DIURNAL VARIATIONS IN PLASMA LIPIDS

Diurnal Variations in Plasma Lipids*

The concentration of lipids in the blood of animals and man is commonly considered to be a labile value which is affected markedly by the ingestion of food. This belief is reflected in the usual practice of securing samples of blood for comparative lipid studies with the subject in a fasting state. The same belief underlies the insistence on blood obtained during fasting in performing other ana...

Diurnal variations in milk macro-mineral concentrations in Holstein dairy cows in Urmia, Iran

Milk samples from high and low milk producer Holstein cows, were obtained during the morning and afternoon milking over a one week period. Overall, 1064 samples were tested within 14 times sampling in Urmia, Iran. Milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. The highest and lowest concentrations were obse...

Diurnal variations in myocardial metabolism.

The heart is challenged by a plethora of extracellular stimuli over the course of a normal day, each of which distinctly influences myocardial contractile function. It is therefore not surprising that myocardial metabolism also oscillates in a time-of-day dependent manner. What is becoming increasingly apparent is that the heart exhibits diurnal variations in its intrinsic properties, including...
