Application of a urine and hair validated LC-MS/MS method to determine the effect of hair colour on the incorporation of 25B-NBOMe, 25C-NBOMe and 25I-NBOMe into hair in the rat.

NBOMes are a group of new psychoactive substances derived from phenethylamines. Recreational abuse is thought to have begun in 2010 and they are commonly associated with the “club drug” scene. They are administered in liquid form or as blotters due to their high potency. An LC-MS/MS method was validated using SWGTOX parameters for the detection of 25B-, 25C- and 25I-NBOMe using 25B-NBOMe-D3 as internal standard for urine and hair. Calibration graphs with R2 values >0.99 were observed for urine and hair for concentrations ranging from 0.1 -100 ng/mL and 0.025-2.5 ng/mg respectively. Urine LODs ranged from 5-25 pg/mL and had an LOQ of 50 pg/mL. Hair LOD and LOQs ranged from 3-5 pg/mg and 6.25-12.5 pg/mg respectively. Intra and inter-day precision was <20% and accuracy was within ± 20% for both matrices. The method was shown to be selective for both exogenous and endogenous compounds. No matrix effects were observed for either matrix. LLE recovery ranged from 90-103% for urine samples and SPE recovery ranged from 80-107% for hair samples. Long-Evans rats (n=55) were administered 25B-, 25C- or 25I-NBOMe at doses ranging from 30-300 µg/kg over a period of 10 days. Rats were shaved prior to their first dose and re-shaved after the 10-day period. Hair was separated by colour (black: n=55 and white: n=55) and analysed using the validated LC-MS/MS method to assess the impact hair colour has on the incorporation of these drugs. All drugs were successfully detected in black hair. 25B-NBOMe from rats receiving the highest dose and 25C-NBOMe from rats receiving the medium and high doses were quantified in white hair. 25I-NBOMe was detected but fell below the limit of quantification. A dose-dependent concentration increase was observed in the black hair. All pooled urine samples tested positive for their expected NBOMes

Expanding Qualitative Research Interviewing Strategies: Zoom Video Communications

The proliferation of new video conferencing tools offers unique data generation opportunities for qualitative researchers. While in-person interviews were the mainstay of data generation in qualitative studies, video conferencing programs, such as Zoom Video Communications Inc. (Zoom), provide researchers with a cost-effective and convenient alternative to in-person interviews. The uses and advantages of face-to-face interviewing are well documented; however, utilizing video conferencing as a method of data generation has not been well examined. The purpose of this paper is to examine the specific attributes of Zoom that contribute to high quality and in-depth qualitative interviews when in person interviewing is not feasible. While video conferencing was developed to facilitate long-distance or international communication, enhance collaborations and reduce travel costs for business these same features can be extended to qualitative research interviews. Overall, participants reported that Zoom video conferencing was a positive experience. They identified strengths of this approach such as: (1) convenience and ease of use, (2) enhanced personal interface to discuss personal topics (e.g., parenting), (3) accessibility (i.e., phone, tablet, and computer), (4) time-saving with no travel requirements to participate in the research and therefore more time available for their family. Video conferencing software economically supports research aimed at large numbers of participants and diverse and geographically dispersed populations

Community service providers' roles in supporting communication disability rehabilitation in Majority World contexts: An example from Ghana

Purpose: In Majority World countries, where speech-language pathology services are extremely limited, people with communication disabilities (PWCD) may seek help from a range of service providers. This qualitative research aimed to explore the nature of community services offered to people with communication disabilities who seek help in Accra, Ghana. Method: Semi-structured interviews were conducted with nine individuals from three professions: pastors (3), doctors (3), and herbalists (3) exploring services that they may offer to PWCD seeking help. Interviews were analysed using Thematic Network Analysis. Result: Six global themes described beliefs about communication disability, types of intervention, explanations provided to people with communication disabilities, promoting communication, processes for selecting treatments, and links between service providers. Interventions encompassed physical, spiritual, psychosocial and environmental approaches, with the notion of plural beliefs interwoven through a number of themes. Conclusion: In Ghana, and other Majority World contexts, service providers in sectors not commonly associated with communication disability rehabilitation may have important roles to play in supporting people with communication disabilities. Understanding the contributions of other service providers may assist the growing profession of speech-language pathology to collaborate across sectors, to develop specific, culturally responsive approaches to service development

