1997. Does availability of potassium affect cold hard- ening of Scots pine through polyamine metabolism. Physiologia Plantarum 99: 56-62.SARJALA, T., K. TAULAVUORI, E.-M. SAVONEN, and A.-B. EoFAST: Does availability of potassium affect cold hardening of Scots pine through polyamine ...
Regulation of muscle contractions including the heart: The nervous system to controls the muscle contractions. Nerve signals are generated when sodium enters the cells while potassium exit the cells. Both low andhigh potassiumlevels can affect nerve signals creating irregular heart rhythm (arrhythmia) t...
Why does potassium weaken cardiac contractions? Acetylcholine acts on the heart by: a. blocking the action of calcium. b. causing an increase in the stroke volume. c. decreasing heart rate. d. increasing heart contractility. In heart rate, what happens if the calcium level is high or low?
he first part of the experiment, exercise 1, dealing with heart rate and temperature can be seen in Table 1. It was apparent that temperature decreased the heart rate and this was probably due to same principles surrounding nerves. If the temperature is too low it is harder for ions to pa...
It’s a vegetable used in Asia, South America, India, and parts of Africa. It looks and tastes a little like a cucumber, but is very bitter. It’s rich invitaminsA, C, and beta-carotene and minerals like iron andpotassium. Traditional medicine uses the fruit and seeds to treat many ...
There were no abnormalities found among the patients in ion concentrations such as potassium, sodium, and chlorine in peri-operation, and the blood volume of each patient was in the normal range, hence it can be assumed that the total blood volume would be the same on who...
Human iPSC-derived engineered heart tissue (hEHT) has been used to remuscularize injured hearts in a guinea pig infarction model. While beneficial effects on cardiac remodeling have been demonstrated, the arrhythmogenic potential of hEHTs is a major concern. We investigated whether hiPSC-derived hE...
Abdominal aortas were dissected, rinsed once with sterile phosphate-buffered saline (PBS, 137 mM sodium chloride, 10 mM phosphate, 2.7 mM potassium chloride) pH 7.4, and frozen until RNA extraction. The abdominal aorta was used for quantitative polymerase chain reaction (PCR) analyses. Immediately...
Dose-response curves to NE (100 nmol–10 mmol/L) and potassium chloride (KCl, 20–100 mmol/L) were completed to assess receptor-mediated and nonreceptor-mediated vasoconstriction, respectively. In aortae, basal nitric oxide synthase activity was estimated by adding NG monomethyl-L-arginine (L-...
