Deeply branching species exhibit atypical Gram-negative staining.

Unlabelled: The Gram staining method differentiates bacteria based on their cell envelope structure, with the monoderm and diderm cell envelope types traditionally being synonymous with Gram-positive and Gram-negative stain results, respectively. Monoderms have a single phospholipid membrane surrounded by a thick layer of peptidoglycan, while diderms have a lipopolysaccharide outer membrane exterior to a thin peptidoglycan layer. The (formerly ) phylum has members with both cell wall types, and recent phylogenetic analyses have shown that monoderm evolved from diderm ancestors on multiple occasions.

Scalp surface estimation and head registration using sparse sampling and 3D statistical models.

Registering the head and estimating the scalp surface are important for various biomedical procedures, including those using neuronavigation to localize brain stimulation or recording. However, neuronavigation systems rely on manually-identified fiducial head targets and often require a patient-specific MRI for accurate registration, limiting adoption. We propose a practical technique capable of inferring the scalp shape and use it to accurately register the subject's head.

Objective: The current scoping literature review aimed to explore the factors fostering wellbeing and causing burnout among school teachers.

The Selah Pilot Study of Spiritual, Mindfulness, and Stress Inoculation Practices on Stress-Related Outcomes Among United Methodist Clergy in the United States.

The job-demand-control-support model indicates that clergy are at high risk for chronic stress and adverse health outcomes. A multi-group pre-test-post-test design was used to evaluate the feasibility, acceptability, and range of outcome effect sizes for four potentially stress-reducing interventions: stress inoculation training, mindfulness-based stress reduction (MBSR), the Daily Examen, and Centering Prayer. All United Methodist clergy in North Carolina were eligible and recruited via email to attend their preferred intervention.

Microbe-Mineral Interactions between Asbestos and Thermophilic Chemolithoautotrophic Anaerobes.

The Fe content and the morphometry of asbestos are two major factors linked to its toxicity. This study explored the use of microbe-mineral interactions between asbestos (and asbestos-like) minerals and thermophilic chemolithoautotrophic microorganisms as possible mineral dissolution treatments targeting their toxic properties. The removal of Fe from crocidolite was tested through chemolithoautotrophic Fe(III) reduction activities at 60°C.

Can short-term data accurately model long-term environmental exposures? Investigating the multigenerational adaptation potential of Daphnia magna to environmental concentrations of organic ultraviolet filters.

Organic ultraviolet filters (UVFs) are contaminants of concern, ubiquitously found in many aquatic environments due to their use in personal care products to protect against ultraviolet radiation. Research regarding the toxicity of UVFs such as avobenzone, octocrylene and oxybenzone indicate that these chemicals may pose a threat to invertebrate species; however, minimal long-term studies have been conducted to determine how these UVFs may affect continuously exposed populations. The present study modeled the effects of a 5-generation exposure of Daphnia magna to these UVFs at environmental concentrations.

The Gap in Mental Health Service Utilization Among United Methodist Clergy with Anxiety and Depressive Symptoms.

Clergy are tasked with multiple interpersonal administrative, organizational, and religious responsibilities, such as preaching, teaching, counseling, administering sacraments, developing lay leader skills, and providing leadership and vision for the congregation and community. The high expectations and demands placed on them put them at an increased risk for mental distress such as depression and anxiety. Little is known about whether and how clergy, helpers themselves, receive care when they experience mental distress.

Alteration of yellow traffic paint in simulated environmental and biological fluids.

Pollution from heavy metals in urban environments is a topic of growing concern because many metals, including Pb and Cr, are a human health hazard. Exposure to Pb and Cr has been linked to the inhibition of neurological development as well as toxic effects on many organs. Yellow traffic paint (YTP) is a mixture that contains organic polymers, binders, and pigments, which in some cases consist of crocoite (PbCrO) that may be coated by silica.

Academic-Practice Partnership for Caregiver Training and Support: The Duke Elder Family/Caregiver Training (DEFT) Center.

After a hospital stay, many older adults rely on their caregivers for assistance at home. Empirical evidence demonstrates that caregiver support programs in hospital-to-home transitions are associated with favorable caregiver and patient outcomes. We tested the feasibility of implementing the Duke Elder Family/Caregiver Training (DEFT) program in an academic medical center.

