp. Detailed bioinformatic analysis of the genomic region encoding the presumed initiator complex and baseplate of WRP3 has aided in the functional assignment of several open reading frames (ORFs), particularly that for the receptor binding protein required for host recognition. Furthermore, we demonstrate th…
The enigmatic young brown dwarf binary FU Tau: accretion and activity
2010
FU Tau belongs to a rare class of young, wide brown dwarf binaries. We have resolved the system in a Chandra X-ray observation and detected only the primary, FU Tau A. Hard X-ray emission, presumably from a corona, is present but, unexpectedly, we detect also a strong and unusually soft component from FU Tau A. Its X-ray properties, so far unique among brown dwarfs, are very similar to those of the T Tauri star TW Hya. The analogy with TW Hya suggests that the dominating soft X-ray component can be explained by emission from accretion shocks. However, the typical free-fall velocities of a brown dwarf are too low for an interpretation of the observed X-ray temperature as post-shock region. O…
Application de la photogrammétrie à la documentation de l’art rupestre, des chantiers de fouilles et du bâti
2017
During his archaeological missions the Museum of Prehistoric Anthropology tested the 3D modelling of several typesof objects. His team chose the ‘Structure-from-Motion’ (SfM) method which works according the basic principle of stereoscopicphotogrammetry, namely that 3D structure can be resolved from two or more overlapping, offset images. Most of other methodscapable of surveying, at high resolution, often complex objects and landforms are very expensive and have a difficult portability.Using only a consumer-grade digital camera and a scale on the ground, the user moves through the environment, acquiringphotographs of the area of interest from as many locations and perspectives as possible.…
Detecting the stimulated decay of axions at radio frequencies
2018
Assuming axion-like particles account for the entirety of the dark matter in the Universe, we study the possibility of detecting their decay into photons at radio frequencies. We discuss different astrophysical targets, such as dwarf spheroidal galaxies, the Galactic Center and halo, and galaxy clusters. The presence of an ambient radiation field leads to a stimulated enhancement of the decay rate; depending on the environment and the mass of the axion, the effect of stimulated emission may amplify the photon flux by serval orders of magnitude. For axion-photon couplings allowed by astrophysical and laboratory constraints(and possibly favored by stellar cooling), we find the signal to be wi…
Factors related to excessive patellofemoral loading in rearfoot running
2015
Running is recognized as one of the most popular exercise methods. Furthermore, running related injuries have been under the scope for the last few decades. Synchronous function between the segments of the lower limbs is necessary for efficient locomotion. Patellofemoral pain syndrome is a common exercise related syndrome and multifactorial in nature. The purpose of this study was to measure contact forces and frontal plane moments to detect the factors that are associated with atypically high patellofemoral joint loading in rearfoot striking (RFS) running pattern, and moreover, which could possibly contribute to development of the patellofemoral pain syndrome. 39 team sport female athletes…
Imaging features of histological subtypes of hepatocellular carcinoma: Implication for LI-RADS
2021
Background & Aims The histopathological subtypes of hepatocellular carcinoma (HCC) are associated with distinct clinical features and prognoses. This study aims to report Liver Imaging Reporting and Data System (LI-RADS)-defined imaging features of different HCC subtypes in a cohort of resected tumours and to assess the influence of HCC subtypes on computed tomography (CT)/magnetic resonance imaging (MRI) LI-RADS categorisation in the subgroup of high-risk patients. Methods This retrospective institutional review board-approved study included patients with resected HCCs and available histopathological classification. Three radiologists independently reviewed preoperative CT and MRI exams. T…
Läromedel i svenskundervisning i waldorfskolor
2015
Tutkielman tarkoituksena oli selvittää mitä oppimateriaaleja ruotsinopettajat käyttävät suomenkielisissä steinerkouluissa ala- ja yläkoulussa ja kuinka steinerpedagogiikka vaikuttaa oppimateriaalien valintaan. Tutkimuksella pyrittiin selvittämään myös miten steinerkouluissa käytössä oleva vihkotyöskentely tapahtuu ja millaisia ajatuksia opettajilla on siitä. Tutkimukseen osallistui 10 steinerkoulun ruotsinopettajaa, jotka vastasivat kyselyyn nettilomakkeella. Kysely alkoi neljällä taustatietoja kartoittavalla kysymyksellä, joita seurasi viisi opettajien käyttämien materiaaleihin liittyvää kysymystä. Kysymykset 7-9 koskivat vihkotyöskentelyä. Kyselyyn vastanneet opettajat käyttivät opetukses…
Real-world experience with obeticholic acid in patients with primary biliary cholangitis
2021
Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…
