A hydrogen and a hydroxide ion can also join together to form a water molecule. In pure water, hydrogen and hydroxide ions are present in a 1:1 ratio since the only source of these ions is the ionization of water. Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. In this lesson, we will first explore the chemistry of acids and bases, then we will show how to calculate their concentration mathematically.
Methylprednisolone is a steroid, so while under treatment with it, you may experience blood pressure elevations and elevated heart rate. Other side effects, as listed by the FDA,... Comment Helpful?
In the present study, we sought to determine how the heart rate of D. magna was. affected by two previously untested compounds: curcumin and diphenhydramine (DPHM). DPHM produces a number of cardiotoxic side effects in vertebrates, particularly sinus. tachycardia. Curcumin acts as a monoamine oxidase inhibitor (MAOI) and was expected to. increase the heart rate of D. magna. DPHM was found unexpectedly to lower the heart rate of D. magna with time. Curcumin increased heart rate when administered in higher concentrations.
