To help to overcome this problem, we believe that we can shed some light to vitality estimation in hanging cases by making immunohistochemical staining of IL-1β antibody at the ligature mark of hanging. |
We used 20 male-female, 400-500 gr weighing, 10-12 months year old Wistar Albino kind of rats for this study. |
After applying general anesthesia to the rats in the antemortem hanging group, we took samples of antemortem control group from abdominal skin and we hanged rats with a mechanism. |
We waited for the formation of hanging ligature mark in the neck skin and we took hanging ligature mark skin samples 2 hours, 24 hours and 72 hours after hanging procedure. |
After applying sacrification to the rats in the postmortem hanging group, we took samples of postmortem control group from abdominal skin and hanged rats with the same mechanism. |
After waiting 2 hours for the formation of hanging ligature mark in the neck skin, we took postmortem ligature mark skin samples. |
In epidermal cells; antemortem hanging control group did not show IL-1β antibody staining, the diffuseness of IL-1β antibody staining in antemortem hanging 2th hour samples was strong, the diffuseness of staining was slightly decreased in 24th and 72th hour samples, and there was no IL-1β antibody staining in postmortem hanging control group and postmortem 2th hour group. In adnexal cells; antemortem and postmortem hanging control groups did not show IL-1β antibody staining, the diffuseness of IL-1β antibody staining in antemortem hanging 2th hour samples was moderately to strong, the diffuseness of staining was slightly decreased in 24th and 72th hour samples, and the half of samples in postmortem hanging 2th hour group did not show IL-1β antibody staining. |
In adnexal cells; antemortem and postmortem hanging control groups did not show IL-1β antibody staining, the diffuseness of IL-1β antibody staining in antemortem hanging 2th hour samples was moderately to strong, the diffuseness of staining was slightly decreased in 24th and 72th hour samples, and the half of samples in postmortem hanging 2th hour group did not show IL-1β antibody staining. In epidermal cells; antemortem hanging control group did not show IL-1β antibody staining, the diffuseness of IL-1β antibody staining in antemortem hanging 2th hour samples was strong, the diffuseness of staining was slightly decreased in 24th and 72th hour samples, and there was no IL-1β antibody staining in postmortem hanging control group and postmortem 2th hour group. |
In subepidermal cells; the most of antemortem and postmortem hanging control group samples showed slight IL-1β antibody staining diffuseness, the diffuseness of IL-1β antibody staining in antemortem and postmortem hanging 2th hour samples was increased compared to the both control groups, and there was slight staining diffuseness in antemortem hanging 24th and 72th hour samples. In adnexal cells; antemortem and postmortem hanging control groups did not show IL-1β antibody staining, the diffuseness of IL-1β antibody staining in antemortem hanging 2th hour samples was moderately to strong, the diffuseness of staining was slightly decreased in 24th and 72th hour samples, and the half of samples in postmortem hanging 2th hour group did not show IL-1β antibody staining. |
Of all groups, the majority of vascular structure cells did not show IL-1β antibody staining. |
As a result of all these findings, with IL-1β antibody immunostaining of hanging ligature mark skin, epidermal and adnexal cells can discriminate antemortem-postmortem hangings. |
We think that, IL-1β with immunohistochemical methods can be used for vitality estimation. |
STR loci are commonly used in nuclear DNA Identification and paternity testing in forensic science. |
The aim of this study is to generalize the X-SNPs loci location on X chromosome (X108, X029, X036, X046, X056, X059, X062, X076, X085, x109, X121, X122, X135, X143, X165) and use these loci in Turkish population's polymorphism in forensic science. |

