Body Temperature Regulation in Domestic Dogs After Agility Trials: The Effects of Season, Training, Body Characteristics, Age, and Genetics.

An animal's body mass is said to be indirectly related to its rate of heat loss; that is, smaller animals with higher surface area to volume tend to lose heat faster than larger animals. Thus, thermoregulation should be related to body size, however, generalizable patterns are still unclear. Domestic dogs are a diverse species of endothermic mammals, including a 44-fold difference in body size.

Sex- and Substance-Specific Associations of Circadian-Related Genes with Addiction in the UK Biobank Cohort Implicate Neuroplasticity Pathways.

Background/objectives: The circadian clockwork is implicated in the etiology of addiction, with circadian rhythm disruptions bidirectionally linked to substance abuse, but the molecular mechanisms that underlie this connection are not well known.

Methods: Here, we use machine learning to reveal sex- and substance-specific associations with addiction in variants from 51 circadian-related genes (156,702 SNPs) in 98,800 participants from a UK Biobank cohort. We further analyze SNP associations in a subset of the cohort for substance-specific addictions (alcohol, illicit drugs (narcotics), and prescription drugs (opioids)).

Associating Race, Income, and Discrimination with COVID-19 Vaccine Status, Hesitancy, and Access in the United States: A Cross-sectional Study.

There is an emerging literature exploring the role of discrimination in vaccine hesitancy, particularly among Black individuals. The goal of the present research is to explore how COVID-19 vaccine hesitancy, vaccine status, and vaccine access are associated with race, income, and discrimination. A quota sample of 798 Black/White and low/high income participants from the United States completed an online survey between March 8 and April 19, 2023.

Hematological and immunological profiles of podoconiosis patients in West Gojjam Zone, Ethiopia: A comparative cross-sectional study.

Background: Podoconiosis is a geo-chemically induced, non-infectious, familial, chronic lymphedema of the legs that occurs among barefoot people in rural, farming communities with extreme poverty. Despite a growing body of research surrounding the disease, the pathogenesis of the disease is relatively unknown. This study aims to investigate the immunological and hematological profiles of individuals affected by podoconiosis in comparison to healthy controls.

A Forgotten Millstone: Denialism and Child Abuse in the Christian Church.

Christianity was founded on the teachings of Jesus, whose words emphasize protecting and honoring children. Jesus' teachings are historically unique for the period with his emphasis on safeguarding children, but the church moved away from this focus. First century Christianity adopted protections for children and harsh consequences for those who would abuse a child.

Fentanyl exposure alters rat CB1 receptor expression in the insula, nucleus accumbens and substantia nigra.

Prolonged periods of opioid use have been shown to cause neuroadaptations in the brain's reward circuitry, contributing to addictive behaviors and drug dependence. Recently, considerable focus has been placed on the role of the endocannabinoid system (ECS) and its CB receptors in opioid-driven behaviors. However, opioid-induced neuroadaptations to the ECS remain understudied.

Demographic, morphological and coat factors in dogs after exercise at a fast course ability test (FCAT) trial.

Domestic dogs are a widely diverse species of endothermic mammals that show a positive correlation between body mass and whole-animal metabolic rate, but a negative correlation between body mass and lifespan, making them an interesting system for determining thermoregulatory patterns in relation to body mass, body morphology, and age within a single mammalian species. Though previous work has found differences in thermoregulation across seasons and with training in dogs of different sizes, we now seek to determine (1) whether sampling event-related temperature differences remained when dogs exercised intensely and acutely outdoors and (2) whether thermal differences were also expressed in short-term burst exercise in athletic dogs compared to long-term exercise in non-athletic dogs, as previously found. Here, we measured tympanic membrane temperature (T) as a correlate of core or internal body temperature (T).

Patient Panel Handoffs for New Interns in Internal Medicine Residency Continuity Clinics.

Background: Compared to inpatient care transitions, end-of-year resident continuity clinic panel transitions affect a greater number of patients, yet warm handoffs occur less often.

Objective: We developed a program-wide curriculum to implement warm handoffs (defined as in-person or virtual via videoconference) for high-risk continuity clinic patients between graduating and incoming residents.

