Breast Milk Proteases
(Springer International Publishing, 2023) Şahin, O.N.; Briana, D.D.
The proteins contained in milk carry out a broad array of complicated biological functions. Some proteins in milk have one function in their intact form, whilst also containing a sequence of latent function that becomes active following splitting of the main peptide chain. This bioactivity may involve attacking harmful microbes in the gut as well as regulating the infant's immune response. Thus, they may confer an evolutionary advantage. Current evidence suggests that this unmasking of latent bioactivity actually begins even, whilst milk is still within the breast. A range of proteolytic enzymes (proteases) in milk act on proteins in the milk to produce these bioactive peptide sequences. Furthermore, these same enzymes retain their functionality in the infant's intestine, potentially performing a more important catalytic function than even the proteases secreted by the infant's developing gut. This may reflect the fact that newborn infants are somewhat inefficient in digesting milk unless assisted by the proteases present in milk. The bioactive sequences latent in certain milk protein precursors are released through a series of steps involving both milk-derived proteases and proteases secreted by the infant gut. One of the aims of research is to understand how this release of latent bioactivity orchestrated through protease activity contributes to an evolutionary advantage for the mother and child [1, 2]. © Springer Nature Switzerland AG 2023.

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.

Honor Killings in Turkey
(Common Ground Research Networks aaron.clark@commongroundpublishing.com, 2012) Cesur-Kiliçaslan, S.
The concept of honor is very important for an individual's integration into a group. A person's failure in this area causes her to feel ashamed and lose status. Honor permeates the common values and norms which determine relationships in a society. According to an ancient Turkish proverb, extramarital sexual intercourse is "like mud on a woman's face and like henna on a man's hand." The traditional punishment for women who have the "mud" on their faces referred to in this proverb, one which is not accepted to be marginal in the social perception, is generally death. Today, high number of murders committed due to this point of view in Turkey and the steps for preventing them are being discussed. Murderers who commit honor killings in Turkey generally emphasize the traditions of their tribes and do not use a religious discourse. The incidences in which men are killed are more unusual, and according to Islam, the man that takes part in fornication should be stoned to death along with the woman. However this rule was not practiced in either today's Turkey or even in the Ottoman Empire, which was ruled by sultans who claimed to be caliphs of all Muslims. This fact supports the idea that religion is not the main reason for honor killings. According to the former Turkish Penal Code (TPC), the punishment of a person could be reduced due to provocation if he murders someone for his honor because of the social pressure created by the concept of honor. Thus, his punishment could be smaller than the punishment of a person who committed a murder in another way. Today, there is no punishment reduction due to provocation, according to the new Turkish Penal Code which was put into force for conformity with the European Union. © Common Ground, Donald Morton, All Rights Reserved.

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.
Epigenetic Causes of Obesity
(Springer International Publishing, 2023) Şahin, O.N.; Özen, S.; Briana, D.D.
Obesity is a multifactorial disorder in which genetics, epigenetics and the environment all act and interact with each other. Through a number of investigative techniques, including linkage analysis, genome-wide association studies and large-scale sequencing of either the entire genome or the exon-containing component, a large number of genes have been implicated in the processes predisposing to severe obesity [1, 2]. At present, the number of locations on the genome with established associations with obesity exceeds 200 [3, 4]. Nonetheless, genetic variability is insufficient to account for the patterns of inheritance observed in obese individuals, and clustering in families also indicates epigenetic factors. Epigenetic modifications are also caused by changes in the environment, such as overfeeding [5, 6], and a proportion of epigenetic alterations appear irreversible. © Springer Nature Switzerland AG 2023.

Utility: Theories and Models
(Springer, 2021) Akkaya, M.
The aim of this study is to look at utility theory from a broad perspective. The main hypothesis in the theory of decision is that the person who is in the position of deciding is entitled to the “economic man.” Also, the individual acts rationally. Thus, utility is the ability to satisfy (eliminate) human needs of goods and services. Utility is basically a psychological concept and also is the basis of economics and finance. Three types of utility take place in the economics and finance literature: marginal utility, total utility, and average utility. In addition, two main approaches fall within utility comparison: cardinal utility theory and ordinal utility theory. Furthermore, expected utility theory forms the basis of traditional finance. Expected benefit theory assumes that people choose risky or uncertain opportunities by comparing the expected benefits from them. Allais and Ellsberg paradoxes criticize expected utility theory. Tversky and Kahneman (Econometrica, 47: 263–291, 1979) present that the expected utility axioms are violated for more reasonable lottery alternatives than in the Allais paradox and put a link between finance and psychology. The prospect theory of Tversky and Kahneman forms the basis of behavioral finance. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
Breast Milk Oligosaccharides
(Springer International Publishing, 2023) Şahin, O.N.; Özpinar, A.; Briana, D.D.
Oligosaccharides are polymeric molecules typically consisting of between three and around ten monosaccharide subunits. Human breast milk differs from that found in the majority of mammalian species by virtue of the rich mixture of oligosaccharides (at least 150 different types) that it contains at high levels. Human milk oligosaccharides (HMOs) in mature human milk are even more abundant than milk proteins. They are usually present at a concentration of 5-15 g/L, which means that, if the water content is disregarded, they are exceeded in amount only by disaccharide lactose and milk fats [1, 2]. © Springer Nature Switzerland AG 2023.

