ABSTRCTIn recent times, Information and Communication Technology (ICT) hasbeen developed and widely spread around world. ICT is used in various sectorsand considered a basis in the emergence of some important technologies such asvirtual reality technology. Virtual Reality (VR) is a special technology as anadvanced technology connected to several fields, e.g. training, learning, science,engineering, medicine, military, etc. VR has great potentials which enabled toperform several phenomena and experiments. Hence, several scenarios havebecome available. The purpose of this study is to shed light (...) on virtual realitytechnology and list a glimpse of common publications and studies involved. (shrink)

DNA double‐strand breaks (DSBs) are extremely hazardous lesions for all DNA‐bearing organisms and the mechanisms of DSB repair are highly conserved. In the eukaryotic mitotic cell cycle, DSBs are often present following DNA replication while, in meiosis, hundreds of DSBs are generated as a prelude to the reshuffling of the maternally and paternally derived genomes. In both cases, the DSBs are repaired by a process called homologous recombinational repair (HRR), which utilises an intact DNA molecule as the repair template. Mitotic (...) and meiotic HRR are managed by ‘checkpoints’ that inhibit cell division until DSB repair is complete. Here we attempt to summarise the substantial recent progress in understanding the checkpoint management of HRR in mitosis (focussing mainly on mammals) and then go on to use this information as a framework for understanding the presumed checkpoint management of HRR in mammalian meiosis.

Johanna Knapstein,1 Daniel Grimm,1 Marcus A Wörns,1 Peter R Galle,1 Hauke Lang,2 Tim Zimmermann111st Department of Internal Medicine, Johannes Gutenberg-University, Mainz, Germany; 2Department of General, Visceral and Transplantation Surgery, Johannes Gutenberg-University, Mainz, GermanyIntroduction: Hepatitis C virus reinfection occurs universally after liver transplantation, with accelerated cirrhosis rates of up to 30% within 5 years after liver transplantation. Dual antiviral therapy with pegylated interferon-2a and ribavirin only reaches sustained virological response rates of ~30% after liver transplantation. With the approval of viral NS3/4A (...) protease inhibitors telaprevir, boceprevir, and simeprevir and the NS5B polymerase inhibitor sofosbuvir, combination therapy offers new therapeutic options for HCV-infected patients, resulting in considerably higher sustained virological response rates in the nontransplant setting. Case presentation: We report three cases of TVR-based triple antiviral therapy in HCV genotype 1 reinfected patients after liver transplantation, of whom a 57-year-old Caucasian female and a 43-year-old Caucasian male were therapy naïve, and a 49-year-old Caucasian male patient was pretreated ineffectively. After 4 weeks of therapy, viral load decreased one to three log10 and became negative in weeks 6 to 8 in the therapy naïve patients. The pretreated patient showed a negative viral load in week 4. TVR was administered over 12 weeks, 750 mg thrice daily. Doses of immunosuppression with cyclosporine were reduced four to six fold. Initial peg-IFN and RBV doses ranged from 135–180 µg/week and 800–1,200 mg/day, according to the patient's body weight. Doses of peg-IFN and RBV were adapted to 90–135 µg/week and 400–800 mg/day after 2 to 12 weeks of protease inhibitor therapy. Dual therapy was continued for 36 weeks with total treatment duration of 48 weeks in the therapy naïve patients leading to a sustained virological response 12 weeks after the end of therapy. In the pretreated patient a breakthrough was detected in week 24 and therapy was discontinued. Overall, antiviral therapy was well tolerated. Side effects included dysgeusia and anemia leading to erythropoietin application and blood transfusions. Conclusion: This case series emphasizes that triple therapy with TVR is an efficient treatment for therapy naïve HCV genotype 1 reinfected patients after liver transplantation. But therapeutic options for pretreated patients require improvement. Keyword: cyclosporine, interferon, ribavirin, hepatitis C, protease inhibitor. (shrink)

Drawing its strength from the UN Charter and UDHR, human rights ethics is a beacon of hope and a promise that requires continuous reaffirmation during these turbulent times. These two documents, with their unwavering faith in ‘fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations large and small,’ have shaped our understanding of human rights as global and universal ethics. However, this faith is now being severely (...) tested by four countercurrents: extremism, exclusionism, selectivism, and populism. These countercurrents pose significant and urgent human rights threats that activists, academics, and policymakers must confront by reasserting the basic core values of the UN Charter and UDHR.

