My unsuspecting German shepherd mix, Daisy, helped me test out four different dog DNA kits to find the best one. All instructions were followed closely, with the exception of required swabbing times.
Rapid urease test, also known as the CLO test (Campylobacter-like organism test), is a rapid diagnostic test for diagnosis of Helicobacter pylori. [1] The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and carbon dioxide .
In Sporosarcina pasteurii urease, the flap was found in the open conformation, while its closed conformation is apparently needed for the reaction. [15] When compared, the α subunits of Helicobacter pylori urease and other bacterial ureases align with the jack bean ureases. [16] The binding of urea to the active site of urease has not been ...
Adam Boyko was part of a team of scientists who in 2015 discovered that the origin of domestic dogs was near Central Asia 15,000 years ago. [19] In 2016, he was the senior author of a study by Cornell College of Veterinary Medicine researchers that was the largest genetic study of dogs to ever be completed, with a collection of samples that ...
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
Phenol in the Berthelot reagent can be replaced by a variety of phenolic reagents, the most common being sodium salicylate, which is significantly less toxic. [1] This has been used for blood urea nitrogen (BUN) determinations and commonly is used to determine water and soil total and ammonia-N. Replacement of phenol by 2-phenylphenol reduces interferences by a variety of soil and water ...
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

Surface residues, such as thatch and plant stubble exhibit increased urease activity. Soils that have high organic matter content also tend to have higher urease concentrations. More urease results in greater hydrolysis of urea and ammonia volatilization, particularly if urea fails to move into the soil. [8]
