Demarcating the dirty work: Canadian Fertility professionals' use of boundary-work in contentious egg donation.

Authors:
Skye A Miner

Soc Sci Med 2018 Dec 1;221:19-26. Epub 2018 Dec 1.

Department of Sociology, McGill University, Room 712, Leacock Building, 855 Sherbrooke Street West, Montreal, QC, H3A 2T7, Canada. Electronic address:

The potential medical risks to egg donors, in addition to the concern over the commodification of life, has led to debates surrounding the ethics of paying donors. In Canada, payment for eggs is prohibited by law; however, what is considered payment is contentious and has yet to be defined. The lack of legislative clarity coupled with increased ethical concerns over paying a donor has shifted egg donation from a medically-controlled procedure to a legal and social endeavor involving multiple professionals.

Eukaryotic Initiation Factor 5B (eIF5B) Cooperates with eIF1A and eIF5 to Facilitate uORF2-Mediated Repression of ATF4 Translation.

Int J Mol Sci 2018 Dec 13;19(12). Epub 2018 Dec 13.

Department of Chemistry and Biochemistry, University of Lethbridge, 4401 University Drive W, Lethbridge, AB T1K 3M4, Canada.

A variety of cellular stresses lead to global translation attenuation due to phosphorylation of the alpha subunit of eukaryotic initiation factor 2 (eIF2), which decreases the availability of the eIF2-GTP-Met-tRNA ternary complex. However, a subset of mRNAs continues to be translated by non-canonical mechanisms under these conditions. In fact, although translation initiation of activating transcription factor 4 (ATF4) is normally repressed by an upstream open reading frame (uORF), a decreased availability of ternary complex leads to increased translation of the main ATF4-coding ORF.

What We Already Know About This Topic: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Although dantrolene effectively treats malignant hyperthermia (MH), discrepant recommendations exist concerning dantrolene availability. Whereas Malignant Hyperthermia Association of the United States guidelines state dantrolene must be available within 10 min of the decision to treat MH wherever volatile anesthetics or succinylcholine are administered, a Society for Ambulatory Anesthesia protocol permits Class B ambulatory facilities to stock succinylcholine for airway rescue without dantrolene. The authors investigated (1) succinylcholine use rates, including for airway rescue, in anesthetizing/sedating locations; (2) whether succinylcholine without volatile anesthetics triggers MH warranting dantrolene; and (3) the relationship between dantrolene administration and MH morbidity/mortality.

Measurement and correction of the bulk magnetic susceptibility effects of fat: application in venous oxygen saturation imaging.

Magn Reson Med 2018 Dec 13. Epub 2018 Dec 13.

Department of Biomedical Engineering, University of Alberta, Edmonton, Canada.

Purpose: To develop a correction method for the effects of the magnetic susceptibility of fat (χ ) on the calculation of venous oxygen saturation (SvO ).

Theory: The magnetic field shifts associated with the magnetic susceptibility of deoxyhemoglobin can be used to estimate SvO , a measure of oxygen extraction and metabolism. However, the distinct magnetic susceptibility of fat surrounding targeted veins will give rise to magnetic field perturbations that will extend into the vein and surrounding tissues, potentially confounding the calculation of SvO .

Revisiting the Optimal Nano-Morphology: Towards Amorphous Organic Photovoltaics.

Chem Rec 2018 Dec 13. Epub 2018 Dec 13.

Department of Chemistry and Chemical Engineering, Royal Military College of Canada, Kingston, ON, Canada, K7K 7B4.

Organic photovoltaic cells commonly use an active layer with a polycrystalline bulk heterojunction. However, for simplifying the fabrication process, it may be worthwhile to use an amorphous active layer to lessen the burden on processing to achieve optimal performance. While polymers can adopt amorphous phases, molecular glasses, small molecules that can readily form glassy phases and do not crystallize over time, offer an appealing alternative, being monodisperse species.

Gender differences in symptoms and functional status in patients with atrial fibrillation undergoing catheter ablation.

Pacing Clin Electrophysiol 2018 Dec 13. Epub 2018 Dec 13.

Chapel Hill: Department of Medicine, Division of Cardiology, University of North Carolina, 160 Dental Circle CB#7075, Chapel Hill, NC 27599, USA.

Background: Catheter ablation improves symptoms and quality of life in patients with atrial fibrillation (AF); however, despite its benefit, women are less likely than men to undergo catheter ablation. Women with AF have been described to have more frequent and severe symptoms with a lower quality of life than men, and it is therefore unclear why women are less likely to undergo catheter ablation. We prospectively characterized gender differences in AF symptoms among men and women undergoing ablation at UNC using questionnaire data. Read More

Structure and function of Rnt1p: An alternative to RNAi for targeted RNA degradation.

Wiley Interdiscip Rev RNA 2018 Dec 11:e1521. Epub 2018 Dec 11.

Macromolecular Crystallography Laboratory, National Cancer Institute, Frederick, Maryland.

The double-stranded RNA-binding protein (dsRBP) family controls RNA editing, stability, and function in all eukaryotes. The central feature of this family is the recognition of a generic RNA duplex using highly conserved double-stranded RNA-binding domain (dsRBD) that recognizes the characteristic distance between the minor grooves created by the RNA helix. Variations on this theme that confer species and functional specificities have been reported but most dsRBPs retain their capacity to bind generic dsRNA. Read More

School of Science and the Environment, Grenfell Campus, Memorial University of Newfoundland, Corner Brook, A2H 5G4, Canada.

