Innate T-cell-derived IL-17A/F protects from bleomycin-induced acute lung injury but not bleomycin or adenoviral TGF-β1-induced lung fibrosis in mice.

The pathobiology of IL-17 in lung fibrogenesis is controversial. Here we examined the role of IL-17A/F in bleomycin (BLM) and adenoviral TGF-β1-induced lung fibrosis in mice. In both experimental models, WT and IL17af mice showed increased collagen contents and remodeled lung architecture as assessed by histopathological examination, suggesting that IL-17A/F is dispensable for lung fibrogenesis.

Pain Medication and Pain Intensity Following Hip Fractures-Analyses Based on the ProFem Cohort Study.

Purpose: Pain is a common symptom following proximal femoral fractures (PFF), however, information on its treatment in terms of agents and type of use (scheduled vs. pro re nata [PRN]) is scarce. The main objective of this study was to examine pain medication regimens according to pain intensity following PFF.

Development of Fear of Falling after proximal femoral fracture.

Proximal femoral fracture is common in older people. Beyond a long recovery process and significant permanent functional limitations, older people often experience subsequent Fear of Falling. The phenomenon of Fear of Falling is not fully understood; qualitative research is underrepresented but can provide insights into the experience of those affected.

Spiking neural networks fine-tuning for brain image segmentation.

Introduction: The field of machine learning has undergone a significant transformation with the progress of deep artificial neural networks (ANNs) and the growing accessibility of annotated data. ANNs usually require substantial power and memory usage to achieve optimal performance. Spiking neural networks (SNNs) have recently emerged as a low-power alternative to ANNs due to their sparsity nature.

Preanalytical variables influencing the interpretation and reporting of biological tests on blood samples of living and deceased donors for human body materials.

With the present paper, the Working Group on Cells, Tissues and Organs and other experts of the Superior Health Council of Belgium aimed to provide stakeholders in material of human origin with advice on critical aspects of serological and nucleic acid test (NAT) testing, to improve virological safety of cell- and tissue and organ donation. The current paper focusses on a number of preanalytical variables which can be critical for any medical biology examination: (1) sampling related variables (type of samples, collection of the samples, volume of the sample, choice of specific tubes, identification of tubes), (2) variables related to transport, storage and processing of blood samples (transport, centrifugation and haemolysis, storage before and after centrifugation, use of serum versus plasma), (3) variables related to dilution (haemodilution, pooling of samples), and (4) test dependent variables (available tests and validation). Depending on the type of donor (deceased donor (heart-beating or non-heart beating) versus living donor (allogeneic, related, autologous), and the type of donated human material (cells, tissue or organs) additional factors can play a role: pre- and post-mortem sampling, conditions of sampling (e.
