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...

Diffuse proliferative glomerulonephritis without IgA deposits (DPGN) in patients with pustulosis palmaris et plantaris (PPP) is described. This association has not been previously reported. Although PPP was resolved transiently after tonsillectomy, it was worsened coincidently at the time of exacerbation of DPGN. Improvement of proteinuria and PPP was observed after antiplatelet therapy. It was...

In this study, an efficient purification method for the polyphenols of Pinus koraiensis pinecone (PPP) has been developed. AB-8 resin was verified to offer good adsorption and desorption ratio for PPP. Response surface methodology (RSM) indicated that the optimized purification parameters for PPP were 1.70 mg GAE/mL phenolic sample concentration, 22.00 mL sample volume, and 63.00% ethanol conce...

The continuity and reliability of precise GNSS positioning can be seriously limited by severe user observation environments. The Inertial Navigation System (INS) can overcome such drawbacks, but its performance is clearly restricted by INS sensor errors over time. Accordingly, the tightly coupled integration of GPS and INS can overcome the disadvantages of each individual system and together fo...
