Assessment of Urinary F2-Isoprostanes in Experimental and Clinical Studies: Mass Spectrometry Versus ELISA To the Editor: Ojeda and colleagues reported that oxidative stress renal markers contribute to sex differences in blood pressure in adult growth-restricted offspring rats. The antibody used in the ELISA kit used by Ojeda et al isspecificfor15(S)-8-iso–PGF2 , 2 (http://www.oxfordbiomed.com/...

Objective(s) Several studies have reported improved response of exercised hearts to myocardial infarction (MI). This study was aimed to evaluate the preventive role of treadmill exercise and diosgenin on cardiac marker enzymes, thiobarbituric acid reactive substances (TBARS), total antioxidant status (TAS), lipids, and electrocardiographic (ECG) patterns in isoproterenol (ISO)-induced myocardi...

1) RFC 892 is an older version of the ISO Transport Protocol Specification. Therefore this RFC should be assumed to supercede RFC 892. 2) This document has been prepared by retyping the text of ISO/TC97/SC16/N1576 and then applying proposed editorial corrections contained in ISO/TC97/SC16/N1695. These two documents, taken together, are undergoing voting within ISO as a Draft International Stand...

Activation of cAMP-dependent protein kinase A (PKA) in ventricular myocytes by isoproterenol (Iso) causes phosphorylation of both phospholamban (PLB) and troponin I (TnI) and accelerates relaxation by up to twofold. Because PLB phosphorylation increases sarcoplasmic reticulum (SR) Ca pumping and TnI phosphorylation increases the rate of Ca dissociation from the myofilaments, both factors could ...

To obtain effective data from a medical instrument, instrument calibration, an important process within the laboratory activities, is required. Many mobile medical devices are widely and routinely utilized for monitoring people’s physiological data by home-care users. However, it is necessary to let these test data be as effective as laboratory reports, so physicians can recognize as well as re...

After a long-standing tradition of analytical quality and analytical quality control programs, most medical laboratories that are aware of the need for total quality management, are experiencing new systems designed to assure quality throughout the entire total testing process, from the pre-analytical to the post-analytical steps. The availability of a new International Standard, ISO 15189:2003...
