我国法律对性交易的打击虽非常严厉,但性交易却屡禁不止,并愈演愈烈.可见,我国现行的严禁主义存在问题.纵观我国历史大多数时期,性交易是合法的,并且性交易合法时期往往是社会环境比较宽松的时期,也往往是历史上的“盛世”之时.而性交易非法时期也往往是法律环境比较苛刻、社会控制比较严厉的时期.这样的时期里对性交易的管制往往就是严刑峻法,通过这样的管制也往往造成统治者不愿意看到的结果,并且最终都会放开对性交易的管制. 相似文献

The VNTR 3'APOB and D1S80 loci were studied in a sample of 179 individuals living in the Recanati Area (Central Italy). For 3'APOB, we found 34 genotypes and 11 alleles. The system was in Hardy-Weinberg equilibrium. The observed and expected heterozygosity were 0.788 and 0.798 respectively. The discrimination power was 0.96, the a-priori paternity exclusion power was 0.619 and the polymorphism information content was 0.773. For D1S80, we found 45 genotypes and 18 alleles. The system deviated significantly from Hardy-Weinberg equilibrium. The observed and expected heterozygosity were 0.696 and 0.790 respectively. The discrimination power was 0.96, the a-priori paternity exclusion power was 0.617 and PIC was 0.767. The Recanati sample was compared with the general Italian frequencies for the 3'APOB locus. A difference of borderline significance was detected (P = 0.04). For D1S80, the sample was compared with a sample from Southern Italy and no significant difference was detected. 相似文献

Abstract: Dr. Hawley Crippen was accused and convicted of murdering his wife in London in 1910. Key to the conviction was microscopic analysis of remains found in the Crippen’s coal cellar, which were identified as Cora Crippen based on a scar she was said to have. Dr. Crippen was hanged, always proclaiming his innocence. In this study, genealogical research was used to locate maternal relatives of Cora Crippen, and their mitochondrial haplotypes were determined. Next, one of the pathology slides of the scar was obtained, DNA was isolated, and the haplotype was determined. That process was then repeated. Finally, both DNA isolates were assayed for repetitive elements on autosomes and repetitive elements specific to the Y chromosome. Based on the genealogical and mitochondrial DNA research, the tissue on the pathology slide used to convict Dr. Crippen was not that of Cora Crippen. Moreover, that tissue was male in origin. 相似文献

Observations of high velocity bloodspatter on adjacent objects 总被引:1,自引:0,他引:1
In a recent homicide investigation, high velocity backspatter was observed on the sleeve cuff of the accused. These minute droplets were discovered only after microscopic examination and were limited in number. A study was initiated to determine if these were truly backspatter droplets or transferred blood produced from light contact with a bloody item. It was observed that the backspattered blood was primarily limited to contact or near contact shots. An exception was a shot into an already bloody surface. It was found that backspattered blood would deposit on the shooter's shirt sleeve irrespective of the weave pattern. Transferred blood was observed only on the fiber tops. This information was found to be useful in reconstruction of events in suicides as well as possible homicides. 相似文献

A 20-year-old woman was treated because of her complaint and symptoms which were thought to be the results or complication of her pregnancy. Based on the cardinal symptom inferior cavography was carried out, and the diagnosis of occlusion of inferior vena cava was established. The woman was treated accordingly but died after a short period. The patient's family supposed neglection and therapeutic misadventure and raised an objection to the medical treatment. Forensic autopsy was carried out to clear up the case. Autopsy showed her basic disease to be gastric cancer with several metastases in the liver. One of them was in the lobus caudatus Spigeli and compressed the inferior vena cava. The compression caused a turbulence in the given contrast material so that thrombosis was suggested. The diagnosis was based on this misleading sign. Negligence was not verified. 相似文献

Two autopsy cases, where the individuals were suspected of having ingested acephate, an organophosphorous insecticide, are reported. Acephate and its active metabolite, methamidophos (MP), were analyzed in the biological fluids by GC/MS, using the salting out method with liquid-liquid extraction columns. The first case was that of a 70-year-old man whose blood acephate was 149 microg/mL, and MP was 3.0 microg/mL. Serum pseudocholinesterase (ChE) activity was inhibited. No remarkable finding of injury or disease was determined as the cause of his death, but acute poisoning by acephate was mostly suspected. The second case was that of a 60-year-old man. A deep gash in the left neck injured the left common carotid artery in addition to the severely ischemic state of the primary organs. His blood acephate was 46 microg/mL, and MP was not detected. ChE activity was in the normal range. Hemorrhage was mainly suspected as the cause of his death. The concentrations of acephate and MP in human blood after oral ingestion are first reported here, and the acute toxic level of acephate is discussed. 相似文献

