I was very honored to receive the University of California, San Francisco, and the International Society of Pharmacometrics Lewis Sheiner lecturer award in May 2013. In the present perspective, I outline the main points of my lecture at the American Conference of Pharmacometrics (slides in Supplementary Material 1). I first emphasize the scientific contributions of Lewis Sheiner as a quantitati...

Few studies have investigated the effect of exercise on homocysteine and 15-F21-isoprostane in animal models. The present study was designed to examine the effect of long-term exercise and/ or high cholesterol diet on MDA, 15-F21-isoprostane and total homocysteine in the aorta and plasma of rabbits. Methods: 56 male rabbits were divided into four groups: normal diet (control), normal diet wi...

Background: Considerable evidence suggests that oxidative stress affects diabetes mellitus (DM) and contributes to its complications. Vitamin D has been shown to possess antioxidant properties. The aim of this study was to determine the association between serum levels of calcifediol (25-OH-D), an indicator of vitamin D status, and lipid profiles with oxidative stress in patients with type 2 di...

BACKGROUND Exhaled breath condensate (EBC) 8-isoprostane levels were found increased in chronic obstructive pulmonary disease. However, the relation between EBC 8-isoprostane and parameters which have a known predictive value in COPD, remains vastly unknown, and so does subsequently its clinical value. OBJECTIVES To investigate the relationship between 8-isoprostane level in EBC and clinical ...

OBJECTIVES The purpose of this study is to understand whether isoprostane, a biomarker of oxidative stress, is subject to heritable control; whether it shares heritability with other cardiometabolic risk traits; and finally whether genetic variation at a specific candidate locus contributes to isoprostane variability. BACKGROUND Isoprostane marks oxidative stress, and elevated isoprostane exc...

few studies have investigated the effect of exercise on homocysteine and 15-f21-isoprostane in animal models. the present study was designed to examine the effect of long-term exercise and/ or high cholesterol diet on mda, 15-f21-isoprostane and total homocysteine in the aorta and plasma of rabbits. methods: 56 male rabbits were divided into four groups: normal diet (control), normal diet with ...

Oxidative stress has an important role in the pathogenesis of asthma. 8-Isoprostane is a prostaglandin (PG)-F2-like compound belonging to the F2 isoprostane class that is produced in vivo by the free radical-catalyzed peroxidation of arachidonic acid. 8-Isoprostane is a biomarker of oxidative stress, and its concentration is increased in the bronchoalveolar lavage fluid of patients with interst...

BACKGROUND There have been limited numbers of studies on patients with chronic kidney disease (CKD) to determine oxidative stress in exhaled breath condensate (EBC). Those two studies have been carried out on hemodialysis patients, and hydrogen peroxide and nitric oxide have been studied in order to show oxidative stress on EBC. AIMS We investigated oxidative stress in EBC evaluating 8-isopro...

background: it has been proposed that oxidative stress plays an important role in male infertility. the aims of this study were to compare seminal plasma levels of 15-f2t-isoprostane (8-iso-pgf2?), malondialdehyde (mda), and total (sum of free and bound) homocysteine (thcy) in normozoospermic vs. asthenozoospermic men, and to examine the relationships between thcy and lipid peroxidation product...

OBJECTIVE Increased levels of 8-isoprostane were found in various human lung diseases suggesting 8-isoprostane as a marker of pulmonary oxidative stress in vivo. The exact role in pediatric lung diseases has not been defined yet. The goal of this study was to clarify the role of 8-isoprostane in nasally exhaled breath condensate as possible marker of oxidative stress in children with different ...
