We introduce Goslin, a polyglot grammar for common lipid shorthand nomenclatures based on the LipidMaps nomenclature and the shorthand nomenclature established by Liebisch et al. and used by LipidHome and SwissLipids. Goslin was designed to address the following pressing issues in the lipidomics field: 1) to simplify the implementation of lipid name handling for developers of mass spectrometry-based lipidomics tools; 2) to offer a tool that unifies and normalizes the main existing lipid namedoi:10.1101/2020.04.17.046656 fatcat:yonxzkbshvdnrm5qdmnvwjnr6a

We provide implementations of Goslin in four major programming languages, namely C++, Java, Python 3, and R to kick-start adoption and integration. Further, we set up a web service for users to work with Goslin directly. All implementations are available free of charge under a permissive open source license.

Highly efficient, biocompatible, and fast nucleic acid delivery methods are essential for biomedical applications and research. At present, two main strategies are used to this end. In non-viral transfection liposome- or polymer-based formulations are used to transfer cargo into cells via endocytosis, whereas viral carriers enable direct nucleic acid delivery into the cell cytoplasm. Here, we introduce a new generation of liposomes for nucleic acid delivery, which immediately fuse with thedoi:10.3390/ijms21062244 pmid:32213928 fatcat:w3awxug2ibes5cdu6wb5gd3cqe

For maximum fusion efficiency combined with high cargo transfer, nucleic acids had to be complexed and partially neutralized before incorporation into fusogenic liposomes. Among the various neutralization agents tested, small, linear, and positively charged polymers yielded the best complex properties. Systematic variation of liposomal composition and nucleic acid complexation identified surface charge as well as particle size as essential parameters for cargo-liposome interaction and subsequent fusion induction. Optimized protocols were tested for the efficient transfer of different kinds of nucleic acids like plasmid DNA, messenger RNA, and short-interfering RNA into various mammalian cells in culture and into primary tissues.
Die elektrische Stimulation des Herzens ist heute die Standardtherapie bei symptomatischen Bradykardien. Herzschrittmacher reduzieren Symptome, Synkopen und verlängern das Überleben von Hoch-Risiko-Patienten [1, 2]. Dennoch spielen insbesondere Elektroden-assoziierte Komplikationen eine bedeutsame Rolle. Eine neue Form von "elektrodenlosen" Schrittmachern könnte diese vermindern.doi:10.1055/s-0041-107413 pmid:27078248 fatcat:vgycche6gveitpxuljq4fx3upa
Despite decreasing sheath diameter, access site bleeding and vascular complications are still a major concern in transfemoral aortic valve implantation (TAVI), and may increase morbidity and even increase mortality. The aim was to compare safety of arterial closure in transfemoral TAVI with two different principles, pre-suture with ProGlide and collagen plug closure with Manta. Seventy-six patients treated with ProGlide and 75 with Manta were analysed. The endpoints were 1: access site vasculardoi:10.1186/s42155-018-0026-0 pmid:30652151 pmcid:PMC6319663 fatcat:i62tmeae5bashmtdigxhsubtba

During the learning phase there were no significant differences. In the established phase there was one event (2%) in the ProGlide group, compared to 6 endpoints (12.0%), p = 0.047, in the Manta group.Unplanned surgery or intervention was seen in two (2.7%) ProGlide and in 7 (9.3%) Manta patients, p = ns. There were no significant differences during the learning phase. In established use, endpoints occurred more frequently in patients treated with the Manta device (12%), than in patients treated with the ProGlide (2%), p = 0.047. The ProGlide presuture closure device was associated with significantly lower rates of vascular complications and lower rates of surgery and interventions compared to the collagen plug Manta system. The data were collected from Internal quality control registry on treatment of patients with valvular heart disease with or without coronary artery disease, No 2014/17280, Oslo University Hospital, Ullevål.

In the last few years high-throughput analysis methods have become state-of-the-art in the life sciences. One of the latest developments is automated greenhouse systems for high-throughput plant phenotyping. Such systems allow the non-destructive screening of plants over a period of time by means of image acquisition techniques. During such screening different images of each plant are recorded and must be analysed by applying sophisticated image analysis algorithms.

It provides the possibility to analyse colour images of plants which are taken in two different views (top view and side view) during a screening. Within the analysis different phenotypical parameters for each plant such as height, width and projected shoot area of the plants are calculated for the duration of the screening. HTPheno is applied to analyse two barley cultivars. Conclusions: HTPheno, an open source image analysis pipeline, supplies a flexible and adaptable ImageJ plugin which can be used for automated image analysis in high-throughput plant phenotyping and therefore to derive new biological insights, such as determination of fitness.

Purpose -The purpose of this paper is to address the implementation of proactive interorganizational sustainable supply chain strategies by empirically exploring the relationship between key (inter-)organizational resources of the initiating company and the establishment of widely accepted voluntary sustainability initiatives.

The authors identify capabilities that enable the creation and establishment of companydriven voluntary sustainability initiatives -namely external stakeholder integration, cross-functional integration, the management of loosely coupled business units, supply chain implementation, process improvement and cultural framing. Originality/value -With this study, the authors introduce institutional entrepreneurship theory to supply chain management literature and show that institutional entrepreneurship theory may contribute to the question of how organizations implement their interorganizational sustainable supply chain strategies. Specifically, the study derives propositions for key resources enabling the establishment of voluntary sustainability initiatives widely accepted by participants as well as initiative-external stakeholders.
The German Network for Bioinformatics Infrastructure (de.NBI) is a national and academic infrastructure funded by the German Federal Ministry of Education and Research (BMBF). The de.NBI provides (i) service, (ii) training, and (iii) cloud computing to users in life sciences research and biomedicine in Germany and Europe and (iv) fosters the cooperation of the German bioinformatics community with international network structures.

The de.NBI / ELIXIR-DE training platform, also known as special interest group 3 (SIG 3) 'Training & Education', coordinates the bioinformatics training of de.NBI and the German ELIXIR node. The network provides a high-quality, coherent, timely, and impactful training program across its eight service centers. Life scientists learn how to handle and analyze biological big data more effectively by applying tools, standards and compute services provided by de.NBI. Since 2015, more than 300 training courses were carried out with about 6,000 participants and these courses received recommendation rates of almost 90% (status as of July 2020). In addition to face-to-face training courses, online training was introduced on the de.NBI website in 2016 and guidelines for the preparation of e-learning material were established in 2018. In 2016, ELIXIR-DE joined the ELIXIR training platform. Here, the de.NBI / ELIXIR-DE training platform collaborates with ELIXIR in training activities, advertising training courses via TeSS and discussions on the exchange of data for training events essential for quality assessment on both the technical and administrative levels. The de.NBI training program trained thousands of scientists from Germany and beyond in many different areas of bioinformatics.
