Pulmonary biosynthesis and metabolism of prostaglandins and related substances.

Pulmonary biosynthesis and metabolism of prostaglandins and related substances.

On passage through the lung vascular bed, prostaglandins are removed from the circulation by a transport carrier and subsequently inactivated by intracellular enzymes. However, PGI2 is not inactivated by the lung in vivo. Although PGI2 is an excellent substrate for the intracellular enzymes in vitro, PGI2 is not a substrate for the carrier system. Thus, the transport carrier determines which ci...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

Introduction to the biosynthesis and metabolism of prostaglandins.

Biosynthesis of prostaglandins from arachidonic acid in guinea pig lung. Prostaglandins and related factors. 38.

The prostaglandins constitute a class of physiologically active compounds with a widespread occurrence in animal tissues (see References 2 and 3). Previous studies have led to the determination of their structures (4-S), and more recent investigations have shown that they can be formed enzymatically from the essential fatty acids (7,8). It was thus shown that in homogenates of vesicular glands ...

the relationship between field-related cognitive styles and global reading comprehension of hypertext

this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...