Investigation of The Effect of Chlamydia Pneumoniae in Sudden Deaths with Atherosclerosis Introduction and objective: 15-30 percent of natural deaths is sudden and unexpected death that the most common cause is atherosclerotic cardiovascular disease in our country and the world. |
Atherosclerosis is a highly morbid and mortal disease which has discussions about how it can be kept under the control. |
Infection was included due to classical risk factors don't explain epidemiological changes. |
Chlamydia Pneumoniae is a risk factor of atherosclerosis and complications of it like heart disease, myocardial infarction and death. |
The study was performed to evaluate the relationship of Chlamydia Pneumoniae with atherosclerosis and its classical risk factors. |
Material and Method: 33 sudden death cases were randomly selected which sent to Ankara Gruop Headship of Forensic Medicine Institutions for autopsy. |
Manner and place of death, postmortem intervals, hypertension, diabetes, other chronic diseases, history of family, cigarette smoking were recorded. There was no significant difference between increased subcutaneous fat tissue thickness with manner of death, hypertension, diabetes, smoking, family history. |
Blood samples were cryopreserved after centrifugation until IgA and IgG antibodies of Chlamydia Pneumoniae investigated with MIF test method. |
Tissue samples taken from two vessels were put into saline solutioun to detection of Chlamydia Pneumoniae genome. |
Chlamydia pneumoniae genome extractions were performed and had been amplified with using polymerase chain reaction. |
The majority of cases died at home, also hospital, open space and prison. |
The mean age is 51,9032 and higher in females than in males. |
Adding in BMI all cases have one or more risk factors. |
There are intensive and advanced macroscobic atherosclerosis findings in cases. |
There was no significant difference between increased subcutaneous fat tissue thickness with manner of death, hypertension, diabetes, smoking, family history. Manner and place of death, postmortem intervals, hypertension, diabetes, other chronic diseases, history of family, cigarette smoking were recorded. |
The mean age of hypertensives and smokers were found higher. |
In cases, the average heart weight is higher than normal. |
Average heart weight of males is higher than females. |
Discussion: According to our cases, the most frequent cause of death is atherosclerotic cardiovascular disease. |
As expected, the most frequent myocardial pathology is ischemia induced fibrosis and hypertrophy, ischemia and acute MI findings and there is a significant relationship between myocardial pathology with mean age. |
The most frequent coronary pathology is atherom plaque which contract coronars 70 percent or more. |
Also thrombus was detected in two case and AS complications in coronary increase with increasing age. |
However, this situation is evidence that is not only acute infection. |
According to MIF test results, there is 30,3 percent seropositivity. |
Seropositivity increases with age. |
A significant relationship was detected between seropositivity with HT which is a complication of AS. |
In our cases, frequency of C. pneumoniae is higher than rates which was given for Turkey in other literatures. |
This situation shows that we need create solutions for this problem. |
Result: We think that C. pneumoniae is associated with sudden and unexpected death because of C. pneumoniae frequency is high. |
In our country, the limited postmortem studies on this subject should be increased, preventable cause of death should be revealed. |

Risk factors associated with juvenile crimes have been studied under these subcategories family factors, biological factors, environmental factors, and so on. |
Other studies have been conducted that look into the effects of mass media tools and violent and aggressive behavior in juveniles and also the effects of mass media on short and long term negative behavior of juveniles. |
This study has aimed to investigate the influence of mass media on tendencies of criminal behavior of juveniles, and the awareness of parents about this subject. |
Participants were given a survey, with demographic information form, that has been designed by the researcher specifically for this research. |
When looked into parents with awareness women scored higher than men, and parents with higher education and income tended to be more aware of the effects of mass media on juveniles behavior than parents with lower education and less income. |

In this study, we have approached the conclusion that subacute and subchronic testosterone and DHEA administration decreased the body weights and locomotor activity (p<0,05), and they increased muscle strength (p<0,05) in rats. |
According to our pathological assesment, mishappen cell nuclei, interstitial fibrosis, disorganized myocardial fibers and leukocytic infiltrates were observed in high dose testosterone (100mg/ 100gr) –treated rats especially on 14th day. In subchronic (90 days) testosterone and DHEA treatment groups, mild changes such as mishappen cell nuclei, interstitial fibrosis, disorganized myocardial fibers and leukocytic infiltrates were observed. |
In subchronic (90 days) testosterone and DHEA treatment groups, mild changes such as mishappen cell nuclei, interstitial fibrosis, disorganized myocardial fibers and leukocytic infiltrates were observed. According to our pathological assesment, mishappen cell nuclei, interstitial fibrosis, disorganized myocardial fibers and leukocytic infiltrates were observed in high dose testosterone (100mg/ 100gr) –treated rats especially on 14th day. |
According to our echocardiographic study at 14th and 90th days, testosterone, especially at high doses, induced increase in left ventricular posterior wall diameter and ejection fraction (p<0.05). |
In this study, oxidative stress marker MDA increased slighty but significantly in testosterone and DHEA groups.On the other hand, SOD and GSHPx levels were slighty but not significantly increased intestosterone and DHEA groups.

