This work is investigating functional, histopathological, and molecular changes underlying Helicobacter pylori hypomotility and is correlating these with miR-1, whose disturbance is supposed to be involved in smooth muscle dysfunction and cell proliferation according to literature. Epithelial to mesenchymal transition and reduced ghrelin hormone may contribute to H. pylori infection-associated hypomotility. H. pylori infection was associated with reduced pyloric miR-1 expression. Targeting miR-1 could be valuable in the clinical management of pyloric hypofunction.

This paper proposes a new optimization methodology for RF-to-DC converters. The proposed methodology optimizes the power conversion efficiency (PCE) at low RF input power. In addition, it improves the sensitivity and extends the dynamic range. An LC-circuit is embedded with any RF-to-DC converter circuit architecture. Since it reduces the matching constraints at different frequency bands and boosts up the low RF input power. The proposed methodology is applied to four different circuit topologies where the performance results are improved significantly compared to the original architectures. All designs are simulated and verified at dual frequency bands (1.9GHz and 2.4 GHz) with fixed load impedance $50K\Omega$ . Finally, a prototype is implemented using two different CMOS technology nodes (130nm and 65nm) to emphasize the technology process effect on the circuit nerformance.
