KinOath Kinship Archiver Version 1.4

This talk will introduce a new tool for Humanities research, in particular Ethnology, Linguistics, Law, History, but also Genetics and Archiving. This tool is KinOath Kinship Archiver which is an application for collecting and analysing kinship data. It is designed to be flexible and culturally nonspecific, which is important to prevent extraneous concepts being imposed onto the data being recorded. The kinship data can be linked to external resources such as archive data. Graphical representation of the data is a key feature, it produces publishable quality diagrams that can be exported to SVG, PDF and JPG formats. Data can be imported from GEDCOM, CSV and TIP files. Data can be exported into CSV format, with additional formats becoming available as plugins. KinOath provides very flexible data fields for each individual / entity recorded in the kinship data, this is combined with customisable relation types, customisable symbols and customisable kin types. This means, for example, that any number of genders and kinship relations can be defined and represented on a diagram. The most common format, GEDCOM (Family History Department, 1999), can be imported into KinOath. However this GEDCOM format exhibits cultural specificities because it has a predetermined set of kinship types, genders and initiation ceremonies. We know that there is a wider array of kinship types (e.g. suckling relations (Altorki, 1980)) and genders (e.g. the Māhū of Hawaiʻi (Matzner, 2001)). There are also initiation ceremonies beyond the Christian and Jewish ceremonies that are predefined in GEDCOM. However once this data is imported, all the flexibility of KinOath will be available. KinOath has project based diagrams and freeform diagrams. Freeform diagrams are like a quick sketch; while project diagrams each have a database of kinship data which can be shared across multiple diagrams. Project based diagrams also allow kin type string queries, such that individuals to be found based on their relations to others. Individuals in a project diagram can be duplicated and merged, which can be useful, for example, in correcting data, or merging multiple data sets where some individuals overlap. In freeform diagrams kin terms can be defined with kin type strings and shown on the diagram, organised in groups, imported and exported. In the future it will be possible to overlay these kin terms onto project diagrams. In order to perform statistical analysis, the kinship data for each project or freeform diagram can be exported for use in R or SPSS. This combined with queries based on kin types and other search parameters, provides great potential in the analysis of both the kin data and the archive data that has been recorded. The intended users of Kinoath are any researchers that collect data in a context of social relations. Kinship data is often not systematically included in the metadata of archives, however these kin relations provide a context that enriches that archived data. KinOath is in active development and new features are regularly being added. The plugin framework that KinOath shares with Arbil has made it possible for external developers to add features.

Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass $M>70$ $M_\odot$) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities $0 < e \leq 0.3$ at $0.33$ Gpc$^{-3}$ yr$^{-1}$ at 90\% confidence level.Comment: 24 pages, 5 figure

Effect of methotrexate on bone and wound healing

Introduction: Methotrexate (MTX) is one of the most commonly used disease modifying drugs administered for wide spectrum of conditions. Through the expansion of the indications of MTX use, an increasing number of patients nowadays attend orthopaedic departments receiving this pharmacological agent. The aim of this manuscript is to present our current understanding on the effect of MTX on bone and wound healing. Areas covered: The authors offer a comprehensive review of the existing literature on the experimental and clinical studies analysing the effect of MTX on bone and wound healing. The authors also analyse the available literature and describe the incidence of complications after elective orthopaedic surgery in patients receiving MTX. Expert opinion: The available experimental data and clinical evidence are rather inadequate to allow any safe scientific conclusions on the effect of MTX on bone healing. Regarding wound healing, in vitro and experimental animal studies suggest that MTX can adversely affect wound healing, whilst the clinical studies show that lose-dose MTX is safe and does not affect the incidence of postoperative wound complications

European genetic study on rheumatoid arthritis: is there a linkage of the interleukin-1 (IL-1), IL-10 or IL-4 genes to RA?

The genetic predisposition for rheumatoid arthritis (RA) is only partly explained by the HLA locus and most genetic factors involved in the susceptibility (and/or severity) of the disease await further identification. The first European genome scan in RA families provided suggestive evidence for linkage with a region (3.1/3q13) on chromosome 3, but many other potential RA susceptibility genes have yet to be analysed. Aims. To perform a linkage analysis with microsatellite markers located in the vicinity of the interleukin-1 (IL-1) gene superfamily, the IL-10 gene and the IL-4 gene cluster which might be considered putative candidate loci for RA. Methods. 107 Caucasoid European RA sibpairs from 90 nuclear families were genotyped for markers flanking the genes for the IL-1 superfamily, IL-10 and the IL-4 gene cluster. Linkage analysis based on the identity by descent (IBD) in affected siblings was analysed with the program SIBPALNA. Affected sibpairs were stratified according to the identity by state (IBS) for three markers in the HLA region (DRB1 oligotyping, D6S276 and TNFa microsatellites) and to the presence/absence of erosive disease on X-ray examination. Results. Analysis of the whole family set showed an excess of allele sharing for markers of the IL-1 gene cluster (IBD 60%; P = 0.012) but not for IL-10 or IL-4. After stratification, the evidence of linkage to IL-1 was restricted to HLA concordant sibpairs (n = 32; IBD 70%; P = 0.006). Some evidence of linkage to IL-10 was also observed in HLA concordant sibpairs (IBD 66%; P = 0.03) and in sibpairs with erosive disease (n = 61; IBD 62%; P = 0.02). Conclusions. We found suggestive evidence of linkage of RA to the IL-1 locus. The increased linkage to IL-1 and IL-10 in HLA-identical sibs suggests a possible interaction between these cytokines and the HLA loci. Moreover IL-10 could interact with HLA factors in predisposing to erosive disease. These results need to be tested in additional families for consistency and replication

Observation of Gravitational Waves from the Coalescence of a 2.5−4.5 M⊙2.5-4.5~M_\odot Compact Object and a Neutron Star

International audienceWe report the observation of a coalescing compact binary with component masses $2.5-4.5~M_\odot$ and $1.2-2.0~M_\odot$ (all measurements quoted at the 90% credible level). The gravitational-wave signal GW230529_181500 was observed during the fourth observing run of the LIGO-Virgo-KAGRA detector network on 2023 May 29 by the LIGO Livingston Observatory. The primary component of the source has a mass less than $5~M_\odot$ at 99% credibility. We cannot definitively determine from gravitational-wave data alone whether either component of the source is a neutron star or a black hole. However, given existing estimates of the maximum neutron star mass, we find the most probable interpretation of the source to be the coalescence of a neutron star with a black hole that has a mass between the most massive neutron stars and the least massive black holes observed in the Galaxy. We estimate a merger rate density of $55^{+127}_{-47}~\text{Gpc}^{-3}\,\text{yr}^{-1}$ for compact binary coalescences with properties similar to the source of GW230529_181500; assuming that the source is a neutron star-black hole merger, GW230529_181500-like sources constitute about 60% of the total merger rate inferred for neutron star-black hole coalescences. The discovery of this system implies an increase in the expected rate of neutron star-black hole mergers with electromagnetic counterparts and provides further evidence for compact objects existing within the purported lower mass gap
