BACKGROUND Systemic inflammation has been implicated in several chronic diseases. GlycA is a new nuclear mass resonance (NMR) spectroscopy-derived biomarker of systemic inflammation that reflects protein glycosylation. We evaluated the association of GlycA with albuminuria and eGFR in the ELSA-Brasil Study. METHODS The cross-sectional association between GlycA (automated NMR LipoProfile(®) te...
The narrow Gaussian-length-distribution of actin filaments forming the cytoskeleton of the human erythrocyte indicates the existence of strict mechanisms for length determination and maintenance. A similar regulation is achieved in striated muscle by the capping of both the ends of the thin filaments, which consequently prevents monomer exchange. However, the ability of erythroid cytoskeletal p...
The aim of this study was to measure marginal fit at cylinder-abutment interface, before and after overcasting procedure. A hexagonal implant was fixed to a stainless steel base and a Estheticone-like abutment used during all the experiment. Before casting procedure, gold (Group I) and Ni-Cr-Be (Group II) premachined cylinders were tightened to the abutment with gold and titanium screws (in bot...
اﻧﺪازهﮔﯿﺮی و ﺗﺤﻠﯿﻞ ﺷﺎﺧﺺﻫﺎی ﺑﻬﺮهوری آب در روش‌های مختلف آبیاری (سطحی و تحت فشار) ﺑﻪ ﻋﻠﺖ ﻣﺤﺪودﯾﺖ ﮐﻤﯽ و ﮐﯿﻔﯽ اﯾﻦ نهاده ارزﺷﻤﻨﺪ از ﺟﺎﯾﮕﺎه ﺧﺎﺻﯽ ﺑﺮﺧﻮردار اﺳﺖ. هدف از این پژوهش مقایسه بهرهوری آب و بهرهوری اقتصادی آن در سیستمهای آبیاری بارانی و سطحی است. در این راستا از اطلاعات و دادههای تفصیلی سیستمهای آبیاری و عملکرد محصولات تحت کشت این سیستمها در سال 1390 در دشت قزوین استفاده شده است.اطلاعات...
© 1995-2012 IEEE. We present the first reliability study of InAs/GaAs self-assembled quantum dot lasers epitaxially grown on Ge/Si substrates. Some devices maintain lasing oscillation after more than 2700 h of constant current stress at 30 °C, longer than any previous life tests of GaAs lasers epitaxially grown on silicon. No catastrophic failures were observed. The lasers were characterized to...
BACKGROUND Evidence-based guidelines on optimal perioperative fluid management have not been established, and recent randomized trials in major abdominal surgery suggest that large amounts of fluid may increase morbidity and hospital stay. However, no information is available on detailed functional outcomes or with fast-track surgery. Therefore, we investigated the effects of two regimens of in...

Background: Adolescence includes a period (10 to 19 years) of profound biopsychosocial changes, constituting potentially difficult challenges, which may become more pronounced in the presence of a chronic condition and its limitations. Responses are not homogeneous and can be quite variable, depending on various specific individual factors. Research comparing adolescents with or without chronic...
Most analysts disagree upon whether photovoltaic systems (PV) will be able to play an important role in the energy scenarios of the future. A few scholars also question the appropriateness of policies that envisage the use of public subsidies to stimulate the growth of this industry and to accelerate market penetration. This paper contributes to this debate by examining whether carefully design...
OBJECTIVES To compare the effectiveness and cost-effectiveness of a promising new point-of-care (POC) chlamydia test with traditional nucleic acid amplification testing (NAAT), and to determine the characteristics that would make a POC test most cost-effective. METHODS A decision tree was constructed to model chlamydia screening visits to a sexually transmitted disease clinic by a hypothetica...
