Effect of different pooled qc samples on data quality during an inter-batch experiment in untargeted UHPLC-HRMS analysis on two different MS platforms.

Quality control (QC) samples are commonly used in metabolomics approaches for three main reasons: (i) the initial conditioning of the column; (ii) the correction of analytical drift especially between batches; and (iii) the evaluation of measurement precision. In practice, there are several ways to prepare and conserve QC samples. The most common in untargeted metabolomics is to pool samples after or before extraction, in order to obtain pooled QC samples accounting, respectively, for analytical variance or for both analytical and sample preparation variances.

Grapevine response to a extract and a strain.

The present study aims to evaluate the response of the three Mediterranean local grapevines 'Garnacha Blanca', 'Garnacha Tinta', and 'Macabeo' to treatments with biocontrol products, namely a botanical extract (Akivi, extract) and a beneficial microorganism ( UdG, ). A combination of transcriptomics and metabolomics approaches were chosen in order to study grapevine gene expression and to identify gene marker candidates, as well as, to determine differentially concentrated grapevine metabolites in response to biocontrol product treatments. Grapevine plants were cultivated in greenhouse under controlled conditions and submitted to the treatments.

Untargeted metabolomics as a tool to monitor biocontrol product residues' fate on field-treated Prunus persica.

Evidence of chemical plant protection products' (PPPs) long-term impact has been found in all environmental compartments. Therefore, other types of PPPs are developed to complement chemical PPPs like PPPs from natural sources, namely biocontrol products (BPs). Little is known about those new BPs, and it is important to assess their potential long-term environmental impact.

Intraoperative blood salvage in proximal femur epiphysiolysis surgical treatment with hip controlled dislocation technique: a case series study.

Objectives: To report a case series of Intraoperative Blood Salvage (IOS) in surgeries during the treatment for Slipped Capital Femoral Epiphysis (SCFE) with controlled dislocation of the hip, identifying its efficacy, complications, and the profile of patients with SCFE.

Methods: Descriptive study reporting a case series, comprising patients seen between January 2016 and March 2018, diagnosed with SCFE, and treated with controlled surgical dislocation of the hip using IOS.

Results: Sample comprised of 15 patients, with a mean age of 13.
