Scheduling precedence graphs with communication times is the theoretical basis for achieving efficient parallelism in message-passing machines. The lack of global information on the tasks, due to communication, has lead to develop local scheduling heuristics such as the Earliest-Task-First. Using knowledge on computation, communication, and system topology, a class of global priority-based sche...

Cancer cells reprogram metabolism to provide the energy, nucleotides, lipids, amino acids and other building blocks required to proliferate and survive in the stressful tumor microenvironment [1]. Changes in cancer metabolism were first noted in the 1920’s with Otto Warburg’s discovery that tumors show increased aerobic conversion of glucose to lactate (termed the Warburg Effect). A recent revi...

BACKGROUND Different aspects of acute stroke management and strategies for stroke prevention derive from two viewpoints: specific traditional and historical backgrounds and evidence-based medicine from modern randomized controlled trials (RCTs), meta-analysis and authorized clinical practice guidelines (GLs). Regarding stroke, GLs have been published by national and international organizations ...

BACKGROUND In obstructive hypertrophic cardiomyopathy patients with preserved left ventricular (LV) ejection fraction, we sought to determine whether LV global longitudinal strain (LV-GLS) provided incremental prognostic utility. METHODS AND RESULTS We studied 1019 patients with documented hypertrophic cardiomyopathy (mean age, 50±12 years; 63% men) evaluated at our center between 2001 and 20...

The desire to predict who will develop heart failure (HF) has inspired researchers for a long time. Numerous so-called predictive biomarkers have been developed, studied, published, and forgotten. Various suggestions of biomarkers have been deemed to add little to clinical practice.1–3 However, a few have reached current clinical practice, including NT-proBNP, troponins, and creatinine, which c...

Background: BCS class II and IV drugs, which have low solubility, provide a number of challenges for formulation scientists working on oral delivery of drugs. Aims: The aim and purpose of the present work was to design a gel liquisolid tablets for Atorvastatin calcium a water insoluble drug to increase its dissolution rate there by its bioavailability. Materials and Methods: The preformulation ...

AIMS Myocardial perfusion imaging during hyperaemic stress is commonly used to detect coronary artery disease. The aim of this study was to investigate the relationship between left ventricular global longitudinal strain (GLS), strain rate (GLSR), myocardial early (E') and late diastolic velocities (A') with adenosine stress first-pass perfusion cardiovascular magnetic resonance (CMR) imaging. ...

BACKGROUND Women who have coronary artery disease (CAD) often present with atypical symptoms that may lead to misdiagnosis. We assessed strain, systolic strain rate and left ventricular dyssynchrony with 2- dimensional- speckle tracking echocardiography to evaluate its use as a non-invasive method for detecting CAD in women with normal ejection fraction compared with healthy women controls with...

Many microbes bind and adhere via adhesins to host cell carbohydrates as an initial step for infection. Therefore, cell lines expressing Lewis b (Le(b)) determinants were generated as a potential model system for Helicobacter pylori colonization and infection, and their expression of blood group Lewis determinants was characterized. CHO-K1 cells were stably transfected with selected glycosyltra...
