Ethnic belonging and chronic disease in Indigenous populations in Canada.

Objectives: Indigenous peoples in Canada endure health inequalities and cultural erosion due to colonial legacies. This study examines the relationship between ethnic belonging and chronic disease patterns among three Indigenous groups: First Nations, Inuit, and Métis.

Methods: We analyzed data from the 2017 Indigenous Peoples Survey of Canada, performing latent class analysis to identify distinct classes among 12 chronic disease indicators.

Local Myoelectric Sensing During Human Colonic Tissue Perfusion.

Anastomotic leakage (AL) is one of the most devastating complications after colorectal surgery. The verification of the adequate perfusion of the anastomosis is essential to ensuring anastomosis integrity following colonic resections. This study aimed to evaluate the efficacy of measuring the electrical activity of the colonic muscularis externa at an anastomosis site for perfusion analysis following colorectal surgery.

A multidimensional assessment of in-host fitness costs of drug resistance in the opportunistic fungal pathogen Candida glabrata.

Drug-resistant microbes typically carry mutations in genes involved in critical cellular functions and may therefore be less fit under drug-free conditions than susceptible strains. Candida glabrata is a prevalent opportunistic yeast pathogen with a high rate of fluconazole resistance (FLZR), echinocandin resistance (ECR), and multidrug resistance (MDR) relative to other Candida. However, the fitness of C.

Petunia PHYTOCHROME INTERACTING FACTOR 4/5 transcriptionally activates key regulators of floral scent.

Floral scent emission of petunia flowers is regulated by light conditions, circadian rhythms, ambient temperature and the phytohormones GA and ethylene, but the mechanisms underlying sensitivity to these factors remain obscure. PHYTOCHROME INTERACTING FACTORs (PIFs) have been well studied as components of the regulatory machinery for numerous physiological processes. Acting redundantly, they serve as transmitters of light, circadian, metabolic, thermal and hormonal signals.

The problematic nature of existing explanations for differential immigrant mortality: Insights from a comparative cross-national systematic review and meta-analysis.

Empirical studies in multiple disciplines have frequently observed an immigrant mortality advantage. Yet, questions remain regarding the possible mechanisms underlying this phenomenon. We obtained data from 61 studies of relative immigrant mortality from single origin-destination country pairings, providing information on immigrants from 77 origin countries.

Symbolic boundary work: Jewish and Arab femicide in Israeli Hebrew newspapers.

We analyze 391 news reports in Israeli newspapers between 2013 and 2015, covering murders of women and their family members by other family members and intimate partners. We compare articles where the perpetrators and victims are Jewish to those where the perpetrators and victims are Palestinian citizens of Israel (henceforth PCI). We found that articles tend to provide much more details about Jewish culprits than about PCI ones.

Reactive oxidant species induced by antifungal drugs: identity, origins, functions, and connection to stress-induced cell death.

Reactive oxidant species (ROS) are unstable, highly reactive molecules that are produced by cells either as byproducts of metabolism or synthesized by specialized enzymes. ROS can be detrimental, e.g.

The R2R3-MYB transcription factor EVER controls the emission of petunia floral volatiles by regulating epicuticular wax biosynthesis in the petal epidermis.

The epidermal cells of petunia (Petunia × hybrida) flowers are the main site of volatile emission. However, the mechanisms underlying the release of volatiles into the environment are still being explored. Here, using cell-layer-specific transcriptomic analysis, reverse genetics by virus-induced gene silencing and clustered regularly interspaced short palindromic repeat (CRISPR), and metabolomics, we identified EPIDERMIS VOLATILE EMISSION REGULATOR (EVER)-a petal adaxial epidermis-specific MYB activator that affects the emission of volatiles.

Overlooked petites are echinocandin tolerant, induce host inflammatory responses, and display poor fitness.

is a major fungal pathogen, which is able to lose mitochondria and form small and slow-growing colonies, called "petite." This attenuated growth rate has created controversies and questioned the clinical importance of petiteness. Herein, we have employed multiple omics technologies and mouse models to critically assess the clinical importance of petite phenotype.

Overlooked petites are echinocandin tolerant, induce host inflammatory responses, and display poor fitness.

Unlabelled: Small colony variants (SCVs) are relatively common among some bacterial species and are associated with poor prognosis and recalcitrant infections. Similarly, - a major intracellular fungal pathogen - produces small and slow-growing respiratory-deficient colonies, termed "petite." Despite reports of clinical petite .

Developmental and temporal changes in petunia petal transcriptome reveal scent-repressing plant-specific RING-kinase-WD40 protein.

In moth-pollinated petunias, production of floral volatiles initiates when the flower opens and occurs rhythmically during the day, for optimal flower-pollinator interaction. To characterize the developmental transcriptomic response to time of day, we generated RNA-Seq databases for corollas of floral buds and mature flowers in the morning and in the evening. Around 70% of transcripts accumulating in petals demonstrated significant changes in expression levels in response to the flowers' transition from a 4.

Macrophage internalization creates a multidrug-tolerant fungal persister reservoir and facilitates the emergence of drug resistance.

