The Biological Effects of Kambo: Is There a Relationship Between its Administration and Sudden Death? 下载免费PDF全文
Isabella Aquila M.D. Ph.D. Santo Gratteri M.D. Ph.D. Matteo A. Sacco M.D. Vittorio Fineschi M.D. Ph.D. Simona Magi M.D. Ph.D. Pasqualina Castaldo M.D. Graziella Viscomi D.A. Salvatore Amoroso M.D. Ph.D. Pietrantonio Ricci M.D. Ph.D. 《Journal of forensic sciences》2018,63(3):965-968
Kambo is a substance obtained from the skin secretions of a frog, Phyllomedusa bicolor, popular in the Amazon region, which is administered via the transdermal route. We report a case of 42‐year‐old man found dead in his house. Near the corpse, a plastic box labeled as “Kambo sticks” was found. The man was a chronic consumer of Kambo and no previous pathology or genetic disease emerged in clinical history from the declaration of his general practitioner. Autopsy investigations and toxicological analysis were performed. The histopathological examination showed left ventricular hypertrophy. Toxicological screening was negative for ethanol and other drugs. Phyllocaerulein, phyllokinin, and deltorphin A were isolated from the Kambo sticks but, only deltorphin A was detected in blood sample. We describe the first forensic case of death associated with Kambo administration. We attempt to explain how its use could be related to the cause of sudden death in this case. 相似文献

Assessment of the Effects Exerted by Acid and Alkaline Solutions on Bone: Is Chemistry the Answer? 下载免费PDF全文
Alberto Amadasi M.D. Arianna Camici B.Sc. Davide Porta B.Sc. Lucia Cucca B.A. Daniele Merli Ph.D. Chiara Milanese Ph.D. Antonella Profumo Ph.D. Nabila Rassifi B.A. Cristina Cattaneo Ph.D. 《Journal of forensic sciences》2017,62(5):1297-1303
The treatment of corpses with extremely acid or basic liquids is sometimes performed in criminal contexts. A thorough characterization by chemical analysis may provide further help to macroscopic and microscopic analysis; 63 porcine bone samples were treated with solutions at different pH (1–14) for immersion periods up to 70 days, as well as in extremely acidic sulfuric acid solutions (9 M/18 M) and extremely basic sodium hydroxide. Inductively coupled optical emission spectrometry (ICP‐OES)/plasma mass spectrometry (ICP‐MS), Fourier transform infrared spectroscopy (FT‐IR), energy dispersive X‐ray analysis (EDX), X‐ray powder diffraction (XRPD), and scanning electron microscopy (SEM) showed that only the sulfuric acid solution 18 M was able to completely dissolve the sample. In addition, chemical analysis allowed to recognize the contact between bone and substances. Hydrated calcium sulfate arose from extreme pH. The possibility of detecting the presence of human material within the residual solution was demonstrated, especially with FT‐IR, ICP‐OES, and EDX. 相似文献

Detection of thiopental and pentobarbital in head and pubic hair in a case of drug-facilitated sexual assault 总被引:2,自引:0,他引:2
The quali-quantitative determination of two barbiturates, thiopental and its metabolite pentobarbital, in head and pubic hair samples of a woman who had been sexually assaulted during hospitalisation, is reported. Hair was analysed by means of solid-phase microextraction (SPME) and gas chromatography-multiple mass spectrometry (GC-MS-MS), in chemical ionisation conditions. Thiopental and pentobarbital were found in three proximal head hair segments (sample 1A: 0.30 and 0.40 ng/mg; sample 1B: 0.20 and 0.20 ng/mg; sample 3: 0.15 and 0.20 ng/mg) and pubic hair sample. Two distal head hair segments were negative for both barbiturates. Despite the lack of collection and toxicological analysis of blood or urine samples within the hospital setting, analytical findings from hair revealed the use of the anaesthetic agent thiopental to sedate the victim quickly and deeply and commit sexual assault. 相似文献

HLA-DQA1 typing of 227 randomly selected Northern Italian people by the use of polymerase chain reaction are reported. The combined use of commercial Amplitype HLA-DQalpha system and four sequence-specific oligonucleotide probes allows the definition of 8 alleles and 36 genotypes, arranged according to World Health Organisation nomenclature. Seven of these genotypes are not observed among the analyzed samples. Allele frequencies range from 1.5 to 35.7% and genotype observations do not deviate significantly from Hardy-Weinberg equilibrium; observed heterozygosity is 0.8238 with an allelic diversity value of 0.79 and the power of discrimination is 0.925. Our Italian population sample shows differences from other Caucasian samples both for allele and genotype frequencies. This locus typing for the 8 defined alleles provides a rapid and sensitive method in individual identification and paternity investigation. 相似文献

An increasing number of investigations have dealt with particular aspects of democratic consolidation in Latin America. The multitude of geographic, historical and social conditions underlying the process, however, have often constituted a formidable hurdle for comparative study and generalization. In this paper I undertake a preliminary screening of the existing data and present a summary of facts and theories on democratic consolidation in the region. After an extensive analysis of different sources, I compare the experiences of Latin American countries and define a series of factors that seem to facilitate the consolidation of new democratic regimes. These factors include the beneficial role of earlier democratic traditions, the negotiation of agreements among political elites, diffuse support for the regime, solid party systems, effective control over military participation in society and, to a lesser extent, a favorable economy, especially when accompanied by less unequal income distribution. 相似文献
