Journal ArticleDOI
New method of derivatization and headspace solid-phase microextraction for gas chromatographic-mass spectrometric analysis of amphetamines in hair.
TL;DR: A simple method for hair analysis of methamphetamine (MAMP) and amphetamine (AMP) by gas chromatography-mass spectrometry (GC-MS) was developed using simultaneous headspace solid-phase microextraction (HS-SPME) with derivatization.
Journal ArticleDOI
Sudden unexpected death following stellate ganglion block.
TL;DR: There was professional error on the part of the doctor in the form of medical malpractice in the case of a 29-year-old woman who died 3.5 hours after undergoing stellate ganglion block (SGB).
Journal ArticleDOI
Headspace solid-phase microextraction and gas chromatographic-mass spectrometric screening for volatile hydrocarbons in blood
Junting Liu,Kenji Hara,Seiichi Kashimura,Masayuki Kashiwagi,Tomoko Hamanaka,Aya Miyoshi,Mitsuyoshi Kageura +6 more
TL;DR: This method is feasible for the screening of volatile hydrocarbons from blood in forensic medicine and can be used for examining a burned body to ascertain whether the victim had been alive or not when the burning incident took place.
Journal ArticleDOI
GC-PCI-MS/MS and LC-ESI-MS/MS databases for the detection of 104 psychotropic compounds (synthetic cannabinoids, synthetic cathinones, phenethylamine derivatives).
Brian Waters,Natsuki Ikematsu,Kenji Hara,Hiroshi Fujii,Tomoko Tokuyasu,Mio Takayama,Aya Matsusue,Masayuki Kashiwagi,Shin-ichi Kubo +8 more
TL;DR: Using a detection method that has been rarely utilized to analyze these types of compounds, gas chromatography with positive chemical ionization and tandem mass spectrometry (GC-PCI-MS/MS), 5 psychotropic compounds were detected in an actual forensic autopsy case.
Journal ArticleDOI
Application of the drowning index to actual drowning cases
Tomoko Sugimura,Masayuki Kashiwagi,Aya Matsusue,Kenji Hara,Mitsuyoshi Kageura,Shin-ichi Kubo +5 more
TL;DR: The drowning index (DI) was devised to diagnose drowning deaths, and is the weight ratio of the lungs and pleural effusion to the spleen, which is a valuable indicator.