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

It is the intention in this article to explain the electoral stagnation of the Republican People’s Party (Cumhuriyet Halk Partisi, CHP) in the light of the 2015 parliamentary elections in Turkey. Drawing on theories of voting behavior, the article uncovers the organizational shortcomings within the party and the problem of credibility that have emerged as significant impediments to the party in addressing long-term historical-structural issues, mainly the division of Turkish society between the religious periphery and the secular center. Furthermore, the (...) strong identification between the ruling Justice and Development Party (Adalet ve Kalkınma Partisi, AKP) and its partisans have made party-switching difficult, having been achieved, above all, through the provision of economic benefits and public services and the consolidation of party identification through growing polarization and division in Turkish politics. Last but not least, the changes to the political environment between the June 7 and November 1, 2015 elections, pushed stability and security to the top of the agenda, as well as AKP’s electoral adjustments in the run-up to the November 1 elections inhibited any possible flow of votes to the CHP.

A hub and spoke model offers an effective and efficient approach to providing informed guidance to those who need it. The National Center for Ethics in Health Care (NCEHC) at the Veterans Health Administration, Department of Veterans Affairs, is the largest known hub and spoke healthcare ethics delivery model. In this article, we describe ways NCEHC’s hub and spoke configuration succeeded during the COVID- 19 pandemic, as well as limitations of the model and possible improvements to inform adoption at other (...) healthcare systems.

The definitive book on ethics for chemical dependency treatment professionals.

The vast majority of contributions to the literature on spirituality in nursing make extravagant claims about transcendence, eternity, the numinous, higher powers, higher levels of existence, invisible forces, cosmic unity, the essence of humanity, or other supernatural concepts. Typically, these assertions are made without the support of argument or evidence; and, as a consequence, alternative ways of theorizing ‘spirituality’ have been closed off, while the lack of consistent scholarship has turned the topic into a metaphysical backwater. In this paper, I (...) adopt a different premise, rejecting unsupported claims, and surveying the ‘spirituality’ terrain from a naturalistic and reductionist perspective. I argue that, if we rid ourselves of non‐naturalistic assumptions, we will discover theoretical and clinical resources in health psychology, social psychology, neuropsychology, and pharmacopsychology – resources which confirm that it is possible to conceptualize the study of existential concerns, and how health professionals might respond to them, in a properly scientific manner. In order to illustrate the potential usefulness of these resources, I will take palliative care as an example. (shrink)

This text explores how human beings construe experience: experience as a resource, as a potential for understanding, representing and acting on reality.

Quantum mechanical measurements on a physical system are represented by observables - Hermitian operators on the state space of the observed system. It is an important question whether all observables may be realized, in principle, as measurements on a physical system. Dirac’s influential text ( [1], page 37) makes the following assertion on the question: The question now presents itself – Can every observable be measured? The answer theoretically is yes. In practice it may be very awkward, or perhaps even (...) beyond the ingenuity of the experimenter, to devise an apparatus which could measure some particular observable, but the theory always allows one to imagine that the measurement can be made. This Letter re-examines the question of whether it is possible, even in principle, to measure every quantum mechanical observable. Unexpectedly, ideas from com-. (shrink)

Cognitive Stylistics or Poetics has emerged as a powerful framework for the analysis of literary works due to the fact that it provides us with tools stemming from bodily experience which aim at universality. This proposal attempts to shed additional light on the analysis of the characters and settings carried out by Freeman (1995) by making use of some recent developments within the framework of Cognitive Linguistics, especially in connection with metonymy and image-schemas. It lends further support to the thesis (...) that Cognitive Poetics is endowed with explanatory power since it accounts both for the processes of generation and understanding of literary texts.

This paper investigates four questions related to ethical issues associated with the involvement of engineers and scientists in 'military work', including the influence of ethical values and beliefs, the role of gendered perspectives and moves beyond the purely technical. It fits strongly into a human (and planet)-centred systems perspective and extends my previous AI and Society papers on othering and narrative ethics, and ethics and social responsibility. It has two main contributions. The first involves an analysis of the literature through (...) the application of different ethical theories and the application of gendered analysis to discussion of masculinities in engineering and the military. The second is a survey of scientists and engineers to investigate their opinions and experiences. The conclusions draw together the results of these two contributions to provide preliminary responses to the four questions and include a series of recommendations covering education and training, ethical approval of work not involving human participants or animals, the need for organisational support, approaches covering wider perspectives and the encouragement of individual ethical commitment.

The notion of consent which rose to the forefront in biomedical ethics as an attempt to safeguard patients' autonomy, is relatively new. The notion itself requires qualification, for it precludes neither duress nor ignorance. More seriously, I argue here that consent is redundant except in situations where paternalism prevails. Paradoxically, these are the very situations where it may be difficult to uphold or to verify voluntary consent. I suggest that a request-based relationship has the potential to overcome these difficulties. It (...) enhances patients' participation in decision making, requires that the patients remain in command and avoids their subordination. Request is also more conducive to treatments that are representative of patients' own values and perceptions. In practice, what one wants and what one agrees to, often concur. But these are not conceptually identical issues, and they carry important differences of emphasis. (shrink)
