  1. Regeneration of Hydra from aggregated cells.Alfred Gierer, S. Berking, H. Bode, C. N. David, K. Flick, G. Hansmann, H. Schaller & E. Trenkner - 1972 - Nature New Biology 239:98-101.
    • Aggregates of previously isolated cells of Hydra are capable, under suitable solvant conditions, of regeneration forming complete animals. In a first stage, ecto- and endodermal cells sort out, producing the bilayered hollow structure characteristic of Hydra tissue; thereafter, heads are formed (even if the original cell preparation contained no head cells), eventually leading to the separation of normal animals with head, body column and foot. Hydra appears to be the highest type of organism that allows for regeneration (...)

  2. Cognitive Regeneration and the Noetic Effects of Sin: Why Theology and Cognitive Science May not be Compatible.Lari Launonen - 2021 - European Journal for Philosophy of Religion 13 (3).
    Justin Barrett and Kelly James Clark have suggested that cognitive science of religion supports the existence of a god-faculty akin to sensus divinitatis. They propose that God may have given rise to the god-faculty via guided evolution. This suggestion raises two theological worries. First, our natural cognition seems to favor false god-beliefs over true ones. Second, it also makes us prone to tribalism. If God hates idolatry and moral evil, why would he give rise to mind with such biases? A (...)

  4. A theory of biological pattern formation.Alfred Gierer & Hans Meinhardt - 1972 - Kybernetik, Continued as Biological Cybernetics 12 (1):30 - 39.
    The paper addresses the formation of striking patterns within originally near-homogenous tissue, the process prototypical for embryology, and represented in particularly purist form by cut sections of hydra regenerating, by internal reorganisation of the pre-existing tissue, a complete animal with head and foot. The essential requirements are autocatalytic, self-enhancing activation, combined with inhibitory or depletion effects of wider range – “lateral inhibition”. Not only de-novo-pattern formation, but also well known, striking features of developmental regulation such as induction, inhibition, and proportion (...)

  5. Reorganization of a Spinal Motoneuron Nucleus following Autologous Nerve Graft in the Rat.Dieter M. Weinert - 2016 - Norderstedt, Deutschland: BoD.
    Autologous nerve grafts are steadily regarded as the method of choice for bridging the nerve gaps resulting after peripheral nerve lesions with substance defects. Microsurgical techniques and the perineurial suture of corresponding fascicles have improved the functional results following peripheral nerve graft. -/- However, regeneration success is often disappointing, despite the most thorough technique and expertise. The loss of spinal motoneurons associated with a nerve lesion and the growth of axon sprouts in inadequate endoneurial sheaths were held responsible as (...)

  6. Beyond Community: Inclusivity through Spatial Interventions.Asma Mehan, Krzysztof Nawratek & Farouq Tahar - 2022 - Writingplace: Journal for Architecture and Literature 1 (6):136-147.
    This article argues against the concept of integration as the main mechanism allowing various sociocultural groups to live together and instead proposes ‘radical inclusivity’ as a better, less oppressive model of a pluralistic society. Through analytical and reflective research on the non-cohesion-based approach to integration or inclusion, this article is devoted to examining the affordances and limitations of integration through various forms of spatial interventions. As an example, we will discuss the Ellesmere Green Project in Sheffield (UK) as a typical (...)

  7. Asylum, Credible Fear Tests, and Colonial Violence.Elena Ruíz & Ezgi Sertler - manuscript
    A credible fear test is an in-depth interview process given to undocumented people of any age arriving at a U.S. port of entry to determine qualification for asylum-seeking. Credible fear tests as a typical immigration procedure demonstrate not only what structural epistemic violence looks like but also how this violence lives in and through the design of asylum policy. Key terms of credible fear tests such as “significant possibility,” “evidence,” “consistency,” and “credibility” can never be neutral in the context of (...)

  8. Stem Cells and the Microenvironment: Reciprocity with Asymmetry in Regenerative Medicine.Militello Guglielmo & Bertolaso Marta - 2022 - Acta Biotheoretica 70 (4):1-27.
    Much of the current research in regenerative medicine concentrates on stem-cell therapy that exploits the regenerative capacities of stem cells when injected into different types of human tissues. Although new therapeutic paths have been opened up by induced pluripotent cells and human mesenchymal cells, the rate of success is still low and mainly due to the difficulties of managing cell proliferation and differentiation, giving rise to non-controlled stem cell differentiation that ultimately leads to cancer. Despite being still far from becoming (...)

