Autophagy functions in both selective and non‐selective ways to maintain cellular homeostasis. Endoplasmic reticulum autophagy (ER‐phagy) is a subclass of autophagy responsible for the degradation of the endoplasmic reticulum through selective encapsulation into autophagosomes. ER‐phagy occurs both under physiological conditions and in response to stress cues, and plays a crucial role in maintaining the homeostatic control of the organelle. Although specific receptors that target parts of the ER membrane, as well as, internal proteins for lysosomal degradation have been identified, the (...) molecular regulation of ER‐phagy has been elusive. Recent work has uncovered novel regulators of ER‐phagy that involve post‐translational modifications of ER‐resident proteins and functional cross‐talk with other cellular processes. Herein, we discuss how morphology affects the function of the peripheral ER, and how ER‐phagy modulates the turnover of this organelle. We also address how ER‐phagy is regulated at the molecular level, considering implications relevant to human diseases. (shrink)

Members of research ethics committees (RECs) face a number of ethical challenges when reviewing genomic research. These include issues regarding the content and type of consent, the return of individual research results, mechanisms of sharing specimens and health data, and appropriate community engagement efforts. This article presents the findings from a survey that sought to investigate the opinions and attitudes of REC members from four Arab countries in the Middle East and North Africa (Egypt, Morocco, Sudan, and Jordan) toward these (...) ethical issues. Our findings suggest that efforts are required to better familiarize REC members with the requirements for ethical biobank research. Additionally, we recommend that further research is undertaken with REC members regarding the main items that should be present in the Material Transfer Agreements /Data Transfer Agreements in their corresponding countries and the type of consent that should be used in genomic research.

BackgroundObstetrics and gynaecology always has reputation for being a highly litigious. The field of obstetrics and gynaecology is surrounded by different circumstances that stimulate the doctors to practice defensive medicine.MethodsThis study was directed to assess the extent and the possible effect of defensive medicine phenomenon on medical decision making among different grades of obstetric and gynaecologic Sudanese doctors, and to determine any experience of medical litigations with respect to sources and factors associated with it.ResultsA total of 117 doctors were approached, (...) their distribution according to job description was as follow: consultants registrars and specialists. The majority 89.7 % had the impression that litigation against doctors are increasing and 27.6 % had a direct experience of litigation. In this study less than one half of the surveyed doctors knew the concept of defensive medicine and 71.8 % reported practicing one or another form of defensive medicine. The different sources of the litigations reported by the doctors included: maternal death, perinatal death, other {misdiagnosis, intra-uterine fetal death, uterine perforation, rupture uterus}, fetal distress, injury to viscera and shoulder dystocia. In this study the experience of medical litigation was significantly observed among those who worked in area of blame culture. In logistic regression model, there was no significant difference between those who knew the concept of defence medicine and those who didn’t.ConclusionThere should be strategic plan to reduce the practice of defensive medicine and medical litigation against doctors.

This book intends to introduce readers to the work of Charles E. Butterworth, and thereby to introduce students to Medieval islamic political philosophy, of which Butterworth is one of the world's most prominent scholars. In a wider sense, the Festschrift introduces its readers to the current debates on Medieval islamic political philosophy, related as they are to the questions of the relationship between islam and Christianity, the Medieval to the Modern world, and reason and revelation. Butterworth's scholarship spans six decades, (...) primarily translating, editing, and interpreting the works of the Muslim political philosopher Alfarabi (d. 950) and Averroes (Ibn Rushd, d. 1198). He began his studies of Muslim political philosophy at a time when the Middle East and islam did not have the political salience they have acquired in more recent years. instead, Butterworth's reason for engaging with islam was rooted in the question of the relationship between reason and revelation. While one possible answer was pursued in the Christian, latin West, the islamic borderlands of Greek, Roman, and Muslim civilization offered another. By exploring Averroes, who provides the possibility of an Aristotelian-Islamic political philosophy, and Alfarabi, who pursues a Platonic-islamic political philosophy, Butterworth showed how islamic civilization provided a viable alternative to the theologico-political question reason v revelation, as well as serving as an inspiration to the latin West.

