Opportunities for Crop Research, Development and Adoption to Drive Transformative Adaptation in Agriculture

Climate change is already affecting crop production, and in some cases is undermining the viability of current crop systems.Crop research and development plays a critical role in developing the technologies and practices farmers need to maximize productivity and manage the increasing risks they face. This paper investigates how transformative adaptation - long-term, systemic change to fundamental

Applying Climate Services to Transformative Adaptation in Agriculture

As climate change increasingly affects agriculture around the world, reliable, timely, and targeted information about weather and climate conditions is becoming an ever more urgent requirement for adaptation decision-making.This paper considers how transformative adaptation – long-term, systemic change to fundamental aspects of systems in response to or anticipation of severe climate change impact

Combinatorial gene targeting in primary human hematopoietic stem and progenitor cells

The CRISPR/Cas9 system offers enormous versatility for functional genomics but many applications have proven to be challenging in primary human cells compared to cell lines or mouse cells. Here, to establish a paradigm for multiplexed gene editing in primary human cord blood-derived hematopoietic stem and progenitor cells (HSPCs), we used co-delivery of lentiviral sgRNA vectors expressing either E

Circular RNAs to predict clinical outcome after cardiac arrest

Background: Cardiac arrest (CA) represents the third leading cause of death worldwide. Among patients resuscitated and admitted to hospital, death and severe neurological sequelae are frequent but difficult to predict. Blood biomarkers offer clinicians the potential to improve prognostication. Previous studies suggest that circulating non-coding RNAs constitute a reservoir of novel biomarkers. The

Laminar burning velocities and nitric oxide formation in premixed dimethyl ether/air flames : Experiments and kinetic modeling

Adiabatic laminar burning velocities and post-flame NO mole fractions for flat, non-stretched, premixed dimethyl ether/air flames were experimentally determined with a heat flux burner combined with laser-induced fluorescence diagnostics, over equivalence ratios ranging from 0.7 to 1.6, at atmospheric pressure and initial temperatures from 298 to 338 K. The present burning velocity measurements we

Development of a novel ex vivo model for chemical ocular toxicity assessment and its applicability for hair straightening products

This study developed an air-liquid interface (ALI) corneal model using explants bovine eyes for ocular toxicity assessment of ten chemicals and seven hair straightening mixtures. It was successfully maintained physiologically viable and normal for six days. Both eye damage (GHS cat. 1) and irritating (GHS cat. 2) chemicals induced corneal injury in our model. However, cat. 2 irritants triggered mo

Trypanocidal and cell swelling activity of 20-deoxysalinomycin

The naturally occurring polyether ionophore salinomycin was previously found to display promising anti-proliferative activity against bloodstream forms of Trypanosoma brucei. Here, we report the evaluation of 20-deoxysalinomycin, a naturally occurring homolog to salinomycin, for trypanocidal and cell swelling activity. The concentration of 20-deoxysalinomycin required to reduce the growth rate of

Chromosome-scale genome assembly of the brown anole (Anolis sagrei), an emerging model species

Rapid technological improvements are democratizing access to high quality, chromosome-scale genome assemblies. No longer the domain of only the most highly studied model organisms, now non-traditional and emerging model species can be genome-enabled using a combination of sequencing technologies and assembly software. Consequently, old ideas built on sparse sampling across the tree of life have re

Stories of paediatric palliative care : a qualitative study exploring health care professionals’ understanding of the concept

Background: By sharing patient stories, health care professionals (HCPs) may communicate their attitudes, values and beliefs about caring and treatment. Previous qualitative research has shown that HCPs usually associate paediatric palliative care (PPC) with death or dying and that they find the concept challenging to understand and difficult to implement. Attending to HCPs’ stories may provide a

Interactions in the 2×2×2 factorial randomised clinical STEPCARE trial and the potential effects on conclusions : a protocol for a simulation study

Background: Randomised clinical trials with a factorial design may assess the effects of multiple interventions in the same population. Factorial trials are carried out under the assumption that the trial interventions have no interactions on outcomes. Here, we present a protocol for a simulation study investigating the consequences of different levels of interactions between the trial interventio

