The study intervention was effective among participants with or without baseline depression symptoms.Comparison of Different Matrices as Potential Quality Control Samples for Neurochemica... |
BACKGROUND |
Assay-vendor independent quality control (QC) samples for neurochemical dementia diagnostics (NDD) biomarkers are so far commercially unavailable. This requires that NDD laboratories prepare their own QC samples, for example by pooling leftover cerebrospinal fluid (CSF) samples. |
OBJECTIVE |
To prepare and test alternative matrices for QC samples that could facilitate intra- and inter-laboratory QC of the NDD biomarkers. |
METHODS |
Three matrices were validated in this study: (A) human pooled CSF, (B) Aβ peptides spiked into human prediluted plasma, and (C) Aβ peptides spiked into solution of bovine serum albumin in phosphate-buffered saline. All matrices were tested also after supplementation with an antibacterial agent (sodium azide). We analyz... |
RESULTS |
NDD biomarkers turned out to be stable in almost all samples stored at the tested conditions for up to 14 days as well as in samples stored deep-frozen (at - 80°C) for up to one year. Sodium azide did not influence biomarker stability. Inter-center variability of the samples sent at room temperature (pooled CSF, freeze... |
CONCLUSION |
Our results suggest that it is possible to replace self-made, CSF-based QC samples with large-scale volumes of QC materials prepared with artificial peptides and matrices. This would greatly facilitate intra- and inter-laboratory QC schedules for NDD measurements.Activation of the aryl hydrocarbon receptor reveals dist... |

As the Prague Quadrennial of Performance Design and Space 2019 (PQ19) drew to a close, Australian designers, researchers and educators gathered to discuss the impact of PQ on our scenographic communities while querying the evolutions and challenges facing design |
practice. Australia’s vast geography made this event a unique opportunity to bring together leading experts from multiple states and capture contemporary perspectives. At the midpoint between the 2019 and 2023 gatherings ‐ a time of global pandemics, political unrest and educational |
transformation ‐ this article offers the outcomes of this roundtable as a unique snapshot of the state of design practice within Australia through the lens of the Quadrennial. The roundtable was themed around Australia’s presence at PQ19, the effects of PQ19 |
on those present and the ripples to be felt by those at home, and what attendance illuminated about current developments and concerns in practice, teaching and research. Led by practitioner-researchers Tessa Rixon and Madeline Taylor, the roundtable featured both the curators of Australia’s |
country and student exhibits; award-winning set, costume and lighting designers with diverse experiences from national opera to independent theatre; and educators and researchers from the nation’s top universities. The resulting discussion presents a unique perspective on the gaps and |
weaknesses in the design education, practice and research; first-hand insights on the challenges and opportunities available in both exhibiting and participating in the PQ; and the need to actively promote and privilege diverse voices and a multiplicity of representations in the process |
of claiming a ‘national’ scenographic identity. The roundtable was the first to capture multiple expert first-person Australian perspectives on the PQ while simultaneously contributing to the ongoing international discussion of performance design through the lens of artists, |
educators and researchers.The Usefulness of Monocyte-to-High Density Lipoprotein and Neutrophil-to-Lymphocyte Ratio in Diabetic Macular Edema Prediction and Early anti-VEGF Treatment Response |

It is taught that epinephrine is much less effective by hypodermic or intramuscular injection than by the intravenous route. These differences are due to the rate of absorption, and this in turn to the vasoconstriction (Sollmann 1 ). The unabsorbed epinephrine at the site of injection is apparently not destroyed, for t... |
Systolic performance depends on end-diastolic muscle fiber length, contractility, and afterload. Ventricular function curves are constructed using end-diastolic pressure instead of end-diastolic dimensions, on the assumption that end-diastolic pressure and end-diastolic dimensions (reflecting muscle fiber length) have ... |
