A deep inspiration (DI) produces bronchodilation in healthy individuals. Conversely, in asthmatics, DIs are less effective in producing bronchodilation and can cause more rapid airway renarrowing and even bronchoconstriction in moderate to severe asthmatics. It is noteworthy that the manner by which a DI is able to cause bronchoconstriction via a stretch-activated contraction (R(stretch)) is th...

Developments of liquid-scintillation counting as a practical method for the assay of radioisotopes in biological samples followed work by Reynolds, Harrison & Salvini (1950) and Kailmann & Furst (1950). Reviews of progress and developments in liquid-scintillation counting have been given by Davidson & Fiegelson (1957) and Bell & Hayes (1958). Guinn (1958) and Stitch (1959) have reviewed the adv...

The aldol-Tishchenko reaction of enolizable aldehydes is a simple and effective way to prepare 1,3-diol monoesters, which are widely used as coalescing agents in the paint industry. The use of monoalcoholates of 1,3-diols as catalysts gives fast and clean reactions compared with the previous use of several inorganic catalysts. The use of the proper 1,3-diol moiety in the catalyst also reduces t...
