title: Comparative in vitro toxicity of different thermal spray particulates in human bronchial cells

description: Introduction: Thermal spray, in general, is a process that involves forcing a melted substance, such as metal or ceramic in the form of wire or powder, onto the surface of a targeted object to enhance its desired surface properties. In this paper, the melted substance is metal wire generated by an electric arc and forcibly coated on a rotary iron substrate using compressed air. This thermal process is referred to as double-wire arc thermal spray. The particles generated through these methods fall within the nanometer to micrometer agglomerate size range. There is concern regarding potential human health outcomes as these particles exhibit a similarity in particle morphology to welding fumes. Thermal spray wires with Zn (PMET540), Fe and Cr (PMET731), and Ni (PMET885) as primary metal compositions were used to generate particulate via an electric arc wire thermal spray generator for exposure to human bronchial cells (BEAS-2B) to examine comparative toxicity ranging from 0-200 µg/mL. Resulting cellular viability was assessed through live cell counts, and percent cytotoxicity was measured as a function of LDH release. Oxidative stress, genotoxicity, and alteration in Total Antioxidant Capacity were evaluated through DNA damage (COMET analysis) and antioxidant concentration at 0, 3.125, 25, and 100 µg/mL. Protein markers for Endothelin-1 (ET-1), Interleukin-6 (IL-6), and Interleukin-8 (IL-8) were also assessed to determine inflammation and endothelial alteration.

title: NanoSpotTM Collector for Aerosol Sample Collection for Direct Microscopy and Spectroscopy Analysis-Dataset

description: We describe design and characterization of an aerosol NanoSpotTM collector, designed for collection of airborne particles on a microscopy substrate for direct electron microscopy, optical microscopy, and laser spectroscopy analysis. The collector implements a water-based, laminar-flow, condensation growth technique, followed by impaction onto an optical/electron microscopy substrate or a transmission electron microscopy grid for direct analysis. The compact design employs three parallel growth tubes allowing a sampling flow rate of 1.2 L min-1. Each of the three growth tubes consists of three-temperature regions, for controlling the water vapor saturation profile and exit dew point. Following the droplet growth, the three streams merge into one flow and a converging nozzle enhances focusing of the grown droplets into a tight beam, prior to their final impaction on the warm surface of the collection substrate. A miniscule sample deposition area is attained for effective coupling with microscopic and spectroscopic analysis. Experiments were conducted for the acquisition of the size-dependent collection efficiency, the uniformity of the spot deposit, the surface density distribution of the collected particles, and the aerosol concentration effect on the triple-tube NanoSpotTM Collector. Particles as small as 7 nm could be activated and collected on the electron microscopy stub. A spot deposit of approximately 0.7-mm diameter is formed for particles over a broad particle diameter range. The collected particle samples were analyzed using electron microscopy and Raman spectroscopy for the acquisition of the particle spatial distribution, the spot sample uniformity, and the analyte concentration. Finally, the NanoSpotTM collector’s analytical measurement sensitivity for laser Raman analysis and the counting statistics for fiber count measurement using optical microscopy were calculated and were compared with those of the conventional aerosol sampling methods.

title: Persistence of SARS-CoV-2 on N95 filtering facepiece respirators: implications for reuse

description: In response to the shortage of N95® filtering facepiece respirators (FFRs) for healthcare workers during the COVID-19 pandemic, the Centers for Disease Control and Prevention (CDC) issued strategies for extended use and limited reuse of N95 FFRs to conserve supply. Previously worn N95 FFRs can serve as a source of pathogens, which can be transferred to the wearer while doffing and donning a respirator when practicing reuse. To reduce the risk of self-contamination when donning and doffing reused FFRs, the CDC suggested storing FFRs for five days between uses to allow for the decay of viable pathogens including SARS-CoV-2. This study assessed the persistence of the SARS-CoV-2 strain USA-WA1/2020 on N95 FFRs under controlled storage conditions for up to five days to inform the CDC guidance.

title: Evaluation of the fall protection of Type I industrial helmets

description: Type I industrial helmets have been widely used at construction sites 
and by manufacturers as “general purpose” safety helmets. The 
performance of Type I industrial helmets for fall protection is not 
required to be tested in standardized tests. Chin straps and suspension 
system adjustment mechanisms are two important components of a typical 
industrial helmet, but the effects of proper use of them on the 
protective performance of Type I helmets have not been evaluated. The 
current study was designed to analyze the fall protection performance of
 Type I industrial helmets and to evaluate if the use of a chin strap 
and the suspension system tightness have any effect on protection 
performance. Head impact tests were performed by letting an instrumented
 manikin free fall backwards, from a standing posture, so that the 
manikin would make head-first contact with a solid surface of two 
different materials (concrete and plywood-covered). The results showed 
that all four tested helmet models demonstrated excellent performances 
for fall protection compared to the control group without wearing 
helmets. The fall protection performance of the advanced helmet models 
was substantially better than the basic helmet models. However, the 
effects of the use of chin straps and suspension system tightness on the
 helmets’ fall protection performance were statistically not 
significant. The findings of our study provide information to help 
construction companies and manufacturers better manage the use of Type I
 helmets for fall protection, thereby reducing work-related traumatic 
brain injury risks.<br>

title: Inconsequential Role for Chemerin-Like Receptor 1 in a Manifestation of Ozone-Induced Lung Pathophysiology in Male Mice

description: Chemerin, a non-chemokine chemoattractant, and resolvin E1 (RvE1), a specialized pro-resolving lipid mediator, are endogenous ligands for chemerin-like receptor 1 (CMKLR1), a Gi/o protein-coupled receptor expressed by leukocytes and non-leukocytes. In mice, exogenous administration of chemerin or RvE1 diminishes the severity of lung inflammation and airway hyperresponsiveness (AHR) induced by antigen sensitization and challenge, which mimics phenotypic features of atopic asthma in humans. However, the contribution of chemerin or RvE1 to features of non-atopic asthma is unknown. Therefore, to indirectly assess if chemerin or RvE1 facilitates development of a non-atopic asthma phenotype, which includes AHR to acetyl-β-methylcholine chloride, lung hyperpermeability, airway epithelial cell desquamation, and lung inflammation, we quantified features of these sequelae in wild-type mice and mice failing to express CMKLR1 (CMKLR1-deficient mice) following cessation of acute inhalation exposure to either filtered room air or ozone, a criteria pollutant and non-atopic asthma stimulus.

title: SH0149657.10FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
