Evidence of hybrid speciation in the North American primroses Primula suffrutescens, P. parryi, P. rusbyi and P. angustifolia (Primulaceae)
No full textThe genetic structure of tetraploid (4x = 44) North American species of Primula subgenus Auriculastrum: P. suffrutescens,P. parryi, P. rusbyi, and P. angustifolia was analyzed at seven enzyme loci and compared with that of the related diploidP. cuneifolia and P. nipponica. The studied tetraploid species showed fixed or almost fixed heterozygosity at various loci,indicating a hybrid origin. About half of their alleles were shared with Cuneifolia taxa sampled, suggesting that they arose from crosses involving a maternal Cuneifolia-like ancestor. A preliminary survey of their possible paternal species, as inferred from their genotypes, was carried out among different Primula groups. Several paternal alleles expected were observed in subgenus Aleuritia, particularly among taxa of sect. Crystallophlomis (e.g., P. chionantha, P. minor, and P. nivalis xanthobasis). However, none of these taxa proved to be a suitable paternal species. Hybridization events that originated P. suffrutescens, P. parryi, P. rusbyi, and P. angustifolia presumably occurred during Pleistocene secondary contacts in Beringia and involved a maternalCuneifolia-like ancestor and at least two paternal species, for sect. Suffrutescens and Parryi, respectively. Further studies,involving a genetic survey of Aleuritia taxa from Siberia will be needed to detect such paternal species, if not extinct

Descriptive norms for 245 Italian idiomatic expressions
No full textAbstract The present study reports descriptive normative
measures for 245 Italian verbal idiomatic expressions. For
each of the idiomatic expressions the following variables are
reported: Length, Knowledge, Familiarity, Age of Acquisition,
Predictability, Syntactic flexibility, Literality and Compositionality.
Syntactic flexibility was assessed using five
syntactic operations: adverb insertion, adjective insertion, left
dislocation, passive and movement. The psycholinguistic
relevance of each dimension, their measures and the correlations
among them are provided and discussed. The databases
are freely available for down-loading from the Psychonomic
Society Web archive at www.psychonomic.org/archive/
Open source software for data collection from SDI-12 sensors connected to an Arduino microcontroller.
No full textThis document is open source software intended for the development of low-cost data acquisition and telemetry systems for geotechnical instrumentation applications. This software determines all addresses for active SDI-12 (serial digital interface 1,200 Baud) sensors connected to an Arduino microcontroller, and logs data from each sensor. SDI-12 sensors are commonly used for measuring matric suction, volumetric water content and temperature sensor.
TERMS OF USE:
The following sketch is to be considered open-source and is largely based on open-source example code from
https://github.com/EnviroDIY/Arduino-SDI-12.
Modifications have been made to combine a number of examples and tailor the code to geotechnical use.
Use of the following open-source code is encouraged to help in the construction of an open-source datalogger.
For any publications that arise from the use of this code, please cite this permanent link and associated journal paper at:

Ischemia‐modified albumin in rheumatic diseases: A systematic review and meta‐analysis
No full textAbstract Introduction The identification of novel, easily measurable disease biomarkers might enhance the diagnosis and management of patients with rheumatic diseases (RDs). We conducted a systematic review and meta‐analysis of ischemia‐modified albumin (IMA), a marker of oxidative stress, acidosis, and ischemia, in RD patients and healthy controls. Methods We searched PubMed, Web of Science, and Scopus from inception to January 15, 2024. The risk of bias and the certainty of evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist and GRADE, respectively. Results In 20 studies investigating a total of 1188 RD patients (mean age 45 years, 64% females) and 981 healthy controls (mean age 44 years, 66% females), RD patients had significantly higher IMA concentrations when compared to controls (standard mean difference, SMD = 0.50, 95% CI: 0.18−0.83, p = .003; I2 = 92.4%, p < .001; low certainty of evidence). In subgroup analysis, the pooled SMD was significantly different in studies investigating ankylosing spondylitis (p < .001), Behçet's disease (p < .001), and rheumatoid arthritis (p = .033), but not familial Mediterranean fever (p = .48). Further associations were observed between the pooled SMD and the broad classification of autoimmune and/or autoinflammatory diseases, the study country, and the method used to measure IMA. Conclusion Our study suggests that IMA is a promising biomarker of oxidative stress, acidosis, and ischemia, as it can effectively discriminate between patients with different types of RDs and healthy controls. Our results warrant confirmation in longitudinal studies of patients with different types of RDs and different ethnicities (PROSPERO registration number: CRD42024509126)
An Updated Systematic Review and Meta-Analysis of the Association between the De Ritis Ratio and Disease Severity and Mortality in Patients with COVID-19
No full textPatients with Coronavirus disease 2019 (COVID-19) often have elevations in markers of liver injury, particularly serum aspartate transaminase (AST) and alanine transaminase (ALT). Such alterations may affect the AST/ALT ratio (De Ritis ratio) and, potentially, clinical outcomes. We conducted an updated systematic review and meta-analysis of the association between the De Ritis ratio and COVID-19 severity and mortality in hospitalized patients. PubMed, Web of Science, and Scopus were searched between 1 December 2019 and 15 February 2023. The Joanna Briggs Institute Critical Appraisal Checklist and the Grading of Recommendations, Assessment, Development, and Evaluation were used to assess the risk of bias and the certainty of the evidence, respectively. Twenty-four studies were identified. The De Ritis ratio on admission was significantly higher in patients with severe disease and non-survivors vs. patients with non-severe disease and survivors (15 studies, weighted mean difference = 0.36, 95% CI 0.24 to 0.49, p p ˂ 0.001; nine studies). Similar results were observed using hazard ratios (2.36, 95% CI 1.17 to 4.79, p = 0.017; five studies). In six studies, the pooled area under the receiver operating characteristic curve was 0.677 (95% CI 0.612 to 0.743). In our systematic review and meta-analysis, higher De Ritis ratios were significantly associated with severe disease and mortality in COVID-19 patients. Therefore, the De Ritis ratio can be useful for early risk stratification and management in this patient group (PROSPERO registration number: CRD42023406916)