    AN ATTEMPT to understand the role of dignity in human rights is worthwhile and challenging. Popularly referred to as a “constitutional principle”, “moral precept”, or a “supreme virtue”, dignity has allowed legal systems to adopt evolutionary and impactful practices concerning the welfare of human beings. Defined also as the precursor and basis to the various human rights defined and adopted, dignity continues to facilitate the integration of diverse interests and stakeholders within the framework of human rights thought and practice.

  10. A Guide to Kant’s Treatment of Grace.Pablo Muchnik & Lawrence Pasternack - 2017 - Con-Textos Kantianos 6:256-271.
    This Guide is designed to restore the theological background that informs Kant’s treatment of grace in Religion to its rightful place. This background is essential not only to understand the nature of Kant’s overall project in this book, namely, to determine the “association” or “union” between Christianity (as a historical faith) and rational religion, but also to dispel the impression of “internal contradictions” and conundrums” that contemporary interpreters associate with Kant’s treatment of grace and moral regeneration. That impression, we (...)

  11. Generation of Biological Patterns and Form: Some Physical, Mathematical and Logical Aspects.Alfred Gierer - 1981 - Progress in Biophysics and Molecular Biology 37 (1):1-48.
    While many different mechanisms contribute to the generation of spatial order in biological development, the formation of morphogenetic fields which in turn direct cell responses giving rise to pattern and form are of major importance and essential for embryogenesis and regeneration. Most likely the fields represent concentration patterns of substances produced by molecular kinetics. Short range autocatalytic activation in conjunction with longer range “lateral” inhibition or depletion effects is capable of generating such patterns (Gierer and Meinhardt, 1972). Non-linear reactions (...)

  12. Bare Land: Alienation as Deracination in Anna Tsing and John Steinbeck.Tim Christiaens - 2024 - In Re-imagining Class. pp. 257-277.
    In The Mushroom at the End of the World: On the Possibility of Life in Capitalist Ruins, Anna Lowenhaupt Tsing explains how bare land is formed. Capitalism produces ‘ruins’ by stripping living beings of the capacity to form their own ecological relations, a necessary condition for the reproduction of life. Contemporary capitalism alienates living beings from ecological relations, i.e. capitalism generates “the ability to stand alone, as if the entanglements of living did not matter. Through alienation, people and things become (...)

  13. Thought experiments, sentience, and animalism.Margarida Hermida - 2023 - Synthese 202 (5):148.
    Animalism is prima facie the most plausible view about what we are; it aligns better with science and common sense, and is metaphysically more parsimonious. Thought experiments involving the brain, however, tend to elicit intuitions contrary to animalism. In this paper, I examine two classical thought experiments from the literature, brain transplant and cerebrum transplant, and a new one, cerebrum regeneration. I argue that they are theoretically possible, but that a scientifically informed account of what would actually happen shows (...)

    Definition The authors’ definition of the autopoietic system has evolved through the years. One of them states that an autopoietic system is organized (defined as a unity) as a network of processes of production (transformation and destruction) of components that produces the components which: (1) through their interactions and transformations regenerate and realize the network of processes (relations) that produced them; and (2) constitute it (the machine) as a concrete unity in the space in which they exist by specifying the (...)

    Divergent Processing of Cell Stress Signals as the Basis of Cancer Progression: Licensing NFκB on Chromatin.Spiros A. Vlahopoulos - 2024 - IJMS 25 (16):8621.
    Inflammation is activated by diverse triggers that induce the expression of cytokines and adhesion molecules, which permit a succession of molecules and cells to deliver stimuli and functions that help the immune system clear the primary cause of tissue damage, whether this is an infection, a tumor, or a trauma. During inflammation, short-term changes in the expression and secretion of strong mediators of inflammation occur, while long-term changes occur to specific groups of cells. Long-term changes include cellular transdifferentiation for some (...)

  17. Emergentism and Sadra’s psychology; a common physicalistic challenge.Mahdi Homazadeh - 2019 - Asian Philosophy 29 (3):221-230.
    This paper first explores in detail a regenerated theory in philosophy of mind, known among contemporary philosophers as ‘emergentism’. By distinguishing strong and weak versions of the theory, I explain two important explanatory challenges presented by physicalists against this theory. In the following, I provide a brief overview of Sadr al-Muta’allihin’s theory of the incipience and degrees of the soul, examining similarities and differences between this theory and strong emergentism. Then, underlining the main aspects of similarity between the two theories, (...)

