Characterisation of lamina I anterolateral system neurons that express Cre in a Phox2a-Cre mouse line.

Sci Rep 2021 Sep 9;11(1):17912. Epub 2021 Sep 9.

Institute of Neuroscience and Psychology, College of Medical, Veterinary and Life Sciences, University of Glasgow, Glasgow, G12 8QQ, UK.

A recently developed Phox2a::Cre mouse line has been shown to capture anterolateral system (ALS) projection neurons. Here, we used this line to test whether Phox2a-positive cells represent a distinct subpopulation among lamina I ALS neurons. We show that virtually all lamina I Phox2a cells can be retrogradely labelled from injections targeted on the lateral parabrachial area (LPb), and that most of those in the cervical cord also belong to the spinothalamic tract.

Deep-Freezing Temperatures During Irradiation Preserves the Compressive Strength of Human Cortical Bone Allografts: A Cadaver Study.

Clin Orthop Relat Res 2021 Sep 6. Epub 2021 Sep 6.

Bone Bank, National Orthopaedic Centre of Excellence in Research and Learning, Kuala Lumpur, Malaysia.

Background: Gamma irradiation, which minimizes the risk of infectious disease transmission when human bone allograft is used, has been found to negatively affect its biomechanical properties. However, in those studies, the deep-freezing temperature during irradiation was not necessarily maintained during transportation and sterilization, which may have affected the findings. Prior reports have also suggested that controlled deep freezing may mitigate the detrimental effects of irradiation on the mechanical properties of bone allograft. Read More

Health vs. wealth: Employer, employee and policy-maker perspectives on occupational heat stress across multiple European industries.

Temperature (Austin) 2021 14;8(3):284-301. Epub 2020 Dec 14.

Department of Nutrition, Exercise and Sports, University of Copenhagen, Copenhagen, Denmark.

Successful implementation of cooling strategies obviously depends on identifying effective interventions, but in industrial settings, it is equally important to consider feasibility and economic viability. Many cooling interventions are available, but the decision processes affecting adoption by end-users are not well elucidated. We therefore arranged two series of meetings with stakeholders to identify knowledge gaps, receive feedback on proposed cooling interventions, and discuss factors affecting implementation of heat-health interventions.

Increased risk of chronic fatigue and hair loss following COVID-19 in individuals with hypohidrotic ectodermal dysplasia.

Orphanet J Rare Dis 2021 09 3;16(1):373. Epub 2021 Sep 3.

Department of Pediatrics, University Hospital Erlangen, University of Erlangen-Nürnberg, Loschgestr. 15, 91054, Erlangen, Germany.

Background: Hypohidrotic ectodermal dysplasia (HED) is a group of genodermatoses in which deficient ectodysplasin A signalling leads to maldevelopment of skin appendages, various eccrine glands, and teeth. Individuals with HED often have disrupted epithelial barriers and, therefore, were suspected to be more susceptible to coronavirus infection.

Methods: 56 households with at least one member who had coronavirus disease of 2019 (COVID-19) were enrolled in a longitudinal study to compare the course of illness, immune responses, and long-term consequences of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection in HED patients (n = 15, age 9-52 years) and control subjects of the same age group (n = 149).

Heat-Health Behavior Change During Summer 2020 in African American Alabama Residents.

Am J Public Health 2021 08;111(8):1443-1447

Suwei Wang and Julia M. Gohlke are with the Department of Population Health Sciences, Virginia Polytechnic Institute and State University, Blacksburg. Suwei Wang is also with the Translational Biology, Medicine, and Health Program, Virginia Polytechnic Institute and State University. Ethel Johnson is with the Central Alabama Community Health Improvement League, Camden. Sheila Tyson is with Friends of West End, Birmingham, AL.

To investigate how heat-health behaviors changed in summer 2020 compared with previous summers, our community-academic partnership conducted telephone surveys to collect data on cooling behaviors, safety concerns, and preferences for cooling alternatives for 101 participants living in Alabama. Participants indicating they would visit cooling centers declined from 23% in previous summers to 10% in summer 2020. The use of cooling centers and other public spaces may be less effective in reducing heat-related illness because of safety concerns amid the COVID-19 pandemic and police brutality. Read More

Ischemic hypoxic encephalopathy: The role of MRI of neonatal injury and medico-legal implication.

Forensic Sci Int 2021 Aug 20;327:110968. Epub 2021 Aug 20.

Department of Radiology, University of Palermo, Via del Vespro 129, 90127 Palermo, Italy.

Hypoxic ischemic encephalopathy is one of the major causes of neonatal death and neurological disability in the child, and represents the most common birth injury claim. Intrapartum asphyxia often leads to several long-term sequalae, such as cerebral palsy and/or developmental delay, epilepsy. Through the neuroimaging it's possible to identify and define the different lesioned pictures and provide useful elements to establish the moment in which the damage occurred; indeed, timing of injury is a key element in the legal arena.

Sensors (Basel) 2021 Aug 9;21(16). Epub 2021 Aug 9.

Department of Mechanical and Aerospace Engineering, Monash University, Wellington Rd, Clayton, VIC 3800, Australia.

High-density polyethylene geomembranes are employed as covers for the sewage treatment lagoons at Melbourne Water Corporation's Western Treatment Plant, to harvest the biogas produced during anaerobic degradation, which is then used to generate electricity. Due to its size, inspecting the cover for defects, particularly subsurface defects, can be challenging, as well as the potential for the underside of the membrane to come into contact with different substrates, viz. liquid sewage, scum (consolidated solid matter), and biogas.

A hybrid thermal management system for high power lithium-ion capacitors combining heat pipe with phase change materials.

Heliyon 2021 Aug 12;7(8):e07773. Epub 2021 Aug 12.

Battery Innovation Center, MOBI Research Group, Vrije Universiteit Brussel, Pleinlaan 2, 1050, Brussels, Belgium.

Lithium-ion capacitor (LiC) technology is an energy storage system (ESS) that combines the working mechanism of electric double-layer capacitors (EDLC) and lithium-ion batteries (LiB). When LiC is supposed to work under high power applications, the inevitable heat loss threatens the cell's performance and lifetime. Therefore, a proper thermal management system (TMS) can remove the generated heat of the LiC during high cycling conditions. Read More

Improved Micro-X-ray Fluorescence Confocal Imaging of Two-Dimensional Distribution of Arsenic Concentration in Cucumber Hypocotyls Using Synchrotron Radiation.

Anal Chem 2021 08 17;93(34):11660-11668. Epub 2021 Aug 17.

X-ray Microspectroscopy and Imaging Group (XMI), Department of Chemistry, Ghent University, Krijgslaan 281 S12, Ghent B-9000, Belgium.

An optimized micro-X-ray fluorescence confocal imaging (μXRF-CI) analytical method has been developed to determine the 2D distribution of elemental composition in small (1-3 mm) biological objects at a 10-20 μm spatial resolution. Plants take up chemical elements from soil, and the vascular system transports them toward shoots. In order to obtain biochemical information related to this biological process, 2D distributions of chemical elements in roots and in hypocotyls of cucumber plants were analyzed by synchrotron radiation based on micro-X-ray fluorescence computer tomography and μXRF-CI techniques.
