Forensic Examination of Heroin and Its Cutting Agents
In order to successfully counter the ever-growing drug problem, there is an increasing need, to identify conspiracy links and trafficking routes and to gather background intelligence concerning both the number of sources of drugs and whether those sources are within a country or are “internationally” based and also the points of distribution and distribution networks. A scientific tool to complement routine law enforcement investigative work in this field is the characterization and impurity profiling and cutting agents of seized drugs. Drug characterization studies have shown that it is possible to link samples, to classify material from different seizures into groups of related samples and to identify the origin of samples. Such information can be used for evidential (judicial, court) purposes or it can be used as a source of intelligence to identify samples that may have a common origin or history.

Poor Metabolic Quality Embryo is Capable to Implant – A Case Report
There has been little advance in embryo selection criteria since the first IVF. To this day, we select embryos by morphological criteria, which provide little information as to the actual embryo quality.
A Non-Contact Passive Approach for the Effective Collection of Target Explosive Volatiles for Canine Training Aid Development
The use of real explosive materials for canine training involves inherent dangers, toxicity risks exposure, and often limited availability of the training material all of which may affect the reliable training of canine teams. For this reason, the development of a training aid suitable for daily operations is beneficial to provide safe and effective explosive detection training that can provide for enhanced detection capabilities.
NMR Assignment of N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide Seized as Herbal Incense for the First Time in Italy
The synthetic cannabinoid, N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide, known also as AKB48 and/or APINACA, has been detected for the first time in herbal incense seized in Italy. Its structural characterization has been performed through gas chromatography-mass spectrometry (GC-MS) and high-resolution nuclear magnetic resonance (NMR) analysis. In order to favor an easier and faster identification of AKB48 in future investigations, NMR assignments in deuterated methanol and chloroform is also reported.
Headspace GC-MS Detection of Carbon Monoxide in Decomposed Blood and Hepatic Tissues
Here in a systematic, accurate and reliable method, Head-Space Gas Chromatography-Mass Spectrometry (HS-GC/MS) was developed to determine blood carboxyhemoglobin (COHb%), in order to investigate deaths related to CO exposure especially involving blood and hepatic tissues.
Identification of Designer Drugs using Gas Chromatography High-Resolution Mass Spectrometry and a Soft-Ionization Source
Gas chromatography-mass spectrometry (GC-MS) with electron ionization (EI) or chemical ionization (in positive or negative mode) plays an important role in the forensic analysis of designer drugs.
Toxicological Screening and Quantitation Using Liquid Chromatography/Time-of-Flight Mass Spectrometry
In recent years, an increasing number of new designer-drugs have increased the demands for general toxicological screening . Limited screening based on immunoassays is commonly used in clinical toxicology, whereas more comprehensive approaches are common in forensic toxicology such as screening based on Gas or Liquid Chromatography (GC or LC) approaches.
