Microcrystalline identification of selected designer drugs.

Forensic science international

Elie L, Baron M, Croxton R, Elie M.
PMID: 21889275
Forensic Sci Int. 2012 Jan 10;214(1):182-8. doi: 10.1016/j.forsciint.2011.08.005. Epub 2011 Sep 01.

A microcrystalline test for the detection of 4-methylmethcathinone (mephedrone), benzylpiperazine (BZP) and 5,6-methylenedioxy-2-aminoindane (MDAI) using aqueous solutions of mercury chloride is described. Each of the compounds investigated formed specific drug-reagent crystals within minutes. The uniqueness of the test was...

BACKGROUND: Indoor environments contain a broad diversity of non-pathogenic Basidiomycota yeasts, but their role in exacerbating adverse health effects has remained unclear.OBJECTIVE: To understand the role of Vishniacozyma victoriae exposure and its impact on human health.METHODS: A qPCR assay...

A new model to deliver scheduled outpatient care.

Archives of disease in childhood

Martin T, Hapca S, Mistry N, Steel R, Tse Y, Lumsden T, Crofton A, Turner SW.
PMID: 34893464
Arch Dis Child. 2021 Dec 10; doi: 10.1136/archdischild-2021-322394. Epub 2021 Dec 10.

Here we describe an integrated model for scheduled care (the 'cluster clinic'). Following a pilot in April 2018, cluster clinics were established across Aberdeen City from April 2019 but not the area surrounding Aberdeen (ie, Aberdeenshire). There were 2360...

Depyrogenation using Plasmas: A Novel Approach for Endotoxin Deactivation Using a Dielectric Barrier Discharge at Atmospheric Pressure.

Plasma processes and polymers (Print)

Bhatt N, Brier-Jones J, Trosan D, Brinkley C, Pecoraro J, Smallwood J, Crofton A, Hudson S, Kirsch W, Stapelmann K, Shannon S.
PMID: 34899113
Plasma Process Polym. 2021 Nov;18(11). doi: 10.1002/ppap.202100089. Epub 2021 Sep 07.

Developing a low-cost depyrogenation process is vital in extending medical applicability of polymers that can be used in medicine. We present an overview of the plasma-based depyrogenation literature and address the need to develop a non-thermal plasma-based depyrogenation process...

Reversing microcrystalline tests--an analytical approach to recycling of microcrystals from drugs of abuse.

Forensic science international

Elie LE, Baron MG, Croxton RS, Elie MP.
PMID: 21288671