Mothers of Soldiers in Wartime: A National News Narrative

National news media represent mothers of US combat soldiers in the Iraq War as archetypal good mothers, that is, mothers who continue their maternal work even after their children are deployed. However, not all mothers are depicted as the archetypal patriotic mother, i.e., a good mother who is also stoic and silent about the war and her child\u27s role in it. Mothers of soldiers are portrayed as good mothers who sometimes also voice their attitudes about the war effort. The maternal attitudes ranged from complete support for the war to opposition to the war but support for the soldiers. The findings suggest a picture of wartime motherhood that is more nuanced than the historical image of the patriotic mother suggests

EIFiso4G augments the synthesis of specific plant proteins involved in normal chloroplast function

Copyright © 2019 American Society of Plant Biologists. All rights reserved. The plant-specific translation initiation complex eIFiso4F is encoded by three genes in Arabidopsis (Arabidopsis thaliana)-genes encoding the cap binding protein eIFiso4E (eifiso4e) and two isoforms of the large subunit scaffolding protein eIFiso4G (i4g1 and i4g2). To quantitate phenotypic changes, a phenomics platform was used to grow wild-type and mutant plants (i4g1, i4g2, i4e, i4g1 × i4g2, and i4g1 × i4g2 × i4e [i4f]) under various light conditions. Mutants lacking both eIFiso4G isoforms showed the most obvious phenotypic differences from the wild type. Two-dimensional differential gel electrophoresis and mass spectrometry were used to identify changes in protein levels in plants lacking eIFiso4G. Four of the proteins identified as measurably decreased and validated by immunoblot analysis were two light harvesting complex binding proteins 1 and 3, Rubisco activase, and carbonic anhydrase. The observed decreased levels for these proteins were not the direct result of decreased transcription or protein instability. Chlorophyll fluorescence induction experiments indicated altered quinone reduction kinetics for the double and triple mutant plants with significant differences observed for absorbance, trapping, and electron transport. Transmission electron microscopy analysis of the chloroplasts in mutant plants showed impaired grana stacking and increased accumulation of starch granules consistent with some chloroplast proteins being decreased. Rescue of the i4g1 × i4g2 plant growth phenotype and increased expression of the validated proteins to wild-type levels was obtained by overexpression of eIFiso4G1. These data suggest a direct and specialized role for eIFiso4G in the synthesis of a subset of plant proteins

Stitching a new garment: considering the future of the speech–language therapy profession globally

Providing equitable support for people experiencing communication disability (CD) globally is a historical and contemporary challenge for the speech–language therapy profession. A group of speech–language therapists (SLTs) with ongoing and sustained experiences in Majority and Minority World contexts participated in five virtual meetings in 2021. The aim of these meetings was to develop provocative statements that might spur a global discussion among individuals and organisations that support people experiencing CD. The following questions were discussed: What is our vision for the future of the profession globally? What are the global challenges around access to speech–language therapy services? Four main themes emerged: (1) the need to centre people experiencing CD as the focal point of services, (2) participation, (3) equity and (4) community. The themes relate to the need for a process of de-imperialism in the profession. Suggestions were made to develop more suitable terminology and to establish a global framework that promotes more equitable access to communication services. We seek the adoption of approaches that focus on reciprocal global engagement for capacity strengthening. Alternative models of culturally sustaining and equitable service delivery are needed to create impact for people experiencing CD, and their families worldwide. Contribution: Provocative statements were developed to prompt global conversations among speech–language therapy professionals and associations. We encourage readers to consider the questions posed, share their viewpoints and initiate positive change towards a global strategy
