BACKGROUND: Major depression (MD) is caused by a combination of genetic and environmental factors. In this study we investigated the interaction of variations in the G-protein beta 3 subunit (GNB3) and cAMP response element binding protein 1 (CREB1) genes with negative life events in the pathogenesis of MD. One GNB3 polymorphism (rs5443) and four CREB1 polymorphisms (rs2253206, rs2551941, rs6740584, rs11904814) were investigated based on known associations with MD. METHODS: 512 patients with MD and 513 control subjects were genotyped...

Polymeric nanoparticles such as PLGA-based nanoparticles are emerging as promising carriers for controlled drug delivery. However, little is known about the intracellular trafficking network of polymeric nanoparticles. Here, more than 30 Rab proteins were used as markers of multiple trafficking vesicles in endocytosis, exocytosis and autophagy to investigate in detail the intracellular trafficking pathways of PLGA nanoparticles. We observed that coumarin-6-loaded PLGA nanoparticles were internalized by the cells mainly through caveolin and clathrin-dependent endocytosis and Rab34-mediated macropinocytosis...

Objective To investigate the clinical feasibility of the injection test for balloon placement during oesophageal pressure measurement in patients without spontaneous breathing. Methods The injection test was performed in 12 mechanically ventilated patients under deep sedation and paralysis. During withdrawal of the balloon from the stomach and air injection into the gastric lumen of the catheter, the presence of the injection test wave in the balloon pressure tracing indicated that the whole balloon was positioned above the lower oesophageal sphincter (LES)...

The theory of the treadmill of production highlights how the constant search for economic growth leads to advanced economies being stuck on a "treadmill," where their well-being is not improved by economic growth, yet the impacts of this pursuit of growth causes massive, unsustainable environmental damages. In interrogating the specific driving force that keeps the irrational system of the treadmill so powerfully in place, the theory of the treadmill of production focuses on how those who control the production process, corporations, are the primary agents driving the treadmill, while also highlighting how the state and workers generally continue to provide support for the treadmill's continued reproduction...

At many Canadian universities it is now common to publicly acknowledge Indigenous lands, treaties, and peoples. Yet, this practice has yet to be considered as a subject of scholarly inquiry. How does this practice vary and why? In this paper we describe the content and practice of acknowledgment, linking this content to treaty relationships (or lack thereof). We show that acknowledgment tends to be one of five general types: of land and title (British Columbia), of specific treaties and political relationships (Prairies), of multiculturalism and heterogeneity (Ontario), of no practice (most of Quebec), and of people, territory, and openness to doing more (Atlantic)...

Attention to the relationship between nature and society has been a defining feature of environmental sociology since its inception. Early research, incorporating insights from ecology, argued for the need to (1) theorize the causal connections between nature and society and (2) contextualize those connections in terms of biophysical limits resulting from resource scarcity. Over the past two decades, partly in response to new forms of existential threat such as climate change, the treatment of nature and society as distinct entities has given way to a focus on socio-natural assemblages...

On July 6, 2013, Montreal, Maine, and Atlantic railcar 5017 hauling 72 tanker cars of Bakken crude oil derailed over the town of Lac-Mégantic, Quebec. The town erupted in a fiery inferno as 5,560,000 liters of highly flammable Bakken crude oil exploded over the town, killing 47 people and contaminating 558,000 tons of soil and local waterways. While Montreal, Maine, and Atlantic Rail Chairman Edward Burkhardt initially blamed the derailment on the lone engineer and local firefighters, this study shows how Transport Canada and the rail industry undermined regulatory and safety measures for several years before the derailment...

Despite covering around 70 percent of the earth's surface, the ocean has long been ignored by sociology or treated as merely an extension of land-based systems. Increasingly, however, oceans are assuming a higher profile, emerging both as a new resource frontier, a medium for geopolitical rivalry and conflict, and a unique and threatened ecological hot spot. In this article, I propose a new sociological specialty area, the "sociology of oceans" to be situated at the interface between environmental sociology and traditional maritime studies...

BACKGROUND: In the two-stage randomised trial design, a randomly sampled subset of study participants are permitted to choose their own treatment, while the remaining participants are randomised to treatment in the usual way. Appropriate analysis of the data from both arms of the study allows investigators to estimate the impact on study outcomes of treatment preferences that patients may have, in addition to evaluating the usual direct effect of treatment. In earlier work, we showed how to optimise this design by making a suitable choice of the proportion of participants who should be assigned to the choice arm of the trial...

