A state-of-the-art review of the current role of cardioprotective techniques in cardiac transplantation.

Interact Cardiovasc Thorac Surg 2021 May;32(5):683-694

Department of Cardiothoracic Surgery, Cork University Hospital, Cork, Ireland.


Objectives: The use of 'extended criteria' donor hearts and reconditioned hearts from donation after circulatory death has corresponded with an increase in primary graft dysfunction, with ischaemia-reperfusion injury being a major contributing factor in its pathogenesis. Limiting ischaemia-reperfusion injury through optimising donor heart preservation may significantly improve outcomes. We sought to review the literature to evaluate the evidence for this. Read More

The expression of mimecan in adrenal tissue plays a role in an organism's responses to stress.

Aging (Albany NY) 2021 May 10;13. Epub 2021 May 10.

The Core Laboratory in Medical Center of Clinical Research, Department of Molecular Diagnostic and Endocrinology, Shanghai Ninth People’s Hospital, State Key Laboratory of Medical Genomics, Shanghai Jiao tong University School of Medicine, Shanghai 200011, China.

Mimecan encodes a secretory protein that is secreted into the human serum as two mature proteins with molecular masses of 25 and 12 kDa. We found 12-kDa mimecan to be a novel satiety hormone mediated by the upregulation of the expression of interleukin (IL)-1β and IL-6 in the hypothalamus. Mimecan was found to be expressed in human pituitary corticotroph cells and was up-regulated by glucocorticoids, while the secretion of adrenocorticotropic hormone (ACTH) in pituitary corticotroph AtT-20 cells was induced by mimecan.

Thermal tolerance, safety margins and vulnerability of coastal species: Projected impact of climate change induced cold water variability in a temperate African region.

Mar Environ Res 2021 Apr 29;169:105346. Epub 2021 Apr 29.

South African Institute for Aquatic Biodiversity, Makhanda, 6140, South Africa; Department of Ichthyology and Fisheries Science, Rhodes University, Makhanda, 6140, South Africa.

Anthropogenic induced climate change is predicted to increase the thermal variability in coastal waters, which can have strong physiological effects on individuals and populations of marine ectotherms. The magnitude and direction of these thermal effects varies depending on species, life stage, biogeography, habitat and season. This study aimed to compare the thermal tolerance of a range of juvenile fish and adult macro-invertebrates from intertidal and estuarine habitats in a warm-temperate, thermally variable region on the south-east coast of South Africa.

LPS decreases CFTR open probability and mucociliary transport through generation of reactive oxygen species.

Redox Biol 2021 Apr 30;43:101998. Epub 2021 Apr 30.

Department of Otolaryngology Head & Neck Surgery, University of Alabama at Birmingham, Birmingham, AL, USA; Gregory Fleming James Cystic Fibrosis Research Center, University of Alabama at Birmingham, Birmingham, AL, USA. Electronic address:

Lipopolysaccharide (LPS) serves as the interface between gram-negative bacteria (GNB) and the innate immune response in respiratory epithelial cells (REC). Herein, we describe a novel biological role of LPS that permits GNB to persist in the respiratory tract through inducing CFTR and mucociliary dysfunction. LPS reduced cystic fibrosis transmembrane conductance regulater (CFTR)-mediated short-circuit current in mammalian REC in Ussing chambers and nearly abrogated CFTR single channel activity (defined as forskolin-activated Cl currents) in patch clamp studies, effects of which were blocked with toll-like receptor (TLR)-4 inhibitor.

Faculty of Mechanical, Maritime and Materials Engineering, Delft University of Technology, Delft, the Netherlands.

External human-machine interfaces (eHMIs) may be useful for communicating the intention of an automated vehicle (AV) to a pedestrian, but it is unclear which eHMI design is most effective. In a crowdsourced experiment, we examined the effects of (1) colour (red, green, cyan), (2) position (roof, bumper, windshield), (3) message (WALK, DON'T WALK, WILL STOP, WON'T STOP, light bar), (4) activation distance (35 or 50 m from the pedestrian), and (5) the presence of visual distraction in the environment, on pedestrians' perceived safety of crossing the road in front of yielding and non-yielding AVs. Participants (N = 1434) had to press a key when they felt safe to cross while watching a random 40 out of 276 videos of an approaching AV with eHMI. Read More
