Cukurova Medical Journal , 2013,
Abstract: Purpose: Mental retardation is a common handicap (2-3% of the general population) with an unknown cause in more than 50% of mentally retarded patients. Important causes are chromosome abnormalities which are detectable in 4-28% of cases, depending on the patient selection and techniques used. Aim of the study was to determine possible association between atypic facial appearance, mental retardation and the translocation [t(16;19)(q24;q12)x2] between two copy of non homolog chromosomes. Materials and Methods: Chromosomal analysis of peripheral blood lymphocytes from the proband and her family were performed with standart protocols at the Cukurova University hospital in Turkey. Results: We assessed the second and third generation of the family in which the translocation between chromosomes 16 and 19 segregates: one of the three progenies with the karyotype 46,XY, t(16;19)(q24;q12) was heterozygote for the translocation and presented normal phenotype. One of the three progenies with the karyotype 46,XY presented normal phenotype also and the third with the karyotype 46,XY [t(16;19)(q24;q12)x2] was the proband. The parents were consanguinous, heterozygote for the translocation, and presented normal phenotype. Conclusions: Atypialc facial appearance and mental retardation could be associated with the homozygote translocation. These findings can be used in clinical genetics and may be used as an effective tool for reproductive guidance and genetic counseling. [Cukurova Med J 2013; 38(3.000): 540-542]
The influence of pericentric inversion in 10th chromosome on aggressive behavior and hyperactivity
Nilgun Tanriverdi,Ayfer Pazarbasi,Dilara Karahan,Ayse Avci
Cukurova Medical Journal , 2013,
Abstract: Aggressive behavior and hyperactivity are neurodevelopmental diseases with unknown pathogenesis. Pericentric inv(10)(p11.2;q21.2) mutation is frequently encountered in cytogenetic laboratories. This mutation is accepted as a polymorphic variant and is phenotypically silent, but in some cases it has been associated with neurodevelopmental diseases like autism. After blood culturing, standard chromosome obtaining procedure was applied to patients. In this study, clinical and cytogenetical findings of a boy with developmental delay, mental and motor retardation, attention deficit and hyperactivity have been reported. As a result of chromosome analysis, on chromosome 10, a large pericentric inversion between p11.1 and q22.q bands has been found. Karyotype analysis was also performed to mother, father and siblings of the patient and they have been found to have normal karyotype. It is plausible to consider a relation between inv(10) and some behavioral problems. Additionally, molecular studies targeting 10p-q critical region will be more informative for the true identification of this disease. [Cukurova Med J 2013; 38(1.000): 108-113]

Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.612089

In this study, the crust and upper mantle structure of Anatolia have been investigated by measuring the group velocity dispersion data of discriminated seismic surface waves. In the scope of the study, it has selected the profiles between six stations located in western Anatolia of Bogazici University Kandilli Observatory Earthquake Research Institute, national network of Turkey, and records of an earthquake (having about 10° epicentral distance) occurred in the eastern of Anatolia have been used. Firstly, surface wave discrimination filter based on the polarization properties has been applied tothree-component recordsand emphasized to surface waves. Then the group velocities have been calculated by multiple filter technique. A five-layered crustal model having total thickness of 38 - 40 km and Pn-wave velocity of 8.00 km/sec in the upper-mantle has been determined through inversion of surface wave group velocity dispersion data in the period range of 10 sec to 60 sec.

Fear of Crime among Women in the Old City Center of Istanbul  [PDF]
Funda Yirmibesoglu, Nilgun Ergun
Current Urban Studies (CUS) , 2015, DOI: 10.4236/cus.2015.32014
Abstract: Istanbul, the biggest city of Turkey with a population of 17 million people, is a city where both the negative and positive effects of urban life standards are intensely experienced. Along with problems such as migration from rural areas to urban areas, rapid population growth, unemployment and squatting, crime rates have recently been observed to go higher (Yirmibesoglu & Ergun, 2013). The old city center, Beyoglu was infamously known for its high crime rates and fear of crime, but today it seems that this image has changed and the fear of crime has decreased. Among the reasons for this decrease, we can mention the fact that Beyoglu has been through a gentrification process that some buildings have been restored, and that urban design implementations have been done in some streets. This study aimed to find out how fear of crime according to gender differed before and after the renovation process. With this aim in mind, field research and surveys were conducted in 2006 and 2010. The research problem, fear of crime and environmental safety in Beyoglu, was investigated based on certain variables such as the participants’ gender, occupation, duration of residence in Istanbul, the place of residence, age group, place of birth, and educational level; the participants were also asked about the frequency of their visits to Beyoglu and the reasons why they go to Beyoglu. The results of the study revealed the differences in fear of crime between men and women. It was found that Beyoglu district became safer after the renovations; yet, the rate of fear of walking alone, and therefore the fear of crime, was found to be higher among women than among men.

