urea breath testBackground: Different types of Helicobacter pylori (H. pylori) were analyzed to determine their infection characteristics using serology, pathology, and nonmagnification white light endoscopy combined with the Kimura–Takemoto classification, and the regular arrangement of ...
(2) it was also found that abrupt changes of different levels of precipitation displayed difference atthe 0.05 level, the change of light rain was especially remarkable;(3) the results indicated that the spatialdistributions of precipitation of different grades changed from east to west and from ...
Urease (EC 3.5.1.5), a dinickel enzyme, catalyses the hydrolysis of urea to carbonic acid (H2CO3) and ammonia (NH3) via the formation of carbamic acid (H2NCOOH) (Fig.1)1. In aqueous solutions, the carbonic acid and NH3are in equilibrium with bicarbonate (HCO3−) and ammonium (NH4+...
(bloodstream) with all the prepared biosensor. This research features a feature that sheds light on biosensor studies becoming created when it comes to recognition of substances within your body, such as sugar, uric-acid, and urea. This article will set an illustration for future scientific study...
Different grades of graphite were used as adsorbents for fluoride removal from water [93]. At appreciable extent, competing anions did not affect fluoride removal. Carbons loaded with specific chemical moieties were prepared from pecan nut shells employing a natural modifier agent obtained from egg ...
Changes in land use have an impact on ecosystem services by affecting soil quality. Thus, soil quality assessment using the soil quality index (SQI) can he
and Al(III) in the pH conditions of their occurrence. The paper presents the possible types of transformation of aluminum hydroxyl forms and aluminum sulfate complexes by the reaction of the sample with mobile phase. An indirect method for the determination of aluminum in the form of aluminum ...
Isolates from this microbe cluster by molecular analysis into two major genotypic groups or ecotypes, one found in temperate latitudes in the upper water column and another that is for the most part found in the deep water column of the Mediterranean. Here, we describe the genome of one ...
Nowadays, among the different types of materials, Au has innumerable properties when it is reduced to nanometric dimensions, in particular: Their small size increases the number of surface atoms compared to the number of those in the volume. This happens because as the size decreases, there is...
Both types of belts were produced by continuous extrusion [5] into a semi-finished product of substantial length and then wound onto reels. Therefore, it is possible to hypothesize that the circular belt and the flat belt have the same thermomechanical properties, which in turn enables their ...
