Written procedures used by trained staff are the basis for all quality systems but there are many ways of writing a procedure. Are you getting it write?

The HPLC 2012 conference was abuzz with talk of "slip flow" following the talk given by Mary Wirth of Purdue University about her groundbreaking work involving protein column efficiency. In this interview, Wirth explains how “slip flow†works and what this discovery can contribute to the application of LC-MS to disease research.

Holistics evidence

Essential oil inhalation is a holistic and economic treatment for the alleviation of anxiety. Whether this effect is of a psychological or physiological basis has been in dispute since the beginnings of ‘modern’ medicine. Many would argue that any effects felt are simply psychological, a ‘placebo’ effect, as if the individual believes the treatment will aid them it does.

Urinary excretion profiling is a key element in the pharmokinetic characterization of new chemical entities (NCEs). Recent advances in ultra-high performance liquid chromatography (UHPLC) column technology offer improved results for liquid chromatography tandem mass spectrometry (LC–MS¬–MS) analysis, enabling rapid quantification of specific drugs and their metabolites in biological matrices.

Lethal bite

Malaria is the 5th responsible cause of death from infectious disease worldwide, and approximately half the global population are at risk. 1A team of scientists in Missouri, USA3 has recently answered a long-standing question regarding the metabolism of the parasite, advancing research towards identifying novel therapeutics

Hydrogel delivery

Drug bioavailability, the rate at which the active compound of a drug becomes available at the site of action, is key to the successful development of new drugs. The development of hydrogels, self-assembling polymer-based scaffolds, has rapidly accelerated in recent years because of their potential in the improvement of drug bioavailability.

Fishing for antidotes

Organophosphates (OPs) are commonly found in commercial pesticides and are highly toxic to humans if inhaled or ingested, resulting in both behavioural and psychological symptoms. OPs chemically modify the essential protein acetylcholine esterase, which is principally responsible for the breakdown of the essential neurotransmitter acetylcholine.