Methods: The warm handoff intervention was phased in at different clinic sites over the study period and ultimately implemented program-wide across nine affiliated continuity clinics.

Increased Risk of Hypoglycemia Following Roux-en-Y Gastric Bypass Surgery in Patients Without Diabetes: a Propensity Score-Matched Analysis.

Background: Roux-en-Y gastric bypass (RYGB) surgery is an effective treatment for obesity. However, the incidence and long-term risk of hypoglycemia after surgery in patients without diabetes remains unclear. This study aimed to investigate the prevalence of hypoglycemia following RYGB surgery in patients with obesity and without diabetes.

Autocatalytic Activation of a Ruthenium-PNN-Pincer Hydrogenation Catalyst.

In this article, we describe a detailed experimental and computational study of the activation mechanism for a highly active pincer ruthenium(0) precatalyst for the hydrogenation of polar organic compounds. The precatalyst activates by reaction with 2 equiv of hydrogen, resulting in a net oxidative addition to ruthenium and hydrogenation of an imine functional group on the supporting ligand. The kinetics of precatalyst hydrogenation were measured by UV-visible spectroscopy under catalytically relevant conditions (10-39 bar hydrogen, 298 K).

White Americans who perceive themselves to be "last place" in the racial status hierarchy are most drawn to alt-right extremism.

Economic inequality and alt-right extremism have reached historic highs in the U.S. We propose that high economic inequality may uphold stereotypes that white people are wealthy which may lead some white Americans to feel in the precarious position of falling behind their racial group's high status.

Is Discrimination Widespread or Concentrated? Evaluating the Distribution of Anti-Black Discrimination in Judicial, Hiring, and Housing Decisions.

Is anti-Black discrimination concentrated among a discriminatory few, or widespread across many decision-makers? The handful of studies that have addressed this question have reached divergent conclusions, with some suggesting that discrimination follows the 80/20 rule (i.e., a Pareto distribution) and others suggesting that discrimination is normally distributed.

Dendritic Spine Quantification Using an Automatic Three-Dimensional Neuron Reconstruction Software.

Synaptic connections allow for the exchange and processing of information between neurons. The post-synaptic site of excitatory synapses is often formed on dendritic spines. Dendritic spines are structures of great interest in research centered around synaptic plasticity, neurodevelopment, and neurological and psychiatric disorders.

Effects of Adverse Life History on Oxidative Stress and Cytokine Concentration in Domestic Dogs.

Early-life stress has been well studied in humans and laboratory animals; however, the impacts of similar adversity on the welfare of domestic dogs has recently begun to be addressed. For example, associations between processes linked to mitochondrial function, such as oxidative stress (OS) and proinflammatory immune systems, have been under-researched. Yet, mitochondria are targets and mediators of stress pathologies.

The resistance of domestic canine skin-derived fibroblasts to oxidative and non-oxidative chemical injury: implications of breed and body size.

Small-breed dogs live significantly longer lives than large-breed dogs, while having higher mass-specific metabolic rates and faster growth rates. Underlying this observed physiological difference across domestic dogs, there must also be differences at other levels of organization that could lead to elucidating what accounts for the disparity in aging rates and life span within this species. At the cellular level, a clear mechanism underlying whole animal traits has not been fully elucidated.

The impact of real-time feedback on ventilation quality during out-of-hospital cardiac arrest: A before-and-after study.

Introduction: Ventilations are a critical component of cardiopulmonary resuscitation (CPR). There is conflicting evidence, however, on the most appropriate method of ventilation during cardiac arrest management. Recent evidence has suggested that regardless of the optimal ventilation strategy, ventilations are often not delivered compliant with guideline recommendations.

Social and ecological determinants of antimicrobial resistance in Africa: a systematic review of epidemiological evidence.

Background: Antimicrobial resistance (AMR) is one of the greatest global health problems for humans, animals, and the environment. Although the association between various factors and AMR is being increasingly researched, the need to understand the contribution of social and ecological determinants, especially in developing nations, remains. This review fills these knowledge gaps by synthesizing existing evidence on the social and ecological determinants of AMR in Africa.
