Estuarine crocodiles in a tropical coastal floodplain obtain nutrition from terrestrial prey

The estuarine crocodile (Crocodylus porosus) is one of the largest and most widespread crocodilians in the world. Although considered an apex species, the role of the estuarine crocodile in aquatic foodwebs is poorly understood; we know what crocodiles ingest, but not what nourishes them. In this study, we used a combination of stable isotope measurements (δ13C, δ15N, and δ34S...

Modeling the effect of surgical sterilization on owned dog population size in Villa de Tezontepec, Hidalgo, Mexico, using an individual-based computer simulation model

Surgical sterilization programs for dogs have been proposed as interventions to control dog population size. Models can be used to help identify the long-term impact of reproduction control interventions for dogs. The objective of this study was to determine the projected impact of surgical sterilization interventions on the owned dog population size in Villa de Tezontepec...

Congress of Neurological Surgeons Systematic Review and Evidence-Based Guideline on Subthalamic Nucleus and Globus Pallidus Internus Deep Brain Stimulation for the Treatment of Patients With Parkinson's Disease: Executive Summary

Is bilateral subthalamic nucleus deep brain stimulation (STN DBS) more, less, or as effective as bilateral globus pallidus internus deep brain stimulation (GPi DBS) in treating motor symptoms of Parkinson's disease, as measured by improvements in Unified Parkinson's Disease Rating Scale, part III (UPDRS-III) scores?

Xenin is a novel anorexigen in goldfish (Carassius auratus)

Xenin, a highly conserved 25 amino acid peptide cleaved from the N-terminus of the coatomer protein alpha (COPA), is emerging as a food intake regulator in mammals and birds. To date, no research has been conducted on xenin biology in fish. This study aims to identify the copa mRNA encoding xenin in goldfish (Carassius auratus) as a model, to elucidate its regulation by feeding...

Simulated N and S deposition affected soil chemistry and understory plant communities in a boreal forest in western Canada

We conducted a simulated nitrogen (N) and sulfur (S) deposition experiment from 2006 to 2012 to answer the following questions: (i) does chronic N and S deposition decrease cation concentrations in the soil and foliage of understory plant species, and (ii) does chronic N and S deposition decrease plant diversity and alter species composition of the understory plant community in a...

A thirty year, fine-scale, characterization of area burned in Canadian forests shows evidence of regionally increasing trends in the last decade

Fire as a dominant disturbance has profound implications on the terrestrial carbon cycle. We present the first ever multi-decadal, spatially-explicit, 30 meter assessment of fire regimes across the forested ecoregions of Canada at an annual time-step. From 1985 to 2015, 51 Mha burned, impacting over 6.5% of forested ecosystems. Mean annual area burned was 1,651,818 ha and varied...

A Culture of Rights: Law, Literature, and Canada, by Benjamin Authers

The need for a law and literature canon has long been contested. Even the classic book by Richard Posner, Law and Literature, engages the question: Although Posner ultimately believes in a canon (having “come to praise Caesar, not to bury him”), he finds any semblance of one currently wanting. Scholars continue to challenge the relevance of literature and literary criticism to a...

Judicial Jurisdiction in Canada: The CJPTA—A Decade of Progress

In 2016, the Court Jurisdiction and Proceedings Transfer Act (“CJPTA”) marked its tenth year in force. Promulgated by the Uniform Law Conference of Canada, and adopted in British Columbia, Saskatchewan and Nova Scotia, the CJPTA was developed to clarify and advance the law of judicial jurisdiction. In a symposium hosted by Osgoode Hall Law School, ten leading scholars were...

General Jurisdiction over Corporate Defendants under the CJPTA: Consistent with International Standards?

“General jurisdiction” refers to a court’s competence to adjudicate disputes arising out of a defendant’s activities anywhere in the world. Absent consent or submission, international instruments reserve general jurisdiction over corporations to the states in which the corporation has its registered office, centre of administration, or principal place of business. The bases of...

The colours and contours of compassion: A systematic review of the perspectives of compassion among ethnically diverse patients and healthcare providers

Objective To identify and describe the perspectives, experiences, importance, and impact of compassionate care among ethnically diverse population groups. Methods A systematic search of peer-reviewed research focused on compassionate care in ethnically diverse populations published between 1946 and 2017 was conducted. Results A total of 2296 abstracts were retrieved, out of which...

Is Latin America Ready to Identify Anaplastic Large Cell Lymphoma in Breast Implants Patients? Regional Encounter During the National Plastic Surgery Meeting in Cancun, Mexico

Introduction Anaplastic large cell lymphoma associated with breast implants is receiving increased attention. Most cases have been reported in Europe, North America (USA and Canada), Australia and New Zealand. Fewer cases have been reported in Latin America (including Mexico), Africa and Asia.MethodsThis report was delivered during our national plastic surgery meeting in Cancun...

Spatial spectral and energy efficiencies of cellular networks limited by co-channel interference and path loss in Nakagami-m fading environment

A comprehensive framework for design of hexagonal cellular network system in terms of spatial spectral and energy efficiencies is presented. The communication environment in the system is assumed to be Nakagami-m fading coupled with simplified path loss model and co-channel interference. Three base station antenna configurations namely, omni, 120° and 60° are considered. Closed...

Identification of polymorphisms in the bovine collagenous lectins and their association with infectious diseases in cattle

Infectious diseases are a significant issue in animal production systems, including both the dairy and beef cattle industries. Understanding and defining the genetics of infectious disease susceptibility in cattle is an important step in the mitigation of their impact. Collagenous lectins are soluble pattern recognition receptors that form an important part of the innate immune...

Sleep habits and strategies of ultramarathon runners

Among factors impacting performance during an ultramarathon, sleep is an underappreciated factor that has received little attention. The aims of this study were to characterize habitual sleep behaviors in ultramarathon runners and to examine strategies they use to manage sleep before and during ultramarathons. Responses from 636 participants to a questionnaire were considered...

New Avenues for Nanoparticle-Related Therapies

Development of nanoparticle-based drug delivery systems has been attempted for the treatment of cancer over the past decade. The enhanced permeability and retention (EPR) effect is the major mechanism to passively deliver nanodrugs to tumor tissue. However, a recent systematic review demonstrated limited success of these studies, with the clearance of nanoparticles by the...

Losses Disguised as Wins Affect Game Selection on Multiline Slots

Multiline slots are exciting games that contain features which make them alluring. One such feature is a loss disguised as a win (LDW); wherein, players win less than they wager (e.g., bet 2 dollars, win back 50 cents), but this net loss is disguised by flashing graphics and winning sounds. Research to date concludes that LDWs are both rewarding and reinforcing. Here, we...

Levels of selected analytes in the emissions of “heat not burn” tobacco products that are relevant to assess human health risks

Consumers of combustible cigarettes are exposed to many different toxicologically relevant substances associated with negative health effects. Newly developed “heat not burn” (HNB) devices are able to contain lower levels of Harmful and Potentially Harmful Constituents (HPHCs) in their emissions compared to tobacco cigarettes. However, to develop toxicological risk assessment...

Diversification and intensification of agricultural adaptation from global to local scales

Smallholder farming systems are vulnerable to a number of challenges, including continued population growth, urbanization, income disparities, land degradation, decreasing farm size and productivity, all of which are compounded by uncertainty of climatic patterns. Understanding determinants of smallholder farming practices is critical for designing and implementing successful...
