The (13)C-urea breath test ((13)C-UBT), developed a few decades ago, is widely used as a non-invasive diagnostic method to detect only the presence of the gastric pathogen Helicobacter pylori infection; however, the actual disease state, i.e. whether the person harbouring H. pylori has peptic ulcer disease (PUD) or non-ulcerous dyspepsia (NUD), is still poorly understood. Nevertheless, the present (13)C-UBT has numerous limitations, drawbacks and pitfalls owing to the ingestion of (13)C-labelled external urea...

Ionic liquids (ILs) were considered as "green" solvents and have been used widely because of their excellent properties. But ILs are not as "green" as has been suggested, and the toxic effects of ILs on organisms have been shown in recent years. In the present study, the toxic effects of the IL 1-octyl-3-methylimidazolium tetrafluoroborate ([Omim]BF4) on soil enzyme activity and soil microbial communities at three different concentrations (1.0, 5.0 and 10.0mg/kg) and a control treatment over 40 days of incubation time (sampled on days 10, 20, 30 and 40) were examined under laboratory conditions...

Urinary tract infections (UTIs) pose a threat especially to women, the individuals with weakened immunity or with abnormalities in the urinary tract as well as to hospitalized and catheterized patients. The bacteria from the genus Proteus, especially P. mirabilis, are important UTI pathogenic factors. They frequently cause chronic, recurrent or severely complicated infections, resulting in the urinary stones production due to urease and other virulence factors. The ability to survive inside the stones and the increasing antibiotic resistance make it difficult to eradicate the bacteria from the urinary tract...
