    This paper describes the frequency and anatomical abnormalities and pathologies identified on the skeletal sample discovered in 2014, in the Aroneanu Monastery Necropolis of Iaşi (Iaşi County, Romania). According to archaeological information, the necropolis was used since the first half of the 16th century until the beginning of the 19th century. The osteological material, consisting of 79 skeletons (children, adolescents, adults, matures and seniles), originated from inhumation tombs and reburials. The distribution by sex and age categories indicates a higher male frequency as opposed to females, resulting in a higher masculinity index. Most skeletons were recorded in the maturus category (59.49%), followed by infans I and II (21.52%), adultus (11.39%), senilis (5.06%) and juvenis (2.53%). The abnormalities and pathologies were evaluated both separately, by sex, and for the entire sample. In the cranial segment (for the entire sample), the Wormian bones recorded the highest frequency (15.18%), followed by the metopic suture (3.79%), cranial trauma, cribra orbitalia (with equal incidence – 2.53%) and porotic hyperostosis (1.26%). In the postcranial segment, osteoarthritis is the most frequent (11.39%), followed by spina bifida occulta, sacralization and extra facets on the tibiotalar joint – with equal incidence (3.79%). Lower incidences were recorded for the supratrochlear foramen of the humerus and lumbarization (1.26% each). In the male series, the frequency of pathologies and abnormalities is higher compared to the female series. No pathologies and abnormalities were observed on the skeletons of children and adolescents

    Get PDF
    The Global Alliance for Genomics and Health (GA4GH) is developing a suite of coordinated standards for genomics for healthcare. The Phenopacket is a new GA4GH standard for sharing disease and phenotype information that characterizes an individual person, linking that individual to detailed phenotypic descriptions, genetic information, diagnoses, and treatments. A detailed example is presented that illustrates how to use the schema to represent the clinical course of a patient with retinoblastoma, including demographic information, the clinical diagnosis, phenotypic features and clinical measurements, an examination of the extirpated tumor, therapies, and the results of genomic analysis. The Phenopacket Schema, together with other GA4GH data and technical standards, will enable data exchange and provide a foundation for the computational analysis of disease and phenotype information to improve our ability to diagnose and conduct research on all types of disorders, including cancer and rare diseases

    In biology and biomedicine, relating phenotypic outcomes with genetic variation and environmental factors remains a challenge: patient phenotypes may not match known diseases, candidate variants may be in genes that haven\u27t been characterized, research organisms may not recapitulate human or veterinary diseases, environmental factors affecting disease outcomes are unknown or undocumented, and many resources must be queried to find potentially significant phenotypic associations. The Monarch Initiative (https://monarchinitiative.org) integrates information on genes, variants, genotypes, phenotypes and diseases in a variety of species, and allows powerful ontology-based search. We develop many widely adopted ontologies that together enable sophisticated computational analysis, mechanistic discovery and diagnostics of Mendelian diseases. Our algorithms and tools are widely used to identify animal models of human disease through phenotypic similarity, for differential diagnostics and to facilitate translational research. Launched in 2015, Monarch has grown with regards to data (new organisms, more sources, better modeling); new API and standards; ontologies (new Mondo unified disease ontology, improvements to ontologies such as HPO and uPheno); user interface (a redesigned website); and community development. Monarch data, algorithms and tools are being used and extended by resources such as GA4GH and NCATS Translator, among others, to aid mechanistic discovery and diagnostics

    The Human Phenotype Ontology in 2024: phenotypes around the world.

    Get PDF
    The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English. Since our last report, a total of 2239 new HPO terms and 49235 new HPO annotations were developed, many in collaboration with external groups in the fields of psychiatry, arthrogryposis, immunology and cardiology. The Medical Action Ontology (MAxO) is a new effort to model treatments and other measures taken for clinical management. Finally, the HPO consortium is contributing to efforts to integrate the HPO and the GA4GH Phenopacket Schema into electronic health records (EHRs) with the goal of more standardized and computable integration of rare disease data in EHRs

    GA4GH: International policies and standards for data sharing across genomic research and healthcare.

    Get PDF
    The Global Alliance for Genomics and Health (GA4GH) aims to accelerate biomedical advances by enabling the responsible sharing of clinical and genomic data through both harmonized data aggregation and federated approaches. The decreasing cost of genomic sequencing (along with other genome-wide molecular assays) and increasing evidence of its clinical utility will soon drive the generation of sequence data from tens of millions of humans, with increasing levels of diversity. In this perspective, we present the GA4GH strategies for addressing the major challenges of this data revolution. We describe the GA4GH organization, which is fueled by the development efforts of eight Work Streams and informed by the needs of 24 Driver Projects and other key stakeholders. We present the GA4GH suite of secure, interoperable technical standards and policy frameworks and review the current status of standards, their relevance to key domains of research and clinical care, and future plans of GA4GH. Broad international participation in building, adopting, and deploying GA4GH standards and frameworks will catalyze an unprecedented effort in data sharing that will be critical to advancing genomic medicine and ensuring that all populations can access its benefits

    Finishing the euchromatic sequence of the human genome

    Get PDF
    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Cancer-Associated Stemness and Epithelial-to-Mesenchymal Transition Signatures Related to Breast Invasive Carcinoma Prognostic

    Breast cancer is one of the most common oncological diseases in women, as its incidence is rapidly growing, rendering it unpredictable and causing more harm than ever before on an annual basis. Alterations of coding and noncoding genes are related to tumorigenesis and breast cancer progression. In this study, several key genes associated with epithelial-to-mesenchymal transition (EMT) and cancer stem cell (CSC) features were identified. EMT and CSCs are two key mechanisms responsible for self-renewal, differentiation, and self-protection, thus contributing to drug resistance. Therefore, understanding of the relationship between these processes may identify a therapeutic vulnerability that can be further exploited in clinical practice, and evaluate its correlation with overall survival rate. To determine expression levels of altered coding and noncoding genes, The Cancer Omics Atlas (TCOA) are used, and these data are overlapped with a list of CSCs and EMT-specific genes downloaded from NCBI. As a result, it is observed that CSCs are reciprocally related to EMT, thus identifying common signatures that allow for predicting the overall survival for breast cancer genes (BRCA). In fact, common CSCs and EMT signatures, represented by ALDH1A1, SFRP1, miR-139, miR-21, and miR-200c, are deemed useful as prognostic biomarkers for BRCA. Therefore, by mapping changes in gene expression across CSCs and EMT, suggesting a cross-talk between these two processes, we have been able to identify either the most common or specific genes or miRNA markers associated with overall survival rate. Thus, a better understanding of these mechanisms will lead to more effective treatment options

    New anthropological research on the urban population inhabiting the city of Iaşi during the medieval age. The necropolis of the Banu Church (16th-19th centuries)

    In this article, the authors present the results of a bioanthropological research conducted upon a small osteological series (67 skeletons) unearthed from the necropolis of the old Banu Church, called at the time “The Falling Asleep of the Virgin Mary” Church. According to the information provided by those in charge of the digging (Stela Cheptea, PhD and C.S.I archaeologist and her collaborators), the necropolis was used from the first half of the 16th century to the beginning of the 19th century. The unearthed osteological material is mostly derived from reinhumation tombs and includes 67 skeletons or skeletal remains, of which 18 children (0-14 years: approximately 27%), three adolescents (14-20 years: approximately 4%), two adults, 40 matures (approximately 60%) and four seniles. The average life span, both for the entire series (0-x years) and by gender (20-x years) is similar to that of the late medieval populations who inhabited the Central Moldavian Plateau. The analysis of the conformative and morphoscopic biometric features revealed typological elements which indicate a Dinaric-Mediterranean-Alpine background, with rare Nordoid or East-Europoid influences. The Alpine elements give a distinctive mark to this population group
