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.

Consumer Science at the UFS awards three PhDs

For the first time in its history, the Department of Consumer Science in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) earned three doctorates at one graduation ceremony this year. This week three PhDs were awarded to Ismari van der Merwe, Natasha Cronje, and Gloria Seiphetlheng at the Winter Graduation that took place on the Bloemfontein Campus.

Electrochemically-activated water is widely used in the food and other industries, due to its excellent environment-friendly properties. However, it is not used in the textile industry yet, because too little research has been done to determine the possible positive and negative impact it may have on textiles.

With the thesis, The evaluation of catholyte treatment on the colour and tensile properties of dyed cotton, polyester and polyamide 6,6 fabrics,  Dr Cronje, a lecturer in the UFS’s Department of Consumer Science, and Dr Seiphetlheng from the Serowe College of Education in Botswana,  provided major new information with the thesis, Anolyte as an alternative bleach for cotton fabrics. This information is essential when considering the application of catholytes and anolytes in the textile industry.

Electrochemically-activated water divides water in catholytes and anolytes. The anolyte part is used as a disinfectant and bleach. It is not really suitable for domestic use, as it can cause colour loss in coloured textile products. However, it can be used in the hospitality industry where white sheets, towels, etc., are used and washed on a regular basis.

The catholyte part of the water has properties similar to washing powder. It can also be used in the textile industry as washing liquid.

According to Prof Hester Steyn, Head of the Department of Consumer Science and supervisor of all three PhD candidates, this electrochemically-activated water is also very eco-friendly. “It has a short shelf life. If the electrochemically-activated water isn’t utilised, it returns to normal water that wouldn’t harm the environment. No water is therefore lost, and no waste products are released that would contaminate the environment,” she says.

Dr Van der Merwe’s research focused on Degumming Gonometa postica cocoons using environmentally conscious methods. A lecturer in the Department of Consumer Science, she demonstrated that simple and environmentally-friendly methods can be used with great success to procure wild silk from the cocoons of the Gonometa postica worms living in the camel thorn trees found in the Northern Cape and Namibia.
