Subjects were composed of 12 flashbackers, 8 non-flashbackers, 13 MAP users who were not experienced MAP psychosis, and 15 MAP non-users. Flashbackers and non-flashbackers had previously all experienced MAP psychosis. Flashbacks were mostly triggered by mild fear of other people. Plasma norepinephrine(NE) levels were higher in 12 flashbackers during flashbacks than during periods of normalcy. Also plasma NE levels during flashbacks were higher than those in the 13 users and 15 non-users. Plasma NE levels in flasbackers during periods of normalcy were higher than those in the 13 user controls. Other monoamine metabolites concentrations in blood plasma were not significantly different among the subject subgroups. These results suggest that repeated MAP use with threatening experiences may produce sensitivity of neurotransmitter systems including noradrenergicsystems to psychosocial stressors at pharmacologic levels. An increase in peripheral noradrenergic activity may be related to occurrence of flashbacks.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126452936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Marumo","doi":"10.3408/JASTI.7.95","DOIUrl":"https://doi.org/10.3408/JASTI.7.95","url":null,"abstract":"Soil can provide important information to criminal investigations as transfer evidence because many criminal cases take place under circumstances such that soil transfers to a criminal or victim. The variation in soils from place to place makes soil valuable evidence to prove linkage between a suspect and a crime scene. Soil is a complex mixture with a variety of mineralogical, chemical, biological, and physical properties. Considering such complexity, a variety of methods have been developed for forensic science purposes. Because minerals are an important component of soils, mineralogical examination is essential in forensic soil identification. Additionally, many other methods can be applied to raise the discriminating power, but not all kind of methods need to be used. What is important is that examiners select an appropriate combination of methods by considering the context of the soil samples. This report summarizes a wide range of reports on the analysis of soil components and of closely related materials such as plant fragments, pollen and spores, and diatoms, with emphasis on the importance of screening tests consisting of several simple techniques. The soil formation process involves parent materials, temperature, water condition, vegetation, time, and the chemical processes of solution, oxidation, reduction, and even human activities. The history of a soil's development as the results of such complex soil formation process is strongly reflected in soil color. The systematic observation of multiple soil colors is especially useful for screening.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127327626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Finger/Palm-print Live Scanner equipment (Live Scanner) has been introduced to the local police stations for fingerprint collection operation. Fingerprint Live Scanner devices have been used as an authentication technology for security systems. The resolution of the Live Scanner image needs to be equal to that of all Live Scanner devices. For example, the required resolution for the police is about 20 points per mm so that sweat glands on a ridge can be distinguished. We developed a method of image correction to satisfy the requirements for the Live Scanner. Correcting methods for a degraded image such as the inverse filter and the Wiener filter had been proposed. But we are not able to estimate the resolution using the filter designed by these conventional methods. Because these conventional methods use the Signal to Noise ratio as a parameter and don't use relationship to the resolution. We applied the filter design method that we had developed for a satellite image, to correct the Live Scanner image. The method can evaluate a relationship between the filter effect and the filter parameter by point spread function (PSF). The proposed filter optimization method reduced the full width at half maximum of PSF about 36%, resulting in an improved resolution. With this method, sweat glands on a ridge can be distinguished.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129559798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have applied some monoclonal antibodies to hemagglutination test, enzyme-linked immunosorbent assay (ELISA) and absorption-elution test. Hemagglutination titer of these antibodies distributed ranging from ×4 to ×512. All antibodies examined could be used for detecting ABO blood type from secretor's saliva by ELISA method and using five anti-A antibodies blood group substances could be detected from non-secretor's saliva. Using anti-A and anti-B antibodies blood type could be detected from secretor's semen but using any antibody blood type could not be detected from non-secretor's semen. We could not get a correlation between hemagglutination titer and sensitivity on ELISA detected from saliva and semen. At absorption-elution test, using most of the anti-A and anti-B antibodies blood type could be detected of bloodstains and secretor's body fluid stains. Using several antibodies blood type could not be detected of non-secretor's samples. Using all of anti-A antibodies and some of anti-B antibodies it was failed to detect blood type of hair samples. Using all of the anti-H antibodies blood group substances could not be detected of stain or hair samples. This result suggested that we have to select suitable monoclonal antibodies of ABO blood grouping for each evidential sample and each blood typing method.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124375806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
