Cognitive function in postmenopausal women receiving letrozole or tamoxifen as adjuvant endocrine treatment was compared during the fifth year of treatment in a substudy of the BIG 1-98 trial. In BIG 1-98 patients were randomized to receive adjuvant (A) 5-years tamoxifen, (B) 5-years letrozole, (C) 2-years tamoxifen followed by 3-years letrozole, or (D) 2-years letrozole followed by 3-years tam...
چکیده در این پایان نامه تلاش شده است که بر روی یک قطعه مجتمع بسیار مهم به نام چرخشده نوری (optical circulator) که در مخابرات تار نوری کاربرد دارد پژوهش نظری انجام شود. بعد از مرور کاربرد های این قطعه و تشریح فیزیکی نحوه ی عملکرد آن به مرور مفاهیم پایه برای طراحی یک نمونه از این قطعات خواهیم پرداخت. مفاهیم اساسی مورد استفاده در این پایان نامه شامل مگنتواپتیک و بلورهای فوتونی هستند. در مگنتواپتی...
AIMS Inhibition of neutral endopeptidases (NEP) results in a beneficial increase in plasma concentrations of natriuretic peptides such as ANP. However NEP inhibitors were ineffective anti-hypertensives, probably because NEP also degrades vasoconstrictor peptides, including endothelin-1 (ET-1). Dual NEP and endothelin converting enzyme (ECE) inhibition may be more useful. The aim of the study wa...
BACKGROUND Circulating N-terminal pro-B-type natriuretic peptide (NT pro-BNP), high- sensitivity C-reactive protein (hs-CRP) and big endothelin (big-ET) have been shown to be increased in heart failure and to contribute to both hemodynamic deterioration and cardiovascular remodeling. Here, we examined the prognostic value of the three neurohormones at admission in a population of hospitalized p...
In this paper, the effect of microstructure on the thermal conductivity of plasma-sprayed Y2O3 stabilized ZrO2 (YSZ) thermal barrier coatings (TBCs) is investigated. Nine freestanding samples deposited on aluminum-base superalloy are studied. Cross-section morphology such as pores, cracks, m-phase content, grain boundary density of the coated samples are examined by scanning electron microscopy...