The literature is replete with information describing the composition of the root lipidome in several plant species grown under various environmental conditions. However, it is unknown to what extent the root membrane lipidome vary between silage-corn genotypes, and how such variation could influence agronomic performances during field cultivation in cool climate. To address this issue, the root membrane lipidome and agronomic performance were assessed for five silage-corn genotypes (Fusion-RR, Yukon-R, A4177G3-RIB, DKC23-17RIB, DKC26-28RIB) cultivated under cool climatic conditions.

Community Violence and Associated Psychological Problems Among Adolescents in the General Population.

J Child Adolesc Trauma 2018 2;11(4):411-420. Epub 2018 Jun 2.

4School of Social Work, Université de Montréal, Montréal, Canada.

Based on a populational survey conducted among 1400 adolescents aged between 12 and 17 years old, the aim of this study is to assess the relationships between their community violence experiences and their psychological health (anger, depressive symptoms, and post-traumatic stress disorder symptoms). One MANOVA confirms that both boys and girls who report at least one incident of physical community violence present more psychological difficulties, especially anger. Subsequent MANOVAs show that anger intensity varies depending on whether the youth was a direct victim or a witness only, as well as on the diversity of the types of violent manifestations and on acquaintance with the perpetrator, whereas the presence of injuries has no significant effect.

An automated bacterial concentration and recovery system for pre-enrichment required in rapid Escherichia coli detection.

Sci Rep 2018 Dec 13;8(1):17808. Epub 2018 Dec 13.

Jiangsu Delin Environmental Protection Technology Co., Ltd., Jiangsu, China.

One of the biggest challenges in rapid low concentration bacterial detection is the pre-concentration or pre-enrichment, which aims to increase bacteria concentration and reduce sample volume for easy bacterial detection. In practical bacterial detection, large-volume water samples with a pathogenic bacterial concentration of less than 1 CFU/mL have to be tested rapidly. The reported biosensors either have insufficient detection limit or have limited capability of handling a sufficiently large water sample. Read More

New Cancer Drug Approvals From the Perspective of a Universal Healthcare System: Analyses of the Pan-Canadian Oncology Drug Review Recommendations.

J Natl Compr Canc Netw 2018 Dec;16(12):1460-1466

CancerCare Manitoba, and University of Manitoba, Winnipeg, Manitoba, Canada.

FDA approvals do not consider cost, but they set the tone for regulatory approvals worldwide, including in countries with universal healthcare where cost-effectiveness, utility, and adoption feasibility are considered rigorously. Data from the pan-Canadian Oncology Drug Review (pCODR), a national drug review system that makes evidence-based funding recommendations to Canada's provinces and territories, were collected. Our objectives were to assess (1) temporal trends in cost and efficacy of drugs reviewed, (2) correlations among magnitude of benefits, cost, and pCODR decisions, and (3) predictors of approvals.

Pulmonary hypertension in chronic lung disease and hypoxia.

Eur Respir J 2018 Dec 13. Epub 2018 Dec 13.

University of Giessen and Marburg Lung Center (UGMLC), Justus-Liebig University Giessen and Member of the German Center for Lung Research (DZL), Giessen, Germany.

Pulmonary hypertension (PH) frequently complicates the course of patients with various forms of chronic lung disease (CLD). CLD-associated PH (CLD-PH) is invariably associated with reduced functional ability, impaired quality of life, greater oxygen requirements and an increased risk of mortality. The aetiology of CLD-PH is complex and multifactorial, with differences in the pathogenic sequelae between the diverse forms of CLD. Read More

More than just sleeping in: a late timing of sleep is associated with health problems and unhealthy behaviours in adolescents.

Sleep Med 2018 Nov 20. Epub 2018 Nov 20.

Department of Psychiatry, McGill University, Montreal, QC, Canada; Institute for Health and Social Policy, McGill University, Montreal, QC, Canada.

Objective: New research suggests that the timing of sleep, or chronotype, affects the mental well-being of adolescents, however evidence of its links to physical health is limited. We investigated the associations between chronotype and various health outcomes and behaviours in a national sample of Canadian adolescents.

Methods: Data were from the 2014 Canadian Health Behaviour in School-Aged Children survey (29,470 students; ages 10-18). Read More

Insulin-like growth factor-1 activates AMPK to augment mitochondrial function and correct neuronal metabolism in sensory neurons in type 1 diabetes.

Mol Metab 2018 Nov 28. Epub 2018 Nov 28.

Division of Neurodegenerative Disorders, St Boniface Hospital Albrechtsen Research Centre, Winnipeg, MB, Canada; Department of Pharmacology and Therapeutics, University of Manitoba, Winnipeg, MB, Canada. Electronic address:

Objective: Diabetic sensorimotor polyneuropathy (DSPN) affects approximately half of diabetic patients leading to significant morbidity. There is impaired neurotrophic growth factor signaling, AMP-activated protein kinase (AMPK) activity and mitochondrial function in dorsal root ganglia (DRG) of animal models of type 1 and type 2 diabetes. We hypothesized that sub-optimal insulin-like growth factor 1 (IGF-1) signaling in diabetes drives loss of AMPK activity and mitochondrial function, both contributing to development of DSPN.
