All regulatory organizations are paying close attention to the identification and measurement of genotoxic contaminants. Using conventional analytical techniques like high-performance liquid chromatography (HPLC) gas quantify probable substances (PGIs) at trace level is difficult (GC). Therefore, there a necessity for advanced development highly sensitive procedures determination trace-level PG...

The hyperthermophilic crenarchaeon Aeropyrum pernix contains phosphoglucose isomerase (PGI) activity. However, obvious homologs with significant identity to known PGIs could not be identified in the sequenced genome of this organism. The PGI activity from A. pernix was purified and characterized. Kinetic analysis revealed that, unlike all known PGIs, the enzyme catalyzed reversible isomerizatio...

Background—PPHN is associated with decreased lung angiogenesis and impaired pulmonary vasodilatation at birth. Prostanoids are important modulators of vascular tone and angiogenesis. We hypothesized that altered levels of prostacyclin (PGI2), a potent vasodilator, and thromboxane (TXA2), a vasoconstrictor, contribute to impaired angiogenesis of pulmonary artery endothelial cells (PAEC) in PPHN....

We have evaluated the effect of delivering nitric oxide using a continuous flow system (CFS) or two commercially available proportional gas injection systems (PGIS), Nodomo (Dräger, Lübeck, Germany) and Pulmonox-Mini (Messer Griesheim Austria, Gumpoldskirchen, Austria) on measured and simulated concentrations of nitric oxide. Nitric oxide concentration was measured in a bench test at five sites...

The key component in community mapping is the inclusion of local spatial knowledge. The essence of the method is not the tools for drawing maps, or using the GPS and GIS, but the enhanced possibilities for acquiring and sharing local spatial knowledge, The idea that local spatial knowledge is a vital resource – not only for the community themselves, but for various legitimate outsiders is made ...

To cope with the ever growing problem of traffic and parking management this paper proposes an automated guidance and management for user to park the car. The nodes transmit the information through wireless sensor network by tree-like topological structure using ZigBee. After analyzing and processing the data, the information and Management center would distribute the parking information by LED...

Plant growth inhibitors (PGIs) in rice (Oryza sativa), or allelochemicals, are secondary metabolites that either exudated by plants to cope with natural competitors produced during the decomposition of by-products paddy fields. Of these, major groups PGIs include phenolics, flavonoids, terpenoids, alkaloids, steroids, and fatty acids, which also exhibit potential medicinal pharmaceutical proper...