A feasibility study of conducting surveillance for swine pathogens in slurry from North Carolina swine farms.

Despite close contact between humans and animals on large scale farms, little to no infectious disease research is conducted at this interface. Our goal in this preliminary study was to explore if we could detect swine pathogens using a non-invasive, indirect approach through the study of swine slurry. From April to November 2018, 105 swine slurry samples were collected by farm personnel from waste pits at two sites on a swine farm in North Carolina.

Dimensional distribution control of elongate mineral particles for their use in biological assays.

The aim of the present method is to reduce the dimensional variability of asbestos, elongate mineral particles, and other asbestiform minerals for use in biological assays. Here, the pristine mineral sample is filtered through two nylon meshes of different sizes to obtain a narrower dimensional distribution following a power law. Furthermore, we show that anoxic preparation, autoclaving and storage of the mineral prior to addition into biological cultures did not affect the mineral's chemical properties.

Emotional quality-of-life and patient-reported limitation in sports participation in children with uncorrected congenital and acquired heart disease in healthcare-restricted settings in low- and middle-income countries.

Background: Little is known about emotional quality-of-life in paediatric heart disease in low- and middle-income countries where the prevalence of uncorrected lesions is high. Research on emotional quality-of-life and its predictors in these settings is key to planning interventions.

Methods: Ten-year retrospective cross-sectional study of children aged 6-17 years with uncorrected congenital or acquired heart disease in 12 low- and middle-income countries was conducted.

The Magic Touch: A Case Report of How Smartphone Fingerprint Technology Was Utilized to Establish a Last Known Well Time for Recanalization Treatment in a Patient With Acute Ischemic Stroke.

Tissue plasminogen activator (tPA) is currently a standard of care for acute stroke patients. One of the necessary criteria in determining eligibility for tPA is the last known well (LKW) time. The LKW time is unfortunately often difficult to obtain accurately if no witness is available, thus posing as an obstacle for acute recanalization therapy.

A Mini-Review of Adverse Lung Transplant Outcomes Associated With Respiratory Viruses.

Due to their overall immunocompromised state, lung transplant recipients (LTRs) are at increased risk for the development of viral respiratory infections compared to the general population. Such respiratory infections often lead to poor transplant outcomes. We performed a systematic review of the last 30 years of medical literature to summarize the impact of specific respiratory viruses on LTRs.

Mineralogical Characterization and Dissolution Experiments in Gamble's Solution of Tremolitic Amphibole from Passo di Caldenno (Sondrio, Italy).

In nature, asbestos is often associated with minerals and other non-asbestiform morphologies thought to be harmless, but not much is known about the potential toxic effects of these phases. Therefore, the characterization of natural assemblages should not be limited to asbestos fibers only. This paper combines a multi-analytical characterization of asbestos from Valmalenco (Italy) with data from dissolution experiments conducted in a simulated interstitial lung fluid (Gamble's solution), and a detailed dimensional study that compares the particle population before and after this interaction.

KaiHaiDragon belongs to cluster EC, and OneinaGillian is a member of cluster EG.

Molecular surveillance of respiratory viruses with bioaerosol sampling in an airport.

Recognizing that crowded, high-traffic airports and airplanes have been implicated in respiratory disease transmission, we partnered with administrators of Raleigh Durham International Airport (RDU) in conducting a pilot study of aerosol surveillance for respiratory viruses at RDU. From January to March 2018 we used NIOSH 2-stage samplers to collect 150 min aerosol samples in crowded areas at RDU. Four (17%) of the 24 samples were positive for known respiratory pathogens including influenza D virus and adenovirus.

The continual threat of influenza virus infections at the human-animal interface: What is new from a one health perspective?

This year, in 2018, we mark 100 years since the 1918 influenza pandemic. In the last 100 years, we have expanded our knowledge of public health and increased our ability to detect and prevent influenza; however, we still face challenges resulting from these continually evolving viruses. Today, it is clear that influenza viruses have multiple animal reservoirs (domestic and wild), making infection prevention in humans especially difficult to achieve.
