Annotation and identification of metabolite biomarkers is critical for their biological interpretation in metabolic phenotyping studies, presenting a significant bottleneck in the successful implementation of untargeted metabolomics. Here, a systematic multi-step protocol was developed for the purification and de novo structural elucidation of urin...
Polymer flocculation technology has a very broad application in the flocculation industry of oil sand tailings at present. Nevertheless, the most commonly used commercial polyacrylamide flocculant has problems of low flocculation efficiency and secondary pollution. In this paper, we proposed an organic inorganic composite flocculant with self-degra...

Introduction HIV prevalence is high among men who have sex with men (MSM) in Baltimore, Maryland, United States, and levels of viral suppression among HIV-positive MSM are relatively low. The HIV Prevention Trials Network (HPTN) 078 trial seeks to increase levels of viral suppression among US MSM by increasing rates of diagnosis and linkage to care...
BackgroundRelapse is one of the main challenges that must be tackled in the drug addiction treatment. Different factors contribute to the relapse process but it remains unclear how relapse occursin women. Describing the relapse phenomenon in women might be of interest to practitioners and academics. The aim of this study was to explore the relapse ...
The technique of Solid-Phase Extraction (SPE) is widely used in various fields to concentrate samples and the search for tools to improve recoveries remains of outmost importance. The use of polymer based cartridges has become prevailing in a broad range of fields to enrich peptides from biological matrices. However, the existing SPE protocols are ...
The data of the H alpha high-resolution spectroscopy, collected on the multiple lines of sight, which cover the entire divertor space in poloidal cross-section, during the recent hydrogen-deuterium experiments in JET-ILW (ITER-like wall), are processed. A strong spatial inhomogeneity of the hydrogen concentration, H/(H + D), in divertor is found in...
Background: In preventing the transfer of HIV to their children, the Ministry of Health in Mozambique recommends all couples follow medical advice prior to a pregnancy. However, little is known about how such women experience pregnancy, nor the values they adhere to when making childbearing decisions. This qualitative study explores perceptions and...
