Background: Lead Zirconate Titanate (PZT) films were synthesized by sol gel technique. The growth of films on ITO, Si\SiO2\Ti\Au, Si\Au and Si\SiO2\Ti\Al substrates discussed. In this study, Zirconium nitrate, lead acetate, and Ti (IV) isoproxide used as raw materials. Besides, acetic acid used as a solvent and 2-methoxy ethanol used as a stabilizer for Ti structure. Along with this, PZT films have perovskite structure, thin-film perovskite structure with high dielectric properties and hysteresis loop have been investigated. Methods: The effects of the type’s substrate on dielectric properties the ferroelectric properties were investigated and compared PZT film which deposited in different substrates. The films annealed at 600°C to complete crystalline films. XRD shows tetragonal PZT films have a strong perovskite structure with [100] prefer plane orientation. SEM and cross-section technique used to study for PZT surface films. Results: The dielectric constant at room temperature was different values depending on the types of substrate. The dielectric properties of the PZT films measured at 1 kHz were 120-400 dielectric constant and dielectric loss 0.02-0.08 at room temperature and 1 kHz. Conclusion: The largest remnant polarization (Pr) and coercive field (Ec) are obtained for PZT film deposited on Si\SiO2\Ti\Au substrate, equal to 26.6 mC/cm2 and 38.3 kV/cm, as compared to 16.3 mC/cm2 and 32.2 kV/cm2 for PZT film deposited on ITO substrate.

Toxoplasma gondii is a common protozoan parasite, which infects warm-blooded mammals, including mice and humans, throughout the world. The negative effects of T. gondii infection on the human reproductive system have been documented, especially in females. However, only few studies have examined the effects of T. gondii infection on the male reproductive system. Previous research shows that T. gondii can induce DNA methylation in some gene promoters, which are key regulators of spermatogenesis. Therefore, this study aimed to evaluate the effects of curcumin on the activity of DNA methyltransferases (DNMTs), as well as selected genes, involved in spermatogenesis in spermatogenic cells. In the spermatogenic cells exposed to T. gondii, there was a significant increase in DNMT1 and DNMT3A gene expression and a significant reduction in HSPA1A, MTHR, and DAZL gene expression, compared to the controls. The present results showed that curcumin could regulate changes in T. gondii-mediated gene expression. The effect of T. gondii on DNMT activity was also investigated in this study. A 40 % increase in DNMT activity was observed due to T. gondii infection. However, DNMT activity was restored by treatment with 20 μM curcumin for eight hours. The results revealed that T. gondii increases the NF-κB activity, compared to the control group. The increase in NF-κB activity, induced by T. gondii, was inhibited by curcumin. In conclusion, T. gondii, by increasing DNMT expression and activity, leads to an increase in NF-κB activity in cells. On the other hand, curcumin reduced DNA methylation, induced by T. gondii, owing to its NF-κB-inhibiting properties. Therefore, curcumin, as a hypomethylating agent, can be potentially used to alleviate the negative effects of T. gondii on the male reproductive system., EXCLI Journal;Vol. 19. 2020, pp.

This study explores the role of education as means of creation and maintenance of religious hegemony in Iran and Turkey. In the context of this study, state-sponsored systems of mass education aim to socialize generations of children into accepting the ideology and values of the dominant groups as the normal state of affairs. Hegemony, thus, is advanced not solely by excluding oppositional forces but by moral leadership throughout the total ideological and socio-political structure. Reviewing the notion of education in Islam and the role of the Quran and Sunna and other sources of knowledge in Islam, the study focuses on the impact of Shari'a in forming the theories of state and education in Islam. Representing two different schools of Muslim thought, Iran and Turkey have different interpretations of the state and its role in education which determines the degree of involvement and extent of authority of the political and religious leaders over education. Unity of Islam and the state in the Iranian theocratic system provides an ideologically-laden education which is rooted in one principle: training a new generation of pious, “ideologically committed Muslims”. However, the endeavors of the Turkish secular state have been focused on establishing a mass popularized secular education in order to produce nationalist citizens. The Iranian revolution of 1979 contributed extensively to the awakening of the religious revival, calling for a shift from a Western model of social order to the one deeply rooted in Islamic beliefs and values. The close link between education and ideology in Iran is apparent from the goals set for educating the young, most of them openly political: acceptance of God's absolute authority manifested through the authority of ulama; support for the political, economic, and cultural unity of all Islamic global community (umma) and for oppressed peoples (mustaz’afin); rejection of every form of oppression, suffering, and domination. The four ideological pillars of the Islamic Republic, inseparability of religion and politics, Islamic revival, cultural revolution, and creation of a committed Muslim, have had a direct impact on Iranian education. The “Unity of Education Act” in the Republic of Turkey placed all educational activities under strict government control by introducing a state monopoly on education. Kemalism is based on an emphasis on national and republican principles and secularism in which religion has no place and is left out of the scope of formal education. Hence, the transmission of religious knowledge from one generation to another was only possible through informal channels such as family, the small community or underground activities of religious orders. Islam, however, gradually penetrated the public life in Turkey and challenged the secularism. The goal of the Turkish national education as to unite the entire nation through a national consciousness, to think along scientific lines, and intellectually as well as worldly, leaves no place for Islamic religious education. In spite of the government's emphasis on a secular and nationalist system, Islam remains as a force, particularly in its capacity to utilize new elements required for a modern society. Although Islam has not yet challenged the supremacy of secular education in Turkey, it expanded its influence both in formal and informal education, content and structure.

Background: Patients with transfusional iron overload have depended on iron chelation therapy and improving chelation regimens have been of the highest priority. The aim of this study was to compare effect of combined versus monotherapy with Deferoxamine (DFO) and Deferiprone (DFP) in iron overloaded beta thalassemia (BT) major patients Materials and Methods We studied 36 BT major patients (mean age 7.6±4.6; range 3–16 years) attending the Ormieh Motahari hospital for regular transfusional support. Patients were randomly allocated to receive one of the following two treatments: DFO in combination with DFP (n=12), DFO alone (n=12) and DFP alone (n=12). Serum ferritin level, liver enzymes, blood urea nitrogen, and creatinine and side effects were monitored over a 12 months period. Results: After one year, serum ferritin decreased more significantly in patients on DFO+DFP therapy compared to patients who only received DFO or DFP alone (P
