A positive test for nitrites in the urine is called nitrituria. This test is commonly used in diagnosing urinary tract infections (UTIs). A positive nitrite test indicates that the cause of the UTI is a Gram-negative organism, most commonly Escherichia coli. The reason for nitrites' existence in the presence of a UTI is due to a bacterial ...
Bacteriuria is the presence of bacteria in urine. [1] Bacteriuria accompanied by symptoms is a urinary tract infection while that without is known as asymptomatic bacteriuria. [1][2] Diagnosis is by urinalysis or urine culture. [3] Escherichia coli is the most common bacterium found. [1] People without symptoms should generally not be tested ...
In medicine, exhaled nitric oxide (eNO) can be measured in a breath test for asthma and other respiratory conditions characterized by airway inflammation. Nitric oxide (NO) is a gaseous molecule produced by certain cell types in an inflammatory response. The fraction of exhaled NO (FE NO) is a promising biomarker for the diagnosis, follow-up ...
The Griess test is an analytical chemistry test which detects the presence of nitrite ion in solution. One of its most important uses is the determination of nitrite in drinking water. The Griess diazotization reaction, on which the Griess reagent relies, was first described in 1858 by Peter Griess. [1][2] The test has also been widely used for ...

A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
Luckily, home inspectors have a keen-scented ally in their battle against mold infestations: mold detection dogs. Watch as Xia, a professional canine mold detector working for a mold inspection ...
Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood.
