Metabolic reprogramming has been described as a hallmark of transformed cancer cells. In this study, we examined the role of the glutamine (Gln) utilization pathway in acute myeloid leukemia (AML) cell lines and primary AML samples. Our results indicate that a subset of AML cell lines is sensitive to Gln deprivation. Glutaminase (GLS) is a mitochondrial enzyme that catalyzes the conversion of G...
BACKGROUND The purpose of this study was to evaluate whether performing an assessment of myocardial deformation using speckle tracking imaging during the recovery period after dobutamine stress echocardiography (DSE) allows detection of significant coronary artery disease (CAD) in patients with chest discomfort. METHODS DSE and coronary angiography were performed in 44 patients with chest dis...
OBJECTIVE The aim of this study was to apply speckle tracking imaging (STI) to evaluate rabbit sepsis induced myocardial injury. MATERIALS AND METHODS Rabbits were injected with the endotoxin lipopolysaccharide (LPS). before and 2h, 4h, 6h, 8h, 12h after the injection of LPS, conventional echocardiography and STI were performed to measure left ventricular end diastolic diameter (LVDd), end-sy...
The ideal edges of bilayer graphene (BLG) are that the edges of the top and bottom graphene layers (GLs) of BLG are well-aligned. Actually, the alignment distance between the edges of the top and bottom GLs of a real BLG can be as large as the submicrometer scale or as small as zero, which cannot be distinguished using an optical microscope. Here, we present a detailed Raman study on BLG at its...
BACKGROUND Newer 2D strain software has a potential to assess layer-specific strain. However, normal reference values for layer-specific strain have not been established. We aimed to establish the normal ranges of layer-specific longitudinal and circumferential strain (endocardial global longitudinal strain (GLS), transmural GLS, epicardial GLS, endocardial global circumferential strain (GCS), ...
In this paper, an accurate Image Registration method is presented. It combines a feature-based method, which allows to recover large motion magnitudes between images, with a Generalized Least-Squares (GLS) motion estimation technique which is able to estimate motion parameters in an accurate manner. The feature-based method gives an initial estimation of the motion parameters, which will be ref...
Ganoderma lucidum spores (GLS) constitute a healthy food for humans, but the hard spore shells are difficult to digest. In this study, digestive properties of GLS in different forms (sporoderm-unbroken, sporoderm-broken [SB-GLS] and sporoderm-removed [SR-GLS]) were investigated vitro digestion fermentation. After simulated digestion, morphologies all three changed slightly. gastric intestinal a...
The fact that cancer cells rewire their metabolism to meet their extreme energetic and biosynthetic needs has long been known, since the seminal studies by Otto Warburg demonstrated that cancer cells heavily rely on glycolysis even in the presence of oxygen, the so-called Warburg effect. However, efforts to therapeutically target the special requirements of cancer cells have only gained tractio...
I develop a novel diagnostic procedure to estimate the associations between measurement errors of expected returns proxies and rm characteristics. Application to GLS, a popular implementation of the implied cost of capital ("ICC"), yields the rst direct empirical evidence that ICC measurement errors i) are persistent, ii) can be associated with rmsrisk or growth characteristics, and therefo...
Clinical guidelines (GLs) play an important role in medical practice, and computerized support to GLs is now one of the most central areas of research in Artificial Intelligence in medicine. In recent years, many groups have developed different computer-assisted management systems of GL. Each approach has its own peculiarities and thus a comparison is necessary. Many possible aspects can be ana...
