Limits of the Lamendin method in age determination.

This study shows that epithelial attachment level, used as age determination criterion in Lamendin's method, is not reliable for adults of either sex above the age of 49 years with periodontal diseases in any quadrant. The underestimation of calculated age increases from 7 to 19 years with chronological age. On the other hand, the present paper confirms the pertinence of dentin translucency as an age indicator in Lamendin's method.

Years of life lost from suicide in China, 1990-2000

Suicide is an important public health problem in China: It is the fifth leading cause of death in China, and suicide in China accounts for over 30% of the world's overall suicide deaths. The substantial burden due to suicide has not been well recognized. This study aims to provide an estimate of the socioeconomic burden of the suicide problem in China in terms of years of life lost (YLL) and to discuss its implications. Suicide rates and the related YLL by age, gender, and region (urban/rural) from 1990 to 2000 were estimated using the most recent data from the Ministry of Health of China. The suicide rate in rural China was three times higher than that in urban areas. Suicide completers in rural areas shared 90% of total YLL. Rural women aged 25-39 years contributed the largest share of YLL. Our results show that some population subgroups contributed a disproportionate share to the disease burden of suicide. National strategies for suicide prevention should include targeted programs in catering the need of these specified subgroups in China.     

Operational oceanography in Indonesia

In 2005 Indonesian and European institutes joined to start the first step for the implementation of an Ocean Operational System in the Indonesian archipelago. The system will support the decision making process for the sustainable use of marine resources, providing useful information and added value products as well as a service for an improved management of the sea with high business impact to targeted groups as public authorities and commercial operators (coastal managers, fishermen, shipping companies). In this paper the System is shortly described with its potential benefits and economic and social impacts.

Visas and work permits: Possible global negotiating initiatives

We discuss global options for initiatives intended to ameliorate adverse impacts of visa and work permit systems used by national governments around the world. We first describe and document some of their effects, noting the relative lack of other research work on these issues. We then discuss proposals for a new and supplemental global visa structure which have been made as part of the Mode 4 GATS negotiations in the WTO, suggesting that the GATS/WTO may be an imperfect institutional location for negotiating on these matters. We then evaluate other approaches, including what realistically could be possible if a new body specifically created for global negotiation in the area were to be used.

Detection of diatoms in blood by a combination of membrane filtering and chemical digestion

An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically.     

The empowerment of Turkish governors within hybrid settings of public administration

The widespread reforms of Turkish public administration and the machinery of government from 2000s onwards resulted in a gradual delegation of certain state’s functions to local and non-state actors, through a gradual rescaling of the policy-making systems and a remarkable hybridization of governance logics. The relevant literature focuses largely on the rising role and importance of involving non-state actors rather than state officials in policy-making processes. The paper explains how the scope and the method of public agents’ influence adapt to the current context of so-called neoliberalization of public administration in Turkey. The paper discusses in detail provincial governors with regard to their relatively ‘disguised’ power in social and economic policies through new hybrid mechanisms.     

Experimental studies on the mechanism of ethanol formation in corpses

Various in vitro experiments were performed for the purpose of clarifying the mechanism of ethanol production in corpses. Whereas a negligible quantity of ethanol was produced in the blood alone, which was left at room temperature, the quantity of ethanol was slightly increased by addition of glucose to the blood. When saprogens were further added, the quantity was markedly increased. Various materials were added to blood-liver homogenates as specimens, and the mixtures were stored in an incubator at 37 degrees C. As a result of the addition of an antibiotic to the mixture every day, there was hardly any production of ethanol. When alcohol dehydrogenase (ADH) and reduced nicotinamide adenine dinucleotide (NADH) were added, ethanol production was slightly increased. When acetaldehyde was added first, ethanol production was inhibited the next day, but on and after day 2, the quantity of ethanol was more than that in the control material. When pyruvic acid was added first, the results were similar to the above. Pyrazole, cyanamide, and disulfiram completely inhibited the production of ethanol. Ethanol production in corpses is believed to take place through a pathway opposite to that of ethanol metabolism in the living body, under the influence of ADH, ALDH, etc., in saprogens using carbohydrates as substrates.     

Lewis typing of human saliva stains by enzyme-linked immunosorbent assay (ELISA) using monoclonal anti-Le(a) and anti-Le(b) antibodies

The Lewis blood grouping of human saliva stains could be detected by an enzyme-linked immunosorbent assay (ELISA) using anti-Le(a) and anti-Le(b) monoclonal antibodies with an avidin-biotin complex (ABC). The saliva stains (1.0 by 1.0 cm in size) were used as samples and not only could the Lewis substances of 57 individual stains be correctly typed by this method, but also it was clarified that there are several different secretion patterns of amounts of Le(a) and Le(b) substances in 3 individual Lewis types.     

Sex determination from buccal mucosa and hair root by the combined treatment of quinacrine staining and the fluorescent Feulgen reaction using a single specimen

In order to determine sex using a single specimen, buccal mucosa and hair roots obtained from male and female individuals were used. The specimens were first stained with quinacrine for the detection of the Y-chromatin, and subsequently were stained by the fluorescent Feulgen reaction using acriflavine for the detection of the X-chromatin. In the male specimens, the frequency of fluorescent spots of quinacrine-positive bodies was high, whereas that of acriflavine-positive spots was low. On the other hand, in the female specimens, the frequency of quinacrine-positive spots was very low, while that of the acriflavine-positive spots was high. These specimens were air-dried and were allowed to stand at room temperature for periodical observations. The result was that sex difference was distinguishable for 4 months by the combined treatment method.
