Indeed, research conducted since the mid-1980s has shown that the bacterium Helicobacter pylori(H. pylori) is present in more than 90% of duodenal ulcers and about 80% of stomach ulcers. However, more recent figures indicate those percentages are declining.

In previous issues, we explained the purpose of yield curves and looked at different yield measurements â the main ones being yield to maturity (YTM) and current yield. This month we explore different bases for yield curves. There are a number of different bases on which to construct the graph of a yield curve. The four main ones are yield, forward rate, par yield and zero coupon yield. These use different bond profiles to construct the expected term structure from which the yield curve is drawn.
