Investigation of the accumulation of 2,4-dichlorophenoxyacetic acid (2,4-D) in rat kidneys

The accumulation of 2,4-dichlorophenoxyacetic acid (2,4-D) and its metabolite 2,4-dichlorophenol (2,4-DCP) in the kidneys of rats was investigated. Male and female Sprague-Dawley rats were given 2,4-D in drinking water and food for 30 days. Group A (control group) was fed a normal diet, Group B was fed 50 ppm 2,4-D in 15 g food, Group C received 100 ppm 2,4-D in 15 g food, Group D received 25 ppm 2,4-D in 15 ml drinking water and Group E was given 50 ppm 2,4-D in 15 ml of drinking water. Levels of 2,4-D and 2,4-DCP in kidneys were determined using high performance liquid chromatography (HPLC). It was observed that at low doses of 2,4-D, the metabolite, 2,4-DCP found in the kidneys.     

Development of etching paste for serial number restoration on aluminum engine block

Engine numbers, which involve information regarding the engine type, production number, and year and place of manufacture, are used for identification purposes. Comprising of unique alphanumeric characters, the engine numbers are fully or partially obliterated especially in auto theft and smuggling cases to conceal the origin, identity, and owner of vehicles. The limitations of the current restoration techniques such as the difficulty of using chemical liquid etching in vertical sites, the restrictions of magnetic and optical methods, and the applicability of several techniques like electron backscatter diffraction only in the laboratory environment prompt the development of new techniques. In view of these limitations and the importance of restoring engine numbers in criminal investigations, this unique study aimed to develop an etching paste that would restore the effaced characters on a real aluminum alloy engine block. The characters which were cold-stamped on the engine block were milled at varying depths and restoration attempts were conducted using etching pastes formed with different chemicals and materials. The analyses indicate that the etching paste formed with 200 mg of perlite, 400 mg of iron powder, and 450 μL of 20 M NaOH provided restoration to a good extent. The prevention of over-etching through the controlling of the chemical reaction and the cost-effectiveness appears to be the advantages of this technique. The success of recovery on the real engine block, the facilitation of restoration on curved surfaces, and the chance of on-site usage will likely make the etching paste a widely used tool in serial number restoration.     

Cardiac Injuries Caused by Blunt Trauma: An Autopsy Based Assessment of the Injury Pattern

Abstract:  Nonpenetrating chest trauma with injury to the heart and aorta has become increasingly common, particularly as a result of rapid deceleration in high-speed vehicular accidents, over the past 2–3 decades. The high mortality rate of cardiac injuries and possible late onset complications make blunt cardiac injuries an important challenging point for legal medicine. One hundred and ninety cases with blunt cardiac injuries in a period of 3 years were analyzed retrospectively in terms of patterns of cardiac injury, survival times, and demographic profiles of the cases in this study.     

Suicide Among Children and Adolescents in a Province of Turkey

Abstract:  Despite well-documented increases in completed suicides among children, accurate knowledge of the characteristics of these suicides is very limited. The aim of this study was to investigate general characteristics of suicide among children and adolescents in the province of Istanbul and to evaluate obtained results in the light of the literature. Data were collected from autopsy records of the Morgue Department of Institute of Forensic Medicine, Istanbul. General characteristics of completed suicides among children and adolescents between 2001 and 2005 were retrospectively reviewed. The study included 176 suicides aged 9–19 years. The overwhelming majority of the suicides (92%) were aged 15–19 years. More than half of the suicides (60%) were male. The most frequent means of suicide was hanging (55%) followed by firearms (20%) and jump or descent from height (15%).     

Foreigners Dying in Istanbul

Abstract:  The study included 411 deaths selected from 14,647 medicolegal deaths autopsied in the Morgue Department of Forensic Medicine Institute Directorate, affiliated with the Ministry of Justice, between 1998 and 2002. Data were collected from court documents, coroner's investigation reports, and autopsy reports. The parameters of age, gender, nationality and origin, cause and place of death in foreigners dying in Istanbul were evaluated in the study. Out of 14,647 medicolegal deaths, 3.5% were foreigners from 34 different nationalities. The nationality with the highest rate of foreigner deaths (34%) was Romanian. Out of 411 deaths, 74.3% were male and 25.7% were female. Of all cases, 64.4% were tourists visiting Istanbul and 35.6% had a job in Istanbul. Of 146 foreigners employed in Istanbul, 94.5% did not have a work permit, while only 5.5% had a work permit.     

Agricultural policy in Russia and WTO accession

This article analyzes the implications of World Trade Organization (WTO) accession for Russian agricultural policy. Using Organisation for Economic Co-operation and Development (OECD) data on producer support from 2010, we identify two major characteristics of Russian agricultural and trade policy (a) reliance on sizeable differences between world and domestic prices to generate two-thirds of agricultural producer support and (b) highly distortionary budget support. We then consider whether the disciplines introduced by WTO accession will constrain or even roll back these distortionary policies, thereby substantially changing the nature of agricultural policies in Russia. Using data from OECD-FAO (Food and Agriculture Organization of the United Nations) and Russian Ministry of Agriculture projections, we conclude that the structure of OECD-type producer support in 2020 will be very similar to its current state. Market price support will continue to dominate the Producer Support Estimate, and the projected Current Total Aggregate Measure of Support (AMS) will approach the WTO Bound Total AMS (the ceiling on production-distorting support) only in 2018. For the reasons above, we conclude that although WTO accession provides opportunities for important changes in Russian sanitary, phytosanitary, food safety, trade, and tariff policies, membership is not a guarantee of systemic change. In fact, a serious look at Russian WTO commitments makes a minimum-change scenario quite possible and even likely.     

Computerized Image Analysis in Differentiation of Skin Lesions Caused by Electrocution, Flame Burns, and Abrasion

Abstract:  In the practice of forensic science, sometimes, it is not easy to understand whether skin lesion is due to electrocution and to differentiate the thermal burns and abrasion-type lesions, especially when electricity source cannot be revealed by death science investigation. Based on the causes of the lesions, cases were classified into three groups. Group 1 included 30 deaths from electrocution. Group 2 included 30 deaths with flame burns. Group 3 included 30 deaths from traffic accident cases, which had abrasions. In this study, epidermal nuclear area, perimeter, nuclear form factor, nuclear minimum axes, nuclear maximum axes, and minimum axes/maximum axes ratio were measured. As a result, we think that computerized image analysis beside light microscopic examination can be useful in the differentiation of the electrocution, flame burn, and abrasion type lesions.
