8-hydroxydeoxyguanosine (8-OHdG) is the most frequent oxidative DNA damage. 8-oxo-deoxyguanosine DNA glycosylase 1 (OGG1) is involved in the repair of 8-OHdG. Many studies indicated that DNA repair is decreased in type 2 diabetes (T2DM). Single nucleotide polymorphisms in DNA repair genes may be linked to a decrease in DNA repair activity. The main objective of this study was to see how the OGG1 Ser326Cys gene polymorphism affected OGG1 expression and urinary excretion of 8-OHdG in T2DM patients. OGG1 expression and OGG1 genotyping in lymphocytes were detected by immunocytochemical staining and Polymerase Chain Reaction-Restriction Fragment Length Polymorphism assay, respectively. Urinary 8-OHdG levels were measured by using ELISA kit in patients with T2DM. Compared with control cases, patients with T2DM had lower OGG1 immunopositivity and higher urinary 8OHdG levels. No significant difference was found in OGG1 immunopositivity or urinary 8-OHdG levels between subjects with different OGG1 genotypes in both groups. In conclusion, The OGG1 Ser326Cys gene polymorphism has no effect on neither OGG1 expression nor urinary 8-OHdG levels. Increased urinary 8-OHdG levels despite low OGG1 immunopositivity may be derived from the action of other DNA repair enzymes.

Study of D+ → K-π+e+νe
(American Physical Society, 2016) Kolcu, Onur Buğra; The BESIII collaboration
We present an analysis of the decay D+ -> K-pi(+)e(+)nu(e) based on data collected by the BESIII experiment at the psi(3770) resonance. Using a nearly background-free sample of 18262 events, we measure the branching fraction B(D+ -> K-pi+e+nu e) = (3.77 +/- 0.03 +/- 0.08)%. For 0.8 < m(K pi) < 1.0 GeV/c(2), the partial branching fraction is B(D+ -> K-pi+e+nu e)([0.8,1.0]) = (3.39 +/- 0.03 +/- 0.08)%. A partial wave analysis shows that the dominant (K) over bar* (892)degrees component is accompanied by an S-wave contribution accounting for (6.05 +/- 0.22 +/- 0.18)% of the total rate and that other components are negligible. The parameters of the (K) over bar* (892)degrees resonance and of the form factors based on the spectroscopic pole dominance predictions are also measured. We also present a measurement of the (K) over bar* (892)degrees helicity basis form factors in a model-independent way.

Thirring Universe Model
(IOP Publishing Ltd, 2024) Yilmaz, Nazmi; Akilli, Mahmut; Akdeniz, K. G.
In recent years, there has been a significant amount of research focused on Thirring instantons. This study aims to employ the Thirring quantum model as a theoretical Universe model to gain a more profound understanding of the beginning of the Universe. For this, we propose to analyze the entropy of the quantum states of zero energy Thirring instanton solutions and the transition to other quantum states. Our findings by also using Lyapunov exponents and the cyclic attractors as comparative nonlinear methods show that there is no entropy corresponding to instanton solutions with zero energy and that the sudden increase in entropy indicates the formation of the Universe. We evaluate the implications of this study in terms of the standard Universe model. Thus we anticipate that these results have the potential to contribute significantly to our understanding of the origin of the Universe and highlight the role of chaos and complexity in its evolution.