OBJECTIVE: Type 1 diabetes mellitus (T1DM) is a chronic disease, which ranks third in the children under 16 years old. Expressed emotion (EE) is a term that indicates a specific family climate including lack of emotional support (LES), irritability and emotional over-involvement. It is known that the family environment is highly important on glycemic control in diabetic adolescents. In this study the relationship between perceived EE and glycemic control in adolescents diagnosed with T1DM not accompanied by psychopathology will be investigated...

BACKGROUND AND AIMS: Parenterally-administered lipid emulsion (LE) is a key cause of enterocyte apoptosis under total parenteral nutrition, yet the pathogenesis has not been fully understood. CUGBP, Elav-like family member 1 (CELF1) has been recently identified as a crucial modulator of apoptosis, and thus this study sought to investigate its role in the LE-induced apoptosis in vitro. METHODS: Caco-2 cells were used as an in vitro model. The cells were treated with varying LEs derived from soybean oil, olive oil or fish oil, and changes in the apoptosis and CELF1 expression were assessed...

We present a new multi-analytical approach to the characterization of black pigments in Spanish Levantine rock art. This new protocol seeks to identify the raw materials that were used, as well as reconstruct the different technical gestures and decision-making processes involved in the obtaining of these black pigments. For the first of these goals, the pictorial matter of the black figurative motifs documented at the Les Dogues rock art shelter (Ares del Maestre, Castellón, Spain) was characterized through the combination of physicochemical and archeobotanical analyses...

Reducing the exposure of children and young people to the marketing of unhealthy foods is a core strategy for reducing the high overweight and obesity prevalence in this population. The Advertising Standards Authority (ASA) has recently reviewed its self-regulatory codes and proposed a revised single code on advertising to children. This article evaluates the proposed code against eight criteria for an effective code, which were included in a submission to the ASA review process from over 70 New Zealand health professors...

This article considers the extent to which a quarrel might be a strategic activity for a writer or philosopher making a bid for posterity. Inveterate quarrellers like Voltaire or Rousseau come to mind, but the case to be examined here is the far less straightforward case of Diderot and in particular the stance of 'accidental quarreller' that he fabricates in his Essai sur les règnes de Claude et de Néron et sur les moeurs et les écrits de Sénèque pour servir à l'introduction de la lecture de ce philosophe (1782), the last work he published in his lifetime...

Vestibular bouton afferent terminals in turtle utricle can be categorized into four types depending on their location and terminal arbor structure: lateral extrastriolar (LES), striolar, juxtastriolar, and medial extrastriolar (MES). The terminal arbors of these afferents differ in surface area, total length, collecting area, number of boutons, number of bouton contacts per hair cell and axon diameter (Huwe et al. 2015). To understand how differences in terminal morphology and the resulting hair cell inputs might affect afferent response properties, we modeled representative afferents from each region, using reconstructed bouton afferents (Huwe et al...

A large eddy simulation (LES) model coupled with O3-NOx-VOC chemistry is implemented to simulate the coupled effects of emissions, mixing and chemical pre-processing within an idealised deep (aspect ratio = 2) urban street canyon under a weak wind condition. Reactive pollutants exhibit significant spatial variations in the presence of two vertically aligned unsteady vortices formed in the canyon. Comparison of the LES results from two chemical schemes (simple NOx-O3 chemistry and a more comprehensive Reduced Chemical Scheme (RCS) chemical mechanism) shows that the concentrations of NO2 and Ox inside the street canyon are enhanced by approximately 30-40% via OH/HO2 chemistry...

The aim of the present study was to characterize the multi-scale structures of ternary complexes of a model system of starch, fatty acid (FA) and β-lactoglobulin (βLG) prepared using a Rapid Visco Analyser (RVA). The addition of βLG to starch-lauric acid or starch-oleic acid RVA pastes resulted in the increased intensity or occurrence of a new viscosity peak during cooling when the RVA protocol was repeated. The viscosity peak was attributed to the formation of starch-βLG-FA complexes. Differential scanning calorimetry (DSC) results showed clearly that starch-βLG-FAs complex was formed as gelatinized starch was cooled in the presence of βLG and FAs...

Recently, it has been suggested that internal transcribed spacer (ITS) sequences are under selective constraints to preserve their secondary structure. Here, we investigate the patterns of the ITS nucleotide and secondary structure conservation across the Passiflora L. genus to evaluate the potential use of secondary structure data as a helpful tool for the alignment in taxonomically complex genera. Considering the frequent use of ITS, this study also presents a perspective on future analyses in other plant groups...
