Previous studies with intact maize plants have shown an apparent induction of nitrate uptake capacity when plants are transferred to a nitrate containing nutrient solution. Whether this phenomenon reflects a change in nitrate carrier activity at the membrane level or an effect of nitrate metabolism has not been determined as yet due to the complexity of investigating nitrate transport with intact tissue. The use of a membrane vesicle approach has also been limited by the time associated with conventional membrane isolation methods. In this study, an improved plasma membrane isolation method was developed and made it possible to investigate plasma membrane nitrate carrier activity at the membrane level.

Physiological background concerning mechanics of the respiratory system, techniques of measurement and clinical implications of pressure-volume curve measurement in mechanically ventilated patients are discussed in the present review. The significance of lower and upper inflection points, the assessment of positive end-expiratory pressure (PEEP)-induced alveolar recruitment and overdistension and rationale for optimizing ventilatory settings in patients with acute lung injury are presented. Evidence suggests that the continuous flow method is a simple and reliable technique for measuring pressure-volume curves at the bedside. In patients with acute respiratory failure, determination of lower and upper inflection points and measurement of respiratory compliance should become a part of the routine assessm...