Mobile Learning in Medicine
(SPIE-Int Soc Optical Engineering, 2013) Gulluoglu, Sabri Serkan
This paper outlines the main infrastructure for implicating mobile learning in medicine and present a sample mobile learning application for medical learning within the framework of mobile learning systems. Mobile technology is developing nowadays. In this case it will be useful to develop different learning environments using these innovations in internet based distance education. M-learning makes the most of being on location, providing immediate access, being connected, and acknowledges learning that occurs beyond formal learning settings, in places such as the workplace, home, and outdoors. Central to m-learning is the principle that it is the learner who is mobile rather than the device used to deliver m learning. The integration of mobile technologies into training has made learning more accessible and portable. Mobile technologies make it possible for a learner to have access to a computer and subsequently learning material and activities; at any time and in any place. Mobile devices can include: mobile phone, personal digital assistants (PDAs), personal digital media players (eg iPods, MP3 players), portable digital media players, portable digital multimedia players. Mobile learning (m-learning) is particularly important in medical education, and the major users of mobile devices are in the field of medicine. The contexts and environment in which learning occurs necessitates m-learning. Medical students are placed in hospital/clinical settings very early in training and require access to course information and to record and reflect on their experiences while on the move. As a result of this paper, this paper strives to compare and contrast mobile learning with normal learning in medicine from various perspectives and give insights and advises into the essential characteristics of both for sustaining medical education.
Twenty Years of World Kidney Day
(Nikan Research Inst, 2025) Ahim, Sina Salem; Hosseinian, Shiva; Bouya, Salehoddin; Habiby, Parham; Miri, Maryam; Homapour, Saba; Arismani, Rasoul Jafari
World Kidney Day (WKD), established in 2006, marks a pivotal milestone in 2026 as it celebrates its 20th anniversary. This event was first observed on March 9, 2006, as a joint initiative of the International Society of Nephrology (ISN) and the International Federation of Kidney Foundations (IFKF), now known as the International Kidney Foundation - World kidney alliance (IKF-WKA). The primary objective was to raise global awareness about the increasing burden of kidney diseases and to promote preventive behaviors and equitable access to care. Since its inception, WKD has grown into a powerful global movement, celebrated annually on the second Thursday of March by several countries across six continents. As WKD approaches its 20th anniversary in 2026, it offers a timely opportunity to reflect on two decades of achievements, challenges, and lessons learned. Over the past two decades, WKD has evolved from a modest awareness initiative into a globally recognized health campaign, uniting healthcare professionals, policymakers, and patient advocacy groups in the efforts against kidney disease. Finally, this event highlights the importance of addressing chronic kidney disease through awareness, prevention, screening, and comprehensive management to improve outcomes and reduce the global health burden of kidney disease.
Amen Parade and Used in Paintings
(Istanbul Univ, Research Inst Turkology, Dept Art History, 2014) Ustunipek, Mehmet; Ustunipek, Seyda
Primary schools (subyan mektebi) in Ottoman educational system were primarily established to teach Kuran-Kerim and had religious context. Besides children had to study alphabet (elifba) to read and write Kuran and in time some lessons were added to course programmes. Therefore, the context was enriched. Amen parade for children (Amin alayi) were mostly organised in response to beginning of primary school for the children of wealthy families. It was an important tradition in Ottoman social history. The rituals of this procession have been analysed by scholars in the context of education and social history. Besides the literature, there are also some paintings made by foreign and Turkish artists which are satisfactory documents for this subject. The subject matter of these paintings may be considered as genre paintings focusing on a special event. In the eighteenth century the paintings of Van Mour, some nighteenth century gravures and the paintings of Rifat Ceteci and Malik Aksel reflect this tradition from different points of view.

Amplitude Analysis of D+→KS0π+π+π-
(American Physical Society, 2019) Kolcu, Onur Buğra; The BESIII collaboration
The decay D+-> K-S(0)pi(+)pi(+)pi(-) is studied with an amplitude analysis using a data set of 2.93 fb(-1) of e(+)e(-) collisions at the psi(3770) peak accumulated by the BESIII detector. Intermediate states and nonresonant components, and their relative fractions and phases, have been determined. The significant amplitudes, which contribute to the model that best fits the data, are composed of five quasitwo-body decays K(S)(0)a(1)(1260)(+), (K) over bar (1)(1270)(0)pi(+) (K) over bar (1)(1400)(0)pi(+), (K) over bar (1)(1650)(0)pi(+), and (K) over bar (1460)(0)pi(+), a three-body decay K-S(0)pi(+)rho(0), as well as a nonresonant component K-S(0)pi(+)pi(+)pi(-). The dominant amplitude is K(S)(0)a(1)(1260)(+), with a fit fraction of (40.3 +/- 2.1 +/- 2.9)%, where the first and second uncertainties are statistical and systematic, respectively.
