TL;DR: In this paper, the authors analyzed both by simulations and measurements the substrate crosstalk performances of various Silicon-On-Insulator (SOI) technologies, and compared them to those of normal bulk CMOS process.
Abstract: This work analyzes both by simulations and measurements the substrate crosstalk performances of various Silicon-On-Insulator (SOI) technologies, and compares them to those of normal bulk CMOS process. The influence of various parameters, such as substrate resistivity, buried oxide thickness and distance between devices, is investigated. The use of capacitive guard rings is proposed, and their effectiveness is demonstrated. A simple RC model has been developed to allow a deep understanding of these phenomena as well as to simplify future studies of more complex systems. The superiority of high-resistivity SIMOX substrates over standard SOI and bulk is finally demonstrated.

TL;DR: Hepatic perfusion parameters measured with CT were significantly altered in cirrhosis and correlated with the severity of chronic liver disease.
Abstract: OBJECTIVE: The aim of our study was to determine if hepatic perfusion parameters measured with CT change in relation to disease severity in patients with chronic liver disease. SUBJECTS AND METHODS: Dynamic contrast-enhanced single-section CT scans of the liver were obtained in 40 individuals who included six control subjects, 16 patients with noncirrhotic chronic liver disease, and 18 patients with cirrhosis. Hepatic, aortic, and portal venous time-density curves were fitted to a dual-input one-compartment model to calculate the liver perfusion, arterial fraction, distribution volume, and mean transit time. RESULTS: Liver perfusion decreased in patients with cirrhosis (67 +/- 23 mL. min(-1). 100 mL(-1) versus 108 +/- 34 mL. min(-1). 100 mL(-1) in control subjects [p = 0.009] and 98 +/- 36 mL. min(-1). 100 mL(-1) in patients with noncirrhotic chronic liver disease [p = 0.003]), and the arterial fraction and the mean transit time increased (41 +/- 27% and 51 +/- 79 sec versus 17 +/- 16% and 16 +/- 5 sec in control subjects, and 19 +/- 6% and 17 +/- 8 sec in patients with noncirrhotic chronic liver disease [p < 0.05]). A significant correlation was seen between these three perfusion parameters and the severity of chronic liver disease based on clinical and biologic data (p < 0.001). No significant change in distribution volume was observed. CONCLUSION: Hepatic perfusion parameters measured with CT were significantly altered in cirrhosis and correlated with the severity of chronic liver disease.

TL;DR: It is found that germ-free and antibiotic-treated mice, which have severely reduced SCFA levels, have increased basal GLP-1 levels in the plasma and increased Gcg expression in the colon, and increasing these levels may be an adaptive response to insufficient energy availability in the Colon that slows intestinal transit and allows for greater nutrient absorption.
