Several phenotypes can come from transcription regulation. Sequence-specific transcription factors are needed to effectively execute transcriptional programs, however they are often not operating alone. Polycomb PcG proteins are a well-known class of chromatin regulators found in Drosophila melanogaster and other species, including humans. As time passed, the concept of a PCG gene or protein shifted from the original phenotypic meaning of mutant flies to the contemporary biochemical description. PCG genes and proteins are under investigation for their critical contributions to physiology and their cancer treatment potential. Adding additional PcG members, with substantial responsibilities in PRC modulation, has opened new routes of inquiry in the issue. It is still needed to discover the many PRC variations' roles and how their catalytic activity is controlled. This review covers mutually exclusive PRC2 variants and employs a technique like the one used for PRC1 variants. Based on current biochemical findings, these classifications are valid. More auxiliary PcG subunit research is needed for now. Moreover, it is unknown how many PRC cell variations occur (hypothetically, there could be more than 100 different PRC variants).In order to fully elucidate the new PcG proteins and complexes, it is necessary to perform comprehensive research. We must study context-specific genetic modifications to better provide remedies. Current anti-cancer drugs target mainly the core subunits and catalytic activity of PRC2 and PRC1, and understanding these functions is critical. Targeting each particular activity that has been deregulated might be rather beneficial. PCG proteins are involved in oncogenesis, tumor suppression, and development/congenital illness as well. PcG involvement in cancer, once revealed, would be intriguing. Successful and effective therapeutic therapies will be helped by a detailed understanding of the pathways that contain PcG proteins.

Sexual Repression

This article examines how female conditioning and sexual repression affect the woman’s sense of self, womanhood, identity and her place in society. It argues that the woman’s body is at the core of the many sites of gender struggles/ politics. Accordingly, the woman’s body must be decolonised for her to attain true emancipation. On the one hand, this study identifies the grave consequences of sexual repression, how it robs women of their freedom to choose whom to love or marry, the freedom to seek legal redress against sexual abuse and terror, and how it hinders their quest for self-determination. On the other hand, it underscores the need to give women sexual freedom that must be respected and enforced by law for the overall good of society.

AbstractAs the “new rangeland paradigm” took shape in the 1990s, climatic variability in pastoral ecosystems was often discussed as “uncertainty”, and the essential mobility of pastoral systems was argued to be possible only with flexible land access rights. These context-specific principles have increasingly been globalized in analyses of diverse pastoral systems. While new understandings of the role of uncertainty and flexibility in pastoral systems have been unquestionably beneficial for particular contexts, uncertainty has been problematically embraced as intrinsically central to pastoral systems.This paper combines a critical review of the literature and field work in Tajikistan’s Rasht Valley to bring into clear relief differences between variability and uncertainty, on the one hand, and mobility and flexibility, on the other. This allows us to see that livestock mobility is a strategy to cope with environmental variability in all pastoral contexts. Flexibility, however, is a strategy to cope with environmental uncertainty that is only present in a subset of pastoral contexts. Importantly, flexibility is not a required precondition for mobility. These realizations carry important implications for governance in pastoral settings. Due to the many challenges of building flexibility into property systems, pastoral land governance should be developed by looking for predictability, and efforts to maintain flexibility should be judicious and empirically well-justified.

Two aspects of Schumpeter' legacy are analyzed in the article. On the one hand, he can be viewed as the custodian of the neoclassical harvest supplementing to its stock of inherited knowledge. On the other hand, the innovative character of his works is emphasized that allows to consider him a proponent of hetherodoxy. It is stressed that Schumpeter's revolutionary challenge can lead to radical changes in modern economics.

The Viennese modern choreographer Gertrud Bodenwieser's black coat leads to an analysis of her choreography in four main phases – the early European career; the rise of Nazism; war's brutality; and postwar attempts at reconciliation. Utilising archival and embodied research, the article focuses on a selection of Bodenwieser costumes that survived her journey from Vienna, or were remade in Australia, and their role in the dramaturgy of works such as Swinging Bells (1926), The Masks of Lucifer (1936, 1944), Cain and Abel (1940) and The One and the Many (1946). In addition to dance history, costume studies provides a distinctive way to engage with the question of what remains of performance, and what survives of the historical conditions and experience of modern dance-drama. Throughout, Hannah Arendt's book The Human Condition (1958) provides a critical guide to the acts of reconstruction undertaken by Bodenwieser as an émigré choreographer in the practice of her craft, and its ‘materializing reification’ of creative thought. As a study in affective memory, information regarding Bodenwieser's personal life becomes interwoven with the author's response to the material evidence of costumes, oral histories and documents located in various Australian archives. By resurrecting the ‘dead letters’ of this choreography, the article therefore considers how dance costumes offer the trace of an artistic resistance to totalitarianism.

To reason with existential rules (a.k.a. tuple-generating dependencies), one often computes universal models. Among the many such models of different structure and cardinality, the core is arguably the “best”. Especially for finitely satisfiable theories, where the core is the unique smallest universal model, it has advantages in query answering, non-monotonic reasoning, and data exchange. Unfortunately, computing cores is difficult and not supported by most reasoners. We therefore propose ways of computing cores using practically implemented methods from rule reasoning and answer set programming. Our focus is on cases where the standard chase algorithm produces a core. We characterise this desirable situation in general terms that apply to a large class of cores, derive concrete approaches for decidable special cases, and generalise these approaches to non-monotonic extensions of existential rules.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

: Heterocyclic compounds represent a significant target for anti-cancer research and drug discovery, due to their structural and chemical diversity. Oxazoles, with oxygen and nitrogen atoms present in the core structure, enable various types of interactions with different enzymes and receptors, favoring the discovery of new drugs. Aim of this review is to describe the most recent reports on the use of oxazole-based compounds in anticancer research, with reference to the newly discovered iso/oxazole-based drugs, to their synthesis and to the evaluation of the most biologically active derivatives. The corresponding dehydrogenated derivatives, i.e. iso/oxazolines and iso/oxazolidines, are also reported.

Emerson’s Memory Loss is about an archive of texts documenting Emerson’s intellectual state during the final phase of his life, as he underwent dementia. It is also about the way these texts provoke a rereading of the more familiar canon of Emerson’s thinking. Emerson’s memory loss, Hanlon argues, contributed to the shaping of a line of thought in America that emphasizes the social over the solipsistic, the affective over the distant, the many over the one. Emerson regarded his output during the time when his patterns of cognition transformed profoundly as a regathering of focus on the nature of memory and of thinking itself. His late texts theorize Emerson’s experience of senescence even as they disrupt his prior valorizations of the independent mind teeming with self-sufficient conviction. But still, these late writings have succumbed to a process of critical forgetting—either ignored by scholars or denied inclusion in Emerson’s oeuvre. Attending to a manuscript archive that reveals the extent to which Emerson collaborated with others—especially his daughter, Ellen Tucker Emerson—to articulate what he considered his most important work even as his ability to do so independently waned, Hanlon measures the resonance of these late texts across the stretch of Emerson’s thinking, including his writing about Margaret Fuller and his meditations on streams of thought that verge unto those of his godson, William James. Such ventures bring us toward a self defined less by its anxiety of overinfluence than by its communality, its very connectedness with myriad others.
