Helicobacter pylori (H.pylori) is the most prominent causative agent of gastroduodenal diseases all over the world. Other manifestations such as urticaria and coronary heart diseases, also are suspected to be induced by H.pylori. Non invasive methods are preferred for diagnosis and ELISA, because of its reliability, speed, sensitivity and specificity is widely preferred as diagnostic tool. Prev...
Our lack of total understanding of the intricacies of how enzymes behave has constrained our ability to robustly engineer substrate specificity. Furthermore, the mechanisms of natural evolution leading to improved or novel substrate specificities are not wholly defined. Here we generate near-comprehensive single-mutation fitness landscapes comprising >96.3% of all possible single nonsynonymous ...
Time-resolved sum-frequency generation is an established tool to investigate ultrafast vibrational dynamics with surface and interface specificity. We present an extension of the technique to the regime of electronic transitions based on a compressed white light continuum. It is used to probe the non-equilibrium dynamics of excitonic resonances in the non-centrosymmetric oxide ZnO, where we dem...
Background: We designed an algorithmic model based on the logistic regression analysis and a non-algorithmic model based on the Artificial Neural Network (ANN). Materials and methods: The ability of these models was compared together in clinical application to differentiate malignant from benign breast tumors in a study group of 161 patients' records. Each patient’s record consisted of 6 subjec...
