Background:Tanacetum vulgare L. (Asteraceae) is a perennial herb that has been used to treat multiple ailments. Regional variability of the chemical composition of T. vulgare essential oils is well-known. Despite these regional chemotypes, most relevant studies did not analyze the complete chemical composition of the T. vulgare essential oil and its constituents in relation to their biological activities. Here, we assess the anti-inflammatory, antioxidant, antibacterial, and cytotoxic activities of T. vulgare collected from northern Quebec (Saguenay-Lac-St-Jean), Canada...

Child maltreatment has been associated with sexual risk behaviors. Previous investigators have typically studied only one form of maltreatment, preventing them from exploring interrelations between forms of maltreatment and their impact on sexual risk behaviors. Thus, this study aims to examine the unique, cumulative, and interactive effects of four maltreatment forms (sexual abuse, physical abuse, neglect, and witnessing interparental violence) on sexual risk behaviors. The sample comprised 1940 sexually active adolescents (Mage=15...

AIMS: We assessed the long-term risk of cataract following a pregnancy complicated by gestational diabetes. METHODS: We carried out a longitudinal cohort study of 1,108,541 women who delivered infants between 1989-2013 in Quebec, Canada, with follow-up extending up to 25years later. The cohort included 71,862 women with gestational diabetes and 5247 with cataracts. We used Cox regression models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of gestational diabetes with subsequent risk of cataract, adjusted for age, parity, socioeconomic status, time period, comorbidity, and type 2 diabetes...

INTRODUCTION: Food marketing impacts children's food knowledge, behaviours and health. Current regulations in Canada focus on restricting promotional aspects of food marketing with little-to-no consideration of the places where children experience food. Understanding food marketing in children's everyday settings is necessary to protect children. This scoping review describes the current literature on food marketing to children in Canada by setting. METHODS: The author searched databases for Canadian research on children's exposure to food marketing, and the power and impact of food marketing to children (2-17 years) across settings, and on how current regulations may mediate the effect of food marketing on children...

A recent scientific discipline, bioinformatics, defined as using informatics for the study of biological problems, is now a requirement for the study of biological sciences. Bioinformatics has become such a powerful and popular discipline that several academic institutions have created programs in this field, allowing students to become specialized. However, biology students who are not involved in a bioinformatics program also need a solid toolbox of bioinformatics software and skills. Therefore, we have developed a completely online bioinformatics course for non-bioinformaticians, entitled "BIF-1901 Introduction à la bio-informatique et à ses outils (Introduction to bioinformatics and bioinformatics tools)," given by the Department of Biochemistry, Microbiology, and Bioinformatics of Université Laval (Quebec City, Canada)...

BACKGROUND: Little is known about the epidemiology of interstitial lung disease (ILD) amongst Canada's Indigenous populations. Clinicians working in Eeyou Istchee (the Cree territory of the James Bay region of Québec, population 17, 956) suspected that ILD was more common in this area. We sought to identify all prevalent and incident cases of ILD in Eeyou Istchee between 2006 and 2013, to describe characteristics of affected patients, distribution of subtypes, and estimate disease incidence...

To quantify CO2 emissions from water surface of a reservoir that was shaped by flooding the boreal landscape, we developed a daily time-step reservoir biogeochemistry model. We calibrated the model using the measured concentrations of dissolved organic and inorganic carbon (C) in a young boreal hydroelectric reservoir, Eastmain-1 (EM-1), in northern Quebec, Canada. We validated the model against observed CO2 fluxes from an eddy covariance tower in the middle of EM-1. The model predicted the variability of CO2 emissions reasonably well compared to the observations (root mean square error: 0...

OBJECTIVES: High-flow nasal cannula is increasingly used in the management of respiratory failure. However, little is known about its impact on respiratory effort, which could explain part of the benefits in terms of comfort and efficiency. This study was designed to assess the effects of high-flow nasal cannula on indexes of respiratory effort (i.e., esophageal pressure variations, esophageal pressure-time product/min, and work of breathing/min) in adults. DESIGN: A randomized controlled crossover study was conducted in 12 patients with moderate respiratory distress (i...

A fast and high-throughput method is proposed for the determination of total microcystins (ΣMC) in environmental surface waters. After a 1-h Lemieux-von Rudloff oxidation step to yield the 2-methyl-3-methoxy-4-phenylbutyric acid (MMPB) moiety, samples were quenched, filtered, and directly analyzed. This was achieved via solid phase extraction (SPE) coupled on-line to ultra-high performance liquid chromatography electrospray ionization triple stage quadrupole mass spectrometry. The choice of on-line SPE settings was conducted using experimental designs...
