BACKGROUND Glow discharge plasma (GDP) procedure is an effective method for grafting various proteins, including albumin, type I collagen, and fibronectin, onto a titanium surface. However, the behavior and impact of titanium (Ti) surface modification is yet to be unraveled. PURPOSE The purpose of this study is to evaluate and analyze the biological properties of fibronectin-grafted Ti surfac...

This paper uses Johansen multivariate cointegration analysis to examine the relationship between health and GDP for 13 OECD countries over the last two centuries, for periods ranging from 1820-2001 to 1921-2001. A similar, long run, cointegrating relationship between life expectancy and both total GDP and GDP per capita was found for all the countries estimated. The relationships have a signifi...

Despite all theoretically and empirically motivated criticism of GDP as a social welfare and progress indicator, its role in economics, public policy, politics and society continues to be influential. To resolve this paradox, one has to recognize that many economists accept the criticism of the GDP indicator but deny its relevance. This paper evaluates the reasons for denial. This entails five ...

Fluoride activation of the cGMP cascade of vision requires the presence of aluminum, and is shown to be mediated by the binding of one A1F-4 to the GDP/GTP-binding subunit of transducin. The presence of GDP in the site is required: A1F-4 is ineffective when the site is empty or when GDP beta S is substituted for GDP. This sensitivity to the sulfur of GDP beta S suggests that A1F-4 is in contact...

This paper uses Johansen multivariate cointegration analysis to examine the relationship between health and GDP for thirteen OECD countries over the last two centuries, for relationship between life expectancy and both total GDP and GDP per capita was found for all of the countries estimated. The relationships have a significant influence on both total GDP and GPD per capita in most of the coun...

BACKGROUND Glucose degradation products (GDP) are an important factor that contribute to bioincompatibility of peritoneal dialysis fluids. These substances are generated in the dialysis fluid during heat sterilization. Several approaches have been proposed to reduce the content or toxicity, or both, of GDP present in the dialysis fluid. We examined whether L-2-oxothiazolidine-4-carboxylic acid ...

Bioincompatibility of peritoneal dialysis fluids (PDF) has been linked to the presence of glucose degradation products (GDP). Previous experiments have shown that short-term exposure to several GDP at concentrations found in commercially available PDF had no significant effect on human peritoneal mesothelial cells (HPMC). During continuous ambulatory peritoneal dialysis, however, cells are cont...

یکی از عوامل محرک برای ایجاد جریان محوری درون روتور سانتریفیوژ به منظور افزایش عملکرد جداسازی، اسکوپ است. با توجه قرار گرفتن در معرض گاز ماخ بالا، دچار شوک شده و گرادیان‌های شدیدی اتفاق خواهد افتاد. این پژوهش اطراف حالت دوبعدی (r-θ) روش شبیه­سازی مستقیم مونت‌کارلو (DSMC) استفاده حل­گر dsmcFoam فواصل مختلف دیواره شبیه‌سازی نتایج نشان می‌دهد که فاصله کاهش زاویه برخورد اسکوپ، سبب بیشینه دما نیروی ...
