Biosolids as a Source of Antibiotic Resistance Plasmids for Commensal and Pathogenic Bacteria.

Antibiotic resistance (AR) is a threat to modern medicine, and plasmids are driving the global spread of AR by horizontal gene transfer across microbiomes and environments. Determining the mobile resistome responsible for this spread of AR among environments is essential in our efforts to attenuate the current crisis. Biosolids are a wastewater treatment plant (WWTP) byproduct used globally as fertilizer in agriculture.

Rapid eye movement sleep behavior disorder or epileptic seizure during sleep? A video analysis of motor events.

Purpose: To compare the motor semiology of sleep behavior disorder (RBD) during rapid eye movement (REM) with epileptic seizures in non-REM and REM sleep.

Methods: We analyzed the types and frequency of motor events from videos of patients with RBD (n = 15, mean age 64.8 years, 179 motor episodes) and patients with epilepsy (n = 15, mean age 34.

4h versus 1h-nap-video-EEG monitoring in an Epileptology Unit.

Objective: To compare the performance of 4h-video EEG monitoring (VEEG) and 1h-nap-VEEG in an Epileptology Unit.

Methods: We examined short-term VEEG data from 196 patients admitted to characterize their: (i) clinical events; (ii) epileptic syndromes or (iii) state after status epilepticus or surgery. We compared the 4h-VEEG and 1h-nap-VEEG performances using three measures: (i) the capability to detect epileptic seizures (ES), psychogenic non-epileptic seizures (PNES), interictal epileptiform abnormalities (IEA) and sleep-related IEA; (ii) the usefulness to answer questions on referral; (iii) the sensitivity for the final diagnosis.

Evaluation of capillary zone electrophoresis for charge heterogeneity testing of monoclonal antibodies.

Within pharmaceutical industry charge heterogeneity testing of biopharmaceuticals has to be reproducible and fast. It should pass method validation according to ICH Q2. Classical approaches for the analysis of the charge heterogeneity of biopharmaceuticals are ion exchange chromatography (IEC) and isoelectric focusing (IEF).
