The synthesis of new magnesium porphyrazines, peripherally substituted with 14-membered dioxa-dithia (O2S2) and tetrathia (S 4) macrocycles has been accomplished by cyclotetramerization of (6Z)-1,3,4,9,10,12-hexahydro-2,5,8,11-benzodioxadithia-cyclotetradecine-6, 7-dicarbonitrile (3) or (6Z)-1,3,4,9,10,12-hexahydro-2,5,8,11- benzotetrathiacyclotetradecine-6,7-dicarbonitrile (5) in the presence of magnesium butanolate. The precursors were prepared from disodium salt of dithiomaleonitrile and o-xylenebis(1-chloro-3-oxapentane) (2) or o-xylenebis(1-chloro-3-thiapentane) (4). The metal-free porphyrazines are obtained by the treatment of these magnesium porphyrazines with trifluoroacetic acid. These new compounds are characterized by a combination of elemental analysis and 1H, 13C NMR, IR, UV-vis and MS spectral data. Copyright © 2011 Published by Elsevier B.V. All rights reserved.

Radiographic evaluation of mineralization and eruption stages of third molars using dental panoramic radiographies can be an efficient tool for chronological age estimation in both forensic sciences and legal medicine. The third molar tooth is utilized for dental age estimation about the age span of 15-23 years because it represents the only tooth still in development. The aim of this study is to obtain and analyze data regarding third molar development and eruption in Turkish population for dental age estimation. A total of 744 dental panoramic radiographies of 394 female and 350 male subjects aged between 8 and 22 years were examined. Third molar development was determined according to the Nolla classification system, and eruption was assessed relative to the alveolar bone level. Mandibular and maxillary third molars were generally found at similar stages of development on both sides. Nolla stage 6 (completed crown calcification) was reached at around the age of 15 in both maxillary and mandibular third molars in both sexes. Alveolar emergence was at around the age of 16 in males and around age of 17 in females. Although third molars' eruption shows greater variability than development of third molars, data which were obtained from this study about eruption of these teeth can be supportive to development data for age estimation. © Springer-Verlag Berlin Heidelberg 2012.

Introduction: Sex crimes remain an important problem all over the world. Very few studies about sexual offenses in Turkey have been published. Sexual assault is a serious social problem that constitutes serious health conditions affecting the lives of involved individuals. In this study, we aimed to investigate socio-demographic features of victims, assailant-victim relationships and sexual assault findings. Material and methods: A total of 324 sexual assault victims presenting to and examined in the Department of Forensic Medicine, Kahramanmaras Sutcu Imam University Medical Faculty, between January 2007 and December 2010 were included in the study. The victims completed a survey at face to face interviews. Results: Of 324 victims, 268 (82.7%) were female and 56 (17.3%) were male. The mean age of the victims was 16.78 ± 7.16 years. In all cases, types of the assaults were as following; vaginal penetration in 160 (49.4%), anal penetration in 117 (36.1%), oral penetration with penis in 7 (2.2%) and in the form of kissing, fondling, touching the sex organ and rubbing the sex organ in 60 (18.5%) cases. Of all the assaults, 149 (46%) were found to take place in the assailants' homes and 49 (15.1%) in the victims' homes. Of 139 cases, 85 (26.3%) had genital injury alone and 54 (16.7%) had anal injury. Conclusion: On the contrary to the previous studies, this study revealed that sexual assaults occurred mostly in the assailants' homes and that the incidence of anal trauma was higher. © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Forensic medicine specialists take account of the projectiles remaining in the body when determining whether there are an equal number of entry and exit wounds. The absence of projectiles should suggest blank cartridges, a single exit wound despite several firings and bullet embolization, whereas the presence of more projectiles than expected may indicate tandem projectiles and multiple projectiles entering through the same hole. Radiological examination of the whole body, follow-up of the bullet trajectories, examination of the clothes, and examination of the gun and projectiles play a key role in solving difficult cases. We review such situations based on a case of tandem bullets. Two 7.65-mm bullets created lethal wounds entering through a 32-year-old victim's neck followed the same trajectory to a certain point and diverted. We discussed the possibilities in cases that show inequalities between entry and exit wounds, in light of relevant literature. © 2012 American Academy of Forensic Sciences.

Objective: Farm tractors are not only used as farm machineries but also as communication and transportation machineries in Turkey where agricultural production plays an important role. Tractor overturns end up with casualties especially if the structurally off-balanced tractor has no rollover protection structures (ROPS) or seatbelts. Serious manpower and economical losses also result from these kinds of accidents. Material and Methods: In this paper, all forensic death examination reports, autopsy reports and witness statement reports obtained in city center of Kastamonu between January 2004 and July 2009 were examined and evaluated statistically. Results: We observed 601 death cases during this period and found that 42 (6.98%) of them were related to tractor overturns, 92.86% of the cases were males and 7.14% of them were females. The range of age was between 17-80 years. 19.04% of the victims were passengers while the remaining were drivers. Most of the events (52.80%) have occurred on the roads. In a high percentage (54.76%) of the cases, cause of deaths was determined as chest trauma while abdomen, neck and head traumas were also observed in some cases. Conclusion: Although tractors are the most frequently used machineries in agricultural production of Turkey, casualties of tractor overturns do not attract much attention. These casualties are not negligible and necessary agricultural engineering strategies should be implemented immediately to prevent these unexpected accidents. © 2011 by Türkiye Klinikleri.

