Introduction: Helicobacter pylori is a gram-negative bacillus responsible for numerous gastroduodenal pathologies, and this infection public health problem. The prevalence of with bacterium remains high in countries limited resources. Diagnosis relies mainly on invasive noninvasive methods. aim work was to evaluate the different indirect diagnostic methods using bacterial cultures. Methods: We ...

Nowadays, web designers are forced to have an even deeper perception of how users approach their products in terms user experience and usability. Remote Usability Testing (RUT) is the most appropriate tool assess usability platforms by measuring level attention, satisfaction, productivity. RUT does not require physical presence evaluators, but for this very reason makes data collection more dif...

Several acridone alkaloids have been isolated from roots of Ruta graveolens (for summary see [1, 2]). One of the main alkaloids is rutacridone (1) which seems to be a precursor of several derivatives with hydroxyl or chlorine functions at the isopropyl moiety. As an intermediate an 18,19-epoxide of rutacridone could be postulated [1, 3] that has not yet been identified. Screening for antimicrob...

This data gives an opportunity to confi rm to some extent the degree to which these strategies are used. More importantly, perhaps, while articles on the best and worst strategies for choosing passcodes are not in short supply, the data gives us a better starting point for evaluating the entropic effi cacy of these strategies as the basis for better recommendations to end-users. And that’s a to...

We develop a new transformation theory in quantum physics, where the transformation operators, defined in the infinite dimensional Hilbert space, have right-unitary inverses only. Through several theorems, we discuss the properties of state space of such operators. As one application of the right-unitary transformation (RUT), we show that using the RUT method, we can solve exactly various inter...

How is pictorial relief represented in visual awareness? Certainly not as a "depth map," but perhaps as a map of local surface attitudes (Koenderink & van Doorn, 1995). Here we consider the possibility that observers might instead, or concurrently, represent local surface shape, a geometrical invariant with respect to motions. Observers judge local surface shape, in a picture of a piece of scul...

Helicobacter pylori, an important etiological agent in the development of gastritis, peptic ulcer and gastric carcinoma, can be detected by the enzyme-linked immunosorbent assay (ELISA). Our objectives were: (1) to evaluate the efficacy of a commercial ELISA kit (Pyloriset EIA-G III) in sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for ...

Among the methods developed to detect H. pylori infection, determining the gold standard remains debatable, especially for epidemiological studies. Due to the decreasing sensitivity of direct diagnostic tests (histopathology and/or immunohistochemistry [IHC], rapid urease test [RUT], and culture), several indirect tests, including antibody-based tests (serology and urine test), urea breath test...

Mushroom body (MB)-dependent olfactory learning in Drosophila provides a powerful model to investigate memory mechanisms. MBs integrate olfactory conditioned stimulus (CS) inputs with neuromodulatory reinforcement (unconditioned stimuli, US), which for aversive learning is thought to rely on dopaminergic (DA) signaling to DopR, a D1-like dopamine receptor expressed in MBs. A wealth of evidence ...