Physics , 2015, DOI: 10.1016/j.newast.2013.03.013
Abstract: This study aims to analyse the elemental abundances for the late B type supergiant star $\sigma$ Cyg and the early A-type supergiant $\eta$ Leo using ATLAS9 (Kurucz, 1995; Sbordone et al., 2004), assuming local thermodynamic equilibrium (LTE). The spectra used in this study are obtained from Dominion Astrophysical Observatory and have high resolution and signal-to-noise ratios. The effective temperature and the surface gravity of $\sigma$ Cyg are determined from the ionisation equilibria of Al I/II, Mg I/II, Fe I/II, Fe II/III , and by fitting to the wings of H$_\gamma$ and H$_\beta$ profiles as $\textit{T}$$_{eff}$ = 10388 K and log $\textit{g}$ = 1.80. The elemental abundances of $\eta$ Leo} are determined using $\textit{T}$$_{eff}$ = 9600 K and log $\textit{g}$ = 2.00, as reported by Przybilla et al. (2006). The ionisation equilibria of C I/II, N I/II, Mg I/II, Ca I/II, Cr I/II and Fe I/II/III are also satisfied in the atmosphere of $\eta$ Leo. The radial velocities of $\sigma$ Cyg and $\eta$ Leo are -7.25$\pm$7.57 km s$^{-1}$ and 10.40 $\pm$ 13.37 km s$^{-1}$, respectively. The derived projected rotational velocities \textit{vsini} from synthetic spectra are 27 and 2 km s$^{-1}$ for both stars, respectively. The macroturbulent velocities ($\zeta$) are 24 $\pm$ 2 km s$^{-1}$ and 14.5 $\pm$ 1.5 km s$^{-1}$. Also, the microturbulent velocities ($\xi$) have been determined for both of stars as 3.5 km s$^{-1}$. The CNO abundance results of $\sigma$ Cyg and $\eta$ Leo show C deficiency, N overabundance and O in excess.

Journal of Animal and Veterinary Advances , 2012,
Abstract: The effect of Caloric Restriction (CR) on life span of fresh water rotifer (Brachionus calyciflorus) was investigated in this study. Groups were fed at 12, 24, 36, 48, 60 and 72 h intervals with 0.5 mL (1.5x106 cell mL-1) Chlorella sp. to apply CR. Significant changes were observed in maximum and average life spans in groups subjected to CR (p<0.05). Maximum life span in 36 h group was determined as 15 days, while it was 10 days in control group. Reproduction life span was observed to be increasing in spite of decreasing number of eggs. The results show that CR affected life span and reproduction in rotifer B. calyciflorus.

A Web Based Puzzle for Energy Sources
The Turkish Online Journal of Distance Education , 2006,
Abstract: At present many countries in the world consume too much fossil fuels such as petroleum, natural gas and coal to meet their energy needs. These fossil fuels are not renewable; their sources are limited and reducing gradually. More importantly they have been becoming more expensive day by day and their damage to the environment has been increasing. In spite of it, renewable energy sources are renewed and never run out. In addition there are many benefits of renewable energy. In this study a puzzle is prepared for primary-school students aiming at teaching of energy sources as a supplementary source. In the mean time, the puzzle we prepared reveals the advantages and disadvantages of renewable and fossil energy sources. Here, the student’s aim is to complete the puzzle by answering the questions respectively. .
Effects of Divorce on Children

Psikiyatride Guncel Yaklasimlar , 2013,
Abstract: There is now strong consensus in the research literature that children whose parents have divorced are at increased risk of displaying a variety of problem behaviors compared to children living in continuously intact families. Divorce can be a profound catalyst for psychological, social, and economic change. Also, many studies have documented short-term and long-term negative effects of parental marital conflict and divorce for offspring, including poorer academic, social, and psychological outcomes. Researches indicate that adult offspring of divorce were experiencing more problems lifelong and evaluate divorce their own marriages than do young adults from intact families. It has been suggested that the long-term consequences of parental divorce for adult attachment and quality of life may prove to be more serious than the short-term emotional and social problems noted in childhood. As a result, divorce may lead to further stressful experiences such as disruption in parent-child relationships, loss of emotional support, economic hardship, and as well as numerous other stressful life events.
