A novel MS/MS-based analysis strategy using isotopomer labels, referred to as "tandem mass tags" (TMTs), for the accurate quantification of peptides and proteins is described. The new tags are designed to ensure that identical peptides labeled with different TMTs exactly comigrate in all separations. The tags require novel methods of quantification analysis(More)
AIMS We aimed to document the drug management of patients at high cardiovascular risk in daily practice, with the special focus on lipid-lowering treatment. METHODS AND RESULTS In this prospective noninterventional study in 2387 outpatient centers throughout Germany, a total of 13,942 high-risk patients (mean age 65.7 years, 61.6% males) were treated with(More)
AIMS Disease management programs (DMP) for diabetes mellitus (DM) or coronary heart disease (CHD) address the treatment of lipid disorders. The current registry aimed to compare drug utilization, lipid lowering effects and further outcomes of outpatients at high cardiovascular risk in DMP for DM or CHD compared to patients in routine care (no-DMP).

BACKGROUND Cytochrome P450 (CYP) 2J2 is expressed in the vascular endothelium and metabolizes arachidonic acid to biologically active epoxyeicosatrienoic acids (EETs). The EETs are potent endogenous vasodilators and inhibitors of vascular inflammation. However, it is not known whether genetic polymorphisms of CYP2J2 are associated with increased(More)
Osteoprotegerin (OPG) antagonizes receptor activator of nuclear factor-kappaB ligand (RANKL), the principal regulator of osteoclasts. Of note, OPG-deficient mice display osteoporosis and arterial calcification. Recently, OPG gene polymorphisms have been associated with osteoporosis and early predictors of cardiovascular disease. In this study, we examined(More)
Proliferation and differentiation of mammary epithelial cells are governed by hormonal stimuli, cell-cell, and cell-matrix interactions. Terminal differentiation of mammary epithelial cells depends upon the action of the lactogenic hormones, insulin, glucocorticoids, and prolactin that enable them to synthesize and secrete milk proteins. These(More)
Familial defective apolipoprotein (apo) B-100 (FDB) is a frequent cause of hypercholesterolemia. Hypercholesterolemia in homozygous FDB is less severe than in homozygotes for familial hypercholesterolemia. Recently, we showed decreased low density lipoprotein (LDL) apoB-100 fractional catabolism and decreased production of LDL due to an enhanced removal of(More)
BACKGROUND Determination of bone age is routinely used for following up substitution therapy in congenital adrenal hyperplasia (CAH) but today is a procedure with significant subjectivity. OBJECTIVE The aim was to test the performance of automatic bone age rating by the BoneXpert software package in all radiographs of children with CAH seen at our clinic(More)
Lifibrol (4-(4'-tert-butylphenyl)-1-(4'carboxyphenoxy)-2-butanol) is a new hypocholesterolemic drug effectively reducing total cholesterol, LDL cholesterol, and apolipoprotein (apo) B in experimental animals and in humans. In contrast to fibrates and HMG-CoA reductase inhibitors the cholesterol and triglyceride lowering effect of Lifibrol is not accompanied(More)
