Elastase was detectable in human OA synovial fluid and OA synovia which displayed histologically graded evidence of synovitis. Bioinformatic analyses demonstrated that, compared with other tissues, control cartilage exhibited remarkably high transcript levels of the major elastase inhibitor, (AAT) alpha-1 antitrypsin (gene name SERPINA1), but these were reduced in OA. AAT was located predominantly in superficial cartilage zones, and staining enhanced in regions of cartilage damage. Finally, active MMP-13 specifically inactivated AAT by removal of the serine proteinase cleavage/inhibition site. Taken together, this study identifies elastase as a novel activator of pro-MMP-13 that has relevance for cartilage collagen destruction in OA patients with synovitis.Despite their suitability for studying evolution, many conifer species have large and repetitive giga-genomes (16-31 Gbp) that create hurdles to producing high coverage SNP data sets that capture diversity from across the entirety of the genome. Due in part to multiple ancient whole genome duplication events, gene family expansion and subsequent evolution within Pinaceae, false diversity from the misalignment of paralog copies creates further challenges in accurately and reproducibly inferring evolutionary history from sequence data. Here, we leverage the cost-saving benefits of pool-seq and exome-capture to discover SNPs in two conifer species, Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco, Pinaceae) and jack pine (Pinus banksiana Lamb., Pinaceae). We show, using minimal baseline filtering, that allele frequencies estimated from pooled individuals show a strong, positive correlation with those estimated by sequencing the same population as individuals (r > .948), on par with such comparisons made in model organisms. Further, we highlight the utility of haploid megagametophyte tissue for identifying sites that are probably due to misaligned paralogs. Together with additional minor filtering, we show that it is possible to remove many of the loci with large frequency estimate discrepancies between individual and pooled sequencing approaches, improving the correlation further (r > .973). Our work addresses bioinformatic challenges in non-model organisms with large and complex genomes, highlights the use of megagametophyte tissue for the identification of paralogous artefacts, and suggests the combination of pool-seq and exome capture to be robust for further evolutionary hypothesis testing in these systems.In a recent viewpoint commentary, McNulty et al. (2021) make the compelling case for removing eponymous terms from the anatomy classroom. Their argument is two-fold (1) the terms themselves are not descriptive of the anatomy and therefore increase the cognitive load of learners in a subject that already results in high cognitive loads; and (2) eponyms are often attributed erroneously, and the non-inclusive history of anatomy as a discipline means that eponyms are disproportionately attributed to white men, even when it is known that they were not the first to document or discover an anatomical structure. These two arguments alone are compelling enough to warrant considerable and thoughtful discussion about the continued use of eponyms in the anatomy classroom, and by extension in the anatomy literature.High levels of stress at work may have serious consequences for employee functioning and mental health. By providing employees with an easily accessible instrument to regularly evaluate stressors and resources, employee self-monitoring and guidance to support can be accommodated. We evaluated an online self-monitoring tool Brief Assessment of Stress and Energy (BASE). PF-04620110 in vitro Through their organization, 139 railway emergency services employees were invited to complete BASE and six wellbeing measures. We assessed BASE in two ways using multiple regression analysis (N = 102, 73.4%), as well as by telephone follow-up interviews during which experts and respondents evaluated the BASE outcome (N = 67, 65.7%). Explained variances of BASE on the six wellbeing measures ranged between 26.6% and 49.9%. Telephone interviews confirmed the BASE outcome. The results indicate that BASE is associated with several measures of wellbeing and accurately refers respondents to counseling. This study shows that BASE is a promising instrument to encourage employees to self-monitor stressors and resources and identify those who need counseling.The modern definition of enzymology is synonymous with the Michaelis-Menten equation instituted by Leonor Michaelis and Maud Menten. Most textbooks, or chapters within, discussing enzymology start with the derivation of the equation under the assumption of rapid equilibrium (as done by Michaelis-Menten) or steady state (as modified by Briggs and Haldane) conditions to highlight the importance of this equation as the bedrock on which interpretation of enzyme kinetic results is dependent. However, few textbooks or monographs take the effort of placing the equation within its right historical context and discuss the assumptions that have gone into its institution. This guide will dwell on these in substantial detail. Further, this guide will attempt to instil a sense of appreciation for the mathematical curve rectangular hyperbola, its unique attributes and how ubiquitous the curve is in biological systems. To conclude, this guide will discuss the limitations of the equation, and the method it embodies, and trace the journey of how investigators are attempting to move beyond the steady-state approach and the Michaelis-Menten equation into full progress curve, pre-steady state and single-turnover kinetic analysis to obtain greater insights into enzyme kinetics and catalysis.Chicory (Cichorium intybus var. sativum) is an industrial crop species cultivated for the production of a fructose polymer inulin, which is used as a low-calorie sweetener and prebiotic. Besides, inulin chicory taproots also accumulate sesquiterpene lactones (STLs). These are bitter tasting compounds, which need to be removed during inulin extraction, resulting in additional costs. In this work, we describe chicory lines where STL accumulation is almost completely eliminated. Genome editing using the CRISPR/Cas9 system was used to inactivate four genes that encode the enzyme that performs the first dedicated step in STL synthesis, germacrene A synthase (CiGAS). Chicory lines were obtained that carried null mutations in all four CiGAS genes. Lines lacking functional CiGAS alleles showed a normal phenotype upon greenhouse cultivation and show nearly complete elimination of the STL synthesis in the roots. It was shown that the reduction in STLs could be attributed to mutations in genetically linked copies of the CiGAS-short gene and not the CiGAS-long gene, which is relevant for breeding the trait into other cultivars.
