Retinomotor and Diurnal Rhythm in Crustaceans

Diurnal Rhythm of Potassium

There has been a GREAT deal of BB (Bulletin Board) discussion about potassium. Such discussion has been devoted not only to its importance in general but also specifically to AF. There have been many anecdotal stories testifying to the latter. On the other hand, I’m sure there are many LAFers that are unable to detect any appreciable benefit from potassium supplementation. Perhaps there is an e...

Diurnal rhythm of asthma.

A diurnal rhythm in the occurrence and severity of asthma symptoms is almost universal with disturbed sleep due to enhanced symptoms at night paralleled by a change in lung function. The mechanisms involved are not completely understood. However, it appears to be related to an exaggerated response to a circadian rhythm in lung function observed in healthy individuals. The circadian nature of as...

Diurnal rhythm of CrossLaps in human serum.

attributable to the use of a particle-enhanced nephelometric immunoassay (14 ) in the present study in contrast to previous studies (11, 12, 16) using a particle-enhanced turbidimetric immunoassay (10 ). Method calibration is not yet established internationally but is required to allow direct comparison between methods (18 ). In children .1 year, serum creatinine increases with age until adulth...

Effects of Orcadian Rhythm and cAMP on Retinomotor Movements in the Green Sunfish, Lepomis cyanellus

The photoreceptors and retinal pigmented epithelium (RPE) of teleosts undergo diurnal changes in position in response to day/night changes in light conditions. These position changes, called retinomotor movements, may also persist under conditions of constant darkness. In this study, the authors have compared the retinomotor movements of rods, cones, and RPE under conditions of constant darknes...