Background: Psychological autopsy studies have been widely used to identify the cause of suicide. However, gender is one of the most frequently replicated predictors for suicide. To identify further the significant risk factors for suicide among males and females separately. Method: Data were obtained from The Turkish-Istanbul Forensic Medicine Institute Morgue Department for all suicides deaths from April to August 2002 in Istanbul. 124 completed suicides were included in the study. Results: This study findings suggest that unemployed, not married or in a de facto relationship, previous suicide attempt, and alcohol or substance abuse were common amongst those who died by suicide. Most of the victims were male; the most frequent suicide methods were hanging and jumping down a high building followed by firearms. Both males and females were most frequently affected by psychiatric disorders. It was found that 108 cases that did not receive psychiatric care attempted suicide for the first time and committed suicide. Conclusion: This finding suggests that suicides should be investigated by an expert team and not by the police and victims' relatives only to determine whether they are really suicides or not. © 2012 Elsevier B.V.

A tetranitrile monomer was synthesized by nucleophilic aromatic substitution of N,N′-(2,2′-(propane-1,3-diylbis(sulfanediyl))bis(ethane-2,1-diyl))bis(4-methylbenzenesulfonamide) onto 4-nitrophthalonitrile. A metal-free phthalocyanine polymer was prepared by the reaction of the tetranitrile monomer under N2 in the presence of 2-(dimethylamino)ethanol at 145 °C for 24 h. Zinc(II), copper(II), cobalt(II), nickel(II), lead(II), phthalocyanine polymers were prepared by reaction of the tetranitrile with the chlorides of zinc (II), copper (II), cobalt (II), nickel (II), lead (II), employing microwave irradiation in the presence 2-(dimethylamino)ethanol at 175 °C, 350 W for 10 min. The thermal stabilities of the phthalocyanine compounds were determined by thermogravimetric analysis. The new compounds were characterized by a combination of IR, 1H NMR, 13C NMR, UV-vis, elemental analysis and MS spectral data. © 2009 Elsevier Ltd. All rights reserved.

The herbal products referred to as 'Spice' have been used as 'legal alternatives' to cannabis worldwide since 2004. The first synthetic cannabinoid JWH-018 was detected in 'Spice' products in 2008, and has been banned by many legal authorities since the beginning of 2009. In order to prove use of JWH cannabinoids (JWHs), specific and robust methods were needed. We have developed a specific and reliable method for the detection and quantification of JWH-018, JWH-018 N-pentanoic acid, and JWH-018 N-(5-hydroxypentyl) in blood and urine using solid-phase extraction followed by UPLC-MS/MS analysis. The method has been validated in terms of linearity (0.1-50. ng/mL), selectivity, intra-assay and inter-assay accuracy and precision (CV. <. 15%), recovery (85-98%), limits of detection (LOD) (0.08-0.14. ng/mL), and quantification (LOQ) (0.10-0.21. ng/mL). Matrix effects, stability, and process efficiency were also assessed. The method has been applied to 868 authentic samples received by the Department of Chemistry (Istanbul) in the Council of Forensic Medicine of the Ministry of Justice. © 2015 Elsevier Ireland Ltd.

BACKGROUND: Lower local recurrence rates and better overall survival are associated with complete mesocolic excision with central vascular ligation for treatment of colon cancer. To accomplish this, surgeons need to pay special attention to the surgical anatomical planes and vascular anatomy of the colon. However, surgical education in this area has been neglected. OBJECTIVE: The aim of this study is to define the correct surgical anatomical planes for complete mesocolic excision with central vascular ligation and to demonstrate the correct dissection technique for protecting anatomical structures. DESIGN AND SETTINGS: Macroscopic and microscopic surgical dissections were performed on 12 cadavers in the anatomy laboratory and on autopsy specimens. The dissections were recorded as video clips. METHODS: Dissections were performed in accordance with the complete mesocolic excision technique on 10 male and 2 female cadavers. Vascular structures, autonomic nerves, and related fascias were shown. Within each step of the surgical procedure, important anatomical structures were displayed on still images captured from videos by animations. RESULTS: Three crucial steps for complete mesocolic excision with central vascular ligation are demonstrated on the cadavers: 1) full mobilization of the superior mesenteric root following the embryological planes between the visceral and the parietal fascias; 2) mobilization of the mesocolon from the duodenum and the pancreas and identification of vascular structures, especially the veins around the pancreas; and 3) central vascular ligation of the colonic vessels at their origin, taking into account the vascular variations within the mesocolonic vessels and the autonomic nerves around the superior mesenteric artery. LIMITATIONS: The limitation of this study was the number of the cadavers used. CONCLUSIONS: Successful complete mesocolic excision with central vascular ligation depends on an accurate knowledge of the surgical anatomical planes and the vascular anatomy of the colon. © The ASCRS 2014.

Murder of women generally occurs as a result of violence by their husbands and relatives. We evaluated the female victims of murder in Eskişehir, located in western Anatolia, where the education level is high in this study. Our aim was to assess and discuss data related to the victims and murderers. A total of 141 women's murder cases were analysed in the study. After a legal process and the results of the autopsies during 2002-2011 in Eskişehir, 715 subjects found to have died as a result of murder were chosen. Cases were evaluated in terms of their age, marital status, education level, relationship to the murderer, reasons for violence, type of action and reasons for death. It was determined that 48.2% (n = 68) of the victims had been killed by the husband and 7.8% (n = 11) by the ex-husband. Murderers generally stated that the reason of murder was the woman's request for divorce or breaking up (n = 40, 28.4%). In compliance with the literature, the women were most commonly killed by their husbands in our study. Enhancing women's status and preventing violence against women will decrease such murders. © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.