This paper examines the reasons for the high level of unmet needfor contraception in rural Egypt, using data from the individual survey andservice availability module of the 1988Ð89 Egypt Demographic and HealthSurvey. Two broad sets of potential factors are considered: characteristics ofa woman which influence her desire for children and thus her propensity touse contraception, and factors relating to the family planning serviceenvironment in which she lives. The results from a multivariate analysis showthat certain individual characteristics, such as family composition (...) andeducation, have a strong impact on the level of contraceptive use and on theproportion of total demand for spacing or limiting childbearing that is metby use of family planning. Unmet need, however, remains fairly constantacross demographic and socioeconomic subgroups of the population. Thelargest variations in unmet need are regional, but elements of the familyplanning services, namely the provision of a community-based nurse whodistributes family planning and female doctors at clinics, also play animportant role.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Population-based genomics studies have proven successful in identifying genetic variants associated with diseases. High-quality biospecimens linked with informative health data from diverse segments of the population have made such research possible. However, the success of biobank research depends on the willingness of the public to participate in this type of research. We aimed to explore the factors associated with the willingness of the public to participate in biobank research from four low- and middle-income countries in the Arab region (Egypt, Jordan, (...) Morocco, and Sudan). We used a previously validated questionnaire to assess several constructs that included the public’s perceptions, attitudes, and willingness to participate in biobank research. We recruited 967 participants. More than half did not have prior awareness of biobanks. Participants’ willingness to donate biospecimens and health data was less than 10%. Our results also showed that participants harbored concerns with trust, privacy, and with data-sharing involving international researchers. Predictors of willingness to participate in biobank research included no previous involvement in research and positive attitudes toward biobanks. Finally, our study showed several differences between the four countries regarding several of the investigated constructs. We conclude there should be additional efforts to raise public awareness and enhance perceptions of the public in biobanking research to enhance trust. We further recommend qualitative research to explore the underlying factors that contribute to the public’s concerns with international data sharing that would enhance global health. (shrink)

Ikhtisâr refers to the process of compilation a work by summarizing short and concise information or a large volume of work through abbreviation. It is intended to facilitate reading, learning and memorization, or to eliminate difficult parts in a book written in the form of Ikhtisâr. The compilation of concise works that fulfilled their purpose has become widespread over time and transformed into a tradition and also concise works have been compiled in fiqh as in other disciplines of sciences. In (...) particular, the work entitled Ghayâ fi’l-Ikhtisâr by Abu Shudjâ al-Isfahânî (d. after 500/1107), which is one of the concise works written in the Shafi'î madhhab, constitutes an important part of this tradition. In this study, primarily, the concise works written in the field of usûl/ancestor and furû/descendant in the Shafi’î madhhab were identified and given in chronological order, right after that, Ghayâ fi’l-Ikhtisâr and Ahmad bin Omar al-Shatirî’s (d. 1360/1941) work entitled Al-Yaqut al-Nafis were examined in terms of the ikhtisâr method. The comparative method was employed in order to determine the common and different aspects of these two works, which are among the basic sources of the Shafi'î madhhab, in terms of content and method. In this context, primarily, basic information regarding Ghayâ fi’l-Ikhtisâr and Al-Yaqut al-Nafis was presented, and right after that the classificcations and information in both works were compared and evaluated in terms of style. In this respect, it was determined that some of the topics in one of the aforementioned works are not included in the other work, and that there are certain differences between them in terms of the arrangement of the topics and the way they are explained. Based on this, in Ghayâ fi’l-Ikhtisâr the topics are dealt with in a brief manner and jurisprudential rulings are presented without giving much space to their evidences. In Al-Yaqut al-Nafis, on the other hand, each topic is dealt with in a detailed manner, and the elements, conditions and provisions related to the topics are mentioned as sub-headings. In particular, issues related to fiqh other than worship are explained with examples. Nevertheless, as in Ghayâ fi’l-Ikhtisâr the evidences of fiqh provisions are not included much. The topics in both works are arranged according to the Shafi'î fiqh methodology. (shrink)