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.
Breast Milk and Leptin Resistance
(Springer International Publishing, 2023) Şahin, O.N.; Serdar, M.A.
Leptin, an endocrine signalling molecule released by fat tissue in proportion to the body fat mass, was discovered in 1994. It is a protein with a molecular mass of 160 kDa. The investigative focus following discovery was principally on the effects of the hormone on energy balance through its actions on the brain. The fact that leptin plays a key part in controlling energy balance came from observing patients lacking leptin. These individuals eat excessively and become obese as children. However, if leptin is replaced by artificial means, their appetite diminishes and they expend larger amounts of energy. This discovery led to the decision to try treating obese adults in general by leptin replacement or supplementation. This strategy is flawed, however, since the majority of obese individuals do not have any abnormality in the leptin alleles. Surprisingly, obese individuals actually have higher plasma concentrations of leptin than non-obese controls, yet they become obese. Thus, it appears they develop an insensitivity to leptin, meaning they are predisposed to weight gain and are unable to lose this extra weight. How leptin insensitivity occurs has not yet been fully elucidated, although several theories have been put forward, in particular the involvement of increased C-reactive protein, reduced transduction of signals triggered by leptin or lowered levels of activity by histone deacetylases [1-5]. At present the picture is incomplete, but it appears that the transportation of leptin across the blood-brain barrier is compromised in some way, and this is a key factor in pathogenesis [6-8]. © Springer Nature Switzerland AG 2023.

Morphometry of the Corpus Callosum
(Springer International Publishing, 2023) Acer, N.; Gurlek Celik, N.G.
The corpus callosum (CC) is the major pathway connecting the two cerebral hemispheres of the brain. It consists of four parts, the rostrum, genu, body, and splenium. The CC plays a central role in sensory, motor, and cognitive information in cerebral information transferring and integration between the two cerebral hemispheres. The CC has been studied in regard to morphological features with dimensions, age, and sex differences both in health and neuropsychiatric disorders. Quantitative analysis of the CC morphometry is best studied with T1 sequence on midsagittal MRI. It is known that there are sex and age differences in the size of the CC. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023. All rights reserved.
Programming Molecules in Early Life
(Springer International Publishing, 2023) Şahin, O.N.; Briana, D.D.
Children whose mothers suffered from obesity, diabetes mellitus, or who had feeding difficulties face an increased risk of metabolic disorders, research has shown [1, 2]. Furthermore, being bottle fed or starting supplementary formula milk at an early stage may result in obesity as a child and adult [3, 4]. This research also indicates that the mother's diet plays a role in how metabolism is programmed in her offspring. Children who consume a diet with excessive amounts of lipids and proteins from an early age may lay down more fat and have an increased body mass index (BMI). A diet very rich in protein may result in raised insulin levels, which can cause insulin insensitivity. Since blood glucose also increases as a consequence of raised insulin, lipogenesis is stimulated. Infant birth weight and a maternal diet with high macronutrient levels were found to be significantly correlated [5-8]. © Springer Nature Switzerland AG 2023. All rights reserved.

Hearing Loss in Neonates and Infants
(Springer International Publishing, 2023) Sizer, B.; Bayar Muluk, N.B.; Ankle, N.R.
A high societal and economic cost is incurred due to infant and child hearing loss due to the subsequent delay in speech and language development. By early diagnosis and therapy, children with hearing loss may improve their language and communication skills to the point that they can fully participate in and contribute to a hearing society [1, 2]. The public is becoming more aware of hearing loss, which has spurred the development of medical infrastructure and associated medical advancements to assist those with hearing loss. The diagnosis and treatment of hearing loss in newborns and babies have undergone a sea change with the implementation of a screening approach for congenital hearing loss [3, 4]. © Springer Nature Switzerland AG 2023.

Vector Autoregressive Model and Analysis
(Springer, 2021) Akkaya, M.
The aim of this study is to explain vector autoregressive (VAR) models and Granger causality. VAR is an econometric model that generalizes univariate autoregressive (AR) models. VAR is a regression model that can be considered as a kind of hybrid among univariate time series models. VAR models are generally defined as alternatives to structural models of large-scale simultaneous equations. All variables in the model are treated symmetrically with an equation for each variable explaining the development of the variable, depending on the lags of the variable in the model and the lags of all other variables. The method is simple. It is not necessary to specify which variables are endogenous or exogenous. VAR models are generally better than traditional structural models. Granger causality test developed by Granger is a test used to determine the direction of causality of the relationship in the presence of delayed relationship between two variables. Granger causality is really just a correlation between the present value of one variable and the past values of others; the movements of one variable do not mean that it causes the movements of another. For the VAR model and Granger causality, the variables that affect the consumer confidence index is analyzed by using Eviews. © The Authors 2021. All rights reserved.
