Facilitating Imaging Mass Spectrometry of Microbial Specialized Metabolites with METASPACE.

Metabolite annotation from imaging mass spectrometry (imaging MS) data is a difficult undertaking that is extremely resource intensive. Here, we adapted METASPACE, cloud software for imaging MS metabolite annotation and data interpretation, to quickly annotate microbial specialized metabolites from high-resolution and high-mass accuracy imaging MS data. Compared with manual ion image and MS1 annotation, METASPACE is faster and, with the appropriate database, more accurate.

A Long-Distance RF-Powered Sensor Node with Adaptive Power Management for IoT Applications.

We present a self-sustained battery-less multi-sensor platform with RF harvesting capability down to -17 dBm and implementing a standard DASH7 wireless communication interface. The node operates at distances up to 17 m from a 2 W UHF carrier. RF power transfer allows operation when common energy scavenging sources (e.

[Laparoscopic cholecystectomy in the day surgery setting].

The first laparoscopic cholecystectomy in the Department of Surgery of the S. Giacomo Hospital in Rome was performed in April 1991. At that time, for the complete study of the patient and recovery from the operation, a mean period of five days was necessary.

[Therapy of asymptomatic gallstones: indications and limits].

Gallstone disease is one of the most common health problems world-wide. It is also one of the main causes of medical expenditure in Western countries. Asymptomatic gallstones are defined as stones that have not given rise to biliary cholic or other biliary symptoms.
