Fletcher Hiten, Chief Bioanalyst at FARMOVS, next to Aurora.

The Bioanalytical Services Division (BASD) at FARMOVS comprises a group of skilled and passionate scientists involved in the quantification of drugs, metabolites, and biomarkers in various biological matrices. One of their Analytical Science experts, Fletcher Hiten, explains what sets their team apart from the rest.

“Over the past 47 years, we have developed almost 600 validated assay methods. Most of these methods are for the analysis of ‘small’ molecules using chromatographic techniques such as LC-MS/MS, GC-MS, and HPLC, although LC-MS/MS is the technique of choice. New bioanalytical assays are continuously being development and validated in adherence to international regulatory guidelines set by the US-FDA and European Medicines Agency (EMA),” says Hiten.

“Recently, we decided to enhance our capabilities by recruiting exceptional talent. The newest member of the FARMOVS team is Aurora, a SCIEX Triple Quad™ 7500 LC-MS/MS mass analyser. Aurora is Latin for ‘dawn’: the beginning of a new era, especially one considered favourable. The SCIEX 7500 is currently marketed as the most sensitive triple quadrupole mass spectrometer available, allowing for sub-picogram/ml quantification. This means that Aurora will set FARMOVS apart from other clinical research organisations (CROs), creating an exciting and favourable landscape for clients to explore new partners in research.” 

Hiten stated: “If there was ever a time to move your next study to FARMOVS, it is now. To have Aurora on our team has many advantages, given that our clients can access unprecedented analytical sensitivity, which enables the quantification of pharmacokinetic (PK) profiles of drugs that have very low systemic absorption. These include predominantly local acting drugs, such as plasma concentrations of respiratory drugs (e.g., tiotropium and ipratropium), topically applied creams and ointments, and ophthalmology drops with ultra-sensitivity.”

“In addition, the quantification of drugs in low-volume matrices will also be exponentially enhanced, enabling the quantification of body fluids, where only a few microlitres can be collected, for example vaginal fluid, dried blood spots, cerebrospinal fluid, aqueous humour, synovial fluid, and epidermal micro-dialysis lysate – to name a few. The quantification of absorbed exogenous drugs into tissue, like vaginal biopsies and hair follicles, is also possible,” added Hiten. 

“And finally, multiple analyte analysis. In this case, the collected blood sample needs to be split into multiple aliquots for analysis, for example drug-drug interaction (DDI) studies with the Basel cocktail. The smaller sample volumes will allow more frequent sampling to be feasible and thus more accurate DDI interpretation,” Hiten explains.

“As a bio-analyst, one is seldom surprised. However, Aurora has already opened doors to new frontiers for our entire team and we cannot wait to do some more exploration,” says Hiten.

Inaugural lecture focuses on Plant Pathology
2005-08-16

Prof Neal Mc Laren, from the University of the Free State’s (UFS) Department of Plant Pathology, will deliver his inaugural lecture on Wednesday 17 August 2005 at 19:00 in the CR Swart Auditorium on campus.

The topic of the lecture is Beyond the pathogen:  revisited”.

Prof Mc Laren obtained his B Sc, B Sc (Hons) and M Sc (Agric) at the University of Natal and    Ph D (Plant Pathology) from the University of Pretoria.  In 1977 he was appointed as a research technician at the former Department of Agricultural Technical Services, was promoted to professional officer in 1983 and in 1995 to specialist scientist at the Agricultural Research Council.  In 2003 he was appointed as Associate Professor Extraordinary in the Department of Plant Sciences at the UFS and in 2005 as a full-time Professor of Plant Pathology. 

Prof Mc Laren has published 32 papers in accredited scientific journals or refereed proceedings which include two feature articles.  He also has three book chapters to his credit.  He has presented 35 local and 18 international conference papers and has been an invited/keynote speaker on a number of occasions.  He has published 26 popular articles, co-supervised several post-graduate students and been an examiner of a number of dissertations/theses.   He has acted as referee for numerous journal articles and was associate editor for African Plant Protection. In 1998 he received the ARC-President’s Award and in 1999, an award from the Sorghum Producers Organisation of the USA for outstanding research.

Prof Mc Laren’s principle area of interest has been diseases of sorghum with emphasis on ergot, damping-off and seedling blights, root rots and grain molds.  In addition, root rots of maize and more recently, soybean rust have received attention.  He has a particular interest in quantitative epidemiology.
