This repository contains an addendum to our previous paper on Oxford Nanopore basecalling: Wick RR, Judd LM, Holt KE. Performance of neural network basecalling tools for Oxford Nanopore sequencing. Genome Biology. 2019;20(1):129. It was motivated by two main questions. First, there have been...
The expression level of ORAI2 mRNA was higher in classical and mesenchymal types as described in a certain study [94]. ORAI2 has a prominent role in epithelial mesenchymal transition in both types of GBM and was found to correlate with self-regenerating features of stem cells. SOCE compound...
The adaptive immune response to influenza virus infection is multifaceted and complex, involving antibody and cellular responses at both systemic and mucosal levels. Immune responses to natural infection with influenza virus in humans are relatively broa
Each type of protein has a particular three-dimensional structure, which is determined by the order of the amino acids in its polypeptide chain. A protein’ s structure begins with its amino acid sequence, which is thus considered its primary structure. The next level of the organization include...
On the basis of our predictive statistical models, there were an estimated 4·95 million (3·62–6·57) deaths associated with bacterial AMR in 2019, including 1·27 million (95% UI 0·911–1·71) deaths attributable to bacterial AMR. At the regional level, we estimated the all-age dea...
Mood and anxiety disorders are frequent in the elderly and increase the risk of frailty. This study aimed to identify novel biomarkers of major depressive
Predatory bacteria feed upon other bacteria in various environments. Bdellovibrio exovorus is an obligate epibiotic predator that attaches on the prey cell surface, where it grows and proliferates. Although the mechanisms allowing feeding through the pre
(e.g., zebrafish examined here) has been repurposed to strictly facilitate buoyancy or act as a sensory organ7. Our cell type-level transcriptome analysis suggests that: (1) despite more than 400 million years of evolution, there is broad homology between the swim bladder of ray-finned ...