Tahâvî (v. 321/ 933), hicrî üçüncü asrın sonları ile dördüncü asrın başlarında yaşamış Hanefî fakihidir. Tahâvî’nin daha çok muhaddis olarak tanınmasına rağmen hadis ve fıkha derin vukufiyeti, her iki alana da temas eden hadis-sahâbî kavlî münasebetini onun üzerinden incelemeyi daha anlamlı kılmaktadır. Müctehid fakihlerin hüküm istinbâtında başvurduğu sahâbî kavlî, Hz. Peygamber’e dayanması bakımından semâ/tevkif ihtimali bulunan bir delildir. Bu sebeple sahâbî kavlini sünnet birlikte değerlendirmenin lüzumu ortaya çıkmaktadır. Ayrıca Tahâvî’nin sahâbî kavli ile sünnet arasında net bir ayırım yapmaması, Hanefî usûlünün (...) teşekkül süreci açısından önemlidir. Tahâvî, ictihad usûlü anlayışında sahâbî kavline deliller hiyerarşisinde Kur’an, sünnet ve icmâdan sonra yer vermektedir. Eserlerindeki tercihleri dikkate alındığında Tahâvî, sahâbî kavlini tevkife hamlettiği yerlerde sünnet olarak değerlendirmektedir. Hatta sahâbî kavli ve uygulamasının icmâa dönüştüğü durumda sünneti neshedebilecek mertebede gördüğü anlaşılmaktadır. Tahâvî ictihadî olan, re’y ve te’vil ifade eden sahâbî kavlini ise mutlak delil almayıp bu durumdaki sahâbî kavli karşısında kıyasa gitmektedir. Tahâvî’nin sünnete ve sahâbî kavline bakışı birlikte değerlendirildiğinde dönemin hadis anlayışı gereği, sünnetin çerçevesini sahâbe ve tâbiûn kavillerini dahil ederek geniş kapsamda ele aldığı anlaşılmaktadır. Erken dönem Hanefî usûlünde sahâbî kavli hakkında Tahâvî’nin görüşlerinin incelendiği araştırmada metin incelemesi ve analizi yöntemi kullanılmış; Tahâvî’ye ait eserler ile erken dönem Hanefî usûl-i fıkıh eserleri mukâyeseli olarak ele alınmıştır.

When the first r lower extreme order statistics of a sample of large size n, 1 < r < s < n, are observed, asymptotic predictive intervals of the future extreme order statistic with a rank s are constructed. The only assumption that we adopt is that the first failure time is attracted to the Weibull distribution. In addition, we suggest an efficient point estimator of its shape parameter and then a confidence interval is constructed for it. Moreover, new interesting (...) asymptotic properties of the distributions that belong to the minimum domain of attraction of the Weibull distribution are revealed. Furthermore, extensive simulation studies are conducted to demonstrate the efficiency of the proposed methods. Two real datasets are analyzed to illustrate and corroborate the obtained results. The main results concern large samples. (shrink)

This paper presents the nonlinear dynamic analysis of energy-based models arisen from the applied systems characterized by the energy transport in the presence of fractional order derivative and time delay. The studied model is the fractional version of Bianca-Ferrara-Dalgaard-Strulik model of economy which is viewed as a transport network for energy in which the law of motion of capital occurs. By considering the time delay as bifurcation parameter, a proof to investigate the existence of Hopf bifurcation and the phase lock (...) solutions using the Poincare-Linstedt and the harmonic balance methods is given. At definite values of time delay, period-doubling bifurcations followed up by the consequences of chaotic states are detected. Simulation results assure that the BFDS model can generate new chaotic attractors beyond half order derivatives through the effect of the time delay on that system. In accordance with the literatures related to the problem of chaos, the concluded results confirm the proposed theorem by El-Borhamy in which the time delay possesses the ability to change the dynamic state of nonlinear systems from regular to chaotic within the fractional order derivative domain.

