Open access for operational research publications from low- and middle-income countries: who pays?
Open-access journal publications aim to ensure that new knowledge is widely disseminated and made freely accessible in a timely manner so that it can be used to improve people's health, particularly those in low- and middle-income countries. In this paper, we briefly explain the differences between closed- and open-access journals, including the evolving idea of the 'open-access spectrum'. We highlight the potential benefits of supporting open access for operational research, and discuss the conundrum and ways forward as regards who pays for open access
An apoplastic fluid extraction method for the characterization of grapevine leaves proteome and metabolome from a single sample
The analysis of complex biological systems keeps challenging
researchers. The main goal of systems biology is to decipher interactions
within cells, by integrating datasets from large scale analytical
approaches including transcriptomics, proteomics and metabolomics
andmore specialized ‘OMICS’ such as epigenomics and lipidomics. Studying
different cellular compartments allows a broader understanding of cell
dynamics. Plant apoplast, the cellular compartment external to the plasma
membrane including the cell wall, is particularly demanding to analyze.
Despite our knowledge on apoplast involvement on several processes from
cell growth to stress responses, its dynamics is still poorly known due to the
lack of efficient extraction processes adequate to each plant system.Analyzing
woody plants such as grapevine raises even more challenges. Grapevine is
among the most important fruit crops worldwide and awider characterization
of its apoplast is essential for a deeper understanding of its physiology and cellular
mechanisms. Here, we describe, for the first time, a vacuum-infiltrationcentrifugationmethod
that allows a simultaneous extraction of grapevine apoplastic
proteins and metabolites from leaves on a single sample, compatible
with high-throughput mass spectrometry analyses. The extracted apoplast
from two grapevine cultivars, Vitis vinifera cv ‘Trincadeira’ and ‘Regent’, was
directly used for proteomics and metabolomics analysis. The proteome was
analyzed by nanoLC-MS/MS and more than 700 common proteinswere identified,
with highly diverse biological functions. The metabolome profile
through FT-ICR-MS allowed the identification of 514 unique putative compounds
revealing a broad spectrum of molecular classesinfo:eu-repo/semantics/publishedVersio

INSPIRE: A European training network to foster research and training in cardiovascular safety pharmacology
Safety pharmacology is an essential part of drug development aiming to identify, evaluate and investigate undesirable pharmacodynamic properties of a drug primarily prior to clinical trials. In particular, cardiovascular adverse drug reactions (ADR) have halted many drug development programs. Safety pharmacology has successfully implemented a screening strategy to detect cardiovascular liabilities, but there is room for further refinement. In this setting, we present the INSPIRE project, a European Training Network in safety pharmacology for Early Stage Researchers (ESRs), funded by the European Commission's H2020-MSCA-ITN programme. INSPIRE has recruited 15 ESR fellows that will conduct an individual PhD-research project for a period of 36 months. INSPIRE aims to be complementary to ongoing research initiatives. With this as a goal, an inventory of collaborative research initiatives in safety pharmacology was created and the ESR projects have been designed to be complementary to this roadmap. Overall, INSPIRE aims to improve cardiovascular safety evaluation, either by investigating technological innovations or by adding mechanistic insight in emerging safety concerns, as observed in the field of cardio-oncology. Finally, in addition to its hands-on research pillar, INSPIRE will organize a number of summer schools and workshops that will be open to the wider community as well. In summary, INSPIRE aims to foster both research and training in safety pharmacology and hopes to inspire the future generation of safety scientists
Mycobacterium avium-intracellulare associated with tracheobronchopathia osteochondroplastica.
A previously healthy woman aged 53 years presented with cough, night sweats and weakness. Chest roentgenogram revealed a reticulonodular infiltrate of the right upper lung. Multiple sputum cultures were positive for Mycobacterium avium-intracellulare, with no immunodeficiency disease. Fibreoptic endoscopy showed multiple tracheal cartilaginous knobs from a tracheobronchopathia osteochondroplastica. The infiltrate improved after chest physiotherapy, but sputum cultures remained positive. Despite its low incidence, tracheobronchopathia osteochondroplastica can be associated with atypical mycobacterial disease
[Pulmonary infection due to Mycobacterium xenopi - In vitro sensitivity to classical antituberculotic drugs and clinical development]
Out of 11 patients suffering from Mycobacterium xenopi lung disease, 9 were treated with an empiric antituberculous triple chemotherapy until specific identification and antibiogram were available. Despite the important ''in vitro'' resistance to drugs, most of the patients improved; in the other patients, the impairment was always due to the underlying pathology. We conclude that the ''in vivo'' response of M. xenopi infections to antituberculous drugs is little influenced by the ''in vitro'' sensitivity
