What is Helicobacter pylori (H. pylori)? Helicobacter pylori (H. pylori) is a type of bacteria that infects your stomach. It can damage the tissue in your stomach and the first part of your small ...

Kidney stones are one of the most painful medical conditions a person can experience. For people who suffer from recurring stones, the agony is even worse. Standard oral medications often take too ...

The urea breath test is used to detect Helicobacter pylori (H. pylori), a type of bacteria that may infect the stomach and is a main cause of ulcers in both the stomach and duodenum (the first part of ...

The most common method of measuring urease activity is to add a colorimetric assay agent for ammonia (e.g., Nessler’s reagent) to a solution of hydrolyzed urea. The absorbance of the solution at a ...

Preparation for the breath test involves abstaining from certain medications for several weeks and fasting food and water a few hours before the test. The test is safe during pregnancy and for ...

Quantifying urease activity is an important task for Microbial Induced Calcite Precipitation research. A new urease activity microplate assay using a fluorescent pH indicator is presented. The method ...

Helicobacter pylori is commonly associated with gastric ulcer. The bacteria are showing resistance to common antibiotics. Natural antimicrobial such as Clove oil, curcumin showed significant ...

In the rumen of cattle, urease produced by ureolytic bacteria catalyzes the hydrolysis of urea to ammonia, which plays an important role in nitrogen metabolism and animal production. A high diversity ...

Our work provides insights into how cells solve the problem of delivering nickel, a toxic metal, to the active site of a metalloenzyme such as urease. Urease, a nickel-containing enzyme, is a ...

Urease, a nickel-containing metalloenzyme, was the first enzyme to be crystallized and has a prominent position in the history of biochemistry. In the present study, we identified a nickel urease gene ...