  18. The Hydra model - a model for what?Alfred Gierer - 2012 - International Journal of Developmental Biology 56:437-445.
    The introductory personal remarks refer to my motivations for choosing research projects, and for moving from physics to molecular biology and then to development, with Hydra as a model system. Historically, Trembley’s discovery of Hydra regeneration in 1744 was the begin¬ning of developmental biology as we understand it, with passionate debates about preformation versus de novo generation, mechanisms versus organisms. In fact, seemingly conflicting bottom-up and top-down concepts are both required in combination to understand development. In modern terms, this (...)

  19. Heraclitean Critique of Kantian and Enlightenment Ethics Through the Fijian ethos.Erman Kaplama - 2016 - Cosmos and History 12 (1):143-165.
    Kant makes a much-unexpected confession in a much-unexpected place. In the Criticism of the third paralogism of transcendental psychology of the first Critique Kant accepts the irrefutability of the Heraclitean notion of universal becoming or the transitory nature of all things, admitting the impossibility of positing a totally persistent and self-conscious subject. The major Heraclitean doctrine of panta rhei makes it impossible to conduct philosophical inquiry by assuming a self-conscious subject or “I,” which would potentially be in constant motion like (...)

    After a critique of the conservative and speculative approaches dominating the field of the protection and promotion of cultural heritage, the paper introduces a sociological perspective that considers cultural heritage an essential factor of identification and belonging, as well as a mean for the reproduction of life forms. The heritage of the past, in fact, is a living body contributing to the symbolic transmis-sion of the aesthetic, ethical and cognitive values of communities. Rather than the protection of guardians and the (...)

    Nearly 550 years ago, Guru Nanak put forward a new spiritual path. He called upon his followers to conform to a more practical way of life, reflecting a new social order. Guru Nanak wanted to empower the common man to seek and realize God, while living an honest family life, free from rituals, renunciations, and pilgrimages. His teachings were designed to promote equality among all humans. Nanakian Philosophy's governing belief in virtuous conduct is the guide to reach the ultimate reality. (...)

  23. Symposium on Another Mind-Body Problem.John Harfouch - 2020 - Syndicate.
    John Harfouch’s new book, Another Mind-Body Problem: A History of Racial Non-Being, argues that Immanuel Kant, widely considered the most influential philosopher of the modern period, is the first to claim the lives of non-white people are redundant and worthless. He articulates this through a metaphysics of minds and bodies that ultimately transforms the meaning of philosophy’s mind-body problem. A mind-body problem in the Kantian tradition is not a problem of how minds and bodies interact or brain states give rise (...)

  24. The Double-Movement Model of Forgiveness in Buddhist and Christian Rituals.Paul Reasoner & Charles Taliaferro - 2009 - European Journal for Philosophy of Religion 1 (1):27 - 39.
    We offer a model of moral reform and regeneration that involves a wrong-doer making two movements: on the one hand, he identifies with himself as the one who did the act, while he also intentionally moves away from that self (or set of desires and intentions) and moves toward a transformed identity. We see this model at work in the formal practice of contrition and reform in Christian and Buddhist rites. This paper is part of a broader project we (...)

  28. on creatively destructing.Konstantina Kalfa - 2014 - Rethinking Marxism 26 (4):581-591.
    Capitalism—as Marx has shown and Schumpeter has reminded us—has always promoted creative destruction practices. What in fact helps capitalism survive is the constant renewal of its products, modes of production, and needs through its own self-destructiveness. Capitalist destruction is a clearing out, a maneuver, a revaluation, and the presupposition for creation, all at once. It is a unification, the embracing of multiple and seemingly incompatible activities whose common component mainly consists in positivity: in their ability to reverse, to beautify destruction (...)

  33. Concepts and Dimensions of Conversion.Domenic Marbaniang - manuscript
    Since religious experiences are dependent on religious ‘truths’, and religious ‘truths’ are usually beyond scientific investigation, religious beliefs vary a lot and each claims credence of itself. Religious experiences leading to religious conversions or religious conversions due to conviction of certain religious beliefs are often observable. Whether a particular religious belief is true or false is dependent on the kind of criteria used for the measurement. Not all religions accept Logic as criteria, though.
