BACKGROUND The mechanisms through which exercise reduces cardiovascular disease are not fully understood. We used echocardiograms, cardiac biomarkers and gene expression to investigate cardiovascular effects associated with exercise training. METHODS Nineteen sedentary men (22-37 years) completed a 17-week half-marathon training program. Serial measurements of resting heart rate, blood pressu...
OBJECTIVES To investigate pregnancy outcomes in women who have previously given birth to a baby weighing less than 2500 grams in a population in which the low birthweight rate is high. METHODS We compared the obstetric performance of 100 women who had delivered a low birthweight baby (<2500g) at term in a previous pregnancy (cases) with those of 100 women who were matched for age, height, bod...
Performance of the Wisconsin Card Sorting Test (WCST) and related brain-activation patterns reflect both task learning and execution. Normal subjects learned the WCST prior to performance during slow SPECT ligand infusion. Blood flow increased in bilateral inferior frontal, right middle and inferior parietal cortices. Activity decreased in hippocampi, temporal cortex, anterior cingulate and cau...
There is a growing interest in the modeling and control of model helicopters using nonlinear dynamic models and nonlinear control. Application of a new intelligent control approach called Brain Emotional Learning Based Intelligent Controller (BELBIC) to design autopilot for an autonomous helicopter is addressed in this paper. This controller is applied to a nonlinear model of a helicopter. This...
Rhodococcus equi infection produces an insidious disease in foals 1 to 4 months of age, with intrapulmonary and extrapulmonary abscessation and organ dysfunction as common sequelae. Although amenable to treatment, this foalhood pneumonia has an impact on later athletic performance that has remained controversial. Christley and Hodgson1 noted that <64% of their recovered hospital cases (n 5 11) ...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
efficiency of enzymes which are used in industrial or environmental applications is highly dependent on their thermal stability. in this study, the stability of dfpase has been evaluated after introducing disulfide bonds to the structure. the results obtained from a series of protein design software were subjected to molecular dynamics simulation at different temperature to test the performance...
