Abstract: A dual- zoned, three-dimensional, resilient absorbent web is disclosed which is suitable as body-side liner for absorbent articles such as feminine pads, diapers and the like. When used as a liner in absorbent articles, the dual-zoned web combines the advantages of apertured films and soft, nonwoven cover layers in one structure while still being inherently hydrophilic. The liner comprises a web of wet-resilient, hydrophilic basesheet having a three-dimensional topography comprising elevated regions onto which hydrophobic matter is deposited or printed and a plurality of spaced apart depressed regions. In a preferred embodiment, the hydrophobic matter applied to the elevated regions of the basesheet comprises hydrophobic fibers in a contiguous nonwoven web which has been apertured or provided with slits or other openings, such that the apertures or openings overlay a portion of the depressed regions. The elevated hydrophobic regions enhance dry feel and promote fluid flow toward the lower hydrophilic regions, which comprise the exposed depressed regions of the basesheet. The basesheet is preferably in liquid communication with underlying absorbent material, most preferably a stabilized airlaid cellulosic material or compressed stabilized fluff such that the absorbent material can wick fluid out of the basesheet by capillary action. When soft, hydrophobic fibers are deposited on the elevated regions, the liner also has a soft, cloth-like feel in addition to a dry feel in use.

Abstract: PURPOSE: Provided is a composition containing low concentration of 13C-labeled urea useful for analysing the infection of Helicobacter pylori, thereby the infection of Helicobacter pylori can be exactly and cheaply diagnosed. CONSTITUTION: The composition contains 13C-labeled urea in an amount of 90% or less, preferably from 10 to 90%, and more preferably from 25% to 75%, and is usually administered orally into a patient suffering from the infection of Helicobacter pylori. When a person who orally administers the composition containing 13C-labeled urea is infected with Helicobacter pylori, urea is hydrolyzed by urease produced from Helicobacter pylori to produce 13CO2 and the ratio of 13CO2/12CO2 is increased. The infection of Helicobacter pylori is determined by calculating the ratio of 13CO2/12CO2 using the mathematical equation 2 described as in the description.