Evaluating new evacuation systems related to human behaviour using a situational awareness approach – A study of the implementation of evacuation elevators in an underground facility

Elevator evacuation is associated with several safety benefits and can be a cost-efficient evacuation strategy in many buildings or facilities. Despite the advantages, elevator evacuation is not yet a common strategy in the built environment. In this paper, a design strategy that allows the designer to consider information needs of evacuees when designing the information and guidance measures for

A study comparing outcomes between obese and nonobese patients with lumbar disc herniation undergoing surgery : a study of the Swedish National Quality Registry of 9979 patients

Background: This study aimed to evaluate whether an increasing grade of obesity is associated with inferior outcomes after lumbar disc herniation (LDH) surgery. Methods: We retrieved data from the Swedish register for spine surgery regarding patients aged 20–64 who underwent LDH surgery from 2006–2016 and had preoperative and one-year postoperative data. A total of 4156 patients were normal weight

Comment on ‘Pendulum: the partial and global approach’

The paper Pendulum: the partial and global approach combines a historic introduction to the theoretical treatment of pendulum motion with presentation of data from measurements on a single pendulum. This comment focuses on the presentation and analysis of experimental data, and how the use of dimensionless variables in graphs would make use of the mathematical properties, placing the single measur

A memetic algorithm enables efficient local and global all-atom protein-protein docking with backbone and side-chain flexibility

Protein complex formation is encoded by specific interactions at the atomic scale, but the computational cost of modeling proteins at this level often requires use of simplified energy models and limited conformational flexibility. In particular, use of all-atom energy functions and backbone and side-chain flexibility results in rugged energy landscapes that are difficult to explore. In this study

Human monoclonal antibody technology. A tool to investigate human antibody repertoires.

The development of technologies to generate cell lines producing monoclonal antibodies of human origin has a great impact on the ability to study repertoires of specificities in the humoral immune response. Furthermore, it permits the generation of reagents which may be valuable for diagnostic and therapeutic applications and which lack some of the disadvantages of similar murine antibodies. In th

Communicating science through competing logics and a science-art lens

This essay takes a starting point in the well-known tension between the media logic and the scientific logic and the challenges when communicating science in a mediatized society. Building on the experience of engaging in research comics, both as a method for communicating science and a creative example of a meeting between science and art, we introduce a framework — a pedagogical tool — for how sThis essay takes a starting point in the well-known tension between the media logic and the scientific logic and the challenges when communicating science in a mediatized society.

Intra-Patient Evolution of HIV-2 Molecular Properties

Limited data are available on the pathogenesis of HIV-2, and the evolution of Env molecular properties during disease progression is not fully elucidated. We investigated the intra-patient evolution of molecular properties of HIV-2 Env regions (V1–C3) during the asymptomatic, treatment-naïve phase of the infection in 16 study participants, stratified into faster or slower progressors. Most notably

The effect of leucyl-leucine methyl ester on proliferation and Ig secretion of EBV-transformed B lymphocytes.

The selective cytotoxicity of the lysosomotropic methyl esters of leucine or its lysosomal condensation product leucyl-leucine has been used to investigate the effect of cytolytic cells on the clonal outgrowth, cellular proliferation and antibody secretion of Epstein-Barr virus (EBV)-transformed human B cells. Large granular lymphocytes (LGL), monocytes, and a subset of T cells (CD8/CD11+) were pe

Human monoclonal antibodies against a recombinant HIV envelope-antigen produced by primary in vitro immunization. Characterization and epitope mapping.

Peripheral blood lymphocytes from healthy, HIV sero-negative blood donors have been in vitro immunized using penv9, a recombinant fragment of the envelope of HIV-1. This primary in vitro immunization followed by Epstein-Barr virus (EBV) transformation and somatic cell fusion subsequently gave rise to several specific anti-penv9 monoclonal antibodies (MO28, MO30 and MO43) of μ isotype. The hybridom
