Understanding technical debt: the hidden cost of ignoring problems

In today’s rapidly evolving technological landscape, businesses heavily rely on software and IT systems to drive their operations. However, the pursuit of efficiency and speed often leads to the accumulation of what is known as technical debt. Technical debt refers to the implied cost incurred when businesses choose quick but limited solutions over better approaches that may take more time to implement. This blog post will delve into the concept of technical debt, its implications for businesses and how to avoid falling victim to its detrimental effects.

Rescheduling a Schedule I substance, and the Delta-8 controversy

Rescheduling a Schedule I substance, and the Delta-8 controversy

Did you know that in the US, drugs and other chemicals are classified into 5 distinct categories depending on the drug’s acceptable medical use and its potential for abuse or dependency?  Drugs federally classified as Schedule I substances by the US Drug Enforcement Administration (DEA) are considered to have the highest potential for abuse and for creating severe psychological and/or physical dependence. In addition to heroin, LSD and MDMA (ecstasy), cannabis is classified as a Schedule I substance in the Controlled Substance Act of 1970, which means it has no approved medical usage.

Time for lunch? We don’t think so!

The Key to Measuring Chemical Dyes in Food is LC-MS/MS

The Key to Measuring Chemical Dyes in Food is LC-MS/MS

Adding colorful dyes to food is nothing new. In the early 19th century, for example, it wasn’t uncommon for manufacturers to add chalk to white bread, thicken milk with a lead compound, and inject red dye into meat in the quest for a fresher appearance1. Fast forward to the 21st century, however, and along with mass spectrometry, food standards have come a long way. Foods now must pass muster according to standards set by government regulators or else risk fines and punishment which can be costly for the manufacturer.  To support these measures, are agencies such as the US-FDA, EFSA, and others which have banned some colors due to their toxic and carcinogenic nature which brings me to mass spectrometry analysis. Discover more when you read the following application note, “LC-MS/MS Analysis of Emerging Food Contaminants,” in which researchers used the ExionLC AD with a Phenomenex Column for sample separation followed by MS/MS detection with the SCIEX X500R QTOF system.

What is your Method for Separating Challenging Polar Molecules?

What is your Method for Separating Challenging Polar Molecules?

From small ions like phosphate, herbicide degradation to metabolites, oligosaccharides, peptides, and proteins. How is your lab analyzing polar molecules? The reason I ask is there is a saying, if you have a charged or polar molecule, look to capillary electrophoresis (CE) first. While liquid chromatography (LC) is an ideal front-end separation tool for many types of molecules, as the following poster points out, “From Small to Very Large, Orthogonal, Sensitive Polar Molecule Analysis by CESI-MS,” there are some situations that call for CE over LC analysis. For those of you that are not familiar with CESI-MS, it is the combining of CE separation with electrospray ionization, into one dynamic process, within the same device.

The Trouble with PFAS in Drinking Water

The Trouble with PFAS in Drinking Water

There has been a string of news articles concerning polyfluorinated alkyl substances (PFAS) in drinking water these days, and I must say, they have my attention. Here is the thing, when you think of drinking water in the United States, for example, crystal clear lakes, rivers, and groundwater along with effective water treatment come to mind. On the flip side, as safe, some supplies may be there are communities such as that of Flint, Michigan, which have been dealing with lead filled pipes for far too long. Contamination was so bad there that residents were provided bottled water for drinking purposes as the state decided who was responsible for replacing the affected water lines.

The Power Behind LC-MS for Quantifying mAb Therapeutics

The Power Behind LC-MS for Quantifying mAb Therapeutics

Quantitation of monoclonal antibodies (mAbs) in biological fluids is important during all stages of antibody drug development. First developed in the 1970s, therapeutic mAbs have both research and medicinal impact as they can be used for diagnosis and treatment of a wide variety of diseases, and have a high level of specificity.

In an effort to Replace, Refine, and Reduce the number of animals used for pre-clinical research, several microsampling strategies have been implemented which allow for the consolidation of satellite TK and main study groups. In addition to the ethical gains driven by these 3Rs, microsampling has the potential of increasing scientific value since it becomes feasible to directly correlate exposure, toxicological effects and pharmacological response in the same individual

Using the X500R QTOF System and SCIEX OS to Identify and Quantify Food Residues

Using the X500R QTOF System and SCIEX OS to Identify and Quantify Food Residues

Farmers use pesticides to protect crops from insects and disease as pesticides are necessary to create the volume of food that our population requires. Without them, we would not be able to grow enough crops to feed the world—they are a necessary evil. Government agencies such the Food and Drug Administration (FDA) in the United States and pesticide manufacturers, however, work hard to educate farmers on how to minimize their use. However, sometimes farmers add too much which leaves a residue. Upon harvest, farmers wash the fruit and vegetables. Once complete the crop then makes its way to the wholesaler and eventually, the supermarket. Even so, there may still be pesticide residue on the produce, which is why government agencies randomly pull produce from store shelves for testing of maximum residual limits (MRLs) and we are encouraged to wash our food before consuming it

The World Has its Eyes on Precision Medicine

The World Has its Eyes on Precision Medicine

What if we could understand and then treat diseases on an individualized level, in a way that was tuned to a person’s individual biology? Not in a futuristic, ‘wave a high-tech scanner across a person’s body’ way, but in a legitimate ’I can run a lab test and know the best action to take’ way. This is the promise of Precision Medicine, to deliver the right treatment to the right patient, at the right time, predicting more accurately which treatments will work for certain groups of patients, in contrast to the pervasive one-size-fits-all approach. More specifically, if we could provide a comprehensive report at the molecular level of an individual (based on genome, proteome, or metabolome profiles), a physician could be much better informed to make optimal treatment decisions. And if we could track these profiles over time, a person could adjust their lifestyle to focus on long-term wellness.
