BACKGROUND
Even though the catecholamines (dopamine, norepinephrine and epinephrine) have been detected in plants their role is poorly documented. Correlations between norepinephrine, soluble sugars and starch concentration have been recently reported for potato plants over-expressing tyrosine
The aim of the study was to investigate the influence on coagulation and platelet function of two 6% medium molecular weight hydroxyethylstarch solutions (HES, MW 200,000, DS 0.5) made of potato (K) and corn (M) starch. Twenty patients undergoing elective vertebral disc surgery were randomly
The actions of bradykinin (BK) in Madin-Darby canine kidney (MDCK) and other cell types involve formation of arachidonic acid (AA) and AA products by as-yet-undefined mechanisms. We found that BK promoted AA release and an increase in phospholipase A2 (PLA2) activity in subsequently prepared MDCK-D1
Clots formed upon the addition of thrombin to human platelet-rich plasma (PRP) retracted readily but the clotting enzyme from Bothrops atrox venom did not cause retraction in PRP unless ADP, collagen, epinephrine, or low concentrations of thrombin (0.1 U) were added. The latter type of retraction
In this study, evidence is given that a number of isolated coupled plant mitochondria (from durum wheat, bread wheat, spelt, rye, barley, potato, and spinach) can take up externally added K(+) ions. This was observed by following mitochondrial swelling in isotonic KCl solutions and was confirmed by
The effect of resistant starch (RS) on postprandial plasma concentrations of glucose, lipids, and hormones, and on subjective satiety and palatability ratings was investigated in 10 healthy, normal-weight, young males. The test meals consisted of 50 g pregelatinized starch (0% RS) (S) or 50 g raw
The role of adenine nucleotides on vascular and platelet functions has long been established. Apyrase (CD39) takes part of a family of ecto-enzymes that hydrolyze adenosine diphosphate and adenosine triphosphate. The participation of apyrase in the thromboregulatory system is under study. An in vivo
