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 ...

Microbial induced carbonate precipitation (MICP) through the ureolysis metabolic pathway is one of the most studied topics in biocementation due to its high efficiency. Although excellent outcomes ...

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 ...

Calcium carbonate precipitation and crystallization induced by urease enzyme to solidify soil is known as biocement technology. The uses of waste and cheap materials can make this technology more cost ...

Self-propelling micro- and nano-motors (MNMs) have been extensively investigated as an emerging oral drug delivery carrier for gastrointestinal (GI) tract diseases. However, the propulsion of current ...

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 ...
