background: l-carnitine has been demonstrated to confer cardiac protection against ischemia reperfusion injury in animals. this study evaluates the effects of l-carnitine administration on cardiac biomarkers after coronary artery bypass graft (cabg) surgery. methods: one hundred thirty-four patients undergoing elective cabg surgery, without a history of myocardial ischemia or previous l-carniti...

in this study, cross linked chitosan resin (ccr) was prepared by cross linking chitosan with glutaraldehyde, and then î±-ketoglutaric acid-modified chitosan resin (kcr) was obtained by modifying ccr with î±-ketoglutaric acid. the sorption behavior of methylene blue (mb) on kcr and ccr from aqueous solution was investigated. the effect of various experimental parameters (e.g. initial ph, sorbent...

We address the problem of evaluation multiloop Feynman integrals by means their Mellin-Barnes representation. After a brief overview available capabilities through open source toolkits and application in various circumstances, we introduce new code MBcreate which allows one to automatically deduce concise representation for given parametric integral. A thorough discussion its implementation use...

the weighted semigroup algebra mb (s, w) is studied via its identification with mb (s) together with a weighted algebra product *w so that (mb (s, w), *) is isometrically isomorphic to (mb (s), *w). this identification enables us to study the relation between regularity and amenability of mb (s, w) and mb (s), and improve some old results from discrete to general case.
