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.

UFS teams up with Department of Agriculture and donates latest farming technology to Oppermans

Emerging and commercial farmers of the Oppermans Community in the Northern Cape will now be able to monitor the salinity levels on their farms effectively for the first time.

This is as a result of a donation of the latest technology that measures the salinity of soil – the EM38 system – which the University of the Free State (UFS) is donating to the community.

The unique project was launched by the Department of Soil, Crop and Climate Sciences at the UFS and the Department of Agriculture in the Free State during an information day held at Jacobsdal recently.

The day was attended by members of the Oppermans Community and representatives of the UFS as well as the Department of Agriculture. Mr Sugar Ramakarane, Head of the Department of Agriculture in the Free State, did the welcoming and several academics from the UFS held discussions about various topics related to the salinity levels in soil.

Since the establishment of the Oppermans Community emerging farmers are now for the first time able to accurately monitor the salinity levels on their farms as well as that of irrigation schemes of commercial farms in the area.

“In a region such as the Northern Cape it is very important that the salinity level of soil is monitored properly. As water is administered to crops, salts accumulate in the soil because the roots leave most of the salts in the soil when it transpires. When the salinity of soil increases, the osmotic potential thereof can also increase, which can seriously damage the water intake of crops and can create loss in yield and income,” said Prof. Leon van Rensburg from the Department of Soil, Crop and Climate Sciences at the UFS and leader of the Oppermans Project.

To assist the farming community of Oppermans to apply precision farming and to measure the salinity level of soil more accurately the latest technology that measures salinity in soil – the EM38 – will be donated to the community. Although the system is used throughout the world, the UFS is the only tertiary institution in the country that owns the latest version of this system.

“We are also training two persons from the Oppermans Community as technicians that will monitor the use of the system. The advantage of the donation of the system for the university is that we can gather data that can be used for research purposes by our Master’s and Doctoral students. We also want to see if water-table heights can be measured with this system,” said Prof. Van Rensburg.

According to him the system has several advantages for the community’s emerging farmers. “For the first time the salinity level of soil can now be measured accurately, salt maps can be drawn up, we can advise farmers about the corrections that need to be made and salinity management plans can be compiled,” he said.

The system is very accurate as it takes measurements every 200 mm while it is pulled by a four-wheel motorbike. The readings provide the distribution of salts up to a soil depth of 1 500 mm. “In the past the measuring of salinity levels was time-consuming and the cost thereof was R90 for one sample. The new system is more cost-effective,” stated Prof. Van Rensburg.

The instruments will be handed over to the African Spirit Group of the Oppermans Community, who will then become the owners. The service to farmers will then be managed by an operational group consisting of people from the Oppermans Community, a postgraduate student who can compile salinity maps and Prof. Van Rensburg, who will act as project leader and advisor.

The system will also be made available to farmers at the Riet River and Vaalharts Schemes.
