OBJECTIVES Typical streak artifacts known as metal artifacts occur in the presence of strongly attenuating materials in computed tomography (CT). Recently, vendors have started offering metal artifact reduction (MAR) techniques. In addition, a MAR technique called the metal deletion technique (MDT) is freely available and able to reduce metal artifacts using reconstructed images. Although a com...
AIMS In Escherichia coli, increased expression of efflux pumps and/or decreased expression of porins can confer multiple antibiotic resistance (MAR), causing resistance to at least three unrelated classes of antibiotics, detergents and dyes. It was hypothesized that in Campylobacter jejuni, the efflux systems CmeABC, CmeDEF and the major outer membrane porin protein, MOMP (encoded by porA) coul...
In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity and biodiversity capable of supporting commercial fisheries. We investigated the origin of this apparent biological enhancement over a segment of the North Mid-Atlantic Ridge (MAR) using sonar, corers, trawls, traps, and a remotely operated vehicle ...
In this paper we present a markerless augmented reality (MAR) approach based on real-time 3D reconstruction using a low-cost depth camera, the Kinect. We intend to use this MAR approach for 3D medical visualization. In the actual state of developing, our approach is based on the KinectFusion algorithm with some minor adaptations, as long as our goal is not reconstruct scenes but use the reconst...
The 5-upstream region of a winged bean chymotrypsin inhibitor gene (JVCI-3b) was found to have a high affinity for nuclear matrix. The region, named WCI-3b MAR (matrix attachment region), is highly A + T-rich and contains multiple sites interacting with nuclear matrix. A MAR was also found in the corresponding region of the WCI-x gene, another active gene of the WCI family. Several MAR-binding ...
INTRODUCTION Serious thrombembolic events occur in otherwise healthy marathon athletes during competition. We tested the hypothesis that during heavy endurance sports coagulation and platelets are activated depending on the type of endurance sport with respect to its running fraction. MATERIALS AND METHODS 68 healthy athletes participating in marathon (MAR, running 42 km, n = 24), triathlon (...
Karin Andersson (2018): Metal Artifacts in Computed Tomography – impact of reduction methods on image quality and radiotherapy treatment planning. Örebro Studies in Medicine 172. Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) tre...
زمینه و هدف: بار اسیدی رژیم غذایی تعادل اسیدیته بدن را تحت تاثیر قرار می‌دهد که ممکن است با خطر اضافه وزن، چاقی و همچنین با نمایه کیفیت رژیم غذایی (dietary quality index international: DQI-I)، میانگین نسبت کفایت مواد مغذی (mean adequacy ratio: MAR) و دانسیته انرژی رژیم غذایی مرتبط باشد. این مطالعه به منظور تعیین ارتباط بار اسیدی رژیم غذایی با وضعیت وزنی،کیفیت رژیم غذایی (DQI-I)، میانگین نسبت ک...