Candida glabrata is a major fungal pathogen notable for causing recalcitrant infections, rapid emergence of drug-resistant strains, and its ability to survive and proliferate within macrophages. Resembling bacterial persisters, a subset of genetically drug-susceptible C. glabrata cells can survive lethal exposure to the fungicidal echinocandin drugs.

SCARECROW-like GRAS protein PES positively regulates petunia floral scent production.

Emission of scent volatiles by flowers is important for successful pollination and consequently, reproduction. Petunia (Petunia hybrida) floral scent is formed mainly by volatile products of the phenylpropanoid pathway. We identified and characterized a regulator of petunia scent production: the GRAS protein PHENYLPROPANOID EMISSION-REGULATING SCARECROW-LIKE (PES).

Determinants of fluconazole resistance and echinocandin tolerance in isolates causing a large clonal candidemia outbreak among COVID-19 patients in a Brazilian ICU.

Patients presenting with severe COVID-19 are predisposed to acquire secondary fungal infections such as COVID-19-associated candidemia (CAC), which are associated with poor clinical outcomes despite antifungal treatment. The extreme burden imposed on clinical facilities during the COVID-19 pandemic has provided a permissive environment for the emergence of clonal outbreaks of multiple species, including and . Here we report the largest clonal CAC outbreak to date caused by fluconazole resistant (FLZR) and echinocandin tolerant (ECT) .

Determinants of fluconazole resistance and the efficacy of fluconazole and milbemycin oxim combination against clinical isolates from Brazil and Turkey.

Fluconazole-resistant (FLZR-CP) outbreaks are a growing public health concern and have been reported in numerous countries. Patients infected with FLZR-CP isolates show fluconazole therapeutic failure and have a significantly increased mortality rate. Because fluconazole is the most widely used antifungal agent in most regions with outbreaks, it is paramount to restore its antifungal activity.

Implantation of an Impedance Sensor for Early Detection of Gastrointestinal Anastomotic Leaks.

Introduction: Accurate early diagnosis of a gastrointestinal anastomotic leak remains a challenge. When an anastomotic leak develops, the electrical properties of the tissue undergoing inflammatory processes change, resulting from the extravasation of inflammatory fluid and cellular infiltration. The method described here intends to provide a novel early anastomotic leak warning system based upon measurable changes in tissue impedance nearby an acute inflammatory process.

Bacteria and Bellicosity: Photoperiodic Shifts in Gut Microbiota Drive Seasonal Aggressive Behavior in Male Siberian Hamsters.

The existence of a microbiome-gut-brain axis has been established wherein gut microbiota significantly impacts host behavior and physiology, with increasing evidence suggesting a role for the gut microbiota in maintaining host homeostasis. Communication between the gut microbiota and the host is bidirectional, and shifts in the composition of the gut microbiota are dependent on both internal and external cues (host-derived signals, such as stress and immunity, and endocrine and environmental signals, such as photoperiod). Although there is host-driven seasonal variation in the composition of the microbiota, the mechanisms linking photoperiod, gut microbiota, and host behavior have not been characterized.

Size and structure effects on platinum nanocatalysts: theoretical insights from methanol dehydrogenation.

Methanol dehydrogenation on Pt nanoparticles was studied as a model reaction with the focus on size and structure effects employing the density functional theory approach. The effect of cluster morphology is manifested by the higher adsorption energy of COH intermediates on vertexes and edges of model nanoparticles compared to closely packed terraces. Moreover, due to the size effect, the adsorption sites of Pt nanoparticles (1.

"This is a political movement, friend": Why "incels" support violence.

How do members of extremist groups think about violence conducted by individual members on the group's behalf? We examine the link between extremism-motivated violence and extremist groups through a case study of misogynist incels, a primarily online community of men who lament their lack of sexual success with women. To learn how misogynist incels talk about mass violence committed by members of their group, we conduct a qualitative content analysis of 3,658 comments relating to the 2018 Toronto van attack, in which self-declared incel Alek Minassian drove a van into pedestrians, killing 10 and injuring 16. We find overwhelming support among self-proclaimed incels for the attack and violence more generally.

Comparative genomic analysis of clinical isolates identifies multiple polymorphic loci that can improve existing multilocus sequence typing strategy.

is the second leading cause of candidemia in many countries and is one of the most concerning yeast species of nosocomial importance due to its increasing rate of antifungal drug resistance and emerging multidrug-resistant isolates. Application of multilocus sequence typing (MLST) to clinical isolates revealed an association of certain sequence types (STs) with drug resistance and mortality. The current MLST scheme is based on single nucleotide polymorphisms (SNPs) at six loci and is therefore relatively laborious and costly.

Sensitive and robust chemical detection using an olfactory brain-computer interface.

When it comes to detecting volatile chemicals, biological olfactory systems far outperform all artificial chemical detection devices in their versatility, speed, and specificity. Consequently, the use of trained animals for chemical detection in security, defense, healthcare, agriculture, and other applications has grown astronomically. However, the use of animals in this capacity requires extensive training and behavior-based communication.