Rapid and simple sex determination method from dental pulp by loop-mediated isothermal amplification
Hiroaki Nogami Hirofumi Tsutsumi Toshinobu Komuro Rei Mukoyama 《Forensic Science International: Genetics Supplement Series》2008,2(4):349-353
Sex determination from dental pulp DNA was examined by loop-mediated isothermal amplification (LAMP) method. Amelogenin locus was analyzed for sex determination. A set of four specially designed primers was prepared based on database from Gene Bank, and loop primers were designed to shorten the analysis time. Analysis was performed using 32 dental pulp DNA samples removal from permanent teeth stored at room temperature for 1–25 years after extraction. The X allele was detected in approximately 32 min with real-time turbidimeter and the Y allele was detected in approximately 34 min. Analysis time was reduced to half when using loop primers. Visual detection was also possible as the amplified product showed white turbidity. Sex determination by LAMP method was rapid and simple, and it should prove useful in unknown bodies of mass disasters. 相似文献

A general toxicology unknown case is presented to demonstrate our systematic approach. A 20-year-old male was found dead with multiple suicide notes. Overdose was suspected but substances were not known. Blood alcohol was negative. Urine was analyzed by enzyme-multiplied immunoassay technique and was negative for all drugs assayed. Urine was then extracted with ethyl acetate:hexane (1:1) at pH 10 and back-extracted into 1.0N sulfuric acid. The acidic layer was adjusted to pH 10, and re-extracted with ethyl acetate:hexane (1:1). The residue was analyzed by gas chromatography (GC) on a 3% OV-101 column. It was found to be negative for all commonly screened substances. However, several unknown peaks were observed. Electron impact mass spectra of these unknown peaks were obtained and searched for in our computer library of more than 25000 mass spectra. These unknown peaks were identified as doxylamine and pyrilamine by gas chromatography/mass spectrometry. The base peak and molecular ion for pyrilamine were at m/z 121 and 285, respectively. The base peak for doxylamine was at m/z 58. No molecular ion was observed for doxylamine. Both doxylamine and pyrilamine are antihistamines, but are promoted and used in the management of insomnia. Quantitation was performed on a GC using dexbrompheniramine as an internal standard. Blood concentrations for doxylamine and pyrilamine were 0.7 and 7.0 mg/L, respectively. Concentrations in other tissues were determined. Death was caused by combined doxylamine and pyrilamine intoxication; the manner of death was suicide. 相似文献

A modified Poley's acid fuchsin-methyl green stain was used to demonstrate ligature marks in tissues taken at autopsy. This stain was compared in 30 cases with haematoxylin-eosin, Mallory's trichrome and Ogata's picro-indigocarmine stains. Using the modified Poley method, it was possible to demonstrate the compression mark in corpses even when post-mortem changes were advanced. The method was found useful in evaluating the cases when the force used was minimal or when the mark was atypical using the usual haematoxylin-eosin method. 相似文献

A reversed-HPLC method was established to determinate penicillins in whole blood. Thiamphenicol as internal standard was added to 0.5 ml blood. Proteins in blood were precipitated with acetonitrile, then the separate supernatant was directly injected onto the chromatography column. The range of five penicillins' linearities was 0.9918 to 0.9996, their range of relative recovery was 91.75% to 107.33%, their CV was 3.56% to 9.85%. Effects of different storage temperatures on the stability of analytes and interference of other antibiotics were also studied. 相似文献

Fifty serial killers who murdered for the primary goal of attaining sexual gratification, termed lust killers, were studied
to determine the prevalence of childhood abuse. Information regarding the childhood abuse sustained by each killer was obtained
primarily from biographical books, newspaper articles, and online sites. Abuse was categorized into physical abuse, sexual
abuse, psychological abuse, and neglect and was then compared to societal norms from 2001. Abuse of all types excluding neglect
was significantly higher in the serial killer population. For serial killers, the prevalence of physical abuse was 36%; sexual
abuse was 26%; and psychological abuse was 50%. Neglect was equally prevalent in the serial killer (18%) and societal norm
populations. 相似文献
