J. Mickley‚ and Manuel T. Lerdau (2010) believe that the spread of Kudzu has the potential to raise ozone levels (this would be bad) by the emission of nitric oxide. Hickman and company created a study that observed the effect of kudzu on trace gas emissions in three different places in Georgia. Their study concluded that emissions of nitric oxide in the soils containing Kudzu were over 100% higher than the soil without Kudzu growing in it. According to the model created by Hickman et al. “Our model

The liver is a vital organ within the human body. The normal pathophysiology of the liver is to perform critical functions which rid the body of harmful toxins and substances. The liver rids the body of its harmful toxins by the way it secretes chemicals and produces bile. Bile is a substance that helps the breakdown of lipids and salts so that they are easily absorbed into the intestine to be secreted out of the body. Vasodilators are medications which cause the blood vessels within the human body

Long Island University Riociguat (Adempas‚Bayer) Therapeutic class: Cardiovascular Agent‚ Soluble Guanylate Cyclase Stimulators Clinical Pharmacology: Sensitizes soluble guanylate cyclase (sGC) to endogenous nitric oxide (NO) by stabilizing the NO-sGC binding. It also directly stimulates sGC independent of NO. Riociguat stimulates the NO-sGC–cyclic guanosine monophosphate (cGMP) pathway and leads to increased generation of cGMP with subsequent vasodilation Pharmacokinetics: Absorption:
