This research has never been conducted simultaneously.

Synthetic Human Embryos, Embryo Models and Embryo-like Structures in Islam

ABSTRACT A major breakthrough in developmental biology is the ex vivo generation of synthetic human embryos from stem cells. A comprehensive, in-depth bioethical analysis from a Sunni Islamic perspective reveals that the reproductive applications of synthetic human embryos contravene Islamic precepts of preserving lineage integrity (Hifz al-Nasl) due to disruption and confusion of kinship and familial relationships, similar to human cloning with somatic cell nuclear transfer. However, their non-reproductive applications in generating replacement tissues/organs, serving as in vitro experimental models of human development and disease, and testing platforms for evaluating pharmaceuticals and biomedical devices appear to align with Islamic principles.

Teaching as Family Life Educators in Collegiate Settings: The Application of Family Science Theories from Systemic and Chronological Perspectives

Family Science is an exciting field which offers a multitude of career pathways, including Family Life Educator (FLE) and the Certified Family Life Educator (CFLE) credential. In this article, I will discuss how, as a Family Life Educator in a university setting, I employ Bronfenbrenner's bioecological model of human development (Bronfenbrenner & Morris, 2006), Elder's (1998) life course perspective, and the concept of intersectionality in teaching family science courses. The article will conclude with discussions of the strengths, limitations, and lessons learned.

A Facile, Transfection-Free Approach to siRNA Delivery in In Vitro 3D Spheroid Models.

Cell culture has long been essential for preclinical modeling of human development and disease. However, conventional two-dimensional (2D) cell culture fails to faithfully model the complexity found in vivo, and novel drug candidates that show promising results in 2D models often do not translate to the clinic. More recently, three-dimensional (3D) cell culture models have gained popularity owing to their greater physiological relevance to in vivo biology. In particular, 3D spheroid models are becoming widely used due to their ability to mimic solid tumors, both in architecture and gradation of nutrients distributed from the outer, proliferative layers into the inner, quiescent layers of cells. Similar to in vivo tumors, cell lines grown in 3D spheroid models tend to be more resistant to antitumor drug treatments than their 2D cultured counterparts, though distinct signaling pathways and gene targets conferring this resistance have yet to be fully explored. RNA interference (RNAi) is an effective tool to elucidate gene function and discover novel druggable targets in 2D models; however, only a few studies have successfully performed RNAi in complex 3D models to date. Here, we demonstrate efficient RNAi-mediated knockdown using "transfection-free" Dharmacon Accell siRNAs in three spheroid culture models, in the presence or absence of the extracellular matrix. This methodology has the potential to be scaled up for complex arrayed screening experiments, which may aid in the identification of novel druggable targets with greater clinical relevance than those identified in 2D experiments. © 2024 Dharmacon, Inc.

MILESTONES IN THE DEVELOPMENT OF ORGANIZATIONAL MODELS BASED ON THE THEORY OF SPIRAL DYNAMICS

The article examines the milestones of the development of the business environment through the prism of industrial revolutions and the theory of spiral dynamics of organizational development. The past influences the present. The present shapes the future. The world is a complex, interconnected whole that is difficult to represent and understand, especially regarding complex socio-economic processes and organizational systems, including enterprises. The first radical change began precisely with the agrarian revolution when people domesticated animals as a basis for the transition from gathering to agriculture. After the agrarian revolution, radical industrial changes began in the 18th century. The first industrial revolution (from the 1760s to the 1840s) - the invention of the steam engine and the construction of railways. The second industrial revolution (the end of the 19th and the beginning of the 20th century) - the emergence of mass production thanks to the invention of electricity and the introduction of the conveyor. The third industrial revolution, from the 1960s, - was the emergence of semiconductors and their use in large electronic computing machines, personal computers, and the Internet. The fourth industrial revolution began at the beginning of the 21st century and is characterized by the emergence of "smart enterprises". The content and essential components of these periods imposed and imposed their understanding on the development of organizational models and the way of interaction between stakeholders and the economic entities themselves, which arose at the later stages of development and are developing under the influence of global business trends. Deepening the understanding of the nature of modern approaches in management aimed at the development of organizational systems allows turning to the past and investigating issues of organizational models on the way of the history of human development based on the theory of spiral dynamics (Don et al.), which is based on a dynamic model of human development and evolution of her consciousness, change of fundamental values. So, from the standpoint of the concept of systemic perfection of a business organization, based on the theory of spiral dynamics, its consideration can be started in the system-wide understanding of the system state, which corresponds to a greater extent to the content of perfection - from the orange stage and more/less corresponds to the current trends of the fourth industrial revolution. A significant strategic gap occurs based on the mismatch between the stage of development according to the milestones of industrial revolutions and the organization's current state in relation to the theory of spiral dynamics. For example, a red organization that functions in the fourth industrial revolution era. Management of changes in paradigms of thinking is the art of management.

Retinoic acid induces human gastruloids with posterior embryo-like structures

Gastruloids are a powerful in vitro model of early human development. However, although elongated and composed of all three germ layers, human gastruloids do not morphologically resemble post-implantation human embryos. Here we show that an early pulse of retinoic acid (RA), together with later Matrigel, robustly induces human gastruloids with posterior embryo-like morphological structures, including a neural tube flanked by segmented somites and diverse cell types, including neural crest, neural progenitors, renal progenitors and myocytes. Through in silico staging based on single-cell RNA sequencing, we find that human RA-gastruloids progress further than other human or mouse embryo models, aligning to E9.5 mouse and CS11 cynomolgus monkey embryos. We leverage chemical and genetic perturbations of RA-gastruloids to confirm that WNT and BMP signalling regulate somite formation and neural tube length in the human context, while transcription factors TBX6 and PAX3 underpin presomitic mesoderm and neural crest, respectively. Looking forward, RA-gastruloids are a robust, scalable model for decoding early human embryogenesis.

A brief chronicle of research on human pluripotent stem cells.

Today, human pluripotent stem cell technologies find widespread application across biomedical research, as models for early human development, as platforms for functional human genomics, as tools for the study of disease, drug screening and toxicology, and as a renewable source of cellular therapeutics for a range of intractable diseases. The foundations of this human pluripotent stem cell revolution rest on advances in a wide range of disciplines, including cancer biology, assisted reproduction, cell culture and organoid technology, somatic cell nuclear transfer, primate embryology, single-cell biology, and gene editing. This review surveys the slow emergence of the study of human pluripotency and the exponential growth of the field during the past several decades.

Risk patterns of bullying perpetration and victimization among children

ObjectivesThis study uses the bioecological model of human development and person-centered methods to describe the underlying patterns of risk and their association with bullying perpetration and victimization among U.S. children. MethodsUsing the National Survey of Children's Health, this study (n = 7319) explored the underlying patterns of risks across six domains (i.e., individual, family, school, neighborhood, economic, and socio-cultural) associated with bullying perpetration and victimization among U.S. elementary school children. ResultsLatent Class Analysis uncovered four patterns of risks. The low risks group (72.4%) showed the lowest rates of bullying perpetration (24.6%) and victimization (57.2%). The individual and environmental risks group (15.3%) presented moderate levels of bullying perpetration (31.8%) and victimization (67.1%). The family risks group (8.3%) showed moderate levels of bullying perpetration (35.9%) and victimization (66.0%). High risks group (4.0%) presented exceptionally high rates of bullying perpetration (59.1%) and victimization (87.3%). ConclusionResults suggest rates of bullying perpetration and victimization differed across the four patterns of risks. Understanding the sources of risk may be critical to alleviate bullying perpetration and victimization among children. ImplicationFindings suggest that child bullying should be approached with customized treatment considering their pattern of risk exposure.

A single-cell chromatin accessibility dataset of human primed and naïve pluripotent stem cell-derived teratoma

Teratoma, due to its remarkable ability to differentiate into multiple cell lineages, is a valuable model for studying human embryonic development. The similarity of the gene expression and chromatin accessibility patterns in these cells to those observed in vivo further underscores its potential as a research tool. Notably, teratomas derived from human naïve (pre-implantation epiblast-like) pluripotent stem cells (PSCs) have larger embryonic cell diversity and contain extraembryonic lineages, making them more suitable to study developmental processes. However, the cell type-specific epigenetic profiles of naïve PSC teratomas have not been yet characterized. Using single-cell assay for transposase-accessible chromatin sequencing (scATAC-seq), we analyzed 66,384 cell profiles from five teratomas derived from human naïve PSCs and their post-implantation epiblast-like (primed) counterparts. We observed 17 distinct cell types from both embryonic and extraembryonic lineages, resembling the corresponding cell types in human fetal tissues. Additionally, we identified key transcription factors specific to different cell types. Our dataset provides a resource for investigating gene regulatory programs in a relevant model of human embryonic development.

Understanding Left-Behind Places in a Contrastive Approach

Abstract How are left-behind places in a country compared to other types of places in an Eastern European country? A typology of local human development is designed and tested for the case of the Romanian society. The United Nations model of human development (structured by the three dimensions of education, economic development and health) is adapted to the local level and two contrasting measures are designed – an index and a typology of local human development. The typology resulted from a cluster analysis. It is validated by bi-variate and multivariate analysis (multinomial regression). High emigration rates, irrespective of the destination, do not bring lower development to the local origin in Romania: the destination of migration counts. There is a higher probability, in 2018, of left-behindness in localities with a higher number of emigrants to Italy in the years preceding 2011. Human development is highly differentiated by destination countries of emigration and by historical subregions. It is especially for such contexts that the quantitative approach could be misleading. Public policy targets could be better identified if qualitative and quantitative approaches are simultaneously used. The proposed approach could be adopted by keeping the same dimensions and measuring them by available and appropriate indicators.

Dynamic models of human development and concepts of the individual

Stem cells can be coaxed to self-organize into dynamic models of human development and early embryo formation. Despite their scientific promise, might widespread use of these technologies alter people's beliefs about what it means to be a human individual? Attention to some important philosophical distinctions may help navigate our thinking.

Biomechanical Analysis of Orbital Development: A Finite Element Analysis by an Experimentally Validated Model.

Constructing orbital finite element models capable of simulating the development process and analyzing the biomechanical mechanism. Four normal orbits from 1-month-old New Zealand white rabbits were used in this study. Toshiba Aquilion Prime was used to determine the computed tomography scan and direct orbital pressure manometry using an improved manometer based on the TSD104 pressure sensor transducer. The finite element analysis was conducted using the ANSYS Workbench platform. The biomechanics of each orbital wall improved to varying degrees as the rabbit orbit grew and developed. The von Mises stress in both rabbits initially concentrated at the lower edge of the posterior orbital wall, expanded to the entire orbit, and ultimately became more significant in the biomechanics of the region that consisted of the posterior orbital and superior orbital walls. During the expansion phase, the biomechanics of both rabbits gradually developed from the nasal side to the occipital side for radial displacement. It is evident that the finite element model is a good fit for simulating the physiological development of the rabbit orbit. The maximum radial displacement and maximum von Mises stress appeared 2 intermissions during the development of the orbit, at about 50 to 60 days and 80 to 90 days. This study establishes a theoretical foundation for the creation of a biomechanical model of human orbital development by offering the first finite element model to simulate orbital development and analyze the biomechanical mechanism of orbital pressure on orbital development.

HPSC-Derived Astrocytes at the Forefront of Translational Applications in Neurological Disorders.

Astrocytes, the most abundant glial cell type in the brain, play crucial roles in maintaining homeostasis within the central nervous system (CNS). Impairment or abnormalities of typical astrocyte functions in the CNS serve as a causative or contributing factor in numerous neurodevelopmental, neurodegenerative, and neuropsychiatric disorders. Currently, disease-modeling and drug-screening approaches, primarily focused on human astrocytes, rely on human pluripotent stem cell (hPSC)-derived astrocytes. However, it is important to acknowledge that these hPSC-derived astrocytes exhibit notable differences across studies and when compared to their in vivo counterparts. These differences may potentially compromise translational outcomes if not carefully accounted for. This review aims to explore state-of-the-art in vitro models of human astrocyte development, focusing on the developmental processes, functional maturity, and technical aspects of various hPSC-derived astrocyte differentiation protocols. Additionally, it summarizes their successful application in modeling neurological disorders. The discussion extends to recent advancements in the large-scale production of human astrocytes and their application in developing high-throughput assays conducive to therapeutic drug discovery.

From Divorce to Remarriage: Understanding the Experience of Remarried Women in a Collectivist Society

ABSTRACT This study explores the subjective experiences of remarriage among five divorced Malay Muslim women with children from their first marriages, who have since remarried. Using semi-structured interviews, their remarriage journeys were analyzed through Interpretative Phenomenological Analysis. Four main themes – internal process, adjusting to a new marriage, relationships with others, and marital satisfaction – along with ten sub-themes were identified. These themes encompass emotional struggles post-divorce, acceptance of reality and fate, mixed feelings pre-remarriage, decision-making in remarriage, dynamics within couple roles and interactions, and relationships with children, in-laws, extended family, and ex-spouses, culminating in the joy and gratitude experienced in their current marriages. This study was informed by Carter & McGoldrick’s Remarried Family Formation Framework and Bronfenbrenner’s Bioecological Model of Human Development, which together provided a robust theoretical lens for understanding the complexities of remarriage in a culturally rich setting. The findings offer significant implications for practitioners working with remarried individuals and highlight areas for future research.

Using Trentham’s principle of inverse consistency to vet models of human development for use in Christian educator preparation programs

This article aims to utilize Trentham’s Inverse Consistency Protocol (ICP) to appraise human development models for use within Christian educator preparation programs. The authors propose that the ICP can be applied to any secular paradigms to discern potential areas of inconsistency with an institution’s faith tradition. To illustrate application of the ICP in this way, Vygotsky’s Zone of Proximal Development (ZPD) model was provided as an example of one model of human development that is widely taught in educator preparation programs. The ZPD model was submitted through the four-step inverse consistency protocol. Findings suggest that ICP is a reflective tool for engaging with the social sciences with integrity after protocol results indicated that ZPD is an appropriate model for use by Christian educators when used responsibly. Implications for extended use of ICP are discussed.

Primitive macrophages induce sarcomeric maturation and functional enhancement of developing human cardiac microtissues via efferocytic pathways.

Yolk sac macrophages are the first to seed the developing heart, however we have no understanding of their roles in human heart development and function due to a lack of accessible tissue. Here, we bridge this gap by differentiating human embryonic stem cells (hESCs) into primitive LYVE1+ macrophages (hESC-macrophages) that stably engraft within contractile cardiac microtissues composed of hESC-cardiomyocytes and fibroblasts. Engraftment induces a human fetal cardiac macrophage gene program enriched in efferocytic pathways. Functionally, hESC-macrophages trigger cardiomyocyte sarcomeric protein maturation, enhance contractile force and improve relaxation kinetics. Mechanistically, hESC-macrophages engage in phosphatidylserine dependent ingestion of apoptotic cardiomyocyte cargo, which reduces microtissue stress, leading hESC-cardiomyocytes to more closely resemble early human fetal ventricular cardiomyocytes, both transcriptionally and metabolically. Inhibiting hESC-macrophage efferocytosis impairs sarcomeric protein maturation and reduces cardiac microtissue function. Taken together, macrophage-engineered human cardiac microtissues represent a considerably improved model for human heart development, and reveal a major beneficial role for human primitive macrophages in enhancing early cardiac tissue function.

The limitations of automatically generated curricula for continual learning.

In many applications, artificial neural networks are best trained for a task by following a curriculum, in which simpler concepts are learned before more complex ones. This curriculum can be hand-crafted by the engineer or optimised like other hyperparameters, by evaluating many curricula. However, this is computationally intensive and the hyperparameters are unlikely to generalise to new datasets. An attractive alternative, demonstrated in influential prior works, is that the network could choose its own curriculum by monitoring its learning. This would be particularly beneficial for continual learning, in which the network must learn from an environment that is changing over time, relevant both to practical applications and in the modelling of human development. In this paper we test the generality of this approach using a proof-of-principle model, training a network on two sequential tasks under static and continual conditions, and investigating both the benefits of a curriculum and the handicap induced by continuous learning. Additionally, we test a variety of prior task-switching metrics, and find that in some cases even in this simple scenario the a network is often unable to choose the optimal curriculum, as the benefits are sometimes only apparent with hindsight, at the end of training. We discuss the implications of the results for network engineering and models of human development.

The Virtual Child will "develop cancer" that we will subject to unlimited virtual clinical trials that pinpoint, predict, and prioritize potential new treatments, bringing forward the day when no child dies of cancer, giving each one the opportunity to lead a full and healthy life.

Abstract 4254: Genetically engineered human lung organoid models for lung cancer evolution study

Abstract Initial cellular events in a transitional period from normal to cancer cells, such as transcriptomic or epigenetic dynamics, are poorly understood. Observing these is more challenging than in cancer progression, especially for humans. Mapping this phenomenon in early cancer evolution is crucial, as we can identify targetable molecules to inhibit cancer development at the precancerous stage. Immortalized human cancer cell lines hardly capture these appropriately as they have lost usual cellular characteristics. Normal organoids harbor stem cells and their differentiated cells, reflecting the epithelial physiology of tissues, and are more suitable models for cancer evolution studies. To establish a human cancer development model in vitro, we genetically engineered normal human airway organoids derived from adult stem cells into small cell lung cancer (SCLC). We used CRISPR-Cas9 systems to induce non-homologous end-joining in both TP53 and RB1, the most frequently mutated genes of SCLC. First, we knocked out TP53 of the airway organoids, selected by Nutlin-3a, an MDM2 antagonist, for 3-4 weeks, demonstrating 88-89% editing efficiencies calculated from Sanger sequencing results. Most mutations were one base pair deletion or insertion, which induced frameshift mutation in TP53. They did not show a significant difference from wild-type organoids morphologically at bright-field microscopy. Subsequently, we targeted RB1 on TP53-/- airway organoids to induce SCLC. We used Palbociclib, a CDK4/6 inhibitor, to enrich the mutated cells. They had 67.1% efficiency, and 20.4% had a 7-base pair deletion mutation. In the initial period, they seemed to have similar shapes to TP53-/- organoids. Unexpectedly and interestingly, however, we noticed more rapidly proliferating and disorganized organoids disrupting their original round shapes appeared in 4-5 weeks. The cells were indiscriminately piled up on the airway organoids' apical and basolateral surfaces, indicating their malignant traits. Their chaotic proliferation represented the rapidly progressing clinical feature of SCLC with a median survival of 7-16 months with treatment. This is the first work constructing the SCLC development model from the normal human airway organoid. By sequentially single-cell sequencing this organoid model changing to tumorous condition, we can capture the multi-omics landscape during the initial evolution of SCLC.

Spirituality as a key asset in promoting positive youth development: Advances in research and practice

Spirituality is a universal human experience. Within the process of development, the role of spirituality as a developmental asset is understudied in general and especially within majority world contexts. In this article, we frame advances in spirituality research and practice with youth around three pillars: (a) theory, (b) measurement, and (c) research about and evaluations of positive youth development (PYD) programs in low- and middle-income countries. We place PYD programs as associated with dynamic, relational developmental systems (RDS)-based models of human development, describe spirituality and the “Big Three” features of effective PYD programs as aligning to promote thriving, and discuss spirituality as a strength, as a key asset, in the lives of youth. We discuss advances in developmental methods and measures for describing, explaining, and promoting spirituality and PYD and offer a case study that responds to a United States Agency for International Development call for action and evaluations of spirituality within the context of a PYD program in the majority world. Considerations for future research about spirituality and youth development are discussed.
