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.

A new publication, Fractional Operators with Constant and Variable Order with Application to Geo-Hydrology, will be published later this year, on 1 November 2017. The author, Prof Abdon Atangana, from the Institute of Groundwater Studies at the University of the Free State, said the book proposes new techniques for groundwater remediation, including guidelines on how chemical companies can be positioned in any city to avoid groundwater pollution.

Focus of the book
Prof Atangana said researchers and practitioners interested in groundwater modelling and remediation from applied mathematical and geo-hydrology backgrounds, will benefit from reading this book.

According to Elsevier, the book provides a physical review of fractional operators, fractional variable order operators, and uncertain derivatives to groundwater flow and environmental remediation. It presents a formal set of mathematical equations for the description of groundwater flow and pollution problems using the concept of non-integer order derivative. Both advantages and disadvantages of models with fractional operators are discussed.

“Researchers and practitioners
interested in groundwater modelling
and remediation from applied
mathematician and geo-hydrology
backgrounds, will benefit from
reading this book.”

About the author
Prof Atangana specialises in applied mathematics, groundwater modelling, fractional calculus and their applications, methods for partial differential equations, methods for ordinary differential equations, iterations methods, asymptotic methods, perturbations methods, and numerical method for fractional differential equations, uncertainties analysis. He has participated in 18 international conferences, organised six special sections and symposiums in international conference in Europe, Africa, Asia and USA, and has been invited as plenary speaker in eight international conferences. He also serves as editor on 20 international journal of mathematics and applied mathematics and editor-in-chief of two international journals of applied mathematics.
