The purpose of this study was to evaluate the potential of magnetic resonance imaging (MRI) in vivo for the characterization of tissue changes associated with acute myocardial rejection after cardiac transplantation. Of 15 dogs that underwent heterotopic cardiac transplantation, six served as untreated controls, and nine received immunosuppressive therapy (25 mg/kg/day cyclosporine, 1 mg/kg/day...
Methods Thirty-one stable, African-American outpatients with SCD (mean age 32±8 yrs) prospectively underwent CMR (Philips 1.5 Tesla) and TTE (Philips iE33). Retrospectivelygated cines of left ventricular (LV) 2-, 3-, and 4-chamber, and short axis cine stack were obtained using SSFP (temporal resolution 25-40ms). Late gadolinium enhancement (LGE) images of the same views were obtained 10-20 minu...
Background: The present study aimed to compare the clinical efficacy and safety profile of Ziferon and Betaferon. Objectives: In total, 41 consecutive patients with relapsing forms of Multiple Sclerosis (MS) were selected from the MS outpatient clinic affiliated to Tehran University of Medical Sciences. The patients were randomly assigned into two groups. Methods: Each group either received Z...
Good evaluation variables are needed to study postweaning lag in early weaned pigs. In this study, performance, digestibility, concentration of blood components and aerobic fecal microflora under different dietary regimens from weaning at 3 wk of age to 35 d of age are reported. Treatment 1 (T1) consisted of a corn-soybean meal starter diet. Pigs in treatment 2 (T2) received a steamed, rolled o...
The paper presents a three-mass rheological model of the system "soil – vibration plate base frame". makes it possible to reproduce different modes interaction between vibratory and soil: with types decoupling without decoupling. We verify this by comparing experimental values vertical oscillation span frame Zitrek CNP 20 vibrating previously calculated values. As whole, oscillations correlate ...
This study was aimed to investigate the effects of L-carnitine (Car), creatine monohydrate (CrM) and their combination (CarCrM) as dietary antioxidants materials on productive performance, digestibility, ileal eubiosis, blood chemistry redox system stressed quails challenged by lead acetate (LA) in drinking water. In total, 600 were assigned into 5 treatments with 4 replications each 30 chicks ...
We investigate the problem of automatically labelling appearances of characters in TV or film material with their names. This is tremendously challenging due to the huge variation in imaged appearance of each character and the weakness and ambiguity of available annotation. However, we demonstrate that high precision can be achieved by combining multiple sources of information, both visual and ...
Introduction: Higher diffusion weighting (b-values) in diffusion-weighted imaging (DWI) is increasingly used to detect pelvic and bone malignancies. The low apparent diffusion coefficient (ADC) and longer T2 values of tumours make them visible at high b-values in comparison to the background tissue, which is largely suppressed. However, large b-values (especially > 1000 s mm) can cause severe i...
