INTRODUCTION: Both health equity research and Indigenous health research are driven by the goal of promoting equitable health outcomes among marginalized and underserved populations. However, the two fields often operate independently, without collaboration. As a result, Indigenous populations are underrepresented in health equity research relative to the disproportionate burden of health inequities they experience. In this methodological article, we present Xpey' Relational Environments, an analytic framework that maps some of the barriers and facilitators to health equity for Indigenous peoples...

AIMS: Classical microbiology techniques are the gold standard for probiotic enumeration. However, these techniques are limited by parameters of time, specificity and incapacity to detect viable but non-culturable (VBNC) microorganisms and non-viable cells. The aim of the study was to evaluate flow cytometry as a novel method for the specific quantification of viable and non-viable probiotics in multi-strain products. METHODS AND RESULTS: Custom polyclonal antibodies were produced against five probiotic strains from different species (Bifidobacterium bifidum R0071, Bifidobacterium longum ssp...

The study aims to investigate the analgesic effects of microRNA-129-5p (miR-129-5p) on bone cancer pain (BCP) by targeting Eph receptor B1 (EphB1) through the EphB1/EphrinB2 signaling pathway. BCP mice models were established, and C3H/HeJ female mice were classified into the normal, blank, negative control (NC), miR-129-5p mimics, miR-129-5p inhibitors, EphB1 knockout (KO), and miR-129-5p inhibitors + EphB1 KO groups. RT-qPCR and western blotting were used to evaluate miR-129-5p expression, and mRNA and protein expressions of EphB1, p-EphB1, EphrinB2 and p-EphrinB2...

Transitioning of rhinologic procedures from the operating room to the office setting in selected patients is a rising trend. An effective pain-control, patient-preparation protocol is essential, especially with advanced in-office rhinologic procedures such as hybrid balloon sinus dilation (BSD), in which other procedures such as ethmoidectomy, turbinate reduction, and other procedures are concomitantly performed. A regimen using oral sedation, topical tetracaine gel, topical tetracaine/epinephrine-soaked cottonoid packs, and intranasal local infiltrative anesthesia can vary significantly in effectiveness and be suboptimal at times (as determined by using treated patients as historical controls)...

Historically, head and neck injuries constituted 16 to 20% of all nonfatal combat injuries. However, advances in body and vehicle armor in the context of the use of ambushes and improvised explosive devices by enemy combatants have resulted in fewer fatalities from head and neck wounds, and thus the incidence of nonfatal head and neck injuries has risen to as high as 52%. Despite this increase, data regarding specific injury distributions, surgical cases, and approaches to repair are lacking in the current literature...

Graduate medical education programs typically set up call under the assumption that residents will have similar experiences. The terms black cloud and white cloud have frequently been used to describe residents with more difficult (black) or less difficult (white) call experiences. This study followed residents in the department of head and neck surgery during call to determine whether certain residents have a significantly different call experience than the norm. It is a prospective observational study conducted over 16 months in a tertiary care center with a resident training program in otolaryngology...

In 2016, the Children's Hospital of Eastern Ontario (CHEO) announced the settlement of its patent lawsuit against US-based Transgenomic, Inc. At issue in the case was CHEO's ability to test for gene mutations associated with long QT syndrome (LQTS) that are described in Transgenomic's patents. CHEO challenged the patents as invalid, and Transgenomic ultimately agreed to license them on a royalty-free basis to CHEO and other healthcare institutions for LQTS testing and research. While widely celebrated in the media, the ethical rhetoric surrounding the settlement has at times obscured the practical and legal context in which it was made and will operate...

INTRODUCTION: Many authors have reported on a myopic post-operative refractive prediction error when combining phacoemulsification with pars plana vitrectomy (phacovitrectomy). In this study we evaluate the amount of this error in our facility and try to elucidate the various factors involved. METHODS: This was a retrospective study which included 140 patients who underwent phacovitrectomy (39 with macular holes, 88 with puckers, and 13 with floaters). Post-operative refractive error was defined as the difference between the actual spherical equivalent (SEQ) and expected SEQ based on the SRK/T and Holladay-II formulas...

BACKGROUND: A lack of clarity remains over the optimal strategy for the management of laparoscopic adjustable gastric band (LAGB) slippage, which, although rare (around 3% in our experience), can when acute result in obstruction, gastric erosion or ischaemia. Typically, slipped bands are removed acutely. The aim of this study was to explore outcomes following immediate or delayed resiting of slipped LAGBs in a single centre, comparing simple repositioning with retunnelling and replacement...

We explored the use of pulsed flow modulation (PFM) two-dimensional comprehensive gas chromatography (GCxGC) mass spectrometry with supersonic molecular beams (SMB) (also named Cold electron ionization (EI)) for achieving universal pesticide analysis in agricultural products. The use of GCxGC serves as an alternative to MS-MS in the needed reduction of matrix interference while enabling full-scan MS operation for universal pesticide analysis with reduced number of false negatives. Matrix interference is further reduced with Cold EI in view of the enhancement of the molecular ions...

Microwave-assisted and ultrasound-assisted extraction assays were used to isolate total flavonoids (TF) from Osmanthus fragrans flowers. The effects of the solid-liquid ratio, ethanol concentration, microwave power, microwave extraction time, ultrasonic power and ultrasonic extraction time on the yield of TF were studied. A sequential combination of microwave- and ultrasound-assisted extraction (SC-MUAE) methods was developed, which was subsequently optimized by Box-Behnken design-response surface methodology (BBD-RSM)...

Xuexian Gao, Haidong Zheng
Environmental regulators often use environmental policy to induce green investment by firms. However, if an environmental policy fails to exert a long-run effect on regulating the economic agents' behavior, it may be more reasonable to think of the firm as the leader in the game, since the investment in green technology is usually a strategic decision. In this paper, we consider a three-stage Stackelberg game to address the interaction between a profit-maximizing firm (Stackelberg leader) facing emission-dependent demand, and the environmental regulator (Stackelberg follower)...

With respect to multi-attribute group decision-making (MAGDM) problems, where attribute values take the form of interval grey trapezoid fuzzy linguistic variables (IGTFLVs) and the weights (including expert and attribute weight) are unknown, improved grey relational MAGDM methods are proposed. First, the concept of IGTFLV, the operational rules, the distance between IGTFLVs, and the projection formula between the two IGTFLV vectors are defined. Second, the expert weights are determined by using the maximum proximity method based on the projection values between the IGTFLV vectors...

Smart reconfiguration of a dynamic networking environment is offered by the central control of Software-Defined Networking (SDN). Centralized SDN-based management architectures are capable of retrieving global topology intelligence and decoupling the forwarding plane from the control plane. Routing protocols developed for conventional Wireless Sensor Networks (WSNs) utilize limited iterative reconfiguration methods to optimize environmental reporting. However, the challenging networking scenarios of WSNs involve a performance overhead due to constant periodic iterative reconfigurations...

N2O-production was investigated during nitrogen removal using aerobic granular sludge (AGS) technology. A pilot sequencing batch reactor (SBR) with AGS achieved an effluent in accordance with national discharge limits, although presented a nitrite accumulation rate of 95.79% with no simultaneous nitrification-denitrification. N2O production was 2.06 mg L-1 during the anoxic phase, with N2O emission during air pulses and the aeration phase of 1.6% of the nitrogen loading rate. Batch tests with AGS from the pilot reactor verified that at the greatest COD/N ratio (1...
