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...

One-lung ventilation is routinely used to facilitate exposure for thoracic surgical procedures and can be achieved via several lung isolation techniques. The optimal method for lung isolation depends on a number of factors that include (1) the indication for lung isolation, (2) anatomic features of the upper and lower airway, (3) availability of equipment and devices, and (4) the anesthesiologi...

The POWER4-based p690 systems offer the highest performance of the IBM eServer pSeries line of computers. Within the general-purpose UNIX server market, they also offer the highest levels of concurrent error detection, fault isolation, recovery, and availability. High availability is achieved by minimizing component failure rates through improvements in the base technology, and through design t...

There have been parallel advancements in pediatric airway equipment, including the development of pediatric sized bronchial blockers, Univent tubes, and double lumen tubes, providing the ability to isolate the lung in pediatric patients as small as full term neonates. Despite this widespread ability, there remain significant regional differences in the use of lung isolation techniques, some cen...