BackgroundOrgan donation has become one of the most effective ways to save lives and improve the quality of life for patients with end-stage organ failure. No previous studies have investigated the preferences for the different consenting options for organ donation in Egypt. This study aims to assess Egyptians’ preferences regarding consenting options for posthumous organ donation, and measure their awareness and acceptance of the Egyptian law articles regulating organ donation.MethodsA cross sectional study was conducted among 2743 participants over two years. (...) Each participant was required to rank eleven consenting options from 1 to 11, and to report his awareness and acceptance of the seven articles of the Egyptian law of organ donation.Results47% of the participants expressed willingness to donate their organs after death. This percentage increased to 78% when consenting options were explained to participants. “Informed consent by donor only” was the most preferred type of consent for one third of respondents. Awareness of the law articles regulating organ donation was relatively low ranging from 56% to 23%.ConclusionCurrently, around half of the Egyptian population agree to posthumous organ donation. This percentage could be increased significantly by raising the awareness about how the process of donation could be regulated and how the patient’s right of decision could be protected. (shrink)

Few figures of the Middle Ages command the attention of so many modern disciplines as Robert Grosseteste (c. 1170-1253). Theology, Philosophy, History, and Science are all areas which his life and thought continue to have significance and to inspire re-interpretation. Accompanied by a series of original commentaries, this new edition of Grosseteste's work, with English translation, draws together the perspectives of modern scientists and medieval specialists. Volume I of a six volume series, Knowing and Speaking presents two of the earliest (...) of Grosseteste's works, the treatises On the Liberal Arts and On the Generation of Sounds. These are accompanied by a significant Middle English treatise on the Seven Liberal Arts whose anonymous fifteenth-century author translated and excerpted passages from Grosseteste's treatises in a re-imagining of their structure and function.0Each work is treated separately within the volume, which is constructed in three parts. On the Liberal Arts sets Grosseteste's thoughts on the arts subjects and emphasises moral concerns about the purpose of learning. On the Generation of Sounds builds on the theories and statements of On the Liberal Arts in connection to the production of sound, elaborating the earlier position, relating the generation of sounds to human vocal and speech production.

Maximum likelihood estimation, maximum product spacing, and Bayesian estimation based on Markov chain Monte Carlo methods have been determined to find the best estimation method. The Monte Carlo simulation is used to compare the three methods of estimation based on the ATIIP-censored sample, and also, we made a bootstrap confidence interval estimation. We will analyze data related to the (...) distribution about single carbon fiber and electrical data as real data cases to show how the schemes work in practice. (shrink)

Currently there are persistent doubts about the meaning and contributions of the gene concept, mostly related to its interpretation as a stretch of DNA encoding a single functional product, i.e., the classical molecular gene concept. There is, however, much conceptual variation around genes, leading to important difficulties in genetics teaching. We investigated whether and how conceptual variation related to the gene concept and gene function models is present in school science and what potential problems it may bring to genetics teaching (...) and learning. Here, we report results on how ideas about genes and gene function are treated in textbooks and appear in students’ views and, also, about a teaching strategy for improving higher education students’ understanding of scientific models and conceptual variation around genes and their functions.

The purpose of this essay is to analyze succinctly the concept of faith through the very penetrating gaze of the Danish philosopher Sören Kierkegaard. Faith is analyzed by Kierkegaard from absurdity, resignation and the paradox of faith. In the same way, his concept of faith is carved with a chisel that would complete all his philosophy, that is, to touch human reality away from any abstract thought, trying at all times that his examination be seen on a personal dimension in (...) his rigorously individual coret.

BackgroundIn December 2014, China announced that only voluntarily donated organs from citizens would be used for transplantation after January 1, 2015. Many medical professionals worldwide believe that China has stopped using organs from death-row prisoners.DiscussionIn the present article, we briefly review the historical development of organ procurement from death-row prisoners in China and comprehensively analyze the social-political background and the legal basis of the announcement. The announcement was not accompanied by any change in organ sourcing legislations or regulations. As a (...) fact, the use of prisoner organs remains legal in China. Even after January 2015, key Chinese transplant officials have repeatedly stated that death-row prisoners have the same right as regular citizens to “voluntarily donate” organs. This perpetuates an unethical organ procurement system in ongoing violation of international standards.ConclusionsOrgan sourcing from death-row prisoners has not stopped in China. The 2014 announcement refers to the intention to stop the use of organs illegally harvested without the consent of the prisoners. Prisoner organs procured with “consent” are now simply labelled as “voluntarily donations from citizens”. The semantic switch may whitewash sourcing from both death-row prisoners and prisoners of conscience. China can gain credibility only by enacting new legislation prohibiting use of prisoner organs and by making its organ sourcing system open to international inspections. Until international ethical standards are transparently met, sanctions should remain. (shrink)
