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.

Darwin lecture focuses on the genetic foundation of evolution
2009-05-22

 
The Department of Genetics at the University of the Free State (UFS) recently made their contribution to the story of life and survival by presenting two lectures on The genetic foundation of evolution. Prof. Johan Spies, Head of the Department of Genetics at the UFS discussed the variation that was created by mutations and how this variation was enhanced by re-combination. He also pointed out that these methods contributed relatively little to the gene pool of a species and that the expansion of the gene pool primarily took place by means of chromosome evolution. The latter also contributed to the creation of isolation mechanisms to prevent hybridism. He further emphasised the multitude of deviations of mendelian heredity, which contributed to more variation within a species.

Prof. Paul Grobler, Associate Professor from this department, next pointed out how natural selection played a role to form new species. He used various examples to indicate how the process took its course, for example, lactose intolerance. He also reported out that the man on the street mostly believed that Darwin with his theory of the survival of the fittest meant that the physically strongest species would survive. It was more a case of the one that could reproduce the fastest and the most, that would survive, he stated.

Present at the occasion were, from left front: Ms Letecia Jonker, student, Prof. Grobler, Ms Paula Spies, lecturer at the Department of Genetics and Ms Zurika Odendaal, junior lecturer at the Department of Genetics; back: Prof. Spies.
