Erythrocytic adenosine deaminase in post myocardial infarction angina patients

A comparative study on the levels of erythrocyte adenosine deaminase and lipid peroxidation has been undertaken in post myocardial infarction angina patients along with age and sex matched healthy individuals serving as control. Present findings show that levels of adenosine deaminase is highly elevated in post myocardial infarction angina patients compared to healthy persons. Malondialdehyde levels are also significantly increased in post myocardial infarction angina patients. The study shows that adenosine deaminase has an important implication in ischemic myocardial syndrome.

Extracting invariable fault features of rotating machines with multi-ICA networks

This paper proposes novel multi-layer neural networks based on Independent Component Analysis for feature extraction of fault modes. By the use of ICA, invariable features embedded in multi-channel vibration measurements under different operating conditions (rotating speed and/or load) can be captured together. Thus, stable MLP classifiers insensitive to the variation of operation conditions are constructed. The successful results achieved by selected experiments indicate great potential of ICA in health condition monitoring of rotating machines.

Human bone marrow-derived mesenchymal stem cells transplanted into damaged rabbit heart to improve heart function

INTRODUCTION Congestive heart failure is the end stage of manycardiovascular diseases. Myocardial infarction (MI)is a life-threatening event that may cause suddencardiac death and heart failure. Despite considerableadvances in diagnosis and treatment of heart disease,cardiac dysfunction after MI is still the majorworldwide cardiovascular disorder. Damaged myo-cardium after acute MI is gradually replaced by fi-brotic noncontractile cells to form scar tissue. Thedeveloping ventricul…