This study aims to evaluate the self-respect and desperation level in teenagers who have been exposed to domestic violence, prevent violence and provide scientific contribution to the guidance to the guidance studies. |
The Research Group of this study is formed by the forty-six people aging between 12-18 who have come to the interviews to the Bakırköy Famiy Court as a result of the ongoing divorce lawsuits and who have been exposed to or have witnessed domestic physical, sexual or emotional violence. |
( t =2.44, df : 93; p <.02) It has been realized that Family Ralations Scale of the Self-Respect Scale in the Research Group ( t :3.42, df: 93; p <.01) and scores of Psychological Health are significantly higher than the Control Group. |
( t =2.44, df : 93; p <.02) It has been realized that Family Ralations Scale of the Self-Respect Scale in the Research Group ( t :3.42, df: 93; p <.01) and scores of Psychological Health are significantly higher than the Control Group. |
At the end of our study, it has been identified that domestic violence has effects on self-respect and desperation level which are influential on the child's future planning, academic achievement and social life. |
Specifically, family relations and identification of the problems related to psychological health should be taken into consideration in planning strategies for preventing violence and guidance studies. |
The main aim of this study is to investigate free recall and recognition task performances of the eyewitnesses after the incident without any intervention. |
The study consists of a pilot study and two experiments. |
The study is performed with collaboration of 212 volunteered female participants with ages 17-25, from various faculties of Hacettepe University (76 for pilot study, 96 for Experiment 1 and 40 for Experiment 2). |
In Experiment 1, participants watched a theft video and then they were asked to perform a free recall task and to vote their confidence level for their answers on a Likert type scale. |
Then, a recognition task was performed in which true photographs (original still images from the video) that are prepared according to results from pilot study; manipulated photographs (manipulated versions of the still images from the video), and false photographs (still images that contain details that are not present in the video) are used. |
In Experiment 2, the same procedure is followed without free recall task. |
Results show that in recognition after free recall task, manipulated photographs cause the most memory error while the participants have the highest confidence levels for them. Comparison of the performances of free recall and recognition tasks showed that memory errors are observed most in manipulated photographs, among all image types in recognition task. |
An eyewitness has difficulty in recognizing small scale differences in details of the incident he or she eyewitnessed but is confident in his or her answer. |
Eyewitnesses made the most memory errors in their answers for manipulated photographs, and again with top confidence levels. |
Comparison of the performances of free recall and recognition tasks showed that memory errors are observed most in manipulated photographs, among all image types in recognition task. |
When asked to detect the details following the free recall, the rate of correct remembrance of the details is the same with free recall task. |
Study reveals that in order to obtain the most reliable information, free recall without any intervention whatsoever should be performed first. |

Every year 4-5 million people worldwide die from cardiac related causes. |
The most common genetic reasons of sudden cardiac death are structural defects suc as hypertrophic cardiomyopathy, aritmogenic right ventricular cardiomyopath, and the groups in which primary reason is arrhythmia, but no evidence in autopsy such as long QT syndrome, short QT syndrome, Katekolaminergic Polymorphic Ventricular Tashycardia, Brugada Syndrome. |
In our study, we gathered biological samples both from people between 5-40 years whose death reasons are sudden heart death and healthy athletes who are already medically inspected. |
In addition to all known genes and variations that are involved in cardiovascular diseases, we also used cardiovascular disease panel that has a DNA microchip with 196.725 SNP marker containing gene loci that are involved in sudden heart death. |
In our study that is aimed to emerge both genetic variation information and genetic variations that cause sudden cardiac disease, we determined rs2971851 and rs9609516 polymorphisms that are unique for Turkish Population. |
In this study, it is aimed that searching of relationship between characteristical features of fingerprint's among themselves and gender, that can improve the quality of low image-quality fingerprints, that can complete the fingerprint estimating invisible part of fingerprint from visible part of fingerprint and that can allow the determination of gender to develop a new fingerprint recognation algorithm using fingerprint. |
Within the scope of the study, totaly 130 fingerprints were obtained from volunteers including 65 male and 65 female individuals. |
Characteristical features of fingerprints were counted and classified, prepared data was tested with Pearson Correlation Analysis method. |
As a result, it is brought up that there is a relationship between characteristical features of a fingerprint with the same individual's other fingerprints and the individual's gender. |
The aim of the study is to evaluate the frequency of driver's involvement in fatal accidents according to his socio-demographical characteristic and to compare the driver's fault rate determination in fatal traffic accidents in a year with the other expert reports by examining the fatal traffic accidents forensic files sent to traffic expertise board of Ankara group chairmanship of the council of forensic medicine with formal request for fault situation determination.
