background and objectives: public-private partnership (ppp) is a well-established model to alleviate the risk of investment in health domain. while the model is widely applied in the developed countries, the adoption of the model in many developing countries is hampered partly by the lack of knowledge on dimensions and requirements of its local implementation. the present study, thus, aimed to ...
Pustulosis palmaris et plantaris (PPP) is a chronic relapsing skin disease characterized by sterile intraepidermal pustules and, usually, by scaly erythematous skin on the palm, soles, or both. To determine the primary pathogenic factors involved in the onset of PPP, we analyzed the implications of heat shock proteins (HSPs), which are highly conserved immunogenic proteins, chronic microbial in...
Examining the interrelationships among critical success factors (CSFs) for public private partnership (PPP) projects is of importance for improving PPP project performance and maintaining the sustainability of PPP project implementation. Previous studies mostly focused on the identification of the CSFs for PPP projects; limited studies investigated the interrelationships among CSFs. Hence, the ...
اثر تاخیر تروپوسفر بعنوان یکی از منابع خطا در کار با سامانه های تعیینموقعیت ماهوارهای است. این خطا که منشا فیزیکی دارد و ماهیت آن مانع از حذف کامل آن با استفاده از مدلها میشود، یکی از موثرترین خطاها در سامانههای ماهوارهای است که چشمپوشی از آن و یا برآورد نشدن صحیح آن تاثیر بسیار زیادی در دقت تعیین موقعیت دارد. از آنجا که در هیدروگرافی بیشترین استفاده از سامانههای GNSS در حالت کینماتیک...
The pentose phosphate pathway (PPP) plays a critical role in macromolecule biosynthesis and maintaining cellular redox homoeostasis in rapidly proliferating cells. Upregulation of the PPP has been shown in several types of cancer. However, how the PPP is regulated to confer a selective growth advantage on cancer cells is not well understood. Here we show that glucose-6-phosphate dehydrogenase (...
Relative population growth affects relative prices through the so-called BalassaSamuelson (BS) mechanism and that in turn impacts PPP. This paper empirically investigates the relationship between PPP exchange rate and relative population growth in a panel of 80 selected countries. Following the Balassa-Samuelson hypothesis this paper argues that relative population growth affects nominal wages ...
BACKGROUND AND PURPOSE Tortuous, engorged veins can be identified on the venous phase of the brain circulation in patients with venous congestion related to an intracranial dural arteriovenous fistula (DAVF). The term pseudophlebitic pattern (PPP) has been used to describe this finding. The purpose of this study was to determine the prevalence of PPP in patients with intracranial DAVF and to an...
OBJECTIVE Acute lung injury still accounts for postoperative mortality after cardiopulmonary bypass (CPB). The safety and the efficacy of pulsatile pulmonary perfusion (PPP) during CPB were analyzed. Preliminary results of the first PPP trial in human beings are reported. METHODS Thirty low-risk coronary artery bypass grafting (CABG) patients were prospectively randomized to receive PPP with ...
Cerebral pentose phosphate pathway (PPP) activity has been linked to NADPH-dependent anabolic pathways, turnover of neurotransmitters, and protection from oxidative stress. Research on this potentially important pathway has been hampered, however, because measurement of regional cerebral PPP activity in vivo has not been possible. Our efforts to address this need focused on the use of a novel i...
BACKGROUND Palmoplantar pustulosis (PPP) is a recalcitrant chronic inflammatory skin disease. Data relevant for the medical care of patients with PPP are scarce. Thus, the aim of this work was to investigate the disease burden, clinical characteristics, and comorbidity of PPP patients in Germany. PATIENTS AND METHODS PPP patients were examined in a crosssectional study at seven specialized ps...
